Solutions
S1. Ans.(c)
Sol. Data is organized in a data storage hierarchy of increasingly complex levels: bits, bytes (characters), fields, records, files, and databases. A character is a letter, number, or special character. A field consists of one or more characters (bytes). A record is a collection of related fields.
S2. Ans.(d)
Sol. The analytical engine developed during first generation of computers used counter wheels as a memory unit.
S3. Ans.(d)
Sol. All these devices can be used for the data backup.
S4. Ans.(b)
Sol. Motherboard is used to hold ROM, RAM, CPU and expansion cards.
S5. Ans.(d)
Sol. Nibble (often nybble or nyble to match the vowels of byte) is a four-bit aggregation, or half an octet. It is also known as half-byte or tetrade.
S6. Ans.(a)
Sol. The permanent memory that comes built into a computer is called read-only memory, or ROM. Read-only memory typically holds the most basic level of software that a computer needs to run.
S7. Ans.(b)
Sol. Main memory works in conjunction with CPU, it can be directly accessed by the CPU.
S8. Ans.(b)
Sol. Magnetic Tape is a sequential access medium so it can be quite slow to access data directly by the CPU.
S9. Ans.(c)
Sol. Static random-access memory (static RAM or SRAM) is a type of semiconductor memory that uses bistable latching circuitry (flip-flop) to store each bit.
S10. Ans.(d)
Sol. Semiconductor Memory Ram is a Volatile memory (loses data when power goes OFF). Magnetic Memory is nonvolatile (doesn't not lose data when power goes OFF).
S11. Ans.(a)
Sol. Read-only memory. ROM is computer memory on which data has been prerecorded. It retains its contents even when the computer is turned off.
S12. Ans.(a)
Sol. Virtual memory is a memory on the hard disk that the CPU uses as an extended RAM.
S13. Ans.(a)
Sol. Another name for flash memory is Flash RAM.
S14. Ans.(b)
Sol. USB is defined as an acronym that stands for Universal Serial Bus which is a type of computer port which can be used to connect equipment to a computer.
S15. Ans.(a)
Sol. Winchester disk also known as disk stack.
