As well as being regulated by statute and common law they are governed by the principles of corporate governance which are laid down in The Combined Code.

  7. This technical report will look at various different memory devices and how they are implemented in a standard computer system. Internal memory devices such as ROM, PROM, RAM, SRAM, DRAM, SIMM and DIMM will be looked

    Data that is stored in memory is generally only kept there on a temporary basis. The term "memory" identifies data storage that comes in the form of silicon chips, and the word "storage" is used for memory that is stored on disks or tapes. Moreover, the term "memory" is usually used as shorthand for physical memory, which refers to the actual silicon chips capable of carrying data. Some computer systems also have what's called "virtual memory," which expands physical memory onto a hard disk. Read-Only Memory The first memory device that will be looked at is ROM (Read-Only Memory).

    This is situated on the right of the keyboard and serves two functions. Firstly, to move the cursor and secondly to type numbers into the computer. The keys on the keypad usually contain the numbers 0 to 9, the decimal point and the mathematical symbols. The key marked "NUMLOCK" is used to tell the computer if the pad is used to enter numbers (NUMLOCK ON) or to move the cursor (NUMLOCK OFF). Input - The Mouse A mouse is a device, which can provide an alternative to the keyboard. The mouse itself has a small ball in its base which, when pulled across a smooth surface, moves a special "cursor" across the screen.

    Virus Types and What They Infect Viruses come in many types; written using many different infection strategies. A virus is a program which reproduces its own code by attaching its self to other programs in such a way that the virus code is executed when the infected program is executed. Viruses do this without the permission or knowledge of the user. Viruses have multiple characteristics and fall into multiple categories. > System Sector Viruses These infect control information on the disk itself. > File Viruses These infect program (COM and EXE) files. > Macro Viruses These infect files you might think of as data files.

    As every action has a purpose behind it, reviewing the literature is no less. Firstly, it gives the researcher the idea of how to go with his research, for example, which method of data collection to use, the research design, key issues and so on. Secondly, if the problem has already been solved by previous research successfully or not? The researcher needs to spot what areas have been covered by previous research and what methods have he/she used, and keeping that in mind, he needs to do research on what has not been covered.

  16. I.C.T. coursework on Computer games retail store.

    I interviewed the manager of the store, Mr.G Grewal and asked him a series of questions about his current system and the system he wishes to install into his shop. I also made a questionnaire for the employees, asking them what they think would help run the store more efficiently. Their current system is too slow, and its distracting the customers away from 3G. The system is not always accurate, and it is not time-efficient. In addition, with the amount of time it takes for the employees to order and count the stock, they must be paid much more than need be.

  17. How audio products work.

    A CD holds about five times more data (650 megabytes in data mode and 740 megabytes in audio mode) than a Minidisk. However, both CDs and Minidisks can store the same amount of music (75 minutes or so). The difference is that a Minidisk uses a digital compression technique called ATRAC (Adaptive Transform Acoustic Coding) when storing music. A recordable Minidisk is a magneto-optical device capable of storing 140 megabytes of information. Music can be scattered all over the disk and the player can "put it together" correctly when playing the disk.

  18. Review of the article "Supply Chain Analysis at Volkswagen of America".

    The main argument is that the present system was not designed to maximize profit for the whole system, but only to realize cash flow for the original manufacture. That is, the interest was only the benefit of manufacture rather than benefit for Volkswagen and dealers in the United States together. The existing distribution system in the United States "has a single dominant form, in which the original equipment manufactures (OEMs) inventory and sell new vehicles to franchised sellers." So, the dealer was a primary customer for a Volkswagen, and the dealer was a supplier to the end user.

  23. Primary or Secondary Storage.

    This uses memory chips and is the fastest but is the most expensive type of storage. A memory chip is a chip that holds programs and data either temporarily or permanently. The categories of memory chips are Random Access Memory (RAM), Read Only Memory (ROM), Cache memory and buffer memory. RAM RAM or primary storage, is located in RAM chips physically close to the CPU. The architecture of RAM is similar to that of mailboxes at a post office. A RAM chip is made up of addressable locations (cells). Whenever a CPU writes data, instructions or information to RAM, it wipes out the previous contents of RAM.
