A MAC address, or Media Access Control address, is a unique hardware address assigned to network interfaces, such as network interface cards (NICs) and Wi-Fi adapters. This address is used for identifying devices on a network at the data link layer of the OSI model. Every network-capable device, whether it’s a computer, smartphone, router, or […]
Packet switching is a fundamental technique used in computer networking to transmit data over digital networks, including the Internet. It is a method of data transmission that divides digital information into small, standardized units called packets. These packets are individually routed from the source to the destination and can take different paths through the network. […]
A switch, in the context of computer networking, is a crucial network device that operates at the data link layer (Layer 2) of the OSI (Open Systems Interconnection) model. It is used to connect multiple devices within a local area network (LAN) and efficiently manage the flow of data by determining how to forward data […]
Logical topology refers to the way data is transmitted between devices on a network, regardless of the physical layout or arrangement of the devices. It defines how data packets move through the network, how devices communicate, and how they share resources. Logical topology is often contrasted with physical topology, which deals with the physical placement […]
