Document Summary

A collection of hardware (servers, printers, cables), software (application, operating system), and people (stakeholder) people are an essential component of a network. Components of communication: sender, receiver, medium, one or more protocols. Protocol: a set of standards and rules by which computers communication. Provides interface between software applications and a network for interpreting applications" requests and requirements. Allows hosts and applications to use a common language; performs data formatting, encryption, and compression. Ensures accurate delivery of data through flow control, segmentation and reassembly, error correction, and acknowledgment. Establishes network connections; translates network addresses into their physical counterparts and determines routing. Packages data in frames appropriate to network transmission method. Manages signaling to and from physical network connections. Osi model: helpful model for understanding & developing computer-to-computer communications over a network or, theoretical representation of what happens between 2 nodes communicating over a network. Separates data into protocol data units (pdus), or discrete amounts of data.
