⏣ What is a Computer ?
- An electronic device that accepts data and processes it into useful information is called a Computer.
⁕ There are two main aspects of the Computer :
▪ Input : The data we enter into the computer is called the input. Input, basically are raw facts for which we want the system to process and give us an outcome.
▪ Output : The answer that the computer provides in return of the raw data entered, is called output.
⏣ Types of Computer :
- There are majorly 4 types of computers which have been described briefly below.
❖ Super Computer – The computers which are used to process a huge amount of data at once are called Supercomputers. They are mostly used in scientific and engineering operations where the processing is complex. They are expensive and complicated to work. For example – The computers used by NASA to launch space shuttles.
❖ Mainframe Computer – Computers designed to be used in large firms and organisations where a lot of people have to work on the same database are called mainframe computers. They are almost equally as expensive as Supercomputers and are the fastest working computers at present. They are mostly used in Banks.
❖ Workstation – Usually a single user system is called a work station. The RAM for such systems is more, and the processors are quite fast. They are mostly used by an individual and can be used for multiple purposes.
❖ Microcomputer – Designed for personal use only. This type of computers can easily be moved from one place to the other. They have a personal storage area, input & output unit and a Central Processing Unit. Examples for microcomputer are desktop, laptop, mobile phone, tables, etc.
