Computer fundamental MCQ Questions and answers- Technical Aptitude

The abacus is one of many counting devices invented in ancient times to help count large numbers, but it is believed that the abacus was first used by the Babylonians as early as 2,400 BC. The abacus was in use in Europe, China, and Russia, centuries before the adoption of the written Hindu-Arabic numeral system.

A class of random access memory that requires periodic servicing in order for the contents to remain valid is Dynamic RAM. Dynamic random-access memory (dynamic RAM or DRAM) is a type of random-access semiconductor memory that stores each bit of data in a memory cell, usually consisting of a tiny capacitor and a transistor, both typically based on metal-oxide-semiconductor (MOS) technology.

Programs are a set of instructions or ordered operations for a computer to perform a task. At first, a software program is developed followed by the creation of instructions or code for the program to be executed.

System resilience is an ability of the system to withstand a major disruption within acceptable degradation parameters and to recover within an acceptable time.

Dynamic Random Access Memory is the most common type of Random Access Memory for personal computers and workstations. DRAM has to be refreshed many times per second in order to hold its data contents.

The period of third generation was from 1965 - 1971. The computers of third generation used Integrated Circuits (ICs) in place of transistors.

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.

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.

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.

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.
