Computer fundamental MCQ Questions and answers- Technical Aptitude

A number that is used to control the form of another number is known as mask.

A personal computer is a general-purpose computer whose size, capabilities and original sale price make it useful for individuals and is intended to be operated directly by an end-user with no intervening computer operator.

ASCII, abbreviated from American Standard Code for Information Interchange, is a character encoding standard for electronic communication. ASCII codes represent text in computers, telecommunications equipment, and other devices. Most modern character-encoding schemes are based on ASCII, although they support many additional characters.

Mouse : A computer mouse with the most common features: two buttons (left and right) and a scroll wheel, which can also act as a third button. A computer mouse is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface. The first public demonstration of a mouse controlling a computer system was in 1968.
Originally wired to a computer, many modern mouse are cordless, relying on short-range radio communication with the connected system. Mouse originally used a ball rolling on a surface to detect motion, but modern mouse often have optical sensors that have no moving parts. In addition to moving a cursor, computer mouse have one or more buttons to allow operations such as selection of a menu item on a display. Mouse often also feature other elements, such as touch surfaces and "wheels", which enable additional control and dimensional input.

Intel MCS-80 is based on the widely used Intel 8080 microprocessor
The MCS-80 (Micro Computer Set-80) was a family of 8-bit microprocessor chipsets developed by Intel. Introduced on April, 1974, the MCS-80 featured the 8080 CPU, the forefather of all modern x86-based microprocessors.

Programming languages available included Babbage (a high-level assembly language)
The GEC 4000 was a series of 16/32-bit minicomputers produced by GEC Computers Ltd. of the UK during the 1970s, 1980s and early 1990s.

Common types of backing storage devices are hard drives, SSD, external hard disk drives, optical media such as CD or DVD, and flash media such as thumbdrives and memory sticks.

Plotter : The plotter is a computer printer for printing vector graphics. In the past, plotters were used in applications such as computer-aided design, though they have generally been replaced with wide-format conventional printers. A plotter gives a hard copy of the output. It draws pictures on a paper using a pen.

Computer program : A computer program is a collection of instructions that performs a specific task when executed by a computer. A computer requires programs to function. A computer program is usually written by a computer programmer in a programming language.
