Computer law in general addresses issues such as privacy, defamation, freedom of speech, the role of cryptography, and intellectual property rights. We have room here only to touch on the last topic. Protecting computer-related technology may require a combination of patents, trade secrets, and copyrights. Additionally, trademarks are an important component in marketing such technology and protecting market share.
Computers are different things to different people.
To a hardware engineer, a computer is a collection of controllers, buses, timing protocols, and such. To a computer salesperson, the computer has characteristics such as price, bundled software, and availability. Everyone can learn by looking at the computer through someone else's eyes. A programmer who doesn't understand the hardware will never fully master interrupt handlers. A project manager who does not appreciate the trade-offs between memory requirements, execution speed, and development effort will never be able to accurately translate customer desires into engineering tasks.
