Computer fundamental MCQ Questions and answers- Technical Aptitude

A dot matrix printer (DMP) is a type of printer which uses pins impacting an ink ribbon to print. These printers are generally considered outdated, as they cannot create high-quality prints and are costly as well. However, they have a certain specialty that other printers like inkjet and laser printers do not have: as they use impact for printing, they can be used to print multiple copies of text at the same time with the help of carbon copying. Therefore, they are mostly used in places where multipart forms are required.
A dot matrix printer is also known as an impact matrix printer.

In computing, the expansion card, expansion board, adapter card or accessory card is a printed circuit board that can be inserted into an electrical connector, or expansion slot, on a computer motherboard, backplane or riser card to add functionality to a computer system via the expansion bus.

A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions.

Imaging, Graphics and Voice require large computers memory. Primary storage, also known as main storage or memory, is the area in a computer in which data is stored for quick access by the computer's processor.

Registers : In computer architecture, a processor register is a quickly accessible location available to a computer's central processing unit. Registers usually consist of a small amount of fast storage, although some registers have specific hardware functions, and may be read-only or write-only.

SCSI : Small Computer System Interface is a set of standards for physically connecting and transferring data between computers and peripheral devices. The SCSI standards define commands, protocols, electrical, optical and logical interfaces.

John William Mauchly and J. Presper Eckert are the scientists credited with the invention of the Electronic Numerical Integrator And Computer (ENIAC), the first general-purpose electronic digital computer, which was completed in 1946.

Bus arbitration : Bus arbitration is the process by which the next device to become the bus master is selected and bus mastership is transferred to it. The selection of bus master is usually done on the priority basis. There are two approaches to bus arbitration: Centralized and distributed.

In mathematics and mathematical logic, Boolean algebra is the branch of algebra in which the values of the variables are the truth values true and false, usually denoted 1 and 0 respectively.

In Synchronous Transmission, data is sent in form of blocks or frames. This transmission is the full duplex type. Between sender and receiver the synchronization is compulsory. In Synchronous transmission, There is no gap present between data.
