What are the main components of a digital computer?
What are the main components of a digital computer?
The main components of a digital computer are the CPU, memory, and I/O devices.
Explain the purpose of a compiler in computer languages.
Explain the purpose of a compiler in computer languages.
A compiler translates high-level programming code into machine code, making it executable by the computer.
What is the significance of Gray Code in digital systems?
What is the significance of Gray Code in digital systems?
Gray Code minimizes the risk of errors during transitions between values because only one bit changes at a time.
