SUMMER-2015 ASSIGNMENT
PROGRAM MCA(REVISED FALL 2012)
SEMESTER SECOND
SUBJECT CODE & NAME MCA2050- COMPUTER ARCHITECTURE
CREDITS 4
BK ID B1648
MARKS 60
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
youstart Word, the operatingsystemcreates a process and begins executing the primary thread of
that process.
Q. 2. Explain the any five types of addressing modes.
Answer:Toreference 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

2. Answer:A computer with a large number of in-structions is classified as a complex instruction set
computer,abbreviatedCISC.Inthe early1980s, a numberof computerdesignersrecommendedthat
computers use fewer instructions with simple constructs so they can be exe-cuted 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 architec-tures and then present the
Q. 4. Explain the concept of branch handling. What is delayed branching?
Answer:The recentprocessof globalizationand its development hit all the nations of the world for
theirrapiddevelopmentof trade,commerce andindustries. Branch,therefore, is the result of rapid
growthof businessinthe world.Since, there is an international access to the trade and commerce,
businessundertakingsare openingtheirestablishmentnationallyandinternationallyinthe 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:Uniformmemoryaccess(UMA) is a sharedmemoryarchitecture usedinparallelcomputers.
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,anadvancedmemorycontrollerallowsanode to use memory on all other nodes,
creating a single system image.
Non-uniform memory access (NUMA) is a
