What’s Bisync?

Bisync is a binary synchronous communication used on mainframe computers for efficient data exchange. It requires binary data and synchronized connections between computers for a steady flow of data. Bisync can occur multiple times with no substantial downtime between transmissions.

Bisync is an abbreviation for binary synchronous communication. This type of communication is typically used on mainframe computers, which are large-scale networks capable of supporting hundreds or even thousands of users at a time. Through a bisync operation, binary data can be passed directly from computer to computer through a synchronized connection on this system. A synchronized connection is a connection that transmits data at regular intervals. This allows files and other important data to be exchanged across the computer network in a timely and efficient manner.

The requirements for a bisync operation are twofold. First, data transmitted from computer to computer must be in binary form. Binary is the most basic of all computer languages, where everything is expressed as strings of the characters “1” and “0”. “1” indicates an “On” circuit and “0” indicates an “Off” circuit; through combinations of these characters, any letter, number or data can be effectively transferred. Each “1” or “0” takes up a single bit of storage space on your computer.

Synchronization is the second requirement of a bisync transfer. It means that computers exchanging information must first be synchronized together for the data exchange to take place. The concept of being synchronized means that computers exchange data in a regular pattern at regular intervals; provides a constant flow of data from one computer to another. This differs from most types of computer communication, which is asynchronous, meaning that information arrives erratically until the transfer is complete.

When both requirements are met, a bisync transfer of data can occur. Like pouring a bucket of water down a chute, data transferred from one computer to another flows in a steady stream until the communication ends. At that point, the synchronous connection between the computers closes, breaking the bisync communication. Although the connection terminates when the transmission closes, there is no real limit to the number of bisync operations that can occur over time. In theory, a pair of computers could perform back-to-back desynchronized communications with no substantial downtime between transmissions.
