Computer Files

Home Directory

All student accounts have an associated home directory. This is automatically mounted when you log on to any machine in the CSIS dept either using linux or windows. Your home directory is retained on a file server seperate from individual lab machines. It is backed up regularly. In lnux each student is allocated approximately 80mb of disk space for their home directory. Under linux when you log in you will be placed in your own home directory and it will be something like

/users/ugstud1/c1234567

Under windows your home directory is mounted on the H: drive.

Students can save their work on either Floppy or Zip disks. Both floppy and zip disks are available on all PC clusters. The following sections describe the use of disks, finding files, viruses and the importance of making backup copies of all your computer files.

Floppie Disks

Floppy disks are a sensitive part of your computer system and are enclosed in a square outer casing to protect them.

It is recommended that you use labeled diskettes from any leading manufacturer. Data transfer between such diskettes can be unreliable and in the worst case their use can damage disk drives and possibly all other diskettes you try using in the drive.

Any blank diskettes you buy need to be prepared before you can use them to store any programmes or data. The storage area of a new diskette needs to be marked out in sections electronically. This process is called formatting. You have to format specially any new diskettes you want to have ready for storing the data files your programs produce.(In windows this can be done by right clicking on the A:\ drive in explorer, and then selecting foprmat from the drop down menu.)

The reading window is the gap in the casing through which the computer reads and writes data on the diskette. You must be particularly careful never to touch the diskette through this window; even the grease on your hands can spoil the data stored on the disk. If the Write Protect Notch is in place the PC will be able to read data from the diskette but it will be unable to write data to it. Such a diskette is described as write protected.

Important Points

Never take a diskette out of a drive while your PC is reading from it or writing to it.
Don't try to force open a diskette's plastic casing or poke anything into it.
Don't store diskettes anywhere they could get damp, hot or cold.
Don't store diskettes anywhere near a magnet
Treat floppy diskettes with due respect and you will get good service from them.
Always store your diskettes in a box made of hard durable material.
Buy floppies with a 'plastic gate' at the top rather than metal

Zip Disks and Drives

Zip disks are inexpensive, reliable and ready to help you get organised. Zip disks are 20 times faster, and have 70 times more capacity than a floppy. You can copy, move, delete files to and from zip disks exactly as you do with floppy disks.

Use zip disks to:

Expand the storage of your computer - quickly and easily - 100MB at a time.
Move your work easily to different locations and computers.
Backup quickly and easily.
As backup Zip disks.
Store large scanned or downloaded files from the Internet.
Take work home or on the road with you.
Archive old files and e-mail (important as students do not have backed up filestore).
