Network Fundamentals

Network fundamentals refer to the basic principles that enable devices like computers and smartphones to communicate with each other. This involves understanding how data is transmitted through networks using protocols (rules), how devices are connected via wired or wireless links, and how information is routed from one device to another. Key components include routers, switches, and servers, which direct traffic and store data. Networks can be local (within a building) or wide (across countries). Essentially, network fundamentals ensure devices can share information efficiently, reliably, and securely, forming the backbone of modern digital communication.
