As a terminal emulator, the application provides text-based access to the operating system, in contrast to the mostly graphical nature of the user experience of macOS, by providing a command-line interface to the operating system when used in conjunction with a Unix shell, such as zsh (the default interactive shell since macOS Catalina [3]).

Docker is a set of platform as a service (PaaS) products that use OS-level virtualization to deliver software in packages called containers. [5] The service has both free and premium tiers. The software that hosts the containers is called Docker Engine. [6] It was first released in 2013 and is developed by Docker, Inc. [7]
TUN and TAP in the network stack. Though both are for tunneling purposes, TUN and TAP cannot be used together because they transmit and receive packets at different layers of the network stack. TUN, namely network TUNnel, simulates a network layer device and operates in layer 3 carrying IP packets.
A host is a node that participates in user applications, either as a server, client, or both. A server is a type of host that offers resources to the other hosts. Typically a server accepts connections from clients who request a service function. [4] Every network host is a node, but not every network node is a host.
This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for bidirectional traffic.
In non-promiscuous mode, when a NIC receives a frame, it drops it unless the frame is addressed to that NIC's MAC address or is a broadcast or multicast addressed frame. In promiscuous mode, however, the NIC allows all frames through, thus allowing the computer to read frames intended for other machines or network devices.
Remote Install Mac OS X was a remote installer for use with MacBook Air laptops over the network. It could run on a Mac or a Windows PC with an optical drive. A client MacBook Air (lacking an optical drive) could then wirelessly connect to the other Mac or PC to perform system software installs.
In computer networking, a host model is an option of designing the TCP/IP stack of a networking operating system like Microsoft Windows or Linux. When a unicast packet arrives at a host , IP must determine whether the packet is locally destined (its destination matches an address that is assigned to an interface of the host).
