In the world of PCs, networking is the practice of linking at least two processing devices together to share data. Networks are worked with a combination of PC hardware and PC software. A few clarifications of networking found in books and tutorials  are profoundly technical, designed for students and professionals, while others are geared more to home and business employments of PC networks. Here's a quick, simplified look at the fundamental ideas of networking.

1. Types of Computer Networks


Networks can be classified in a few different ways. One method defines the kind of a Network according to the geographic area it spans. Alternatively, networks can likewise be classified based on topology or on the types of protocols they support.

2. Types of Network Equipment: The Hardware


The building blocks of a home PC network include adapters, switches, as well as access points. Wired (and hybrid wired/wireless) networking additionally includes cables of varying types. At last, large-scale enterprise networks, specifically, often employ other advanced equipment for specialized communication purposes.

3. Ethernet


Ethernet is a physical and data link layer innovation for local area networks. Homes, schools, and offices around the world all commonly utilize Ethernet-standard cables and adapters to network personal PCs.

4. Wireless Local Area Networking (WLAN)


Wi-Fi is the most prevalent wireless communication protocol for local area networks. Private home and business networks and public hotspots utilize Wi-Fi to connect PCs and different wireless devices to one another and the Internet. Bluetooth is another wireless protocol regularly used in cellular phones and PC peripherals for short-range network communication.

5. Internet Service


The technologies used to connect to the Internet are different than those utilized for connecting devices on local area network. Digital subscriber lines (DSL), cable modems, and fiber give settled broadband internet service, while WiMax and LTE also support mobile connectivity. In geographic areas where these high-speed alternatives are unavailable, subscribers are forced to utilize more established cellular services, satellite, or even dial-up internet .

6. TCP/IP and Other Internet Protocols


TCP/IP is the essential network protocol of the Internet. (The acronym refers to Transmission Control Protocol and the Internet Protocol, the two frameworks on which the model is based.) A related family of protocols built over TCP/IP permits web browsers, email, and many different applications to communicate across networks globally . Applications and PCs utilizing TCP/IP identify each other with assigned IP addresses, which are a series of numbers that typically looks like ###.##.###.

7. Network Routing, Switching, and Bridging


Most PC networks direct messages from source to destination devices utilizing any of three techniques: routing, switching,  and bridging. Routers utilize certain network address data contained inside messages to send them ahead to their destination (often via different routers). Switches utilize much of same technology from routers yet typically support local area networks as it were. Bridging permits messages to flow between two different types of physical networks.
