Computer fundamental MCQ Questions and answers- Technical Aptitude

Hardware LIFO memory is seldom used in modern computers. Short for last in, first out, LIFO is a method of processing data where the data last received is the first to be sent out after processed.

In 1968, while employed at the United States National Radio Astronomy Observatory (NRAO), Moore invented the initial version of the Forth language to help control radio telescopes.

An IC contains 50 gates each of which consists of 6 components. Its belong to MSI, Medium Scale Integration or (MSI) - between 10 and 100 transistors or tens of gates within a single package and perform digital operations such as adders, decoders, counters, flip-flops and multiplexers.

NOR gate is a digital logic gate. It implements logical NOR. It behaves according to the truth table to the right. A HIGH output (1) results if both the inputs to the gate are LOW (0). If one or both input is HIGH (1), a LOW output (0) results. NOR is the result of the negation of the OR operator. It can also be seen as an AND gate with all the inputs inverted. NOR is a functionally complete operation. It combinations of NOR gates can be combined to generate any other logical function.

Basically a CPA network is a network that focuses mainly on Cost-Per-Action or Cost-Per-Acquisition advertising. It's a type of Affiliate Marketing, but often focuses on leads over sales, but not exclusively. It's a little complex, but its a great way to generate a lot of leads or sales really fast.

A large computer designed to handle complex scientific calculations may use only a firmed word-length storage approach. It is used for scientific and engineering applications that must handle very large databases or do a great amount of computation.

ASCII, abbreviation of American Standard Code For Information Interchange, a standard data-transmission code that is used by smaller and less-powerful computers to represent both textual data and no input-device commands (control characters).

A technique for processing jobs on a first-come, first-served basis is known as FIFO. The phrase is often but erroneously stated as "first come, first serve" (instead of "served").FIFO is the acronym for First-In, First-Out.

A device mounted on a communication satellite which receives, amplifies and re-transmits signals from earth station is transponder. A transponder is typically composed of: an input band-limiting device (an input band-pass filter), an input low-noise amplifier (LNA), designed to amplify the signals received from the Earth station.

Pseudo code is commonly used to teach algorithms for computer science students in an introductory programming course. When an automatic translation tool is available, students can translate their pseudo code to source code and then execute the resulted source code to check whether their algorithm is correct.
