Task 1 Part 1: Diagram of Von Neumann Model of a Computer

Part 2: Examples of the input, output, and memory sections of the model.
Von Neumann divided a computer’s hardware into 5 primary groups:
1 CPU
2 Input
3 Output
4 Working storage
5 Permanent storage

Concept Explanation Binary data
Data, be it instructions, user data or something else, which has been translated into sequences of 0’s and 1’s. Bus width The size of the packet of data which is processed (e.g. moved) in each work cycle. This can be 8, 16, 32, 64, 128 or 256 bits. Band width
The data transfer capacity. This is measured in, for example, kilobits/second (Kbps) or megabytes/second (MBps). Cache
A temporary storage, a buffer. Chipset
A collection of one or more controllers. Many of the motherboard’s controllers are gathered together into a chipset, which is normally made up of a north bridge and a south bridge. Controller A circuit which controls one or more hardware components. The controller is often part of the interface. Hubs
This expression is often used in relation to chipset design, where the two north and south bridge controllers are called hubs in modern design. Interface
A system which can transfer data from one component (or subsystem) to another. An interface connects two components (e.g. a hard disk and a motherboard). Interfaces are responsible for the exchange of data between two components. At the physical level they consist of both software and hardware elements. I/O units
Components like mice, keyboards, serial and parallel ports, screens, network and other cards, along with USB, firewire and SCSI controllers, etc. Clock frequency
The rate at which data is transferred, which varies quite a lot between the various components of the PC. (Usually measured in MHz.) Clock tick (or clock cycle)
A single clock tick is the smallest measure in the working cycle. A working cycle (e.g. the transport of a portion of data) can be executed over a period of about 5 clock ticks (it “costs” 5 clock cycles). Logic
An expression I use to refer to software built into chips and controllers. E.g. an EIDE controller has its own “logic”, and the motherboard’s BIOS is “logic”. MHz (Megahertz)
A ”speed” which is used to indicate clock frequency. It really means: million cycles per second. The more MHZ, the more data operations can be performed per second.
North bridge
A chip on the motherboard which serves as a controller for the data traffic close to the CPU. It interfaces with the CPU through the Front Side Bus (FSB) and with the memory through the memory bus.

Protocols
Electronic traffic rules which regulate the flow of data between two components or systems. Protocols form part of interfaces.
South bridge A chip on the motherboard which works together with the north bridge. It looks after the data traffic which is remote from the CPU (I/O traffic).

Input is the user setting a binary code into the read only memory (rom) Eprom chip and also into the read all memory (ram) Eprom chip through the keyboard which is the set as a value to an assigned letter delivered to the screen as an output that is stored into these chips.

Task 2

PART 3: Provide a comparison table showing the similarities and differences between desktop and notebook computer.
