A star is a basic topology of a computer network in
which all computers in the network are connected to a Central node (usually a switch), forming a physical network segment

Such a network segment can function both separately and as part
of a complex network topology (usually a "tree"). All information exchange goes only through the Central computer on which in this way very big loading therefore anything other, except a network is assigned, it can't be engaged. As a rule, it is the Central computer is the most powerful, and it is entrusted with all the functions of network management.

![Dignities failure of one workstation does not affect the operation](/_ipx/f_webp&q_80&fit_contain&s_1440x1080/imagesDir/jpg/364368/slide-3.jpg)
Dignities
failure of one workstation does not affect the operation of the
entire network;
easy search of faults and breaks in the network;
high network performance (subject to proper design);
flexible administration capabilities.

![Disadvantages failure of the Central hub will result in network](/_ipx/f_webp&q_80&fit_contain&s_1440x1080/imagesDir/jpg/364368/slide-4.jpg)
Disadvantages
failure of the Central hub will result in network (or network
segment) failure as a whole;
network laying often requires more cable than most other topologies;
the final number of workstations in a network (or network segment) is limited by the number of ports in the Central hub.

Application
One of the most common topologies, because it is easy to
maintain. Mainly used in networks where a category 3 or 5 UTP twisted pair cable is used.
