Hardware maintenance
The maintenance of computer hardware mainly includes the following points:
(1) At any time, the connection between the power cord and the signal line should be ensured to be solid and reliable;
(2) Regularly clean the head of a floppy disk drive (for example, three months or six months );
(3) computers should always be in motion to avoid long-term idle use;
(4) The external device should be powered on first, and then the host should be powered on; the host should be shut down first, and then all external devices should be turned off. After the host is turned off, it cannot be shut down immediately, nor can it be started immediately after the shutdown, the interval should be more than 10 seconds;
(5) When the floppy disk drive is being read/written, do not forcibly remove the floppy disk. Do not touch the exposed disk surface;
(6) during keyboard operations, do not press the key too heavily; otherwise, the keyboard's life will be affected;
(7) The printer's ribbon should be changed in time. When the color of the ribbon is already very light, especially when it is found that the ribbon is damaged, it should be replaced immediately to avoid contamination of the printer's needle with impurities, it affects the flexibility of the print needle action;
(8) often pay attention to cleaning the dust in the machine and wiping the keyboard and chassis surface. When the computer is not in use, it should be covered with dust-proof covers;
(9) do not move hosts and other external devices at will when powered on.
Software maintenance
The maintenance of computer software mainly includes the following points:
(1) Back Up All system software. In case of exceptions or some accidental cause, the system software may be damaged. In this case, the software system needs to be re-installed. If the system software is not backed up, it will make the computer hard to recover.
(2) important applications and data should also be backed up.
(3) Pay attention to clearing useless files on the disk to effectively use the disk space.
(4) avoid illegal software replication.
(5) Frequent detection to prevent computer viruses.
(6) to ensure the normal operation of the computer, use software tools to protect the system zone as necessary.
In short, the use of computers is inseparable from maintenance. You must pay attention to both hardware maintenance and software maintenance.
