The document discusses several common network protocols including the Internet Protocol which governs communication between computers. It describes protocols like TCP which specifies how packets are exchanged between networks, IPX/SPX originally used by Novell, and HTTP which governs file exchanges on the World Wide Web. The document also covers protocols for file transfer, secure connections, email delivery, and other functions.

2. INTERNET PROTOCOL
•IT IS A SET OF RULES GOVERNING

COMPUTERS IN A NETWORK.

3. COMMON NETWORK PROTOCOLS
• TRANSMISSION CONTROL PROTOCOL (TCP)
• INTERNET PACKET EXCHANGE/ SEQUENCED PACKET EXCHANGE (IPX/ SPX)
• NETBIOS EXTENDED USER INTERFACE (NETBEUI)
• APPLETALK
• HYPER TEXT TRANSFER PROTOCOL (HTTP)
• FILE TRANSFER PROTOCOL (FTP)
• SECURE SHELL (SSH)
• TELNET
• POST OFFICE PROTOCOL (POP3)
• INTERNET MESSAGE ACCESS PROTOCOL(IMAP)
• SIMPLE MAIL TRANSFER PROTOCOL (SMTP)

4. TRANSMISSION CONTROL PROTOCOL
(TCP)
•REPRESENTS A SET OF PUBLIC
STANDARDS THAT SPECIFY HOW
PACKETS OF INFORMATION ARE
EXCHANGED BETWEEN COMPUTERS
OVER ONE OR MORE NETWORKS.

5. INTERNET PACKET EXCHANGE/
SEQUENCED PACKET EXCHANGE (IPX/
SPX)
•THE PROTOCOL SUITE ORIGINALLY
EMPLOYED BY NOVELL CORPORATION’S
NETWORK OPERATING SYSTEM,
NETWARE.

6. NETBIOS EXTENDED USER INTERFACE
(NETBEUI)
•PRIMARILY ON SMALL WINDOWS NT
NETWORKS.
•CANNOT BE ROUTED OR USED BY
ROUTERS TO TALK TO EACH OTHER ON
A LARGE NETWORK.

7. APPLETALK
•A PROTOCOL SUITE USED TO NETWORK
MACINTOSH COMPUTERS. IT IS COMPOSED
OF A COMPREHENSIVE SET OF PROTOCOLS
THAT SPAN THE SEVEN LAYERS OF THE OPEN
SYSTEMS INTERCONNECTION (OSI)
REFERENCE MODEL.

8. HYPER TEXT TRANSFER PROTOCOL
(HTTP)
•GOVERNS HOW FILES SUCH AS TEXT,
GRAPHICS, SOUND, AND VIDEO ARE
EXCHANGED ON THE WORLD WIDE WEB
(WWW).

9. FILE TRANSFER PROTOCOL (FTP)
•PROVIDES SERVICES FOR FILE TRANSFER
AND MANIPULATION. FTP ALLOWS
MULTIPLE SIMULTANEOUS
CONNECTIONS TO REMOTE FILE
SYSTEMS.

10. SECURE SHELL (SSH)
•USED TO SECURELY CONNECT TO A
REMOTE COMPUTER.

11. TELNET
•AN APPLICATION USED TO CONNECT TO
A REMOTE COMPUTER THAT LACKS
SECURITY FEATURES.

12. POST OFFICE PROTOCOL (POP3)
•USED TO DOWNLOAD E-MAIL FROM A
REMOTE MAIL SERVER.

13. INTERNET MESSAGE ACCESS
PROTOCOL(IMAP)
•ALSO USED TO DOWNLOAD E-MAIL
FROM A REMOTE MAIL SERVER.

14. SIMPLE MAIL TRANSFER PROTOCOL
(SMTP)
•USED TO SEND E-MAIL TO A REMOTE E-
MAIL SERVER.
