Strength
Computers can calculate faster than humans can. They can do a lot of tasks at the same time and store a lot of information. They are precise and accurate. Computers are immune to fatigue and don't get tired, they can work for a long time without stopping.
Limitation
Computers are built and designed by humans, so they rely on humans. They lack the ability to decide on their own and need to be programmed first.
