![]() ![]() If 8 switches are added together you get a byte. The smallest memory configuration is the bit, which can be implemented with one switch. In a computer, switches are implemented using transistors. If someone else then looked at the switches, they could "read" the number. So you think of a number and set the switches on or off to "store" the binary value of this number. ![]() Each switch could represent 1 or 0 depending on whether it is turned on or off. ![]() Imagine if you had a bank of 8 rocker switches just like in the image below. Values are stored in binary format in memory, which is basically a bunch of electronic on/off switches. The digital technology which uses this system could be a computer, calculator, digital TV decoder box, cell phone, burglar alarm, watch etc. Numbers can be encoded in binary format and stored using switches. How Is Binary Used in Digital Computers and Electronic Devices?
