hello,

First of all you need to understand the difference between C language and computer organisation and architecture (COA).

COA deals with the hardware components of computer. You learn lot about hardware stuffs like how they work, what are their key roles etc. In COA lab you will learn how code for the hardwares for this you will learn a new programming language that is VHDL (Very High Speed Integrated Circuit Hardware Description language). This programming language deals all the operations releted to hardwares. They are used for buliding integrated circuits, snadragon all versions, chips, missiles etc.

C Programming Language is a programming language which deals at the software level only because through c language you can never build a program that can control the hardware components of cmputer like integrated circuit.

Both subjects are separate and you will learn all in details throughout the semesters.

hope this will you

all the best!!
