What are the features of second generation computer?
Features of the Second Generation of Computers
- As the computers made in the second generation used transistors that made them more reliable, smaller in size, faster in speed, more energy-efficient, and cheaper compared to the first generation of computers.
- They contain magnetic storage disks and magnetic core memory.
What is the 2nd generation of computer?
They are also known as transistor computers. The second generation of computers consists of two types of devices, transistors, and magnetic core. The transistors helped to develop a better computer than the first generation computers consisting of vacuum tubes.
What are the main components of second generation?
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 are the main features of computer generation?
Features of the third generation computers are: The technology used: IC (Integrated Circuit). Transistors were replaced by IC in their electronic circuitry. High-level languages like FORTAN , BASIC and other are used to develop programs. Semiconductor memory like RAM and ROM were used as primary memory.
What are the four features of second generation computer?
FEATURES OF SECOND GENERATION COMPUTERS
- Transistors – small, low-power, low-cost, more reliable than vacuum tubes.
- Magnetic core memory.
- Two’s complement, floating point arithmetic.
- Reduced the computational time from milliseconds to microseconds.
- High level languages.
- First operating Systems: handled one program at a time.
What are 4 generations?
Leading the Four Generations at Work
- Silents (Born between 1925 and 1946)
- Baby Boomers (Born between 1946 and 1964)
- Generation Xers (Born between 1965 and 1980)
- Generation Ys or Millennials (born after 1980)
What is difference between first and second generation of computer?
1) The first generation computer made use of vacuum tubes as internal component, whereas transistors were used in the second generation. 5) The main memory of the first generation computer is in form of magnetic drum, while the main memory of the second generation computer is in form of RAM and ROM.
What is the main component of first generation?
First Generation Computers The computers of first generation used vacuum tubes as the basic components for memory and circuitry for CPU (Central Processing Unit). These tubes, like electric bulbs, produced a lot of heat and the installations used to fuse frequently.
Which is the basic component of second generation of computer?
Transistors
1.3.2 Second Generation Computers: Transistors (1956-1963) Solid-State components (transistors and diodes) and magnetic core storage formed the basis for the second generation of computers.
What are the three features of first generation computer?
Features of first generation computers:Technology used: vacuum tube. Machines languages were used to instruct the computer. Magnetic core memory was used as primary memory. Electrostatic tubes, Parer tape, punch card, magnetic tape.
What are the characteristics of the second generation computer?
The following are the characteristics of second generation computers : Solid state electronic components such as transistor and diodes were used as the principal electronic components in the second generation of computers. Speed was normally measured in microseconds.
What was the programming language of the second generation of computers?
In this generation, assembly language and high-level programming languages like FORTRAN, COBOL were used. The computers used batch processing and multiprogramming operating system. The main features of second generation are −. Use of transistors.
What’s the difference between the third and fourth generation computers?
Third generation minicomputers were essentially scaled-down versions of mainframe computers, whereas the fourth generation’s origins are fundamentally different. The basis of the fourth generation is the microprocessor, a computer processor contained on a single large-scale integration (LSI) MOS integrated circuit chip.
Why was the minicomputer important in the 1960s?
The integrated circuit enabled the development of much smaller computers. The minicomputer was a significant innovation in the 1960s and 1970s. It brought computing power to more people, not only through more convenient physical size but also through broadening the computer vendor field.
