What did the old computer look like, and what was the name of that old computer? The great god came

Transistor computers were oversized and the world's first computer in 1964.

CRT display, is the screen of the display tube electronic technology, in the past, the Great Wall's big-head machine did very well, in the 90s can be said to be a hegemon.

That kind of display is actually more stable than LCD, but because of the large radiation, high power consumption, so it was eliminated, the current LCD screen has advantages in power consumption and radiation convenience, and it is light and convenient, naturally replacing the big head machine, but in fact, in a sense, in fact, such as drawing CAD, the big head machine is more applicable, and there are still quite a few people like it. That screen flickered, also because it was flat, at the time it was CRT technology. CRT is a display that uses a cathode ray tube and consists of five main parts:

Electron gun, deflection

coils), shadow

mask), phosphor and glass shell. It used to be one of the most widely used displays, CRT flat screen displays have the advantages of large viewing angles, no dead pixels, high color reproduction, uniform chromaticity, adjustable multi-resolution mode, and short response time. I answered very seriously.,It's definitely not a copy and paste.,I'm doing this.,University is also learning electronic technology.,If you need help, please harass.。

The owner of the watchtower compares carefully, and then adopts and gives points.

Flat screen display.

Does the screen flicker?

It is thought to work by an electron gun in a picture tube that shoots a beam of light through a small hole in the shadow mask and hits a layer of phosphor coated with countless primary colors of inner glass.

Unstable performance.

Things are getting more and more advanced as they develop, and they don't go back.

The display screen is very long and fat (we call him a big head machine), you should be talking about the CRT display, because it is progressive scan imaging, unlike the liquid crystal is a static display all will flash, the technology is constantly improving, all liquid crystals have replaced the CRT technology.

Are you a desktop? The current monitors are all LCD, and of course they don't flicker.

That kind of screen is a picture tube display,Like a TV,Flicker is to prevent damage to the eyes、Myopia,And that's the display tube can't keep up with the imaging speed,Very professionally speaking,It's the time difference between the speed of the human eye and the imaging speed,TV is the same、It's just that the time difference is short,Can't see it,And the current display is three tubes、Transistor、Just like the replacement of TV,You take a closer look,You can see that the screen of the color TV is a small grid one by one。

It's called CRT Reality, and the screen flickers because its refresh rate is too low. Compared with the current LCD display, it is medium in weight, large in size, and consumes energy.

Of course, the main thing is that there is a lot of radiation due to the use of cathode ray tubes. So it was eliminated! But you need to be told that the display effect of the LCD display is not as good as the display effect of the CRT!

Please ask the questioner to pay attention to the old bird of hand-coded words, thank you! Copying is disrespectful to the questioner!

A CRT monitor is a display that uses a cathode ray tube, which is mainly composed of five parts: electron gun, deflection coils, shadow mask, high-pressure graphite electrode and phosphor coating and glass housing. It is one of the most widely used monitors at present, CRT flat screen display has a large viewing angle, no dead pixels, high color reproduction, uniform chromaticity, adjustable multi-resolution mode, extremely short response time and other advantages that LCD displays are difficult to exceed, and now CRT monitors are much cheaper than LCD displays. Reference.

This configuration is actually okay, it is enough for ordinary home or ordinary office, and you can also play small and medium-sized games such as LOL, DNF, CF. It's better to add a 4G memory.

If you want to play big games, you need to upgrade your CPU and graphics card, add memory.

The processor can use i7 4770 or E3 1231 v3, and the graphics card can use GTX1060 6G; Memory can be used with two 8G DDR3 1600.

This configuration is no problem for general home online classes and office work,It's OK to play games that don't require much,If it's a whole machine upgrade,Then only the solid-state drive and GT730 can be used,GT730The performance is not high, it belongs to the bright machine card,But now the graphics card is too expensive,And it must be valuable。

The whole machine can also be used,If you plan to install a new machine, you want to save some of the original basic impossibility,The most important thing for the assembly machine is that it should be compatible together.,You can't change the memory to a big one, and it's equipped with an original small graphics card or something.。

This machine is simple for office use and gaming.

If there is no problem with the computer, you can continue to use it. There is nothing wrong with this configuration for ordinary office use.

A computer a long time ago,I want to ask which of the following configurations can be used,If you pursue a low one,Add an 8G memory on it。 The graphics card is a bit poor, but there is no problem with playing lol smoothly with minimal special effects.

Hard drives, monitors, and graphics cards can continue to be used.

In fact, your computer is still very easy to use under the upgrade.

CPU: Swap to i5 4460, i7 4790, i7 4790K RAM: Upgrade to 8G

Graphics card: Change to a stronger one, such as GTX 750TI, GTX 760, GTX 960, GTX 970 (maybe the power supply will also be changed).

If you want to upgrade the computer, as long as the motherboard is replaced, then there are more things to replace, such as the motherboard CPU memory module, all need to be replaced, of course, your graphics card is not good, it is best to replace it together, the rest of the things can be used, but it mainly depends on personal needs, in fact, the overall situation of your old computer is not bad, add a memory, change a graphics card, play some slightly larger games, or it should be very good.

If there is no problem with the computer, continue to use it well, if you change to a new computer, the monitor will not be too old, and continue to use it, the host computer is relatively backward for the current mainstream computer.

As long as the computer can run normally, I think the hard disk can continue to be used, and the configuration of the computer can refer to the detection data of Master Xialu.

Upgrade the graphics card, add a memory, and you can top it for three or five years.

SSDs and monitors are definitely here to stay.

Other accessories will be upgraded or replaced entirely, depending on the situation.

It depends on your needs. If the requirements are not high, upgrade them, and if you want to play super-large games, replace them all.

If you upgrade, if you change the CPU to an i7 4770 or 4790, you can also consider Xeon E3 1230 v3. Memory module plus an 8G one. GTX 1060 or 1070 on graphics card.

It's only second-hand, it shouldn't be very expensive, and you can play most online games.

The configuration is already considered high, and it can be used. FYI.

The first computer was called Eniake and it used 18,800 vacuum tubes, 50 feet long, 30 feet wide, 1,500 square feet, and weighed 30 tons (about the size of a classroom and a half, and six elephants). It is fast enough to perform 5,000 additions per second for nine years. It is rumored that every time the ENIAC is turned on, the lights of the entire West Side of Philadelphia are eclipsed.

It was made by man for laziness.
