  1. As a firm grows the lines of communication are often stretched.

    The problem with this is that it may clash with another objective, Profit. If the company is to spend money on a new communications system it must make sure that the money spent on the system, staff, marketing etc, does not overshadow the money made by sales and other sources of profit. This, although a big problem could have benefits in the long term. If the money spent on setting up the Communications System is more than the profit made that month. In the months after when the System is set up, the benefits in profit as a result of the it being set up could be far greater than that in past

  2. Why did regional variations exist in the prosecution of witches between 1560 – 1620? Give examples from at least 3 countries to support you answer

    The main three countries that I will be focusing on in this essay are England, Germany and Scotland. This is because they are all countries full of examples and contrasts in the way they prosecuted witches. England, famous for its Essex trials, which were the biggest in the country, will prove to be a very good example of how the hysteria of witchcraft spreads around Europe. Germany on the other hand is a country, which is famous for a large amount of hunts in their country, such as in the south of Bavaria.

  3. Using examples, discuss the advantages/disadvantages of proportional representation systems compared to the ‘first past the post’ system as used in parliamentary elections in the UK.

    Whether or not plurality is the best system has long been debated. By 1920 Britain was the only democratic country in Western Europe not to have adopted some form of PR (Hain 1986). Advocates of the plurality system, including Peter Hain (1986), besides arguing that the plurality system is the simplest system, maintain that it's preferable to alternative systems for other reasons. Without needing to put down multiple choices, the ballot paper is easy to fill in. The ability for voters to make decisions about clear political policy programmes means elections revolving around the candidates' personalities are discouraged.

  4. Describe how you would set up and maintain a wireless LAN alongside an existing wire-based system in a closely defined organization of your choice’

    Another popular one is Bluetooth, operating over 2.4 GHz and data rates of 1Mbps. Wireless LAN's use electromagnetic airwaves (radio in this case) to communicate network information from node to node without relying on a physical (wired) connection. The various manufacturers of wireless LAN's have a range of technologies to choose from. The common ones include narrowband (NB), spread spectrum (SS), frequency hopping spread spectrum (FHSS), direct sequence spread spectrum (DSSS) and infrared technology (IR). The principal one used in our solution is FHSS.

  5. Explain the function of computer hardware components

    Processor The processor more known as the CPU (Central Processing Unit) is a small chip; it is the main intelligence of the computer and controls everything that happens within the computer. The processor receives an output and input, and the processors job is to provide the correct output so that tasks can be completed by the user. The CPU gets instructions from the RAM (which is the input), reads and processes it and then sends back the data so that the relevant components can carry out the instructions. The speed of the CPU (central processing unit)

  6. Discuss the Causes and Effects of the Digital Divide

    Less economic developed countries do not have really a point of buying computers because of their low literacy rate because they would know how to even use it. Some places in some countries like Nigeria do not even have consistent power supply so there is not really a point of having a computer because u will not be able to use it when they need to. The people who usually have all the latest technology are the ones who have a better standard of living they are usually more happy than people who do not have the latest technology because

  7. Businesses now have to take certain precautions to ensure theirs and customer data is safe and not under threat

    Your card details will only be used when making a transaction. A customer always has the option to whether they want to stop emails or would like their data removed from the system. Hacking There are many risks when entering your personal details into these websites as you can never be sure that the security is efficient. Unauthorised users can access these details by logging into the network security system from outside or just taking the information if they work on the inside.

  9. ICT revision notes - IT project management

    âEach task should be clearly defined so a member of the team could take it away and work on it. Allocating Tasks âOnce the tasks have been identified, the next step is to allocate the tasks to different people in the team. âNeed to be in a sensible sequence âNeed to give tasks to those with the most appropriate skills.
