Fundamentals of Computer Architecture

Only thing it responds to is an electrical pulse or no electrical pulse
2 states it responds too, so we use a binary system
0-bit
1-bit
Combination of 8 bits is called a byte (megabyte, gigabyte, terabyte, etc...)
byte is a unit of memory
every symbol on a keyboard is called a character
each character is represented by a combination of bits
A - 01010011
Compiler
entire code translation
takes a source code, points out any errors, and when the entire code is correct, it converts the source code into a machine language/binary code/binary language/object code
Interpreter
line by line translation

source code --> compiler/interpreter --> object code
java, c++, etc...                                         01010011010

operating system is a system's program that helps us to work with all the resources of the machine
application software - third party apps that have a specific purpose
