What is computer equipment? The display belongs to the output device of the computer.
The external equipment of computer system includes keyboard, mouse, scanner, digital camera, voice input system, handwriting input system and IC card input system.
What is ZAN computer equipment ZAN = = & gtZoor Aess Neork is a multi-layer Ethernet switch.
There are many technologies to realize broadband access, among which FTTx+LAN is one of the most popular technologies. The so-called FTTx+LAN technology is based on optical fiber to the community, using computer local area network to access end users, using optical fiber plus five types of lines, and Ethernet switching technology to achieve "Gigabit to the community, 100 megabytes to the building, 100 megabytes to the home." This broadband construction scheme can provide a variety of broadband services based on IP technology.
The basic architecture of FTTx+LAN scheme is as follows: a Gigabit Ethernet switch (ZAN equipment) is set in the community, and a Layer 2 Ethernet switch is set in the building, which is connected with ZAN equipment through 100 Mbit/s optical port. In order to ensure the information security of users, the telecommunications department requires information isolation between the ports of broadband access equipment, that is, any information exchange between the two ports must be completed through ZAN equipment.
What are the computer equipment? Keyboard, mouse, scanner, intelligent voice input system, intelligent manual tablet and so on are all input devices.
Monitors and printers are both output devices.
Network cards, hubs and routers are all network devices.
Electronic circuits and physical devices used in computer systems are tangible entities, such as central processing unit (CPU), memory, external devices (input and output devices, I/O devices) and buses.
1 memory. The main function is to store programs and data. Program is the basis of computer operation, and data is the object of computer operation. The memory consists of memory bank, address decoder, read-write control circuit, address bus and data bus. The memory that can directly and randomly access instructions and data by the central processing unit is called the main memory, and the large-capacity memory such as magnetic disk, magnetic tape and optical disk is called the external memory (or auxiliary memory). The storage system of a computer consists of main memory, external memory and corresponding software.
② The main function of the central processing unit is to execute the operations specified by the program one by one according to the programs in the memory. The main components of the central processing unit are: data register, instruction register, instruction decoder, arithmetic logic unit, operation controller, program counter (instruction address counter), address register, etc.
③ External equipment is the bridge between users and machines. The task of the input device is to convert various forms of information that users require the computer to process, such as data, characters, characters, graphics and programs, into a code form acceptable to the computer and store it in the computer. The task of the output device is to output the processing results of the computer in the form required by users (such as screen display, text printing, graphics and charts, language sounds, etc.). ). I/O interface is a buffer device between external devices and CPU, which is responsible for electrical performance matching and information format conversion.
What are the responsibilities of computer equipment users? First, the computer room administrator must have high ideological awareness and be conscientious and responsible in his work.
Second, often educate students not to talk loudly when entering the computer room, and enter each post in an orderly manner to prevent equipment damage.
Third, the computer room must be kept clean and tidy, and the equipment should be placed in an orderly manner.
Four, enter the computer room personnel must be clean and tidy, and put on slippers to enter.
Managers must know the relevant computer knowledge and be able to repair minor faults.
Six, to ensure the normal operation of each machine, to ensure the normal teaching order.
Seven, education users should take good care of public property, if there is any intentional damage should be compensated.
Eight, the use must be recorded, the maintenance must also be registered, and the account information must be carefully prepared.
Nine, every computer should be registered by number.
Ten, the person in charge must also do a good job in computer training for relevant personnel and teach them how to use it. Be kind to people.
Eleven, every day after use (especially before going to school) should be timely check whether all machines have been shut down, whether the regulated power supply is closed, whether the doors and windows are locked. Do a good job in network security management every day.
Twelve, such as school economic losses caused by dereliction of duty, the staff should bear the corresponding responsibility.
How to identify the computer equipment with comments? Generally, a better note is marked by laser, and the text color and image on the note are very similar, but there will be subtle differences in small parts. On the other hand, remark needs to remove the previous text, generally polishing off a very shallow layer, which will leave a rough part on the surface. So observing whether the surface is smooth, just like in other places, can roughly judge whether it is a remark.
How to prolong the service life of computer equipment From the perspective of system maintenance, this paper expounds the necessity of maintaining computers and computer equipment. Extend the service life of the computer and improve the utilization rate of the computer. As long as the voltage is stable, there is no problem. The speed of upgrading computers in Internet cafes is far greater than the service life of computer equipment. Other large-scale equipment (air conditioners) that use electricity should not use the same cable as the computer.
