Study Notes
Motherboards and Form Factors
- Motherboard form factors include ATX, Micro-ATX, and Mini ITX, which dictate component attachment, power supply type, and computer case shape.
- ATX supports integrated I/O ports and offers more expansion slots compared to Micro-ATX which is smaller and has fewer slots.
- Mini-ITX is designed for low power consumption and requires minimal cooling.
Motherboard Headers and Power Connectors
- Motherboard headers are the ports for USB, video, and sound connections directly linked to the board.
Adapter Cards
- Adapter cards enhance computer functionality by adding controllers or replacing faulty ports.
- Types of adapter cards include:
- TV Card Tuner: Receives TV signals.
- Wireless NIC: Connects to networks using radio frequencies.
- Network Interface Card (NIC): Connects to networks via cable.
- Video Adapter: Provides video output.
- eSATA Adapter Card: Adds eSATA ports.
- USB Controller Card: Expands USB connectivity.
- Sound Adapter: Offers audio capabilities.
Storage Devices
- Solid-State Drives (SSD): Non-moving, faster, reliable, and power-efficient by using non-volatile memory, more costly than HDDs.
- Hard Disk Drives (HDD): Non-volatile storage retaining data without power, common in laptops/desktops.
- Removable Storage Drives (RSD): Include USB flash drives and external hard drives for easy removal.
- Optical Drives (OD): Use laser technology for reading/writing data from discs like CDs, DVDs, and Blu-rays.
Redundant Array of Independent Disks (RAID)
- RAID combines multiple drives for enhanced performance, error tolerance, and storage capacity with methods like striping and mirroring.
Printer Types and Maintenance
- Laser Printers: Require HEPA vacuums for cleaning; monitor toner levels to prevent quality issues.
- Inkjet Printers: Can malfunction with incorrect ink; dust accumulation hinders printing.
- Thermal Printers: Maintenance includes cleaning the heating element and replacing paper.
- Impact Printers: Regularly check ribbon and print head for quality.
- 3D Printers: Regular cleaning and component replacement for optimal performance.
Printer Connectivity and Servers
- Printers connect via Bluetooth for mobile printing or Wi-Fi supporting 802.11 standards.
- Print servers manage printer access and job queues; can be software or hardware-based.
- Dedicated print servers are suited for larger networks, requiring robust resources.
Printer Security
- Secure printing by controlling access, disabling internet printing, updating firmware, and changing default passwords to safeguard against unauthorized access.
Scanners
- Scanners convert physical images into digital files for storage or editing.
- Types of scanners include:
- Flatbed Scanners: Original documents are placed on a glass plate.
- Sheet-fed Scanners: Documents are automatically fed through.
- Handheld Scanners: Portable and used for on-the-go scanning.
- Drum Scanners: High-resolution capture primarily for images.
Scanner Components
- Key components include the lid/cover, glass plate for originals, scanning head, and stepper motor for movement during scanning.
