Top 13 Differences Between Third and fourth Generation of Computers


The computer is electronic and can perform arithmetical and logical operations at high speed with incredible accuracy. The computer system was generally used for calculation purposes. In this article, we will learn the Differences Between Third and fourth Generation of Computers with their characteristics, features, examples, and images.

What is the Third Generation of Computers?

The 3rd generation of computers was developed in 1964 – 1971. 

These generations of computers were far more advanced than their counterparts as they used and utilized Integrated Circuit IC as their main component.

The IC was advanced technology at that time and therefore increased speed and efficiency, outsmarting the other computers in the market.

The 3rd generation computers were faster, smarter, and user friendly compared to second-generation computers.

The Integrated Circuit was invented by Jack Kilby, an electrical engineer from Texas Instrument Company, on 12th September 1958.

The invention of IC was a stepping stone toward the further development of the computer system.

The integrated circuit made computers small in shape and size, eventually making them portable compared to other generation computers.

They produced less heat and energy; also, their electric consumption was pretty low.

This generation of computers extensively used operating systems also utilized high-level programming languages like COBOL and FORTRAN.

What is the Fourth Generation of Computers?

The fourth generation of computers was designed and developed from [1971 - 1985].

They used microprocessors as their main component and installed them in their circuit, which enhanced the overall performance like speed, accuracy, efficiency, and reliability.

The microprocessor increased the computer’s speed, making them multitask, and multiprogramming eventually increased the overall performance.

These qualities made 4th gen computers rule the computer industry for decades.

These generations of the computer used high-level technology like VLSI [Very Large Scale Integration].

Using microprocessors, microcomputers were developed, which were later termed “Personal Computers.”

They are highly portable and can quickly transfer from one location to another.

These 4th generations of computers were more reliable and user-friendly than other generations.

The first personal computer was designed and developed by IBM Company in 1974. They also used high-level programming languages like C, C++, Visual Basic, Python, and SQL Servers.

In 1984 APPLE designed and developed a computer named Macintosh and an operating system for better usability.

They also used input and output devices like mouse, printers, and keyboards for better performance.

They can also perform arithmetic and logical operation with high speed and incredible accuracy.

Computer 4th generations used object-oriented programming, and these techniques are used and utilized in JAVA, PHP, PYTHON, .NET, and Visual Basic.

Fourth-generation computers are used in data management, report generation, software development, GUI development, web development, and research.
