Today we started a new topic called peripherals.

We started off the lesson by discussing the point of interfaces. We learned that standardized interfaces were introduced so that people could mix and match peripharels from different companies. When apple came out the only peripharels that worked with their computers were also made by apple. This upset the customers and had to be changed. They later introduced usb ports so other add ons would work. However this meant that all their previous peripharels were uncompatible.

We learned about comparing and contrasting different computer products so that an educated purchase could be made for example looking at shape,size and price. To compare actual products we used the internet to try and find good computers to replace the ones that are already in the classroom.

We did this for the rest of the lesson.
