HTTP Protocol HTTP stands for Hypertext Transfer Protocol. It is a protocol used for transmitting hypermedia documents, such as HTML files, over the internet. HTTP defines how messages are formatted and transmitted between web servers and web browsers, allowing users to access and interact with web pages, images, videos, and other content on the World …
Simple Network Management Protocol (SNMP)wha SNMP stands for Simple Network Management Protocol. It is an application-layer protocol used to manage and monitor network devices and systems in a network management system (NMS). SNMP allows network administrators to collect information about network devices, monitor network performance, and manage network configurations remotely. SNMP operates over UDP (User …
SMTP Protocol SMTP stands for Simple Mail Transfer Protocol. It is a standard communication protocol used for sending and relaying email messages between email servers on the internet. SMTP governs the transmission of emails from the sender’s email client or server to the recipient’s email server. SMTP is part of the TCP/IP protocol suite and …
File Transfer Protocol (FTP) File Transfer Protocol (FTP) is a standard network protocol used for transferring files between a client and a server over a TCP/IP based network, such as the internet. It allows users to upload, download, and manage files stored on remote servers, making it an essential tool for file sharing and remote …
DNS Protocol DNS stands for Domain Name System. It is a hierarchical decentralized naming system used to translate domain names (e.g., www.topperworld.in) into IP addresses (e.g., 192.0.2.1) and vice versa. DNS serves as the “phonebook” of the internet, enabling users to access websites and other internet services using human-readable domain names instead of numerical IP …
Network Security Network security refers to the practice of implementing measures to protect computer networks, devices, and data from unauthorized access, misuse, modification, or destruction. It encompasses a broad range of technologies, processes, and policies designed to safeguard the confidentiality, integrity, and availability of information transmitted and stored within a network. Network security aims to …
Digital Signature in Computer Networks A digital signature is a cryptographic technique used to verify the authenticity and integrity of digital messages or documents. It provides a way to ensure that the message has not been altered or tampered with during transmission and that it indeed originated from the expected sender.It involves using a pair …
Network security Protocols Network security protocols are a set of rules and procedures designed to secure communication and data exchange over computer networks. These protocols define standardized methods for implementing security mechanisms to protect against various cyber threats, including unauthorized access, data interception, tampering, and denial of service attacks. Network security protocols play a crucial …
Cryptography in Computer Network Cryptography is the science and practice of securing communication and data by converting plain text into unintelligible ciphertext and vice versa. It involves techniques for encrypting and decrypting information to ensure confidentiality, integrity, and authenticity in various communication channels and data storage systems. Cryptography plays a crucial role in protecting sensitive …
Routing Algorithms in Computer Networks Routing algorithms are a fundamental component of computer networks, responsible for determining the best path for data packets to travel from a source to a destination across a network. These algorithms enable efficient packet forwarding, help manage network congestion, and optimize overall network performance. Routing algorithms operate at the network …
