The PC: Then and Now
To say the least, computers have changed immensely over the last 30 years. It's hard to comprehend the way technology has advanced during this time. The first PC computer was the IBM model 5150 invented in 1981 and held about 64kB of memory. The 11 inch screen showed text and images in one color, green. It costs around $3,005 dollars, 7,613 dollars today. Today's Lenovo ThinkCentre Edge 91z is about 1, 386 dollars and has a 21 inch screen. It shows everything in color and has built in speakers. The way IBM has advanced their computers has changed how everything works. Technology is now a necessity for all people and we are so fortunate to be able to use computers!
