Study Notes

Computer Hardware and Software

Computer Peripheral Devices: The CPU is not a peripheral device. Peripherals are external devices like printers, keyboards, and mice.
Data Transfer: A port allows data transfer between computer devices.
Read-Only Memory (ROM): User-written data cannot be stored in ROM. It contains permanent instructions the computer needs to start up.
Byte: Eight bits equal one byte.
Megabyte: A megabyte is 1,000,000 bytes.
Device Drivers: Device drivers allow devices to communicate with a computer system.
Memory Types: Primary and secondary memory are two fundamental memory types.
CD-ROM: A CD-ROM is a non-erasable disk for digital audio.
Outputting: Outputting involves producing useful information for the user.
Plotters: Plotters create images and drawings.
CRT Monitors: CRT monitors are commonly used in non-portable systems, resembling televisions.
Drum Printers: Line printers that print one line at a time are called drum printers.
Output Unit Functions (Exception): The output unit presents processed data. It does not receive input data and instructions.
Bit: The smallest unit of data is a bit.
Input Unit Functions (Exception): The input unit receives data; it does not format it for users.
Data and Information: Data is the raw input, while information is the processed output.
Computer Characteristics (Exception): A computer's characteristics are not related to intelligence quotients (IQ).
Address Bus and Memory: The size of primary memory essentially depends on the address bus's size.
MAR: MAR stands for Memory Address Register.
Optical Disks: Optical disks utilize laser beams for data storage.
Address Bus and Secondary Memory: Secondary memory is independent of the address bus.
Optical Disk Types (Exception): Winchester is not an optical disk type.
Input Devices: Bar code readers are input devices.
Alternative Memory Names: Primary storage is another name for memory.
End-Users: Non-professional computer users are end-users.
Most Powerful Computers: Supercomputers are the most powerful computers.
Primary Storage Equivalents: Primary storage is also called memory.
Memory Types (Exception): QRAM is not a type of memory.
Microprocessor Alternative Names: A logic chip is also called a microprocessor.
Data Representation: Computers use a binary system (0s and 1s) to represent data.
Processor Speed: Personal computer processor speeds are measured in gigahertz.
Soft Copy: Soft copy refers to screen output.
Nonimpact Printers: Inkjet printers are nonimpact printers.
OMR: OMR stands for Optical Mark Recognition, also known as mark sensing.
Office Suite Components (Exception): Antivirus programs are not typically in office suites.
Adobe Acrobat Format: Adobe Acrobat files are in PDF format.
Booting: Booting involves loading the operating system.
Operating System Example (Exception): MS Access is not an operating system.
Cache Memory Location: L1 cache memory resides within the CPU chip.
Register Length: A register's length is its word size.
Web Browser Function: Web browsers find Uniform Resource Locators (URLs).
Most Used Top-Level Domain: .com is the most used top-level domain.
Collaborative Software: Collaborative software is also called groupware.
Scrolling: Scrolling moves pages up and down on a screen.
Motherboard: The motherboard is the main circuit board in a personal computer.
IP Address Assignment: DHCP assigns IP addresses to clients on the internet.
TCP/IP: TCP/IP is the protocol that controls Internet communication.
Spreadsheet Software Use: Spreadsheet software is suitable for personal finance records.
Signal Conversion for Phone Lines: Computer signals need analog conversion for phone lines.
Network Layout: Network topology describes the physical layout of a network.

Computer Hardware and Software (True/False)

CPU: The processor is also known as the central processing unit (CPU). (True)
