HTTPS (HyperText Transfer Protocol Secure) is a protocol used for secure communication over a computer network, most commonly the internet. It encrypts data transmitted between a web browser and a web server, ensuring that sensitive information such as login credentials, payment details, and personal data remains private and protected from eavesdropping and tampering. HTTPS is … Read more

The primary purpose of a router is to forward data packets between computer networks. Routers operate at the network layer (Layer 3) of the OSI model and use IP addresses to determine the best path for data transmission across interconnected networks. They enable communication between devices in different LANs (local area networks) or WANs (wide … Read more

A router and modem are distinct networking devices with different functions: A modem is a device that modulates and demodulates analog signals to transmit digital data over communication channels such as telephone lines, cable systems, or fiber optic cables. Its primary function is to establish and maintain a connection to an Internet Service Provider (ISP), … Read more

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
