Basic Computer Principle

The sequence of instructions developed by a software programmer

Are programs that manage the resources of the computer system and simplify applications programming

They include such as the operating system, database management system, networking software, translator, and software utilities

Is the software that controls the computer hardware and acts as a bridge between application and the hardware

What are the three major OSs is use today

Is that series of instructions that organizes the course of data through the computer to the solution of a particular problem

Computer programs that are written by a computer manufacturer , by a software manufacturer, or by the users themselves o guide the computer to perform specific task

Allows programs allow users to print mailing lists, complete income tax forms, evaluate financial statements, or reconstruct images from xray transmission patterns

What are the two types of monitors

The cathode ray tube or CRT is

The Liquid Crystal Display or LCD

The number of pixels on a display

Grouping of one red dot, one green dot, and one blue dot

Measurement of how close the dots are located to one another within a pixel

May be expressed as aperture grille pitch, pixel pitch, or slot pitch, depending on the monitor maker

Measure of how fast the monitor rewrites the screen or the number of times that the image is redrawn on the display each sound

Ratio of the width of the monitor to the height of the monitor

Measured diagonally from one corner of the display to the opposite corner

Consist of a cathode and anode within a vacuum tube

Boils off a cloud of electrons and then a potential difference is placed on the tube

Produces images by shining or reflecting light through a layer of liquid crystal and a series of color filters

Has two pieces of polarized glass with a nematic liquid crystal material sandwiched between the two

Is the physical (geometric) layout of the connected devices on a network.

What are the four common topology configuration
