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
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
Near Field Communication (NFC) serves the purpose of enabling wireless communication between devices in close proximity (typically within a few centimeters). The primary goal of NFC is to facilitate convenient and secure interactions between devices, allowing them to exchange data, initiate actions, or conduct transactions by simply bringing them close together or near an NFC … Read more
ICMP (Internet Control Message Protocol) does not use ports in the traditional sense like TCP and UDP protocols. Instead, it operates at a lower level in the network stack, primarily for diagnostic purposes and error reporting within IP networks. ICMP messages are encapsulated within IP packets and do not have a port number field in … Read more
DHCP (Dynamic Host Configuration Protocol) is a network management protocol used to automate the assignment of IP addresses, subnet masks, gateway addresses, and other IP configuration parameters to devices on a network. Its primary importance lies in simplifying network administration and management by eliminating the need for manual IP configuration on each device. DHCP dynamically … Read more
The purpose of using Spanning Tree Protocol (STP) in computer networks is to prevent and manage network loops that can occur in Ethernet environments. STP ensures network reliability and stability by dynamically identifying and blocking redundant paths between switches or bridges. By maintaining a loop-free topology, STP enables efficient data transmission and minimizes the risk … Read more
The need for SD-WAN (Software-Defined Wide Area Network) arises from the evolving demands of modern enterprise networks. Traditional WAN architectures often struggle to support the increasing volume of cloud applications, remote workforce needs, and diverse network traffic patterns. SD-WAN addresses these challenges by providing centralized management, automation, and dynamic traffic steering capabilities across geographically dispersed … Read more
Multiprotocol Label Switching (MPLS) is used primarily for efficiently forwarding data packets across a network based on labels rather than IP addresses. It combines the scalability of IP routing with the speed of Layer 2 switching, making it suitable for optimizing traffic flow in large networks, including service provider networks and enterprise environments. MPLS works … Read more
Factors of Quality of Service (QoS) encompass several key elements that collectively contribute to ensuring satisfactory performance and reliability of network services. These factors include: Bandwidth: The available capacity of the network link or interface, which determines how much data can be transmitted within a given period. Adequate bandwidth allocation is crucial for supporting QoS … Read more
