Understand the different types of switches available so you can make the right choices for your small business. Understanding the types of network switches will help you find the right solution to keep up with your changing business requirements. Think about the categories of switches as well as specific switch benefits as you explore your options.

Chapter 1: What is a Network?

Computer network , two or more computers that are connected with one another for the purpose of communicating data electronically. Besides physically connecting computer and communication devices, a network system serves the important function of establishing a cohesive architecture that allows a variety of equipment types to transfer information in a near-seamless fashion. LANs connect computers and peripheral devices in a limited physical area, such as a business office, laboratory, or college campus, by means of links wires, Ethernet cables, fibre optics , Wi-Fi that transmit data rapidly. A typical LAN consists of two or more personal computers , printers, and high-capacity disk-storage devices called file servers, which enable each computer on the network to access a common set of files. LAN operating system software , which interprets input and instructs networked devices, allows users to communicate with each other; share the printers and storage equipment; and simultaneously access centrally located processors, data, or programs instruction sets.

This is often achieved by creating an encrypted tunnel for secured end-to-end connectivity. Internet connections. Types of Wireless Networks. In fact, they should be accurately configured for the network to work properly. A client-server network is one n which all available network resources such as files, directories, applications and shared devices, are centrally managed and hosted and then are accessed by client. Network Topology is the representation of a network arrangement, consisting of several nodes i.

Before we discussing about type of network we can discuss about what is a network. In the today world, Two devices are in network if a process in one device is able to exchange information with a process in another device. Networks are known as a medium of connections between nodes set of devices or computers. A network is consist of group of computer systems, servers, networking devices are linked together to share resources, including a printer or a file server. The connections is established by using either cable media or wireless media. A Local Area Network is a privately owned computer network covering a small Networks geographical area, like a home, office, or groups of buildings e. A LAN is used to connect the computers and other network devices so that the devices can communicate with each other to share the resources.

Used for everything from accessing the internet or printing a document to downloading an attachment from an email, networks are the backbone of business today. The smallest and most basic type of network, a PAN is made up of a wireless modem, a computer or two, phones, printers, tablets, etc. These types of networks are typically found in small offices or residences, and are managed by one person or organization from a single device. Enterprises typically manage and maintain LANs. Larger than LANs, but smaller than metropolitan area networks MANs, explained below , these types of networks are typically seen in universities, large K school districts or small businesses.

11 Types of Networks Explained: VPN, LAN & More

A computer network is a group of computers that use a set of common communication protocols over digital interconnections for the purpose 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 topologies. The nodes of a computer network may include personal computers , servers , networking hardware , or other specialised or general-purpose hosts.

A network protocol is an established set of rules that determine how data is transmitted between different devices in the same network. Essentially, it allows connected devices to communicate with each other, regardless of any differences in their internal processes, structure or design. Network protocols are the reason you can easily communicate with people all over the world, and thus play a critical role in modern digital communications. Neither local area networks LAN nor wide area networks WAN could function the way they do today without the use of network protocols.

There are various types of computer networks available. We can categorize them according to their size as well as their purpose. The size of a network should be expressed by the geographic area and number of computers, which are a part of their networks.

What Are the Different Types of Network Switches?

Computer networking

A network consists of two or more computers that are linked in order to share resources such as printers and CDs , exchange files, or allow electronic communications. The computers on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams. It is generally limited to a geographic area such as a writing lab, school, or building. Computers connected to a network are broadly categorized as servers or workstations. Servers are generally not used by humans directly, but rather run continuously to provide "services" to the other computers and their human users on the network.

Setting up a computer network is a fast and reliable way of sharing information and resources within a business. It can help you make the most of your IT systems and equipment. Storing information in one centralised database can also help you reduce costs and drive efficiency. For example:. You can reduce errors and improve consistency by having all staff work from a single source of information.
