Computer hardware refers to the general physical implements used to assist the functioning of a computer process. The hardware categories are separated into three categories: inputs and outputs and storage. Inputs refer to hardware that provides data that go into the computer system and outputs are data that goes out of the computer and storage refers to the hardware that contains and stores data information.
2.What is Moore's Law/what does it mean in relation to computers.
Moore's law states that the number of transistors on an integrated circuit, doubles every two or so years, causing a exponential increase in the performance of computers over a period of time. However this law is applied generally and other variables can cause an increase in performace of computers. The graph below show the relation between time and number of transistors causing the increase in computer technology.

The microprocessor is basically the brains of the computer. the microprocessor is also refered to as the CPU and the processor. It is composed of series of transistors or semiconductors, (usually silicon) that are arranged on an integrated chip. Currently computers use solid state transistors and earlier computers used diodes or valve transistors. The CPU receives data and instructions and the processes it to the correct function.

The main factors that determine the speed if a computers microprocessor is the number of instructions per second the processor can execute. It is measured either in megahertz (MHz) or gigahertz (GHz) per second.
5.What are the four main types of primary storage?
The four main types of primary storage include the RAM (Random access memory), the register (or CPU), Cache memory and the non-volatile read-only memory (ROM). Primary storage normally deals with the functioning of the processing of the computer.
4.What are the main types of secondary storage?
The main types of secondary storage are the Hard drive, flash drives, CD and DVD, Blu-ray discs and SD cards and now recently online storage. Secondary storage refers to permanent long-term storage.
5.How does primary storage differ from secondary storage in terms of speed cost and capacity?
Primary storage differs to secondary storage that it has faster speeds but lower capacity, and vice versa in terms of secondary storage. However is primary storage reaches high capacity in storage the computer speed is slowed down.
6.What are enterprise storage systems?
An enterprise storage system is an online storage system that caters for large scale businesses. Enterprise storage systems stores the data on an off-site location form the business. This insures the business protects its data from natural disasters and from data loss.
7.Distinguish between human data input devices and source data automation.
Human data input devices are data that has been transcribed by humans and placed into the computer. This is done through input devices, such as: keyboard, mouse, microphone etc. Source data are digital data that is placed onto the computer. Source data reduces human error and is particularly used for repetitious data logging.
8.What is one new technology that will change how we do things? You need to do some research.
A new technology that is currently being implemented is the interactive table/ keyboard. This will enable programmers to specifically tailor make the keyboard with specific buttons with their associated program. This tabletop can have potential to increase efficiency with the business context as the customer can interact more efficiently with the computer than an operator.
