SMTP (Simple Mail Transfer Protocol) is used for sending emails from a client to a server or between servers. POP3 (Post Office Protocol version 3) is used for retrieving emails from a server to a client. SMTP handles outgoing mail, while POP3 handles incoming mail. SMTP and POP3 differ in their primary functions and use … Read more
An access point (AP) is defined as a networking device that allows wireless devices, such as laptops, smartphones, and tablets, to connect to a wired network using Wi-Fi or other wireless standards. It acts as a bridge between wireless devices and the wired network infrastructure, providing wireless connectivity within its coverage area. In networking terminologies, … Read more
SSL (Secure Sockets Layer) is a security protocol that establishes an encrypted link between a web server and a browser. HTTPS (HyperText Transfer Protocol Secure) is an extension of HTTP that uses SSL or its successor TLS (Transport Layer Security) to encrypt data transmitted between the web server and the browser, ensuring secure communication. HTTPS … Read more
A DMZ port on a router or firewall is used to connect a device or a network segment that requires exposure to the public internet while still maintaining some security controls. It allows external access to specific services without exposing the internal network. The purpose of a DMZ (Demilitarized Zone) is to add an extra … Read more
What is IP Called? IP stands for Internet Protocol, a fundamental communication protocol in the TCP/IP suite used for relaying packets of data across network boundaries. It is primarily responsible for addressing, routing, and delivering packets from the source host to the destination host based on their IP addresses. IP is a network layer protocol, … Read more
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
NAT (Network Address Translation) and routing are both essential functions in networking that determine how data travels between networks, especially between local networks (LANs) and the internet. While they can operate together, they serve different purposes. Routing is responsible for directing traffic based on IP addresses, while NAT modifies IP address information in packet headers … 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
