One of the first portable computers was the Portal R2E CCMC. Since then (1980), computers, and laptops specifically, have improved and have become better. The laptop in the 3D model is the average design of a modern laptop, which has improved drastically since the release of the first portable computers in the 1980s. The portable computer (later known as a laptop because of its ability to be positioned in a person's lap) has spawned a considerable industry. Some of the companies which make laptops in the modern world are HP, Acer, Lenovo, Apple, Alienware and Fujitsu. Most laptops in the world of today use 3 main operating systems (OS) which are Windows, iOS and Linux, although the first two are better known among the common person. The OS is simply the system which a computer uses in order to perform its tasks. It can be thought somewhat as the pillars of the software in a computer. Desktops and OS were not changed much as a result of laptops, as it only meant a different segment of the industry was born. However, laptops did help research to advance, specifically in nano-technology and quantum physics, to tackle the problem of making computer parts the smallest possible size with the parts continuing to work. This research has led to the overall size of computer parts, and therefore computers as a whole, shrinking, both desktops and laptops alike. The Osborne 1, released in 1981 by Osborne Computer. This is considered to be the first truly portable computer, one year later than the Portal R2E CCMC, which can also be considered the first. Regardless of this, the Osborne 1 incorporated some new technology such as the now very common opening/closing system of a laptop and also a screen and keyboard in different sections of the computer, although the screen was a hurtful five inch. The Osborne also had two floppy drives available for use. Laptops have become better in many ways to previous versions years ago. There are also many types of laptop. For example, there are gaming laptops such as the ones created by Alienware and Acer. There are laptops which are extra light and flexible like the ones made by Lenovo and Microsoft. There are laptops with iOS which serve for better creative creation and are very light, such as the Macbook pro or air. These advances in technology and diversity make laptops as capable as desktops with a little less power but allowing the carrying of the computer for travelling long and short distances. The general design of a modern laptop is very simple, as most laptops today have a similar chassis but different on the outside and outside. The general template or build is to have two main parts of the computer that can be 'folded'. The main part is where the keyboard is and where the housing for all of the software is underneath. The second part is the screen and the connection between the display and the software that makes the display. In simple terms, the screen acts as a way of displaying what the program is doing, and it shows this in a way humans can understand (transforms computer data(the 0s and 1s) into visual data).
