These notebooks have replaced the I and therefore a little bulkier laptops. The notebook model features a power such as a computer, it has a built-in keyboard, internal hard drive and BluRay drive, speakers and a screen that usually come TFT LCD or OLED screens with a size of 12 “or 17” to use.

The LCD display from NetBook models have a size of 10 “to 13”, which are big enough to work. Notebooks were equipped with powerful, developed specifically for use on mobile units (CPU). That can Central processing units with more efficient power consumption be as ULV processors, dual core processors or even quad-core processors like the core i7, Intel or the FX 8320 from AMD. Other laptops work with Pentium or the Celeron from Intel, other Ultrabooks Phenom, Turion or Athlon from AMD. The stroke units of the units lie in the range of 2 GHz and 2 GHz, which values for the thermal design power (TDP) range from some a few Watts up to over 100 W, which for the computing power ranging from 4,500 to over 125,000 Dhrystone MIPS (DMIPS). Using notebook Web pages, you can get a precision notebook test. Apart from the high-performance central processing units with more or less large caches, large amounts of memory with DDR system and memory of 8 GB and more facilities, also hundreds GB and more internal hard drives and a drive. Of connections they are equipped typically with several USB ports, FireWire, multimedia card readers and different with other compounds such as the HDMI connection.
