Focus on the particulars

To make the best choice, it is important to take the following items into account:

System unit components - The system unit houses the following components:

Processor - The processor is the heart of the system and affects how fast the computer will run, as well as what software it can run. Intel processors include the Core Duo and the lower-end Pentium and Celeron. AMD processors include the Athlon and the lower end Sempron. Processor speed is measured in gigahertz (GHz; billion cycles per second).

Memory - RAM (Random Access Memory) chips provide a temporary storage area where the computer loads and retrieves the instructions it needs to run a program as well as the data on which the program will work. The larger this storage space, the faster and better your computer will perform. The amount of RAM also affects how large a program you can run and how many programs you can run simultaneously. For a minimum, don't go below 1 gigbyte (GB).

Types of RAM include DDR-SDRAM (Double Data Rate-SDRAM) and RDRAM (Rambus Dynamic RAM).

Hard drive - The amount of hard disk space determines how much room you have to store your files and programs. At a minimum, it is best to get at least 80 GB (gigabytes) for a desktop model and 40GB for a laptop. Hard drive space is relatively inexpensive and it is better initially to buy more than you think you might need. Upgrading a hard drive is a relatively big job, so it is better to avoid this, if possible. 

DVD/CD-RW drive - A DVD-ROM/CD-RW or DVD-RW/CD-RW drive is essential for installing software and backing up your files. CD-RW drives enable you to both play and record CDs. DVD-ROM drives enable you to play DVDs but not record them, while DVD-RW drives enable to both play and record DVDs.

CD-RW and DVD-RW drives are usually listed as having three speeds, such as 16X/10X/40X. The first number indicates how fast the drive writes data when creating a CD-R or DVD-R disk. A CD-R or DVD-R disc can be written to only once. The second number indicates how fast it writes data using a CD-RW or DVD-RW disk. A CD-RW disc can be written to and erased multiple times. The last number indicates how fast the drive reads a CD or DVD.

Video card - The video card provides the interface between the computer and the monitor. In order to make the most of Micorsoft Vista, the video card should have at least 128MB of memory.

Modem - A modem enables you to access the Internet over a phone line and is included with most new computer systems. The fastest modem you can buy transfers data at a rate of up to 56K (Kilobits per second). To access the Internet, you will also need an account with an Internet Service Provider.

Note: Temple recommends using a high-speed DSL or cable modem connection. This requires a network card or cable modem, instead of a standard modem, as described below.

Network card - If you live in a Temple residence hall, you can access the Internet through a high-speed Ethernet connection. To use the connection, you will need a 10/100 Base-T Ethernet card, which is usually built-in the computer.  Recommended brands include 3Com, SMC, Realtek, or D-link. You would also need an Ethernet card if you plan to use a high-speed DSL (Digital Subscriber Line) connection from your home. Note that DSL also requires a specialized DSL modem, which you can usually obtain through your DSL provider.

Also check if your Ethernet card or adaptor comes with a 10/100 Base-T Category 5 (RJ45) cable.  If not, you will need to purchase one separately. Make sure to bring this cable to school with you if you plan to use the high-speed network connection available in Temple's residence halls.

Cable Modem - You can also obtain a high-speed Internet connection through your local cable company. This requires a specialized cable modem, which you can usually purchase or rent through your cable company. 

Sound card - A sound card and speakers enable you to listen to music and other audio files. Most computers come equipped with a standard "SoundBlaster compatible" sound card that should be adequate. SoundBlaster is an industry standard developed by Creative Labs. Speakers are also often included with a new computer system. If not, you can purchase an inexpensive pair, or alternatively, a set of headphones.

Monitor - A 17" LCD monitor provides a good compromise between size and cost. The monitor should have a dot pitch of .28mm or lower (the lower the better). Make sure to try the LCD monitor before buying it, as some people find certain models difficult to view.

Software - Most computers come preloaded with the operating system (such as Windows XP Professional/Home Edition or Mac OS X) and a web browser (such as Internet Explorer). Starting January 30, 2007, new computers will come preinstalled with Microsoft Vista.

Additional software is often bundled in as well, such as a basic office program and a virus protection program. Check that the original software CDs are included, as you may need them to reinstall a program at some point.

Also, some manufacturers enable you to select optional software to be preinstalled with the computer. Before selecting optional software, however, compare the price with that offered by CampusEstore.com. Through CampusEstore.com, Temple students can purchase a variety of Microsoft and Adobe products online at up to 60% off regular prices from Journey Educational Marketing.

Printer - An ink-jet printer is a good choice because of low-cost and versatility (black & white as well as color printing) and is often included with a new computer system. Printer manufacturers include Dell, Epson, HP, and Lexmark. Temple does not endorse a particular printer brand.

Other considerations - You might also want to purchase a surge protector to protect the computer's circuitry in the event of an electrical spike. In addition, you may want to purchase CD-Rs or CD-RWs to back up your files.
