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.
