Networking and Internet
It is a computer network is a group of computers or servers that use a set of common communication protocols over digital interconnections for the function of sharing resources located on or provided by the network nodes. The interconnections between nodes are formed from a broad spectrum of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network analysis situs.
Computer networks for the home and small business can be built using wired or wireless technology. In the past, a wired Ethernet has been the option is used in homes, but Wi-Fi wireless technology has improved greatly and is now commonplace.
Wired and wireless networks have advantages and disadvantages. They equally epitomise practical choices for home or other local area networks (LANs) and depend on the packages purchased by the user.
When possible, I prefer wired solutions as performance and security are better and more reliable. Wireless networks are convenient but can have performance and security issues.
Both have advantages and disadvantages.
Wireless networks allow devices to stay connected to the network but roam untethered to any wires. Access points amplify Wi-Fi signals, so a device can be far from a router but still be connected to the network. When connected to a Wi-Fi hotspot at a public place, café, hotel, airport lounge, the connection is with that business's wireless network.
Wired networks use cables to connect devices, such as desktop computers, laptops, or servers to access the Internet or additional network. A wired network has disadvantages when compared to a wireless network, the largest is that the device is tethered to a router.
Motherboards have at least one RJ-45 networking socket and some have integrated Wi-Fi adapters fitted.
A computer network is a collection of computers and/or hardware interconnected by communication channels that allow sharing of resources and information.
It is where a device, computer or server sends or receives data to or from another device, computer, or server in a remote location. When connected, the two devices are said to be networked. A network is a group is the sum of computers, tablets, phones, laptops, and servers that are connected. Networks are organised in a diverse group of physiognomies, such as, the method used to carry the data and communications protocols.
Communication protocols define the rules and data formats for swapping information in a computer network and provide the basis for network programming.
Router
A router is a networking device that forwards data several layer packets between computer networks, such as files, communications, and transmissions. Routers perform the traffic directing functions on the Internet. Data sent through the internet, like web pages or emails, data packets, a packet is normally forwarded from one router to router through the networks that make up the Internet until it reaches its destination node.
Data packets have several layers, or sections, one of which carries identifying information such as sender, data type, size, and most importantly, the destination Internet protocol (IP) address. The router reads this layer, prioritizes the data, and chooses the best route to use for each transmission.
