答案是我自己写的不知道是否正确。因为这个试题正确与否决定我的去留。谁给个正确答案？

3题  应该是分辨率吧

4题 好像是C:\吧

我也觉得 第四错了 应该是  C：吧

今天知道答案了，3题是象素点。每个单位被成为点。
4题问的是绝对路径起始路径。而不是C:\

什么是提供IP地址和域名之间转换服务器
_____这道题很有麻痹性。提供IP地址到域名之前的转换！
DHCP：  
Short for Dynamic Host Configuration Protocol, a protocol for assigning dynamic IP addresses to devices on a network. With dynamic addressing, a device can have a different IP address every time it connects to the network. In some systems, the device's IP address can even change while it is still connected. DHCP also supports a mix of static and dynamic IP addresses.
Dynamic addressing simplifies network administration because the software keeps track of IP addresses rather than requiring an administrator to manage the task. This means that a new computer can be added to a network without the hassle of manually assigning it a unique IP address. Many ISPs use dynamic IP addressing for dial-up users.
DNS：(1) Short for Domain Name System (or Service or Server), an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name [url]www.example.com[/url] might translate to 198.105.232.4.
The DNS system is, in fact, its own network. If one DNS server doesn't know how to translate a particular domain name, it asks another one, and so on, until the correct IP address is returned.

(2) Short for digital nervous system, a term coined by Bill Gates to describe a network of personal computers that make it easier to obtain and understand information.
因此。觉得这倒题的答案应该是DNS服务器。

楼上的不用引用这么多e文把，看得我晕啊，，

1。应该是dns服务器

2，没看懂，应该是X
