Definition of Portable Computer

A portable computer, often referred to as a laptop or notebook, is a compact computing device designed for mobility. Unlike traditional desktop computers, portable computers are lightweight, slim, and equipped with a built-in display, keyboard, and trackpad or pointing device. They are powered by rechargeable batteries, allowing users to work or access information from virtually anywhere.

Origin of Portable Computer

The concept of portable computing dates back to the 1970s when early attempts were made to create compact computing devices. However, it wasn't until the 1980s that portable computers began to gain popularity with the introduction of the Osborne 1 and later the IBM PC Convertible. These early models were bulky and had limited functionality compared to modern laptops. Over the years, advancements in technology led to the development of smaller, more powerful portable computers, revolutionizing the way people work, communicate, and access information.

Practical Application of Portable Computer

One practical application of portable computers is in business settings. Professionals can use laptops to stay productive while on the go, whether attending meetings, traveling for work, or working remotely. Portable computers enable seamless access to email, documents, presentations, and other essential tools, ensuring continuity in workflow and collaboration regardless of location.
