[#1016] Super computers are primarily useful for
Correct Answer

(C) Mathematical-intensive scientific applications

Explanation

Solution: Supercomputer, any of a class of extremely powerful computers. The term is commonly applied to the fastest high-performance systems available at any given time. Such computers have been used primarily for scientific and engineering work requiring exceedingly high-speed computations.

[#1017] A reflective marker that indicates the end of the usable tape is
Correct Answer

(B) End-of-tape

Explanation

Solution: A reflective marker that indicates the end of the usable tape is End-of-tape. Modern magnetic tape is most commonly packaged in cartridges and cassettes. The device that performs writing or reading of data is a tape drive. Autoloaders and tape libraries automate cartridge handling.

[#1018] Which of the following are not likely to be found on a PC main circuit board
Correct Answer

(D) LCD clocks

Explanation

Solution: LCD clocks are not likely to be found on a PC main circuit board. The CPU requires a fixed number of clock ticks (or clock cycles) to execute each instruction. The faster the clock, the more instructions the CPU can execute per second. Therefore, clock is used to bring some regularity to the system.

[#1019] A specific part of an arithmetic & logic unit that is used to perform the operation of multiplication is
Correct Answer

(A) Multiplier

Explanation

Solution: A specific part of an arithmetic & logic unit that is used to perform the operation of multiplication is Multiplier. An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer.

[#1020] Which of the following is used for input and output both
Correct Answer

(B) Teletype terminal

Explanation

Solution: A teleprinter (teletypewriter, teletype or TTY) is an electromechanical device that can be used to send and receive typed messages through various communications channels, in both point-to-point and point-to-multipoint configurations.
