What are second generation computers?
A transistor computer, now often called a second generation computer, is a computer which uses discrete transistors instead of vacuum tubes. A second generation of computers, through the late 1950s and 1960s featured circuit boards filled with individual transistors and magnetic core memory.
What is the main component of 2nd generation computer?
The second generation computers used transistors as the basic components. The first transistor was developed at bell laboratories on 1947 by William Shockley, John Bardeen and Walter Houser Brattain. The size of transistor is small compared to the size of vacuum tubes. Transistors are made from silicon.
What were the limitations of first and second generation of computer?
Limitations of second–generation computers were: They used transistors as their main component. They were smaller, faster and more efficient than first–generation computers. They also contained all the components we associate with modern-day computers like printer, memory, disk storage, operating system.
Is an example of second generation computer?
Examples of the second generation computers include IBM 1620, IBM 7094, CDC 1604, CDC 3600, UNIVAC 1108. As a result, they worked on AC and therefore were faster than their predecessors.
What are the major limitations of first generation of computer?
The major limitations of first generation computers. The operating speed was very low. Power consumption was very high. They required large space for installation.
Who found second generation computer?
The computers made in the second generation were completely based upon transistors, not on vacuum tubes. Until the late 1950s, the use of transistor did not see widespread in computers; however, it was invented at Bell Labs by Walter H. Brattain (1902-1987), John Bardeen (1908-1991), and William B.
What is the difference between 1st generation and 2nd generation computers?
in First Generation, Vacuum tubes were used as internal components. in Second Generation Transistors were used as internal component. in SG The sizes of computer were smaller than first generation & were called as mini computer. 3.
What is the 4 generation of computer?
The period of fourth generation was from 1971-1980. Computers of fourth generation used Very Large Scale Integrated (VLSI) circuits. VLSI circuits having about 5000 transistors and other circuit elements with their associated circuits on a single chip made it possible to have microcomputers of fourth generation.
What is the name of first generation of computer?
vacuum tubes are known as first–generation computers. (With 1,500 mechanical relays, ENIAC was still transitional to later, fully electronic computers.)
What is computer generation and types?
Generation in computer terminology is a change in technology a computer is/was being used. Initially, the generation term was used to distinguish between varying hardware technologies. Nowadays, generation includes both hardware and software, which together make up an entire computer system.
What was the 1st generation computer used for?
First Generation Computers
Therefore, they were very expensive and only large organizations were able to afford it. In this generation, mainly batch processing operating system was used. Punch cards, paper tape, and magnetic tape was used as input and output devices.
What are the 5 types of computer generation?
There are five generations of computers.
- FIRST GENERATION.
- SECOND GENERATION.
- THIRD GENERATION.
- FOURTH GENERATION.
- FIFTH GENERATION.
Which computer generation is best?
Fourth and Fifth Generations of computer is best.
Which generation of computer we are using now?
While the third generation is considered by many people to have spanned from 1964 to 1971, IC’s are still used in computers today. Over 45 years later, today’s computers have deep roots going back to the third generation.
What are the basic difference between the four generation of computer?
Diference between different generation of computers
| Particulars | First | Fourth |
|---|---|---|
| Size | Room Size | Typewriter Sized Computers & Laptops |
| Density | One Component per Circuit | Hundreds of Thousands of Components per Circuit |
| Technology | Vacuum Tubes | Large Scale Integrated Semiconductor Circuits |
| Main Memory | Magnetic Drum | LSI Semiconductor Circuits |

What is the sixth generation of computer?
Sixth Generation of Computers:
These computers are called intelligent computers based on artificial intelligence or artificial brains. Whereas, it uses the semiconductors as the raw material to its processors.
What are different computer generations?
The period 1956 to 1963 is roughly considered as the period of Second Generation of Computers. The second generation computers were developed by using transistor technology. In comparison to the first generation, the size of second generation was smaller.
Which generation is high level language developed?
Third Generation (3GL)
3GLs are more abstract than previous generations of languages, and thus can be considered higher–level languages than their first- and second-generation counterparts. First introduced in the late 1950s, Fortran, ALGOL, and COBOL are examples of early 3GLs.
What are the characteristics of the fourth generation computer?
1) The fourth generation computers have microprocessor-based systems. It uses VLSI (Very Large Scale Integrated) circuits. 2) They are the cheapest among all the computer generation. 3) The speed, accuracy and reliability of the computers were improved in fourth generation computers.
What are the five high level languages?
Commonly used high–level languages
- Python.
- Java.
- C++
- C#
- Visual Basic.
- JavaScript.
Which language is a 3 GL?
Commonly known 3GLs are FORTRAN, BASIC, Pascal and the C-family (C, C+, C++, C#, Objective-C) of languages. Also known as a 3rd generation language, or a high-level programming language.
