There are several main types of computers: PCs which are designed for general use by individuals; desktops which are non-portable and meant to stay in one location; laptops which are portable versions of PCs with integrated keyboards and displays; netbooks which are even smaller and less powerful laptops focused on cost-effectiveness; workstations which are more powerful desktops for specialized tasks; and servers which are optimized to provide network services to other computers through powerful hardware and large storage.
