A laptop is a portable, foldable personal computer with its time of autonomous operation, that is, temporarily independent of power; the composition of integrated components and input and output devices and rightly considered portable and mobile device.
Advantages and disadvantages of laptops over desktop PCs:
Light weight and dimensions. Laptops can quickly move laptops to another place. It can be taken on a business trip, another country, or on vacation. Moving a desktop computer to another room/office is often a problem, not to mention moving to another city.
It is not necessary to connect external devices to work. The laptop includes a built-in display, keyboard, and pointer (usually a touchpad), and all of these devices must be connected separately on the desktop computer.
Autonomous operation capability. The presence of the battery allows the laptop to work in conditions where the electrical network is unavailable (in the train, plane, car, cafe, and just outside). The desktop computer can run autonomously for brief periods and only if an uninterrupted power supply exists.
Capacity to connect to wireless networks. Almost all modern laptops (except some over-budget models) have a built-in Wi-Fi adapter that allows you to connect to the Internet without wires. In addition, Wi-Fi access points are available in many cafes, entertainment centers, airports, and hotels. Urban Wi-Fi networks also allow wireless connectivity in many parts of the city. Desktop computers usually do not contain a built-in Wi-Fi adapter (except for some expensive models); however, this drawback is insignificant for desktop computers.
In sum, all the advantages of laptops over desktop computers are the essential quality of laptops – mobility.
