Some basic terms

NAT translates a public IP address into a private IP address, also known as port ing or port forwarding. using a route means that ADSL has a dynamic or fixed public IP address. ADSL is directly connected to the HUB or vswitch, and all computers share the internet. At this time, there is only one external address for ADSL, such as 61. 177 .*.*. The internal IP address is set manually. For example, if ADSL is set to 192.168.0.1, the following computers are set to 192.168.0. * (* Indicates 1, 2, 3 ,...).

Voip (voice over internet protocol) is a grouping and digital transmission technology based on ip technology. Its basic principle is to compress and encode the voice through the speech compression algorithm, then, package the voice data by ip address and other related protocols, transmit the data packets to the destination through the ip network, and then concatenate the voice data packets. After decoding and decompression, the original voice signal is restored to achieve the purpose of transmitting voice over an IP network. The biggest advantage of voip is that it can widely use internet and Global ip interconnection environments to provide more and better services than traditional services. Voip can deliver voice, fax, video, and data services cheaply over an IP network, such as unified messaging, virtual phone, virtual voice/fax mailbox, account checking service, internet call center, internet call management, video conferencing, e-commerce, fax storage and forwarding, and storage and forwarding of various information..

3G: 3G stands for 3rdGeneration, which is the third generation mobile communication technology. Compared with the first generation of analog mobile phones (1G) and the second generation of GSM, TDMA and other digital mobile phones (2G, it is a new generation mobile communication system that combines wireless communication with multimedia communication such as the Internet. It can process images, music, video streams, and other media forms. It provides various information services, including web browsing, teleconference, and e-commerce. To provide this service, wireless networks must support different data transmission speeds, that is, they can support at least 2 Mbps (MB/second) in indoor, outdoor, and driving environments) the transmission speed of 384 kbps (kilobytes/second) and kbps.

NGN: Next Generation Network)

VLAN (Virtual Local Area Network) is also called Virtual LAN

Session Initiation Protocol is an IP-based application-layer control Protocol defined by IETF. Because SIP is a plain text-based signaling protocol, it can manage meetings on different access networks.

SNMP is the abbreviation of "Simple Network Management Protocol", which means "Simple Network Management Protocol" in Chinese ". SNMP was first proposed by an Internet Engineering Task Force (IETF) research team to solve router management problems on the Internet.
SNMP is currently the most common environment management protocol. SNMP is designed to be Protocol Independent, so it can be used on IP, IPX, AppleTalk, OSI, and other transport protocols used.

The Common Object Request Broker Architecture refers to the Common Request proxy system. The objects on one computer can call the Object methods on another computer. Using the Object Request proxy (ORB), CORBA uses accessible objects. ORB connects two objects through the network. Objects on one computer (client object) Use ORB to call object methods on another computer (Server Object. Corba orb is a middleware. The Remote Procedure Call (RPC) in the broad sense ).

FUPRID factor: You can classify user interface problems by FUPRID.
F = Feature features
U = User interface
P = Performance
R = Reliability
I = Installability
D = Documentation docalization
The following is not a strict definition, but a description that can be further understood.
Features refer to the fields and user interface functions that meet the task requirements.
User Interface refers to the full image (appearance), behavior and user interaction (feeling) to complete user tasks ).
Performance includes the evaluation of batch processing or the entire background task.
Reliability is interpreted as the basic quality of a product. It is referred to as zero defect behavior.
Installability refers to the setup and installation of easy programs, which is related to the first use of the software.
Documentation includes all forms of user assistance and performance support documentation. Whether it is in the form of hard copy or online help, documents are required to provide support information for product use.
