ASCII The Evolution of Character Codes Book download PDF

June 15, 2020



Today we take it for granted that a ‘‘plain text’’ file on a computer can be read by nearly any program, printed on any printer, displayed on any screen, transmitted over any network, and understood equally easily by any other make or model of computer. Plain text is plain, though, only because of a near-universal agreement about what symbols and actions correspond to what arbitrary arrangement of bits, an agreement that was reached only after many years of design work, experimentation, and compromise.


The first portion of the paper will cover the origins of International Telegraph Alphabet No. 2 (often called ‘‘Baudot’’), the five-unit code standardized in the 1930s. The second portion will cover the design and standardization of its successor, the seven-bit international standard code now used by the majority of the world’s computers and networks.

Version control is the management of the changes made within a system, that it has not to be software necessarily. Even if you have never used before Git or similar tools, you will probably have ever carried out a version control. A very used and bad practice in software developing is, when the software has reached a stable situation, saving a local copy of it, identifying it as stable, and then following with the changes in other copy.

This is something that every software engineer has done before using specific tools version controlling, so don’t feel bad if you have done it.

Everyone uses electronic devices, but most of us don’t really know what goes on inside them. Of course, you may feel that you don’t need to know. If you can drive a car without understanding the workings of an internal combustion engine, presumably you can use an iPod without knowing anything about integrated circuits. However, understanding some basics about electricity and electronics can be worthwhile for three reasons:

  • By learning how technology works, you become better able to control your world instead of being controlled by it. When you run into problems, you can solve them instead of feeling frustrated by them. 
  • Learning about electronics can be fun—so long as you approach the process in the right way. The tools are relatively cheap, you can do all the work on a tabletop, and it doesn’t consume a lot of time (unless you want it to). 
  • Knowledge of electronics can enhance your value as an employee or perhaps even lead to a whole new career.
