a. Due to the ever-changing nature of two primary components, balancing performance across CPU, memory, buses, and peripheral devices is almost difficult. Identify these characteristics and analyze how their nature makes it difficult to maintain the balance of these devices. b. When the computer is used optimally, with many apps running, the CPU consumption is often just 37%, implying that the CPU remains idle for the majority of the time and hence wasteful. Discuss how employing at least two or more tasks will help the machine run more efficiently and decrease idle time.

Fundamentals of Input and Output Performance

The I/O subsystem is a component of computer system design that uses buses to assist communication between the Central Processing Unit, Computer Memory/Storage, and Input and Output Devices (that is known as peripheral devices). The I/O subsystem includes disc controllers, tape drives, discs, system buses, and other devices. The I/O database application reads and writes drives using the operating system windows I/O.
