7. Introduction
Very-large-scale integration (VLSI) is the process of creating an IC by combining
thousands of transistors into a single chip.
The microprocessor is a VLSI device.
The microprocessor is the characteristic of fourth generation computers .

18. Fourth Generation Language
A fourth-generation programming language (1970s-1990) (abbreviated
4GL) is a programming language designed with a specific purpose in mind ,
such as the development of commercial business software
Forth-generation languages have often been compared to domain-
specific programming languages (DSLs).

19. Types of 4 GL
Table-driven (codeless) programming
Report generators
Data management 4GLs

21. Benefit of 4GL
All 4GLs are designed to reduce
programming effort,
the time it takes to develop software and
the cost of software development
21
24. More powerful and reliable
Less hardware failure
Commercial production
Less need of repair
Fast processing power with less power consumption
Cheapest among all generations

Advantages of 4th Generation Computer
25. Disadvantages of 4th Generation Computer
Easily get virus
Only Highly skilled staff can manufacturing
The microprocessor use very high sophisticated technology.

26. Disadvantages of 4th Generation Computer
Very advanced technology was required to fabricate to
the ICs.
Very advance technology was required to make the ICs.
Air conditioning was required in many cases due to ICs.
