DIFFERENCE BETWEEN LEGACY AND UEFI BIOS

LEGACY BIOS

LEGACY BIOS, OR BASIC INPUT/OUTPUT SYSTEM, IS A FIRMWARE INTERFACE THAT HAS BEEN USED IN PERSONAL COMPUTERS SINCE THE 1980S.

IT IS RESPONSIBLE FOR INITIALIZING THE HARDWARE AND LOADING THE OPERATING SYSTEM. LEGACY BIOS IS A 16-BIT SYSTEM,

WHICH MEANS THAT IT IS LIMITED IN ITS CAPABILITIES. FOR EXAMPLE, IT CAN ONLY SUPPORT HARD DRIVES UP TO 2.2 TERABYTES IN SIZE.

___________

UEFI

UEFI, OR UNIFIED EXTENSIBLE FIRMWARE INTERFACE, IS A NEWER FIRMWARE INTERFACE THAT WAS INTRODUCED IN 2005. IT IS DESIGNED TO REPLACE LEGACY BIOS AND OFFERS A NUMBER OF ADVANTAGES, INCLUDING:

FASTER BOOT TIMES

SUPPORT FOR LARGER HARD DRIVES (UP TO 9 ZETTABYTES)

A GRAPHICAL USER INTERFACE

SECURE BOOT SUPPORT

SUPPORT FOR NETWORK BOOTING

UEFI IS A 32-BIT OR 64-BIT SYSTEM, WHICH GIVES IT MORE FLEXIBILITY THAN LEGACY BIOS. IT ALSO SUPPORTS A WIDER RANGE OF HARDWARE, INCLUDING 64-BIT PROCESSORS AND UEFI-COMPATIBLE OPERATING SYSTEMS.

TCP/IP MODEL

HISTORY OF TCP/IP MODEL THE TCP/IP MODEL WAS DEVELOPED BY VINT CERF AND BOB KAHN IN THE 1970S. THEY WERE BOTH WORKING AT THE DEFENSE ADVANCED RESEARCH PROJECTS AGENCY (DARPA) AT THE TIME. Vint Cerf And Bob Kahn CERF AND KAHN WERE TASKED WITH DEVELOPING A NEW NETWORK PROTOCOL THAT WOULD BE MORE RELIABLE AND EFFICIENT THAN THE EXISTING PROTOCOLS. THEY CAME UP WITH THE IDEA OF USING A LAYERED APPROACH, WHICH WOULD ALLOW EACH LAYER TO FOCUS ON A SPECIFIC TASK. THIS LED TO THE DEVELOPMENT OF THE TCP/IP MODEL, WHICH IS STILL THE BASIS FOR HOW DATA IS TRANSMITTED OVER THE INTERNET TODAY. CERF AND KAHN ARE OFTEN REFERRED TO AS THE "FATHERS OF THE INTERNET" FOR THEIR WORK ON THE TCP/IP MODEL. THEY WERE INDUCTED INTO THE NATIONAL INVENTORS HALL OF FAME IN 2004 FOR THEIR CONTRIBUTIONS TO THE DEVELOPMENT OF THE INTERNET. HERE ARE SOME OTHER NOTABLE PEOPLE WHO CONTRIBUTED TO THE DEVELOPMENT OF THE TCP/IP MODEL: JON POSTEL: POSTEL WAS THE FIRST CHAIRMAN OF THE INTERNET ENGINEERI...
