Just learn how to CODE a computer: The very basic principles of any computer. Most people learn how exactly a computer works by buying this App. Learn how to CODE. Tell me how a microprocessor works. Here you can learn it. Please like my App and write a customer review. 4917emu is an hypothetical microprocessor that was used in a computer course named COMP1917 at the UNSW University of New South Wales to teach microprocessor basics. It is 4bit, has 16 memory locations and 4 registers: - Instruction Pointer (IP), - Instruction Store (IS), - General Register 0 (R0) and - General Register 1 (R1). Each memory location can store a number between 0 and 15, and there are 16 instructions. There is a Extended Instruction Code set. For example the following 4917 machine code program would print the numbers from zero to 15: 8 0 3 11 1 15 0. Happy hacking ;)

In the early 20th century scientists wanted to know more about atoms. They knew that atoms were electrically neutral and that for every negative particle there must be a positive particle. The scientist Ernest Rutherford made a massive contribution to our understanding of the nature of matter by suggesting a model which fitted experimental data. ---------------------------------- This app forms a companion to GCSE level / High School Physics for Students and anyone interested in the fascinating experiment that shaped our current understanding of the structure of the atom. An ideal revision aid, or classroom demonstration, Rutherford and the Atom will entertain and teach.
