In dual-mode systems, only OS can access I/O devices, memory, and CPU in its “monitor” mode. Furthermore, the designer must make it difficult for an adversary to side-step the security mechanism; one of the simplest ways for an adversary to steal confidential information is to bribe someone on the inside. In most instances, a midrange computer is employed as a network server when there are a small to medium number of client systems. All modern computer motherboards contain BIOS software. The central processing unit (CPU) is responsible for calculating operations like physics, audio, netcode, positional data, and countless other systems in modern PC games. Computer has become an indispensable and multipurpose tool. It increased the CPU utilization. Modern computers can perform tasks such as word processing, web browsing and database management. It is the operating systems job to allow this to happen seamlessly. Your new computer will boot up and shut down faster than it would have with a BIOS, and you can use drives of 2.2 TB or more in size.
