Topology (network)
Node
A basic unit of a data structure, such as a linked list or tree data structure.
Default gateway
A device, such as a DSL router or cable router, that connects the local network to the Internet.
IP address
The unique identifying number assigned to every device connected to the internet.
Subnet mask
A 32-bit address that segregates an IP address into network bits that identify the network and host bits that identify the host device operating on that network.
Topology (network)
Used to describe the physical and logical structure of a network.
Peer-to-Peer
Characteristics:
Each computer is linked to one or more computers directly rather than going Computer through a server. There are several forms of peer-to-peer networks.
Uses:
In a peer-to-peer (P2P) network, all computers have equal status - no computer has control over the network.
Star network
characteristics
All computers communicate through the central hub. All transmissions received from a peripheral on the star are broadcast to all peripherals by the central device. The benefit is that if one peripheral goes down the rest can continue to communicate; however, if the hub goes down the whole network is compromised. The cost of the cabling can also be expensive if the network is extensive.
Uses:
Star networks are commonly used to connect devices such as computers, printers, and other peripheral devices in home networks.
Bus network
Characteristics:
The nodes are connected to a bus (a central cable which transfers all data on the network).
Uses:
Small workgroup local area networks (LANs) whose computers are connected using a thinnest cable.
Ring network
Characteristics
A token (small data packet) is sent around the ring in one direction, being passed from one computer system to the next. A computer seizes the token and includes its own data when it transfers data.
Uses:
In colleges, campus computers are linked in nodes, and the data is sent from one device to another in the small machine network.
Mesh network
Characteristics:
In a mesh network, each computer system is connected to every other computer system.
Uses:
Data packets are transferred to the destination address along the quickest path, travelling from node to node. If a pathway is broken, there are many alternative paths that the packets can take.
