A switch in computer networking is a device that operates at the data link layer (Layer 2) of the OSI model and is used to connect multiple devices within a local area network (LAN). Unlike hubs, switches intelligently forward data packets only to the specific devices that need to receive them, based on their MAC … Read more
WWW (World Wide Web) refers to the collection of websites and web pages accessible over the internet using web browsers. It encompasses the entire network of interconnected hypertext documents and multimedia content that users can access through URLs (Uniform Resource Locators). HTTPS (HyperText Transfer Protocol Secure) is a protocol for secure communication over a computer … Read more
A switch and a router are both essential networking devices, but they serve different roles within a network. A switch operates at Layer 2 (Data Link Layer) of the OSI model and primarily handles communication within a local area network (LAN). A router operates at Layer 3 (Network Layer) and is responsible for routing data … Read more
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
POP3 (Post Office Protocol version 3) and IMAP (Internet Message Access Protocol) are both protocols used for retrieving email from a mail server. POP3 downloads email messages to the local device and often removes them from the server, while IMAP synchronizes email messages across multiple devices, keeping them on the server. IMAP is generally considered … Read more
FTP (File Transfer Protocol) is a standard network protocol used for transferring files between a client and a server on a computer network. It provides a straightforward method for uploading and downloading files, making it commonly used for file sharing and website maintenance. SMTP (Simple Mail Transfer Protocol) is a protocol used for sending email … Read more
The function of a modem, short for modulator-demodulator, is to modulate and demodulate digital data signals so they can be transmitted over analog communication channels. In practical terms, modems convert digital data from computers or other digital devices into analog signals suitable for transmission over telephone lines, cable systems, or fiber optics. Conversely, they also … Read more
SMTP (Simple Mail Transfer Protocol) is used for sending email messages from a sender’s email client or server to the recipient’s email server. It ensures that emails are routed and delivered reliably across different networks, facilitating communication via email over the internet. The purpose of SMTP is to handle the transmission of email messages between … Read more
