    Of course, computer networks can also be classified according to the 
    interconnection of devices: 
    • Computer networks organized by wireless technologies; 
    • Computer networks organized on the basis of cable technologies. 
    A local computer network is a type of computer network that is organized 
    in relatively small areas, in construction areas. For example, home, office, office 
    and institutional networks. 
    Local computer networks provide: 
    • Data sharing (Data Sharing). In LKT networks, data is stored on one 
    central computer, and data can be accessed by all workstations in the network. 
    This is the necessary information for everyone, and the need to store it on all 
    computers disappears. 
    • Sharing of information and technical resources (Resource Sharing): 
    • External memory devices (not including CD-ROM, DVD, ZIP, etc.); 
    External devices: printer, modem, etc. 
    • Software Sharing. All computers on the network can access the software 
    on the dedicated PC on the network. This eliminates the need to install the 
    program on all computers. 
    • Enables network data exchange and e-mail service. 
    A number of devices are used to build local computer networks and to 
    ensure that this network works in cooperation with another network. 
    The logical and physical interconnection of computers, cables and other 
    network components in a network determines the topology of this network.

    Network topology defines the connectivity of the network and not the scale of 
    the network. It is possible to distinguish several topologies used in the 
    construction of local computer networks. In general, topologies are divided into 
    physical and logical types. 
    Physical topology is the geometry of interconnection of devices in the 
    network, i.e. the property of connection from a physical point of view. Logical 
    topology determines the nature of data exchange in the network, or in other 
    words, determines the direction of data flow in the network. Local computer 
    networks have the following physical topologies:
