Seek the hardware connection equipment, network card and communication cable in the computer network. Urgent!
The personal computer is a small network, a variety of input devices (keyboard, mouse, handwriting, Mike, scanner, camera, digital camera, etc.) the output device (monitor, printer, projector, audio, etc.), data calculation unit (CPU CPU), storage (memory, hard disk, U disk, CD-ROM the memory card, etc.) through the computer motherboard and the adapter (video card, sound card, including a card, and some have been integrated on the motherboard) connected together. The network can be viewed as separating and amplifying the functional components of a computer. With the development of computer technology, the network is developing constantly. Because of the development of network, the human being's production and life are being influenced more and more deeply. Intelligent mobile phone (handheld computer), intelligent home appliances, home appliances and other cloud is the personal computer (PC) to extend the application, network computing, network storage, network printing (SkyDrive) and a new generation of faster communication transmission technology, so people gradually out of the shackles of the desktop. The Internet is everywhere, and the Internet is the computer.
Network terminal to complete a variety of practical applications; photoelectric signal transmission lines of communication, connecting the terminal; because of the modern digital computer processing of digital signal, digital signal and direct transmission attenuation, interference, distance limitations, so the network connection requires a modem (CAT) bidirectional conversion between the analog digital signal transmission computer processing and communication lines in the network adapter; (NIC) responsible for the network to send / receive data transmission control, data buffer and signal matching.
The computer network includes network terminal (PC, workstation, computer center, print / file server, data storage server), network adapter (NIC) and the modem (CAT), communication lines (cable, cable, wireless transmitting / receiving equipment, etc.).
