What is the primary function of IPX/SPX protocols?

The primary function of IPX/SPX protocols lies in their role as networking protocols, specifically designed to facilitate communication over a network. IPX (Internetwork Packet Exchange) and SPX (Sequenced Packet Exchange) were developed by Novell for use in their NetWare operating systems.

IPX is responsible for routing packets across different networks, while SPX operates at a higher level, managing packet sequencing and ensuring reliable data transfer between applications. Together, they support the establishment of network connections, data transfer, and ensure that data sent over the network arrives reliably and in the correct order.

This functionality encapsulates the essence of what networking protocols do, as they govern how data is formatted, transmitted, and communicated over a network, ensuring that devices can interact effectively within a local network or across multiple networks. The emphasis on enabling inter-device communication and data management is what classifies IPX/SPX as essential networking protocols.
