Computer Peripheral Devices Quiz

Computer Peripheral Devices

• A CPU is not a peripheral device. Peripherals are devices that work alongside the central processing unit (CPU).

• A keyboard, monitor, and mouse are considered peripheral devices.

System Unit Port

• A port is a connection point in a system unit that allows data transfer between various devices and the computer.

Read-Only Memory (ROM)

• ROM is a computer memory where users cannot write new information or instructions.

Group of 8 Bits

• A group of 8 bits is called a byte.

Megabyte Equivalence

• A megabyte (MB) is equivalent to 1024 * 1024 bytes.

Device Drivers

• Device drivers enable input/output (I/O) devices to communicate with the computer system.

Types of Computer Memory

• The two main types of computer memory are primary and secondary memory.

Non-Erasable Audio Storage

• A CD is a non-erasable disk used for storing digitized audio information.

Computer Output/Outputting

• Outputting is the process of producing useful information for the user.

Output Unit Function

• The output unit converts user-readable data to a computer-readable format. This is not a function of output.

Smallest Unit of Data

• The smallest unit of data in a computer is a bit.

Input Unit Function

• An input unit reads instructions and data from the outside world. It does not convert data into a user-friendly format for use.

Raw Material of Data Processing

• The raw material used in data processing is data and information.

Computer Characteristics

• A computer characteristic is not IQ. Characteristics include speed, accuracy, and capacity.

Memory Definition

• Memory is any electronic place to store data for later retrieval, not just computer memory.

Memory Size

• The size of main memory depends on the size of the address bus.

Address Bus Independence

• Secondary memory is independent of the address bus.

MAR Definition

• MAR stands for Memory Address Register.

Optical Disks and Storage

• Optical disks are a valuable medium for high-capacity secondary storage.

Optical Disk Technology

• Laser beam technology is used in optical disks.

Optical Disk Capacity

• The capacity of an optical disk is calculated by multiplying the number of sectors by the number of bytes per sector.

Disk Rotation and Radius

• The rotation of a disk varies inversely with the radius of the disk.

Sector Size in Tracks

• The size of sectors in tracks remains the same.

Optical Disk Access Time

• The typical access time for optical disks is 100-300 milliseconds.

Laser Beam Technology Use

• DVDs use laser beam technology.

Bar Code Reader Type

• A bar code reader is an input device.

Computer for Television Interaction

• A supercomputer can interact with a television set.

Fundamental Computer Characteristics

• High cost is not a fundamental characteristic of a computer; reliability, speed, and storage capability are characteristics.

Computer Classification

• A maxicomputer is not a standard computer classification.

Non-Professional Computer Users

• Non-professional computer users are often called end-users.

Most Powerful Computers

• Supercomputers are the most powerful computers.

Kilobyte Definition

• A kilobyte (KB) is 1024 bytes.

Memory Allocation Process

• Memory management is the process of allocating main memory to programs and separating them.

Primary Storage Alternative Name

• The primary storage unit is also called memory.

Memory Type

• QRAM is not a type of memory.

Logic Chip Alternative Name

• Another name for a logic chip is a microprocessor.

Data Representation on Computers

• Data on computers is represented by the binary system.

Data Symbol Representation

• A letter, digit, or special character is represented by a bit.

Memory Capacity Units

• Memory capacity can be measured in megabytes.

Cache Location

• Cache is built into the CPU chip (L1 cache).

Processor Speed Measurement

• Processor speed for personal computers is measured in megahertz (MHz).

Screen Pixel Distance

• The distance between pixels on a screen is called dot pitch.

Screen Symbol

• A pictorial symbol on a screen that represents computer activity is called an icon..

Soft Copy Image Display

• A soft copy of an image is displayed on the computer screen.

Optical Character Recognition Device

• A wand reader is an optical character recognition device.

Another Term for Mark Sensing

• Mark sensing is also known as OMR (Optical Mark Recognition).

Screen Refresh Rate

• The rate of screen refreshment is called raster rate.
