A network connects computers, mobile phones, peripherals, and even IoT devices. Switches, routers, and wireless access points are the essential networking basics. Through them, devices connected to your network can communicate with one another and with other networks, like the Internet. Switches are the foundation of most business networks. A switch acts as a controller, connecting computers, printers, and servers to a network in a building or a campus. Switches allow devices on your network to communicate with each other, as well as with other networks, creating a network of shared resources. Through information sharing and resource allocation, switches save money and increase productivity.

A switch acts as a controller, connecting computers, printers, and servers to a network in a building or a campus. Switches allow devices on your network to communicate with each other, as well as with other networks, creating a network of shared resources.

Through information sharing and resource allocation, switches save money and increase productivity. There are two basic types of switches to choose from as part of your networking basics: Routers connect multiple networks together. They also connect computers on those networks to the Internet. Routers enable all networked computers to share a single Internet connection, which saves money. A router acts a dispatcher.

Learn Networking Basics

It analyzes data being sent across a network, chooses the best route for data to travel, and sends it on its way.

Routers connect your business to the world, protect information from security threats, and can even decide which computers receive priority over others. Beyond those basic networking functions, routers come with additional features to make networking easier or more secure. Depending on your needs, for example, you can choose a router with a firewall, a virtual private network VPN , or an Internet Protocol IP communications system.

A wireless network makes it easy to bring new devices online and provides flexible support to mobile workers. An access point acts like an amplifier for your network. While a router provides the bandwidth, an access point extends that bandwidth so that the network can support many devices, and those devices can access the network from farther away.

But an access point does more than simply extend Wi-Fi. It can also give useful data about the devices on the network, provide proactive security, and serve many other practical purposes. Each standard is an amendment that was ratified over time.

Networking Basics: Part 1 - Networking Hardware

The standards operate on varying frequencies, deliver different bandwidth, and support different numbers of channels. To create your wireless network, you can choose between four types of deployment. Each deployment has attributes that will work better for different solutions. Mobility Express is a simple, high-performance wireless solution for small or medium-sized organizations. It has the full complement of advanced Cisco features, which are preconfigured with Cisco best practices.

The defaults allow for a quick and effortless Wi-Fi deployment that can be operational in minutes. It's perfect for small businesses' basic networking. The most common type of wireless network system, centralized deployments are traditionally used in campuses where buildings and networks are in close proximity. This deployment consolidates the wireless network, which makes upgrades easier and facilitates advanced wireless functionality. An example of how a hub works is shown below.

Computer A wants to send a message to computer B. It sends the message through the Ethernet cable to the hub, then the hub repeats the message to all of the connected computers. A network using a hub can slow down if many computers are sending messages, since they may try and send messages at the same time and confuse the hub.

To help with this problem, networks began to use another device called a switch. Instead of repeating all messages that come in, a switch only sends the message to the intended destination. This eliminates the unnecessary repetition of the hub.

Computer Networking Books

Using a switch, computer A sends a message to computer B —the other computers do not see the message. Those computers can send other messages at the same time without interfering. Switches do have a limitation though—they only know about the addresses of equipment that is plugged directly into them.

So, you can only send messages to a small number of devices—however many ports the switch has! If you need to send a message to a computer on another network, it will need to be sent through a router, which we discuss next.

Routers do the majority of the hard work on a network - they make the decisions about all the messages that travel on the network, and whether to pass messages to and from outside networks. There are three main functions:. Routers separate networks into sections, or bridge different networks together, as we see in the example above—the private network of They can assign IP addresses.

In the example of They can filter messages or keep users out of private networks. Most routers have a Firewall built in. This is a software function that keeps unwanted messages from reaching the computers on the inside, or private part, of the network. Let us take another look at As it turns out, that postal service building is acting as a Router.

In this case, the postal service building is routing messages between the rest of the Internet using its public address and the street with private addresses. This module is intended to provide some helpful background on networking. We recommend reading the upcoming but not finished! Learn about Wireless after this guide. Introduction This document covers the basics of how networking works, and how to use different devices to build networks.

This module covers the concepts of: Clients and servers—how services such as e-mail and web pages connect using networks. IP addresses—how devices on a network can be found.

Network hubs, switches and cables—the hardware building blocks of any network. Routers and firewalls—how to organize and control the flow of traffic on a network. Clients and Servers An important relationship on networks is that of the server and the client. What is one real world example of a client and server relationship: Below we can see On it are three houses: Find the IP addresses assigned to your computer, and your network.

What is the IP address for your computer? Network Hubs and Switches Traditionally, computers are connected to each other using cables—creating a network. Routers and Firewalls Routers do the majority of the hard work on a network - they make the decisions about all the messages that travel on the network, and whether to pass messages to and from outside networks.

There are three main functions: Separate and Bridge Routers separate networks into sections, or bridge different networks together, as we see in the example above—the private network of Firewall and Protect They can filter messages or keep users out of private networks.

Ethernet A type of networking protocol—it defines the types of cables and connections that are used to wire computers, switches, and routers together. Most often Ethernet cabling is Category 5 or 6, made up of twisted pair wiring similar to phone cables.
