This document discusses network technologies and provides information on computer networks. It defines a computer network as a type of digital telecommunications network that enables the exchange of resources between various types of networks. The document outlines different types of networks including personal area networks (PAN), local area networks (LAN), and wide area networks (WAN). It provides details on each type of network and discusses the advantages and disadvantages of using networks.

What is a computer network? A type of digital telecommunications network that enables the exchange of resources between various types of networks. Using connections between nodes, computing devices communicate with one another in computer networks.
Types of networks. The followingare considered commonly used form of networks available: PAN LAN WAN Let us discuss each in detailin the following slides
PAN (Personal Area Network). A PAN is a network of information technology devices that are connected inside the physical space of a single user. The standard distance is ten meters. Among them could be laptops, telephones, printers, or smartphones.
LAN (Local Area Network). LANs are networks used when computers in an schools require to interact with one another. For a LAN connection, the following are required: Cables (wired and optical), file server terminals, and print servers. LAN does not span over a geographical area greater than a city.
WAN (Wide Area Network). WANs are used when computers from many locations or continents must connect. WANs span over a large geographical area. A common example of a WAN is the Internet. These networks are used by industry, government, and educational institutions to send data to workers, students, customers, and buyers as well.
Advantages of using networks. LAN Through computers linked together, we can send data and messages without difficulty. The fact that all data is saved on the file server, data backup is simple. WAN Spans a wider geographic region. Enables individuals or scattered workstations to share resources and programs.
Disadvantages of using networks. LAN Spans over small geographical area. Calls for ongoing LAN management due to problems with software configuration WAN It is not cheap to setup. Provides fewer safety precautions than various types of networks. Loss of autonomy.
The End.
