COMPUTER SCIENCE 2004 Paper
FEDERAL PUBLIC SERVICE COMMISSION COMPETITIVE EXAMINATION FOR RECRUITMENT TO POSTS IN BPS – 17 UNDER THE FEDERAL GOVERNMENT, 2004. COMPUTER SCIENCE TIME ALLOWED: THREE HOURS MAXIMUM MARKS:100 NOTE:Attempt FIVE questions in all, including QUESTION No.8 which is COMPULSORY. Select at least ONE question from each of the SECTIONS-I, II and III. All, questions cany EQUAL marks. SECTION-I 1-(a) Explain the two strategic technologies to make the computer speedier; RISC and Parallel Processing. Hence also differentiate between RISC and CISC.(10) (b) Discuss the sequential, indexed and direct data organization. (10) 2-(a) Explain, shortly, different file management systems.(10) (b) Define and explain the Interleaved Processing Techniques. (10) 3-(a) Which are different tools to handle WAN traffic ? Explain them. (10) (b) What are communication protocols? Define Full Duplex and Synchronous Transmissions.(10) SECTION-II 4-(a) Suppose that a non-negat*'ve weight w(e) is associated with each edge in an undirected graph G = (V, E), give an efficient algorithm to find an acyclic subset of E of total maximum weight. (10) (b) How can the number of strongly connected components of a graph change if a new edge is added? (10) 5-(a) Differentiate between Object Oriented Programming and Procedural Programming. Also explain the concept of Abstraction in OOP. (10) (b) Data-flow diagrams are means of documenting end-to-end data flow through a system; SECTION-III 6-(a) What is the difference between a data entity in first normal form (Inf) and second normal from (2NF)? Give an example of an entity in INF and show its conversion to 2NF. (10) (b) List and briefly describe the three table operations used to manipulate relational tables. (10) 7-(a) What is Polygon Mesh Representation? Give at least two examples of polygon modeling strategies.(10) (b) What are the tools to develop web pages in dynamic contents? (10) COMPULSORY QUESTION (A) Write the terms, on your answer book, for whom the following abbreviations stand for: (5) (i) DML (ii) EDI (iii) OLE (iv) SDLS (v) RAID (5). (B) Please choose the most appropriate answer from the given set of options about all the following given statements. (5) (i) When all access and processing is done in one location, a computer system is said to be (a) networked (b) distributed (c) centralized (d) linked (ii) Tools to change PROM chips, called (a) chip kits (b) RAM burners (c) PROM burners (d) none of these (iii) The type of modulation that changes the height of the single is called (a) frequency (b) phase (c) amplitude (d) prophase (iv) A connection for similar network: (a) satellite (b) bridge (c) gateway (d) fax (v) The technology whereby part of the program is stored on disk and is brought into memory for execution as needed is called (a) memory allocation (b) virtual storage (c) interrupts (d) prioritized memory (C) Write '"True" or "False" in your answer book about the following statements: (5) (i) Application software may be either custom or packaged. (ii) RISC technology uses more instructions than traditional computers. (iii) A ring network has no central host computer. (iv) Satellites use line-of-sight transmission. (v) Time-sharing is both event-driven and time-driven. (D) Write short answer to the following: (5) (i) Modularity (ii) Teinet (iii) Cache Memory (iv) Applet (v) Function Overloading |

Thanx Adnan !
Being a Computer Professional , I would like to say some comments about the paper . First Of All , Its beyond the Bechlors Of Computer Engineering Standards . If you consider it in between bechlors , its very much tough One . We are forced to study selective cources in our universities . The part of the course i have studied is almost not visible . Ofcourse ONe would be knowing whats Object Oriented Programming and Procedural one but most of the questions are selected from those areas where even Lecturers and Professors dont bother to go for . My Personal Opinion is , this paper have shown me WHERE AM I |

Atleast some of the questions are what i also studied in Fsc like File Managment system,Full Duplex and Synchronus Transmission modes and Polygon Mesh Representation and some others too ,although not in high detail but atleast one can attempt,besides i'll better analyse myself when i am done with my bachelors
