Ethernet refers to a networking technology used for local area networks (LANs) to connect devices within a confined area such as an office building, school campus, or home. It defines how data is transmitted over physical cables or wireless connections, specifying protocols for data encoding, framing, collision detection, and media access control. Ethernet and the … Read more
The TCP/IP model consists of four layers, each playing a crucial role in the transmission of data across networks: Application Layer: The topmost layer in the TCP/IP model, the Application Layer, interacts directly with end-user applications. It provides network services directly to user applications, enabling tasks such as file transfer, email communication (SMTP, POP3), web … Read more
A DHCP IP address refers to an IP address assigned dynamically to a device by a DHCP (Dynamic Host Configuration Protocol) server within a network. DHCP simplifies the process of IP address management by automatically assigning IP addresses to devices when they connect to the network, eliminating the need for manual configuration. DHCP IP addresses … Read more
HTTP stands for Hypertext Transfer Protocol. It is a protocol used for transmitting hypertext messages, such as HTML files, over the internet. HTTP defines how messages are formatted and transmitted between clients (such as web browsers) and servers (where websites are hosted). It operates on top of the TCP/IP protocol suite and uses standardized methods, … Read more
The main reasons to use the cloud encompass several key benefits that organizations and individuals find compelling.

WML, or Wireless Markup Language, serves the function of providing a markup language specifically designed for wireless devices. It was initially developed as part of the WAP (Wireless Application Protocol) suite to enable the creation of web content that could be displayed on mobile phones and other wireless devices with limited display capabilities and bandwidth. … Read more
An access point is a device that allows wireless devices to connect to a wired network using Wi-Fi. It acts as a central transmitter and receiver of wireless radio signals, enabling devices such as laptops, smartphones, and tablets to join a network without requiring physical cables. Access points are primarily used to extend the reach … Read more
A device hub, in general terms, refers to a central point or device that allows multiple devices to connect and communicate with each other within a network. It serves as a junction where devices can share data and information, facilitating communication among them. A hub device, in networking, refers to a hardware device that acts … Read more
The purpose of a reverse proxy is to act as an intermediary server between clients (such as web browsers) and backend servers (such as web servers or application servers). Unlike a forward proxy, which handles requests from clients to access resources on the internet, a reverse proxy manages incoming requests from clients seeking resources hosted … Read more
Switching in a computer network refers to the process of forwarding data packets between devices within a local area network (LAN). It involves a network switch, which is a hardware device that operates at the data link layer (Layer 2) or network layer (Layer 3) of the OSI model. Switches use MAC addresses or IP … Read more
