Question 5

When the computer is turned off, the contents of ____________ are erased.
A) secondary storage
B) RAM
C) software
D) hardware

Accepted Answer

When the computer is turned off, the contents of RAM (Random Access Memory) are erased. This is because RAM is a type of volatile memory, meaning it requires a constant flow of electricity to maintain its data. Once the power is turned off, the data stored in RAM is lost. Secondary storage, such as hard drives or solid-state drives, retains data even when the computer is turned off. Software is a collection of programs and data that can be stored in either RAM or secondary storage, but turning off the computer will not erase the software itself. Hardware refers to the physical components of the computer, such as the motherboard or CPU, and is not directly affected by turning off the computer.

A) RAM
B) Secondary storage
C) Application software
D) Main memory

Accepted Answer

Secondary storage includes devices such as hard disk drives, solid-state drives, and optical discs, which can hold data for long periods of time even when there is no power to the computer. RAM (A) and main memory (D) are volatile and require power to retain data. Application software (C) refers to programs that are installed on the computer for specific tasks and does not relate to memory storage.

Question 7

The ____________ is the part of a computer that actually runs programs.
A) CPU
B) software
C) main memory
D) programming language

Accepted Answer

The CPU, or Central Processing Unit, is the part of the computer that executes instructions of a program. It is responsible for performing arithmetic and logic operations, controlling the flow of data, and communicating with other parts of the computer. Software, main memory, and programming languages are all important components of a computer, but they do not directly run programs like the CPU does.

Question 8

Data produced by the computer is sent to a(n) ____________, which formats and presents it.
A) input device
B) output device
C) storage device
D) program

Accepted Answer

Output devices receive data from the computer and present it in a human-readable format. Input devices, on the other hand, allow data to be entered into the computer. Storage devices save data for later use, and programs are sets of instructions that tell the computer what to do with the data.

Question 9

Question 10

A(n) ____________ stores data by magnetically encoding it onto a circular disk.
A) CPU
B) output device
C) program
D) disk drive

Accepted Answer

The definition given in the question perfectly matches with a disk drive. A CPU is the central processing unit which carries out calculations and operations, an output device is used to display or present data, and a program is a set of instructions for the computer to follow. None of these involve magnetically encoding data onto a circular disk.

Question 11

The component that collects the data and sends it to the computer is called a(n) ____________.
A) storage device
B) output device
C) sending unit
D) input device

Accepted Answer

The component that collects the data and sends it to the computer is called an input device. Input devices include things like keyboards, mice, scanners, and cameras, which allow users to input data into a computer for processing. Output devices, on the other hand, display or output data from the computer, while storage devices are used to store data for later retrieval. Sending unit is not commonly used terminology in computing.

Question 12

A ____________ records data onto a small floppy disk, which can be removed from the drive.
A) USB drive
B) hard drive
C) floppy disk drive
D) DVD

Accepted Answer

The statement specifically mentions a "small floppy disk" and a "drive" from which it can be removed. The only option that fits this description is a floppy disk drive, as USB drives, hard drives, and DVDs are not typically associated with removable floppy disks.

Question 13

____________ is any data the computer collects from people and from other devices.
A) Telemetry
B) Input
C) Information
D) Storage

Accepted Answer
