A
computer network is a group of autonomous computers interconnected
with the help of a
certain technology. Two computers are called related
if they are able to exchange information between them. Linking can be accomplished by means of electric cables,
optical fibers, microwaves,
infrared rays or
through satellites. Networks have different
shapes and sizes.
Typologies of connecting computer networks
Network topology is the pattern of connections which connect pairs of network nodes. Is a form of LAN network or any other communication system. A given node has one or more links to other, and these connections can occur in a variety of different forms. The simplest connection is one-sided relationship between two entities or funds. The second link can be added for two-way communication. The topology of the network is determined by the configuration of connections between nodes. Network topologies are divided into these basic categories:
Linare - (line)
Highways - (bus)
Star - (star)
Ring - (ring)
Wood - (tree)
Mesh
linear topology
Linear topology creates a mutual connection between a computer and the computer next. This experience is the beginning of computers, since each computer, except at the beginning and end, requires two receiver and two transmitters.

bus topology
bus topology characterized by column presents the main transmission grid where computers are connected. This topology is estimated liabilities for computers connected to the highway just "watching" what happens in it. When the notice through the network card that the data are then directed to the data they receive. When the computer is prepared to give information, he at first determined that no other computer does not send data highway, and then sends its information packages. The highway network as coaxial cable used more often. (this cable is very little different from ordinary cable TV's). networks with topology associated highways and extend light compared with other typologies they require a certain amount of cabling. In networks with frequent topology highways are where cable outages can hardly be detected. If a connector is removed around the nets fall. These nets are rarely used today left over from the past. In the picture looks topology highways.

star topology
In star topology computers are connected to central connection device which is called the hub. Each computer is connected to a separate cable to the hub. Because each computer connected there is a special cable and special port for connection, the Nets could easily be expanded. Limitation may be only the number of entries in the hub. If a computer goes out other computers can work without problem between them. Most sensitive is the central distributor. In star topology distributor serves as the central connection point as seen in the picture.

Tree topology (tree form)
Tree topology (tree form) can be viewed as a collection of star networks located in the hierarchy. This arrangement of a tree has individual peripheral nodes that have the duty to receive and transmit only from the joints and not be required as a repeater or regjeneratorë. In contrast to the central node star topology can be distributed.
As in conventional star network, individual nodes can be isolated from the network with a single defect of a single point of transmission. If a network connection with the leaf of a tree fails, he stalks (leaf) isolated: if a connection to the node which is not a leaf falls, a whole sector of the network isolated from the rest.
To alleviate the amount of data traffic coming from the transmission of any information and any country, have created the most advanced nodes to be accountable for the identity of the different systems connected to the network. These Switch-a network will learn the basis of the network and transmit the data packets everywhere and then observing responses come from the pack.

hybrid topology
Hybrid networks use a combination of two or more topologies in such a way that results in the network do not have any of the standard.
The two most common examples of hybrid networks are:
Star-ring network (star ring) consists of the eye or star topology mëshomë associated with (MAU) acces multistation unit as central HUB
Network-highway star (star-bus) consists of two or more related with star topology (bus trunk).
