At its simplest level, networking is a way of transporting and exchanging data between workstations – or nodes – over a shared medium within an internal IT system. A good network solution entails the design and construction of a network, as well as the management, maintenance and operation of the infrastructure on an ongoing basis. In this article, we take a look at the most frequently asked questions about networking solutions.

A computer network, also referred to as a data network, is a series of interconnected nodes that can transmit, receive and exchange data, voice and video traffic. Examples of nodes in a network include servers or modems. Computer networks commonly help endpoint users share resources and communicate. They commonly appear all over the place, such as homes, offices and government administrations. The use of computer networks can overcome geographic barriers and enable the sharing of information. Computer networks enable the usage and sharing of any number of applications and services, including emails, video, audio and plenty of other types of data, over the internet.
A wide area network (WAN) is a large computer network that connects groups of computers over large distances. WANs are often used by large businesses to connect their office networks; each office typically has its own local area network or LAN, and these LANs are connected via a WAN.
A metropolitan area network (MAN) is a computer network that connects computers within a metropolitan area, which could be a single large city, multiple cities and towns, or any given large area with multiple buildings. A MAN is larger than a local area network (LAN) but smaller than a wide area network (WAN).
A local area network (LAN) is a group of computers and peripheral devices that share a common communications line or wireless link to a server within a distinct geographic area. A local area network may serve as few as two or three users in a home office or thousands of users in a corporation's central office.
A personal area network (PAN) is a computer network for interconnecting electronic devices within an individual person's workspace. A PAN provides data transmission among devices such as computers, smartphones, tablets and personal digital assistants.
Computer networking refers to connected computing devices (such as laptops, desktops, servers, smartphones, and tablets) and an ever-expanding array of IoT devices (such as cameras, door locks, doorbells, refrigerators, audio/visual systems, thermostats, and various sensors) that communicate with one another.
Computers need networking hardware in order to connect to each other. Routers, hubs, switches and bridges are all pieces of networking equipment that can perform slightly different tasks. A router can often incorporate hubs, switches and wireless access within the same hardware.
A router is a device that connects two or more packet-switched networks or subnetworks. It serves two primary functions: managing traffic between these networks by forwarding data packets to their intended IP addresses and allowing multiple devices to use the same Internet connection.
Your modem is a box that connects your home or network to the wider Internet. A modem modulates and demodulates electrical signals sent through phone lines, coaxial cables, or other types of wiring. In other words, it transforms digital information from your computer into analog signals that can transmit over wires. It can translate incoming analog signals back into digital data that your computer can understand. Most stand-alone modems have just two ports: one that connects to the outside world, and an Ethernet jack that connects to a computer or a router.
Hubs, bridges and switches are all network connecting devices. A network connecting device is a device that connects two or more devices together that are present in the same or different networks. A network connecting device can be a repeater, hub, bridge, switch, router, or gateway. But in this blog, we'll focus on hubs, switches, routers, and gateways. We'll also learn about their features, advantages, and disadvantages in networking. All these connecting devices operate in some specific layers of the OSI (Open System Interconnection) Model.
Network topology refers to the manner in which the links and nodes of a network are arranged to relate to each other. Topologies are categorised as either physical network topology, which is the physical signal transmission medium, or logical network topology, which refers to the manner in which data travels through the network between devices, independent of the physical connection of the devices. Logical network topology examples include twisted-pair Ethernet, which is categorised as a logical bus topology, and token ring, which is categorised as a logical ring topology.
Physical network topology examples include star, mesh, tree, ring, point-to-point, circular, hybrid, and bus topology networks, each consisting of different configurations of nodes and links. The ideal network topology depends on each business’s size, scale, goals, and budget. A network topology diagram helps visualise the communicating devices, which are modelled as nodes, and the connections between the devices, which are modelled as links between the nodes.
Network performance is the analysis and review of collective network statistics, to define the quality of services offered by the underlying computer network. It is a qualitative and quantitative process that measures and defines the performance level of a given network. It guides a network administrator in the review, measure and improvement of network services.
Modern-day networks deliver more than connectivity. Organisations are embarking on transforming themselves digitally. Their networks are critical to this transformation and to their success. The types of network architectures that are evolving to meet these needs are as follows:
