Study Notes

Computer Components and Peripherals

Peripheral devices are not considered part of the computer itself. Examples include mouse, monitor, keyboard, CPU.
A drive is a place in the system unit that allows data transfer between different devices/computers.
RAM is a computer memory where users cannot write new instructions or information.
A group of 8 bits is a byte.
A megabyte equals 1,000,000 or 2²⁰ bytes.
Device Drivers are used by input/output devices to communicate with the rest of the computer system.
Translators change a language to another language.
Utilities help in maintenance.
Operating Systems control the resources of a computer, including memory, software, and hardware.
These are types of memory Primary and Secondary.
A CD or DVD-R/RW are examples of an erasable disk that stores digitized audio information
Controlling, outputting, inputting and processing are all part of data/information processing
Monitors, printers, and plotters are used to give single or multiple colored images/drawings.
Line Printers print one line at a time; Laser Printers, Inkjet Printers, and Drum/Chain Printers are different types of printers. Examples of displays include CRT, LCD,and LED.
The smallest data unit in a computer is a bit.

Computer Functions and Data

Input data, instructions, and information, output processed data. Data is converted into computer-readable format and output as desired.
An important characteristic of a computer is its ability to hold data and retrieve it later when needed.
Most computers use a binary coding to represent data, with each bit representing an on/off state (0 or 1).
CPU's main work is processing.
Examples of computer classifications include microcomputers, mainframes, and supercomputers.
Input and Output units are controlled by a computer's arithmetic and logic unit (ALU).
Secondary memory is non-volatile, meaning it remembers data when the computer is turned off, which is a huge difference from the primary memory.

Computer Memory and Storage

MAR stands for Memory Address Register.
Memory, Registers, Cache, are types of memory that are used to store data.
True or False statements can be evaluated to understand data relationships and processes.
Optical disks are a good example of secondary storage, which is used to store data long-term.
The speed of optical disks is dependent on how quickly the disk can rotate the disk and how quickly data can travel to the correct sector.
Different technologies like Reflective, Refractive are used for storage capacity of optical disks; capacity is calculated using units.
Dot pitch, refresh rate, and Pixel speed, are used for specifications in regards to visual displays.
Other memory types include RAM, ROM, CMOS, and RWM.
Cache, Primary, and Secondary are types of memory storage.

Computer Hardware and Software

Monitors, Printers, Plotters are some examples of peripherals.
There are different types of optical drives such as DVD and CD.
Input, Output, and Storage are some major components.
Output devices deliver data to the outside world.
Software is a set of instructions making up the computer program (ex: freeware, shareware, database, etc.).
Different types of software include operating systems, and other programs to complete tasks.
Operating system (OS) manage computer hardware.

Computer Operating Systems and Networks

Boot is a term used in computer science when the operating system (OS) is loaded into the computer's memory.
Booting means to start up a personal computer or other electronic devices.
GUIs, command line interfaces, multitasking, single-tasking, graphical user interfaces, and operating systems are examples of different software.
Computer Networks interconnect computers for data exchange in a variety of ways (e.g., WAN, LAN, MAN).
Internet is a global network of computers.
Protocols are sets of rules to transmit data over networks. Different protocols are used for different tasks.
Examples of protocols include HTTP, FTP, TCP/IP, DHCP, etc.
A computer's MAC (Media Access Control) address is a unique identifier assigned to network interface cards (NICs) that uniquely identify them.

Computer Programming

Programming languages help programmers convert instructions into a language a computer understands.
Programming languages convert instructions into a language a computer understands, so the computer can execute (carry out) the instructions.
Pseudocode is a language similar to english, outlining the instructions without syntax of programming language (used to describe programming algorithms).
