1: As for how it works, I believe once you type in a domain name and hit “enter” to send it a message is sent to the nearest or possibly the main DNS server. I am not really sure if there is a main DNS server that links them all together or if they are all just equally linked and communicate with each other. Once the message gets to the DNS server, the DNS server searches through all the DNS servers in order to find the IP address that is associated with that domain name. The DNS server sends the IP address to your computer. Your computer takes that IP address and searches the Internet for it and connects you to the website that has that IP address. I believe that is basically the whole process that is going on.

2:DNS stands for Domain Name System.  It is an IP address to computer name translation.  A computer can reached by typing in the PC name rather than typing in the IP address, though it can still be reached through the IP address.  When a computer name is typed into a we browser bar it goes out to find the DNS server that is hosting the name.  Once it is found then the name is associated with the IP address.  Users will benefit from DNS because it is much easier to type in the name of store, for example, than it is to try and remember the IP address.  Something like www.bestbuy.com will take you to the hosted website and is a much quicker way of finding what you need.  

 

3:SNMP is a protocol for network management. What are the basic components of SNMP? What are the benefits of the functions provided by SNMP? SNMP uses the UDP protocol for transport. Why was UDP chosen over TCP?

 

4:Discuss the assigned readings and Internet research, concerning the differences between the graphic formats of JPEG, GIF, and PNG? Provide an example of when you would use each.

 

5:I agree about Adobe Flash, I have noticed that most of the browsers I use automatically block the Adobe Flash Plug in and it has to be manually activated to view all of the content on the page I am looking at. To stay of the safe side I typically avoid activating the plug in unless I am a regular user of the specific web page. The company itself has confirmed a major vulnerability in all versions of their software that can allow hackers to crash or take control of a PC. This type of problem could steer users away from your web page as they would not want to put their computer at unnecessary risk.

 

6:I also enjoyed this article. It is a good resource to determine if you are meeting the intended goals of your website. Utilizing the checklist is a basic yet helpful reminder of all the requirements and suggestions for a strong web presence. The first item on the checklist is website compatibility which is an essential consideration for developers. Many users have a specific browser that they prefer for Internet use and all of the major browsers have different compatibility requirements. Seamless use of the website across each browser is very important. The final question on the check list was is your web site usable? This highlights the need for user-friendly design and functions. The article mentions that it is not ourselves that the sight is designed for but for the visitors of the website.
