Note: Answer all questions. Kindly note
that answers for 10 marks questions should be approximately of 400 words. Each
question is followed by evaluation scheme.
1. What is the difference between process and thread?
Answer : A process is an
executing instance of an application. What does that mean? Well, for example,
when you double-click the Microsoft Word icon, you start a process that runs
Word. A thread is a path of execution within a process. Also, a process can
contain multiple threads. When you start Word, the operating system creates a
process and begins executing the primary thread of that process.
Q. 2. Explain the any five types of
addressing modes.
Answer:To reference a large range of
locations in main memory, a variety of addressing technique are used. The
common addressing modes are:
·
Immediate
·
Direct
·
Indirect
Q. 3. Describe the logical layout of both
RISC and CISC computers
Answer:A computer with a large number
of instructions is classified as a complex instruction set computer,
abbreviated CISC. In the early 1980s, a number of computer designers
recommended that computers use fewer instructions with simple constructs so
they can be executed much faster within the CPU without having to use memory
as often. This type of computer is classified as a reduced instruction set
computer or RISC. In this section we introduce the major characteristics of
CISC and RISC architectures and then present the
Q. 4. Explain the concept of branch
handling. What is delayed branching?
Answer:The recent process of
globalization and its development hit all the nations of the world for their
rapid development of trade, commerce and industries. Branch, therefore, is the
result of rapid growth of business in the world. Since, there is an
international access to the trade and commerce, business undertakings are
opening their establishment nationally and internationally in the different
parts of the world. Whatever the business undertaking opened by the
organization, they are normally a segment of the original business undertaking
Q. 5. Explain any five types of vector
instructions in detail.
Answer:In computing, a vector processor
or array processor is a central processing unit (CPU) that implements an
instruction set containing instructions that operate on one-dimensional arrays
of data called vectors. (Compare scalar processors, whose instructions operate
on single data items.) Vector processors can greatly improve performance on
certain workloads, notably numerical simulation and similar tasks. Vector
machines appeared in the early 1970s and dominated supercomputer design through
the 1970s into the 1990s, notably the various Cray platforms. The rapid fall in
the price-to-performance ratio of
Q. 6. Write short notes on:
a) UMA:Uniform memory access (UMA) is a
shared memory architecture used in parallel computers. All the processors in
the UMA model share the physical memory uniformly. In a UMA architecture,
access time to a memory location is independent of which processor makes the
request or which memory chip contains the
b) NUMA: NUMA is an alternative
approach that links several small, cost-effective nodes using a
high-performance connection. Each node contains processors and memory, much
like a small SMP system. However, an advanced memory controller allows a node
to use memory on all other nodes, creating a single system image.
Non-uniform
memory access (NUMA) is a
