Network Topology - Linear Bus

The Linear Bus Topology basically is a wire, with all the computers connected to it (as shown in the diagram). Terminators are required because without terminators the BUS will suffer major signal reflection and distortion.
General Information
Developed in 1976
Later IEEE defined the Ethernet standard
The first versions ran at 3 Mbps
The current versions run at 10 Mbps [...]

Network Topology - Token Ring

This networking topology is very basic. It uses STP cabling and it is more reliable. This network topology does not have collisions like the linear bus topology, because all the nodes are connected in a loop, and a token is used to allow the nodes to send data. A node cannot send data unless it [...]

Network Topology - Star

The star network is a centralized network, because each node is connected to a centralized hub (switch). When a node sends data to another node, the data needs to go through the centralized hub. Usually this network uses UTP cable, but if higher speeds are needed, fiber optic can be used.
The advantages of this network [...]

Networking - General Information

In this post we will go through some general stuff regarding Networking. This is important, because it’s a common thing that in every household we have more than one computer, and most of the time we need them networked. In future posts we will go through different types of network setups.
Technical Words
Node: A terminal and/or [...]
