Different Types of Communication Devices

Introduction

There are two types of communication devices. They are wired devices or wireless devices. On this page, I will give you some of the ones in which people struggle on the most and to help you out even more. I will put two categories, one being wired devices and the other being wireless devices.

Wired Devices

Data Terminal Equipment (DTE) - Data Terminal Equipment, or otherwise known as DTE is a computer or could be a communication device that generates its final destination of data. DTE's do not communicate with each other, to do so they would need to use a DCE (Data Circuit Terminating Equipment) to carry out the communication. The DTE doesn't need to know how data is sent or received, the communications details are left to the DCE.

Data Circuit-Terminating Equipment (DCE) - The DCE would be your typical modern or any other communication device. This provides connection for the DTE into a communication network and back again. This also terminates and provides clocking (the clock rate determines the speed of the link) for a circuit. The DCE performs functions such as signal conversation, coding and line clocking when working in a data station.

Wireless Devices

3G - 3G stands for 'Third Generation' and this means that it is the third type of access to technology. All mobile network operators in the UK do offer 3G services and of course, all mobile phone manufacturers offer 3G phones that can use all sorts of services. 3G allows downloads to happen with speeds of up to 7.2Mbps (Megabits per Second), which gives the capacity to download content like music, games and of course, apps.

GPRS - GPRS stands for "General Packet Radio Service". This enhances 2G phones to send and receive data more rapidly. With a GPRS connection, your phones is always "on" and is therefore able to transfer data immediately. In other words, this is the signal that you need in order to send and receive data.

Mobile Phones - A mobile phone is basically a mini computer as it is small, hand-held and pretty much does what a computer can do. It can send and receive data and it can also display videos, pictures and can pretty much keep you connected to social networking sites.
	Laptop - A laptop is a personal computer that has been produced because people wanted to be able to work anywhere, whether it was at home or school or even at a friend's house. A laptop combines the components and has inputs of a normal desktop computer that would include speakers, screen display and a keyboard.

Netbook - A netbook contains the main features from a desktop computer. It will also have things like Microsoft Word and other programmes but netbooks are not intended for keeping data as it has a low RAM and Hard Drive Storage. Networks also have limited power as their batteries are smaller than a desktop computer. Netbooks are however cheaper and you can easily replace parts as they are also cheap, not to mention that you can carry it around.
