Von Neumann Architecture Essay

Computer Architecture Sub-Systems

Von-Neumann
The Von-Neumann Architecture that describes a general structure that a computer’s hardware should follow when processing data. The Von Neumann architecture has different entities that it uses to process the information/data. These are input/output (i/o), main memory and the processing unit, which are connect via buses, buses are used to connect all components together in order for them communicate. The processing unit is broken down into several sub-systems these are as followed, Arithmetic Logic Unit (ALU), Program Control Unit (CC), and the Program counter. (Computer Organization I, n.d.).
How does the Von-Neumann Architecture work?
The Von-Neumann Architectures starts from the input, data/programs

RAM is split into partitions, every partition will consist of its own address and will have its own individual contents, the data that is stored in these partitions are in binary form, (Computer Science GCSE GURU, 2017).
How does it work?
By having allocated an address to each partition, it allows the computer to know/identify every location within the memory sub-system. Memory purpose is to (As mentioned in the Von Neumann section of this documentation) to store instruction and hold data, with that data the memory unit will pass on the information to the CC and the ALU, to carry out the calculation and be able to have the data to execute them.
Three types of storage in the memory Sub-system

Input devices are common peripherals such as a mouse, keyboard etc. An output device would be objects such as a TV projector/monitor or a printer. However, with computers they only can handle data/information that is in a digitalised format, which means it much be converted, however with outputted devices they read data in an analogue form so it needs to be converted back to this format before it can be read, some of this information was taken from, (BBC Guides,
