Hello sir I am preparing for the NET exam so please provide me the previous year’s paper of computer science subject.

The National Educational Testing Bureau of University Grants Commission (UGC) conducts National Eligibility Test (NET) for appointment of Lecturers in colleges and universities and for award of Junior Research Fellowship (JRF).

Computer Science NET Paper

1. For the 8-bit word 00111001, the check bits stored with it would be 0111. Suppose when the word is read from memory, the check bits are calculated to be 1101.What is the data word that was read from memory?

B. 00011001
C. 00111000
D. 11000110

2. Consider a 32 - bit microprocessor, with a 16 - bit external data bus, driven by an 8 MHz input clock. Assume that the microprocessor has a bus cycle whose minimum duration equals four input clock cycles. What is maximum data transfer rate for this microprocessor ?
A. 8 x 106 bytes / sec
B. 4 x 106 bytes / sec
C. 16 x 106 bytes / sec
D. 4 x 109 bytes / sec

3. The RST 7 instruction in 8085 microprocessor is equivalent to

5. The CPU of a system having 1 MIPS execution rate needs 4 machine cycles on an average for executing an instruction. The fifty percent of the cycles use memory bus. A memory read/write employs one machine cycle. For execution of the programs, the system utilizes 90 percent of the CPU time. For block data transfer, an IO device is attached to the system while CPU executes the background programs continuously. What is the maximum IO data transfer rate if programmed IO data transfer technique is used?

7. Let E1 and E2 be two entities in E-R diagram with simple single valued attributes. R1 and R2 are two relationships between E1 and E2 where R1 is one-many and R2 is many - many. R1 and R2 donot have any attributes of their own. How many minimum number of tables are required to represent this situation in the relational model ?
A. 4
B. 3
C. 2
D. 1

8. The student information in a university is stored in the relation STUDENT (name, sex, marks, dept_Name) Consider the following SQL query select deptName from STUDENT where sex = 'M' group by dept_Name having avg (marks) > (select avg (marks) from STUDENT) It returns the names of the department in which
