Computer fundamental MCQ Questions and answers- Technical Aptitude

An element in a computer CPU that transmits the location of stored information the address bus allows the CPU to send the address to RAM, and the data bus allows the actual data transfer to the CPU.

A microcomputer is a complete computer on a small scale, designed for use by one person at a time. An antiquated term, a microcomputer is now primarily called a personal computer (PC), or a device based on a single-chip microprocessor. Common microcomputers include laptops and desktops.

A small hole punched into a hard sectored floppy disk that serves to mark the start of the sectors on each track. Hard sectoring in a magnetic or optical data storage device is a form of sectoring which uses a physical mark or hole in the recording medium to reference sector locations. Soft sectored a floppy disk with a single index hole is known as a soft-sectored disk.

Ethernet is the technology that is most commonly used in wired local area networks (LANs). A LAN is a network of computers and other electronic devices that covers a small area such as a room, office, or building.

Bubble memory is a type of non-volatile computer memory that uses a thin film of a magnetic material to hold small magnetized areas, known as bubbles or domains, each storing one bit of data.

Memory protection is a way to control memory access rights on a computer and is a part of most modern instruction set architectures and operating systems. The main purpose of memory protection is to prevent a process from accessing memory that has not been allocated to it.

A 16-bit integer can store 216 (or 65,536) distinct values. In an unsigned representation, these values are the integers between 0 and 65,535; using two's complement, possible values range from −32,768 to 32,767. Hence, a processor with 16-bit memory addresses can directly access 64 KB of byte-addressable memory.

240 is the storage capacity of a Hollerith card which is organized into nibbles.
A punched card or punch card is a piece of stiff paper that can be used to contain digital data represented by the presence or absence of holes in predefined positions. Digital data can be used for data processing applications or, in earlier examples, used to directly control automated machinery.

A type of instruction that can produce several lines of machine language code is a Macro. In Excel, macro code is a programming code which is written in VBA (Visual Basic for Applications) language. The idea behind using a macro code is to automate an action which you perform manually in Excel, otherwise.

A common use of computer in office is for Word processing. Creating, editing, saving and printing documents. Copying, pasting, moving and deleting text within a document. Formatting text, such as font type, bolding, underlining or italicizing.
