Computer Fundamentals (NCO)

In assembly language, a mnemonic is a symbol which is entered in the operation code of each assembler program.

Backing store can make a copy of all information stored on a disk and restore the entire disk or selected files.

It is responsible for overall functions of the computer. It tells us that which computer program and instructions are executed and coordinates the activity of the computer.

Rotational delay is the amount of time it takes for the disk to rotate until the required location on the disk reaches the read/write head.

It is a data transmission in which a single wire can carry several channels at once.

It is the conversion of data into a secret code for transmission over a network. It can't be easily understood if intercepted.

Language processor is the correct answer. All compiler, assembler and interpreter fall under this category.

Dynamic Random Access memory: It is the memory that requires refreshing every few milliseconds. It stores each bit of data in a separate capacitor within an integrated circuit.

It is a storage device, which is used to store data or information. CD, DVD, Hard disk or floppy are types of disks.

The language used in source program and from which translation is to be done

Optical Character Recognition: It involves reading text from paper and translating the images into a form that a computer can manipulate.

It is a sequence of coded instructions written to perform a specified task.

Badge reader is a data input device or electronic sensor that reads coded data from a small plastic card shaped storage medium.

It is an input device, which is used to point and select any option on video display unit.

It is container for data to be stored. It is a bag that contains items, or a set of things agreed to as a whole. In packing, data is packed in such a way that large amount of data can be stored on a small space.
