All protocol architectures that have ever been created offer multiplexing and demultiplexing features. The source port number field and the destination port number field are two unique fields that UDP and TCP use to conduct the demultiplexing and multiplexing tasks in the segment headers.Multiplexing is the act of assembling data from several application processes of ...
Computers or devices require IP addresses to communicate on the network. In today’s world, there are numerous network types available, including the internet, intranet, local area network, wide area network, storage area network, and so on. To communicate on those networks, each device requires an IP address. We can manually or automatically assign an IP ...
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 ...
A Wireless Sensor Network (WSN) is a network of small, autonomous devices equipped with sensors that monitor and collect data from their surroundings. They communicate wirelessly, enabling data collection, analysis, and transmission. WSNs are used in a variety of fields, including environmental monitoring, industrial automation, healthcare, and smart infrastructure. What are Wireless Sensor Networks (WSNs)? ...
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 ...
Web browsers and servers each play a unique role in interacting with the internet. A web browser, such as Chrome or Firefox, is a tool that allows users to explore websites and view their content. On the other hand, a web server is a remote computer that hosts websites and distributes their content to browsers, ...
A protocol hierarchy in computer networks refers to the organization and arrangement of networking protocols in a layered structure. This layered approach helps in achieving interoperability, modularity, and ease of implementation and maintenance within complex network systems. The most well-known protocol hierarchy is the OSI (Open Systems Interconnection) model, which consists of seven layers. You ...
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 ...
Computer networks rely on various communication methods to transmit data between devices efficiently. Unicast, broadcast, and multicast are the three basic communication methods. Each method serves a specific purpose in distributing information across a network. Unicast allows two devices to communicate privately, broadcast sends data to all devices in a network segment, and multicast efficiently ...
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 ...
