1. Presentation
- All in one
A laptop (or notebook) is a computer whose main feature is its portability. Unlike a desktop computer, it has no CPU. A laptop is composed of several elements: the processor, the motherboard, the hard drive, a keyboard, a screen and a mouse.
- The prices vary
All these elements are packed inside a small box, hence the generally higher price of discount laptops as compare to desktop computers. Only mini laptops are available at lower prices.
- Lightness is a significant advantage
The average size of a notebook is 35 cm in width and 27 cm in depth and 25 cm by 17 cm in mini laptops. There are also large laptops which measure 40 cm in width and 30 cm in depth. Portable PCs usually weigh around 4 kg. The weight goes hand in hand with the size, so the smaller a computer, the more lightweight and easier to carry it is.
- Integrated parts
Most of the components are integrated, so they cannot be changed. Therefore, one should know the technical features of a laptop and what they intend to use it for before purchasing it. In addition to this, the integration of all parts by the manufacturer minimizes the risk of hardware incompatibilities.
- Autonomy
The advantage of a laptop is that it can also be used without being connected to the mains. It runs on a rechargeable battery.
2. Uses
The mobility and small dimensions of laptops facilitate their use. Originally limited to a strict and professional office use, the laptop has evolved into a full multimedia device. It can be used for photo editing, video games, DVDs, etc. Netbooks focus on the connection and mobility.
Communication pros can connect to wireless networks with their mobile phones in almost any area, provided that there is Wi-Fi or 3G coverage there. Small and lightweight, ultraportable netbooks allow users to chat on instant messaging services, check their e-mails, perform simple office tasks while at coffee, in a train or in a waiting room with Wi-Fi. Netbooks have also conquered the female audience as they can be easily slipped into a handbag.
Gamers and movie lovers can indulge their passions on a laptop with a comfortable screen (15 to 20 inches), a powerful graphics card and a powerful processor wherever they are.
Memory, computing power... Mobile professionals can use the same functions as on their desktop computers and install different pieces of software on a laptop equipped with a high-capacity hard drive and a powerful processor.
Video editing, photo processing, mixing sound... These multimedia applications can also run on laptops that combine a large storage capacity and speed. The number of inputs and outputs also allow a greater interactivity with high-tech accessories: USB2 ports, memory sticks, digital cameras, external hard drives...
It is particularly important to check the following characteristics when buying a laptop, in addition to the choice of the elements:
The operating temperature: The functioning of various elements of the laptop (including the processor) induces an increase in the temperature, which can be annoying at times (especially when the temperature keyboard is too high).
The noise: Laptops are often equipped with exhaust heat devices, such as fans, in order to dissipate the heat. This is also the case of the motors driving the rotating disks or hard drive/CD/DVD ROMs. Therefore, you should make inquiries on the noise level of the computer.
The warranty: A laptop is a big investment, so it is essential to be offered warranty. This warranty is even more important in laptops whose components cannot be interchanged (graphics card, sound card, etc.). Most offers include a de facto warranty of a few months to a year, but it may be wise to have an extended warranty certificate.
The software bundle: Laptops like discount Acer laptops are almost always equipped with an operating system, but some offers also include software such as office automation tools, an encyclopedia or an antivirus.
The protective cover: A carrying case is needed to protect and transport the accessories when the laptop is designed for portable use.
Moreover, one is strongly advised to invest in a security cable to attach the laptop to a stationary piece of furniture.
