Potential uses, reasons for purchasing, and principles in selecting a personal computer for the office or home are described. The decision to purchase a personal computer involves acquiring basic knowledge, determining generic software needs, selecting appropriate hardware, designing the system on paper, determining costs, selecting a vendor, and purchasing and implementing the system. The user should start with basic equipment and add to the system as technology and his own proficiency advance. A personal computer should be designed for growth (adaptability), because equipment can quickly become obsolete. Purchasing a personal computer requires an organized approach and a substantial time commitment both for research before selecting a computer and for becoming a proficient user.
