KVS PGT Computer Science Question Paper - January 2017 (Question No 16-20)
Q 16. What is the bit rate for transmitting uncompressed 800 x 600 pixel color frame with 8 bits/pixel at 40 frames/second.
Q 16. What is the bit rate for transmitting uncompressed 800 x 600 pixel color frame with 8 bits/pixel at 40 frames/second.
1) 2.4 Mbps
2) 153.6 Mbps
3) 15.36 Mbps
4) 1536 Mbps
Answer : 2) 153.6 Mbps
Solution : The number of bit per second is 800 x 600 x 40 x 8 = 153600000 bps
(As One megabit per second (Mbps) is equal to 1,000,000 bps or 1,000 Kbps.)
So 153600000 bps = 153600000 Mbps = 153.6 Mbps
(1000 x 1000)
Q 17. What is the length of an IP address in bytes (Pre-IPv6).
1) 1
2) 4
3) 2
4) 8
Answer: N.A
Solution: (The length of an IPv6 address is 128 bits, compared with 32 bits in IPv4.)
Q 18. Program counter contents indicate:
1) The time elapsed since execution begins.
2) The count of programs being executed after switching the power ON.
3) The address where next instruction is stored.
4) The time needed to execute a program.
Q 19. Which of the following is the most appropriate format for graphics that are to be embedded within an internet document?
1) BMP
2) GIF
3) TIFF
4) HTML
Solution : The number of bit per second is 800 x 600 x 40 x 8 = 153600000 bps
(As One megabit per second (Mbps) is equal to 1,000,000 bps or 1,000 Kbps.)
So 153600000 bps = 153600000 Mbps = 153.6 Mbps
(1000 x 1000)
Q 17. What is the length of an IP address in bytes (Pre-IPv6).
1) 1
2) 4
3) 2
4) 8
Answer: N.A
Solution: (The length of an IPv6 address is 128 bits, compared with 32 bits in IPv4.)
Q 18. Program counter contents indicate:
1) The time elapsed since execution begins.
2) The count of programs being executed after switching the power ON.
3) The address where next instruction is stored.
4) The time needed to execute a program.
Answer : 3) The address where next instruction is stored.
Solution : A program
counter (PC) is a CPU register in the computer processor which has the
address of the next instruction to be executed from memory. It is a
digital counter needed for faster execution of tasks as well as for
tracking the current execution point.A program counter is also known as an instruction counter,
instruction pointer, instruction address register or sequence control
register.
Q 19. Which of the following is the most appropriate format for graphics that are to be embedded within an internet document?
1) BMP
2) GIF
3) TIFF
4) HTML
Answer : 2) GIF (Graphics Interchange Format)
Q 20. The technology that stores only the essential instructions on a microprocessor chip and thus enhances its speed is referred to as:
1) CISC
2) SIMD
3) RISC
4) MIMD
Answer : 3) RISC (Reduced instruction set computing)
Solution : RISC (reduced instruction set computer) is a
microprocessor that is designed to perform a smaller number of types of
computer instructions so that it can operate at a higher speed (perform
more millions of instructions per second, or MIPS).
