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 ...
Digital and electronic signatures authenticate a document’s legitimacy online, but their security levels and methodologies differ. Encryption is used in digital signatures to protect the document’s integrity and the signer’s identity. An electronic signature, on the other hand, is a larger word that encompasses a variety of approaches, such as inputting a name or utilizing ...
A computer network is a set of connected devices. Devices are connected through a link. In the computer network, devices can transmit data and information using protocols. The Internet is the biggest example of a network that connects devices globally and allows the transmission of data and information from anywhere in the world.The major terminology ...
Regarding web addresses and links, terminology like URI and URL are frequently used interchangeably. They do, however, have distinct meanings and purposes. A URI is similar to a general name for any resource, whereas a URL is a sort of URI similar to a specific location for a resource. URLs are more specific since they ...
Network simulators and network emulators are used in the research work of the computer network. A network simulator is a tool or software program that allows for analyzing the relationships between different components connected in the network. What is a Network Simulation? Network Simulator Network simulation is one of the methods used in computer network ...
Network layer design involves key challenges: routing, addressing, and forwarding. Routing protocols determine paths for data packets, balancing efficiency and reliability. Addressing assigns unique identifiers to devices. Forwarding directs packets based on addresses. Quality of Service (QoS) ensures performance levels. Security must safeguard data. Scalability addresses growth. Interoperability supports different technologies. Congestion control manages data ...
MIME in computer networks stands for Multipurpose Internet Mail Extensions. MIME is an extension of its parent protocol i.e. SMTP (Simple Mail Transfer Protocol). MIME protocol is not restricted to textual data only. With the help of the MIME protocol, we can send various types of data through the internet such as text, images, audio, ...
For sending the packet to its destination we must be aware of the source MAC address and destination MAC address and source and destination IP address. The packet will be directly delivered if the destination is available in the same network otherwise the packet is sent to the default gateway first. Introduction For the successful ...
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 ...
