Computer fundamental MCQ Questions and answers- Technical Aptitude

All computer monitors have at least two cables, a power cable and a data cable. The power cable connects to the power outlet, or better, a surge protector, and is what allows the monitor to turn on. The other cable is a data cable and is what allows the picture (data) from your computer to be displayed.

In a punched card system, data is processed by an accounting machine, keypunch machine, and sorter. Computer punched card reader a computer input device used to read executable computer programs and data from punched cards under computer control.

Minicomputers are small computers that were introduced in 1960 and are used for various business enterprises and scientific applications work. Microcomputers are kind of personal computers that are used for much general-purpose work and are introduced in 1970 to overcome most of the tasks.

The highest address possible if 16 bits are used for each address 65536 . For example, with a 16-bit address register, the address bus has 16 bits to address RAM and ROM. With 16 bits, a maximum of 216 = 65,536 words can be addressed. There are usually two other registers, the flag and stack pointer registers.

An integrated circuit (ICs) is an electronic device comprising numerous functional elements such as transistors, resistors, condensers, etc. on a piece of silicon semiconductor substrate, and is sealed inside a package with multiple terminals.

Magnetic-core memory (core memory) was the predominant form of RAM memory in b/n 1955 and 1975. Core uses tiny magnetic rings through which wires are threaded to write and read information. Core memory often refers to just the central RAM of a computer that stores programs that are currently running and that data that they are working on.

NuBus is a 32-bit parallel computer bus, originally developed at MIT and standardized in 1987 as a part of the NuMachine workstation project. The first complete implementation of the NuBus was done by Western Digital for their NuMachine, and for the Lisp Machines Inc.

Packet switching data transfer refers to protocols in which messages are divided into packets before they are sent. Each packet is then transmitted individually and can even follow different routes to the destination. Once all the packets forming a message arrive at the destination, they are recompiled into the original message.

A program is a set of instructions that can be executed by a computer to do a specific task. A collection of computer programs, libraries, and related data are referred to as software.

A simulator is a program or machine that simulates a real-life situation, meaning that it creates a virtual version of it, often for the purpose of instruction or experiment, such as a flight simulator.
