Computer Components and Functions Quiz

Computer Components and Functions

• Peripheral Devices: The CPU is not a peripheral device. Peripherals are external devices that work with the computer.
• Data Transfer: Ports allow data transfer between devices and the computer system.
• Read-Only Memory (ROM): ROM is memory where users cannot write new information or instructions. It holds essential startup programs.
• Byte: A group of 8 bits forms a byte.
• Megabyte Conversion: 1 Megabyte equals 1,000,000 bytes.
• Device Drivers: Device drivers allow input/output devices to connect to the computer system.
• Memory Types: The two basic memory types are primary and secondary.
• CD-ROMs: A non-erasable disk that stores digitized audio is a CD.
• Outputting: Creating useful information for the user is outputting.
• Plotters: Plotters produce images or drawings.
• Drum Printers: Line printers that print one line at a time are drum printers.
• CRT Monitors: CRT monitors are traditional, television-like monitors often used with non-portable computers.
• Output Unit Function: Output units display data in a user-friendly format. They do not supply data and instructions to the computer for further processing.
• Bit: The smallest unit of data in a computer is a bit.
• Input Unit Function: Input units provide data to the computer for processing. They do not convert data into a user-friendly format.
• Data and Information: Data is raw input and information is processed data that is useful to a user.
• Computer Characteristics: A computer's characteristics do not include IQ.
• Memory and Address Bus: The size of main memory is influenced by the size of the address bus.
• Memory Address Register (MAR): MAR stands for Memory Address Register.
• Optical Disks: Optical disks use laser beams for data storage.
• Address Bus Independence: Secondary memory is independent of the address bus.
• Optical Disk Types: Winchester is not an optical disk type.
• Input Devices: Bar code readers are input devices.
• Primary Storage: Another name for memory (primary storage) is memory.
• End-Users: Computer users who are not professionals are end-users.
• Supercomputers: Supercomputers are the most powerful computers.
• Logic Chip Equivalent: A logic chip is a microprocessor.
• Data Representation: Binary is the two-state (on/off) system that represents data on a computer.
• Processor Speed: Processor speeds are measured in gigahertz (GHz).
• Soft Copy: Soft copy refers to screen output (visual display on a screen).
• Non-impact Printers: Inkjet printers are non-impact printers.
• OMR: "Mark sensing" is another name for OMR. OMR translates markings into machine-readable data.
• Office Suite Applications: Antivirus software is not typically included in an office suite.
• Adobe Acrobat File Format: Adobe Acrobat files are stored in PDF (Portable Document Format) format.
• Booting: Loading the operating system is booting the computer.
• Operating System Examples: MS Access is not an operating system. Examples are Windows, macOS, Linux.
• Cache Memory: L1 cache memory is built into the CPU chip.
• Register Length: The length of a register is the word size.
• Uniform Resource Locator (URL): A URL represents a website's address.
• Top-Level Domain: The most commonly used top-level domain is .com.
• Collaborative Software: Collaborative software is also known as groupware.
• Scrolling: Scrolling moves pages up or down on a screen.
• Motherboard: The main circuit board in a computer is the motherboard.

Memory and Storage

• Primary Storage: Primary storage is also known as memory.
• Types of Memory: QRAM is not a memory type. Examples are RAM, ROM, cache memory.
• Memory Types: Primary storage, secondary storage.

Additional Concepts

• Output Units: Output units present information in a usable format.
• Input Units: Input units gather data from the user.
• Data Processing: The process of converting data into usable information is called data processing.
• Computer Purpose: Computers process data and produce useful information for people using a variety of programs, applications, and hardware.
