The Liquid Crystal Display or LCD

most common

How well did you know this?

Perfectly

The number of pixels on a display

Resolution

Perfectly

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

Dot Triad

How well did you know this?

Not at all

Perfectly

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

Dot Pitch

How well did you know this?

Not at all

Perfectly

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

Dot Pitch

How well did you know this?

Not at all

Perfectly

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

Refresh Rate

How well did you know this?

Not at all

Perfectly

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

Aspect Ratio

How well did you know this?

Not at all

Perfectly

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

Viewable Area

Perfectly

Consist of a cathode and anode within a vacuum tube

Cathode Ray Tube

How well did you know this?

Not at all

Perfectly

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

Cathode Ray Tube

How well did you know this?

Not at all

Perfectly

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

Liquid Crystal Display

How well did you know this?

Not at all

Perfectly

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

Liquid Crystal Display

Perfectly

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

Topology

How well did you know this?

Perfectly

What are the four common topology configuration

bus, ring, star, mesh

How well did you know this?

Not at all

Perfectly

Is a network in which all devices are physically attached on a single wire

Bus Topology

This type of topology does not need any switches or hubs

Bus Topology

A network in which the devices are connected in a circle

Ring Topology

Each device passes its received messages to the next node on the ring always in the same direction

Ring Toplogy

Network that has the devices connected to a central hub or switch

Star Topology

Can be thought of as a bus topology

Star Topology

Is the most commonly used network topology

Star Topology

The data are sent through the hub out to the destination device

Star Topology

Is used most often to connect networks to other netwroks

Mesh Topology

This type of network has redundancy built in with the multiple connections.

Mesh Topology

network that has multiple pathways interconnecting devices and networks

Mesh Topology

Is sometimes created so that larger networks an be segmented or broken up into smaller network

network bridge or network component

Is sometimes created so that larger networks an be segmented or broken up into smaller network

network bridge or network component

This reduces the network traffic, speeds up he overall network connection

Network component - Network Switch

Is similar to a hub but it sends data only

Network Switch

It will read the destination address from the data and select a direct path to ithe intended target

Network Component - Network Switch

When the hub receives data from a device, it generally sends those data to all devices connected to it

Network Hub

Are commonly used in small office and home application

Network Hub

Is the simplest device that can be used to connect several pieces

Network Hub

It has several wiring ports available on it to receive and transmit data

Network Hub

Provides the interface between the computer and network medium

Network Interface Card

Becoming more commonplace as technology

Wireless Connections

Uses glass threads to transmit data on the network

Fiber Optic Cable

Is surrounded by plastic protective covering

Fiber Optic Cable

Is much faster than its metal counterparts

Fiber Optic Cable

It is most often used in the infrastructure of the network

Fiber Optic Cable

Similar telephone wire , consist of four twisted pairs of copper wires

Twisted-Pair wire

It is the most commonly jsed connection medium in LANS

Twisted - Pairs wire

Similar to the wiring used for the cable television run into house

Coaxial cable

computer that can work independently

Thick client

Generally a high-end computer

Thick client

Generally a high end computer

Thick client

a device that is found on a network that requires services and resources from a server

Thin client

a computer that manages resources for other computers

Server

House application provide storage for files

Server

similar to a server based network computer that controls the operation of the network

Client-Based network

similar to a server based network

Client-Based network

There can be multiple servers on this type of network

Server-Based Network

Allows the users to move from computer to computer

Server-Based Network

The most popular small office or home network

Peer-to-peer Network

Each computer on the network is considered equal

Peer-to-Peer Network

Wide of these long distance communication links drive up

Wide Area Network (WAN)

A network that span a large area city, state, nation,

Wide Area Network (WAN)

Has the fastest communication technology

Local Area Network

The computer are interconnected and communicate by sharing images and reports

Local Area Network (LAN)

wireless access points

Local Area Network (LAN)

two or more objects sharing resources and information

Network

These device can be shared among a group of computers to save money and space for the users

Network

A diode is an electronic device that allows current flow in one direction

LCD-LED

Emits light when electrically stimulated

LED

The first LED semiconductor material was

Gallium Arsenide (GaAs)
