High-availability Seamless Redundancy High-availability Seamless Redundancy ( HSR) is a network protocol for Ethernet that provides seamless failover against failure of any single network component. PRP and HSR are independent of the application-protocol and can be used by most Industrial Ethernet protocols in the IEC 61784 suite. HSR does not cover the failure of end nodes, but redundant ...
Code page In computing, a code page is a character encoding and as such it is a specific association of a set of printable characters and control characters with unique numbers. Typically each number represents the binary value in a single byte. (In some contexts these terms are used more precisely; see Character encoding § Terminology .)
Parallel Redundancy Protocol ( PRP) is a network protocol standard for Ethernet that provides seamless failover against failure of any network component. This redundancy is invisible to the application.
Hardware code page. In computing, a hardware code page ( HWCP) refers to a code page supported natively by a hardware device such as a display adapter or printer. The glyphs to present the characters are stored in the alphanumeric character generator 's resident read-only memory (like ROM or flash) and are thus not user-changeable.
The line printer employed a series of status codes, specifically ready, online, and check. If the online status was set to "off" and the check status was set to "on," the operating system would interpret this as the printer running out of paper.
The Hart–Scott–Rodino Antitrust Improvements Act of 1976 (Public Law 94-435, known commonly as the HSR Act) is a set of amendments to the antitrust laws of the United States, principally the Clayton Antitrust Act. The HSR Act was signed into law by president Gerald R. Ford on September 30, 1976. The context in which the HSR Act is usually cited is 15 U.S.C. § 18a, title II of the original ...
Printer Job Language ( PJL) is a method developed by Hewlett-Packard for switching printer languages at the job level, and for status readback between the printer and the host computer.
Code page 437 ( CCSID 437) is the character set of the original IBM PC (personal computer). [2] It is also known as CP437, OEM-US, OEM 437, [3] PC-8, [4] or DOS Latin US. [5] The set includes all printable ASCII characters as well as some accented letters ( diacritics ), Greek letters, icons, and line-drawing symbols.
