Study Notes
Hardware Components
- The power supply component of a computer might need its switch changed when moving from one country to another.
- Optical discs with a "DL" (Double Layer) suffix have a capacity roughly twice that of their standard counterpart.
Flash Storage
- The smallest flash cards possible are MicroSD cards.
- USB Type-C is a reversible type of USB.
Motherboard and Power Supply
- The primary power supply connectors connected to ATX and then to the motherboards have 24-pin counts.
- SATA connections provide the fastest data transfer speeds for hard drives.
Networking and Internet
- For a user to remain connected to the Internet while using a laptop outside the house, cellular networks or mobile hotspots are the best choice.
- HDMI connections use a single connector to deliver both video and audio without using any conversion adapter.
RAID and Storage
- To configure two drives for maximum performance, RAID 0 should be used.
- eSATA cables are most likely to be used to connect to an external hard drive.
- Capture cards are used to save a video stream to the computer for later manipulation or sharing.
Expansion Cards and Bridging
- When installing multiple add-on cards of the same type, bridging might be needed to function as a single unit.
- The maximum speed difference between USB 2.0 and USB 3.0 cables is 400 MB/s.
RAID 5
- RAID 5 is a disk striping with parity, which provides both data striping and error correction.
Hot-Swappable Devices
- Hot-swappable devices are those that can be connected or disconnected without shutting down the system.
Hard Drive Technologies
