Current paper with solution
What function is performed by the reset operation of a processor? What are the
two types of reset operations?
Answer:
Reset operation is required to change the processor‘s state to a known, defined value.
The two essential features of a reset instruction are clearing the control step counter and
reloading the PC to a predefined value.
Hard Reset
The SRC performs a hard reset upon receiving a start (Strt) signal. This initializes the PC
and the general registers.
Soft Reset
The SRC performs a soft reset upon receiving a reset (rst) signal. The soft reset results in
initialization of PC only.
Q2 What do you know about Hard disk.
Solution A hard disk drive (HDD; also hard drive, hard disk, or disk drive)[2] is a device
for storing and retrieving digital information, primarily computer data. It consists of one
or more rigid (hence "hard") rapidly rotating discs (often referred to as platters), coated
with magnetic material and with magnetic heads arranged to write data to the surfaces
and read it from them.
Hard drives are classified as non-volatile, random access, digital, magnetic, data storage
devices. Introduced by IBM in 1956, hard disk drives have decreased in cost and physical
size over the years while dramatically increasing in capacity and speed.
Hard disk drives have been the dominant device for secondary storage of data in general
purpose computers since the early 1960s.[3] They have maintained this position because
advances in their recording capacity, cost, reliability, and speed have kept pace with the
requirements for secondary storage.[3]
Q 3
(0.23) 10 convert in base 2
Question no 4 What is meant by Packet switching
Ans lecture no 34 …(page no360)
Qusetion no 6
Classification of fiber optics mode multimode and mono mode?
Solution
Multimode…… this fiber has large diameter when light is injected,it is disperses,so the effective data rate is dicreses.
Mono mode
Its diameter is very small.So dispersion ios small and data rate is very high.
Question no 7
Considered a 64kb direct maped catch with a line length of 32bytes
a determine the number of bits in the address that refer to the byte withen a cache line.
b determine the number of bits in the address required to select the cache line.
Solution (lecture no 41 ) page 348 o
Question no 8
If a DRAM has 512 rows and its fresh time is 9ms .What shoul be the frequency of rowrefresh operation on the average?
Solution
Refresh time =9ms
Number of rows =512
Therefore we have to do 512 rows refresh operation in 9ms interval.in other words one rowrefresh operation every( 9*10-³)/512=1.76*10 second
