Directions to Solve

In the following questions choose the word which is the exact OPPOSITE of the given words.

Q1: LEND

A Cheat

B Hire

C Borrow

D Pawn

Q2: scanf() or atoi() function can be used to convert a string like "436" in to integer.

A Yes

B No

Q3: A 64-Mbyte SIMM is installed into a system, but when a memory test is executed, the SIMM is detected as a 32-Mbyte device. What is a possible cause?

A The most significant address line is stuck high or low.

B The address decoder on the SIMM is faulty.

C The voltage on the memory module is incorrect.

D The memory module was not installed properly.

Q4:
Refer the given figure. The outputs (Q0–Q3) of the memory are always LOW. The address lines (A0–A7) are checked with a logic probe and all are indicating pulse activity, except for A3, which shows a constant HIGH, and A7, which shows a constant LOW; the select lines, are checked and shows pulse activity, while indicates a constant HIGH. What is wrong, and how can the memory be tested to determine whether it is defective or if the external circuitry is defective?

A The output buffers are probably defective since they are all tied together; the common input line is most likely stuck LOW. Change the output buffer IC.

B One of the inputs to the active-LOW select AND gate may be stuck high for some reason; take both select lines LOW and check for pulse activity on the outputs, Q0–Q3. If the outputs now respond, the problem is most likely in the program or circuitry driving the select lines.

C Since no data appears to be getting through to the output buffers, the problem may be in the X decoder; change the X decoder IC.

D The problem appears to be in the two address lines that never change levels; the problem is probably in the program driving the memory address bus.

Q5: How many address lines would be required for a 2K × 4 memory chip?

A 12

B 11

C 10

D 8

Q6: Which type of ROM has to be custom built by the factory?

A EEPROM

B ROM

C mask ROM

D EPROM

Q7: What is the computer main memory?

A RAM and ROM

B CD-ROM and hard drive

C CMOS and hard drive

D Hard drive and RAM

Q8: A major disadvantage of the mask ROM is that it:

A is very expensive to change the stored data when system requirements change

B is time consuming to change the stored data when system requirements change

C has an extremely short life expectancy and requires frequent replacement

D cannot be reprogrammed if stored data needs to be changed

Q9: The periodic recharging of DRAM memory cells is called ________.

A refreshing

B multiplexing

C flashing

D bootstrapping

Q10: Which of the following is normally used to initialize a computer system's hardware?

A Static memory

B External mass memory

C Volatile memory

D Bootstrap memory
