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.

Question

Operating systems protect the computer hardware and its components. They also perform many responsibilities and/or provide services to manage various resources of the computer system as well as promote the efficiency of use of the computer systems.
(i). In your own words, distinguish between user-
visible registers and control and status registers in the context of computer systems and embedded systems used in organizations; and draw a table of comparison to illustrate your answer.
(ii). Identify two examples of each the above categories of registers and explain, in your own words, the functions that each of them performs in a computer system.

Software system that manages computer hardware, software resources, and provide common services for computer programs.

Modern computers are based on a stored-program concept introduced by John Von Neumann (also famously referred to as the Von Neumann Architecture). You are, therefore, expected been studied during class, said architecture, and provide an overview of the Von Neumann Architecture Please note that to answer this question, you are expected to illustrate the role of: Input devices along with relevant examples. Memory along with its types (i.e., both volatile and non-volatile).
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.

Digital memory comes in a variety of forms, including cache memory, random access memory (RAM), solid state drives (SSD), and hard disk drives (HDD). Computers include every one of them. Is it preferable for consumers to have only one memory standard, such as the many SSD sizes, or is there a value to having several standards? Is having many standards advantageous? Would things be simpler and less expensive for consumers if there was just one standard to follow?
a. Due to the constantly changing nature of two primary components, balancing performance across CPU, memory, buses, and peripheral devices is nearly difficult. Identify these characteristics and analyse how their nature makes it difficult to maintain the balance of these devices. b. During an ideal use of the computer, where many applications are running, the CPU consumption would typically be just 37 percent, indicating that the CPU is idle most of the time and hence wasteful. Discuss, using at least two or more jobs, how Interrupts might help enhance machine efficiency and minimise idle periods.
