Operating Systems

1. An operating system is a type of software:

True: It can be downloaded to a computer, and is a set of instructions on how the computer will run, but can also be called hardware.

2. Operating systems control the loading of software applications onto a computer:

True: because the operating system will download the needed software applications for that systems software.

3. All operating systems are for user preference, allowing you customize your computer:

True: You can change them all within the Operating System

4. An operating system prioritizes the task that the CPU does

True: it will organize the tasks in priority order.

5. The following devices have an operating system: Apple iPod, Dell Laptop, and Nintendo Wii

True: They are all complex computer devices.

Communicating on the Internet

Email Clients and Servers

Email uses client/server technology. If you have ever sent or received an email, then you have used an email client. An email client can be hardware or software based. The client is what allows you to preform tasks such as reading and sending emails, along with downloading attachments. Email client is what communicates with email servers, which are in charge of getting the email, where it is supposed to go.

How Email is Delivered over the Internet

The first step to delivering the email is that your email client connects to a Simple Mail Transfer Protocol (SMTP) server for your email domain. This is telling the email where to go. 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 a question. There are two types of incoming-mail servers, POP3 and IMP, the biggest difference between the two is that when you get an incoming email from a POP3 server, you download it from the server onto the computer. On IMP server, the email stays on the server until you delete it.

How Instant Messaging Works

Instant messaging also known as IM has been around since the early 1990's. I became an alternative to chat rooms, this still allowed people to chat over the Internet in real time. Using IM, you can send and receive files, create chat room, and send messages to and from a cell phone. To use IM, you will need to download the client software needed for whatever service you want to use. From there you make an account and log in. The client, when logged in will send your IP address to all your contacts that are online, from there you are free to IM whatever you want. Some of the popular IM's are AOL Instant Messenger, Yahoo! Messenger, and Apple's iChat. 

How the Internet Works

What is the internet?
is the world's largest wide area network. The internet is made up of millions of smaller networks. Everything you find online comes through the Internet as i connects several networks together. Originally the internet was created as a research project for the government, so they could link all their information between headquarters. Back in the 1990's not many people had computers, so there wasn't a great demand for the Internet.


What is a protocol?
rules for how computers in a network communicate with each other. They control or enable the connection, communication, and data transfer between two computing endpoints. The protocol is like a guideline, with how to control the Internet. It has a list of do's and don't's for the Internet to follow, so it can successfully connect several networks. Protocol is the correct way to connect computers through multiple networks.

What is DNS?
DNS looks up the IP address for the host name of a website.DNS is like a phone book for the Internet; it looks up a host name and returns an IP address, or vice versa. When you type www.cnn.com into a web browser, the application has to go to a DNS server to find the IP address associated with www.cnn.com.

Learning About Peripherals

Learning About Peripherals Notes:

• Peripherals are the devices used for a computers input, and output.
• Peripherals are devices like, a mouse, keyboard, monitor, printer, and USB.
• A keyboard reports a key press into a software program, that reads the keystrokes.
• Keyboards also give commands to the operating system of a computer. (ex. Ctrl-Alt-Delete combo brings up a task window.)
• There are different types of mice, like optical, or laser technology.
• Monitors are output devices, and there are two types of monitors, LCD and a CRT monitor.
• High-definition (HD) monitors have better resolution, which means a clearer picture.
• A pixel, which is a picture element, is the smallest colored dot that can be displayed on the screen. More pixels= more detail.
• Standard resolution is usually 1280 x 720 pixels (Width x height).
• printers and scanners add value to systems (ex. Multifunction, scanner, and inkjet).
• There are a lot of drives, and they have changed over the last 20 years (3 1/2 in. floppy drive, CD-ROM drive, DVD drive, and Blu-ray drive).
• External Drives give users more storage options, (ex. Combo Hard Drive, DVD with laser light, USB drive).
• Tower cases have expansion bays, they usually have at least one bay for an optical drive, such as a DVD, or Blu-ray drive. Different sizes and types can be loaded into the same tower case.
• The peripherals needed for the dream computer projects: Keyboard, mouse, monitor, printer, scanner, storage drives, and game controllers/ joysticks.

Zapatopi

http://zapatopi.net/afdb/ is not a valid website.

For starters everything about the web page makes it a valid web site, it lists the author: Lyle Zapato, it also has the created and up dated dates. The up dated date was in 2008, so it is kinda out of date. The web site does not contain any spelling errors, that I could find. Even though all of that makes it a valid website, the major part that throws the whole website off, is what it is about. It is about a aluminum Head cover to protect you from mind control, which in my opinion is just crazy, so the information is not trust worthy. Lyle is very biased, and has no way to verify his information, so you would have to assume its right, but the real answer is no, don't believe him.
