Electronics is the science of controlling electrical energy electrically, in which the electrons have a fundamental role.

Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes, integrated circuits, associated passive electrical components, and interconnection technologies.

Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit.

A computer is a device that can be instructed to carry out an arbitrary set of arithmetic or logical operations automatically.

The ability of computers to follow a sequence of operations, called a program, make computers very applicable to a wide range of tasks.

Such computers are used as control systems for a very wide variety of industrial and consumer devices.

This includes simple special purpose devices like microwave ovens and remote controls, factory devices such as industrial robots and computer assisted design, but also in general purpose devices like personal computers and mobile devices such as smartphones.

The Internet is run on computers and it connects millions of other computers.

Office supplies are consumables and equipment regularly used in offices by businesses and other organizations, by individuals engaged in written communications, recordkeeping or bookkeeping, janitorial and cleaning, and for storage of supplies or data.

The range of items classified as office supplies varies, and typically includes small, expendable, daily use items, consumable products, small machines, higher cost equipment such as computers, as well as office furniture.

A laptop, often called a notebook or "notebook computer", is a small, portable with a "clamshell" form factor, an alphanumeric keyboard on the lower part of the "clamshell" and a thin LCD or LED computer screen on the upper portion, which is opened up to use the computer.

Laptops are folded shut for transportation, and thus are suitable for mobile use.

Although originally there was a distinction between laptops and notebooks, the former being bigger and heavier than the latter, as of 2014, there is often no longer any difference.

Laptops are commonly used in a variety of settings, such as at work, in education, Internet surfing using sites such as YouTube and for personal multimedia and home computer use.
