- 1NetworkA way or method of connecting different computers together.
- 2LANLocal Area Network.
A LAN is within the same building. - 3WANWide Area Network.
A WAN connects different buildings to each other. - 4WLANWireless Local Area Network.
It has the same features of a LAN, but no wires are connected. - 5Peer to Peer NetworkConnecting two computers together to communicate with each other.
A wireless internet connection is an example of a peer to peer network. - 6Client-Server NetworkConnecting a lot of computers together to communicate with each other.
The data is stored centrally unlike peer-to-peer networks. - 7TopologyThe different ways of how a computer can be joined together.
The three main ways of joining computers are bus networks, ring networks, and star networks. - 8Bus Network• has a central cable that all devices connect to
• only one device can access the bus at a time
• terminators are at the end of the bus network
• if it wishes to communicate, it checks if there is any traffic. If there is, it waits for random increments of time before trying again.
• peer-to-peer network - 9Ring Network• peer-to-peer network
• no central host computer and no nodes have overall control of access to the network
• an imaginary token is passed through a ring (token - a small packet that contains data)
• always the same route again and again
• only one device can use it at a time
• token attaches data to computer
• transmits messages in a circle - 10Star Network• client-server network
• most common type (used by schools and businesses)
• each node is connected to the central computer
• a home network is a star, connecting through the Wi-Fi router - 11IP AddressInternet Protocol.
Made of 4 bytes.
Used by computers to communicate with each other the same way people use phone numbers. - 12ProtocolA set of rules that all the devices on a network must follow to be able to communicate with each other.
- 13MAC AddressMedia Access Control.
Each device usually had this address hardwired into them when they are manufactured. - 14SMTPSimple Mail Transfer Protocol.
Used by computers to send e-mails. - 15HTTPHypertext Transfer Protocol.
Used by computers to display a web page. - 16PacketWhat the data is separated into.
- 17Domain NameThe name given to a web address to ensure that it identifies as belonging to a particular domain.
- 18Domain Name ServiceThe special servers that store the addresses on a web page.
- 19WWWWorld Wide Web.
The service that allows access of data from server to computer. - 20InternetA massive network of networks. People get access through the internet through Internet Service Providers (ISPs).
- 21Back-upA way of managing a network to ensure that the data doesn't get lost.
- 22MeshA network topology in which each node relays data for the network.
- 23SwitchA computer networking device that connects devices together on a computer network.
