Computer fundamental MCQ Questions and answers- Technical Aptitude

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.

Motorola Mobility LLC, marketed as Motorola, is American consumer electronics and Telecommunications Company, and a subsidiary of Chinese multinational technology company Lenovo. The Mac transition to Intel processors was the process of changing the central processing unit (CPU) of Apple Inc.'s line of Mac computers, as well as its server offerings at the time, from PowerPC to Intel x86 processors.

The essential features of a number system are Radix and Set of distinct counting digits. A numeral system is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set, using digits or other symbols in a consistent manner.

Page is a high speed non-impact printers are fast enough to print the entire book in about 1 minute. On-impact printers print the characters without using ribbons. These printers print a complete page at a time so they are also called page printers. E.g. Ink-Jet printer, Laser printer etc.

An identifying label on the first record of magnetic tape is Tape label. Tape labels are identifiers given to volumes of magnetic tape. There are two kinds of tape labels. The first is a label applied to the exterior of tape cartridge or reel. The second is data recorded on the tape itself.

Supercomputer, any of a class of extremely powerful computers. The term is commonly applied to the fastest high-performance systems available at any given time. Such computers have been used primarily for scientific and engineering work requiring exceedingly high-speed computations.

A reflective marker that indicates the end of the usable tape is End-of-tape. Modern magnetic tape is most commonly packaged in cartridges and cassettes. The device that performs writing or reading of data is a tape drive. Autoloaders and tape libraries automate cartridge handling.

LCD clocks are not likely to be found on a PC main circuit board. The CPU requires a fixed number of clock ticks (or clock cycles) to execute each instruction. The faster the clock, the more instructions the CPU can execute per second. Therefore, clock is used to bring some regularity to the system.

A specific part of an arithmetic & logic unit that is used to perform the operation of multiplication is Multiplier. An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer.

A teleprinter (teletypewriter, teletype or TTY) is an electromechanical device that can be used to send and receive typed messages through various communications channels, in both point-to-point and point-to-multipoint configurations.
