The blog I created is all about the computer and the parts of it. This blog consists the basic parts of the computer, which is the Computer case or the computer chassis and the units inside it, monitor, keyboard, mouse, and speakers. All of it will be discussed according how I said it.
THE PARTS OF COMPUTER AND THEIR USE
I. COMPUTER CASE/SYSTEM UNIT AND PARTS
The computer case contains the most important components of the computer: the motherboard, the processor, random access memory modules, the hard drive etc. It may not be possible to exchange the components in a laptop computer, but in a desktop computer you have much more influence on the parts inside the case.
1. The Motherboard
The motherboard is the part of the computer where such things as the processor, memory modules, expansion cards and external devices are attached. This means that the motherboard controls the functions of different components. The number of connection slots for peripheral devices and the number and type of memory slots are important properties of the motherboard.
In addition to the various connections, the motherboard also has a small battery ensuring that settings made on the board are retained even when the computer is switched off.
2. CPU (Central Processing Unit)
The processor can be considered to be the ‘engine’ of the computer because it executes the lion’s share of the information processing; the processor fetches commands and necessary information from the RAM, carries out the tasks specified by the commands, and returns the processed information to the RAM.
The speed of a computer depends largely on the speed of the processor. The processor’s speed, in turn, is affected by various factors, such as the so-called clock frequency (usually expressed as gigahertz, GHz), the amount of cores and of the so-called cache memory inside the processor.
3. RAM (Random Access Memory)
The RAM (Random Access Memory) is a memory storage that functions during computer use and is especially utilized by the processor. In modern computers, the amount of RAM is around 4 – 16 GB depending on the type and purpose of the computer. The RAM consists of one or more memory modules.
When the computer is started, the operating system is loaded into the RAM (an operating system is a program that controls the devices and programs in a computer). The computer also loads the files being processed – music, assignments, videos etc – to the RAM.
If there is enough RAM, the computer executes requested tasks quickly. This is why it is a good idea to add to the memory by buying more memory modules as the need arises.
4. HARD DRIVE
The hard drive is the permanent memory of the computer where saved files remain even when the computer is turned off. This is why the hard drive is used for saving files.
The capacity of hard drives varies; currently the typical capacity is 500-1000 GB, but hard drives of over 1500 GB, i.e. 1.5 terabit, are also available. However, the capacity of the internal hard drives in laptop computers is often less than that.You can add to the capacity of your computer by attaching an additional hard drive, either internally or externally.
The hard disk is used for the storage of the computer’s operating system and all important files. It is therefore packed in a fixed protective housing. The disks may become damaged in spite of this protection, so you should absolutely make backup copies of files on the hard drive from time to time.
Computer speakers are speakers sold for use with computers, although usually capable of other audio uses, e.g. for an MP3 Player.
