Computer Monitors

• CRT monitors are similar to televisions and are used with nonportable computers.
• LCD, flat panel, and LED monitors are lightweight and used in portable and non-portable computer systems.

Input Unit Function

• It reads instructions and data from outside the computer world.
• It does not convert the data into a usable format for human understanding.
• It does not include converting or formatting data for human understanding.

Data

• Data is the raw material used as input for processing. This creates information.

Computer Characteristics

• Speed, accuracy, and capacity are characteristics of computers, not IQ.

Memory

• Memory is an electronic holding place for data retrieval later.

Memory Size

• The size of main memory depends on the size of the address bus.

Memory Types (Independent of Address Bus)

• Secondary memory

MAR

• MAR stands for Memory Address Register.

Optical Disks

• Optical disks are a promising random access medium for high-capacity secondary storage.

Optical Disk Technology

• Optical disks use laser beam technology.

Optical Disk Storage Capacity

• The capacity of an optical disk is calculated by multiplying the number of sectors by the number of bytes per sector.

Disk Rotation

• Disk rotation must vary inversely with the radius of the disk.

Disk Sectors

• Disk sectors maintain a constant size.

Optical Disk Access Time

• The access time for optical disks typically ranges from 100 to 300 milliseconds.

Laser Beam Technology

• Laser beam technology is used in optical disks.

RAID

• RAID (Redundant array of independent disks) is a method to combine multiple disk packs for a storage unit function.

Updating In Place

• The process of updating a disk record to its original location.

Scrolling

• Moving a page up or down on a computer screen.

Harmful Programs

• A virus is a harmful program.

Recently Used Data/Programs

• Recently used data is swapped into memory.

Storage Unit

• The storage units hold data and instructions to be made readily available.

Vertical Market Software

• Software written specifically for a given business type.

Software Piracy

• Making illegal copies of copyrighted software.

Desktop Publishing Software

• Software used to create professional newsletters and reports.

Database Management Software

• Software used to store, update, manipulate, and retrieve data.

Commercial Software

• Packaged software

Office Suites

• Antivirus software is not typically included in office suites.

Emulation

• Software that makes a personal computer function like a terminal.

Browser

• Software on a user's computer that provides a graphical user interface for accessing the Internet.

Web Site

• A website is a location on the World Wide Web.

Protocol

• TCP/IP is the protocol used to facilitate communication on the internet

Thin Client

• This is a stripped-down computer that accesses network resources.

Earth Stations

• Devices used to communicate with satellites

Transponder

• Devices used in satellite transmission

Digital Medium

• A cellular phone is the least susceptible medium to noise.

Token Passing

• A method used by Token Ring networks to control network access.

Client/Server Relationship

• Processing done by a server and access by a client.

Distortion

• Distortion in a signal is called noise.

Data Representation

• Data is represented by the binary system (0s and 1s).

Computer Memory Unit

• The term "memory" is often used in place of primary storage, used for the rapid retrieval of data.

CPU Components

• A CPU has two parts: The Control Unit and the ALU (Arithmetic Logic Unit).

Machine Cycle

• A machine cycle is the time necessary to take the steps to fetch, decode, execute, and store an operation.

Computer Software

• Software is step-by-step instructions to run the computer.

Computer Types

• Microcomputers are desktops and personal computers.

Computer Data

• Information is processed data.

Computer Units

• Printers and screens are output units.

CPU Functions

• The CPU does calculations, moving and processing data. It executes instructions and interacts with memory and other computer components.

Computer Coding

• ASCII is the most widely used coding scheme.

Computer Memory

• RAM stores data to be accessed quickly for processing.

Computer Memory

• RAM is a volatile memory- loses data when power is off.

Computer Storage

• Secondary storage devices are long-term, and data remains stored when power is off.
• The secondary storage holds data that is not immediately needed for processing.

Computer Components

• CPU contains the Control Unit and the ALU, which perform the calculations.
