What Is Computer

Computers are an integral part of every part of human life. A computer in itself is a broad term. It contains various concepts, terms and terminology. To understand a computer, it is necessary to understand every component and its terminology. In this article, we will look at the most basic computer terminology.

CPU means ‘Central Processing Unit’. This is the location of computer data handling. In addition, it performs all data manipulation, computation and data formatting for output. Therefore, whenever one buys a computer one becomes more conscious about the CPU and its capabilities.

Execution of instructions within a computer system is very fast. It measures this in a cycle of time and refers to it as megahertz. This is why the ‘table’ of a computer’s processor is sometimes referred to as the clock speed. Think of the CPU (and aligned circuitry) as a heartbeat, this pulsing / beating is expressed as “MHz”. 2000MHz.

Your computer’s hard disk drive is like an audio CD that you keep at home — except that your computer can read and write it. In other words, your computer can take data from your hard drive (to process it into CPU or to put it in RAM).

Also, it can record the results of work returned to the disk that is “writing to disk”. The abbreviation HDD stands for “Hard Disk Drive”.

If you open your HDD, you will get a pancake stack on a two-sided disk.

You can also read and write data to a floppy disk. Simply, it is smaller than an HDD and portable — you can take it to another computer and read from there as well. Floppy disks are sometimes called “secondary storage devices”. They were originally known as ‘floppies’ because they were 5 in inches in width and floppy. They could carry around 720kb of data. Today, although floppy disks are small, rigid, and can carry more data like 1.44Mb.

Hardware is a reference to all physical parts in a computer system. It has monitor, keyboard, mouse, main case which stores RAM, CPU and motherboard.

‘Software’ is a term that refers to the instructions required for a computer to work. It is abstract in nature. Software is also known as “program”. Also, it is a group of computer files, which are used to perform various actions on a computer. You can have a program for ‘word processing’. The software can be transferred to a compact disk and a floppy disk, but usually, sits on a hard drive on a computer waiting to be “run”.
