Computer Organization And Architecture Carl Hamacher Ebook Download
In electronics engineering and computer engineering, computer architecture is a set of disciplines that describes a computer system by specifying its parts and their relations. For example, at a high level, computer architecture may be concerned with how the central processing unit (CPU) acts and how it uses computer memory.
The term computer architecture refers to the physical arrangement, organization, and interconnections of the system’s components in the particular system configuration bottom to top. A common configuration has a central processing unit executing instructions, a dedicated memory unit, and memory resources shared between the CPU and memory. The architecture is also specified by the nature and arrangement of the system’s various components, including the electronic, electromechanical, and software parts.
The concept of hardware is a relatively simple one. It is the “hard” part of computers which does the actual processing. The hardware can be considered as a specialized type of electronic, electromechanical or mechanical device. A computer can be considered as a specialized type of mechanical device, a specialized type of electronic circuitry or as a specialized type of circuitry. This type of device is known as a computing device. The basic components of a basic computing device which perform the operations on the data can be considered as a very simple electronic circuitry and a specific type of processor and memory suitable for performing the operating system functions.
Off-line terminals are hardware devices that perform computer operating system functions on your computer in a manner different from your usual work process. You use these terminals in a similar way to using an ordinary keyboard and mouse to interact with a computer. You type on the keyboard, and the camera receives the input. You click the mouse, and the video display shows the corresponding pointer moving. The menus in the operating system are displayed on your display, and you click to select your options.
