Question

Which among the following is false with respect to First generation of computers?
1. Generates large amount of heat 
2. Use of vacuum tubes to make circuits 
3. More reliable and less prone to hardware failure
4. Use of machine language and symbols in instructions

Answer 1

Correct Answer - Option 3 : More reliable and less prone to hardware failure

The correct answer is More reliable and less prone to hardware failure.

• First Generation of Computers
  • Period: 1946-1959
  • These computers used vacuum tubes as the basic components for memory and these tubes produce a lot of heat and the installation used to fuse frequently.
  • Its speed is 333 microseconds.
  • Its operating system is the batch operating system.
  • The language used: Machine language(Binary number 0s and 1s).

• Today we are using the first generation of computers. 
• The fifth generation of computers is using AI( artificial intelligence).
• Charles Babbage is called the father of computers.
• Alan Turing is known as the father of the modern computer.

Generation of computers	Features	Examples and Images
1st Generation	The period of the first generation of computers is 1946-1959. In this generation, Vaccum tube technology was used. Computers of this generation generate a large amount of heat. Therefore, these computers are not reliable and so expensive. The size of these computers is very big. These computers support machine Language only.	ENIAC EDVAC UNIVAC
2nd Generation	The period of the second generation was from 1959-1965. In this generation, Transistors were used. Transistors generate less amount of heat and more reliable as compared to first-generation computers. Computers of this generation are cheap and smaller in size than that of the 1sr generation. In this generation, assembly language and high-level programming languages like FORTRAN, COBOL was used.	IBM 1620 IBM 7094 CDC 1604
3rd Generation	The period of the third generation was from 1965-1971. Here IC's(Integrated Circuits) are used in place of Transistors. A single IC has many transistors, resistors, and capacitors along with the associated circuitry.  Due to this computer smaller in size, reliable and efficient.	IBM-360 series Honeywell-6000 series PDP (Personal Data Processor) IBM-370/168
4th Generation	The period of the fourth generation was from 1971-1980. In this generation, very large integrated circuits (VLIC)were used. VLIC has 500o transistors on a single cheap made it possible. These computers are more affordable, reliable, and compact. In this generation Real-time, the time-sharing operating system was used. All the high-level languages like C, C++ were used in this generation	DEC 10 STAR 1000 PDP 11 CRAY-1(Super Computer) CRAY-X-MP(Super Computer)
5th Generation	The period of fifth-generation is the 1980-till date. In this generation, VLIC is replaced by ULSI. ULSI is ultra large scale integration. This generation is based on Artificial Intelligence. AI is a branch in the computer which means and interprets to think computers like human brains. All the high-level languages like C and C++, Java, .Net, etc., are used in this generation.	Desktop Laptop Notebook Ultrabook Chromebook
