Study Notes

Cable routes are planned in accordance with network design and installation site.
Network materials are identified and obtained in accordance with established procedures.
Network topology refers to the layout of connected devices in a network.
Types of topologies include linear bus, star, tree, ring, mesh, and hybrid.
Advantages of linear bus topology include easy connection and less cable length, but disadvantages include network shutdown if the main cable breaks.
Advantages of star topology include easy installation and fault detection, but disadvantages include higher cost and disabled nodes if the hub fails.
Tree topology combines characteristics of linear bus and star topologies and allows for network expansion.
Ring topology forms a circular pathway for signals through the network and is good for handling high-volume traffic, but if one computer fails, the entire network goes down.
Mesh topology has direct point-to-point connections between every node and is robust, but requires a lot of cables and is expensive.
Networks can also be categorized according to role (peer to peer, client/server) and size/geographical location (LAN, MAN, WAN).

Intranet is a private network used by organizations with internet technologies.
Extranet is a private network for communication between clients, vendors, suppliers, etc.
Extranets allow for private communication, collaboration, knowledge sharing, document sharing, and data transfer between organizations.
Extranet is an intranet accessible to some people from outside the company or shared by more than one organization.
Intranet is insulated from the global internet.
Extranet serves an important role in allowing private communication and collaboration.
WAN is a wide area network that connects devices over a large geographical area.
WAN is used for communication between different intranets and extranets.
WAN uses different technologies like leased lines, satellites, and microwave connections.
WAN is used for the transfer of data and information between different networks.
