The first computers were people! That is, electronic computers (and the earlier mechanical computers) were given this name because they performed the work that had previously been assigned to people. "Computer" was originally a job title: it was used to describe those human beings (predominantly women) whose job it was to perform the repetitive calculations required to compute such things as navigational tables, tide charts, and planetary positions for astronomical almanacs. Imagine you had a job where hour after hour, day after day, you were to do nothing but compute multiplications. Boredom would quickly set in, leading to carelessness, leading to mistakes. And even on your best days you wouldn't be producing answers very fast. Therefore, inventors have been searching for hundreds of years for a way to mechanize (that is, find a mechanism that can perform) this task.

有关专家建议，应注意做到以下几个方面：
Concerned expert advice, should pay attention to do the following aspects:

防高温家用电脑连续使用时间过长，机内温度上升，热量难以散发，会造成半导体材料老化，电路出现短路等故障。
Prevent high-temperature home computer use continuously for a long time, the temperature rise, quantity of heat inside machine difficult to send out, can cause semiconductor materials ageing, short-circuit fault. Such as circuit appear

因此，使用时间不宜超过4小时。
Therefore, use the time is unfavorable exceed 4 hours.

如果使用必须超过4小时，中间可关机休息片刻，让电脑降温。
If you use more than 4 hours, a moment of rest can be shutdown among computer, let cool.

为了避免电脑过热，不可让阳光直接照射，更不可靠近暖气、电炉、空调等热源。
In order to avoid computer overheating, let not direct sunlight, more do not close to central heating, stoves, air conditioning heat source.

一般说来，家用电脑的环境温度在16℃~26℃为宜。
Generally speaking, the home computer environment temperature in the 16th ℃ ~ 26 ℃ advisable.

防潮湿室内过分潮湿会使机器表面结露，引起机内元件焊点引线锈蚀发霉，造成断路或短路。
Preventing moisture indoor excessive moisture can make the machine surface condensation, cause inside machine compenent solder fuses corrosion caused by or short circuit breakers, moldy.

磁盘也会因湿度不宜而霉变，致使所存信息被破坏。
Disk will also because humidity is unfavorable and mildew, cause stored information was damaged.

同时，使用发霉磁盘对驱动器也会造成损坏。
Also, use moldy disk to drive also cause damage.

因此，在霉雨及阴雨天里，应经常对其通电加温，以驱除电脑内部湿气。
Therefore, in MeiYu and YinYuTian, often should of its electricity heating, remove the internal moisture.

防低温家用电脑在0℃以下往往就不能工作，也容易发生故障，如要使用，应采用热空调保温，使其能在正常温度下工作。
Prevent cryogenic home computers at 0 ℃ below often cannot work, also prone to failure, if want to use, should use hot air conditioning heat preservation, make its can in normal temperature.

防烟尘烟尘是家用电脑的大敌，它有可能渗进电脑最重要的储存设备——硬盘，对硬盘造成极大的损害。
Prevent soot dust is the enemy of home computers, which may be the most important leaking into computer storage equipment - for hard disk, caused great damage.

因此，使用电脑时，必须禁止吸烟；
Therefore, use computers, and must stop smoking,

电脑用过之后，最好让它稍凉一会儿，再盖上防尘罩；
Computer use, after had better let it slightly cool a little and then cover dust-proof covers,

当屏幕积尘太多时，最好用无水酒精棉球从屏幕中心向外擦拭；
When the screen dust too much, it is best to anhydrous alcohol sponge outward from the center of the screen wiped;

键盘、机箱也要定期除尘。
Keyboard, box, also want dedust regularly.

除尘工作应在断电下进行。
Dust removal work should be in power.

防噪声所有噪声源如马达的轰鸣、机械震动、汽笛、以及音箱的开机等都会影响电脑的运行，而且易致数据丢失和传输错误。
Prevents noise all noise sources such as motor roar, mechanical vibration, sirens and speakers boot etc will affect the computer operation and easy to cause loss of data and transmission error.

因此，电脑应放在安静的地方。
Therefore, the computer should be put in place quiet.

防震动电脑内部部件多为接插件或机械结构，在震动条件下会使其松动，以致影响整机工作。
Shockproof dynamic computer internal components for connector or mechanical structure, in vibration condition will make its loose, so that affect the whole machine working.

因此，家用电脑宜放置在专用工作台上避免受震。
Therefore, home computers appropriate places in special working platform avoid hard-hit.

防磁不可将电脑放置在彩电、组合音响、电话、电风扇等带有磁性的物品周围。
Antimagnetic not putting computer in color television, combined sound, telephone, electric fan etc contain magnetic items around.

因为它们在工作时会产生电磁场，会导致磁盘上的信息遭受损害。
Because they are generated as electromagnetic fields, can lead to disk information being damaged.

防电压波动家用电脑一般宜在220V±10％的电压条件下工作，电压过高或过低都会使电脑过载或失控。
Prevent voltage fluctuation home computer general appropriate in 220V + 10% of the voltage under the working conditions, the voltage too high or low will make the computer overload or abuse.

所以,有条件的家庭最好配备稳压电源和不间断电源UPS。
So, conditional family best equipped with manostat and uninterruptable power UPS.

电脑电源与家用电器电源应尽量分开，以减少电器起动电压、尖峰电流对电脑的波动冲击。
Computer power and household appliance power should as far as possible, in order to reduce electrical separate starting voltage, peak current for computer fluctuations impact.

防雷电电脑是最怕雷击的电子设备，因为电脑对雷电释放的静电无抗拒能力，常常由于静电的干扰使电脑元件出现不容易查找的故障。
Lightning protection electric computer is the most afraid of lightning of electronic equipment, because the computer for lightning release of electrostatic without resist ability, often because of electrostatic interference make computer components appear not easy to find fault.

所以，电脑用户不仅要有建筑物避雷装置的保护，最好还要专门为电脑配备一个可防大气感应电的消雷器，也可在电脑房间铺上防静电地毯。
So, computer users should not only have corona device protection, building the best also specifically for computer equipped with a can prevent atmospheric induction electric eliminate the trolleys, also can be in computer room on the shop antistatic carpets.

尽管如此，遇到雷电交加的恶劣天气，最好不要使用电脑，并应拔掉电脑电源的插头，以保安全。
Nonetheless, meet with thunder and lightning of weather, had better not use computer, and should unplug computer power plugs, in order to protect security.

防病毒电脑一旦感染病毒，轻则影响电脑的正常工作，重则消除磁盘数据，使整个电脑系统崩溃。
Anti-virus computer once infected, light will influence the computer work normally, heavy then eliminate disk data, make whole computer system crash.

因此，电脑一定要防病毒，其方法主要是做到专机用专盘，拒用他人软盘；
Therefore, the computer must prevent virus, its method is mainly to do with special designed with others floppy disk, refus,

对新购买的系统和软件，必须进行病毒检查；
To buying a new system and software, must undertake virus-check,

系统中重要数据要定期备份；

不让电脑执行来历不明的程序等。
