Basic Computer Terminologies


1. CPU :

CPU means ‘Central Processing Unit’. This is the place of computer data handling. Moreover, it does all the data manipulation, calculations and formatting data for output. Hence, whenever someone buys a computer he/she becomes more aware of the CPU and its ability.

The execution of the instructions within the computer system is very fast. It measures it in cycles of time and refers it to as megahertz. That’s why the ‘Mhz’ of a computer’s processor is sometimes mentioned to as the clock speed. Think about CPUs beating like a heart, this pulsing/beating is expressed as “MHz” e.g. 2000Mhz.

2. RAM :

Specifically, RAM stands for “Random Access Memory” or “Ready Access Memory”. It is a temporary notepad where your computer delivers information to the disk, or to the storage place of instructions from other input devices. The term “random access” determines that memory locations in RAM are accessible in any order unlike the continuous approach of a data cassette tape.

3. Hard-disk Drive :

Your computer's hard disk drive is such as an audio CD that you possess at home – except your computer can read and write to it. In other words, your computer can take data from your hard drive.

Also, it can record the results of the work it does back to the disk, which is writing to disk. The abbreviation HDD stands for the hard disk drive.

If you open your HDD, you would find a pancake stack on double-sided disks.

4. Floppy Disk :

You can also read and write data in a floppy disk. Simply, it is smaller than the HDD and portable – you can take it to another computer and read from it there too. Floppy disks are sometimes called “secondary storage devices”. They were known as ‘floppy’ originally because they were 5¼ inches in width and floppy. They could carry almost 720kb of data. Today, however, floppy disks are smaller, rigid, and can carry more data like 1.44Mb.

5. Hardware :

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

6. Software :

‘Software’ is a term that refers to the instructions needed to make a computer work. It is intangible in nature. The software is also known as a “program”. Also, it is a set of computer files that are used to execute different actions on the computer. You can have a program for ‘word processing’. The software can be transferred to a compact disk and floppy disks, but usually, sit on the computer's hard drive waiting to be “run”.
