The Unix command clear takes no arguments and is roughly analogous to the command cls on a number of other operating systems. In ISO 9995-7 specifies that the following symbol be used to indicate this function on a keyboard, which is included in Unicode as: ⎚ CLEAR SCREEN SYMBOL. [2] One may use the reset command to erase every previous command.
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 ...
The command is available in MS-DOS versions 2 (1983) and later. [5] While the ultimate origins of using the three-character string CLS as the command to clear the screen likely predate Microsoft's use, this command was present before its MS-DOS usage, in the embedded ROM BASIC dialects Microsoft wrote for early 8-bit microcomputers (such as TRS-80 Color BASIC), where it served the same purpose.
SSH is typically used to log into a remote computer's shell or command-line interface (CLI) and to execute commands on a remote server. It also supports mechanisms for tunneling, forwarding of TCP ports and X11 connections and it can be used to transfer files using the associated SSH File Transfer Protocol (SFTP) or Secure Copy Protocol (SCP).

In computer networking, localhost is a hostname that refers to the current computer used to access it. The name localhost is reserved for loopback purposes. [1] It is used to access the network services that are running on the host via the loopback network interface. Using the loopback interface bypasses any local network interface hardware.
A Terminal Operating System, or TOS, is a key part of a supply chain and primarily aims to control the movement and storage of various types of cargo in and around a port or marine terminal. The systems also enables better use of assets, labour and equipment, plan workload, and receive up-to-date information.
The name localhost is a commonly defined hostname for the loopback interface in most TCP/IP systems, resolving to the IP addresses 127.0.0.1 in IPv4 and ::1 for IPv6. As a top-level domain, the name has traditionally been defined statically in host DNS implementations with address records (A and AAAA) pointing to the same loopback addresses.
The A-terminal building The former B-terminal building which now is part of A-terminal. Shipping companies Eckerö Line and Viking Line operate scheduled services from A-terminal to Helsinki. [5] [6] [7] The A-terminal and the old B-terminal are connected to each other to provide more efficient passenger flow. [8] Terminal is served by bus line ...
