Hardware Components and Types of Computer Systems

• Computer hardware devices should be selected based on their support for the information systems and organizational needs.
• The central processing unit (CPU) consists of the arithmetic/logic unit (ALU), control unit (CU), and registers.
• The CPU executes instructions through the instruction and execution phases, with instruction time (I-time) and execution time (E-time).
• Primary storage or main memory provides a working storage area for program instructions and data, and contains thousands of circuits imprinted on a silicon chip.
• Random access memory (RAM) is temporary and volatile, while read-only memory (ROM) is non-volatile and provides permanent storage for data and instructions that do not change.
• Secondary storage allows organizations to store large amounts of data and instructions more permanently than main memory, and includes sequential access and direct access storage devices.
• Input involves the conversion of human-readable data into machine-readable form through data entry and the transfer of machine-readable data into the system.
• Input devices include keyboards, mice, scanners, touch-sensitive screens, and point-of-sale and automated teller machines.
• Output devices include display monitors, printers, plotters, and digital audio players.
• Computer systems can be classified as handheld, smart phones, portable, thin client, desktop, workstation, server, mainframe, and supercomputer.
• Enterprise storage options include attached storage, network-attached storage (NAS), and storage area network (SAN).
• Multiprocessing involves the simultaneous execution of two or more instructions at the same time, while parallel computing involves the simultaneous execution of the same task on multiple processors to obtain results faster.
