Stack organization refers to a computer architecture where memory is managed in a Last-In-First-Out (LIFO) structure. It’s commonly used for function calls and local variables. The stack contains data such as return addresses and values, aiding program flow. This organized approach simplifies memory management and improves efficiency in execution. What is a Stack Organization? Stack ...
Robert Metcalfe and others developed the Ethernet protocol at Xerox PARC in 1973 as a wired communication protocol that links computers over a network. This is a widely used LAN protocol, also called Alto Aloha Network. A wide area network and an original area network are connected by it. What is Ethernet? Ethernet in computer networks refers ...
MAC address is the physical address, which uniquely identifies each device on a given network. To make communication between two networked devices, we need two addresses: IP address and MAC address. A physical address that operates at the Data Link Layer is called a Media Access Control Address. It is assigned to the NIC (Network Interface card) of ...
Essential for connecting devices to broader networks, access networks underpin services like Internet, VoIP, and video streaming. Blending wired and wireless technologies is vital for personal and enterprise use. Maintained by ISPs, these networks continuously evolve, incorporating technologies like FTTH to enhance speed and reliability. What Does an Access Network Do? Before the employment of ...
Until the introduction of software-defined networking (SDN), a class of technologies that separates the network control plane from the forwarding plane to enable more automated provisioning and policy-based administration of network resources, hardware ruled the networking industry. The most accurate definition of SDN is the technology that separates the management of network devices’ control planes from the underlying data ...
Using methods or technologies that operate on a network, Quality of Service (QoS) ensures the performance of crucial applications even when the network’s capacity is constrained. Giving particular high-performance applications priority enables companies to modify the volume of network traffic as a whole. Networks that transmit traffic for resource-intensive systems frequently use QoS. Internet protocol television (IPTV), ...
ICMP works like the communication between the carpenter and the store. It relays messages from the receiver to the sender about the data that was supposed to arrive. ICMP protocol notifies the sender if the data is not received by the receiver or received in the wrong order. Thus, ICMP is a protocol for communicating ...
Digital signatures allow us to verify the author, date, and time of signatures and authenticate the message contents. To verify the integrity and validity of digital messages and documents, it employs a cutting-edge mathematical technique. It helps us combat the issue of impersonation and tampering in digital communications and ensures that the contents of a message are ...
Integrated Services Digital Network (ISDN) comprises communication standards facilitating the concurrent digital transmission of voice, video, and data over traditional public switched telephone network circuits. Unlike its predecessor, which primarily transmitted voice, ISDN’s innovation lies in integrating speech and data on the same lines, a capability absent in traditional telephone systems. Operating as a circuit-switched ...
