What is a computer – brief history of computers
Do you know what is a computer? Well, a computer is basically a device which is used to perform general purpose functions such as logical and arithmetic operations of any complexity and length within the matter of a few seconds. The computer is a highly versatile machine, and hence, it can be used to solve a different kind of problems.
The basic parts of a computer include the central processing unit, also known as the brain of the computer, a form of memory and is accompanied by some other peripheral devices such as the monitor which is used for display purpose and the keyboard which is used as an input device. In a nutshell, if you want to know what is computer! It is a machine which can be used to solve difficult and complex problems in a very short time.
When was the first computer made?
Do you know who founded the computer? The first mechanical computer was invented by Charles Babbage in the early years of the 19th century and hence is rightfully known as the father of the computer.
Brief history of computer
The history of computer dates back dates back to the year 1936 when it was first invented by Konrad Zuse and was known as the Z1 computer. This was the first ever programmable computer and hence with its new computing power, it was set apart from all other machines.
However even though this was a breakthrough invention, there was no major prospect of computers in the world of business at least not until the year 1942. In this remarkable year, John Vincent Atanasoff and Clifford Berry started the first ever company for computers, known as the ABC computers. After a year or two, another computer was developed, which was much more advanced. This computer was the Harvard Mark I computer.
What are the basic computer types?
There are four broad types of computer. They are:
- Supercomputer: this is the most advanced type of computer and in better in terms of everything including data processing and performance.
- Mainframe computer: this is not as superior as the super computer but is a definite improvement over its previous type. They are expensive and preferably used to run business operations.
- Minicomputer: better and advanced over the microcomputer.
- Microcomputer: the most basic type of computer.
