Computer Knowledge Questions on Memory | Set – 48

Correct Answer: C. Non-volatile storage

Explanation- Non-volatile memory (NVM) or non-volatile storage is a type of computer memory that can retrieve stored information even after having been power cycled. In contrast, volatile memory needs constant power in order to retain data.

Correct Answer – A. ROM

Explanation-Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be electronically modified after the manufacture of the memory device.

Correct Answer – C. Dynamic RAM

Explanation- Dynamic RAM must be refreshed many times per second. Dynamic RAM is the most common type of memory in use today. Inside a dynamic RAM chip, each memory cell holds one bit of information and is made up of two parts: a transistor and a capacitor. These are, of course, extremely small transistors and capacitors so that millions of them can fit on a single memory chip.

Correct Answer – B. Character, Field, Record, File, Database

Explanation-

Character – Group of bytes.
Field – Heading of table
Record – Group of fields.
File – collection of record
Database – the collection of related files.

Correct Answer – A. nibble

Explanation-A nibble is a four-bit aggregation, or half an octet. It is also known as half-byte or tetrade. In a networking or telecommunication context, the nibble is often called a semi-octet, quadbit, or quartet. A nibble has sixteen possible values. A nibble can be represented by a single hexadecimal digit and called a hex digit.

Correct Answer: B. Pages

Explanation- Frames – Physical memory is broken into fixed-sized blocks

Pages – Logical memory is broken into blocks of the same size.

Correct Answer – B. ROM

Explanation- Read only memory (ROM) is the permanent memory which is used to store these important control programs and systems software to perform functions such as booting up or starting up programs. ROM is non-volatile. That means the contents are not lost when the power is switched off.

Correct Answer – C. disk stack

Explanation- A Winchester disk is a Disk Stack. Another term for hard disk drive. The term Winchester comes from an early type of disk drive developed by IBM that had 30MB of fixed storage and 30MB of removable storage.

Correct Answer – C. RAM

Explanation- RAM (Random Access Memory) is the hardware in a computing device where the operating system (OS), application programs and data in current use are kept so they can be quickly reached by the device’s processor.

Correct Answer: B. Motherboard

Explanation- Motherboard is specifically refers to a PCB with expansion capability and as the name suggests, this board is often referred to as the “mother” of all components attached to it, which often include peripherals, interface cards, and daughtercards: sound cards, video cards, network cards, hard drives, or other forms of persistent storage; TV tuner cards, cards providing extra USB or FireWire slots and a variety of other custom components.
