List three examples of deadlocks that are not related to a computer-system environment

Traffic Gridlock: This is a common example of a deadlock that occurs in real life. When four cars come to a four-way stop at the same time and each one is waiting for the other to move first, none of the cars can move. This is because each car is waiting for the other to move first, creating a circular wait.

Business Negotiations: Deadlocks can also occur in business negotiations. For example, two companies may be negotiating a merger. Company A won't agree to the merger unless Company B agrees to certain terms. However, Company B won't agree to those terms unless Company A agrees to some other terms. This creates a deadlock because neither company is willing to budge.

Legislative Deadlock: This can occur when two legislative bodies or more cannot agree on a piece of legislation. For example, the House of Representatives may pass a bill, but the Senate may not agree with it. Until both bodies can agree on the same bill, the legislation is in a deadlock.
