SEMESTER 2
SUBJECT CODE & NAME BT0068, Computer Organizationand Architecture
BK ID B0952
CREDIT & MARKS 4 CREDITS & 60 MARKS
Note:Answer all questions.Each questionisfollowedby evaluationscheme.
1 Explainvarious units of a digital computer with the helpof a diagram.
Answer: A computer can process data, pictures, sound and graphics. They can solve highly complicated
problems quickly and accurately. A computer as shown in Fig. performs basically five major computer
operationsorfunctionsirrespectiveof theirsize andmake.These are
1) it acceptsdata or instructionsbywayof input,
2) it storesdata,
2. What do you mean by bus in computersystem?Explain the busstructure.
Answer: A bus is a collection of wires that connect several devices within a computer system. When a
word of data is transferred between units, all its bits are transferred in parallel. A computer must have
some linesforaddressingandcontrol purposes.
Three main groupings of lines:

2. 3. Explainthe simple instructionformat with diagram and examples.
Answer: Computerinstructionsare the basiccomponentsof amachine language program.Theyare
alsoknownas macrooperations,since eachone iscomprisedof asequencesof microoperations.
Each instructioninitiatesasequence of microoperationsthatfetchoperandsfromregistersormemory,
possiblyperformarithmetic,logic,orshiftoperations,andstore resultsinregistersormemory.
Instructionsare encodedasbinary instruction codes.Each
4. Explainmemory interleavingwiththe helpof a diagram.
Answer: In computers, interleaving is a method of writing and reading data out of sequence. Data
interleaving is used to combine multiple digital data streams, like in files that contain both audio and
video. This technique is also used for memory interleave in disk storage and computer memory, used to
make data read and write more quickly. A de-interleaver uses mapping to decipher the interleaved data;
it ismore or lessa diagramof the interleavedpattern
5. Explaininterrupt and interruptdriven I/O.
Answer: An interrupt is a signal from a device attached to a computer or from a program within the
computer that causes the main program that operates the computer (the operating system ) to stop and
figure out what to do next. Almost all personal (or larger) computers today are interrupt-driven - that is,
they start down the list of computer instruction s in one program (perhaps an application such as a word
processor) and keep running the instructions until either (A) they can't go any further or (B) an interrupt
signal is sensed. After the interrupt signal is sensed, the computer either resumes running the program
it wasrunningor beginsrunninganotherprogram.

3. 6. ExplainDMA controller withthe helpof diagram.
Answer: The controller for a device employing DMA must have the capability of generating address
signals for the memory, as well as all of the memory control signals. The processor informs the DMA
controller that data is available (or is to be placed into) a block of memory locations starting at a certain
addressinmemory.The controllerisalsoinformedof the lengthof the datablock.
