4. Network
A computer network is a
set of computers
connected together for the
purpose of sharing
resources. The most
common resource shared
today is connection to the
Internet. Other shared
resources can include a
printer or a file server.
5. Topologies
In communication networks, a topology is a
usually schematic description of the
arrangement of a network, including its
nodes and connecting lines. There are two
ways of defining network geometry: the
physical topology and the logical (or
signal)topology.
7. Bus Topology
A bus network is a network topology in which nodes
are directly connected to a common linear (or
branched) half-duplex link called a bus.
8. Star Topology
A star topology is a topology for a Local Area
Network (LAN) in which all nodes are individually
connected to a central connection point, like a
hub or a switch.
9. Ring Topology
A ring network is a network topology in which each
node connects to exactly two other nodes, forming a
single continuous pathway for signals through each
node.
10. Mesh Topology
A network setup where each computer and network
device is interconnected with one another, allowing
for most transmissions to be distributed, even if one
of the connections go down.
11. Tree Topology
A tree topology combines
characteristics of linear bus and
star topologies. It consists of
groups of star-configured
workstations connected to a
linear bus backbone cable.
Tree topologies allow for the
expansion of an existing network
12. Cross Cable
An Ethernet Crossover Cable is a type of
Ethernet Cable which is use to connect
two computing devices together directly.
It is most often used to connect two
devices of same type: e.g. two
computers (via Network Interface
Controller) or two switches to each other.
