Computer

What is a Computer? For most people, a "computer" is a personal computer, or a PC. A desktop PC. They may count laptops and notebooks within their definition of computer, but it usually stops there. If we want to be technical, the computer includes a lot of other things as well. Most importantly, smartphones are […]
Hexadecimal Numbers

Besides binary numbers, another type of number commonly found in computers are the hexadecimal numbers. You may encounter them when talking about colors, RGB, RGBA, memory addresses in a computer, or even editing the bytes of a file with a hex editor. But what are hexadecimal numbers? How do they work? Hexadecimal numbers, or numbers […]
Data

The easiest way to think about data is to think of data as records, as registers. Every time something is recorded, that is data. This record could be some numbers and measurements that we wrote down. It could be a transcription of what someone said. Or we could have recorded the audio or video of […]

That is, programs made out of bytes are software, and everything that isn't made of […]
Bit

The bit is the smallest amount of data that a computer can understand and manipulate. A single bit can only have two possible values. Think of the bit as a lamp being turned "off" or "on," except it's an extremely small lamp. We can interpret this off-on signal in various ways: "off" could mean "false," […]
Byte

The byte is an unit used to measure computer file sizes and data sizes. Just like grams measure weights and meters measure distances, bytes measure data. A single byte is equivalent to 8 bits. A single byte can contain enough data to represent a binary number from 0000000 to 1111111, which is equivalent to a […]
