1 Test Out Online Lesson 5 Schedule Section 5 MUST BE COMPLETED BY: 12/5 Section 5.1: Storage Devices This section provides an overview of storage devices. Concepts covered include: Common storage devices: o Floppy disk o Hard disk o Optical discs o Flash devices o Solid state drives o Tape drives Common storage device interfaces: o Parallel ATA (PATA) o Serial ATA (SATA) o Small Computer System Interface (SCSI) o USB/Firewire o Ethernet What are the advantages of hard disks over all other forms of storage media? How do optical drives store and read data from a disc? How does a flash device differ from a floppy disk or a hard disk? How does SATA improve upon the limitations of PATA? What is a typical application for SCSI devices? Which storage device types are magnetic media? Which are optical? Solid state? Which type of interface would you commonly use to attach a flash card reader to the computer? Storage Devices 23: Storage Device Interfaces 7:31 Total 31:18 12 questions About 55 minutes

2 Section 5.2: Floppy Drives This section discusses installing and troubleshooting floppy drives. Concepts covered include: Install a floppy drive, connecting the necessary data and power cables. How do you change the drive letter for a floppy drive? How do you identify pin 1 on a floppy drive cable? What precautions should you take with floppy disks? Installing a Floppy Drive 10:52 Install a Floppy Drive 4 questions About 25 minutes

3 Section 5.3: Parallel ATA (IDE) This section discusses installing PATA devices. Install PATA devices by setting jumpers and connecting data and power cables. With multiple devices on a single data cable, how do you identify which drive is the master and which is the slave? How should you configure a single device on one channel? What is cable select and how does it work? You have an optical drive and a hard disk in a system with two PATA channels. How should you install the devices for best performance? ATA/IDE Devices 13: Installing an ATA Device 10:05 Total 24:00 Install PATA Devices 8 questions About 40 minutes

4 Section 5.4: Serial ATA This section discusses installing a Serial ATA device. SATA standards: o SATA 1.5 Gbps (SATA 1) o SATA 3 Gbps (SATA II or SATA- IO) o SATA 6 Gbps o esata Options to configure the SATA mode in the BIOS: o IDE o AHCI o RAID Install SATA devices. Add esata ports and connect esata devices. What are the main differences between PATA and SATA? What is esata and when would you use it? Serial ATA 9: Installing a Serial ATA Device 5:33 Total 15:04 Install SATA Devices 4 questions About 30 minutes

5 Section 5.5: SCSI This section discusses configuring SCSI devices. Install a SCSI adapter in a PC system. Connect SCSI devices to a SCSI adapter. Set the ID of a SCSI device. Terminate the SCSI bus. What types of systems typically employ SCSI storage devices? How are SCSI devices connected to a PC system? What do SCSI connectors look like? What is the function of the SCSI ID number? SCSI 17: SCSI Standards 13: Installing a SCSI Adapter and Device 9:15 Total 40:17 5 questions About 50 minutes

6 Section 5.6: Optical Media This section provides an overview of selecting and using optical media. Concepts covered include: Types of Compact disc (CD) formats Digital Video Disc (DVD) basics Blu-ray Disc (BD) basics Factors to consider when selecting an optical drive: o Interface o Drive function o Speed o Format o Loading type o Cache o Additional Features Fundamentals when working with optical drives. Precautions to protect discs. How much data does a CD typically hold? DVD? Blu-ray disc? An optical drive speed is identified as 24x10x70. What does each of the numbers indicate? What is the difference between dual layer and dual sided discs? What is the difference between BD-R and BD-RE discs? CD Drives 11: DVD Drives 14: Blu-ray 6: Choosing an Optical Drive 4:03 Total 36:51 10 questions About 55 minutes

7 Section 5.7: File System This section provides the basic information about using a file system to organize and store data. Format drives. Use the Convert utility to convert a drive to NTFS. What is the difference between a partition and a volume? What advantages does NTFS provide over FAT32? Why should you back up all data before formatting a drive? How can you reformat a drive from FAT to NTFS without losing all of the data? How would you convert a drive from NTFS to FAT32? Which operating systems can use NTFS? File System 5: Viewing File System Components 12: Partitions and Disks 22: Creating Volumes 16: Formatting and Converting 17: Disk Status 3:01 Total 77:21 Create Volumes Format Drives 21 questions About 115 minutes

8 Section 5.8: RAID In this section students will learn about using a RAID array to improve performance and/or provide fault tolerance. Concepts covered include: Common RAID levels: o RAID 0 (striping) o RAID 1 (mirroring) o RAID 5 (striping with distributed parity) Methods of implementing RAID: o Hardware o Software o Operating system A typical method for configuring software RAID The steps to install the operating system on a RAID array With a RAID 0 configuration, what happens to your data if a drive in the set fails? What is the minimum number of disks required for a RAID 5 configuration? What advantages does RAID 5 have over RAID 1? RAID 13: Configuring RAID Arrays 16:41 Total 29:43 Create RAID Arrays Implement a RAID Solution 8 questions About 55 minutes
