How does near field communication work?

Near Field Communication (NFC) works by enabling short-range wireless communication between NFC-enabled devices, typically within a range of a few centimeters. NFC operates on the principle of electromagnetic induction, where devices generate radio frequency fields that allow them to communicate and exchange data when brought into close proximity. This technology facilitates various applications such as … Read more

What is network address translation or NAT?

Network Address Translation (NAT) is a technique used in IP networking to translate private IP addresses used within a local network into public IP addresses that are routable over the internet. It allows multiple devices within a private network to share a single public IP address, conserving IP address space and providing a layer of … Read more

What is the SFTP protocol?

SFTP (Secure File Transfer Protocol) is a network protocol that provides secure file access, transfer, and management capabilities over SSH (Secure Shell) connections. Unlike FTP (File Transfer Protocol), which does not encrypt data by default, SFTP encrypts both commands and data transmitted between a client and server, ensuring confidentiality and data integrity during file transfers. … Read more

What is the use of a VPN?

A Virtual Private Network (VPN) serves several purposes and offers numerous benefits in today’s digital landscape. Primarily, a VPN is used to create a secure and private connection over a public network, typically the internet. It encrypts the data transmitted between the user’s device (such as a computer or smartphone) and a VPN server, ensuring … Read more

What is Wireless Fidelity known as?

Wireless Fidelity, commonly known as Wi-Fi, refers to a technology that enables wireless networking and internet access in various devices such as computers, smartphones, tablets, and IoT devices. Wi-Fi operates by using radio waves to transmit data between devices within a local area network (LAN), allowing users to connect to the internet or communicate with … Read more

What is VLAN used for?

A VLAN (Virtual Local Area Network) is used to logically segment a single physical network into multiple virtual networks. It allows network administrators to group devices logically, regardless of their physical location, into separate broadcast domains. This segmentation enhances network security, efficiency, and management by isolating traffic within specified VLANs and controlling communication between them. … Read more

What is transport layer security TLS used for?

Transport Layer Security (TLS) is a cryptographic protocol designed to provide secure communication over a computer network. It operates at the transport layer of the OSI model and ensures privacy, data integrity, and authentication between communicating applications. TLS is commonly used to secure data transmitted over the internet, such as web browsing, email communication, file … Read more

How does Wireless Fidelity work?

Wireless Fidelity, or Wi-Fi, works by using radio waves to transmit data between devices within a local area network (LAN). Wi-Fi operates on the IEEE 802.11 standards, which define the protocols and specifications for wireless networking. Devices such as computers, smartphones, tablets, and IoT devices connect to Wi-Fi networks by communicating with a wireless access … Read more

What is RDP and how does it work?

RDP, or Remote Desktop Protocol, is a proprietary protocol developed by Microsoft that enables users to remotely access and control computers running Windows operating systems. RDP works by transmitting graphical user interface (GUI) data, keyboard input, mouse movements, and other peripheral device interactions over a network connection between a client device and a remote desktop … Read more

What is a software defined wireless area network?

A software-defined wireless area network (SD-WAN) is a virtual WAN architecture that allows enterprises to leverage any combination of transport services, including MPLS, LTE, and broadband internet services, to securely connect users to applications. SD-WAN uses a centralized control function to direct traffic across the WAN in a secure and intelligent manner. This improves application … Read more
