Take a deep dive into the way computers work. The simple elegance and robustness of the system with which computers turn simple 1s and 0s into regular numbers is at the root of all more complex computer-based technology. This video primes you to understand a huge swathe of more complex technologies, from visual design to sound recording.
- [Instructor] So, how do these two numbers…give us the incredible range of things computers can do?…The first thing we need…is a way to turn these zeroes and ones…into bigger numbers.…A single zero or one is called a bit.…We need bytes.…A byte is eight bits.…It might sound a bit complicated when you first hear it…because it's such an unusual word to use,…but bits and bytes are the building blocks…of the computer world.…The system is so simple and so elegant,…it makes computers work robustly and dependably.…
And it works like this.…If you line up a set of eight binary bits,…you can assign each one a number.…The numbers used start at one and double each time…until they get to 128.…So, we have one, two, four, eight,…16, 32, 64, and 128.…And let's just say that zero means off…and one means on.…So, if a binary bit is on,…we'll add that number to any other numbers that are on…to get any number from zero to 255.…
Let's try this out.…All zeroes would make zero.…If the first binary bit is on, we'll have one.…If only the second binary bit is on, we'll have two.…
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.
