Computer Netwoking
Computer networking refers to interconnected computing devices that can exchange data and share resources with each other. These networked devices use a system of rules, called communications protocols, to transmit information over physical or wireless technologies.
Computer networks enable efficient resource sharing, provide a platform for remote database access, avenues for interactive communication, and improve data integrity, reliability, and security.
How does a computer network work?
Specialized devices such as switches, routers, and access points form the foundation of computer networks.
Switches connect and help to internally secure computers, printers, servers, and other devices to networks in homes or organizations. Access points are switches that connect devices to networks without the use of cables.
Routers connect networks to other networks and act as dispatchers. They analyze data to be sent across a network, choose the best routes for it, and send it on its way. Routers connect your home and business to the world and help protect information from outside security threats.

Types of Networks
Saepe quo labore aenean dictumst expedita commodi auctor, nisl, lorem iusto feugiat nemo reiciendis laboris.
1
Local Area Network (LAN)
A LAN is a collection of connected devices in one physical location, such as a home or an office. A LAN can be small or large, ranging from a home network with one user to a large enterprise network with thousands of users and devices. A LAN may include both wired and wireless devices.
Regardless of size, a LAN’s particular characteristic is that it connects devices that are in a single, limited area
2
Wide Area Network (WAN)
A WAN extends over a large geographical area and connects individual users or multiple LANs. The Internet can be considered a WAN. Large organizations use WANs to connect their various sites, remote employees, suppliers, and data centers so they can run applications and access necessary data.
Physical connectivity in WANs can be achieved by leased lines, cellular connections, satellite links, and other means.
3
Enterprise Network
A network built for a large organization, typically called an enterprise, needs to fulfill exacting requirements. Since networking is crucial for any modern enterprise to function, enterprise networks must be highly available, scalable, and robust. These networks have tools that enable network engineers and operators to design, deploy, debug, and remediate them.
An enterprise may use both LANs and WANs across its campus, branches, and data centers.
4
Service Provider Network
Service providers operate WANs to provide connectivity to individual users or organizations. They may offer simple connectivity, in the form of leased lines, or more-advanced, managed services to enterprises. Service providers also supply Internet and cellular connectivity to their customers.
