Personal Area Network (PAN)
Personal Area Network (PAN): A network arrangement that interconnects devices within the reach of an individual person, typically within a range of 10 meters. This could include devices such as smartphones, laptops, wearable devices, or smart home devices. The security considerations for a PAN involve ensuring secure communications between devices, controlling access to devices, and […]
Physical addressing
Physical addressing: The process of assigning a unique identifier, such as a MAC address or IP address, to each device on a network. This identifier enables devices to communicate by sending and receiving data, allowing them to be identified and located for communication purposes.
Physical Layer
Physical Layer: The lowest layer of the OSI model, which defines the physical characteristics of a network, such as transmission media, connectors, and signaling methods. It ensures reliable and efficient data transmission across a network. Examples of physical layer components include network cables, network switches, and network adapters.
Ping
Ping: A network utility used to test the connectivity and responsiveness of a networked device or server. It works by sending a small packet of data to the target device and measuring the time it takes for the device to respond. It is used in the field of information technology to diagnose and troubleshoot network […]
Plain Old Telephone Service (POTS)
Plain Old Telephone Service (POTS): A traditional analog telephone system that uses copper wire to transmit voice signals over long distances. It is used in telecommunications to provide basic voice services to customers. Examples include landline phone systems in homes and businesses, payphones, and emergency telephone systems.
Packet Filtering
Packet Filtering: A technique where packets of data are analyzed while they are traversing a network interface. Depending on predefined criteria such as IP addresses, protocols, port numbers, or other packet attributes, the packet filter can block or allow packets to pass through. This is commonly used in firewalls and routers as a basic method […]
