The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. [3] They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the ...
Port numbers are categorized into three basic categories: well-known, registered, and dynamic or private. The well-known ports are assigned by the Internet Assigned Numbers Authority (IANA) and are typically used by system-level processes. Well-known applications running as servers and passively listening for connections typically use these ports.
In computer networking, a port or port number is a number assigned to uniquely identify a connection endpoint and to direct data to a specific service. At the software level, within an operating system, a port is a logical construct that identifies a specific process or a type of network service.
However, programs running inside a container can only see the container's contents and devices assigned to the container. This provides many of the benefits that virtual machines have such as standardization and scalability, while using less resources as the kernel is shared between containers.

In computer networking, port forwarding or port mapping is an application of network address translation (NAT) that redirects a communication request from one address and port number combination to another while the packets are traversing a network gateway, such as a router or firewall.
During a Communist Party meeting earlier this month, Cuban leader Miguel Díaz-Canel blamed U.S. sanctions -- the government’s favorite whipping boy -- for the crisis.
A container format (informally, sometimes called a wrapper) or metafile is a file format that allows multiple data streams to be embedded into a single file, usually along with metadata for identifying and further detailing those streams. [1]
The X server acts as a go-between for the user and the client programs, accepting requests on TCP port 6000 plus the display number [1] for graphical output (windows) from the client programs and displaying them to the user (display), and receiving user input (keyboard, mouse) and transmitting it to the client programs.
