COB 204 Lecture Notes - Lecture 6: Simple Mail Transfer Protocol, Transmission Control Protocol, File Transfer Protocol
Document Summary
Network standards- allow diferent systems to work together standard and protocol basically mean the same ethernet, tcp/ip, wi-fi, bluetooth, rfid, wap, etc. Transmission control protocol/internet protocol: common worldwide standard for the internet, four or ive layers (physical layer) Hypertext transport protocol (http: between browser and web server. Simple mail transfer protocol (smtp) for email transmission. File transfer protocol (ftp)- used to move iles over the internet. Wi-fi ideniies any network based on the 802. 11 standard that facilitates wireless communicaion, 300 t radius. Bluetooth deines how two bluetooth devices use short-range radio waves to transmit data. Wimax (ieee 802. 16)- can cover a 30 mi radius, two types are ixed wireless and mobile wireless, broadband internet. Wap (wireless applicaion protocol)- speciies how some mobile devices can display the content of internet services. Modem- modulator demodulator, device that translates digital signals into analog form and vice versa.
