Chap 5: Hard Drives

Chap 5: Magnetic HD

Chap 5: Hard Drive structure

Chap 5: Solid State Drives

Chap 5: SSD

Chap 5: Hard Drive Interfaces 2.5'' (for laptops usually) 3.5'' PATA (older) 3.5'' SATA(newer)

Chap 5: PATA

Chap 5: PATA Jumpers

Chap 5: Slow PATA

Chap 5: SATA

Chap 5: Fast SATA

Chap 5: SCSI ID# 7

Chap 5: Hard Drive Considerations Capacity: How many GB/TB? Spindle speed: 7200RPM? 10000RPM? Cache/Buffer: How many Mbs? Interface standard: PATA? SATA? SCSI? USB?

Chap 5: RAID Not RAID - Spanning or JBOD RAID 0 – Striping RAID 1 – Mirroring RAID 5 – Striping with parity (3 Disks minimum) RAID 10 (1+0) – Striping and Mirroring (4 Disk minimum) RAID takes special hardware or software. Windows has RAID support in software, but it would be better to use RAID hardware.

Chap 5: Tape Backups Can hold tons of data and are very inexpensive! Can be very slow 6 TB for $30

End of Chap 5! We made it!

Chap 6: Supporting Input/Output BASIC PRINCIPLES: Devices are controlled by software Some devices need special applications A device cannot be fast that the port it is in Problems can be solved by updating driver Sometimes Install only one device at a time

Chap 6: Device Manager

Chap 6: Device/Task Manager To access Task Manager: Press Ctrl+Shift+Esc Or Press Ctrl+Alt+Del and select Open Task Manager

Device/Task Manager Group Project Groups of up to 5 ANSWER AND TO 1. What is the name of your computer? 2. Who manufactured your hard disk drive? 3. Who manufactured your CD/DVD drive? 4. What type of keyboard is installed? 5. Which network adapters are installed? 6. What processor is installed? How many cores does it appear to have? 7. About how much RAM is in use on your computer? 8. Which process is using the most memory?

Chap 6: Connections and speeds

Chap 6: USB connections There's a lot of em. There will be a really cool picture here when this slide is ready. The picture will show all the different USB connectors. It's so cool. But this slide isn't ready yet. Instead, here's link to me playing the saxophone: Y
