what is laptop computer
|
A laptop computer, or simply laptop (also notebook computer, notebook and notepad) is a small mobile computer, typically weighing 3-12 pounds (around 1.3 to 5.4 kilograms), although older laptops may weigh more. Laptops or notebook computers contain similar components to their desktop computer counterparts and perform the same functions.
Although laptop computers may provide greater Internet access and are more portable, they tend to be more expensive than desktop equivalents. Laptops or notebook computers are typically less powerful. They usually run on a single main battery or from an external AC/DC adapter that charges the battery while also supplying power to the computer itself. Laptops also tend to lag behind desktops in terms of upgradeability and features. Many computers also have a 3 volt cell to run the clock and other processes in the event of a power failure.
Most laptops have connectors for external monitors and keyboards, transforming them into desktop computers. Laptops can connect to networks using cables or via wireless connections. Wireless Internet access is possible because some laptops have built-in wireless adapters that allow connection to available wireless networks. Laptops contain components that are similar to their desktop counterparts and perform the same functions, but are miniaturized and optimized for mobile use and efficient power consumption, although typically less powerful for the same price.
Laptops typically have features such as a space for PC cards, an internal modem, a wireless card and ethernet port. They also have headphone jacks so that you can quietly listen to music and a CD or DVD ROM drive to play discs If you travel often and carry a lot of heavy belongings already, you will want to purchase a laptop which is very lightweight. If you travel less frequently, or have fewer concerns about heavy luggage, a larger laptop with more power and an easier to read large screen is a good choice. Many devices are designed to connect to Universal Serial Bus (USB) ports in your laptop, so you may want several to connect multiple peripheral devices..
When buying a laptop, it is important to think about what operating system you wish to install. Buying laptops online is also possible nowadays and you can decide on what specifications you want and have it built a certain way. When buying a laptop you may choose to get an extended warranty plan in case accidents happen.
