This article lists protocols, categorized by the nearest layer in the Open Systems Interconnection model.This list is not exclusive to only the OSI protocol family.Many of these protocols are originally based on the Internet Protocol Suite (TCP/IP) and other models and they often do not fit neatly into OSI layers.
General Comprehensive Operating System (GCOS, / ˈ dʒ iː k oʊ s /; originally GECOS, General Electric Comprehensive Operating Supervisor) [a] is a family of operating systems oriented toward the 36-bit GE-600 series [1] and Honeywell 6000 series [2] mainframe computers. The original version of GCOS was developed by General Electric beginning ...
An ISO 8583 message is made of the following parts: Message type indicator (MTI) One or more bitmaps, indicating which data elements are present. It consists of primary bitmap and secondary bitmap. The first bit of the primary bitmap indicates whether the secondary bitmap is present or not. Data elements, the actual information fields of the ...
Contains 8 1-bit flags (control bits) as follows: CWR: 1 bit Congestion window reduced (CWR) flag is set by the sending host to indicate that it received a TCP segment with the ECE flag set and had responded in congestion control mechanism. [22] [a] ECE: 1 bit ECN-Echo has a dual role, depending on the value of the SYN flag. It indicates:
A 32-bit PC BIOS will search for boot code on an ISO 9660 CD-ROM. The standard allows for booting in two different modes. Either in hard disk emulation when the boot information can be accessed directly from the CD media, or in floppy emulation mode where the boot information is stored in an image file of a floppy disk , which is loaded from ...
The following protocols were designed for serial communication, mostly for the RS-232 standard. They are used for uploading and downloading computer files via modem or serial cable (e.g., by null modem or direct cable connection). UUCP is one protocol that can operate with either RS-232 or the Transmission Control Protocol as its transport.
