What features should my PC have?
This an extremely difficult question to address as with each and every individual
and each and every vendor there are many variables. However, I have found that
several items should be considered. These are ever changing targets so please consider
them in that light.

- Speed - Generally the faster (in Giga-Hertz) the computer the better,
however, speed of the computer is a total combination of all components not just the
processor. Price/performance recommendation is 2.8 GHz or higher for a desktop unit
(1.4 GHz or higher for laptops). Multiple Core processors can also improve
performance.
- Memory - Sufficient RAM (Random Access Memory) is a big factor as even
adding memory to an older system can often improve performance and extend the life
of the system. Recommendation minimum 1024 MB with 2048MB (better for Windows Vista)
or more preferred.
- Hard Disk - You'll need enough storage space for the operating system,
application software, and document storage. Minimum here 40 GB (Giga-Bytes), however,
60-120 GB may be very cost effective so check pricing. If you will plan to store lots
of audio, pictures or movies etc. then 160-250 GB or more is a good plan.
- Display - The color display should have the ability to display 1024 x 768
pixels (or better) with a refresh rate of 60 Hertz (or faster). "Viewable" screen
sizes of 14-19 inches (measured diagonally) or larger are common. Consideration of
a flat panel monitor (not CRT) since desk space will likely be an issue such as
in residense hall rooms.
- Video Card - Video cards commonly have at least 32 MB of VRAM. If
"competitive gaming" is the desire, increase this to 64 MB or higher. Digital
Video Cards should also be considered.
- CDROM/CDRW/DVD/DVDRW Drive - With the large size of system and application
files today, most software is now distributed on CDROMs. Therefore, a CDROM is
a necessity these days even on laptop computers. Speed in general is not a big factor
for loading software unless you are using the CD continuously (i.e. playing games,
video or audio). Some find they want to have a combination CDROM/DVD Burner (CDRW/DVD)
to make their own CDROMs and read/play DVD movies. This can provide a good file
backup method (also see Memory Stick, and Zip, Jaz, or Tape Drive below). The question
of should you purchase DVDRW capability to burn DVDs is left to the needs of the
purchaser, if you are planning on making DVD movies then, yes.
- Network Cards - are recommended as all residence hall rooms on the UNI
campus come with a standard Ethernet connection (for wired access) and there are
some Ethernet connections available in the library. Most system come with this
standard.
- Wireless Cards - are recommended for laptops as wireless network is
available across much of campus (but not in the residence hall rooms themselves
due to environmental challenges). Almost all laptops are now coming with both
wired and wireless network included but check to be sure. For more information on
wireless, see
http://www.uni.edu/its/us/faqs/wireless
- Floppy Drive - The floppy drive is barely used in our environment as memory
sticks are the preferred method to transport a document from
machine to machine. Students commonly use these in our computer labs. Remember,
make two copies for backup purposes! Regardless, we recommend using the newer technology
Memory Sticks which are more reliable and hold more information.
- USB Memory Sticks / Jump Drives/ Flash - These devices are the preferred
alternative to the floppy disk in our environment as it also provides inexpensive
and very flexible capability to transport a document from machine to machine.
Students commonly use these in our computer labs. A single memory stick can
hold significantly more documents than a floppy disk. The biggest problem is users
must learn to eject them correctly with the software before physically pulling them
out of the computer, we have an icon on the lab machines to simplify this operation.
Making backup copies of files from your computer's hard drive
to a memory stick is an excellent practice. These devices are also called USB Flash
Disk, Thumb Drive, Pen Drive, M emory Key, Micro Vault, Pocket Drive, KeyChain,
Pico Drive, etc. Remember, make two copies for backup purposes! SyncToy is a free
utility that provides this capability nicely.
- Speakers and Sound Card - With more information being provided with
audio and video capability plus the ability to play music CDs or video DVDs, sound
cards and speakers are rapidly becoming standard features. Speakers can range from
inexpensive (usually very adequate) to expensive depending strictly upon quality
desired. If you plan to view DVD movies from a laptop computer you may want
a set of external speakers.
- Locks - security of the computer is critical, particularly for laptop
computers on college campuses. College campuses have become attractive targets for
professional electronics thieves. Kensington&trade and other locks (very similar to
bicycle locks) are recommended for laptop computers. Consider whether a combination
or key based lock is best for your use. For convenience we sell these in the Computer
Consulting Center.
- External Portable Disk Drives - USB connected portable drives are very popular
for backing up and transporting large volumes of information. These drive are very
good for large storage situations such as movies and photographs.
- Tape, Jaz or Zip Drive - not generally recommend as these technologies
are dwindling... we
emphasize that backups (redundant copies of files) are EXTREMELY important to have
(REMEMBER, YOU have to make them!) and most are copying files to Memory Sticks or
burning CDs for this purpose. It is also an excellent idea to have the ability to
transfer your documents to an external storage device for backup purposes in case
your hard disk fails or you want to move files to another location for use or safe
keeping.
Tape Drives can offload a lot of information quickly but you often have to have the
same type of drive on your secondary computer(s) unless you have a portable unit.
Jaz and Zip drives provide high storage capacity removeable ramdon access diskette
storage. Zip drives are somewhat more common and compatible but don't hold as much
information on a single disk. With both Jaz and Zip data access is
random whereas tape access is sequential. Getting to a file at the end of a tape can
take significantly longer to access than on a Zip or Jaz disk which can be used like
a large diskette.
