[#1006] How many symbols exist in Baudot code?
Correct Answer

(C) 32

Explanation

Solution: The Baudot code or International Teleprinter Code was invented by Emile Baudot in 1870. It is binary code which uses crosses and dots. It was used for teleprinter messages instead of the Morse code and allowed to encode 2 5 = 32 characters efficiently. Baudot is a five-bit binary code. Originally used in wireless telegraphy as a replacement for Morse code.

[#1007] Which gate sends on a pulse when it receives one at either or both of its terminals.
Correct Answer

(C) OR

Explanation

Solution: The OR gate gets its name from the fact that it behaves after the fashion of the logical inclusive "or". The output is "true" if either or both of the inputs are "true." If both inputs are "false," then the output is "false". In other words, for the output to be 1, at least input one OR two must be 1. The XOR (exclusive-OR) gate acts in the same way as the logical "either/or". The output is "true" if either, but not both, of the inputs are "true". The output is "false" if both inputs are "false" or if both inputs are "true". Another way of looking at this circuit is to observe that the output is 1 if the inputs are different, but 0 if the inputs are the same.

[#1008] A circuit which can store information is known as
Correct Answer

(C) Memory cell

Explanation

Solution: A circuit which can store information is known as Memory cell. But memory is a key element of digital systems. In computers, it allows to store both programs and data and memory cells are also used for temporary storage of the output of combinational circuits to be used later by digital systems.

[#1009] Where was the India's first computer installed and when?
Correct Answer

(C) Indian Statistical Institute, Calcutta, 1955

Explanation

Solution: The computer age in India began in 1955 with the installation of HEC-2M (a computer designed by A.D.Booth in England) at the Indian Statistical Institute (ISI) at Calcutta (now Kolkata)

[#1010] A language based on graphics for use in education is
Correct Answer

(B) LOGO

Explanation

Solution: Logo is a simple computer programming language which can be used to control devices. For example, a small robot known as a turtle can be moved around the floor using logo. Logo is often used with a screen turtle, which is an object on the screen used to simulate how a turtle moves around the floor.
