The computers that we buy, let them be laptops or PCs or any other portable device that has display function has graphic cards, and if they are not custom built then chances are that they already have ‘Integrated Graphics Card’. It means that they are standard graphic cards which are integrated by default on computer’s motherboard and their function is to display standard images on screen.
They are also known as ‘Onboard Graphics Card’, as they can be upgraded but they need plugging of new graphics card onto your computer’s motherboard which makes computer to ignore previous version of obsolete type. They are the least powerful variety in all of graphic cards and today they are considered outdated as thanks to latest technology more powerful variants exist. All the latest high end games use advanced versions, so if you seek to run modern applications on them, your integrated type will fail you.
