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 ...
It’s a common belief that anything that can be found online and is simple to access with a web browser counts as a website. However, this assumption doesn’t hold true if we observe closely. You encounter two main entities online: websites and web applications. These two serve different purposes, engaging users in varying degrees, and ...
Main difference between connection-oriented and connectionless is that connection-oriented service establishes a connection before data transmission whereas there is no connection establishment in connectionless service. TCP is a connection oriented and connectionless protocol is UPD. In this article, we will look at the difference between connection-oriented and connectionless services in detail. Connection-Oriented Services Every packet ...
At the heart of modern connectedness, a computer network is a web of interconnected devices communicating and exchanging resources in real time. It is a virtual highway connecting computers, smartphones, and other devices to enable collaboration, information exchange, and access to shared data. Consider it a digital neighborhood where information flows like a conversation, whether ...
PAN (Personal Area Network) is a close-knit network that allows your devices to communicate. Consider it your digital campfire, where devices like smartphones, computers, and wearables congregate for smooth data exchange. PANs utilize Bluetooth or Wi-Fi to provide a convenient, immediate link for sharing files, information, or even music without the hassle of a large ...
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 ...
OSI (Open System Interconnection) model is a conceptual model that is used to describe seven layers that computer systems use to communicate over a network. This model has been described in the form of 7 layers namely, Physical layer, Network layer, Data Link layer, transport layer, session layer, presentation layer and the application layer. All these 7 layers work together to transmit the ...
Data Link Layer is responsible for reliable point-to-point data transfer over a physical medium. To implement this data link layer provides three functions : What is Flow Control in the Data Link Layer? Flow control is a set of procedures that restrict the amount of data a sender should send before it waits for some acknowledgment from the ...
Cryptography is a term used in data communication that refers to protecting the private information shared between two parties. Network Security refers to securing and protecting the network and data to ensure the confidentiality of data. What is Cryptography? Cryptography generally deals with the study and practice of techniques for ensuring secure communication between two parties ...
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 ...
