DNS (Domain Name System) translates human-readable domain names into IP addresses that computers use to identify each other on the network. NAT (Network Address Translation) modifies network address information in IP packet headers while in transit, enabling multiple devices on a local network to share a single public IP address. NAT (Network Address Translation) translates … Read more
TCP (Transmission Control Protocol) is known for its reliability in data transmission. It ensures that data sent over a network arrives at its destination intact and in the correct order. TCP achieves this through mechanisms such as error detection, retransmission of lost packets, and flow control to manage data transmission rates effectively. TCP is best … Read more
A VPN (Virtual Private Network) is a service that creates a secure and encrypted connection over a less secure network, such as the internet. It is used to protect data privacy, ensure secure remote access to a network, and conceal the user’s IP address and online activities. The main purpose of a VPN is to … Read more
In the OSI model, a repeater operates at Layer 1, also known as the physical layer. Its primary function is to regenerate and amplify signals as they travel across a network medium, such as a copper wire or fiber optic cable. By boosting the signal, a repeater extends the distance over which data can reliably … Read more
DNS (Domain Name System) translates human-readable domain names into IP addresses, allowing users to access websites using easy-to-remember names instead of numerical IP addresses. DHCP (Dynamic Host Configuration Protocol) automatically assigns IP addresses and other network configuration parameters to devices on a network, enabling them to communicate efficiently. DNS (Domain Name System) converts domain names … Read more
A repeater is a networking device used to regenerate and amplify signals as they travel across a network medium, typically at the physical layer (Layer 1) of the OSI model. It is commonly used in scenarios where the transmission distance of signals needs to be extended without signal degradation. Repeaters are especially useful in Ethernet … Read more
A bridge in networking is a device that connects multiple network segments or LANs (Local Area Networks) together at the data link layer (Layer 2) of the OSI model. It operates by examining the MAC addresses of incoming data packets and selectively forwarding them to the appropriate segment based on their destination MAC address. Bridges … Read more
A software-defined system refers to an infrastructure where the functionality and behavior of hardware resources are controlled and managed through software, rather than being defined by the hardware itself. This approach allows for greater flexibility, scalability, and automation in managing and provisioning resources across networks, data centers, and other IT environments. SDN, or Software-Defined Networking, … Read more
Software-Defined Wide Area Networking (SD-WAN) refers to a technology that simplifies the management and operation of a wide area network (WAN) by separating the networking hardware from its control mechanism. It enables centralized management and configuration of WAN connections, allowing organizations to dynamically route traffic across multiple locations, optimize application performance, and improve network agility … Read more
Content delivery in networking refers to the process of distributing and delivering digital content, such as web pages, images, videos, and other media, from a source to end-users over the internet. It involves optimizing the delivery process to ensure fast, reliable, and efficient transmission of content to users regardless of their geographical location or network … Read more
