Study Notes
Virtual Reality (VR)
- Creates a computer-generated 3D environment that blocks out the physical world
- Users wear headsets and devices like gloves and vests to interact
- Applications include gaming, education, military training
Augmented Reality (AR)
- Overlays digital content onto the real world
- Provides contextually relevant information
- Examples include Snapchat filters, IKEA Place, Pokémon GO
Computer System Types
- Single-User Computers:
- Portable: Wearable computers, smartphones, laptops, tablets
- Non-Portable (Stationary): Desktop computers
- Multiple-User Computers: Servers, Mainframes, Supercomputers
Read-Only Memory (ROM)
- Provides permanent storage for data and instructions, it is nonvolatile
- Stores essential programming for computer startup
- Used in gaming system cartridges (e.g., Gameboy)
Secondary Data Storage Devices
- Store large amounts of data and programs more permanently than memory
- Offer advantages over memory: non-volatility, greater capacity, cheaper cost
- Not directly accessible by the CPU, data is transferred to primary storage first
- Common forms: magnetic (hard disk drives), optical (CD, DVD, Blu-ray), solid state (SSD, USB)
Magnetic Secondary Storage Devices
- Magnetic Tape:
- Sequential secondary storage medium
- Mainly for backups and archives
- Advantages: lower cost per gigabyte, longer lifespan (10-20 years)
Storage as a Service (Cloud Storage)
- Remotely hosted storage accessed over the internet
- Data storage service providers rent space to individuals and organizations
- Convenient and scalable option for businesses
- Services: Apple iCloud, Dropbox, Google Drive, Microsoft OneDrive (consumers), Amazon S3 (enterprises)
Input and Output Devices
- Allow users to provide data and instructions to the computer and receive results
- Part of a computer's user interface
- Selection should be based on organizational goals and specialized functions
Input Devices (Common Personal Computer)
- Keyboard and mouse
Input Devices (Motion Sensing)
- Motion-sensing input devices
Input Devices (Scanning Devices)
- Scanning devices
Input Devices (MICR)
- Magnetic Ink Character Recognition (MICR) devices

Input Devices (Other)
- Bar-code Scanners
- Radio Frequency Identification (RFID) Devices
- Pen Input Devices
- Touch Screens
- Biometric Devices (Iris Scanner, Fingerprint Scanner, Heart-Rate Monitor)
Output Devices
- 3D Printers:
- Create objects from three-dimensional models
- Key advantages: prototyping, customization
Multimedia Technologies
- Haptic Technology
- Virtual Reality
- Augmented Reality
Haptic Technology
- Simulates touch sensations for enhanced user interactions
- Replicates tactile sensations, making user interfaces more intuitive
- Applications: smartphones, VR gloves, gaming controllers (PS5 DualSense)
Virtual Server
- Virtualization: logically dividing resources of a physical server to create multiple logical servers
- Each logical server acts as an independent machine
Data Center
- Climate-and-access-controlled building(s) housing computer hardware for organization's data and information services
- Construction considerations: reduced energy use, location with milder climates and lower costs
Summary
- Careful selection of computer hardware is critical for meeting the evolving needs of organizations and their information systems
