![]() You’ve learned that computers store values only in the form of ones and zeros, the difference between continuous and discrete data, and that computers can only store discrete data. Lets take 101011 and find out it’s decimal representation:\Ĭonverting binary numbers into the decimal system concludes this article. ![]() Remember that the last bit on the left in on postition 0 (also called the least significant bit or LSB). Take every digit and multiply it with corresponding \(2^i\) and sum the up. And the distance \(x\) traveled over time by this car is defined as:\ Think about a car with a constant acceleration \(a\), the velocity of the car is described as a function:\ ![]() The classic physics we perceive in our daily life is continuous. Those ones and zeros are called bits.īut how can those arrays of ones and zeros be used to store complex information? Before answering this, it is essential to talk about the difference between continuous and discrete data. No charge in such a cell usually represents a 0 (or false when thinking back at Boolean algebra), and when a charge is present, it is interpreted as 1 (or true). The storage of a computer, be it a hard drive (HDD), solid-state drive (SSD) or memory (RAM), is fundamentally built out of tiny little cells that store an electric or magnetic charge.
