Summary
- The basis for everything we do with computers is taking what we work with in the physical world, like images, text, numbers, symbols, and more, and abstract it into a format that computers can process, store, and transmit. Using binary bits, states of on or off, information can be encoded and decoded using standardized protocols. This allows information to be saved and retrieved or sent and received. But there are some limitations like working within bit sizes, preventing overflows, and conforming to encoding protocols like ASCII or Unicode. But with binary, it is possible to take anything we can represent in the real world and abstract it into a native format for computers. Understanding how this process works is key to understanding how information is transmitted over the internet, how to program and build applications that use computer resources, such as memory, storage and equipment, and save and work with data to perform calculations and analysis. Yes or no, on or off, one or…
