8. 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 .
8

9. Why VLSI?
 Integration improves the design
 Lower parasitic
 higher speed
 Lower power consumption
 Physically smaller
 Integration reduces manufacturing cost

10. VLSI Chip Types
 Full-custom Design
 Application-Specific Integrated Circuits (ASICs)
 Semi-custom Design

Microprocessor
 Microprocessor is include 8085, 8086
 First microprocessor is intel in 4004
 Introduced in 1971

14. 14
PERSONAL COMPUTER
 Personal Computer
 introduced by IBM in 1981
 Made for using computers in home, office and
school

15. 15MULTITASKING
 method where multiple tasks,It is a
 It also known as processes, are performed
during the same period of time.

16. 16Invention of Internet
● The public was the first who introduced the idea of invented
internet
● In 1973, Vinton Cerf developed internet

19. 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

20. Types of 4 GL
 Table-driven (codeless) programming
 Report generators
 Data management 4GLs
20

21. Some fourth-generation languages
 FoxPro
 PowerBuilder
 SQL
 Report Builder
 Graph Talk
 MATLAB
 CSS
21

22. Benefit of 4GL
 All 4GLs are designed to reduce
 programming effort,
 the time it takes to develop software and
 the cost of software development

24. Advantages of 4th Generation Computer 24

25.  More powerful and reliable
 Less hardware failure
 Commercial production
 Less need of repair
 Fast processing power with less power consumption
 Cheapest among all generations
25Advantages of 4th Generation Computer

26. Disadvantages of 4th Generation Computer
 Easily get virus
 Only Highly skilled staff can manufacturing
 The microprocessor use very high sophisticated technology.
26

27. 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.
