25 Network Communication Standards 25
26 Standards are guidelines Dictates the way computers access the medium Physical cable and/or wireless technology used. 26
27 Network Communication Standards Ethernet: Kind of standard No central command No special device on the network (No control) Transmit data based on availability 27
28 Network Communication Standards TCP/IP: Transmission Control Protocol Internet Protocol It is a network standard that takes care of Messages, Data The way they are routed Makes sure that data travels correctly. 28
29 Start All Programs Accessories Command Prompt C:\ Type: IPCONFIG Enter 29
30 Wi-Fi: It is a network standards Determines how two wireless devices communicate to each other. Over the air Communicate with each other is important. Faster data transfer is expected Many computers and devices can connect in one time. 30
31 Bluetooth: It determine the way Bluetooth devices communicate with each other. They use short-range radio waves to transmit data. It is just for limited data transfer between two devices, It can transfer data among devices without any cable or wire. Jadi, Jimat Cable la kawan kawan!! 31
32 WiMax: Wide Interoperability for Microwave Access, It is developed by IEEE: "Institute of Electrical and Electronics Engineers." Its job is to specify how wireless devises communicate in a wider area. WiMax provides wireless broadband Internet access. 32
33 Network Communication Standards 33
34 Network Communication Standards A single station can serve hundreds of users Weather conditions like rain can interrupt the signal 34
35 WAP Wireless Application Protocol Determines how wireless devices like smart phones and PDA's can show contents of Internet 35
36 What Is Communication Software? use your computer to speak to others over the internet or your local office computer network. 36
37 Communication software: It is an application It is a program designed to pass information From one computer to another computer. 37
38 It helps users to access remote computers and transfer files in different formats Example: (FTP), File Transfer Protocol Messaging Software , Chat, Voic , Skype 38
39 CAS: Collaborative Applications Software allows networked computer users to work together on related tasks via local or remote servers. Server Software Door Access System Finger Print and attendance software 39
40 What Is Home Network 40
41 It is a residential Network (LAN) local area network To communicate between devices in the home, Such as Personal Computers Accessories, Printers Mobile computing devices 41
