RDP (Remote Desktop Protocol) works by enabling a user to remotely access and control a computer or server over a network. Here’s how RDP typically operates: Session Initialization: The RDP client initiates a connection request to the remote computer, typically using the computer’s IP address or hostname. Authentication: The user provides credentials (username and password) … Read more

ARP (Address Resolution Protocol) and DNS (Domain Name System) serve different purposes in networking, but both are essential for communication between devices on a network: ARP works at the data link layer (Layer 2) of the OSI model and is used to resolve IP addresses to MAC addresses within a local network. When a device … Read more

NFS, or Network File System, is a distributed file system protocol that allows a user on a client computer to access files over a network as if those files were located on the local filesystem. It enables seamless sharing of files and resources between multiple computers in a network. NFS operates on the client-server model, … Read more

NFS, or Network File System, operates on a client-server architecture where one or more NFS servers provide shared access to files and directories over a network. The server makes designated directories available for mounting by NFS clients. When a client mounts an NFS share, it establishes a connection to the server and can then access … Read more

TACACS (Terminal Access Controller Access-Control System) is an authentication method used to provide centralized access control for network devices such as routers, switches, and firewalls. It separates the authentication, authorization, and accounting (AAA) processes, allowing for granular control over who can access which resources. TACACS originally evolved into TACACS+ to address limitations in the original … Read more

IGMP, or Internet Group Management Protocol, is a communications protocol used by hosts and adjacent routers on IP networks to establish and manage multicast group memberships. It is used primarily in IPv4 networks and enables efficient delivery of data to multiple receivers without the need to send multiple copies of the same data. IGMP is … Read more

The purpose of an Ethernet is to provide a reliable and standardized method for connecting devices within a local area network (LAN). Ethernet technology facilitates the transmission of data packets between computers, printers, routers, and other networked devices using a wired connection. It supports high-speed data transfer rates, network reliability, and scalability, making it suitable … Read more

Bluetooth in Android devices operates by establishing a wireless connection between two devices using radio waves in the 2.4 GHz frequency band. It enables data exchange over short distances, typically up to 10 meters, without requiring a physical connection. Android devices use Bluetooth to connect and communicate with other Bluetooth-enabled devices such as headphones, speakers, … Read more

MPLS (Multiprotocol Label Switching) is a protocol used in telecommunications and computer networks to speed up and shape network traffic flows. Its primary function is to direct data packets along predetermined paths through the network. MPLS operates at Layer 2.5, between traditional Layer 2 (Data Link) and Layer 3 (Network) of the OSI model. This … Read more

The need for TLS (Transport Layer Security) arises from the necessity to secure data transmitted over the internet against unauthorized access and interception. TLS encrypts data exchanged between devices, such as web browsers and servers, ensuring confidentiality and integrity during transmission. It protects sensitive information, such as login credentials, financial details, and personal data, from … Read more
