Many protocols use an XOR-based longitudinal redundancy check byte (often called block check character or BCC), including the serial line interface protocol (SLIP, not to be confused with the later and well-known Serial Line Internet Protocol), [8] the IEC 62056-21 standard for electrical-meter reading, smart cards as defined in ISO/IEC 7816, and the ACCESS.bus protocol.
Example of a ticket and "Now Serving" sign used in the Ticket Queue Management System. The basic concept of a ticket lock is similar to the ticket queue management system. This is the method that many bakeries and delis use to serve customers in the order that they arrive, without making them stand in a line.
Computer booking systems allow public service with reduced staff involvement. Typically a computer booking system consists of both server and client software. The server software might run within the LAN or more typically is run from a publicly accessible web-server thus enabling users to book or reserve their computer time from their web-browser.
The MARS-1 train ticket reservation system was designed and planned in the 1950s by the Japanese National Railways' R&D Institute, now the Railway Technical Research Institute, with the system eventually being produced by Hitachi in 1958. [6] It was the world's first seat reservation system for trains. [7]
It allows a passenger anywhere to book train tickets from any station to any station. PRS handles reservations, changes, cancellations and refunds, reserving over 1.6 million seats and berths daily. Complex rules, validations and fare-computation techniques are interwoven in the application. This system is currently under modernisation. [6]
An on-line monitoring system of a quality based routing is publicly available for a demo traffic. [3] Post-dial delay [4] is the time from dialing the last digit to the time a caller hears ringing. Another, more sophisticated way of measuring the call quality is Perceptual Evaluation of Speech Quality (PESQ). Such measurements are rarely used ...
Binary-code compatibility (binary compatible or object-code compatible) is a property of a computer system, meaning that it can run the same executable code, typically machine code for a general-purpose computer central processing unit (CPU), that another computer system can run.
The first computerized booking system was the little-known Trans-Canada Air Lines (today's Air Canada) system, ReserVec developed by Ferranti Canada. It started to be delivered in April 1961 and by January 24, 1963 completed the airline switch-over from the manual systems.
