CompTIA Network+ Exam Review

Answer - A - Packet switching is a network communication method that groups all transmitted data- irrespective of content, type, or structure-into suitably-sized blocks, called packets.

Key Takeaway: Packet switching packages data in specially formatted units (packets) that are typically routed from source to destination using network switches and routers. Each packet contains address information that identifies the sending computer and intended recipient. Using these addresses, network switches and routers determine how best to transfer the packet between hops on the path to its destination. The network over which packets are transmitted is a shared network that routes each packet independently from all others and allocates transmission resources as needed.
