A NAT (Network Address Translation) works by modifying the IP address information in the headers of IP packets as they pass through a router or firewall. This process allows multiple devices on a private network to share a single public IP address for accessing external networks, such as the internet. When an internal device sends … Read more
A VPN (Virtual Private Network) is a service that creates a secure, encrypted connection over a less secure network, such as the internet. It allows users to send and receive data as if their devices were directly connected to a private network. VPNs are used to enhance privacy and security by hiding the user’s IP … Read more
TCP (Transmission Control Protocol) works in conjunction with IP (Internet Protocol) to facilitate communication between devices over a network. TCP relies on IP addresses to identify endpoints in a network. When TCP initiates a connection or sends data, it specifies the IP address of the destination device. Each device in a TCP/IP network has a … Read more
DHCP (Dynamic Host Configuration Protocol) is a network management protocol used on IP networks to automatically assign IP addresses and other network configuration information to devices. It simplifies the process of IP address allocation by centralizing the management of IP addresses within a network. DHCP is typically used in local area networks (LANs) where a … Read more
A repeater works by amplifying or regenerating signals to extend the reach of a network or communication system. In telecommunications and networking, a repeater receives signals from one segment of a network, amplifies them, and retransmits them to another segment. This process helps to overcome signal degradation that occurs over long distances or due to … Read more
In the card game of bridge, several rules and guidelines shape how players strategize and bid during the game: Rule of Bridge: The fundamental rule of bridge is to win tricks, which involves playing cards strategically to outmaneuver opponents. Players bid on the number of tricks they believe they can win based on their card … Read more
DNS (Domain Name System) rules refer to the guidelines and configurations that govern the operation and management of DNS within a network or organization. These rules include setting up DNS servers, configuring zones and records, defining DNS resolution behavior, and ensuring security and reliability of DNS services. DNS rules also encompass policies for DNS name … Read more
The five basic commands of SNMP (Simple Network Management Protocol) are used for managing and monitoring network devices and systems. These commands include: GET: Retrieves the value of a specified object or variable from an SNMP agent running on a network device. It is used to query the current status or configuration of a device. … Read more
Near field techniques, including NFC (Near Field Communication), offer several advantages in various applications due to their specific characteristics: Short Range: One advantage is the short communication range (typically within a few centimeters), which enhances security by minimizing the risk of eavesdropping or unauthorized access. This makes NFC suitable for secure transactions, access control, and … Read more
The Address Resolution Protocol (ARP) serves the purpose of resolving IP addresses to MAC addresses within a local network segment. When a device wants to communicate with another device on the same network, it typically knows the IP address of the destination but needs to determine the corresponding MAC address (hardware address) to send data … Read more
