# Digital Principles and System Design

Systems design implies a systematic approach to the design of a system. It may take a bottom-up or top-down approach, but either way the process is systematic wherein it takes into account all related variables of the system that needs to be created—from the architecture, to the required hardware and software, right down to the data and how it travels and transforms throughout its travel through the system. Systems design then overlaps with systems analysis, systems engineering and systems architecture.

An important drawback of binary system is
What is the addition of the binary numbers 11011011010 and 010100101?
Perform binary addition: 101101 + 011011 = ?
Perform binary subtraction: 101111 – 010101 = ?
Perform multiplication of the binary numbers: 01001 × 01011 = ?
Divide the binary numbers: 111101 ÷ 1001 and find the remainder
