Oz is a special type of computer language that helps people write computer programs. It is like a special language that is used by people who work with computers a lot. Think of it like a secret code that only computer experts can read and understand.
When people use Oz, they use special sentences or commands that tell the computer what to do. Just like you might use special words when talking to a friend, like "hello" or "goodbye," people who use Oz use special words or commands to talk to a computer.
One thing that makes Oz different from other computer languages is that it is based on the idea of programming with constraints. Constraints are rules or limitations that a program has to follow in order to work correctly. So, when people use Oz, they have to make sure that their program follows all the rules and limitations that they set.
For example, if you were making a program that had to count how many apples were in a basket, you might set some constraints like "only count apples that are red or green" or "don't count any apples that are smaller than a golf ball." These rules help make sure that your program works correctly and gives you the right answer.
Overall, Oz is a special language that computer experts use to program computers. It is based on the idea of using constraints to make sure that programs work correctly, and it uses special sentences or commands to communicate with computers.
