1. The ______ format is usually used to store data.
a) BCD
b) Decimal
c) Hexadecimal
d) Octal
Explanation: The data usually used by computers have to be stored and represented in a particular format for ease of use.
2. The 8-bit encoding format used to store data in a computer is ______
a) ASCII
b) EBCDIC
c) ANCI
d) USCII
Explanation: The data to be stored in the computers have to be encoded in a particular way so as to provide secure processing of the data.
3. A source program is usually in _______
a) Assembly language
b) Machine level language
c) High-level language
d) Natural language
Explanation: The program written and before being compiled or assembled is called as a source program.
4. Which memory device is generally made of semiconductors?
a) RAM
b) Hard-disk
c) Floppy disk
d) Cd disk
Explanation: Memory devices are usually made of semiconductors for faster manipulation of the contents.
5. The small extremely fast, RAM’s are called as _______
a) Cache
b) Heaps
c) Accumulators
d) Stacks
Explanation: These small and fast memory devices are compared to RAM because they optimize the performance of the system and they only keep files which are required by the current process in them
6. The ALU makes use of _______ to store the intermediate results.
a) Accumulators
b) Registers
c) Heap
d) Stack
Explanation: The ALU is the computational center of the CPU. It performs all mathematical and logical operations. In order to perform better, it uses some internal memory spaces to store immediate results.
7. The control unit controls other units by generating ___________
a) Control signals
b) Timing signals
c) Transfer signals
d) Command Signals
Explanation: This unit is used to control and coordinate between the various parts and components of the CPU.
8. ______ are numbers and encoded characters, generally used as operands.
a) Input
b) Data
c) Information
d) Stored Values
Explanation: Data
9. The Input devices can send information to the processor.
a) When the SIN status flag is set
b) When the data arrives regardless of the SIN flag
c) Neither of the cases
d) Either of the cases
Explanation: The input devices use buffers to store the data received and when the buffer has some data it sends it to the processor.
10. ______ bus structure is usually used to connect I/O devices.
a) Single bus
b) Multiple bus
c) Star bus
d) Rambus
Explanation: BUS is a bunch of wires which carry address, control signals and data. It is used to connect various components of the computer.
