[#1076] The third generation of computers covers the period:
Correct Answer
(D) 1965 - 1971
Explanation
Solution: The period of third generation was from 1965 - 1971. The computers of third generation used Integrated Circuits (ICs) in place of transistors.
[#1077] An electronic logic gate whose output is logic 0 only when all inputs are logic 1 is
Correct Answer
(B) NAND
Explanation
Solution: A logic gate whose output will be in logic O state only when all inputs are in logic 1 state is called NAND. The NAND gate gives 0 as the output when both of its inputs are 1 or any one of the input is 1.
[#1078] Which of the following is the expansion of EBCDIC
Correct Answer
(C) Extended binary coded decimal interchange code
Explanation
Solution: EBCDIC, in full extended binary-coded decimal interchange code, data-encoding system, developed by IBM and used mostly on its computers, that uses a unique eight-bit binary code for each number and alphabetic character as well as punctuation marks and accented letters and non alphabetic characters.
[#1079] A vertically aligned set of tracks on a disk pack is known as
Correct Answer
(C) Cylinder
Explanation
Solution: A vertically aligned set of tracks on a disk pack is known as Cylinder. A term used to describe a 'logical' part of a hard disk storage device. A hard disk is usually made up of a number of physical platters stacked above each other, all spinning on a single spindle.
[#1080] Which is an electronic device that can store temporarily a single bit of data.
Correct Answer
(D) Latch
Explanation
Solution: Latches and flip-flops are the basic elements for storing information. One latch or flip-flop can store one bit of information. There are basically four main types of latches and flip-flops: SR, D, JK and T.
