Laptop, Notebook and Netbok

Laptop are mobile computers that are relatively small and lightweight, weighing ranges from 1-6 kg, depending on size, materials, and specifications of the laptop. Resources derived from a battery or laptop adapter A / C that can be used to recharge the battery. Laptop batteries generally last about 1 to 6 hours before being discharged, depending on how the use of, specifications, and the size of the battery. Laptops are sometimes referred to as a notebook or a notebook computer only.

As personal computers, laptops have the same functionality with desktop computers (desktop computers) in general. Components contained in it are exactly the components on the desktop, only smaller and more numerous, become lighter, less heat and more power efficient.
Most laptops use LCD (Liquid Crystal Display) measuring 10 inches to 17 inches depending on the size of the laptop itself. In addition, the keyboard found on the free laptop is also sometimes equipped with a touch board that serves as a "substitute" the mouse. Additional keyboard and mouse can be attached via the Universal Serial Bus connector and PS / 2 if available.
In contrast to desktop computers, laptops have supporting components that are designed specifically to accommodate the portable nature of laptops. The main properties owned by the components of a laptop is its small size, low energy consumption, and efficient.



The types of laptop

Netbook
Netbook laptops refers to species that have certain specifications.  A netbook generally uses Intel's Atom processor.  This type of portable computers are small, usually with screens under 12 inches and weighs approximately 1 kg.
Asus netbooks became popular when it released a product called the Eee PC. At that time, computers at cheap prices is using the hard drive portable storage media like a USB Flash Disk (UFD), with a low capacity of 4GB.

Mainstream
This laptop, has a characteristic that is:> The processor used, such as Intel Core i5, i3, and Core 2 Duo.  At least 2GB of memory. > Have a drive to read and write DVDs.  Full-sized keyboard, or at least 80% of the width itself.

Tablet PC
This device has a touch screen that is easy to play, and easy to carry anywhere.
From 2010, these devices become a new trend. This trend is led by Apple Inc.. iPad presenting to the market. However, there is a difference between a Tablet PC and the iPad, namely: Tablet PC using the stylus is used. IPad while using the fingers.  Tablet PC intended to be a different laptop. While the iPad is intended as a gadget.

Computer

Said the computer was originally used to describe people whose jobs do arithmetic calculations, with or without a walker, but the word is then transferred to the machine itself. ENIAC, the U.S. early computers originally designed to take into account ballistics tables for weapons (artillery), calculate the density of neutron cross-section to see if a hydrogen bomb would work properly (this calculation, conducted in December 1945 until January 1946 and involved dala in more than one million punch cards, and then show the form under consideration would fail). CSIR Mk 1/CSIRAC, Australia's first computer, evaluated rainfall patterns for the catchment of the Snowy Mountains, a large Hydroelectric generation projects. It is also used in cryptanalysis, for example, the first digital electronic computer, Colossus, built during World War II. However, early visionaries also think that it will allow programming to play chess, moving images and other uses

Invention of the microprocessor in the 1970s, became possible to produce a very low-cost computers. PCs are becoming popular for many tasks, including keeping books, writing and printing documents. The calculation of forecasts and other repetitive math with lembatang scatter, related to e-mail and, the Internet. However, the widespread availability of computers and easy customization has seen them used for many other purposes. Simultaneously, a small computer, usually by adjusting the programming, started finding their way into other devices such as home appliances, automobiles, airplanes, and industrial equipment. Embedded processors which are controlled behavior of such devices easier, allowing more complex control behavior (for events, development of anti-lock brakes in cars). When the twenty-first century begins, most electrical devices, most forms of powered transport, and most factory production lines are controlled by computers.

People in government and large companies also use computers to automate the data collection and many tasks previously done by humans - for example, maintain and update accounts and inventory. In the field of education, scientists in various fields began using computers for their own analysis. Decline in computer prices to make them can be used by smaller organizations. Businesses, organizations, and governments often use very many small computers to complete tasks that were once performed by main frame computers are expensive and bulky.
