§1. The objects around us

Grade 5 Computer Science topic: '§1. The objects around us' (pp. 6–11, T. R. Oruskulov, M. U. Kasymaliev, A. A. Kuznetsov, L. L. Bosova). An object is any part of the surrounding reality (a thing, a process, a phenomenon) that a person takes in as a single whole. A telephone, a table, a book, a cat are examples of objects that are things. A set is a collection, a group of objects; the objects that make up a set are called its elements. A set can be finite (for example, the set of digits) or infinite (for example, the set of natural numbers). Every object has a name of its own, which may be a common name or a proper name. Computer science is the science that studies the laws of the processes of passing on, storing and processing information in nature, in society and in technology. Every property is defined by some quantity and the value it takes. What an object can do is shown by the names of the actions that answer the questions 'What can it do?' (an active action) or 'What can be done with it?' (a passive action).
