• Personal / Microcomputers– single-user, usually single processor, compact– desktop, laptop, palmtop, PDA, specialized
• Mid-range Systems (Servers)– may have more than one microprocessor, typically
multi-user & focused on a functional area or task (marketing, plant management, web server).
– Vintage midranges (proprietary OS): IBM AS/400, DEC VAX
– Servers (UNIX/Win): Intel-based, Dell, HP, IBM, Sun
Types of Computers (cont.)
• Mainframes (IBM)– large, expensive computer, supports multiple user groups,
terminals, run several applications at once.– costly: support staff, air conditioning, software– secure: centralized programs & data are relatively easy to
backup, maintain, upgrade, and monitor
• Super Computers (NEC, IBM, Hitachi, HP, Intel, Cray)– massively parallel and/or clustered– used to solve problems requiring long, difficult calculations
