1.2 Network Architecture and Basic Concepts
Network architecture is the overall design of a computer network. It shows how computers, servers, and other devices are arranged (as shown in Figure 1.2). It also defines how data is transmitted across the network. Network architecture includes hardware, software, and communication rules. A good architecture helps the network work efficiently. It also supports future expansion of the network.

CLASS ACTIVITY
lightbulbProvide pictures or names of devices. Students match device names with functions. Discuss answers
A network works by sending data from one device to another. Data is broken into small packets before transmission. These packets travel through cables or wireless signals. Networking devices guide packets to the correct destination. The receiving device reassembles the packets into the original data. This process allows smooth and fast communication.
