EVALUATION

2. POWERPOINT OUTLINE

3. HARDWARE
CONSISTS OF THE PHYSICAL
DEVICES ASSOCIATED
WITH A COMPUTER SYSTEM.

4. COMPUTER HARDWARE- REFERS TO THE
PHYSICAL PARTS OF A COMPUTER AND
RELATED DEVICES. INTERNAL HARDWARE
DEVICES INCLUDE MOTHERBOARDS, HARD
DRIVES, AND RAM. EXTERNAL HARDWARE
DEVICES INCLUDE MONITORS, KEYBOARDS,
MICE, PRINTERS, AND SCANNERS.

EVALUATION FACTORS

12. HARDWARE
DECISION
Modularity/
expandabity
Ergonomics
Software
availability
Vendor
Cost
Performance
Compatibility

13. EVALUATING HARDWARE CAN BE A
COMPLICATED PROCESS. FOR SCHOOL
DISTRICTS WITH LARGE MAINFRAME
COMPUTER SYSTEMS, ACQUIRING
HARDWARE MEANS INVESTMENT OF
MILLIONS OF DOLLAR FOR MANY YEARS IN
A PARTICULAR VENDOR. IN THE PUBLIC
SECTOR, ADMINISTRATORS WILL LIKELY
USE COMPETITIVE BIDING PROCEDURES
THAT MAY REQUIRE IDENTIFYING A
FORMALIZED EVALUATION PROCEDURE TO
PROSPECTIVE BIDDING. BACK

14. ARE VERY IMPORTANT FACTORS FOR LONG-
RANGE PLANNING. MODULARITY, REFERS TO
THE INTERCHANGEABILITY OF COMPONENTS
OR PARTS OF A HARDWARE SYSTEM.
EXPANDABILITY, IS THE ABILITY OF COMPUTER
HARDWARE TO GROW OR EXPAND AS A NEW
APPLICATIONS ARE DEVELOPED OR AS OLD
APPLICATIONS BECOME LARGER. TECHNOLOGY
IS CONSTANTLY EVOLVING. TO EXPAND NEWLY
PURCHASED EQUIPMENT SHOULD NOT
REFLECT OLD TECHNOLOGY BEING PHASED
OUT. Back
