Question Solved1 Answer A computer uses RAM chips of 1024 x 1 capacity. (1) How many chips are needed and how should their address lines be connected to provide a memory capacity of 1024 bytes? (ii) How many chips are needed to provide a memory capacity of 16K bytes?

1. Write a program that reads a number between 1,000 and 999,999 from the user, where the user enters a comma in the input. Then print the number without a comma. Here is a sample dialog; the user input is in color: Please enter an integer between 1,000 and 999,999: 23,456 23456 Hint: Read the input as a string. Measure the length of the string. Suppose it contains n characters. Then extract substrings consisting of the first n - 4 characters and the last three - characters.

Partial differential equations Please provide the answer with steps. Consider Laplace's equation \[ \nabla^{2} \phi(x, y)=0 \quad \text { where } \nabla^{2}=\frac{\partial^{2}}{\partial x^{2}}+\frac{\partial^{2}}{\partial y^{2}} \text {. } \] Show, using the method of separation of variables (and not direct substitution), that solutions inside a square box with sides of length L can have the following forms: \[ \begin{array}{c} \phi=\left(A_{o} x+B_{o}\right)\left(C_{o} y+D_{o}\right) \\ \phi=\sum_{n}\left(A_{n} \cosh \frac{n \pi x}{L}+B_{n} \sinh \frac{n \pi x}{L}\right)\left(C_{n} \cos \frac{n \pi y}{L}+D_{n} \sin \frac{n \pi y}{L}\right) \\ \phi=\sum_{n}\left(A_{n} \cos \frac{n \pi x}{L}+B_{n} \sin \frac{n \pi x}{L}\right)\left(C_{n} \cosh \frac{n \pi y}{L}+D_{n} \sinh \frac{n \pi y}{L}\right) \end{array} \] [Hint: use \( A e^{k x}+B e^{-k x}=\frac{A+B}{2} \cosh k x+\frac{A-B}{2} \sinh k x=A^{\prime} \cosh k x+B^{\prime} \sinh k x \) ]
