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

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
