Presentation transcript:

 TCP/IP is the communication protocol for the Internet  TCP/IP defines how electronic devices should be connected to the Internet, and how data should be transmitted between them  TCP is for communication between applications  TCP is responsible for breaking data down into IP packets  IP is for communication between computers  IP is responsible for routing each packet to its destination

 Each computer must have an IP address before it can connect to the Internet  An IP address contains 4 numbers. The numbers are between 0 and 255. Addresses are written as four numbers separated by a period:  TCP/IP uses 32 bits or 4 bytes addressing  IP numbers are hard to remember. Using a domain name is easier:

 TCP/IP is a large collection of different communication protocols based upon the two original protocols TCP and IP  HTTP takes care of the communication between a web server and a web browser  HTTPS takes care of the secure communication between a web server and a web browser  SSL (Secure Sockets Layer) is used for encryption of data for secure data transmission

 SMTP (Simple Mail Transfer Protocol) is used for transmission of s  MIME (Multi-purpose Internet Mail Extensions) lets SMTP transmit multimedia files  IMAP (Internet Message Access Protocol) is used for storing and retrieving s  POP (Post Office Protocol) is used for downloading s from an server to a PC  FTP (File Transfer Protocol) takes care of transmission of files between computers

 When you write an , you use an program like Outlooks, Lotus Notes  Your program uses deferent TCP/IP protocols:  Send your s using SMTP. SMTP can transmit pure text. SMTP uses the MIME protocol to send binary data  Download your s from an server using POP  Connect to an server using IMAP
