Five confusing IT terms?


Struggling with 'geek-speak'? Here are five particularly confusing terms.

Apps - now used almost exclusively to describe mobile computing software. There are applications on your computer but apps on your phone or tablet - Photoshop (the application) on your iMac but Photoshop (the app) on your iPhone.  

To further the confusion, the apps on your Apple iPhone run on a different operating system (iOS) to the applications on your Apple computer (macOS)


MOOC - A MOOC is an online course with open enrolment and no fees - see here

Ping -
A ping ((Packet Internet Groper) is the time it takes for a small data set to be transmitted from your device to a server on the Internet and back to your device again. The ping time is measured in milliseconds (ms). . 

For those outside of IT that doesn't help much but essentially it helps  measures the speed of a webpage

SEO - search engine optimisation. SEO is the art of making your web page easier to find by the 'spiders' which crawl the web looking to recognise images and content visitors will be interested in. 

Each page has a ranking depending on the search term - the aim is to get as close to the top of the page as possible.


SSD - A solid state device.
An SSD is lighter and more reliable than traditional hard drive

In human English this  means that it does not have a hard drive with moveable parts - the Macbook Air is a good example. 

SSDs are lighter and - in theory - less prone to crashes caused by a mechanical malfunction. They can also load much faster
