Communicating on the Internet

Every day millions of people from around the world use the Internet to communicate.An email client can be either software or hardware. Microsoft outlook and Eudora are both software designed solely for the purpose of handling email. Gmail and hotmail are both web-based clients provided by a server. The email client also helps communicate with the email server and helps tell where the email is suppose to go. Once you tell where the email is suppose to go it can do the rest for you.
After you send the email the first step it does is your email client connects to a Simple Mail Transfer Protocol (SMTP) server for your email domain. The email client says who the email is from and who it is going to. The SMTP server then looks at the domain of the address that the email is being sent to and queries a Domain Name System (DNS) server to ask for the IP address of the domain in question. Once it has done that it then connects to that domain and passes the message along to its SMTP server. POP3 and IMAP are the two types of incoming mail servers. 
Instant messaging is an alternate to chat rooms, now you can do a lot more than just chatting. With IM, you can send and receive files, create chat rooms, and even send messages to and from a cell phone. Before you can instant message you have to download the client server. Once you connect to the server you can then sign up or log in to your account.  Because your user client has all the information it needs to send messages directly to your contacts’ clients, the server doesn’t need to be involved.

How the Internet works

What is the internet?
The internet was rooted in the 1960's from a US government research project run by Advanced Research Project Agency (ARPA). It is the worlds largest wide area network (WAN). The internet is made up of lots of smaller networks. In December of 2011 more than 2 billion people used the internet regularly. Everything you search and find goes through the internet. 

What is a protocol?
Protocols are the rules for how computers in a network communicate with each other. They control connection, communication and data transfer between two computing endpoints. ARPANET was the first network protocol in 1969. 

What is DNS?
DNS stands for Domain Name Service, this translates or resolves IP adresses. If we did not have DNS we would have no internet connection. DNS looks up a host name and returns an IP address or the other way around. Applications send a request called a DNS lookup to the computer’s DNS server.

  • Monitors are output devices
  • Many games and videos require high-definition (HD) monitors
  • Printers and scanners add value to systems 
  • Drives have changed considerably over 20 years
  • External drives give users more storage options
  • Tower cases have expansion bays    
  • Keyboard, Mouse, Monitor, Printer, Scanner, Storage drives, and game controllers/ joysticks. These are all peripherals 
  • Standard resolution: 1280 x 720 pixels (width x height)

Zapatopi

I do not think this a reliable website, it is not updated and it has many spelling and grammar errors. The whole point of the website is pointless. It does not give you many reasons as to why you should buy a AFDB which does not help. If you are like me and do not understand the reason why anyone would buy this, then you wouldnt want to see a website about AFDB's if it doesnt even explain why you should buy them. . It does not say who wrote the information or who even made the website. If you do not know who made the website and where the information is from it is hard to say it is a trusty website.

What is POIT?

POIT is where we learn the basics of software. POIT stands for principle of information technology. I think we are going to cover the basics of a computer. If you don't know how to use a computer or have a hard time on one this would help you. POIT is a part of the AOIT program it will help everyone to use computers better. I think this will help us give better presentations and help us be able to talk to a bigger group. I think it will help us when we job shadow of knowing what to do there. We will learn how to work with groups better and learn how to make decisions with other people and not just ourselves.


POIT will help us in the future, if we have a job that requires us to use a computer. Other people that have not taken this might not know as well. I think this will help everyone get a better look at how computers work and how we work them. Also i think we will go deeper into what the computer does. I think it will help us learn how to do a presentation better and to present. I think overall it will help everyone learn the basics of computers and the software.
