Basic Knowledge In Computer Configuration You Need To Know
Computers usually consist of the following devices:
The central processing unit ( CPU, Central Processing Unit)
There aren’t many people who call it a “central processing unit” in Japanese. CPU is normal. A device that processes data.
The main storage device ( Main Memory )
A device that stores data. It is used to memorize the program being executed and to store the data necessary for the program to work. This is also katakana and is often called main memory.
The auxiliary storage device (auxiliary memory)
A device that stores data. Operating speed is slower than main memory. The usual usage is to store data permanently. Files are usually saved here. I don’t say “auxiliary memory” in katakana because it’s difficult to pronounce.
The input device (input device)
A device for giving data and instructions to a computer.
Output device (output device)
A device for retrieving data from a computer and displaying processing results.
Inputs and outputs are often referred to as input/output, and the term input/output device is often used to combine input devices and output devices. Input/output is shortly called I / O in English (a word that comes from Input / Output). There are often devices that double as input devices and output devices. The main storage device and various auxiliary storage devices are collectively called storage devices. The main memory device, current, silicon (silicon, elemental symbols Si, a typical semiconductor such) a is produced as the main raw material a semiconductor memory which is called an (especially RAM to use a what is called) Average. More on that later. Auxiliary storage devices include hard disks and floppy disks. This will be explained in detail later. A typical example of an input device is a keyboard and a mouse. Typical examples of output devices include displays (various types) and printers. There are other devices for communicating with other computers, but this can also be seen as a type of input/output device. (It is not the human being who inputs and receives the data, but the computer to which it is connected.) However, the communication device may be considered independently.
Five major computers
Previously-mentioned CPU, storage device, input device, in addition to an output device may as a component of a computer control device, but is listed in the figure above, the control device is contained within the CPU and each interface It does not appear on the surface because it is present. In addition, there is a document that includes an arithmetic unit as a component, but it is contained in the CPU and executes four arithmetic operations and logical operations. Since some parts of the CPU are in control, it can be roughly considered that the CPU is made up of a control unit and an arithmetic unit. Often, they are classified into five categories: control devices, arithmetic devices, storage devices, input devices, and output devices, and these are called the five major devices of calculators.
ROM is a word derived from Read-Only Memory and is read as “ROM”. A ROM is a storage element that can read the data recorded in it but cannot write new data (rewrite the written data) to it. (I’ll see later on what to use it for.) Then, when to put the contents, the data is written at the time of manufacturing the ROM. The stored contents of the ROM are not erased even when the power is turned off.
RAM is a word derived from Random Access Memory and is read as “ram”. RAM usually occupies most of the main memory. It has the feature of ” random access ” and the feature of ” reading and writing at any time “.
A little IC story
In the old days, the only way to build an electronic circuit was to connect many parts with wires. The cost was very high as the number of parts increased. However, the semiconductor thin piece ( chip ( Chip numerous to hereinafter)) device method of incorporating is an invention, the situation was completely changed. A circuit made in this way is called an integrated circuit ( IC ). (Elements: basic electronic components, resistors, capacitors, transistors, etc.) Semiconductors have properties intermediate between conductors and insulators. That is, it is not as easy to conduct electricity as a conductor such as metal, but it is not an insulator. Silicon (silicon, element symbol is Si ) is usually used as a semiconductor material. You also need a sharpener like knivsliper to sharpen your tools.
Things to consider when buying Computer hardware
Get to know the hardware you want to buy.
Get an idea of how your new computer is working so you won’t regret what you bought once you’ve got your new computer up and running. This takes some effort, but it teaches you how powerful hardware really is, and better to regret it later.
First, determine the speed and the cores you will need to get the job done. To understand how speed affects multiple cores, calculating clock speed in multi-core processors has some detailed explanations of how you should really look at it.
Memory primarily has something to do with size, since a small size will overload the hard drive when memory is running low. You should avoid this. When you have enough size, you can take a closer look at the speed of the memory. However, be sure to buy the right type of memory your motherboard can handle.
Given that hard drive technologies are changing nowadays, it can be confusing and frustrating at times when looking for storage. Since this is where all of your applications and data is stored, it is important to understand one of the most important hardware components. Make sure this is completely suitable for your purposes and has the options that you may or may not need.
The motherboard ties it all up, which means you need to make sure everything fits first, and possibly some extra functionality for later cards and external hardware. Make sure it has the correct socket for your processor, what type of RAM it supports, how many PCI slots, USB ports, LAN, audio, possibly integrated graphics, etc.
Your case should be fairly simple as it won’t interfere with your computer use a little. Unless you intend to present your computer at a LAN party or the like, it should not be absolutely necessary to fall back on a special place case. Unless the case really doesn’t suit your room.
Last but not least, you need to provide power to your computer. And you want to make sure that something happens when you press the power button, that your computer won’t accidentally restart or, in the worst case, damage your other hardware.
First and foremost, it is important that the power adapter supports the performance of your computer hardware. Look at a power calculator or summarize all of the wattages listed in the technical specifications. Then look for a power supply that supports that wattage. Better higher than lower than performance. Then check that there are enough power supply connections and that they are compatible with the motherboard. Other aspects are the ratings, the quality and the safety. but overall you should be fine if you make sure that you are not looking for poor quality.
Compare hardware quality and prices.
Better to compare different hardware products and pick the best quality / price like ‘hiyahiya‘ than going through the first few things and finding a poor quality computer that cost you a lot.
Check, buy and assemble
Make sure to check that the components fit on the motherboard, check the specs!
