Study Notes
Printer and Scanner Differences
- Printers convert digital data to physical copies.
- Scanners convert physical data to digital data.
- Printers can be connected via USB or wirelessly.
Scanner Types
- Flatbed Scanners
- Offer good value and scan a variety of sizes
- Scan large items like books
- Often built into multifunction printers (MFPs).
- Paper Fed or Sheetfed
- Smaller than flatbed scanners
- Feed documents into the scanner
- May sacrifice resolution for size
- Drum Scanner
- Capture the highest resolution from an image
- Wrap the document around a drum
- Used for high-quality photos needing print reproduction
- Handheld Scanner
- Portable device for scanning documents
- Stores, edits, transfers, and emails scanned documents digitally
- Can scan barcodes
- Portable Scanners
- Travel-friendly and some are pocket-sized
- Lower resolution scans, not ideal for photos
- Photo Scanners
- Specialized for high-resolution scans of photos, negatives, and slides
- Include software to clean up old photos
Printer Types
- Impact Printers
- Use mechanical components to print
- Use needles against ribbon for character output
- Non-Impact Printers
- Use a mechanism to transfer ink onto paper
- More expensive than impact printers
- Can print images
- Ink Jet / Bubble Jet Printers
- Use ink for printing
- Quality determined by DPI (Dots Per Inch)
- Dot-Matrix Printers
- Use pins striking an ink ribbon to create dots
- Dots combine to form characters and images
- Laser Printers
- Use a toner and an internal laser to print
Core Aspects of Computer Technology
- Hardware - Physical components of a computer.
- Software - Set of instructions for the computer.
- Peopleware - People who maintain, operate, program, and analyze the computer system.
Software Types
- Application Software - For user benefit (ex. Word Processor).
- System Software - For the computer's benefit (ex. Operating Systems).
