File Name: advantages and disadvantages of generation of computer .zip
When we study the history of the computer, it is concluded that based on the characteristics of various computers developed from time to time, they are categories in five generations of computer. First generation computer was designed during — They were constructed by using Vacuum Tube, which was a glass tube , capable to manage and amplify the electronic signals. In , three scientists developed transistor in Bell Laboratories. These scientists include J.
Vacuum tubes were used to perform logic operations and to store data. It is developed using massively parallel computing. Computers are an integral part of our life. The first generation of computers used vacuum tubes as their circuitry and magnetic drums as the memory to save data. The first generation of computers used vacuum tubes as a major piece of technology. The input of this system was based on punched cards and paper tape; however, the output was displayed on printouts. This period, during which the evaluation of computers took place, cab be divided into five distinct phases known as generations of computers.
There are many advantages to using a computer. Below is given a list that contains the main advantages of computers. Computers help increase user productivity, and users become more productive at everything you do on the software running on the computer with a good understanding. For instance, when you have work on an Excel worksheet with a basic understanding, you can create, edit, delete, store, calculation, and print documents and letters. With all pre-existing technologies, all of these things were either impossible or much slower.
A computer is a machine that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming. Modern computers have the ability to follow generalized sets of operations, called programs. These programs enable computers to perform an extremely wide range of tasks. A "complete" computer including the hardware , the operating system main software , and peripheral equipment required and used for "full" operation can be referred to as a computer system.
The third generation of computers used integrated circuits instead of transistors technology that was used in computers of second-generation. Its time period was around to An integrated circuit is a small chip that was the trademark of the computers of third generation. The integrated circuit used in 3rd generation computers can work as computer memory, microprocessor or even an amplifier. The first to develop the idea of the integrated circuit was Robert Noyce of Fairchild Semiconductor and Jack Kilby American electrical engineer of Texas Instruments in
Information Communication Technologies ICT is the combination of computer-based technologies such as computing devices and smartphones with communication technologies such as telephones, cell phones and the internet. In practice, it refers to all the hardware, software, and systems essential to communicate electronically. Over the last twenty years, the field of ICT has grown from a small niche field to one of the most important fields in the world.
