The technology behind the primary generation computers was a fragile glass device, which was called a vacuum tube. These computers were very heavy and really large. These weren’t very reliable and programming on them was a tedious task as they used low-level programming language and used no OS. First-generation computers were used for calculation, storage, and control purpose. They were too bulky and large that they needed a full room and consumed a lot of electricity. Punch cards were used for improving the information for external storage. Magnetic card used. Machine and assembly language is developed. Examples of some main first-generation computers are mentioned below. ENIAC: Electronic Numerical Integrator and Computer, built by J. Presper Eckert and John V. Mauchly was a general-purpose computer. It had been cumbersome, and large, and contained 18,000 vacuum tubes. EDVAC: Electronic Discrete Variable Automatic Computer was designed by von Neumann. It could store data also as instruction and thus the speed was enhanced. UNIVAC: Universal Automatic Computer was developed in 1952 by Eckert and Mauchly.

Understand the Problem

The text provides an overview of the technology and features of first-generation computers, specifically focusing on their use of vacuum tubes, size, programming challenges, and examples of such computers.

Answer

First-generation computers used vacuum tubes, were bulky and unreliable, and included ENIAC, EDVAC, and UNIVAC.

The first generation of computers utilized vacuum tubes as their main technology. These computers were large, heavy, and unreliable, using machine and assembly languages for programming. Examples include ENIAC, EDVAC, and UNIVAC.

Answer for screen readers

The first generation of computers utilized vacuum tubes as their main technology. These computers were large, heavy, and unreliable, using machine and assembly languages for programming. Examples include ENIAC, EDVAC, and UNIVAC.

More Information

These first generation computers marked the beginning of computing technology, significantly changing data processing but were limited by their massive size and lack of versatility.

Tips

A common mistake is to confuse vacuum tubes with more modern technologies like transistors. It's important to differentiate these technologies and understand their historical context.
