Stage 18. The branch of mathematics applied to computer science is particularly important for programming

This is essentially marked by a digital binary language consisting of 0 and of

Step 1.. Each sign is called a bit and measures an elementary amount of information. Eight bits form a byte (or a byte). Concerning the multiples of bytes, we commonly use the units of the international system, namely the kilo-, the mega- … However, unlike the other units of measurement, the multiples of the byte have been calculated in base 2 (and not in base 10), which means that a kilobyte was equal to 2 ^ 10 or 1,024 bytes. For reasons of uniformity, new prefixes were created in 1998. So don't be surprised to find a storage capacity expressed in kibibyte (kiB) or in mebibyte (MiB). To conclude on this small difficulty, we still often find the notation prior to 1998 when in reality, a kilobyte is worth 1000 bytes while a kibibyte is worth 1024 bytes

Step 19. Learn the different numbering systems (binary, octal, decimal, hexadecimal) and to switch from one to the other by conversion (from hexadecimal to binary, from decimal to octal.



  • When repairing a computer, keep external storage equipment close at hand (USB key, external hard drive, etc.) to transfer files if necessary. This can allow you to target a problem and / or protect your files.
  • Whatever operating system you are using (Windows, Mac OS, GNU / Linux…), install software to protect against viruses and malicious programs. Take care when downloading them, as they may contain programs from which they are supposed to protect you.
  • Take care that your computer does not overheat when you handle it, especially if you overclock (or overclock in English). Provide a cooling system if necessary.
  • Download at least five antivirus and protection software and a free operating system to a USB drive. Keep this key handy when repairing software.


  • Be aware that if you attempt to repair your computer yourself (including a hardware problem), you may void your warranty.
  • A geek is not someone who spends their time talking on forums or creating viruses. Far from this particularly negative cliché, a geek is a computer enthusiast eager for knowledge in the field. If your ambition is to expand, disseminate and share your computer science knowledge, you are a real geek!
