A
Correct answer
Explanation
Computer program is a sequence of instructions that tells a computer what to do.
-
Mnemonic
-
Bar code
-
Decoder
-
Instruction
-
None of these
A
Correct answer
Explanation
Mnemonic is a term, symbol or name that is used to specify a computing function.
-
utility
-
browser
-
database
-
spreadsheet
-
None of these
C
Correct answer
Explanation
Database is the correct answer.
-
an assembler
-
a linker
-
a loader
-
a compiler
C
Correct answer
Explanation
A loader is a system program that loads executable programs from secondary storage into main memory and prepares them for execution. It allocates memory, relocates addresses, and initializes the program. Assemblers convert assembly code to machine code, linkers combine object files, and compilers translate high-level code to machine code.
-
Trap door
-
Logic bomb
-
Trojan horse
-
Stack and buffer overflow
-
None of the above
E
Correct answer
Explanation
All of the above are called program threats.
-
program
-
data
-
control
-
none of these
C
Correct answer
Explanation
The header of a packet contains control information that is used by network devices to manage the delivery and processing of the data. This includes metadata such as source and destination addresses, protocol versions, and error-checking codes. The actual user data or program content is contained in the payload section of the packet, not the header.
-
Floating Point
-
Megaflops
-
Nan flops
-
Speed
B
Correct answer
Explanation
Megaflops stands for Million Floating-point Operations Per Second. It is a specific unit used to measure the computational performance of a processor, particularly for floating-point arithmetic.
C
Correct answer
Explanation
Memory is the general term for the hardware where data is stored in a computer. While RAM and ROM are specific types of memory, the term 'Memory' correctly identifies the storage location in a broad sense.
-
MIP
-
Seconds
-
Instructions per second
-
m/s
A
Correct answer
Explanation
MIPS (Millions of Instructions Per Second) is a measure of a computer's processing speed. Although 'MIP' is likely a typo for MIPS, it is the standard unit used for this measurement in computing.
B
Correct answer
Explanation
ROM (Read-Only Memory) is non-volatile and contains instructions that are permanently written during manufacture. Neither the user nor the computer's standard software can modify this information, meaning they have no control over it.
-
CISC Processors
-
RISC Processors
-
EPIC Processors
-
None of these
B
Correct answer
Explanation
ALPHA, RIOS, and SPARC are all examples of Reduced Instruction Set Computer (RISC) architectures. These processors use a simplified set of instructions to achieve higher performance and efficiency.
-
A Power fire virus
-
Old junk computers of no use
-
A processor with high capacity
-
None of these
-
a flat cable from the disk controller card to disk drive
-
a small initialisation program to start up the computer
-
additional memory device
-
a flat cable connecting the CPU to the printer
B
Correct answer
Explanation
A bootstrap is a small program that resides in the computer's ROM and is executed when the system is powered on. Its primary function is to locate and load the operating system into the RAM to start the computer's operation. This process is commonly known as booting the system.
-
Disk operating system
-
Ram operating system
-
Alphanumeric
-
Random-access Memory
A
Correct answer
Explanation
A Disk Operating System (DOS) is a type of system software that manages the computer's hardware and provides services for execution of applications. Its primary focus is managing files and data flow to and from disk storage devices. Other options like RAM or Alphanumeric do not describe a type of operating system.
