As hard drives get larger and larger, we have more to lose if something goes wrong. Archiving is usually important in any business setting or for people severely into document-management systems. Your PCs data is worth a lot more than the PC itself. Spend a bit more money to treasure the data with removable storage, a simple backup scheme, and a decent electric power protection. Together they dont cost much, and they add up to data insurance. The simplest mechanism for ensuring sustained operations is to increase the ease of reproducibility. This is the reason that backups are done.Removable StorageCapacitySuper-floppy drives use high-density magnetic media and an enhanced read/ indite head design to increase disk capacity. These drives do double duty. They read and write not only super-floppy disks, but also common 1.44MB floppy disks, examples of these are Imations 120MB SuperDisk (formerly the LS-120) or Sonys 250MBHiFD drive.If you are being selective and want to archive up to 650MB of files, CD-Recordable (CD-R) and Cd-Rewritable (CD-RW) drives are a great option. CD-Rewritable (CD-RW) is another useful mean(a) for storing up to 650MB of data. These drives allow you to overwrite data previously written to a disc, so the disks are recyclable you can use packet-writing software to drag and drop curtain files to CD-RW discs or convention premastering software to write sessions to your discs, so the medium is a fairly flexible one to use.For archiving larger files, high-cap acity cartridge drives, such as the Jaz and Jaz2, fracture 1GFB and 2GB ... ...sF.DAT DrivesG.MO DrivesH.Jaz Drives15.Matching the appropriate storage technology to an application is a balancing act between E.cost, performance, and capacityF.what you like and what you can affordG.what Packy recommends and what you wantH.What your boss tells you to buy16.To protect your documents from havoc, you simply must performE.Regular maintenance on your PCF. regularly scheduled backups,G.format your hard drive regularlyH.Spellchecker17.Most tape manufacturers recommend E.You transmutation tapes regularlyF.You do a combination of full backups and incremental backupsG.You rely on your hard driveH.You pray that nothing will happen to your work18.Incremental backups typically require ____________ capacity then full backups?E.More storageF.Less storageG.The same storageH.None of the above19.Spend a bit more money to protect the data withE.Removable storage, a simple backup scheme, and a decent electric power protection.F.A better PC and a ZIP DriveG.Calling in a good electrician H.Cat 5 wiring and a Network Technician20.Super-floppy drives useE.120MB SuperDiskF.1.44 Floppy DiskG.CD-R DisksH.Both A and B
