Binary code practical applications such as computers, electric circuits, and more. The bit string is not the only type of binary code. A binary system, in general, is any system that allows only two choices such as a switch in an electronic system or a simple true or false test. Braille is a type of binary code that is widely used by the blind to read and write by touch, named for its creator, Louis Braille. This system consists of grids of six dots each, three per column, in which each dot has two states: raised or not raised. The different combinations
Read-copy-update "RCU" was one of many contributions by the Linux community. Other names for similar techniques include "passive serialization" and "MP defer" by VM/XA programmers and "generations" by K42 and Tornado programmers. Techniques and mechanisms resembling RCU have been independently invented multiple times: Bauer, R.T., (June 2009), "Operational Verification of a Relativistic Program" PSU Tech Report TR-09-04 (http://www.pdx.edu/sites/www.pdx.edu.computer-science/files/tr0904.pdf) Read-copy-update In computer science, read-copy-update (RCU) is a synchronization mechanism based on mutual exclusion. It is used when performance of reads is crucial and is an example of space–time tradeoff, enabling fast operations at the cost of more space. Read-copy-update allows multiple threads
