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
Network Address Translation (NAT) improves security primarily by acting as a barrier between the public internet and private networks. NAT modifies the source and/or destination IP addresses of packets as they traverse a router or firewall, masking the internal IP addresses of devices within the private network. This process hides the structure of the internal … Read more
The purpose of a Secure Shell (SSH) is to provide a secure method for accessing and managing remote systems over a network, typically the internet. SSH ensures confidentiality, integrity, and authenticity of data transmitted between a client (local computer or device) and a server (remote computer or device). It achieves this by encrypting all communication … Read more
An access point (AP) works by bridging wireless devices to a wired network infrastructure. It serves as a central hub for wireless communication, allowing devices such as laptops, smartphones, and tablets to connect to a network and access resources like the internet. The access point receives data from connected devices via wireless signals, forwards this … Read more
Port Address Translation (PAT) serves the purpose of allowing multiple devices within a private network to share a single public IP address. It extends the functionality of Network Address Translation (NAT) by not only translating IP addresses but also modifying port numbers within the TCP/UDP header of outgoing packets. By assigning unique port numbers to … Read more
The purpose of Remote Desktop Services (RDS) is to enable users to access and interact with remote desktops or applications hosted on servers over a network. Formerly known as Terminal Services, RDS allows multiple users to simultaneously connect to a centralized server environment and run applications or access desktop environments from their local devices. This … Read more
The purpose of SNTP (Simple Network Time Protocol) is to synchronize clocks of computers or network devices with a reliable time source over a network. SNTP is a simplified version of the Network Time Protocol (NTP) and is designed for systems that do not require the advanced features and precision of NTP. It provides basic … 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
