Purchasing TipsLaptop and Notebook ComputersLaptop computers provide a great deal of mobility. Due to their small size, laptops cost more than desktop computers and contain less computing power. Many built-in features of desktop computers — such as Network Interface Card (NIC), modem, CD-ROM, CD-RW, DVD, and others — do not come standard in all laptop computers. Screen size and hard disk space will be smaller as well. The portability of laptops increases the risk of damage or theft.MonitorsGenerally speaking, get the largest monitor possible. Monitors retain their value longer than other computing components and have a high impact on personal productivity. For a person who works with a computer almost constantly, a 17-inch monitor should be the minimum size to consider. A 19- to 21-inch monitor would be desirable, since it provides the best resolution and display speed possible. Flat-panel monitors take up minimum work area space, have lower power consumption and generate less heat. They are priced higher than CRT monitors, but are considered a better buy due to their lower energy consumption and heat production.MemoryWith operating systems becoming more sophisticated and applications more complex, the demand for more computer memory is constantly increasing. Currently, 512MB of random-access memory (RAM) is adequate, with expansion capability to 1GB for high-end sizing being important in optimizing the lifespan of the computer.Hard Drive/Removable MediaWhen considering the size of the hard drive (disk), consider backup capability. A single large disk without backup capability leaves the department vulnerable to significant losses in information and productivity. Removable media backup options (e.g., USB memory keys or CD-RW) or connection to a backup server should be considered a high priority.DVD/CD-RWA DVD/CD-RW combination drive allows the advantage of having a DVD-ROM, a CD-ROM, and a CD burner on a single drive. This saves bay space for future expansion. Long-lifespan configurations should include 48x for reading, 24x for rewriting and 48x speed (or faster) for writing, because software (especially operating systems) is increasingly distributed on this media. DVD drives have excellent multimedia capabilities, but run slower than CD-ROM drives.Desktop vs. Tower UnitChoose the case that best suits your work environment. Turning a computer on its side may damage components. Choose a tower case for freestanding computers and a desktop case for computers that will lie flat on a desk or table.Extended WarrantyAll machines come with a three-year, next-business-day, on-site service warranty.Windows Hardware RepairSee the TigerTech computer repair page for specific hardware support details. |
