Website UV, with IP, PV

What is the Web site UV, with the IP, PV in the conceptual difference?

UV (Independent visitor): a unique Visitor that accesses a computer client of your website as a visitor. The same client in 00:00-24:00 is counted only once.

PV (traffic): That is, Page view, that is, the amount of pageviews or clicks, the user each refresh is calculated once.

IP (standalone IP): refers to the number of independent IPs. The same IP address within the 00:00-24:00 is computed only once.

Independent IP indicates the number of times a computer with a particular unique IP address has access to your website, because this statistical method is easier to implement and has a high degree of authenticity, so it becomes an important indicator for most organizations to measure website traffic. For example, you are ADSL dial-up Internet, you dial a number are automatically assigned an IP, so you enter the site, that even if an IP, when you disconnected and did not clean the cookies, and then dial a number, and automatically assigned to an IP, you come in the site, then count to an IP, But the UV (independent visitor) has not changed, because 2 times you have entered the site.
To illustrate that PV high does not necessarily represent more visitors, PV is proportional to the number of visitors, but PV does not directly determine the number of real visitors to the page. For example, a website you come in alone, through the constant refresh of the page, you can also create a very high PV.

Ip here refers to the public Wan Transport Protocol family (TCP/IP) for each computer located on the Internet (can be PC, server and other compatible WAN transport protocol family provisions Access devices) are defined four paragraphs (for example: 192.168.0.255 form, sometimes added to the port number of the five paragraphs as descriptive information, the port number is between 1-65535 digits) a total of 32-bit length binary code identification, called IP protocol address, referred to as IP address, commonly known as IP, It is a computer that is connected to a wide area network to distinguish it from other machines, and in general it is unique within the same level of networks (for example, a LAN, a community network, a teaching building network, or the Internet).
A separate visitor is a natural person who accesses and browses a webpage through the Internet.
For example, on a computer, the elder brother opened the official homepage of Microsoft, registered a member. Brother looked at it for a while and registered another member. Since the two brothers are using the same computer, then their IP is the same, Microsoft's official counter is logged to an IP login information. However, statistical systems with statistical functions can determine the number of users actually used according to other conditions, and return the information to the website building's real, credible and accurate. For example, through the registration of users, can even distinguish between Internet cafes, computer rooms and other shared an IP address of different computers. The above example shows that although it is the same IP, there are 2 independent visitors. Another example, such as an internet café, there are 100 people have entered my site, but an internet café is an IP, so the statistical system only counted to an IP; but because there are 100 people in the Internet cafes visiting my station, although they are only open My site's homepage, Or the 100 people have looked at all the pages of my site, and the statistical system counts only 100 independent visitors.
What are the benefits of using an independent user as a statistic? Is it more accurate than IP?
IP is a concept that reflects the virtual address of the network, the independent user is a reflection of the actual users of the concept, each independent user relative to each IP, more accurately correspond to an actual browser. With independent users as a statistic, you can get a more accurate picture of how many visitors actually came to the corresponding page in unit time.
