Computer fundamental MCQ Questions and answers- Technical Aptitude

An input device is used to send data into the computer for processing.

A paper tape reader is a type of input device that reads the holes punched into paper tape and converts the data into a binary format that the computer can understand.

It interprets the pattern of holes as binary code and transmits it digitally into the system.

Paper tape punch is an output device used to punch holes into the tape, not to read it.

Page reader and card punch also do not serve the purpose of reading punched paper tape.

Therefore, the correct device for this function is the paper tape reader.

The computer's BIOS contain simple instructions, stored as data in electronic memory, to move data in and out of different storage locations and around the computer for processing.

Stack memory is a memory usage mechanism that allows the system memory to be used as temporary data storage that behaves as a first-in-last-out buffer. One of the essential elements of stack memory operation is a register called the Stack Pointer.

Stands for "Visual Display Unit". A VDU displays images generated by a computer or other electronic device. Visual display units may be peripheral devices or may be integrated with the other components. For example, the Apple iMac uses an all-in-one design, in which the screen and computer are built into a single unit.

Plotter accuracy is measured in terms of repeatability and resolution. In computers, resolution is the number of pixels (individual points of color) contained on a display monitor, expressed in terms of the number of pixels on the horizontal axis and the number on the vertical axis.

The minimum time delay required between the initiation of two successive memory operations is known as memory cycle time. Because of this, the minimum time delay between the initiations of two independent memory operations is called cycle time.

One thousand kilobytes (1000 KB) is equal to one megabyte (1 MB), where 1 MB is one million bytes. There are (from largest to smallest): Gigabytes (GB), Megabytes (MB), Kilobytes (KB), Bytes and Bit. But that really doesn't tell you much other than a gigabyte is bigger than a kilobyte.

The flow and timing to data to and from the microprocessor is regulated by control pins. Control pins are used in conjunction with a downspout and metal level control system to the regulate flow of molten metal from the distribution launder into moulds for rolling ingot and T-ingot casting processes.

In computer systems, especially in data processing and telecommunications, the term "volume" refers to the quantity of data or messages being handled or processed.

The total number of messages handled by a computerized telephone system on a daily basis represents the amount of data or workload the system processes.

This is best described as "volume" because it indicates the size or magnitude of data rather than how often (frequency) or whether it's being changed (updating).

Frequency refers to how often something happens, not how much.

Updating refers to changing or modifying existing data.

Hence, only Option C correctly describes the situation.

An internal storage consisting of arrays of small rings of magnetic material called ferrite is Magnetic core. Magnetic-core memory, also called core memory or magnetic-core storage, any of a class of computer memory devices consisting of a large array of tiny toruses of a hard magnetic material that can be magnetized in either of two directions. The two directions can represent either of the values, 0 or 1, in a binary bit.
