Question 1

The physical components of a computer are referred to as ____.
A) software
B) hardware
C) configurations
D) specifications

Accepted Answer

Hardware includes all physical components of a computer, such as the central processing unit (CPU), memory, hard drive, motherboard, etc. Software refers to programs and applications that run on the hardware. Configurations and specifications can be related to both hardware and software, but do not encompass all physical components of a computer.

Question 2

A file that tells a computer how to perform a specific task is called a(n) ____ file.
A) executable
B) instruction
C) data
D) configuration

Accepted Answer

An executable file is a type of file that contains instructions for the computer to perform a specific task. It can be run or executed by the computer to perform the task it was designed for. Instruction files, data files, and configuration files, while important, do not contain instructions for the computer to perform a specific task.

Question 3

A hard copy of a file you created on your computer would be ____.
A) saved on a floppy disk
B) printed on a printer
C) backed up on a tape drive
D) sent as an e-mail

Accepted Answer

Printing a file on a printer creates a physical hard copy of the file. The other options do not result in a hard copy.

Question 4

Which of the following is NOT shown in the figure above?
A) keyboard
B) mouse
C) touch pad
D) trackball

Accepted Answer

The answer of    Which of the following...

Question 5

Another name for the CPU pictured above is ____.
A) microprocessor
B) RAM cache
C) clock speed
D) megahertz

Accepted Answer

The pictured component is a microprocessor, which is also commonly referred to as a CPU (central processing unit). RAM cache, clock speed, and megahertz are all related to the operation of the CPU, but do not represent alternative names for the component itself.

Question 6

An example of an output device is a ____.
A) keyboard
B) monitor
C) mouse
D) touch pad

Accepted Answer

A monitor is an example of an output device as it displays visual information from the computer to the user. Keyboards, mice, and touch pads are all input devices as they allow the user to input information into the computer.

Question 7

Special high-speed memory reserved for the microprocessor's use is called ____.
A) ROM
B) storage
C) virtual memory
D) cache memory

Accepted Answer

Cache memory is a special high-speed memory reserved for the microprocessor's use. It is designed to improve the speed at which the processor can access data from the main memory. It stores frequently used data and instructions closer to the processor, allowing for faster access and execution. ROM is Read-Only Memory and is used for permanent storage of system software. Storage refers to any device or mechanism that is used to store data, including hard drives and flash drives. Virtual memory is a memory management technique that allows the operating system to use a part of the hard drive as auxiliary memory when the RAM is full.

Question 8

Megahertz is a measurement of ____.
A) the amount of memory
B) the amount of RAM
C) the speed of the microprocessor
D) cache memory

Accepted Answer

Megahertz (MHz) is a measurement of the clock speed of a microprocessor, indicating how many cycles per second it can execute. It is not a measurement of memory, RAM, or cache memory.

Question 9

Where is program and data that is being used temporarily stored by your computer?
A) cache
B) RAM
C) ROM
D) CMOS

Accepted Answer

The data and program being used temporarily are stored in Random Access Memory (RAM), which is a type of volatile memory that only retains data while the computer is turned on. The cache is a smaller and faster form of memory that stores frequently accessed data for quicker access. ROM (Read-Only Memory) is a type of non-volatile memory that stores permanent data and instructions, while CMOS (Complementary Metal-Oxide-Semiconductor) is a type of memory used for system settings and configuration.

Question 10

Processing tasks occur on the ____.
A) motherboard
B) keyboard
C) control panel
D) operating system

Accepted Answer

Processing tasks occur on the motherboard, which contains the CPU and other components that work together to process data and perform calculations. The keyboard and control panel are input devices, and the operating system manages the overall operation of the computer but does not directly perform processing tasks.

Question 11

The speed of a laser printer is measured in ____.
A) pages per minute
B) pages per second
C) characters per minute
D) characters per second

Accepted Answer

Laser printers are typically measured in pages per minute (ppm), as they print entire pages at a time rather than individual characters.

Question 12

Personal computers commonly use the ____ code system to represent character data.
A) KB
B) LAN
C) ASCII
D) COBOL

Accepted Answer

ASCII (American Standard Code for Information Interchange) is the most commonly used code system to represent character data in personal computers. It uses a 7-bit binary code to represent 128 different characters including letters, numbers, and symbols.

Question 13

The computer needs additional components called ____ to accomplish its input, output, and storage functions.
A) mice
B) specifications
C) architecture
D) peripheral devices

Accepted Answer

Peripheral devices are the additional components that a computer needs to accomplish its input, output, and storage functions. Mice and specifications are not necessarily required components and architecture refers to the design and organization of the computer's internal components rather than external peripherals.

Question 14

Which of the following dot pitches gives you the sharpest picture?
A) .26
B) .32
C) .38
D) .45

Accepted Answer

The lower the dot pitch, the sharper the picture. Therefore, the dot pitch of .26 would give the sharpest picture out of the options given.

Question 15

Resolution is the ____.
A) number of pixels a monitor displays
B) distance between pixels in a graphics display
C) number of rectangles in a character-based display grid
D) dot pitch in a graphics display

Accepted Answer

Resolution is the number of pixels a monitor displays.

Question 16

You are running two programs at once that require 8 megabytes each on a computer that only has 12 megabytes of RAM. What makes this possible?
A) virtual memory
B) ROM
C) cache
D) CMOS

Accepted Answer

This is possible due to virtual memory. Virtual memory allows the computer to use a portion of the hard drive as if it were extra RAM, allowing multiple programs to run simultaneously even if there is not enough physical RAM available.

Question 17

The devices shown in the figure above are all ____ devices.
A) input
B) pointing

Question 19

Which of the following is NOT a personal computer?
A) desktop
B) laptop
C) notebook
D) mainframe

Accepted Answer

Desktop, laptop, and notebook are all types of personal computers designed for individual use. Mainframe, on the other hand, is a large computer system designed for centralized data processing and used by organizations or corporations.

Question 20

Which of the following is a personal computer?
A) desktop
B) mainframe
C) terminal
