- - - - Microprocessor [Chip/Processor/ CPU]
        Microscopic electronic components on a single integrated circuit that processes information according to software instructions.
      - CPU Speed Fast/Slow?
      - The Bit [binary digit]
        1’s and 0’s that allow us to represent, store, and manipulate data
      - Storage device
        Computer hardware that records and/or retrieves items to and from storage media.
        
        Reading
        Transferring items from a storage medium into memory.
        
        Writing
        Transferring items from a memory to a storage medium.
        
        Secondary Storage
        Store data more permanently without the need for electricity.
        
        Storage Media Type
        Magnetic storage
        Devices use the magnetic properties of iron oxide particles to store bits and bytes more permanently than RAM.
        Optical storage media
        Store bits using an optical laser to burn pits into the surface of a highly reflective surface.
        Solid State storage
        Devices use flash memory to store bits.
        
        System storage
        Used by a computer system for standard operations.

        ROM
        CMOS
        
        Flash memory card
        Chip that, unlike RAM, is nonvolatile and keeps its memory without the need for electricity.
        
        USB Flash Drives
        Use flash memory to provide high capacity storage through the USB port.
      - Input device [Touchscreen, Gamepad]
        Allows capturing and entering raw data into the computer system.
        Output device [LCD, Sound System]
        Allows you to observe the results of computer processing with one or more of your senses
      - Software
        System Software
        Controls the hardware, runs the computer system, operating system, disk management tools.
        
        Application Software
        Programs written to perform tasks, provides services for people, word processor, spreadsheets, database, media players and games
        
        System Software
        Interact with the computer hardware and application software programs, creating a layer of insulation between the two
        
        Operation Software
        A set of computer programs that runs or controls the computer hardware
        
        Application Software
        Groups and organizations use application software to help people make better decisions, improve service, or increase revenue.
        
        Productivity Software
        Word Processing,Spreadsheet,Presentation,Database,Personal Information Management]

        Electronic Data Interchange [EDI]
        Uses private communications networks
        called value-added networks (vans) to
        transmit standardized transaction between
        partners and suppliers.
        
        Transaction
        Processing
        System (TPS)
        An information
        system that
        supports and
        records
        transactions.
        
        Data collected in Transaction
        Processing Systems feeds into more
        sophisticated Management
        Information Systems (MIS) to provide
        useful information
        
        Two methods of processing transactions:
        Batch Processing
        Online Transaction Processing
        
        Batch Processing
        Transactions are collected over time and processed
        together in batches
        Online Transaction Processing
        Processing takes place at the point of the sale
