If everyone knows the role of the BIOS, the most freaks Computer can they have never learned about the UEFI despite the fact that Apple has put forward several years ago on their computers but with devices the PC remains the integration of the Unified Extensible Firmware Interface and Taweidaha Balbius is still new!
But before you know you Pmaho the UEFI First, let me remind you the role of the BIOS BIOS.
The BIOS, a shortcut for Basic input output system is a memory Mitte meaning it can not be registered, and delete data in it, as is the case of the Ram RAM where it can be a computer that records the data and deletes the other, Valbius is an IC-class 16-bit is available on a 1 megabyte RAM, the controlling all the pieces of hardware in the computer from which to prepare these pieces through permeated the settings that appear when you start the computer (see photo) is also considered the BIOS of the most important components of the motherboard in the computer as it is the first piece in a computer operates when you click on the start button Computer they make sure that all the pieces of other computer-related work, as you read their settings ... before allowing the transition from the development of read only memory to develop the random access memory where it appears Lugo laborer system, through reading the information in the MBR of the hard disk party to the BIOS so that you can select from any section in the hard disk where the operating system resides.
Well now Vhenma role of the BIOS Ntql now know on the UEFI and BIOS, which is successor.
With technological development that the right pieces of hardware, and the fact that it was I became working on data processing more than its predecessor, as treatments 32 and 64-bit, the BIOS extent of processing up to 16-bit has become impossible to keep pace with the BIOS of this technological development, as some security gaps in the BIOS and that makes the latter easy Altjoaz through the use of some of the tools the bootkit, which makes the hacker's easy to enter the operating system despite Bbasord well as protect the BIOS. Make of this technique technological development covers the needs of real users in the field of speed as well as protection.
One of the main differences between the bios and the first permeated UEFI settings, if some companies are keen to be the only form permeated the BIOS settings for the UEFI Mokhtfatta some other companies offer very different settings permeated permeated the BIOS settings.
Hard drives and quit.
First, the BIOS is confined to recognize the hard drives with an area not to exceed 2.2 Tarabet This means that the hard drives that exceed this space can not be of Pius identify them, but for the UEFI he is able to recognize the hard drives that reach the area to the limits of 9.4 zettabyte any 1024 GB Amadorbh in 3 1024GB X 1024 GB X 1024 GB !!! This is a very large number also noted.
As the BIOS, it supports the MBR latter who accepts the hard drive partition to 4 units partition (you can not divide the hard disk to more than 4 units) either with the UEFI that rely on (GUID Partition Table (GPT they could accept partition your hard drive to a number theoretically infinite, either Mkrosvet they confine this figure at 128. otherwise have been improved possibilities boot (boot) significantly either from the network or from a hard drive.
Significant support for modern devices that run on 64bit Firmware
This means that the UEFI can support the use of a large amount of Ram for the most complex processors can also support limits to 17.2 billion Jagabit of Ram in boot Windows boot making Windows more quickly be turned on your TV!
Secure boot feature
Where protection has been improved by quitting some systems that Astalh them to secure boot, which can be exceeded by which protection is also quitting the secure boot feature comes nicest They protect you from viruses and malicious software targeting Windows
