Study Notes

Computer Processes and Hardware

Computers are directed by software, but performed by hardware
WAN (Wide Area Network) connects computers over large distances
CPUs (Central Processing Units) consist of control units and arithmetic/logic units
Serial processing involves handling instructions one at a time
Machine cycles have instruction time (I-time) during decoding
Compilers translate programmer instructions into computer language
Data represents facts, figures, or ideas (numbers, words, images, etc.)
Kernels are resident operating system programs in memory
Defragmenters reorganize disk files for better storage
MHz abbreviates Megahertz (a unit of frequency)
Web browsers allow internet exploration
Byte is a group of 8 bits
Apple MAC introduced the Graphical User Interface (GUI) in 1984
Machine cycles involve instruction time (I-time) and execution time (E-time)
Bits are binary digits (0 or 1)
Cache memory is temporary storage for data between memory and CPU
Dot matrix printers use a print head to imprint characters on paper

Computer Components and Usage

Motherboards are the main circuit boards in computer systems
Computers are used in many fields (medicine, industry, finance)
Multiprocessing uses multiple processors simultaneously
Modern machine cycles include fetch, decode, execute, and store steps
RAM (Random Access Memory) is user-writable memory
ROM (Read-Only Memory) is non-writeable memory
File compression utilities decrease storage space
Command-line interfaces use text commands
Shells provide a user-friendly environment for interaction
File Explorer is a file management utility
Shareware is software that can be tried before purchase
Pipelining allows overlapping steps in machine cycles
System buses connect CPUs to memory
Dot pitch measures pixel spacing on screens
GUIs (Graphical User Interfaces) are user-friendly interfaces
.accdb is the extension for Microsoft Access files
Uninstalling programs is done via the Control Panel
Vertical or Enterprise applications are used in company divisions
TCP/IP stands for Transmission Control Protocol/Internet Protocol

Computer Signals and Networking

Analog signals are used in telephone systems
Computers can be used in finance, such as in banking and stock trading
Modems convert between digital and analog signals
Bluetooth utilizes short-range wireless connections
WAPs (Wireless Access Points) allow devices to connect to networks
ISPs (Internet Service Providers) connect users to the internet
NICs (Network Interface Cards) connect computers to networks
Output devices translate electronic data into other formats
