Before buying a computer, find out:

 It goes without saying that the computer is the greatest device of modern technology. So everyone wants to buy a computer. But to buy a good computer you need to know some things about computers. I will tell you something like that today. I tried to write the post in simple words keeping in mind the people who are completely new to computers.

Here are a few things to keep in mind when buying a computer:

1. What kind of customer service does the store offer to the buyers? Acquaintances can help in this case.

2. Open hardware is often available in the market. Never buy these.

3. If you are not a computer expert, at least buy Processor, Mainboard, RAM, HDD, ODD, Graphics Card, Casing from the same store. They will configure them properly.

Now I will talk about each of the core parts of the computer and what to look for when buying them.

Cess Processor:

The main thing in computers. This is what the computer does all the work. This is basically called CPU (Central Processing Unit). The most popular processor manufacturers are Intel and AMD (Advanced Micro Device). Both are good, but the most popular and technologically advanced is Intel.

Since the processor is the most important, special care must be taken when buying it.

1. You have to notice the clock speed of the processor. The higher the clock speed, the higher the processing power of the processor.

2. What is the series of processors, it must be noticed. The better the series, the faster the speed. Intel's earliest processors include the Pentium Series. Next came the series, Celeron series, Core Series, i Series. In Pentium Series, P2 is better than P1 (Pentium 1), P3 is better than P2 and P4 is better than P3. That is, the speed of P2 is higher than that of P1 of the same clock speed. Again, similarly, the Core Series has a higher speed than the Pentium Series. Among the processors in the core series, Core 2 Quad> Core 2 Duo> Dual Core. Among the processors of core I series, Core i7 extreme> Core i7> Core i5> Core i3.

3. You have to notice how many cores and how many threads there are in the processor. The higher the number of cores and threads, the faster the speed. So far a maximum of six-core processors has been discovered.

4. The amount of FSB (Front Serial Bus) should be noticed. The higher the FSB, the higher the speed. Although newer processors do not use FSB. QPI is used instead.

5. Cache Memory, you have to notice. There are different types of cache memory. The latest technology cache memory is L3 Cache.

. Make sure you have Hyper-Threading Technology. This technology plays an effective role in multitasking.

. In the case of Intel Processor, make sure that there is Turbo Boost Technology. This technology increases the capacity of the processor when needed.

. See if there is a GPU (Graphics Processing Unit). External Graphics Card is not required if the processor has a GPU and uses a good motherboard. (Unless you play a very high-quality game on a computer or do graphics designing or HD video editing etc.)

[Processors with the last three options usually cost more. All of these options are not required for normal operation.]

Mainboard or Motherboard (Mainboard or Motherboard):

This board contains all the components of the computer. The best brands for the mainboard are Gigabyte, Intel, Foxconn, Asus, etc. The motherboard must be processor supported. There are two types of mainboard ports, IDE and S-ATA. However, the mainboard of the S-ATA port is currently visible. Almost all S-ATA ports have at least one IDE port on the mainboard. If necessary, the IDE device can be used on the mainboard of the S-ATA port by using IDE to S-ATA converter. The things to keep in mind when buying a motherboard are:

1. The motherboard seems to support the processor.

2. Type of RAM. You have to buy the same type of RAM as the RAM slot on the mainboard. The latest RAM type is DDR3.

3. What is the version of the USB Port? The latest is USB 3.0. [Motherboard with USB 3.0 port costs a bit more]

4. Currently all mainboards have LAN Card (Local Area Network Card). Moreover, HD audio and HD video can also be noticed. The higher the value of integrated graphics, the better.

➤ Monitor:

This is the main output of the computer. Good brands for monitors are Samsung, Philips, LG, Asus, HP, Fujitsu, etc. Here are the things to keep in mind when buying a monitor:

In case of LCD (Liquid Crystal Display) / LED (Light Emitting Diode) Monitor:

1. Select the screen size according to your needs. Many monitors now have a built-in TV tuner. At the same time, these will work as computer monitors and TVs. If you do not have a TV Tuner, you can buy a separate TV Tuner if needed.

2. LCD monitors are of two types, square and widescreen. You will select it according to the need of your cause.

3. The difference between LCD and LED monitor is: the LED monitor is an advanced type of LCD monitor. Relatively good pictures can be seen on the LED monitor. Moreover, it is comfortable to look at the LED monitor.

4. Notice the Contrast Ratio. The higher it is, the better the image quality
