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
SNMP tools are software applications or utilities used to manage, monitor, and configure network devices using the Simple Network Management Protocol (SNMP). These tools can collect data on network performance, detect faults, and provide insights into network health. SNMP devices are network devices, such as routers, switches, servers, printers, and other hardware, that support and … Read more
A bridge in networking is defined as a device that connects two or more separate networks or network segments, allowing them to communicate with each other. It operates at the data link layer (Layer 2) of the OSI model, where it forwards data packets based on the MAC (Media Access Control) addresses contained within them. … Read more
IMAP (Internet Message Access Protocol) is used for retrieving and managing email messages from a mail server. It allows users to access their email from multiple devices, as messages are stored on the server and synchronized across all devices. IMAP protocol is used by individuals and organizations who need to access their email from various … Read more
There are two primary types of access points (APs) used in networking: Wired Access Points: These APs are connected to the network via Ethernet cables and provide wireless connectivity to devices within their coverage area. They typically integrate with existing wired networks to extend network access wirelessly. Wireless Access Points: These APs operate wirelessly and … Read more
