Network technologies: Understanding PANs, HANs, modems, routers and ISPs
- 1. Network technologies: Networks Gr10 J Wepener 215001030 Y de Beer 201334957
- 2. Introduction: • What types of internet connections do you know of? • Which internet connections do you get e.g. PAN • Where does a modem get its internet connection from? • How is internet signals transferred from the modem to the computer? • When will internet connections be available?
- 3. Personal area network (PAN) / Home area network (HAN) - What is it? / What is it used for? • What is it? • A PAN is a personal Area Network - computer network used for data transmission amongst devices such as computers, telephones, tablets and personal digital assistants. • What is it used for? • PAN’s can be used for communication amongst the personal devices themselves (interpersonal communication), or for connecting to a higher level network and the Internet (an uplink) where one "master" device takes up the role as internet router.
- 4. Personal area network (PAN) / Home area network (HAN) - What is it? / What is it used for? • What is it? • A home area network (HAN) is a network that is deployed and operated within a small boundary, typically a house or small office/home office (SOHO). • What is it used for? • A home area network (HAN) is a network contained within a user's home that connects a person's digital devices, from multiple computers and their peripheral devices to telephones, VCRs, televisions, video games, home security systems, smart appliances, fax machines and other digital devices that are wired into the network.
- 5. Disadvantages and Limitations of PAN’s and HAN’s • Health Issue: •Expensive: •Lack of Wi-Fi Password: •Slow internet provision:
- 8. ISP: Definition & Purpose • ISP = Internet service provider • An organisation that provides access to the internet • Via connection of cable or DSL • E.g. Telkom, Vodacom, CellC, MTN, MWeb etc. • Outline of internet connection: • PC or Wireless device • Router • Modem • ISP • Internet

- Health Issue: devices are mostly used for communication. wireless uses microwave signals as medium for communication path. In Long time working with radius signals leads to some brain and heart related problems. Expensive: This network uses devices may be expensive such as: smartphones, laptops, Digi camera, PDA... etc. Lack of Wifi Password: If the Wi-Fi password is easily guessed any body within the range can steel Internet access and resources on the network. Slow internet provision: When internet service is down When modem/router is low on data When internet service signal is weak/ distorted
- Accessibility: A better way to gives accessibility for all the devices in the network Thus, better Internet connection access. Management: The resources on this network can be: managed and controlled data usage also can be managed. Security: It enhance the home network security and reliability. Internet network also password protected. It can support MAC Address filtering – thus, Internet can be accessed by authorised people only. Resources sharing: Resources on the network can be shared over network. such as: files, folders, printers, faxes etc.. Multiuser: Multiple users can access the network resources such as Internet, shared devices, files etc simultaneously. Life Style: It enhances the quality of life and home with digital communication.
- In order for device to be connected to the internet the router must be connected to the modem. Routers have specific Ethernet ports designed to connect to Ethernet port of a cable /DSL modem. Routers = small box that allows multiple computers (devices) to join the same network Modem = device that provides access to the internet. Modems supply internet via Cable or DSL ( wireless).
- Conclussion A PAN is a Personal Area Network A HAN Home are Network Health Issue: Expensive: Lack of Wi-Fi Password: Slow internet provision: Accessibility: Management: Resources sharing: Multiuser: Life Style: Routers, modems and swithes ISP = internet service provider – e.g. Telkom, MTN , mweb etc. Class will continue next week
