Computer Concepts Module 10 Practice Exam

The common set of rules for exchanging information between devices on a network is a protocol. A protocol defines how data is formatted (syntax), what meaning the bits convey (semantics), and how devices coordinate timing and control signals (timing). This standardization lets different devices and software communicate reliably, even if they’re from different vendors. For example, the HTTP protocol governs how web browsers request pages and how servers respond, including which messages are sent, how errors are indicated, and how sessions are managed. Topology describes the network’s layout, bandwidth is the capacity of the connection to carry data, and latency is the delay in data travel. These are important considerations, but they don’t define the actual rules for exchanging information—that’s the role of a protocol.
