Prefix
Prefix: An IP addressing scheme that indicates the network portion of the address. It determines how many of the leading bits will represent the network address, and the remaining bits will represent the host. In an IPv6 address, for example, a /64 prefix indicates that the first 64 bits of the address are the network […]
Presentation Layer
Presentation Layer: The sixth level in the seven-layer Open Systems Interconnection (OSI) model, which standardizes functionalities of networking or telecommunication systems. This layer ensures that the data transmitted between systems is in a usable format and is responsible for tasks such as data compression, encryption, and translation of network data into a format that can […]
Port Address Translation (PAT)
Port Address Translation (PAT): A technique used in networking to enable multiple devices on a private network to share a single public IP address. It is commonly used in home and small business networks to conserve IP addresses and improve network efficiency. For example, a router using PAT can allow multiple devices on a home […]
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.
