Suppose you are an operating system designer and have been approached by the system administrator to help solve the recurring deadlock problem in your installation’s spooling system. What features might you incorporate into the operating system so that deadlocks in the spooling system can be resolved without losing the work (the system processing) that was underway or already performed by the deadlocked processes? Discuss using a short essay summary to explain how you go about solving deadlock problems.

Three dry cells each having internal resistance of 0.50 and an e.m.f of 1.5V are in series with a 1000 Blatooth, a 1000 wifi module both in parallel and a 350 GSM modules to form a simple telephone circuit. The connecting wires have a total resistance of 20 and low noise amplifier of 300. Compute the low noise amplifier voltage (4marks] b) Three ruszors, two of 4K8 boch in parallel and a third one, are connected in series. A fourth resistor of 4M5 and fifth of twice the value of the third resistor together in series are connected in parallel with this circuit. The equivalent resistance of all the five resistors is given by 3KS L Calculate the value of the third and fith resistors. H. If a banery with eaf of 20V is connected to this final circuit, calculate the curcax through the fifth resistor Repeat for capacitors. [6marks]

Write a graphical user interface for an application, website, pc game, mobile games or any application that you want to develop someday. Have a short description of what the application is all about and describe each object on the GUI. In laymans term, a GUI is the overall appearance or look and feel out an application that the user is interacting by pressing a button, image or any object on a screen.
