Letter writing: EMPLOYMENT

Dear Mrs. Cairns,


Development Officer, Job Reference No. 5469


I am enclosing my CV in response to your advertisement for the above post which appeared in the Daily Clarion on 15th January 2001.

As you will see I have recently graduated from the Open University with an Honours degree in Psychology. I have been studying part-time for the last six years, as well as working full-time as a Care Assistant and running a home. I feel that this demonstrates my ability to maintain dedication, motivation and enthusiasm for a project over a long period of time. In addition, balancing full-time work with study has honed my time-management and organisational skills. I consider that the study of Psychology is particularly appropriate for the above post, particularly the course on Child Development which explored the personal, social and emotional development of children. In addition, my work on the course Working with Young People taught me a good deal about dealing with difficult behaviour in young people aged between twelve and twenty-five, the age group of Youth in Trust participants.

My current job as a Care Assistant, working in a residential home with young people with additional needs, has given me an insight into the value of work with teenagers, and has underlined my determination to work with this age group. In addition, my voluntary work with the Everett Project, when I organised some sporting competitions during the residential week at a holiday camp for young offenders, has reassured me that I am able to make a significant contribution in this particular area.

From reading your Annual Report I am assured that your work with youngsters who have been identified as being at risk of offending is highly regarded in the community. I would find the post of Development Officer for Youth in Trust very worthwhile and challenging, and I do hope that you will look favourably at my application. I look forward to hearing from you.


Yours sincerely,

Mrs Elizabeth Page

A computer system

The heart of any computer system is the Control Process Unit (C.P.U.). This may be divided into three parts -the Control Unit, the Arithmetic and logis unit, and de main memory.

The Control Unit, as its name implies, controls all the operations of the computer. It generates timing impulses by means of a time clock and sends command pulses to the Arithmetic and Logic Unit. It thus serves as an interface (a link) between the main memory and ALU, interpreting instructions given by the programmer.

The Arithmetic and Logic Unit, which contains wired operators and registers, deals with calculations. The main memory (also called Control Unit) or store), stores both the data being processed and the program that controls the processing. Main memory should be distinguished from auxiliar memory, which is a means of storin (savin) are quantities of data on media such as magnetic disks and magnetic tapes that may be removed from the C.P.U. and fetched only when required. A frontal proccessor may be required to control the flow of data between the CPU and various peripherals.

The CPU is surrounded by peripheral units. Several types of peripheral units can be distinguished, namely input peripheral, output peripheral and input-output peripheral.
Input peripherals, as their name implies, convey the data from the external world to the Central Processing Unit. They include keyboards phot-sensible peus and even microphones, just to name a few.

Outpul peripherals, on the other hand, give the results of the processing of data on devices as VDUs (Visual Display Units) or printers, which are the most common output devices. Input/output peripherals (I/O for short) can be used for both of the above-mentioned functions and an work either way. Typical examples are disk units.

Any such devices directly connected to the CPU are called on line peripherals, as oppsed to offline peripherals such as the obsolete card-punches. Data acquisition consists of editing brute data so that it can be fed into a computer in a form the computer system or mainframe computer, there is usually an interruptible power system, which regulates any fluctuation in voltage from the main power, as well as providing an emergency power supply, should there be a power cut. A power cut would result not only in the breakdown of the computer but also the loss of all the data being processed. An efficient system should also include acondicionate air and dust must be kept to a minimum.

Oral presentation: Nuclear Power

Our energy consumption has increased year by year and we need every energy source we can get.

The use of nuclear power is a more controversial subject.

Critics claim that nuclear power is an uneconomic and potentially dangerous energy source. They also point to the problem of storing radioactive waste, the potential for possibly severe radioactive contamination by accident or sabotage.

Proponents claim that these risks are small and can be further reduced by the technology in the new reactors. They further claim that the safety record is already good when compared to the other major kinds of power plants, that many renewables have not solved the problem with their intermittent power production.

HOW NUCLEAR POWER WORKS

1. Nuclear fission makes heat.
   
2. Heat water to make steam.
   
3. Steam turns turbines.
   
4. Turbines turn generators.
   
5. Electrical power sent around country.
   

Heat is produced in a nuclear reactor when neutrons strike Uranium atoms causing them to fission in a continuous chain reaction.

When the control elements are inserted into the core, more neutrons are absorbed, and the chain reaction slows or stops, reducing the heat.

The heat produced by nuclear fission heats the water and turns it to steam.

The steam drives a steam turbine, which spins a generator to produce power.
