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.

However, They Differ in How They Achieve This: Dos Attack: Imagine A Single Person Throwing Rocks at A Castle Gate. A This Person Represents the Attacker, And the Rocks Represent the Malicious Traffic. The Castle Gate Represents the Target System or Network Resource. The Attacker Keeps Throwing Rocks, Trying to Overwhelm the Gate's Defenses and Gain Entry. Dos Attacks Are Typically Launched from A Single System. They Can Be Effective Against Small Systems or Networks, But Larger Systems Can Often Withstand Them. DDos Attack: Imagine An Army Throwing Rocks at A Castle Gate. This Army Represents the Attacker, And the Rocks Represent the Malicious Traffic. The Castle Gate Represents the Target System or Network Resource. The Attackers Coordinate Their Attack, Throwing Rocks from Multiple Directions at Once. ...
