By the end of the lesson you should be able to: Describe various internet connectivity requirements

• Data Terminal Equipment(DTE) : Are devices that transform the user input into a digital signal and back to analogue signal
• Transmission media: are physical or wireless channels used to transmit data and information from one point to another
• Telecommunication cables: modems are used to dial up a remote computer via a telephone line to connect to the internet. Modems stand for Modulator Demodulator. A modem modulates(converts) outgoing digital signals to analog forms for transmission on the copper cable
• satellite transmission : 
• internet service provider
• software e.g Internet protocol, browser, e-mail client. Internet Protocol defines the format of packets and provides an addressing system. The Internet Protocol just delivers them. It's up to another protocol, the Transmission Control Protocol (TCP) to put them back in the right order.
• wireless telecommunication: Mobile telecommunication Industry uses Global System for Mobile Communication(GSM)
• GSM uses various technologies to connect mobile devices wirelessly e.g  General Packet Radio Service(GPRS), LTE,EDGE ,and UTMS
