Define Alpha

In-house group of programmers

Capture data with sensors (temperature, sound, pressure, light, chemical, etc.).

Data represented in discrete quantities

Define Beta

Who, What, validation, processing - Interview, surveys, existing documents, search

Ability to randomly access an arbitrary element in equal time. Used in stores

Selected group of outside users that are willing to give feedback on program.

Define Data Collection

Converts HLL to machine code and creates variable memory location

Who, What, validation, processing - Interview, surveys, existing documents, search

Periodic reviews, corrections, debugging, improvements, re-testing and evaluation.

Define Defragmentation

Group related disk areas to improve the speed at which data can be accessed.

Exchange of signals between devices that protocol has been followed.

Recording of a series of keystrokes.

Define Digital

Data represented in discrete quantities

Adv. = when old and new are totally different. Dis = possible loss of data, crashes

Soft/hardware protection between network and outside world - inspects data

Define Direct Access

Adv. = when old and new are totally different. Dis = possible loss of data, crashes

Ability to randomly access an arbitrary element in equal time. Used in stores

Group related disk areas to improve the speed at which data can be accessed.

Define Direct Change

Network with unlimited connections world wide

Purpose, meaningful identifiers, indentation, diagrams, User instruction (low-tech).

Adv. = when old and new are totally different. Dis = possible loss of data, crashes

Define WAN

Network with unlimited connections world wide

Software/hardware that allows connection to other networks

Soft/hardware protection between network and outside world - inspects data

Define Documentation

Estimate cost, expected benefits, time to develop and implement, difficulties, risks.

Purpose, meaningful identifiers, indentation, diagrams, User instruction (low-tech).

Soft/hardware protection between network and outside world - inspects data

Define Feasibility

Purpose, meaningful identifiers, indentation, diagrams, User instruction (low-tech).

Device that connects network components without regard to destination of data.

Estimate cost, expected benefits, time to develop and implement, difficulties, risks.

Define Firewall

Adv. = small sections tested and confirmed to work. Dis= extended training time

Soft/hardware protection between network and outside world - inspects data

Lower and upper limits of data

Define Gateway

Returns the remainder after integer division.

Software/hardware that allows connection to other networks

Temp = A; A = B; B = temp;

Define Handshaking

Returns the remainder after integer division.

Exchange of signals between devices that protocol has been followed.

Used to store programs and variables while in execution. Cache RAM and ROM

Lexical

Removes all spaces and comments then looks for key words

Periodic reviews, corrections, debugging, improvements, re-testing and evaluation.

Adv. = small sections tested and confirmed to work. Dis= extended training time

Define Macro

Agreed upon formats and procedures related to data transfer

Capture data with mouse, keyboard, joystick, or touch screen.

Recording of a series of keystrokes.

Define Modulus

Security digit added to ensure that the number of bits is always even or odd

Lights, printer, LCD, actuators, switches, converters, plotter.

Returns the remainder after integer division.

Define Operating system

Program designed

Returns the remainder after integer division.

Adv. = Check new and old together, no loss of data, Dis= twice the work

Define Parallel Change

Interference which can alter data during transmission

Adv. = Check new and old together, no loss of data, Dis= twice the work

Analysis > Design > Construction > Test - Install > Maintenance > Analysis

Define Trace

Following the steps of an algorithm to completion or error.

Hardware/software, functions personal and tasks, formal performance agreement

Sequential data access in order used in payroll accounts

Define Virtual

The meaning of the procedure not detected by the compiler.

An extension of primary memory created by using a secondary swap file

Adv. = small sections tested and confirmed to work. Dis= extended training time
