This report will explain the functions of such as the Central processing unit (CPU), random access memory (RAM) and the graphics processing unit (GPU).
Task 1
CPU is the part of the computer which performs all of the calculations and logic; it also controls data flow and other parts of the system. The CPU is made of silicon transistors which turn on and off to represent 1’s and 0’s. The CPU has a core clock this tells the processor how many times a second to turn off and on each transistor, for example a core clock of 3.6GHz tells the processor to cycle 3.6 billion times a second this allows the computer to perform computations extremely quick.
The motherboard is the component which connects all of the other components together it also has basic chips on it such as the BIOS (Basic input output system) chip this provides basic functionality to the components and tells the PC what to do when the power is pressed. The motherboard also provides power surge protection to the components along with chipsets and various other micro-controllers.
Power supply is the component which converts the AC from the wall to DC which can be used in the computer. The power supply also provides some surge protection and has redundant capacitors if the power is cut so volatile memory can be emptied into non-volatile storage such …show more content…
For example the fan placed on top of the CPU and GPU heatsink is designed to draw heat away from the heatsink. However case fans can be positioned in such a way to draw heat from the front and out the back or top to maximise air flow and efficiency. Depending on what your computers purpose is different types of fans can be used for example fans with larger surface area fins can be better in low noise situations and also perform better when pulling heat from heatsinks, however fans with more fins but a smaller surface area can move more air through the case and perform better

Learners will use their knowledge of relevant human resources management theory and link it with current human resource management practices in organisations. Unit introduction Human resource management is a dynamic activity in any organisation as it takes place against a changing economic, technical, legal and social background. It is important for learners to appreciate that effective human resource management means getting the best out of the people who work for an organisation in order to ensure the organisation fulfils its purposes, whether it is a football club winning the premiership, or a hospital increasing the success rates for medical operations. Many organisations say that their employees are their most valuable resource because of their skills, knowledge and attitudes. As labour is both an expensive and valuable resource, it is important to ensure it is planned and that the best value is obtained from employees contributions.

Unit introduction It is important, when working in business, to ensure compliance with organisational procedures and legal requirements, as the consequences of non-compliance can have serious implications for employees and employers. It is important, therefore, for learners to appreciate that those working in business must understand the principal issues which affect the working environment, for all individuals and the organisations that employ them. This involves keeping up to date with information on the legal issues that affect safe working practices. Everyone at work plays an important part in ensuring health and safety and it is essential that key personnel are aware of their roles and responsibilities. Employers must take reasonable care to protect their employees, and others, from the risk of injury, disease or death, while employees must take care to protect themselves and others. Safe working conditions and the ‘welfare of employees’ can contribute to the success of an organisation. It is important that organisations take steps to prevent accidents...
