"VHS is dead, long live DVD".
3 star(s)This obviously means that the way we view films, music etc is getting smaller and also means that it will continue to decrease in size. Even though a video is larger than a disc it does not mean that it holds more memory, in fact a disc holds seven times more memory than a video, which is the main reason the DVD has taken on. The word 'Digital' has great benefit over the VHS because videos are predominantly analogue and all DVDs are digital.

Hardware used in my created system - inputs and outputs
Mail merge automatically moves the data from where we input it into our wage slip which will be printed, which is our output. Each part of my system needs hardware. The input which is the data requires a keyboard. Storage requires a hard drive, obviously. The process requires a CPU and RAM to function and the output (wage slip) requires a printer & monitor. My system can be described as a number of subsystems. The wage slip is a system in itself, having the spreadsheet as input data and storage, the actual mail merge being the process then the wage slip being your output.

The development of computers and their uses.
Pretty soon, many calculators/computers were being made. Computers changed the world a lot. It helped man step forward into the future. Thanks to computers, space exploration came true, new designs of vehicles and other transportation were made, entertainment became more entertaining, and medical science made more cures for diseases. The computers impacted our lives in many ways. You may not notice it but they did make life a lot easier. Without computers, the world would be a harder place to live in. Thanks to the computers, everyday life is easier for us. Some people may disagree but most would not.

Choosing Hardware. he computer system that is already installed will not meet the Theme Parks requirements because it is inadequate. The RAM (system memory) is about 4000 megabytes too small and would only last for a very short period of time
out visitors' photos quicker than the old system and prevents annoyed customers having to wait for their souvenir photos, thus increasing business. I would suggest upgrading to "HP Touchsmart 600". With a touchscreen, there is no need to have a mouse. It is 10 times quicker, for the particular requirements the Theme Park will need - which is an improvement over the old VDU. It has an Intel Core 2 Duo Processor which is an improvement on the old system.

Different Types of Output Devices.
These use tiny crystals which block the light from passing through them. Colors are obtained by using a combination of special filters. TFT (Thin film Transistor). This is more advanced type of display, giving full color and a high- quality output. It provides a higher resolution and more contrast than an LCD screen. Printers After the monitor, the second most common computer output device is the printer. Printers can be connected to an individual computer or to a network and shared by a number of computers. Printing out work from the computer is referred to as obtaining a hard copy.

Hardware and Software Report
A report done by The Economist shows this could be why BA's sales have been dropping gradually over the past decade. This logo represents the British based airline; Monarch. This logo uses two complementary colours, which are purple and yellow. The crown image is very clever because it matches the name of airline. The colours are used to great effect on the crown, the middle part of the crown is filled in with a golden yellow, and the two sides match the purple font.

Types of computer systems - Notebooks (Laptops) These are little, light and simple to carry around.
Minicomputers are used by smaller businesses to handle their data processing or to run something similar to a city traffic control system. Desktop computers would naturally be supplied with the computer itself (complete with hard disk drive and floppy disk drive) and peripherals such as a screen, a mouse, a keyboard and a CD or DVD drive. These are comparatively cheap and easy to add development cards to.

IT GCSE Project 1: Hardware
Hardware There are specific requirements for my data handling system software to be ran by my hardware efficiently. I have looked through various types of adverts like over the internet, newspapers and magazines to find a system that fits my requirements. * I require the speed of the processor to be 800 Mhz i thought that this was standard, the reason I did not increase this was because it is reasonable for my database. * I require the RAM (random accessing memory)

Hardware Justification
It costs; �428.99 including VAT and shipping from Dell: http://configure.euro.dell.com/dellstore/config.aspx?oc=d045001&c=uk&l=en&s=dhs&cs=ukdhs1&kc=segtopic~winxp_inspndt RAM (Random access memory) RAM helps the database to work at an acceptable speed and I recommend 64MB of RAM as the system will need plenty of memory for storing its data, if a Windows XP operating system is used, as my end user also needs the database to work fast for the business to function efficiently. Hard Drive The only use for the computer is to run MS Access 2003 and other Microsoft applications such as word processing as well as internet explorer/email, so there is no need to buy a hard drive with an excessive amount of storage which won't be used, this would increase the price of the computer.

Advantages of using Simulators
A simulation is when a model is used to carry out an activity that copies real-life occurrences. For example, when a bridge designer uses a model to simulate what will happen when the bridge is actually used. A computer model is created using programmed instructions and equations. An example would be a computer model of the way an aircraft behaves when it is in flight. There are different types of Computer Model, they are as follows; 1. Computer-Aided Design (CAD), this is used to create a graphical image of an object based on data fed into the package by the user.

designing an information system
Input devices must be fast and accurate. The cost of the product must be reasonably cheap. The main input devices in use today are: Keyboard Web Camera Joy Stick MICR Mouse Scanner Digital Camera OCR/PMR Barcode Readers Microphone An optical wheel mouse is available to me and a QWERTY keyboard. Keyboard Keyboards are the oldest and most familiar type of input device. The way a keyboard works is that each button that is being pressed closes a switch. This releases a code which the computer converts to the relevant character. The keyboard is called a QWERTY keyboard due to the letters on the top right of it.

This has every key and letter place to suet us to give us the most comfort. This it is not wireless and that it cant be moved far form the computer and there are only letters and numbers on it and most of the functions of the keyboard are hidden. It is only in English so other languages could not be typed in by this qwerty keyboard. I could have used a concept keyboard which would have been even simpler to use. Mouse The advantage if using a mouse is that it is very simple to sue and has two buttons.

I will also need a RAM (Random Access Memory) of at least 512KB. I will need this in order for my database to work quickly enough and sufficiently enough for the needs of my end user. I also do not need too much memory, as I would then be wasting large amounts of this. Further hardware that I need is a ROM (Read Only Memory) or a Hard Drive of at least 60GB. I will need a hard drive this size in order for my database to work quickly and sufficiently enough for the needs of my end user.

What is Software Piracy?
The consumer cannot afford to buy all the software's of the market in order to have a complete opinion of which one is the most appropriate for the working sector, because usually the software's have a demo edition in which the most important components are disabled. * Easy to Acquire: Pirated software is extremely easy to find, whether online, or sold openly in foreign countries, or simply provided by friends. In fact, in many cases, it easier for someone to go online and download an illegal copy of a software program than to drive to a store and buy it from a retailer.
