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

Network security Security has moved to the forefront of network management and implementation. The overall security challenge is to find a balance between two important requirements: the need to open networks to support evolving business opportunities‚ and the need to protect private‚ personal‚ and strategic business information. The application of an effective security policy is the most important step that an organization can take to protect its network. It provides guidelines about the activities
