Computers are machines that can store and execute programs to manipulate data. They are versatile and can perform the same tasks given enough time and storage, from mobile phones to supercomputers. Computers are now essential in daily life for information gathering, personal records, office work, and connecting with others. Robotic dogs with computer programs can help seniors who are lonely or sick by providing company and understanding feelings through cameras. The future of computers involves continued development of robot technology to perform dangerous tasks like spaceflight and search and rescue, enhancing lives at a lower cost than current robots.
