• Bit: The smallest unit of data in a computer is a bit.
• Input Unit Function: The input unit receives data, it doesn't transform it into a user-friendly format.
• Data and Information: Data is raw input material; information is processed data.
• Computer Characteristics: A computer's I.Q. isn't a relevant characteristic.
• Main Memory and Address Bus: Main memory size is directly related to the address bus size.
• 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: A Winchester disk is not an optical disk type.
• Bar code reader: A bar code reader is an input device.
• Primary Storage: Another name for memory is primary storage.
• End-users: Non-computer professionals are considered end-users.
• Powerful Computers: Supercomputers are the most powerful computers.
• Primary Storage Synonyms: Primary storage is also called memory.
• Memory Types: QRAM is not a valid memory type.
• Logic Chips: A logic chip is also called a microprocessor.
• Binary System: Computers represent data using the binary system (0s and 1s).
• Processor Speed: Processor speed for high-end PCs is measured in gigahertz.
• Soft Copy: Soft copy refers to output displayed on a screen.
• Nonimpact Printers: Ink-jet printers are nonimpact printers.
• OMR: "Mark sensing" is another term for Optical Mark Recognition (OMR).
• Office Suite Applications: Antivirus software is not typically part of an office suite.
• File Format: Adobe Acrobat files are in PDF format.
• Booting: The process of loading the operating system is called booting.
• Operating System Examples: MS Access is not an operating system.
• Cache Memory: L1 cache memory is integrated into the CPU.
• Register Length: The length of a register is its word size.
• Web Browser Feature: A web browser seeks a website's address (URL).
• Top-Level Domains: .com is the most commonly used top-level domain.
• Collaborative Software: Groupware is another name for collaborative software.
• Screen Navigation: Scrolling moves page content up or down on the screen.
• Motherboard: The main circuit board in a computer is the motherboard.
• IP Address Assignment: DHCP protocols assign IP addresses to connected devices on the internet.
• Internet Protocol: TCP/IP is the fundamental internet communication protocol.
• Spreadsheet Software: Spreadsheet software is best for personal finance record-keeping.
• Signal Conversion: Computer signals for phone lines must be converted to analog signals.
• Network Layout: Network topology describes the physical layout of a network.
