Even more fundamental than the trusty pixel, binary is the simplest form of data that computers use. In fact, binary is the only way computers can really understand information, so everything they do is translated into this simplest of languages. Binary allows computers to perform extraordinarily complex calculations, interpret patterns, and even understand speech. This lesson introduces your new best friend for understanding the heart and soul of computer science.
- Computers use numbers for just about everything.…Even when it doesn't seem to be a number, it is.…Take letters, for example.…When you type a letter on a computer, it actually has…a numerical value and it's the number the computer records…and reproduces.…But there's an even more fundamental piece of information…computers use and understanding it will help you understand…a great amount of technologies.…It's binary.…In it's simplest form, binary just means…something that has two states.…This could be off and on, up and down, light and dark.…
Anything that has two recognizable conditions.…Computers storage drives generally use magnetism,…if there's a magnetic charge or not.…Though, it's not all that important for our…purposes how the binary's recorded.…What matters is that the numbers we get from these…systems will either be zero or one.…And it's always zero or one.…There are some clever quantum computing systems…that do things differently and they've…experimented with recording a zero, a one, and a two.…But for our purposes, and for the purposes of pretty…
Get ready to remove the mystery behind terms you've encountered. If you work in a creative profession, this can enhance your command of the tools you use. Learn what a pixel really is, what color channels are, and what audio frequency is. Discover how color channels, bit depth, and video frame rates work. Find out the difference between codecs and file formats, and how compression is involved. By the end of this course, you'll know how to answer common client questions—like, whether a logo should be supplied in vector or bitmap form, and more.
