Explanation:
Q9. which memory is assembled between main memory and CPU ?
(A) primary memory
(B) secondary memory
(C) registers
(D) cache memory
Answer: cache memory
Explanation: The basic purpose of cache memory is to store program instructions that are frequently re-referenced by software during operation. Fast access to these instructions increases the overall speed of the software program. As the microprocessor processes data, it looks first in the cache memory; if it finds the instructions there, it does not have to do a more time-consuming reading of data from larger memory or other data storage devices.
Q10. which method is used to to establish priority by serially connecting all devices that request an interrupt?
(A) interrupt
(B) Polling
(C) priority
(D) Daisy Chaining
Answer: Daisy Chaining
Explanation: In electrical and electronic engineering a daisy chain is a wiring scheme in which multiple devices are wired together in sequence or in a ring. Other than a full, single loop, systems which contain internal loops cannot be called daisy chains.
Q11. which register is memory pointer of instruction
(A) instruction register
(B) stack pointer
(C) program counter
(D) source index
Answer: program counter
Explanation: A program counter is a register in a computer processor that contains the address of the instruction being executed at the current time. As each instruction gets fetched, the program counter increases its stored value by 1.
Q12. header of frame generally contains
(A) synchronisation bytes
(B) addresses
(C) frame identifier
(D) all of the mentioned
Answer: all of the mentioned
Explanation:
Q13. when one or more bits in a data unit has been changed during the transmission the error is called
(A) random error
(B) burst error
(C) inverted error
(D) none of the mentioned
Answer: burst error
Explanation:
Q14. ______ is a collection of point to point links that may form a circle
(A) WAN
(B) MAN
(C) Ring topology
(D) LAN
Answer: Ring topology
Explanation: In Ring Topology, all the nodes are connected to each-other in such a way that they make a closed loop. Each workstation is connected to two other components on either side, and it communicates with these two adjacent neighbors. Data travels around the network, in one direction. Sending and receiving of data takes place by the help of TOKEN.
Q15. which of the following uses FIFO method
(A) queue
(B) stack
(C) hash table
(D) binary search tree
Answer: queue
Explanation: FIFO is an acronym for first in, first out, a method for organizing and manipulating a data buffer, where the oldest (first) entry, or head of the queue, is processed first. It is analogous to processing a queue with first-come, first-served (FCFS) behaviour: where the people leave the queue in the order in which they arrive.
Q16. Heap is an example of
(A) complete binary tree
(B) spanning tree
(C) sparse tree
(D) binary search tree
Answer: complete binary tree
Explanation: A heap is a general term used for any memory that is allocated dynamically and randomly; i.e. out of order. The memory is typically allocated by the OS, with the application calling API functions to do this allocation.
Q17. in delta connected generator all of the phase voltages are
(A) zero
(B) sequel in magnitude
(C) one third of total
(D) one sixth of total
Answer: sequel in magnitude
Explanation:
Q18. Henry is equivalent to
(A) volts /ampere
(B) Weber/volt
(C) Weber/ampere
(D) Weber/ampere
Answer: Weber/ampere
Explanation:
Q19. in dc generator s, current to the external circuit from armature is given through
(A) solid connection
(B) slip rings
(C) commutator
(D) none of these
Answer: commutator
Explanation:

(A) in series with circuit
(B) in parallel with circuit
(C) either in series or in parallel with circuit
(D) none of the above
Answer: in series with circuit
