Computer Generations

 Computer Generations 

 Computers have evolved over time through different generations, each marked by significant technological advancements and changes in design and architecture. These generations are often categorized based on the underlying hardware and the key developments that distinguish one Generation from another. Let's explore the main computer generations:

First Generation Computers 

 The First Generation of computers refers to the initial period of electronic computing, characterized by the use of vacuum tubes as the primary electronic component. This Generation spans the 1940s and 1950s and is marked by groundbreaking developments in computer technology. 
Examples of First-Generation Computers:
 o ENIAC (Electronic Numerical Integrator and Computer): Completed in 1945, ENIAC was one of the first electronic general-purpose computers. It was designed to calculate artillery firing tables for the United States Army during World War II.
 o UNIVAC I (Universal Automatic Computer I): Developed in the early 1950s, UNIVAC I was the first commercial computer in the United States. It was used for business and scientific applications.
Advantages:
 • Pioneering Technology: First-generation computers laid the foundation for modern computing and set the stage for future advancements.
 • Initial Computations: They were used for essential tasks like calculations for military and scientific purposes. 
 Disadvantages:
 • Size and Cost: First-generation computers were massive and expensive to build and maintain.
 • Limited Programmability: Programming involved manual rewiring, making it time-consuming and challenging.
 • Reliability Issues: Vacuum tubes were prone to failures, leading to frequent downtime. 

Second Generation Computers 

 The Second Generation of computers refers to the era of computing from the late 1950s to the mid-1960s. This Generation witnessed significant advancements over the first Generation, primarily due to the replacement of vacuum tubes with transistors as the primary electronic component.

Examples of Second-Generation Computers 

 o IBM 7090: Introduced in 1959, the IBM 7090 was a significant second-generation computer used for scientific and engineering calculations.

 o UNIVAC II: The successor to the UNIVAC I, UNIVAC II was another commercial computer that gained popularity during this Generation.

Computer Basic

  The word “computer” comes from the word “compute”, which means to calculate”. Charles Babbage is known as the ' Father of computer' .  A computer often referred to as a “data processor” because it can store, process, and retrieve data whenever desired.  The activity of processing data using a computer is called data processing.    Data processing consists of three sub activities:- (1)          Capturing input data (2)          Manipulating the data and (3)          Managing output results. Data : - Data is raw material used as input to data processing. Data can be anything like numerical, non-numerical or a mixture of both. Information : - Information is processed data obtained as output of data processing. Computer: - A computer is an electronic device which performs numerical calculation and logical calculation at hig...
