How Computers Work: What Makes a Computer, a Computer?
Introduction to Computers
- May-Li Khoe introduces herself as a designer and inventor, highlighting her experience at Apple and current focus on designing educational products for children.
- Nat, an original Xbox designer, shares his long history with computers and current work in virtual reality.
The Evolution of Tools
- Humans have historically created tools (e.g., wheelbarrows, hammers) to solve problems; the quest for machines that can assist with cognitive tasks began as well.
- Early machines were designed not just for physical manipulation but to handle information processing.
Core Functions of Computers
- To be classified as a computer, a machine must perform four essential tasks: take input, store information, process it, and output results.
- The earliest computers utilized wood and metal components; by the 20th century, they transitioned to electrical components but remained large and slow.
From Basic Calculators to Modern Devices
- Initial computers functioned primarily as calculators manipulating numbers; modern capabilities include communication, gaming, robotics control, etc.
- Despite advancements in design and functionality over time, all computers still adhere to the foundational four functions.
Understanding Input
- Input refers to how users or the environment provide data to the computer through various means like keyboards, mice, microphones, cameras or touch screens.
Storage & Processing Mechanisms
- Information from inputs is stored in memory; processors manipulate this data using algorithms before sending it back for further storage until ready for output.
Output Capabilities of Computers
- Output varies based on design—computers can display text/images/videos or send signals to control devices. Internet connectivity allows outputs from one computer to serve as inputs for another.
