TCP operates with the internet protocol (IP) to specify how data is exchanged online. IP is responsible for sending each packet to its destination, while TCP guarantees that bytes are transmitted in the order in which they were sent with no errors or omissions. Together, the two protocols are...

其实说HTTP协议可靠协议并不是特别的准确,HTTP的可靠性一部分来自于HTTP协议自身,一部分来自于它所依赖的上层TCP协议。 TCP本身就是一个可靠的传输协议,它的可靠性其实就是来自于三次握手,通过客户端与服务器的沟通来确定是否建立连接,UDP就没这么麻烦,传过去就完事了,我管你收没收到。所以基于这样的因素,TCP就不...
Port numbers. Each port is assigned a unique number, ranging from 0 to 65535, which identifies the type of service or application. For example, HTTP typically uses port 80, while HTTPS uses port 443. TCP and UDP protocols.Ports operate using either the transmission control protocol (TCP) or...
This article explores what is an open port and closed port? Risks of open ports, port scanning and how to monitor. Learn more on attack surface reduction.
The Internet protocol suite is a set of protocols used on the Internet and commonly referred to as TCP/IP. IP is a core protocol in this suite and operates at the Internet layer. IP defines an addressing scheme, in which IP addresses are used to identify segments, device interfaces, and ...
This information is not protected by HTTPS because it pertains to the network or transport layer rather than the application layer where HTTPS operates. Hence to establish an HTTPS connection, a TCP 443, i.e., a TCP request, is sent via port 443 to establish the connection. ...
The LSR with the larger transport address serves as the active peer and initiates a TCP connection request. In this example, LSR A functions as the active peer, while LSR B is the passive peer. After the TCP connection is successfully established, LSR A sends an Initialization message to ...
TCP/IP Stands for "Transmission Control Protocol over Internet Protocol." TCP/IP is the standard suite ofprotocolsused by computers and other devices to communicate over networks. This protocol suite serves as the basic foundation of theInternet. As the abbreviation implies, the TCP/IP suite ...
SSL operates directly on top of transmission control protocol (TCP), allowing higher protocol layers to remain unchanged while providing a secure connection. If an SSL certificate is configured correctly, attackers can only see the domain and port you are connected to and how much data is being ...
