Early History of Computers

Since the evolution of humans, devices have been used for calculations for thousands of years. One of the earliest and most well-known devices was the abacus. Then in 1822, the father of computers, Charles Babbage began developing what would be the first mechanical computer. And then in 1833 he designed an Analytical Engine which was a general-purpose computer. It contained an ALU, some basic flow chart principles, and the concept of integrated memory.

Then more than a century later in the history of computers, we got our first electronic computer for general purposes. It was the ENIAC, which stands for Electronic Numerical Integrator and Computer. The inventors of this computer were John W. Mauchly and J.Presper Eckert.

And with time, technology developed and the computers got smaller and the processing got faster. We got our first laptop in 1981 and it was introduced by Adam Osborne and EPSON.

Generations of Computers

1st Generation: This was from the period of 1940 to 1955. This was when machine language was developed for the use of computers. They used vacuum tubes for the circuitry. For memory, they used magnetic drums. These machines were complicated, large, and expensive. They were mostly reliant on batch operating systems and punch cards. As output and input devices, magnetic tape and paper tape were implemented. For example, ENIAC, UNIVAC-1, EDVAC, and so on.

2nd Generation: The years 1957-1963 were referred to as the “second generation of computers” at the time. In second-generation computers, COBOL and FORTRAN are employed as assembly languages and programming languages. Here they advanced from vacuum tubes to transistors. This made the computers smaller, faster, and more energy-efficient. And they advanced from binary to assembly languages. For instance, IBM 1620, IBM 7094, CDC 1604, CDC 3600, and so forth.

3rd Generation: The hallmark of this period (1964-1971) was the development of the integrated circuit.  A single integrated circuit (IC) is made up of many transistors, which increases the power of a computer while simultaneously lowering its cost. These computers were quicker, smaller, more reliable, and less expensive than their predecessors. High-level programming languages such as FORTRON-II to IV, COBOL, and PASCAL PL/1 were utilized. For example, the IBM-360 series, the Honeywell-6000 series, and the IBM-370/168.

4th Generation: The invention of the microprocessors brought along the fourth generation of computers. The years 1971-1980 were dominated by fourth-generation computers. C, C++, and Java were the programming languages utilized in this generation of computers. For instance, the STAR 1000, PDP 11, CRAY-1, CRAY-X-MP, and Apple II. This was when we started producing computers for home use.

5th Generation: These computers have been utilized since 1980 and continue to be used now. This is the present and the future of the computer world. The defining aspect of this generation is artificial intelligence. The use of parallel processing and superconductors are making this a reality and providing a lot of scope for the future. Fifth-generation computers use ULSI (Ultra Large Scale Integration) technology. These are the most recent and sophisticated computers. C, C++, Java,.Net, and more programming languages are used. For instance, IBM, Pentium, Desktop, Laptop, Notebook, Ultrabook, and so on.

Answer:

- Civil Rights Movement

- Anti-War Movement

- Feminism

Explanation:

- The 1960s saw the height of the Civil Rights Movement, which aimed to end racial segregation and discrimination in the United States. The movement led to the passage of several landmark civil rights laws, including the Civil Rights Act of 1964 and the Voting Rights Act of 1965.

- The Vietnam War sparked widespread protests and opposition, particularly among young people and the counterculture. The anti-war movement helped to fuel a broader sense of political activism and engagement.

- The feminist movement emerged in the 1960s, advocating for women's rights, such as reproductive rights and equal pay for equal work.
