| LAN (Local Area Network) | a computer network contained in a clearly defined geographical area, such as in a single building or single campus |
| WAN (Wide Area Network) | a computer netwrok that spans large geographical areas like ocuntries and continents |
| MAN (Metropolitan Area Network) | a computer network confined to a single municipality that uses high-speed media like fiber-optics or dedicated digital lines |
| Peer-to-Peer Network | a network where all computers connected to the network can act as a provider or consumer of network resources |
| Client-Server Network | a network where one or more computers act primarily as providers of network resources, and one or more computers act primarily as consumers of network resources |
| Star Topology | a LAN physical topology where all nodes individually connect to a central computer or other device |
| Bus Topology | a physical topology where a single main cable called the bus or backbone carries all network data |
| Ring Topology | a physical topology where all nodes are connected in a continuous loop, and nodes relay information around the loop in a round-robin manner |
| Mesh Topology | a physical topology where each node has a direct connection to all other nodes on the network, providing dedicated, permanent point-to-point communication paths |
| Hybrid Topology | a physical topology where two or more basic topologies, such as bus, ring, star, and mesh, are combined |
| OSI (Open System Interconnection) Model | a model that describes network communication as consisting of seven layers that work to provide network services |
| 10Base5 (Thickwire or Thicknet) | Ethernet standard that uses coxial cable and supports transfer speeds to 10Mbps |
| 10Base2 (Thinnet)(Uses BNC Connectors) | Ehternet standard that uses 50 ohm coxial cable (RG-58 A/U) Transfers 10Mbps |
| 10BaseT (Uses RJ-45 Connectors) | Ethernet standard that uses twisted-pair cable. 10Mbps |
| CSMA/CD (Carrier Sense Multiple Access with Collision Detection) | system that enables dealing with packet collisions in an Ethernet network |
| Internet | the global network of computers constantly connected to each other using standardized communications protocols, specifically TCP/IP |
| Intranet | local network of computers using TCP/IP as standard communications protocol |
| Packet | collection of information, often used to refer to the chunks of information sent over computer networks |
| ISP (Internet Service Provider) | provides access to people or corporations to the internet |
| ISDN (Integrated Service Digital Network) | a digital line that's often used to connect ot the internet |
| IP Address | the specific network address of a computer on a network using TCP/IP as its network protocol |
| PPP (Point-to-Point Protocol) | the mode of transport used to connect a computer to the internet via a dial-up adapter |
| Extranet | like an intranet except that others outside of the network can access it |
| SMTP (Simple Message Transfer Protocol) | The standard e-mail protocol on the Internet. It is a TCP/IP protocol that defines the message format and the message transfer agent (MTA), which stores and forwards the mail |
| HTTP | The communications protocol used to connect to servers on the World Wide Web |
| HTML | The document format used on the World Wide Web |
| Protocol | rules governing the transmitting and receiving of data |
| Router | A device that forwards data packets from one (LAN) or (WAN) to another |
| Proxy Server | it is an application that breaks the connection between sender and receiver |
| PING Command (Packet Internet Groper) | used to determine if an IP is online |
