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 ;)

The CircuitDesign is a feature rich app designed by an engineer. This app allows the creative smart people like you to design, draw, analyse, simplify and solve electrical circuits. You can design, draw, solve and simplify resistor-network, solve capacitor-network, solve inductor-circuit. You can design, draw, solve and simplify parallell circuit diagrams, series circuit diagrams, delta/wye circuit diagrams and any combinations of these. You can convert delta to wye and wye - delta network You can convert current source to voltage source or voltage source to current source You can design your own resistor (3,4,5 or 6 band resistor) or find the value for existing resistor You can even share your creativity with other people. Save the diagram locally. Do you have a complex network involving any combinations of parallell network, series network, delta/wye network? Fantastic. You can simplify this network and see how its done step by step so you can learn how to simplify networks. You can go back all the way to original network to see how the simplification was done. Simply stated, view simplification steps graphically. Keeps the historical diagram so that you can go back and verify each step. You can also share the simplification steps or save it locally. It automatically saves your hard work locally on your device so you can come back and pick up from where you left off as your great effort of drawing diagrams and simplifying/solving it will not be lost. Are you a high school student learning electricity? This is the app for you. Are you a university student learning electrical engineering? This is the app for you. There is also a page to help you study. This study tab teaches you some very important laws of electricity and important formula. Like Ohm, law, Kirchhoff's volgate law, Kirchhoff's current law, There is also a page to help you learn now to use this app. This is a perfect app for a creative smart individual like you. This is an app for all student groups. From high school to college to university students. Be creative. Enjoy the app!
