QUESTION1 Power Problems Alternating current (AC)‚ which is “food” to PCs and other network devices‚ is normally 110 volts and changes polarity 60 times a second (or 60 Hertz). These values are referred to as line voltage. Any deviation from these values can create problems for a PC or other network device. Power problems fall into three categories: * Overage * Underage * Quality Power Overage Problems During a power overage‚ too much power is coming into the computer. Power overage

The Entity Relationship Diagram (ERD) depicts a conceptual data model that incorporates some of the important scientific information about the real world. It adopts a natural view that the real world consists of entities and relations (Chen‚ 1976). One objective of the ERD is to create a simple‚ easy to understand and conveniently presented data model consisting of entities‚ attributes‚ relationships and cardinalities. The model serves as tool for database design‚ where the model can facilitate communication

DFD Yourdon Recently reviewed In the late 1970s data-flow diagrams (DFDs) were introduced and popularized for structured analysis and design (Gane and Sarson 1979). DFDs show the flow of data from external entities into the system‚ showed how the data moved from one process to another‚ as well as its logical storage. Figure 1 presents an example of a DFD using the Gane and Sarson notation. There are only four symbols: Squares representing external entities‚ which are sources or destinations
