11. A flip flop stores __________.
A. 10 bit of information
B. 1 bit of information
C. 2 bit of information
D. 3-bit information
ANSWER:B
SOLUTION:A flip-flop stores one bit of information. It is a basic building block of sequential circuits that can store a single bit (binary digit) of data. One of the two states represents a “one” and the other represents a “zero”.
12. A ROM is defined as _________.
A. Read Out Memory
B. Read Once Memory
C. Read Only Memory
D. Read One Memory
ANSWER: C
SOLUTION: ROM stands for read-only memory. It’s a type of non-volatile memory used in computers and other electronic devices to store data that cannot be electronically modified after the device is manufactured.
13. In a computer, registers are present _________________.
A. Within control unit
B. Within RAM
C. Within ROM
D. Within CPU
ANSWER:D
SOLUTION:Registers are present within the CPU (Central Processing Unit) of a computer.
14. ROM has the capability to perform _____________.
A. Write operation only
B. Read operation only
C. Both write and read operation
D. Erase operation
ANSWER:B
SOLUTION:ROM means “Read Only Memory”. Hence, it has capability to perform read operation only. No write or erase operation could be performed in the ROM.
15. A nibble is equal to ___ bits
A. 4
B. 8
C. 16
D. 32
ANSWER: A
SOLUTION: A nibble is equal to 4 bits
16. Cache and main memory will not be able to hold their contents when the power is off. They are ________.
A. Dynamic
B. Static
C. Volatile
D. Non- volatile
ANSWER: C
SOLUTION: Cache and main memory are volatile memory, which means they lose their contents when the power is off.
17. Storage that stores or retains data after power off is called __________.
A. Volatile storage
B. Non-volatile storage
C. Sequential storage
D. Direct storage
ANSWER: B
SOLUTION:Non-volatile storage is a type of computer memory that can retain stored information even after power is removed.
18. Main memory of the computer is ______.
A. Internal
B. External
C. (A) and (B)both
D. Auxiliary
ANSWER:A
SOLUTION:The main memory of a computer is internal memory, also known as primary memory.
19. Computer word size is a multiple of ________.
A. 16 bits
B. 4 bits
C. 1024 bits
D. 10 bits
ANSWER: A
SOLUTION:Computer word size is a multiple of 8 bits, which is also known as a byte.eight bits
Word sizes thereafter are naturally multiples of eight bits, with 16, 32, and 64 bits being commonly used.
