This is incorrect. Justin's explanation is much more on point, although What you've got is built-in Intel Graphics Media Accelerator, or GMA, graphics is confusing. Think of Intel Graphics Media Accelerator as just another make and model of video card, similar to NVidia GeForce or ATI Radeon.
bacterium. pl. bacteria [L.] any prokaryotic microorganism. Bacteria are single-celled microorganisms that differ from all other organisms (the eukaryotes) in lacking a true nucleus and organelles such as mitochondria, chloroplasts and lysosomes.
Bacteria are living things that have only one cell. Under a microscope, they look like balls, rods, or spirals. They are so small that a line of 1,000 could fit across a pencil eraser. Most bacteria won't hurt you - less than 1 percent of the different types make people sick. Many are helpful.
