[Maid] maid of the house should have to ask a few? (CPU concept papers)
---------------------------------------- ----------------------------------------
[PC] CPU dual-core and single-core mode of operation (the maid of the concept papers)

Q. CPU dual-core and single-core What's the difference?
Q. dual-core than single-core fast?
Q. I have in the end there is no need to switch to dual-core?

CPU has developed into a dual-core now
In order to comply with the theme of this site, we are on the concept of dual-core to be easy to understand the interpretation of it ...

Dual-core CPU is like your family, please, two maids,
Single-core CPU as if you only invite a maid at home!

1. Single-core CPU processing mode of operation:

Your computer to work together under the command or the implementation of a program,
Like you are the maid of the house only under a command: [dinner time to go cook!]

Instruction in the implementation of the first period of the procedure has not yet been completed,
Then you have to continue under the second order or the implementation of other programs on the CPU to do different requirements ...
This is like a maid to cook a meal period,
And as the masters of the door you just have to go home, rang the bell has been to urge her to open the door ...

Of course, single-core CPU as the maid of the house that the only general,
She can do no more things...

She may cook stir-fries to half
Edge holding a bowl out of the door to help you open a door on another running back to rush the cooking,
When you want to put hot water bath, you may also have been yelled, waiting for her to take hot bath ~ ~ ~

CPU that it can deal with the efficiency of multi-tasking is to determine the limits of CPU utilization,
You any new instructions or programs you have previously issued an order steal CPU usage ...

The problem is that some software programs do not know how to control the operation of sense of propriety,
Once occupied by excessive CPU resources, the utilization rate of depletion of your CPU,
Whether you want to do other things more urgent, simply to you, regardless of resources,
You also find it hard to single-core CPU, specifically for you to deal with the requirements of the latest!

For example,
When you are dealing with a digitized image files, such programs consume enormous resources,
Even if you just want to open a small software for other things, the computer at this time is to move very ...

Used to describe real-life, then
As you also requested the maid of your home to create a kennel and go to Japan to buy the latest inflatable doll,

At this time you have finished taking a bath were found locked in the bathroom when
How can you yell you have no one to rescue rationale is just the same!

2. Dual-core CPU processing mode of operation:

Our maid to do the same metaphor, dual-core CPU as your home, please two maid!

Dual-core CPU price performance ratio, is not better than single-core,
However, it has a good division of labor model.

The normal operation of the program together by the two core support and sharing of work.

However, any time, even if the operation of the program no longer busy,
If you order a new command or open a new program,
There must be a core, specialized priority currently requires the latest program the operation of the main window;

In other words,
One maid may be responsible for dealing with you before many of the command,
She may be under repair leaky roofs , and clean windows, and sweep the floor,
Also ready to go out to buy high-speed rail tickets, have to go to Japan to buy two sets of parallel Wii back to the master ...

Another maid, equivalent to a secretary-type surrounded,
Usually if you do not have the new command, she will be another maid to help you explain the completion of the common things
But she is more important and the absolute priority is: available to your disposal!

If you are a home owner, she goes to immediately open the door,
You walked into the door immediately to help you prepare slippers, you begin to take off coat she reasdy to hang up properly,
Are you prepared to take a bath, she would put away the hot water ...
If you fell asleep, she will go to the help of another maid other work together,
She will, as you carry the Secretary of the model, to immediately complete the mandate entrusted to you!

In other words, the dual-core CPU, no matter how many months before the implementation of the program software,
Also there are bound to be one of the core, specifically to meet you at any time of the latest instructions or programs.

Even if your entire hard drive are engaged in the production of compressed files in the handling of state,
At the same time to look at animation, is that the election open the file, CPU immediately allocate resources
Nature does not play audio and video files over the delay, it will not neglect the requirements of your latest ...

3. CPU single-core and dual-core needs:

Q. CPU dual-core than single-core fast?

That did not, as long as you are willing to spend money, there is also a single-core CPU processing speed soon!

(Like you need to do is willing to spend money, please a young maid, Grandpa will be more than please the two-class, quite a lot faster maid!)

Q. Well, what computer users, more need to use dual-core CPU's?

If you often use some super eat CPU resources programs,
But the opening of the implementation of a CPU-type of software, you will be running the CPU usage to 100% did not fall,
And you often have to use the computer to do other things,
Do not want to wait for computers to handle other chores until the end of your turn, then ...

You do not want to assemble two computers,
Well, this is very suitable for your use of dual-core CPU person.

(To employ maids, in addition to family-type maid outside,
If you still need to type maid Secretary, then please let the two maid!)

[Computer] to buy a new hard disk, formatted with the transmission rate and transmission interface experience ...

Before the hard disk space is often inadequate, often want to download several files, it is necessary to delete some old files.

recently after look a BT Web site,
Suddenly found itself hard disk space really stretched to the limit
Had no choice but to buy the hard disk on the Internet!

1. The hard disk to buy:

A new Seagate hard disk Barracuda ES, enterprise or server application.
A look at the election of the election, xxx G price of about xxxx dollar, compared to other hard disk capacity can be regarded as a more cost effective
will not like 250G there are mines version (only 8MB cache) ...

If the hard disk durability point of view, the

I would suggest to buy seagate Barracuda ES series, (a dedicated server and enterprise storage)
Because he's Mean Time Between Failures (MTBF) has 1.2 million hours.

Originally available in the market Barracuda 7200.10 series,
MTBF only 700,000 hours.

However, MTBF is what I totally do not understand the meaning of, and
Mean time between failures?
Means that the whole hard drive all the parts damaged the average amount of time?
Or the read-write head can not speak to the average time spent?

However, the above data, I do not bother to care about,
Because of the hard disk of the data are measured on a good environment to do experiments, and

If You deliberately put it in a damp environment, the non-use of placing a few months, there will be a bad track ...

Moreover, the hard disk and general household electrical appliances are not the same,
As long as the hard disk to use several of them appear bad rail track, it is already warning of the deadly,
No way to use the entire hard drive to smash or blow up the stars so far ...

In short, ES version of the hard disk than is generally more expensive,
You can reference to see whether to buy ES version to strengthen the durability of the hard disk ...

PS.
Seagate suggest that you can buy this ST3320620NS models 320G SATAII 16M cache.

2. How fast hard disk transmission interface, often is a pretext:

Of course, this time I was a bit smarter
I already know the Sata II hard drives Seagate has a jump must be extracted,
Do not unplug the Sata 1 interface can only transfer 150MB / s,
Pulled out after Sata 2 interface will be able to transfer 300MB / s.

Of course, the rapid transmission of the hard disk interface probably just a gimmick,
Few people like me, with three running RAID0 hard disk and
Various brands in general single hard disk to read and write speed of only 45 ~ 75MB / s,
Sata 16 to his speed is wasted ...

For me, pulled out the small jump in the difference in mood, in essence, the performance is far greater than the differences!

3. Hard disk allocation unit size and speed relationships:

Then was to study how to format the hard disk and cutting, and
In the [My Computer] Right-click -> Select [Management] -> select the storage [disk management]

Early in DOS mode, marked FDISK,
The project now will be able to buy your new hard disk formatted to do action, and

Installed correctly in your circumstances, there will be more smoke should be a non-formatted disk, and
Please note, do not format to your disk is being used (hard disk).

For too long not to format the hard disk, did not expect that there are still points [basic] and [dynamic] disk mode
Simply put, [dynamic disk mode] is the number of stars under the hard disk to simulate using software RAID.

I already have the use of hardware RAID, and do not need to use WINDOWS software simulation RAID,
Therefore, direct election on the [basic] model of the.
If there is a need for software RAID, and may choose to use [dynamic disk].

Officially began when formatting the hard disk, a NTFS [configuration unit size],
There are 512 (0.5K) ~ 64K can choose ...

I suddenly thought of the past are choosing [default], the problem is the default value is how much ah?
Internet search to know the default is only 4K.

I used to have lost sight of the basic unit of the cluster with the value of this option is a waste of hard disk space and decided to speed the implementation of the key

Speed and space can not have both,
You want the implementation of fast hard disk, you must compare a little more than a waste of hard disk space;
You want to save hard disk space, but the hard disk will let you run more slowly!

However,
The basic principles of the decision or recommendation depends on how much you usually put the file in your hard disk:

If you often carry a large hard disk audio and video files (1M ~ 1G above),
That basic disk [configuration unit size], on the appropriate electoral larger 64K,

If you are frequently loaded with medium-sized hard disk image file (100K ~ 1M),
That basic disk [configuration unit size], on the appropriate electoral 16K or 32K,

If your hard disk are often loaded with small text file (1K ~ 100K),
That basic disk [configuration unit size], suitable for smaller election 4K or 8K.

4. The hard disk of the bottomless pit:

Finally, the 320G hard disk, the actual calculation is also nearly 298G only about space,
I chose to 32K for the basic unit to reformat the entire hard disk stars before started to play this article
The article has been finished at this time, up to now not be completed format (hard disk was big enough) ...

Do not know how long this hard disk will be filling it!?

PS.
I found that most single general internal hard disk transfer rate only in the 60MB / s up and down,
If we do not use more than 3 hard drives running Raid 0, then
In fact, in a computer inside the use of SATA (150MB / s), IDE (133MB / s) interface lacks all the difference ...

If the hard disk to buy an external interface on the free external use,
General external USB2.0 interface and two eSATA,

I actually tested with USB2.0 interface external transmission can reach 30MB / s,
USB2.0 standard and thus fail to half the speed of ...

If a large number of regular external hard drive to transfer files, then
Recommendations should be adopted or eSATA interface
Or directly into the motherboard SATA interface hard disk to transfer to reach the standard rate ...

[Computer] purchasing power supply (PSU) the key to efficiency

When you purchasing power supply (POWER SUPPLY),
The most important thing is not it better not look good, but its conversion performance (efficiency)!

Power supply, I think, is a computer components in critical parts,
Because of its control over the entire life span of computers and electricity differences
Little attention, only a few in order to save a few, may be a large sum of money you lost!

As for power supply of computer parts protective measures I will skip on this,
On this special [conversion performance] (efficiency)!

Because the power supply will be converted into AC DC, they are unable to 100% of the non-depletion of conversion,
Often have some power during the conversion process into the loss of heat and lost,
Conversion performance (efficiency), the better the power supply, the more is not easy to waste energy,
At the same time, more will not produce more heat.

Conversion performance (efficiency) refers to:
Power supply will put your wall next 110V AC power into the main computer to use the DC,
This conversion process, the converted DC power output divided by the total conversion of the former AC total power input,
Value is derived from the performance or efficiency (Efficiency).

Performance (efficiency) = converted output power / input power conversion before

I used the vernacular speakers Well,
Your home computer the power to spend money is not one hundred percent are consumed in the use of computers themselves out,
May be only 50% ~ 85% of electricity is a real role to play,
Other 50% ~ 15%, into a hot air emissions in the air, electricity wasted on this white ...

Suppose you actually used the computer must be consumed 250W of power,

(i) If you bought a good conversion performance power supply, the effectiveness of the assumption that 80%
Then you actually electricity consumption: 313W
(313W * 80% = 250W)

(ii) If you bought a conversion inefficient power supply, the effectiveness of the assumption that 65%
Then you actually electricity consumption: 385W
(385W * 65% = 250W)

If,
Life of each power supply can reach 24 hours the normal operation of 3 years (equivalent to 26,280 hours).
power consumption in a computer case:

80 percent efficient power supply power for:
250/80% * 26280 = 8212500 w hr = 8212.5 kw hr = 8212.5 degrees

65 percent efficient power supply power for:
250/65% * 26280 = 10107692 w hr = 10107.7 kw hr = 10107.7 degrees

Well, the performance of 65% compared to 80 percent efficiency power supply,
250W continuous power in the computer using the 3-year case, there will be more to eat you:
10107.7 - 8212.5 = 1895.2 kWh

I would like to 1 unit of electricity to 2.5 yuan if calculated in terms of three years would be tantamount to more than 4738 yuan spent electricity.

(Even if only for one year alone, more than a waste of electricity on up to 1579 yuan,
Enough to buy a good power supply efficiency.)

If you know your purchases in the market of more than 300 W power supply,
The efficiency of your point is also good to more than 1600 yuan, and efficiency may be poor spread only 500 yuan,
You may only to the immediate province of these 500 million, but the future, but will let you lose more than 4738 yuan in electricity ...

Of course,
You go to the roadside seized a medieval overcharging overcharging of power supply, even if the province did not need to pay a 1,500 yuan,
Only 50% of the effectiveness of the event, then there would be a more tragic;
250W of electricity in the computer case, three years later than the performance of your 80% of the power supply,
4914.36 pay electricity, which is the equivalent of 12,286 yuan of electricity ...
But with longer, you lose the bigger!

So, do not penny wise and pound foolish,
Power supply, or buy converter performance (efficiency) can be real good to save money ...
Do not bring precious power and coin in your purse, wasted on unnecessary waste of!

Incidentally,
As each power supply performance (efficiency) number,
It shall decide to refer them to the official website of various models of efficiency Efficiency data.

If you can not find relevant data on the efficiency of Efficiency also anxious to buy,
Had no choice but to directly buy Active PFC (Active Power Factor Correction) in POWER.

Although the Power Factor Correction (PFC) level does not mean that the level of efficiency Efficiency,
However, the usually active Power Factor Correction (A-PFC) series will have a very good efficiency.

Remember to buy [Active PFC], do not buy [passive PFC] or [non-PFC] and
Active PFC have identified the characteristics of a good,
Is near the back of the power switch, there is no red in 110V-220V switch.

Of course,
If you now go to the back of the computer case and found that your power supply switch above small switches,
It means that your power supply efficiency that should be poor~ ~ ~
In case you are prolonged use of computer,
Well, I suggest you rush for a number of stars efficient POWER, not the province of such a little money ...

PS. If you buy or do not know what kind of power supply,
Then directly to buy the 80plus Rhine SeaSonic have S12II series like ...
(General user S12II buy the 330W it good enough for us.)

PS. Abroad there is a simple Web site devoted to help you calculate your computer wattage power consumption,
General purchasing power supply, as long as the capacity to buy just enough wattage,
Do not need money to buy big hit wattage of ...
http://www.jscustompcs.com/power_supply/

PS. I have another one on the power-saving light bulbs and traditional light bulb tariff differences, we can go take a look at the time.
It is because energy saving light bulb energy conversion efficiency better than traditional light bulbs,
Therefore, we recommend that you go to a very traditional home energy saving light bulbs replaced all light bulbs,
Simple actions can save a lot of money!
(Environmental protection is followed by you, anyway, that's nothing to us with other people's children to die ...)

[PC] computer wattage consumption of electricity and energy calculation program

I. Computer chassis power consumption estimates:

CPU: AMD about 49w ~ 89w, Intel about 35w ~ 103w
Motherboard: 25w
Memory RAM: each SDRAM about 12w, DDR about 10w, DDR2 about 7.5W
Display card: About 30w ~ 77w

Hard disk: 25w
CD-ROM: DVD RW about 25w
Floppy disk: 5w

Fan: 2w (LED fan 3w)
Keyboard and Mouse: 3w
USB interface device: 5w
PCI adapter: 5w
1394: 8w

These are the computer chassis parts each about the loss of power wattage,

I assume that the estimated CPU 70w, VGA display card 55w, memory 10w * 2, the internal fan has two, USB interface 1,
Well, most people are using non-screen computer chassis pure power consumption should be:
70 + 25 +10 * 2 + 55 + 25 + 25 + 5 + 2 * 2 +3 + 5 = 237w

(Want to know how many computers actually Watt watt, please refer to their own components to increase or decrease)

So most people are about power consumption 240w about
Moreover, the value of each part to the maximum power output of the state,
Congress generally does not achieve this maximum,

Ordinary computer users to buy power, it may use less than large wattage (400w or more) of power supply,
Market 300w ~ 350w power supply should be sufficient to meet the ...

II. How to use simple methods to save electricity:

If the network is only hanging by a machine (or BT download dedicated server), no good parts, then
How does the power to save money?

1. From the computer components on the good energy saving measures

For example,
(1) does not require the display card must run very quickly, you can buy a three-in-one motherboard (built-in graphics card),
Can save almost a display card of electricity.

(2) floppy drive does not often used, you can unplug the floppy drive cable and power cord.

(3) CD-ROM drive if it were not for everyday use, it can be converted into an external USB2.0 mode.

2. From the shopping area power supply, energy saving measures to do a good job

Of course, I stress once again that if you want to save money, purchasing power supply (POWER SUPPLY), the
The most important thing is not it better not look good, but its conversion performance (efficiency)!

240w is a computer above the operation of the internal DC power consumption wattage,
In fact the power supply 110v AC DC conversion process, but also wasting a lot of electricity,
This ratio between the conversion is [efficiency].

(1) If your power is old and without Active PFC, only 66 percent conversion efficiency,
Then you actually consumed electricity is: 240w / 66% = 360w
(2) If your power is in line with the 80plus norms 80 percent conversion efficiency,
Then you actually consumed electricity is: 240w / 80% = 300w

Do not underestimate the difference between this 60W, computer hang up if the operation 24 hours a day who
Well, every year more than a waste: 60 * 24 * 365 / 1000 = 525.6 degrees electricity if 1 unit of electricity of about 2.5 yuan calculated, then the loss of 525.6 * 2.5 = 1314 yuan
(Per unit of electricity costs, please refer to their own electricity bills from the most senior of electricity in summer than in winter your electricity)

Fortunately, the actual situation is that the computer would not have been running the maximum power, so electricity would not be such a big gap.

Unfortunately, no accident, then, power is not easily broken, may be able to use 4 to 6 years
This tired by years of tariff gap, may be to your life ...

[PC] people do not want to buy LCD screen three reasons ...

Earlier on, when the thunder still insist on watching cartoons,
The results flash mine at the same time, the screen flashes a little,
After a three-day Taiwan, my 19-inch CTX PR960F In this way the dead ...

Rare that the CRT screen can be opened but 1152 * 864 vertical frequency 120Hz it!
Now use this backup of 17-inch screen, can only open the 1024 * 768 85Hz,
Update frequency is not high enough because of the feeling has been the screen flashes,
See a long time, good sore eyes ...

Really, can continue to use high-end CRT screen, I do not want to go压根with LCD screen,
CRT screen but also the delivery of heavy maintenance is very convenient, but also the power consumption is to eat money,
(More power, I can refer to another article)
Therefore, and CRT is the time to say goodbye ...

However, the results of a few days ago to buy LCD or return eventually, the
Cause I now can only continue to support CRT, it is human tragedy ...

1.LCD is still very much an idiot models do!

To 19-inch LCD is actually divided into two idiots size,
One is the long-screen 5:4, 1280 * 1024
One is the 16:10 widescreen, 1440 * 900

Either way, are an idiot design,
Engage in the kind of nondescript ratio, only the panel think that the convenience of the company read it!
(Early original ratio is 4:3)

To do! You do 4:3, or 16:9 you do!

I have that 19-inch widescreen LCD 16:10 as an example,
Intentionally do not make the kind of natural size, but its built-in default in addition to 1440 * 900 resolution, the
Other built-in default value has been like this son ...
1280 * 1024, 5:4
1024 * 768, 4:3
800 * 600, 4:3

Know what I have to say it?
That is, the 19-inch widescreen LCD you apart from the use of 1440 * 900 is no alternative!
Only that it is in line with the basic screen aspect ratio (16:10),
If you want to set the rate of adoption of the other is waiting for deformation, waiting to see them become fat graphics ...

OH ~ NO ~ ~ ~
Since manufacturers have the courage to design the ratio of 16:10 this strange liquid crystal screen, and
Why not the other built-in wide-screen ratio of 16:10 it all changed?
Changed to: 1280 * 800, 1024 * 640, 800 * 500

In short ah ...
16:10 that was locked only in 1440 * 900 widescreen,
Often only suitable for watching widescreen movies, wide games, or office purposes of users,

Or just look at the habits of Internet 4:3 TV or film is not suitable for human use ...

Regular access to the Internet is the proposed length of person I arrived in 1152 or 1280 as long as it is sufficient
Web design because it is now, the page is still the mainstream in 1024 or the extent of 800,
Spent too long for more than 1440, it will only let you open the page, about a large space,
Screen from top to bottom are too short and often pulled down the page to use the mouse to browse, hands will be very hard ...

Because of these stupid reasons,
Can X also because that company employees with the kind of bad attitude in handling my warranty models without highlights rejected,
Do not want to suffer at that stores, and had no choice but to simply return to a refund!

Until now, I can only use this bad bad CRT screen ...
Hope that it will quickly blow up ...

2. Stupid LCD screen of the second point,
DVI interface that is!

I heard I do not know that consumption stayed DVI interface that is considered home appliances to draw high taxes,
DVI did not count information products do not have the tax deduction so high,
So many LCD screen caused by more than half do not have DVI interface ...

OH ~ NO ~ ~ ~
LCD (digital) can be won CRT (analog) the most important part is the DVI interface ah!
Because the digital data using DVI (digital) interface to pass in order to convey the true digital LCD screen,
Through D-SUB (analog) interface connector, but the deterioration is not it?

Moreover, the display card to buy now, in addition to a dedicated card or poor idiot dedicated brand computers, the
Where to find no DVI output ah?

Whenever see digital LCD screen can actually plug analog D-SUB connectors,
I for the LCD screen deeply sad ...

And, obviously there are now equipped with DVI graphics card, and
However, there are large numbers of only D-SUB interface LCD screen constantly being produced,
To buy a DVI interface have not only have to carefully observe the aircraft, but also your many,
Such harm LCD screen go back off the road, blame the right to impose taxes and harm ...

3. Stupid LCD screen of the third point, that is bright scotoma~ ~ ~

Here I feel very sad that consumers,
Into education has been manufacturers, LCD Youliang scotoma is normal
New buyers get on the defective goods is normal?
And must be super-defective N months for new products in order to highlight?

Just in addition to spend a lot of money to buy non-liang scotoma warranty models outside
Are generally to age 3 ~ 5 bright spot or the center of the region will allow you to barter New!
(The rules are those companies with their own set!)
Moreover, most stores still do not unite so that you test.

Just imagine, happily spent 6,000 ~ 9,000 to buy a LCD screen,
When you get home, a new boot found bright spots or dark spots there, your mind what will happen!?

Close your eye , and continue to use it to three or five years?

You must have replaced the screen a good mood, it will collapse in an instant!

The price of a new LCD screen should make like the drawing of lots for the gods to bless like,
Prayer itself would not draw too many bright spots dark screen,
Or pray themselves a lot of bright spots dark screen directly for New ...?

Or pay more and more money to get a no warranty Liang scotoma models?

In fact, the bright spots dark one-year warranty or three years do not need is also not necessary,
I think we should at least, at least not to allow consumers to get new products on Youliang like dark spots.

This is the heart problems, no one likes to get new aircraft on the defective goods,

New products have been flawed dark points of light,
Direct discount price point, some do not care to sell the company or Internet cafes like.

Most people get the new products are defective, I do not think anyone will not be crazy, and
Believe that the next time that one can not buy bad quality products ...

So, buy a LCD LCD screen, is really to traumatise,
Poor health can not afford to sustain the attack or have heart disease, and they have to pay more attention to ah!

Supplementary Description:
AOC has just been checked and BENQ bright spot is defined as a black screen will be illuminated under the bright spot is the point ...

AOC alleged bright spot for the black screen displayed when the point of view
http://www.worldtech.com.tw/service/index.asp#AOC顯示器亮點保固準則

What is the bright spot BENQ? What is the dark spots?
* In the test document, such as all-black screen will not be called normal luminous bright points.
* In the test document, such as all-white screen will not be called normal luminous point scotoma.

[Shopping experience] do not want to buy CRT and LCD screen tragic experience ...

Recently bought a CRT screen, immediately regret it ... (CRT must buy the whole plane设法找real)

Early use of the CRT screen CTX PR960F, after the last time thunder,
I decided to repair and spent NT. 1,500 ...
However, another almost a year, in my use of more than 10 hours a day continue to take gymnastics, the screen is also finally going to enjoy the age ...
(A total of about 4 and a half years)
A few days ago, the old CRT screen has started flashing, and
I think that may be killed, so immediately set a new screen ready to prepare for war.

The recent auction on the Internet can buy 19-inch CRT screen, the only V licensing G9x fb ...
The day of arrival to send a fitted, not long I immediately felt regret ...

Because this screen is far better than the old screen,
One is the resolution of the differences:
Old screen in 1280 * 960 to achieve 100Hz, the new can only reach 85Hz
Old screen in 1152 * 864 to achieve 120Hz, can only reach new 100Hz

Another difference is the whole plane:
The old screen is a special SONY CRT, really is the whole plane is completely ...
The new screen is appears there will be the middle of expanding the feeling of expansion, this strange sense of really bad ah ...

The old screen CRT CTX PR960F, in 4 years and a half years ago 11,000 to spend money to buy diversified, and
3 spent more than a year, killed one, but also spent 1,500 yuan to maintenance and repair, yet spent almost a year.

[PC] 19-inch CRT screen and LCD screen, the number of tariff difference?

Buy CRT and LCD display screen, price comparisons before
Remember to consider the difference between tariff!

I just find a 19-inch CRT screen, and 19-inch LCD screen,
With the greatest power to compare.

(1) 19-inch CRT monitor power consumption around 125W ~ 130W between
(However, at present there are power-type 80 ~ 100W in the following ...)
The assumption that the 130W, use 10 hours a day, the use of 3 and a half years died!

Well, this 19-inch CRT total power consumption of about:
130 * 10 * 365 * 3.5 = 1660750 = 1660.75 degrees about 2.5 per million, the total electricity = 1660.75 * 2.5 = 4152 dollar

(2) 19-inch LCD screen power consumption of about 32W ~ 40W between
Assumption is 40W, use 10 hours a day, the use of 3 and a half years died!

Well, this 19-inch LCD the total power consumption of about:
40 * 10 * 365 * 3.5 = 511000 = 511 degrees about 2.5 per million, the total electricity = 511 * 2.5 = 1278 yuan

Therefore, the assumption that the same two-screen life is three and a half years (12,775 hours),
So bad is the electricity 4152-1278 = 2874 yuan
