Learn about Personal Area Network (PAN)

Ngày đăng: 25/09/2020

A computer network is a collection of interconnected computers / devices, in which a connection is established for the purpose of communication between computers / devices, to share resources, data and applications. . There are different types of computer networks that are designed to operate in the area they cover and according to the network requirements, type of service, and coverage in which they are classified. What is a Personal Area Network (PAN) network? A Personal Area Network (PAN) is a network that connects computers / devices within an individual's range. Since PAN provides network coverage within a radius of around a person, typically around 10 meters (33 feet), it is called a Personal Area Network. The Personal Area Network typically includes computers, phones, tablets, printers, PDAs (Personal Digital Assistant) and other entertainment devices such as speakers, game consoles, etc.

What is SSTP (Secure Socket Tunneling Protocol)?

Ngày đăng: 25/09/2020

SSTP, or Secure Socket Tunneling Protocol, is designed to protect PPP traffic using an SSL / TLS channel. SSTP is better and much more secure for Windows users than L2TP / IPSec or PPTP . SSTP is difficult to block and only provides good speeds if you have enough bandwidth. What is SSTP (Secure Socket Tunneling Protocol)? Short for Secure Socket Tunneling Protocol, SSTP is a type of VPN tunnel that uses SSL 3.0 channel to send PPP or L2TP traffic. SSL allows for the transmission and encryption of data, as well as checks the integrity of the traffic.

Protocol difference between TCP and UDP

Ngày đăng: 25/09/2020

You may have seen TCP and UDP when setting up port forwarding on your router or when configuring your firewall software . These two protocols are used for different data types. TCP / IP is a set of ports used by equipment to communicate over the Internet and most local networks. It is named after its two original protocols - Transmission Control Protocol (TCP) and Internet Protocol (IP). TCP provides applications a way to deliver (and receive) a stream of ordered packets and check for errors over the network. The User Datagram Protocol (UDP) is used by applications to transport a data stream faster by bypassing error checking. When configuring network hardware or software you will see the difference.
