Changes in technology over the years

Technology has changed drastically over the many years on the design and creation of graphic images and is continuing to change. This change has made our lives of use technology easier by being better and easier to use.

Mobile phones: This is one that has a huge change from years ago. They were “Bricks”, as many call them, with an aerial on the top. They had no screens on them, just the number keys. They also had a lot of static and noise interference and were less reliable. In the late 1940’s, they had the idea of using of something to communicate with others was created. The first mobile phones were used for police and taxis to be able to communicate. This spread wide to what it is today, to be able to communicate with everyone we meet. Mobile phones we use today are small enough to fit in our pockets and have screens to display the images. When the first game on a mobile, Snake, came out, everyone thought it was amazing and they wanted to get it. Now, phones can play many games. They can access the internet, play games, take videos, play music, take pictures and many other incredible things that no one imaging it could do. We expect phones to have good graphics, like being able to use models for games and colours, unlike when the first mobiles started to come out, where it had a green background and black pixels. All phones have to be able to use all these different things, like Facebook and other internet sites or they will be sent back. Mobile phones have a camera and can take pictures. As the phones got better, so did the images with better quality and higher resolution making the images have better colour quality and looking smoother. These pictures can be used on a computer on editing software. Because of the better quality, the images are much easier to edit on these software’s.












Printers: Printers have also changed. They used to produce images with such a low quality, but when compared with today’s printer, there is a big difference. Our printers today produce images with a high quality, which brings out the colour and makes printed images look smoother. They began being manually controlled and very slow, but then changed to be automatic and being ran from steam. These were used in commercial printing companies who could afford them. Printers then started getting faster and the quality images they produced got better. Their prices decreased, allowing everyone to be able to afford a printer. Today’s printers are paired with the computer to work better. There are also many different types of printers to be able to produce images from, such as laser printers and ink jet printers. Prints are now able to print 3D. To do this, you make a 3D graphic and print it out as a solid object. This has even have been used to replicate areas of the human body to help those who have lost parts of their body that they have lost. They say in 5-10 years, we will all have 3D printers in our homes.









Computer monitors: These used to be big and clunky, with a screen that would come out slightly and a back that was huge. Today, our computer monitors have a flat screen and a small back. Image quality on the monitors has changed. They first used to be black and green, which used to hurt people’s eyes. These were known as CRT monitors, which stands for cathode ray tube. This made them very dangerous as it released poisonous gasses if the computer was left on for too long. Better quality computers do not have any harmful chemicals in then and are safe to use. Most computers now are LCD which stands for liquid crystal display. You can see the liquid if you press against the screen. This ensures the quality is always high. LED, which stands for light-emitting diode, monitors emit a light at the back which reduces the size and increases quality. It is better for graphical users to use LED monitors because of the increased resolution of the pixels. The graphics in computers have gotten better as they could only have pixels but are now able to use models for games and designing. Some monitors are touch screen, meaning you do not need a mouse to click things as you can touch them and may not even need a keyboard as the keys can appear on screen to touch.

  1. You have got some good information about mobile phones and how printers are different compare to the first printers invented. You could talk about a problem that could occur if technology keeps improving.
