Fourth Generation of Computers

Welcome to class!

In today’s class we shall be talking about the four generations of computers. Please enjoy the class!

The fourth generation of computers (1971-1980) was marked by the introduction of Very Large Scale Integration (VLSI) circuits. VLSI technology allowed for the integration of thousands of transistors onto a single chip, leading to smaller, faster, and more affordable computers. This generation of computers also saw the rise of personal computers (PCs), which brought computing power to the masses.

Characteristics of Fourth Generation Computers

Fourth Generation of Computers

  1. Use of VLSI circuits: VLSI technology enabled the integration of thousands of transistors onto a single chip, leading to smaller, faster, and more affordable computers.
  2. Development of microprocessors: Microprocessors are small, integrated circuits that contain all the essential components of a computer’s central processing unit (CPU). Intel’s 4004 microprocessor, released in 1971, was the first commercially available microprocessor.
  3. Introduction of personal computers (PCs): PCs are computers designed for individual users. Apple II, introduced in 1977, was one of the first mass-produced PCs.
  4. Rise of networking: Networking technology allows computers to communicate with each other. The development of networking standards, such as TCP/IP, facilitated the growth of the internet.

Impact of Fourth Generation Computers

The fourth generation of computers had a profound impact on society. PCs brought computing power to the masses, making it possible for individuals to use computers for personal and professional purposes. Networking technology enabled the sharing of information and resources across distances, leading to the growth of the internet and the global economy.

Examples of Fourth Generation Computers Includes;

  1.  Apple II (1977)
  2.  Commodore PET (1977)
  3.  TRS-80 Model I (1977)
  4.  IBM Personal Computer (PC) (1981)
  5.  Apple Macintosh (1984)

In conclusion, the fourth generation of computers revolutionized computing by introducing VLSI technology, microprocessors, and personal computers. These advancements made computers smaller, faster, more affordable, and accessible to a wider range of users. The impact of this generation of computers is still felt today, as the internet and personal computing continue to shape our lives.
