computation
- (C) Is
a method of allocating processor time
- (D) Allows
multiple programs to reside in separate areas of core at the time
2. The table created by lexical analysis to describe all literals used in the source program, is

table
- (B) Literal
table

table

a hardware memory device which denotes the location of the current instruction
being executed

a group of electrical circuits (hardware), that performs the intent of
instructions fetched from memory
- (C) Contains
the address of the memory location that is to be read from or stored into
- (D) Contains a
copy of the designated memory location specified by the MAR after a
"read" or the new contents of the memory prior to a "write"
4. The computational technique used to compute the disk storage address of individual records is called:
- (A) Bubble
memory
- (B) Key
fielding
- (C) Dynamic
reallocation

6. Thrashing
- (A) Is
a natural consequence of virtual memory systems
- (B) Can
always be avoided by swapping
- (C) Always
occurs on large computers
- (D) Can
be caused by poor paging algorithms
7. The advantage(s) of incorporating the macro processor into pass 1 is(are):
- (A) Many
functions do not have to be implemented twice
- (B) Functions
are combined and it is not necessary to create intermediate files as output
from the macros processor and input to the assembler

flexibility is available to the programmer in that he may use all the features
of the assembler in conjunction with macros

of the above

publishing
11. Virtual Memory
- (A) Is a method
of memory allocation by which the program is subdivided into equal portions, or
pages and core is subdivided into equal portions or blocks
- (B) Consists

computation
- (C) Is
a method of allocating processor time
- (D) Allows

13. Round-robin scheduling
- (A) Allows
interactive tasks quicker access to the processor
- (B) Is
quite complex to implement
- (C) Gives
each task the same chance at the processor
