Computer Architecture refers to the basic designing of the different parts of a computer to create the right combination of hardware components and systems in order to make the whole computer unit cost effective. In a world where the computer is an indispensible object, this course of study is really effective and useful in familiarising students with the whole art of creating computer units that are affordable and useful at the same time. Some of the topics that students get to study under the discipline of this course are clock sequential circuit, programmable device, cycle stealing technique, direct mapping technique, excitation table, different methods used for representing signed number, classification of computers based on instruction format, salient features of Asynchronous and Synchronous serial data transfer techniques, working of content addressable memory unit, page fault and page replacement policies, FIFO Buffer, Micro program sequence, micro instruction formats, main features of associative memory. While going through this paper you will find 10 Multiple choice questions which is compulsory and holds 20 marks (2 marks *10) and 8 long questions and 5 to be answered (16 marks * 5). Below are attached some of the previous year’s question papers for your help.
