Beschreibungen
The c't Know-how 2024 special issue offers in-depth knowledge on IT topics. It examines long-standing IT myths for their accuracy, such as whether changing passwords regularly actually enhances security.
The editorial team explains the workings of AI models and their potential beyond automated text and image generation.AI image generating tools sometimes deliver unexpected results and eavesdropping cars may enhance road safety in the future.
The special issue also provides answers to unexpected questions - such as how to decrypt a QR code, mathematical methods that may not have been taught by your math teacher, and how to crack an encryption that has challenged scientists for 300 years.
