typing to transferring data to remote computers. Inside the processor there are some basic elements the work together to make the processor functional. These elements are as follow: 1. Arithmetic Logic Unit (ALU): This is the main block in the processor and the most important. The ALU is responsible for performing all the computations needed through the processor. When the user‚ for example‚ enters a numbers to add‚ this unit makes the computation and outputs the result to the output devices.

11. Compare and contrast abstract classes and interfaces. Why would you use an abstract class? Why would u use an interface? -abstract class‚ ex: (public abstract class Employee{...}) -For related classes only‚ inheritance (last week examples) -extends keyword -contains both instance and static variables -contains both abstract and concrete methods only An abstract class is only to be sub-classed (inherited from). In other words‚ it only allows other classes to inherit from it but cannot

A CPU processor or central processing unit controls the functions of most electronic products. The CPU accepts the input data‚ processes the information and sends it to the component that is in charge of executing the action. CPUs are also known as microprocessors and are at the center of any computer system. Although CPUs are most often thought of as a computer chip‚ they can also be found in many other electronic devices including cell phones‚ hand held devices‚ microwaves‚ television sets and toys

ANS : 5. T/F - One of the most important functions of the OS is scheduling processes/tasks. ANS : 6. T/F - In terms of total control‚ the OS has the most control of the entire system operation. ANS : 7. T/F – The ALU does not take any action if the output of an operation leads to excess bits. ANS: 8. T/F – An eight bit word can represent up to 256 numbers. ANS: T 9. T/F – Operand data can be logical data or addresses. ANS : 10. T/F
