Many major and minor Bank Exams, like SBI Clerk\/PO\/RRB Clerk\/PO<\/a><\/strong> and many others, entertain a Computer Awareness or Knowledge section in addition to other sections, because of the importance of computers in the daily workings of the Banks. Scoring maximum marks in the Computer Knowledge section is comparatively easier than other sections like Reasoning & QA. The best way to score full marks in this section, apart from completing the syllabus is by learning all the terms and basic definitions of Computers.<\/p>\n\n\n\n

In this article we will be focusing on History of computers, which is very important topic from the point of view of all the competitive exams including the Bank Exams that consists of a Computer Awareness section.<\/p>\n\n\n\n

History of Computers<\/h2>\n\n\n\n

Before delving into the complex terms of computers, one must know about the history of computers. Charles Babbage, known as the father of the present-day computers, designed an Analytical Engine which was a general computer. Let us know how the modern-day computer has evolved over the years.<\/p>\n\n\n\n

Today, our modern-day conventional computers consist of at least one processing element, typically a central processing unit (CPU) as a microprocessor, coupled with a computer memory. The processing element carries out arithmetic and logical operations, and a sequencing and control unit can change the order of operations in response to stored information.<\/p>\n\n\n\n

But the computers were very different from ours a hundred, or even two hundred years ago. Let us know the information behind its evolution!<\/p>\n\n\n\n

History of Computers Generation<\/h2>\n\n\n\n

In 16th century, the word \u2018computer\u2019 was first used in for a person who used to compute or do calculations. This word was also in use in the same sense as a noun until the 20th century. Professionals, especially women were hired as human computers to carry out all types of calculations and computations. But, in late 19th century, people also started using this word to describe machines that performed all sorts of calculations. However, the modern-day usage of this word is used to describe many types of programmable electronic digital devices.<\/p>\n\n\n\n

As per Encyclopedia Britannica, \u2018The machine was designed to consist of four components: the mill, the store, the reader, and the printer. These components are the essential components of every computer today. The mill was the calculating unit, analogous to the central processing unit (CPU) in a modern computer; the store was where data were held prior to processing, exactly analogous to memory and storage in today\u2019s computers; and the reader and printer were the input and output devices.\u2019<\/p>\n\n\n\n

Early History of Computer<\/h2>\n\n\n\n

We humans have been using devices for day-to-day calculations for the past thousands of years. One vibrant example, and one of the earliest and well-known devices was an abacus. In 1822, the father of computers, Charles Babbage laid the foundations of the first mechanical computer. He then went on to design an Analytical Engine in 1833, which was a big-sized general-purpose computer. Although not actually completed, the Analytical Engine was the first machine that deserved to be called a computer. It contained an ALU, some basic flow chart principles and the concept of integrated memory. Then the first electronic computers called ENIAC were introduced for general purposes. ENIAC, stands for Electronic Numerical Integrator and Computer. The inventors of this computer were John W. Mauchly and J. Presper Eckert. Gradually the technology developed and the computers got smaller and the processing got faster. The first laptop was introduced by Adam Osborne and EPSON in the year 1981.<\/p>\n\n\n\n

Generations of Computers<\/h2>\n\n\n\n

In the history of computers, the advancements of modern computers is referred to as the generation of computers<\/strong>. Currently, we use the fifth generation of computers.<\/p>\n\n\n\n

1. First Generation Computer<\/h4>\n\n\n\n

Period: 1946 to 1959<\/strong><\/p>\n\n\n\n

2. Second Generation Computer<\/h4>\n\n\n\n

Period: 1959-1965<\/p>\n\n\n\n

3. Third Generation Computer<\/h4>\n\n\n\n

Period: 1965 to 1971<\/strong><\/p>\n\n\n\n

4. Fourth Generation Computer<\/h4>\n\n\n\n

Period: 1971 to 1980 <\/strong><\/p>\n\n\n\n

Important features of these five generations of computers<\/h2>\n\n\n\n

Given below are the important features of the five generations of computers that you should be well-aware of in order to deal with questions related to it:<\/p>\n\n\n\n

1. 1st Generation<\/strong><\/h4>\n\n\n\n

This was a time when the machine language was developed for the use of computers. People used vacuum tubes for the circuitry and used magnetic drums as the memory of the computer.<\/p>\n\n\n\n

2. 2nd Generation<\/strong><\/h4>\n\n\n\n

This was a time when computers advanced from vacuum tubes to transistors. The computers were made smaller, faster and more energy efficient. Plus, these machines advanced from binary to assembly languages.<\/p>\n\n\n\n

3. 3rd Generation<\/strong><\/h4>\n\n\n\n

The period of third generation was from 1965-1971. The computers of third generation used Integrated Circuits (ICs) in place of transistors.<\/p>\n\n\n\n

4. 4th Generation<\/strong><\/h4>\n\n\n\n

The invention of the microprocessors brought an era of the fourth generation of computers. This era saw computers for home use. This was also the time when higher computer languages like C++ and Java developed.<\/p>\n\n\n\n

5. 5th Generation<\/strong><\/h4>\n\n\n\n

Our present era of artificial intelligence comes under this generation of Computers and would most probably be the future of the computer world. The implementation of parallel processing and superconductors is widening its scope for our future generations.<\/p>\n\n\n\n
