Relationship between hardware and software Software and Hardware work together to process the input. The CPU (Central Processing Unit) processes input into output through the fetch-execute cycle. Download whatsapp for blackberry torch 9810. The CPU is made up of several different parts including: Arithmetic and Logic Unit (ALU), Control Unit (CU) and various registers. We explain The Relationship Between Hardware and Software with video tutorials and quizzes, using our Many Ways(TM) approach from multiple teachers.

• Personnel or people are the users of the system
• Data are the individual facts represented by binary code that are input into the system
• Hardware is the physical units of the system
• Software is the programs or sets of instructions that control the processing and movement of data within the computer system
• Procedures are the sets of instructions that specify what processing is to be performed.

• The Arithmetic and Logic Unit performs calculations
• The Control Unit loads and executes instructions
• The current instruction is stored in the Instruction Register
• The other Registers store the results of calculations (Accumulator) and where the next instruction is to come from (Program Counter)
• Communications between the CPU and memory occur using Buses - Address Bus, Data Bus, and the Control Bus

• Fetch: The instruction is retrieved from memory and decoded in the control section. The address bus conveys the address to the memory controller that selects the cell address in memory containing the instructions
• Decode: The instruction at the address is sent on the data bus to the decoder where it is decoded into an opcode (is the instructions for processing the data) and an operand (data which needs to be processed). The opcode is sent to the ALU (Arithmetic Logic Unit). The operand goes on the address bus to the memory controller that retrieves the data from the memory cell. This data is sent on the data bus.
• Execute: The processing section carries out the decoded instruction, sending data to or from memory as needed.
• Store: The result of the ALU's calculation is stored in the accumulator.

• Sequential Programming is a step-by-step, logical process. Third generation languages such as Cobol, Fortran and Pascal follow this process. They are good for solutions that require a procedural approach with a distinct begin and end. On the negative, their construction is labour intensive, modulisation is limited, the computer dictates what the user must do next, and the program is unable to react to changed situations quickly and cost effectively
• Event Driven Programming – The execution of an option triggers an event to occur. Fourth generation languages such as Visual Basic, Prolog, SQLs, Hyperscript use this method. They are non-procedural. Generally speaking the user has control of what happens and when. Typically used with graphical user interfaces. Advantages include low maintenance, easier for non-programmer and beginner programmers to learn and follow. They are able to be used on multiple processors and extremely good for prototyping. Disadvantages include careful design and planning and an intimate knowledge of the needs of the client and the actions of the user. Extremely good when external devices are attached to the computer.
