program to reflect the assigned address is called relocation

442)1 Sector= 4096 bytes

443) Two stacks of size required to implement a queue of size n

444) 1 Floppy = 6, 30,784 bytes or 308 KB

445) Consider a machine with 64 MB physical memory and a 32-bit virtual address

space. If the page size is 4 KB, then

size of the page table is 2 MB

446) Consider a virtual memory system with FIFO page replacement policy. For an

arbitrary page access pattern,

increasing the number of page frames in main memory will always decrease the

number of page faults

447) Consider a scheme R(A, B, C, D) and functional dependencies A->B and C-> D.

Then the decomposition of R into R1

(AB) and R2 (CD) is dependency preserving and lossless join

448) Main memory requires a device driver

449) RAM can be divided into 2 types

450) Two friends suitably arrange 4 blocks of different colors to exchange coded

information between them. 4 bits of

information is one exchanging each time

451) Cache memory is a part of main memory

452) The number 43 in 2’s complement representation is 01010101

453) The 8085 microprocessor responds to the presence of an interrupt by checking

the TRAP pin for ‘high’ status at the

end of each instruction fetch

454) All machinery and apparatus of computer is called hardware

455) The number 1024 bytes is the complement representation of 1 Kilo byte

456) System design specifications do not include blueprint showing the layout of


457) Web pages are uniquely identified using URL

458) The results of arithmetic and logical operations are stored in an accumulator

459) The input device that is closely related to touch screen is the light pen

500) F2 keys of control center specified below displays data, toggles browse/edit
