Some people use the words “internet” and “World Wide Web” interchangeably. They believe they are the same, although this is not the case. The difference between the Internet and WWW (World Wide Web ) is essential to understand. WWW or web is one of the key services offered by the internet. The World Wide Web, ...
A VPN (virtual private network) is a service that establishes a secure, encrypted online connection. A VPN establishes a virtual connection between your device and a distant server managed by a VPN service. This connection establishes a secure point-to-point tunnel that encodes your personal information, conceals your IP address, and enables you to bypass online ...
A bridge is a network device that joins multiple subnetworks to form a large single network. It offers interconnection to other computer networks that employ the same protocol. Multiple LANs (Local Area Networks) can be linked via a bridge to build a more extensive LAN. Bridges operate at the data link layer, the second layer ...
A telecommunications network is a collection of nodes linked together by telecommunications links that allow the nodes to exchange messages. The links may employ several technologies to transmit messages and signals based on circuit switching, message switching, or packet switching approaches. The public switched telephone network (PSTN), the Internet, computer networks, and wireless radio networks ...
Data link layer protocols are classified according to whether the transmission channel is noiseless or noisy. Noiseless is an ideal or perfect channel where no frames are lost, duplicated, or corrupted. In contrast, a noisy channel indicates that there will be a lot of disruption in the path when data is transmitted from the sender ...
The Native VLAN functions as a conduit for untagged data across a trunk port. If untagged data arrives at a trunk port, the switch inherently assigns it to the native VLAN. The Native VLAN refers to the default VLAN for an Ethernet trunk (a link or port that carries traffic for multiple VLANs) when no ...
Circuit switching is a connection-oriented service that sends and receives data via a dedicated path. In circuit switching, it is necessary to establish an end-to-end path before delivering any data from the source to the destination. Due to the dedicated circuit path, circuit switching has the lowest probability of data loss. Still, a lot of ...
Internetworking is defined as a way to connect multiple forms of computer networks. A computer network is defined as the interconnection of two or more computers. Computer internetworking occurs when several computer LANs, WANs, or parts of a computer network are linked together using devices such as routers and coordinated through a logical addressing system ...
An IP address is a numeric identifier assigned to a computer within a network that uses the Internet Protocol for communication. This address uniquely identifies a host or a network interface and enables targeted communication to a particular destination. The ISP (Internet Service Provider) assigns an IP address, which is the logical identifier for a ...
IP routing, or Internet Protocol routing, is the process of determining the optimal path for data packets to travel from the source to their destination over an IP-based network. This network could be a local network or the worldwide Internet. IP routing involves using routing algorithms and protocols to decide how to forward data packets ...
