First came the black and white TV, followed by the revolutionary coloured TV. At the same time there were black and white photos followed by coloured ones, which only improved in terms of quality over time, as did the coloured TVs. Interestingly enough, black and white photos “came back” with the digital age, when with the click of a button a photographed image could be turned instantly into a black and white picture for a more vintage look. Although there is something to that, and a need for solely black and white pictures and documents from time to time, today, we mostly need and want for items printed to look precisely the way they do on the screen.

For a long time, having a document printed in colours consisted of a lot of expensive ink. Today thanks to laser printers, one can easily print unbelievable, high quality pictures and documents from their own home. Pictures can look just as good on a piece of paper as they do on professional photo paper from a photo store. Bold, clear colours are quickly transferred from digital version to a physical piece of a paper with the amazing colour printers available today. There is a wide range of these printers available, including the Duplex colour laser printer. There are many other manufacturers of printers as well as models to choose from. Having a colour printer at home saves many trips to the copy store. Almost any printing can be done at home this way. Laser printers are leagues above the original, black and white ones.

Remember when you had to reboot each time you plugged some peripheral device through your computer ports otherwise they wouldn't be recognized at all? Enter the Universal Serial Bus(USB). USB connected devices have the ability to be hot-swappable and recognizable without needing to reboot the operating system which is why USB’s are now the connection of choice for most modern devices.

Aside from simply providing the physical connection, USB’s also provide electrical power to the device. USB’s also have the ability to provide multiple extensions, with each one separately recognizable by your computer. Thus, even if your central processing unit only has 2 USB sockets, you can plug USB extensions when you need to connect more and more devices to your computer.
