An error in computer data is called a bug. A bug is an unexpected problem with software or hardware. Typical problems are often the result of external interference with the program’s performance that was not anticipated by the developer.
72. The silicon chips used for data processing are called
ram chips
rom chips
microprocessors
prom chips
Answer:3. microprocessors
Explanation:
The silicon chips used for data processing are called Micro processor
When the CPU is implemented on a single, wafer-thin tiny silicon chip, then it is called a microprocessor or microchip. The chip would contain the control unit, the ALU, and the more advanced designs may have the memory, and interfaces for input-output devices. Because of this, the microprocessor is known as “a computer on a chip”.
73. The instructions for starting the computer are house on
random access memory
cd-rom
read-only memory chip
all of above
Answer: 3. read-only memory chip
Explanation:
The instructions for starting the computer are housed on a read-only memory chip.
The difference between RAM and ROM is given below.
RAM
ROM
The full form is Random Access Memory
The full form is Read-Only Memory
It is a form of temporary memory where the memory content is lost if power is switched off
It is a form of permanent or non-volatile memory in which the contents are stored permanently.
It is used to form the working memory of the computer.
It is used to form the BIOS chip of the computer.
One can both read and write data to a RAM
One can only read the data from a ROM
74. The ALU of a computer normally contains a number of high-speed storage elements called
semiconductor memory
registers
hard disks
magnetic disk
Answer: 2. registers
Explanation:
The ALU of a computer normally contains a number of high-speed storage elements called registers.
A processor register (CPU register) is one of a small set of data holding places that are part of the computer processor. A register may hold an instruction, a storage address, or any kind of data (such as a bit sequence or individual characters). Some instructions specify registers as part of the instruction.
75. The first digital computer built with IC chips was known as
IBM 7090
apple – 1
IBM system / 360
vax-10
Answer: 3. IBM system / 360
Explanation:
The first digital computer built with IC chips was known as IBM system / 360. The IBM System/360 (S/360) is a family of mainframe computer systems that was announced by IBM on April 7, 1964, and delivered between 1965 and 1978.
76. Which of the following terms is the most closely related to main memory?
non-volatile
permanent
control unit
temporary
Answer: 4. Temporary
Explanation:
Temporary memory is the most closely related to main memory. RAM is a volatile memory. It provides temporary storage for data and instructions
77. Which of the following is used for manufacturing chips?
control bus
control unit
parity unit
semiconductor
Answer: 4. semiconductor
Explanation:
The semiconductor is used for manufacturing chips. To make wafers, silicon is purified, melted, and cooled to form an ingot, which is then sliced into discs called wafers. Chips are built simultaneously in a grid formation on the wafer surface in a fabrication facility or “fab.”
78. To locate a data item for storage is
field
feed
database
fetch
Answer: 4. fetch
Explanation:
To locate a data item for storage is called fetch.
Fetch is the first of two stages involved in computer processing. The processor operates by processing instructions in what is called the “fetch/execute cycle.”
79. A directly accessible appointment calendar is the feature of a _______ resident package.
CPU
memory
buffer
alu
Answer: 2. memory
Explanation:
A directly accessible appointment calendar is the feature of a memory-resident package.
A memory-resident program has the ability to stay in the computer’s memory after execution and to continuously run. Typically backdoors stay in memory to await commands, as do. file infectors to infect files as they are opened. Some worms stay in memory to continually send emails.
