Hello readers👋 Today we will learn about the basics of how a computer system works which will help us to study System design and its use in product management.  Binary Numbers: Our computers understand binary digits (i.e. 0 and 1) to perform various takes inside their system. To convert any binary number into decimal number we consider them as 2^n. Base 2 numeral has 2 symbols: 1 and 0. Both symbols are called a bit - binary digit.                          Example:  The total number of bits we have on our hard drive determines how many bits we can store. 8 bits of 1s and 0s are called a byte                                        01000001 = 1 byte = A (a character)                                        1024 byte = ...
