Computer networking refers to the communication of devices within a computer network. These devices communicate with each other by sending data through a shared medium, such as Ethernet cables, optical fiber cables, or wireless radio links.
A computer network may be as small as two devices or as large as millions of connected devices spanning the world. Computer networks are usually managed by professionals in order to ensure the security and stability of the data being transferred between devices.
Computer networking, also known as computer networking or data communication, refers to the technology involved in linking two or more computers together to exchange information and share resources such as files and peripherals.
A network can be either a small network of just two devices, such as an office printer and laptop computer, or it can be a complex network with thousands of devices spread out over miles of territory. The equipment that connects these different devices is called networking equipment, and it comes in many varieties depending on the type of network being built and the scale of that network.
Computer Networking
Computer networks are the connections between computers, devices, or other systems that allow them to share information with each other. Networks can either be local area networks (LANs) or wide area networks (WANs).
LANs connect devices located in the same general physical location, such as a home office or classroom. A WAN connects two or more LANs over a long distance using telephone lines, radio waves, satellite connections, fiber optic cables, or microwave towers.
Types of computer networks
Computer networks can be broadly classified into two categories, based on the type of connection between two nodes. Local area network (LAN) and wide area network (WAN). LANs connect computers to one another in a limited geographical area, usually a single room or building. WANs connect individual computers over large distances, usually in different cities or countries.
A LAN connects workstations with one another using local-area media such as Ethernet cables, or wireless links. The most common way to create a LAN is by using an Ethernet switch, which contains multiple ports that can be connected by either copper cable or fiber optic cable.
This connection between nodes allows them to share storage devices as well as data in order to communicate with each other. These connections allow for quick access to shared resources without waiting for long transfers across wide area networks. Some examples of LANs include Intranet, WAN, Internet, and Bus systems.
A WAN consists of two or more interconnected lines leased from a phone company that operate at the same speed and provide data transmission speeds up to typically 1 Gbit/second. Some examples include: Frame relay and Packet switching are popular methods of communication. Frame relay transmits data in blocks called frames.
Packet switching is a more efficient method of sending information because it divides the message into packets that transmit individually over various routes through the internet. When they reach their destination, they are reassembled according to their original message sequence and delivered to their intended recipient. With packet switching, there is no limit on how many messages can be sent simultaneously because it does not rely on special channels like frame relay does.
Small business computer network example
A small business network example would be a company with three employees. The first employee has an office on the first floor, the second employee has an office on the second floor, and the third employee works from home.
This company would need to have a router installed to allow for internet access, as well as for file sharing between all of the computers. Also, there would need to be network security in place in order to protect data from outside intruders. It’s important that these networks are updated frequently so that they can keep up with new technology developments and increase efficiency.

Home computer network examples
A home network is a set of devices that share resources like a printer, files, or the internet. The easiest way to connect your devices together is by using an ethernet cable. You can also use Wi-Fi to connect your devices wirelessly.
Two basic types of networks: wired and wireless. Wired networks involve connecting devices with ethernet cables. Wireless networks involve connecting devices wirelessly with Wi-Fi. If you have many computers in your house, then it’s best to have a wired home network setup so you don’t run out of bandwidth and compromise the connection speed for all the computers on your network.
If you have only one or two computers in your home and they’re both close to each other, then it doesn’t really matter which type of network you use because their connection speeds will be fast enough.
Types of devices used in computer networking
Computer networks consist of computers that are connected together, and can be accessed remotely. The four major types of computer networks include: * Local area network (LAN) – A LAN consists of a few computers in close proximity to one another.
This type of network is most often used in homes, small businesses, schools, or other small organizations. * Wide area network (WAN) – A WAN consists of two or more LANs that have been interconnected.
Some common examples include the Internet or a company’s intranet. * Personal area network (PAN) – A PAN includes wireless devices such as Bluetooth-enabled devices, smartphones, laptop computers with built-in wireless cards, etc., which create a private wireless connection between themselves within a range of 10 meters or less. It is typically used for personal items like MP3 players, mobile phones, and tablet PCs.
* Metropolitan area network (MAN) – A MAN consists of two or more local area networks that share a common backbone; it is typically found in large buildings like colleges, office buildings, airports, stadiums and convention centers.
Examples of device-level network configuration issues
Device level network configuration issues often arise due to poor installation. This can include an incorrectly configured IP address, improper subnet mask, or DNS server settings. A improperly configured DHCP server can also lead to poor device-level network configuration. The symptoms of this problem may manifest themselves as a complete lack of connectivity or random connection drops. These problems typically happen because the devices on the network aren’t communicating with one another properly.
Summary
Computer networks allow computers to share resources. These can include hardware, software, data, a connection to the internet, files or any other resource that can be shared with other computers on a network. Computer networks come in two forms: wired and wireless. Wired networks use cables to connect devices while wireless networks use radio waves to connect devices wirelessly.
Wired connections tend to have more bandwidth for transferring information which makes them faster than wireless connections but they require the installation of wires which can be difficult depending on your home’s layout. Wireless connections usually have less bandwidth but require no installation.
Computer networking, or simply networking, refers to the interconnection of computing devices to share data and communicate with each other over a network. A computer network allows computers to exchange data via various methods and media, such as telephone lines and cables, radio channels and satellites, microwaves and even optic fibers, in order to communicate directly without any intermediaries.
