Computer fundamental MCQ Questions and answers- Technical Aptitude

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.

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.

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.

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.

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).

A memory element is any smallest part of such a system that possesses more than one stable state. Memory elements are employed specifically in computer memories and generally in sequential circuits. A memory element is any smallest part of such a system that possesses more than one stable state.

The Modula programming language is a descendant of the Pascal programming language. It was developed in Switzerland in the 1970s by Niklaus Wirth, the same person who designed Pascal.

In computing, the instruction registers (IR) or current instruction register (CIR) is the part of a CPU's control unit that holds the instruction currently being executed or decoded.

OCR : Optical character recognition is the mechanical or electronic conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene-photo or from subtitle text superimposed on an image.

A multipoint connection is a communication channel between two or more clients of the network, where all data sent by one client is received by all other clients.
