You are watching: To create a computer network, you must have at least two computers.
The home network or small area network enables multiple devices e.g. PCs,tablets and so on to connect to every other, and also to attach to the internet.
In this tutorial you will learn just how you to build and also setup a home or tiny area network and also connect it to the Internet.
Choosing a Wired or Wireless Network
Do You construct a wired or Wireless Network? i beg your pardon is best?
Early (pre 2008) residence networks to be predominately wired networks.
Wired networks use Ethernet end UTP cable and also tend come be quicker than wireless networks, which is critical consideration if you are a gamer. The simple wired home network diagram listed below shows a minimum setup v a switch and broadband router.
It Is finest used because that network backbone i.e. Connecting in between router,network switches and also wireless accessibility points on various levels (floors).

Home Wireless Networks
Wireless networks usage Wi-Fi. and are quick and easy to install, however are typically slower than wired networks. Check out Wi-Fi and Wireless networks for more details.Wireless Network AdvantagesEasy come setup indigenous an end user perspective.Allows easy access to clever phones, Tablets and mobile devices.No cables to run.Wireless Network Dis-AdvantagesNot as Secure as wired networks without suitable configuration, and also easy come setup insecurely.Not as rapid as wired networks.Not as reputable as wired networks.Main Uses
Connecting peripheral tools like computers,smart phone,tablets etc.
Most home networks will usage a mixture of wired and also wireless.
Setting up a home Network -Components and also Structure
Today but most residence and small home office networks will usage a wireless network or combined network, as most human being use clever phones, and tablets which don’t have Ethernet support.
The main materials required to construct a common home/small office network are:Router or Wireless router – associate the network come the Internet.Wireless access Point – used to affix Wi-Fi equipped gadgets to the network.Ethernet HUB or Switch -Used to affix Ethernet fitted devices.Cable cat 5, cat5e or cat 6 with RJ45 connectors.Telephone Cable v RJ 10 connectors.Broadband Filters.
The home network diagram below shows the structure of a typical little home network
For most residence networks the Wireless Router or Hub which connects the network to the web will be the main component that the house or little home office network, and also in many situations it will certainly be the only component.
The Wireless router generally incorporates a Wireless accessibility point,Ethernet switch, DSL modem and also Router in a solitary box.
This short video shows just how to use a Wireless house Hub ( BT) or router come create a residence network the is connected to the Internet.
DSL Modem– switch digital signals into analogue signals that are perfect for sending out over a call line. That is usually constructed into the Internet/broadband router and is not usually purchased together a separate component.

Because the Wireless Router provides the Wireless access point climate you should location it in a central location, if possible, to get the best wireless reception.
Don’tHide it in a cupboardInstall it behind the sofainstall next to motors,microwaves,cordless telephones
Testing her Wireless Signal
The easiest way of experimentation you signal stamin in various locations is to use the inSSIDer Wi-Fi checker which is an application that you can install on your Android tablet computer or phone.

The gadgets then attach without requiring you to get in a password. See Wiki on WPS
Home Network IP Addresses
All of your tools will need an IP address.
This is provided automatically by a business called DHCP which, by default, is listed by the house router.
IP address detailed by the DHCP server are well-known as dynamic addresses, as they deserve to change. You can additionally assign addresses manually, and these are well-known as static addresses.
Static Addresses space not usually assigned yet are often compelled when making use of Port forwarding.
They deserve to be assigned top top the network setups of the device, however preferably top top the DHCP server using reserved addresses.
Additionally the addresses used on your residence network are well-known as internal addresses.
When you attach to the web your maker will usage an external IP address. This address is the IP address of the router/hub. See internal vs outside IP addresses because that a much more detailed explanation.Finding her DNS, IP, MAC Addresses and also Router IP Addess
You may need to uncover out what DNS servers you room using or the IP or MAC resolve of:Your home Router.Your very own computer/tablet/phone
The main tool you use is the ipconfig (windows) or ifconfig (linux) tool.
The display screen shot listed below shows the ipconfig command use with the /all switch. I.e. ipconfig/all

A computer system with a Gigabit network map talking to a computer system with a 100Mbit/s network card is restricted to 100Mbit/s.
Shared devices like switches and Wireless access points space network throttle points similar to traffic lights and roundabouts ~ above a road.
LAN speed test is a very useful tool for testing your regional network speeds. Check out understanding home network speeds.
For net speeds you deserve to use online speed test sites. View Understanding internet speeds and speed tests.
