Things to look for when Purchasing a PC
First and most important is what environment is the computer going to be used in there are two basic categories with everyone needing their own requirements :BusinessHome
DefinitionsHard drive – what stores from your computerRAM- Memory that help process information
and help run programsProcessor- The brain of the computer - the
device capable of performing operations on data
Gigabyte – 1,024 Megabytes Normal storage unit
DefinitionsGraphics card- Helps computer process
graphic informationUSB- universal serial bus a way to help the
computer connect more devicesOperating system - A computer program that
controls the components of a computer system and facilitates the operation of applications
CD/DVD rom- optical drives that allows the computer to read optically stored data
Business useBusiness computers serve different needs for
every business First use in the business is for the userSecond is as the server in the businessThird is for graphical design for the business
Business user computerFor a basic desktop or laptop office computer the
following specifications are a good guideline:
1 GB of ram – that will allow for speed but at a cost effective price 40 GB hard drive or more – that will allow for installation of the
operating system (files are assumed to be stored on a server) 1.6 GHz – 2.2 GHz Processor (dual core) – this will allow for a
fast computer Integrated graphic card if your business is not a graphical
design business CD/DVD ROM – For security reasons stay away from a burner 2 USB 2.0 ports – on the front of the tower for easy access to it
but 6 is recomended Operating system – Windows XP Professional( SP2), or Windows
Vista Business, make sure the computer is VISTA ready. Software – Office applications, spyware, pop up blocker, virus
software, a NetOP type program.
Business Power UserFor a Graphical oriented business
2 GB of ram – this will allow for all the speed needed to run the highly demanding software
120 GB hard drive – this will allow for the use of space needed for this environment
2.6 GHz – 3.0 GHz processor (dual core) – this will allow the computer to run all the demanding applications
CD/DVD ROM/burner – The burner might be needed so the user could save some of their projects for use at a later time
2 USB 2.0 ports – on the front of the tower for easy access to it, 6 recommended
Graphics card – 256 MB good used for the programs Operating system – Windows XP Professional( SP2), or Windows
Vista Business, make sure the computer is Vista ready. Software – Office applications, spyware, pop up blocker, virus
software, a NetOP type program, and programs like CAD, Photoshop, or video editing software
Smaller Business Server (10- 50 users)
This is for a smaller business that will not need as much as a larger one
2 GB of ram – this will allow for a fast operation and data use 500 GB+ storage in RAID array – this will allow for a lot of data
storage for smaller files 2.0-2.6 GHz processor – this will help the computer run smoothly CD/DVD ROM drive – will not be used much only for installation 2 USB – ports will be necessary figuring this computer will not be
operated on much Operating System – Windows Small Businesses Server 2003
would be the best. It is simple to use and has a lot of help that comes along with it
Large business (50+ users)For large corporations with single or multiple
locations that are not HPC corporations
4 GB+ of ram – will be needed for faster use 1 TB+ of storage in a RAID array– will be need
for users to save files 3.0+ GHz Processor (s) (dual core) – will be
needed for sufficient computing power CD/DVD ROM drive – will not be used much only
for installations Operating System – Windows Enterprise Server
2003 or Linux based software system
The second group is home users this one is a little more tricky the user should thing of a few things before purchasing the computer What will they be using the computer forHow long before they want to upgrade nextHow much do they want to spendDo they want to play graphical gamesDo they want to do any kind of editing like

computer for just basic internet (checking e-mail, browsing, and instant messages)512MB – 1GB of RAM – this depends on how much the
user wants to spend also if they want to use Windows Vista
