Study Notes
Hardware and Software in Business
- Managers should understand the characteristics of input, output, and storage devices to select the correct equipment for a business application.
- Understanding computers helps managers identify opportunities to improve business processes and potential applications.
- Common business applications like word processing and spreadsheet software require an understanding of factors involved in selecting them.
- Familiarity with software applications and recent developments like XML helps managers develop long-term technology plans.
Computer System Components
- A computer system consists of interrelated hardware and software components that work together to convert data into information.
- Hardware components include input devices, memory, central processing unit (CPU), output devices, and storage devices.
Basic Hardware Components
- Input devices enter data, information, or instructions into a computer-based information system.
- The central processing unit (CPU) controls a computer's main functions and enables users to execute programs or process data.
- Memory temporarily stores data awaiting processing, instructions, or processed data.
- Storage devices permanently store data and programs until needed.
- Output devices translate processed data into a human-readable form.
Cost-Efficient Forms of PCs
- Net PCs are low-cost, centrally managed computers that support network applications, but without disk drives, CD-ROM drives, or expansion slots.
- Thin clients rely on central servers for processing, providing applications and reducing memory and processor demands.
- Total Cost of Ownership (TCO) includes purchase/leasing costs and support services for end-users.
Input Devices
- Common input devices include keyboards, mice, and touchscreens.
- Optical character recognition (OCR) software recognizes individual characters from digital images.
- Optical mark recognition (OMR) detects and recognizes marks on paper forms.
- Bar code readers identify unique identification numbers from reflected light beams.
- Touchscreens allow users to make selections and control programs by pressing on the screen.
- Voice recognition enables control of computer programs or data entry through spoken commands via a microphone.
