IT Networking

Networking solutions aid in dealing with advanced technical solutions. FSIkenya steps in here to provide future-proof networking solutions to deal with the expectations in terms of resilience, security, manageability, robustness, network visibility and economically. There is the creation of customer-specific network infrastructure and their maintenance. The networks that are enabled in a firm today have more complexity and bandwidth but also are highly reliable.

Types of networking

There are two primary types of computer networking.

1. wired networking

2.wireless networking.

Wired networking requires the use of a physical medium for transport between nodes. Copper-based Ethernet cabling, popular due to its low cost and durability, is commonly used for digital communications in businesses and homes. Alternatively, optical fibre is used to transport data over greater distances and at faster speeds, but it has several tradeoffs, including higher costs and more fragile components.

Wireless networking uses radio waves to transport data over the air, enabling devices to be connected to a network without any cabling. Wireless LANs are the most well-known and widely deployed form of wireless networking. Alternatives include microwave, satellite, cellular and Bluetooth, among others.

It should be noted that these types of networking concern the physical layer of the network. Networking can also be classified according to how it’s built and designed, encompassing approaches that include software-defined networking (SDN) or overlay networks. Networking can also be categorized by environment and scale, such as LAN, campus, WAN, data centre networks or storage area networks.

Components of networking
Computer networking requires the use of physical network infrastructure including switches, routers and wireless access points and the underlying firmware that operates such equipment. Other components include the software necessary to monitor, manage and secure the network.

Additionally, networks rely on the use of standard protocols to uniformly perform discrete functions or communicate different types of data, regardless of the underlying hardware.

For example, voice over IP (VoIP) can transport IP telephony traffic to any endpoint that supports the protocol. HTTP provides a common way for browsers to display webpages. The internet protocol suite, also known as TCP/IP, is a family of protocols responsible for transporting data and services over an IP-based network.

Routers in Network

A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. Data sent through the internet, such as a web page or email, is in the form of data packets. A packet is typically forwarded from one router to another router through the networks that constitute an internetwork (e.g. the Internet) until it reaches its destination node.

A router is connected to two or more data lines from different IP networks. When a data packet comes in on one of the lines, the router reads the network address information in the packet header to determine the ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey.

The most familiar type of IP routers is home and small office routers that simply forward IP packets between the home computers and the Internet. An example of a router would be the owner’s cable or DSL router, which connects to the Internet through an Internet service provider (ISP). More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fibre lines of the Internet backbone.

Switches in Network

A network switch is a multiport network bridge that uses hardware addresses to process and forwards data at the data link layer (layer 2) of the OSI model. Some switches can also process data at the network layer (layer 3) by additionally incorporating routing functionality. Such switches are commonly known as layer-3 switches or multilayer switches.
