Laptop It is a laptop or laptop is a mobile personal computer, its weight is usually between 1 and 3 Kg.
These are capable of performing most of the tasks that desktop computers perform.
The Advantage is that they are smaller, lighter, and can operate for a specified period without being connected to electricity.
What are the Components of a Laptop?
The components of a laptop are related to the components of desktop computers. But are typically smaller in size, with similar components, some of which are listed below:
- Low power CPU
- 5-inch or smaller hard drive
- RAM Memory Modules SO DIMM (Small Outline DIMM)
- Small format CD or DVD reader and writer unit
- Integrated keyboard
- Integrated TFT, WXGA, or OLED screen that in turn performs the function of the laptop’s lid and f
- facilitates its mobility
- Touchpad or trackpad touchpad to operate the pointer instead of the mouse
- Charger (can be charged in use, to optimize time and energy)
- Battery, typically 2 to 4 hours long.
What are the Features of Laptops?
They work using a battery or an adapter that allows both are charging the battery and supplying power. It has a small battery that allows you to keep the clock and other data in a power failure.
They usually have an LCD screen and a touchpad. In general, they have a PC Card (formerly PCMCIA) or ExpressCard for expansion cards.
There is a type of notebook called netbooks, which are smaller and lighter, M 570E
There is no industry-standard form factor for notebooks, meaning each manufacturer has its design and construction style.
It increases the components’ prices if they have to be replaced or repaired, making them more challenging to obtain.
There are often even incompatibilities between components of notebooks from the same manufacturer.
What are the Brands of Laptop?
Many brands, including major ones, do not design and manufacture their laptops.
As an alternative, several original design manufacturers (ODMs) design the new laptop models, and brands choose which models to include in their lineup.
In 2006, seven major ODMs manufactured 7 out of 10 laptops globally, with the largest (Quanta Computer) having 30% global market share.
Therefore, identical models are often available to both a multinational and a low-profile, locally-branded ODM company.
The massive majority of manufacturing laptops on the market by a handful of original design manufacturers (ODMs). The most important are:
- Quanta sells to (amongst others) HP / Compaq, Dell, Toshiba, Sony, Fujitsu, Acer, NEC, Gateway, and Lenovo / IBM – note that Quanta is currently (as of August 2007) the largest manufacturer of laptops in the world
- Compal sells to Toshiba, HP / Compaq, Acer, and Dell.
- Wistron Corporation (Acer’s manufacturing and former design division) sells to HP / Compaq, Dell, IBM, NEC, Acer, Lenovo, and IBM /.
- Flextronics (formerly Arima Computing Corporation notebook division) sells to HP / Compaq, NEC, and Dell.
- ECS sells to IBM, Fujitsu and Dell.
- Asus sells to Apple (iBook), Sony, and Samsung.
- Inventec sells to HP / Compaq, Toshiba, and BenQ.
- Uniwill sells to Lenovo / IBM and Fujitsu, and PC World UK own Advent brand
What is the Advantage of a Laptop?
Their great Advantage lies in the mobility they allow since it is possible to take them wherever you want.
Laptops can also perform the same functions as any other computer and consume less power and are quieter.
Possible risks of Laptop?
Working with the laptop on the lap can cause sterility in men, it becomes very hot, if the time of use prolongs. In vitro studies show that putting the laptop on the lap while it is connected to the Internet could cause damage to the sperm at various levels since they emit minimal electromagnetic wave radiation and the fact of connecting it to Wi-Fi increases between 5 and 6 times this radiation.
Sperm are produced in the Testicles and these are outside the body to maintain a lower temperature than the rest of the body, as the cells responsible for giving rise to sperm do not work well at high temperatures. They are very sensitive to temperature. That is, the function of the testicles can be affected by the excessive heat generated. Only the production of sperm is affected, but not in the production of male hormones, that is, you will not look more feminine or anything strange, only your fertility will be affected.
The heat generated by laptops can cause skin blemishes, a condition called “burnt skin syndrome.” This syndrome was apparently popular with people gathering around fires or heaters to warm themselves, and now it has come back with technology.
One possible solution is to place a thick pillow on the legs and place the laptop on top, this reduces heat transmission and therefore reduces the risk of sterility. Although it is best to use a desk.
