DHCP, or Dynamic Host Configuration Protocol, is a network protocol used to automatically assign IP addresses to devices on a network. DHCP is used mostly in networks where devices are not permanently assigned an IP address, such as in home and small office networks. DHCP works by assigning a temporary IP address to each device… Read More

DF – Don’t Fragment is a very important rule when it comes to networking. It ensures that packets are not fragmented and that they are sent in one piece. This is especially important for real-time applications such as VoIP or video streaming. Fragmentation can cause all sorts of problems, from packet loss to jittery audio… Read More

DES, or the Data Encryption Standard, is a widely-used method for ensuring data security. DES uses a 56-bit key to encrypt and decrypt data, making it relatively secure against brute force attacks. However, DES has been broken by several research teams and is no longer considered secure against more sophisticated attacks. As such, it is… Read More

DCE is the hardware that connects a computer to a network. It is responsible for terminating the data circuit and providing clocking signals. DCEs are typically found in routers, switches, and other network devices. Without DCEs, data would not be able to flow between devices on a network. DCEs play an important role in ensuring… Read More
