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
Wi-Fi Protected Access 2 (WPA2) is a security protocol designed to secure wireless computer networks. It is an improvement over its predecessor, WPA, and provides stronger encryption and security mechanisms to protect Wi-Fi networks from unauthorized access and attacks. WPA2 operates using the IEEE 802.11i standard and utilizes the Advanced Encryption Standard (AES) encryption algorithm, … Read more
SSH (Secure Shell) offers several benefits that make it a widely used protocol for secure remote access, file transfer, and management of networked devices: The benefits of SSH include: Security: SSH provides strong encryption of data during transmission, preventing unauthorized access and eavesdropping. It uses cryptographic techniques to authenticate parties and ensure data integrity, offering … 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
