[ What is ] We Use Different protocols for different operating system

What is Protocol?

A uniform set of rules that enable two devices to connect and transmit data to one another. Protocols determine how data are transmitted between computing devices and over networks.

Different protocols for different operating system:

TCP/IP (Windows)

• Uses Address Resolution Protocol (ARP), router sends ARP request broadcast, matching device (matching IP) sends their MAC address, router then stores this in ARP Cache.
• To Route: must have IP address of sender/receiver/next router
• Very flexible and interoperable (multiple Operating Systems)
• Domain Name Services (DNS): host names resolved from IP addresses

IPX/SPX (Novell Netware)

• Internetwork Packet Exchange/Sequenced Packet Exchange
• IPX handles routing/addressing, only change is IPX network address
• Routing Protocols: RIP and NLSP
• Microsoft's version called NWLink
• Only devices that have names are NetWare servers. (64 characters, not case sensitive, can't use "illegal" characters)

AppleTalk / TCP/ IP (Mac)

• AppleTalk version 2.0 supports Ethernet
• AppleTalk Filing Protocol (AFP): provides interface between application and a file server.
• AppleShare is the Mac service offered to implement AFP service
• Services for Macintosh: makes multi client support possible (as shared folder or Macintosh volume).
