Program Plan Intro

Components of computer:

Computer has four major components, they are:

Central processing unit (CPU)

Memory unit

Input devices

Output devices

Central Processing Unit (CPU):

CPU plays the key role in a computer by carrying out instructions of a computer program.

It performs all the basic logic, arithmetic, controlling and input/output operations that are specified by the instructions.

The CPU comprises of two units, Arithmetic logic unit (ALU) and control unit (CU).

Memory unit:

Once computer program instructions set are transformed into machine code by CPU, the machine code is stored in memory.

Then the CPU fetches the required data and instructions from memory, perform the required operations and then sends the result and next set of instructions back to memory.

Input devices:

The devices used by the user to feed information to computer, such as a hard drive, keyboard, or a networking card.

These devices get the data from outside world into computer in the way that human eyes and ears bring the data to brain.

Output devices:

Output devices are used by computer to deliver the information to the user, such as a monitor, printer, and speaker.

The CPU takes the machine code present in memory and converts it into a format that is required by monitor’s hardware.

Then the monitor’s hardware alters that information into different light intensities such that words or pictures are seen.

Highlight the main differences between Computer Assisted Coding and Alone Coding with their similarities

Suppose that the MinGap method below is added to the Treap class on Blackboard. public int MinGap ( ) Returns the absolute difference between the two closest numbers in the treap. For example, if the numbers are {2, 5, 7, 11, 12, 15, 20} then MinGap would returns 1, the absolute difference between 11 and 12. Requirements 1. Describe in a separate Design Document what additional data is needed and how that data is used to support an time complexity of O(1) for the MinGap method. Show as well that the methods Add and Remove can efficiently maintain this data as items are added and removed. (6 marks) 2. Re-implement the methods Add and Remove of the Treap class to maintain the augmented data in expected O(log n) time. (6 marks) 3. Implement the MinGap method. (4 marks) 4. Test your new method thoroughly. Include your test cases and results in a Test Document. (4 marks)
