VLSI technology based Computers

The fourth generation computers used the microprocessor, the expanded version of the third computer generation. These computers employed VLSI circuitry and the period from 1971 to 1980 constituted this generation. A microprocessor is used to cram millions of transistors on a single chip, using VLSI and LSI technologies. Very broad integration VLSI is short, while LSI stands for large integration. Large-scale integration.

In contemporary times, computer performance and memory have significantly improved, while costs and size have fallen dramatically.Computers are increasingly popular in this age since they are sold at the lowest price. In addition, due of the capabilities of these fourth generation computers, the personal computer revolution has also been created.

Main components of VLSI Computers

In this part of the article the main components of the VLSI technology based computers will be discussed. The component that we are going to discuss combined together to construct a VLSI based computer. These are five separate components. The fourth generation computers contain input, arithmetic and logic, memory, output and control units. The graphic below shows the computer’s actual position in your computer. Users utilize input devices such as mouse, keyboards, and microphones and so on to enter the unit (a unit is a digital information). On the basis of the instructions, the input is processed or maintained.

Some Characteristics of VLSI based Computers

These computers are equipped with a VLSI circuit which includes millions of transistors. Compared to the previous three generations of computers, the fourth generation is lower in price. The single-board and single-chip processors were created. In terms of speed, accuracy and dependability these computers have improved. Because of the great density of the components, compared with earlier generations, they were tiny in size.

Several high-level languages in the fourth generation. In addition, due to the features of the fourth generation computers, the personal computer revolution was also evolved. Thanks to these computers, the usage of data communication was ubiquitous. In the fourth generation computers the development of networking between the systems started.

Advantages of VLSI based Computers

Due to the increasing component density, the size of the fourth generation computers reduced. The creation of these computers was designed for broad usage. They are more dependable, and these computers’ heat emission is insignificant. In many situations, computers manufactured in the fourth generation require no air condition. These computers must be kept to a minimum of cost and maintenance.

Compared to prior models, these VLSI-based computers were portable. With regard to speed, the VLSI-based computers were significantly quicker across all generations. PCs became increasingly frequent and inexpensive during this era. The aim of the creation of such computers was to produce commercially. All types of high-level languages may be utilized as input on these VLSI-based computers.

Disadvantages of VLSI based Computers

The production of computers based on VLSI chips required advanced technology. These computers were very advanced. You needed a small fan for the system to cool. High technical expertise was also required in the manufacture of microprocessors. High-quality and dependable system or technology can be used for the production of VLSI based ICs.
