[#961] A connection between two end points, either physical or logical, over which data may travel in both directions simultaneously is called _____
Correct Answer

(C) Duplex

Explanation

Solution: A connection between two end points, either physical or logical, over which data may travel in both directions simultaneously is called duplex. Full-duplex data transmission means that data can be transmitted in both directions on a signal carrier at the same time.

[#962] Which is part of a computer system, enables human operators to communicate with the computer.
Correct Answer

(A) Console

Explanation

Solution: Alternatively referred to as a computer console, root console, system console, or terminal. Console is a basic computer or monitor and keyboard that is connected to another computer, server or a mainframe over a network. It is used to maintain or monitor the status of the network or computer.

[#963] Who invented the microprocessor?
Correct Answer

(A) Marcian E Hoff

Explanation

Solution: Microprocessors were invented by - Ted Hoff, along with a handful of visionary colleagues working at a young Silicon Valley start-up called Intel. Marcian “Ted” Hoff (PhD '62 EE), is best known as the architect of the first microprocessor. Intel's 4004 were released in November 1971, 35 years ago this month.

[#964] Sending data from one place to another, by physical or electronic means is
Correct Answer

(C) Data transmission

Explanation

Solution: Data transmission is the transfer of data over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires, optical fibers, wireless communication channels, storage media and computer buses.

[#965] A method for representing digital data analog signals by changing the phase of the analog carrier to represent the digital information is known as
Correct Answer

(B) PSK

Explanation

Solution: Phase-shift keying (PSK) is a method of digital communication in which the phase of a transmitted signal is varied to convey information. There are several methods that can be used to accomplish PSK. The simplest PSK technique is called binary phase-shift keying (BPSK). It uses two opposite signal phases (0 and 180 degrees).
