Topologies
A topology that uses less cable and has no alternate routes.
What is a point-to-point topology?
Messages distributed by electronic means from one computer user to one or more recipients via a network.
What is email?
Computer designed to process requests and deliver data to another computer over the internet or a local network. Stores all software and controls the network.
ALSO
Brings internet to devices. Needed in order to connect more than one device to the internet (directs data to specific device).
What is a server?
ALSO
What is a router?
Storing a website or other data on a server or other computer so that it can be accessed over the internet.
What is hosting?
A type of computer network that is used for larger geographical areas such as countries or continents.
What is a Wide Area Network (WAN)?
A topology that is expensive and when one device in the network breaks the entire network goes down.
What is a ring topology?
How nodes are connected.
What is communication media?
Connects devices. Is not intelligent and cannot identify which device the data packet is intended for, so it copies the data to each device in the network. Causes security risks and unnecessary traffic (wastes bandwidth). Used in LANs only.
What is a network hub?
A set of rules governing the exchange or transmission of data between devices.
What is protocol?
*File Transfer Protocol: communication method for sending data between computers on the internet.
A type of computer network that can span one building or several, like a group of university buildings.
ALSO
More specific type of LAN based on radio transmissions.
What is a Local Area Network (LAN)?
ALSO
What is Wireless Local Area network (WLAN)?
A cheap and simple topology that requires a terminator.
What is a bus topology?
What is a fax?
Translates from digital (signals computers understand) to analog (signals the internet sends) and vice versa. Allows connection to service provider to be maintained.
What is a "Modulator Demodulator" or modem?
*modems are built into most routers
Hardware device that is generally attached to a computer to allow it to connect to a wireless system.
What is a wireless adapter?
A computer network designed for geographical areas like cities or counties. Often used fibre optic cable.
What is Metropolitan Area Network (MAN)?
A fast-connecting topology that depends on a central device.
What is a star topology?
Messages exchanged in near-real time using a standalone application or embedded software.
What is IM?
Accepts ethernet packages. It is intelligent, because it learns the MAC addresses of packages and sends them to the correct device. Used within LANs.
What is a network switch?
Public place where internet access is possible.
What is an internet access point?
A part of a computer network which is designed to block unauthorized access while permitting outward communication.
ALSO
A network of PCs each of which acts as both client and server so that each can exchange files directly with every other computer in the network. No server.
What is a firewall?
ALSO
What is a peer-to-peer network?
An expensive topology that has multitudes of alternate routes and requires a lot of ports.
ALSO
The part of a device where ethernet cables can be put into ports to physically connect a network. Can have one or more ports.
What is a mesh topology?
ALSO
What is a Network Interface Card (NIC)?
What is Bluetooth?
Computer, phone, router, server or other device that acts as end-points for communication.
What is a node?
*routers/servers can redirect communication to other nodes.
A family of network protocols that allows devices to connect to the internet wirelessly (brand name for a type of wireless LAN)
What is Wi-Fi?
Measures how much data can be transferred at one time. Usually measured in bits (b) or bytes (B). Almost synonymous with Data Transfer Rate.
What is bandwidth?
