Environmental Factors Affecting Computers |
Posted: January 18, 2023 |
1. The impact of temperature on the computer The temperature of the computer working environment can not be too high or too low, the more appropriate temperature of 10- 300C temperature is too high, will make the circuit devices poor heat dissipation or even burned. Temperature is too low, will also cause device failure and mechanical part of the operation is not normal. 2. The impact of humidity on the computer The humidity of the computer working environment must also be controlled in a certain range, usually at 40%-70% more appropriate. Humidity is too high, easy to cause leakage; humidity is too low, and will cause the collection of electrostatic charge, electrostatic discharge can easily lead to the erasure of data in the memory or circuit chip is burned. When the relative humidity is below 30%, the failure rate of the computer will increase sharply to 10-30 times the normal situation. 3. Vibration on the computer impact Computer can not work in an environment of frequent vibration, computer disk drives in the contact between the head and disk in the work is very precise, a slight strong vibration that will damage the head and disk. 4. Dust on the computer impact Dust on the computer is also a very big impact, the accumulation of dust can also cause leakage, electrostatic induction, head disk wear and other failures to the computer. 5. Security of computer information system With the deepening of computer information system application, computer information system gradually develops from stand-alone to LAN and WAN, especially the rapid development of Internet, computer information system security faces new and more serious challenges. The diversity of computer operating systems and networks that form the basis of computer information systems, the mixture of various network topologies to achieve computer connectivity, the diversity of media used, and the centralized or distributed processing of information, all of these have greatly increased the difficulty of solving the security problems of computer information systems. Therefore, computer information system security is no longer the security of a certain element or elements of the system, but the security of the system as a whole, is no longer a pure and simple problem, but a system engineering. From the technical point of view, computer system security includes computer security, network security and information security.
