Programming For Beginners: Defining Byte Data Type

In this video we will talk about "byte" data type in every programming language. If you remember, in the Machine Code video, we said that computer keeps code in the memory in blocks of bits. That is exactly one byte of data.

When we are talking about numeric values, we should remember that we have both positive and negative numbers. So how does a computer identify one? The most significant bit! In this video we will look into the meaning of this word and we learn how to convert binary numbers to decimal values.

Each programming language has its own definition for byte data type. In C based languages like C++ and C#, we have both "signed byte" and "unsigned byte". How ever in Java, we don't have unsigned version and in Python, we only have unsigned list of bytes as the only data type that works with byte values.
