Devices for Network Connection

For this assignment I have been asked to write about the hardware and software components which are used to connect to the internet securely and safely, which facilitate communication and representation for users.


A wireless router is when internet data comes through the router from the phone line and is converted into radio signals. The signal is then picked up by the network card in your computer and is then translated into internet data again. For example BT Home Hub.

 A cable router lets the cable device act as a connection between two different networks. The cable company has one network and the other is your computer, the cable router allows these two to networks to connect and share information with each other.

3G/4G

3G or 3rd generation telecommunications is a generation of standards for mobile phones. It is mostly used with mobile phones and handsets which can connect to the internet meaning you can download or puload data to and from the internet. With 3G you can intereact with each other through video call. Your phone will have two cameras which will be at the front and back and having 3G allows you to see each other during a phone call.


4G is the 4th generation of cellular mobile wireless standards. It is a successor to the 3G and 2G families of standards. When out instead of having to topup and get access to the internet, 4G lets you access the internet when you are out instead of accessing it from home. You have high speed conncetion to the internet and the convenience of being online all the time. The best news of 4G is that it is constantly faster.


Bluetooth/Wireless

Bluetooth is an open wireless technology standard for exchanging data over short distances (using short wavelength radio transmissions) from sixed and mobile devices creating personal area networks (PANS) with high levels of security.



Network Interface Cards

Is a device that a computer uses to participate on a computer network. It allows users to connect with each other by using cables or wirelessly.
