The document discusses the components of a management information system (MIS), focusing on hardware. It defines hardware as the physical components of a computer system, including processing equipment and peripheral devices. It notes that hardware supports organizational goals and objectives. Advantages of investing in computer hardware for organizations include improving productivity, increasing revenue, reducing costs, and enabling collaboration. The document outlines different types of hardware components such as the central processing unit (CPU), primary and secondary storage, and different classifications of computers including mainframes, servers, and minicomputers. It also discusses managing hardware and software assets.

- 1. Mr . Sathish Kumar . M Department of Electronics and Communication Engineering I’ve learned that people will forget what you said, people will forget what you did, but people will never forget how you made them feel. –Maya Angelou
- 2. System Hardware In Management Information System MIS Management Information System
- 3. Structure of MIS may be understood by looking at the physical components of the information system in an organization. • Hardware • Software • Database • Input & Output Hardware refers the physical data processing equipment and peripheral devices. Software is broad term given to the instruction or program that direct the operation of the hardware. the data base consist of all data utilized by application software. various physical input and output from the information system, existing in the form like printout, report etc.

- 5. What is hardware….. ? Hardware refers to the physical components of a computer and devices that perform the input, processing, storage, and output activities of the computer. Hardware can support objective of the information system, and goal of organization.
- 6. Advantages of hardware in Organization Organization invest in computer hardware to improve worker productivity, increase revenue, reduce cost, and provide better customer service, Speed up time-to-market, and enable collaboration among employees.
- 7. Bit • Binary digit • Represents smallest unit of data in the form of either 0 or 1 Byte • String of bits, usually eight • Stores one number or character The Computer System
- 8. Central Processing Unit (CPU) • Manipulates symbols, numbers, and letters • Controls other parts of the computer system The CPU and Primary Storage Primary Storage • Temporarily stores program instructions • Data being used by the instructions

- 10. Processing and Memory Devices Main memory provides temporary working storages area for programs and data. It is measured in byte.
- 11. Processing and Memory Devices Type of memory: • RAM (Random Access Memory) -> store data and instruction temporarily • ROM (Read Only Memory) -> instruction and data are stored permanently • Cache Memory -> a type of high-speed memory that CPU can access more rapidly than main memory.
- 13. Secondary Storage • Store a large amount of data and instruction safely and effectively. Access Methods • Data and information access can be sequential or direct. • Sequential Access data must be accessed in the order in which it is stored. • Direct Access data can be accessed directly. Without the need to pass by other data in sequences.
- 15. Mainframes Largest computer, massive memory, rapid processing power Midrange computers Less powerful, less expensive, and smaller than a mainframe Server Provides software and other resources to computers over a network
- 16. Minicomputers Middle-range computer, used in universities, factories, or research laboratories Server Farm Large group of servers maintained by a commercial vendor, available for electronic commerce and other activities
- 17. Managing Hardware & Software Assets • Capacity planning: Process of predicting the computing power • Scalability: Ability of a computer, product, or system to expand and to serve without breaking down • Designates the total cost of owning technology resources • Includes initial purchase costs, cost of hardware and software upgrades, maintenance, technical support, and training
