Using Frontpage

What two steps are recommended in planning your site?

Establish the goal of the site first:
tips for creating a goal for your site:
  • Make sure you know who your audience is. For example, is your site intended for customers? employees? students? friends? family?
  • If you are making a site for your company, make sure the goal is specific and quantitative. After all, your boss will want to see results, and that usually means a specific dollar amount gained or number of labor hours saved.
  • Keep your goal simple. A couple of sentences or a short paragraph is enough. If your goal is too long, your site will end up looking like it's trying to do too much.
Sketching out a structure before creating a site in FrontPage and after you've sketched a map of your site, it's time to start sketching a common layout for each of your pages.

What is a web server?

A Web server is a computer that runs special serving software. That software "serves" HTML pages and associated files when requested by a client, such as a Web browser.

How do you put your website on a web server?

To put your site on a Web server, you publish it.Publishing generally means copying all of the files to a remote location on a server. In most cases, the remote location is either an HTTP path or an FTP path. The path you use depends on what technologies your server supports.

A server running FrontPage Server Extensions or SharePoint Services    If your Web server is running one of these technologies, you would publish your site to an HTTP location.

A server supporting FTP    FTP (the File Transfer Protocol) is another popular way to upload files to a remote server. If your server supports FTP, you would publish to an FTP location.A server supporting

WebDAV    Although not as common as the methods above, your server may support WebDAV (Web-based Distributed Authoring and Versioning). If this is the case, you would publish your site to an HTTP location.

FrontPage has two key functions – website design and …..?

Management tool

What are some commonly used file names for Home Pages accepted by servers?

html

What is FrontPage Metadata and which two folders contain these files?

FrontPage metadata is information about your FrontPage Web site that makes managing the site possible. The _vti_cnf folder contains information about every file, such as which links are within the file and who modified the file and when. The _vti_pvt folder stores all of the configuration information for the site.

There are two basic types of website can you create in FrontPage; what are they and how do they differ?

 a disk-based site is a FrontPage Web site you create on your local hard disk and then later publish to a Web server. A server-based site is one you create and work with directly on a Web server, without the extra step of publishing.

What is meant by a netbook? What is the 'cloud' in cloud computing?


Netbook is a small laptop(from 9 to 12 inches screen) usually with intel atom processor and intel gma graphic adapter made to be extremely portable, low on power usage(some can last for up to 9 hours or even more on the batteries), while their running performances are significantly slow and not designed to run games on.The cloud is a virtualization of resources that maintains and manages itself.


What applications does Google docs offer online?
Create basic documents, upolad your existing files, create spreadsheets and presentations online, Share and collaborate in real time, Safely store and organize your work, Control who can see your documents.

Why would you want you documents stored in the “cloud” (online)?
There are various advantages. First a major feature of cloud applications is that you can share them with colleagues or friends. You simply allow them access to the document instead of sending this document as an email attachment. Cloud computing can be done across various platforms. You don't have all those documents stored on your own computer, instead they are saved and stored "online", i.e. on the servers of the provider of the cloud application.
Advantages for students and teachers in google docs?
Enter Google Docs. students can create a spreadsheet in which you can share deadlines and assignment details (for example, whether it's a group or an individual task; if it requires write-ups, presentations, or just preparation). People can update them and edit and their work in group assignments in order to know how much work the other people have done.  You can use it to post to your blog, do writing assignments, type notes for reading assignments.  For teachers: For creating presentations to engage the students, share teaching methods or work that you are going to do. Upload the work for students if they lose the sheets or are away.

Which netbook, if any would suit your needs? Explain.
If I were to get a netbook i would like to get Dell Mini 10 (1012) because it is stylish,  impressive build quality, excellent screen, great keyboard and long battery life.

Internet Addresses

What is a URL?
The URL is the IP address of the website

The browser broke the URL into three parts:
  1. The protocol ("http")
  2. The server name ("www.howstuffworks.com")
  3. The file name ("web-server.htm")
What is an IP address and how is it related to a URL?
 each machine on the Internet is assigned a unique address called an IP addressThe browser communicated with a name server to translate the server name into an IP Address, which it uses to connect to the server machine.

   Given our school website's URL is http://www.mcauley.nsw.edu.au, what is our domain name and what protocol do you need to use to access the site?
domain name: mcauley
protocol: http://

    In the context of an IP address, what is an octet?
The four numbers in an IP address are called octets because they can have values between 0 and 255

What is meant by upload and download speed?
Uploading involves sending a copy of a file from a computer to a remote network connection.
Downloading involves the reception of a file that has been uploaded to a remote network.
Upload speed is usually slower than download speed because Internet providers have designed their system to optimize download speeds. This is because most Internet users spend more time downloading than uploading.

What are the units used to measure download speeds?
When talking about internet speed two units are often used - kbyte/s kbit/s

Why do different locations offer different download speeds? Hint: “bottleneck”
Because of the different connection such as dial up, wireless, ADSL connections, Cable connections

Key Terms- The internet and web design


  1. Define the term - Protocol
the set form in which data must be presented for handling by a particular computer configuration, esp in the transmission of information between different computer systems


2.  What are the following protocols used for?

TCP/IP- The TCP/IP suite of protocols is the set of protocols used to communicate across the internet. It is also widely used on many organizational networks due to its flexiblity and wide array of functionality provided.
http- http stands for (Hypertext transfer protocol) it is a method by which computers communicate webpages to one another
smtp-  SMTP (Simple Mail Transfer Protocol) is a protocol for sending email messages across the Internet
pop- POP is short for Post Office Protocol, a protocol used to retrieve e-mail from a mail server.
FTP- FTP stands for File Transfer Protocol. FTP is used to create a file server known as an FTP server which is a location created on the web that allows banks of files to be hosted/made available for download.
3.  What does GUI stand for?
Graphical user interface(GUI)

4. There are two methods of data transmission – serial and parallel. Explain the difference between them.

In parallel transmission, multiple bits (usually 8 bits or a byte/character) are sent simultaneously on different channels (wires, frequency channels) within the same cable, or radio path, and synchronized to a clock. Parallel devices have a wider data bus than serial devices and can therefore transfer data in words of one or more bytes at a time. In serial transmission, bits are sent sequentially on the same channel (wire) which reduces costs for wire but also slows the speed of transmission. Also, for serial transmission, some overhead time is needed since bits must be assembled and sent as a unit and then disassembled at the receiver.

5. Define the term “URL”. Explain the components that make up the url.

 Uniform Resource Locator (URL).
The first part is the protocol, which tells the web browser what sort of server it will be talking to in order to fetch the URL. In this example, the protocol is http.
  The second part of the URL is the fully qualified domain name of the website to connect to. This name identifies the website containing the page. The term "fully qualified domain name" refers to a complete website or other computer's name on the Internet.
The third part of the example URL is the path at which this particular web page is located on the web server. Similar to a filename, a path usually indicates where the web page is located within the web space of the website

6. In the context of data transmission, what is “error detection”?

Error detection is the detection of errors caused by noise or other impairments during transmission from the transmitter to the receiver

7. Why would error detection be important for the internet

It is important as if the error detection wasnt there you can get viruses because the error

8. Name and explain one common method of error detection.

Parity Check Method

Errors may occur in recording data on magnetic media due to bad tracks, sectors on the recording surface. Errors may also be caused by electrical disturbances during data transmission between two distant computers. It is thus necessary to device methods to guard against such errors. The main principle used for this purpose in coded data is the introduction of extra bits in the code to aid error detection. A common method is the use of parity check bit along with each character code to be transmitted. As a simple example of an error-detecting code, consider a code in which a single parity bit is appended to the data. The parity bit is chosen so that the number of 1 bits in the codeword or character code to be transmitted or recorded is even or odd.

9. What is HTML and explain why it is important

 HyperText Markup Language (HTML) is a computer language devised to allow website creation. These websites can then be viewed by anyone else connected to the Internet.

History of The internet

How did the internet originate?

The Internet as it exists today began as a military network that was used to transmit data over long distances. That evolved into a text exchange between educational institutions.
Who were the people most responsible for creating it?

 The Internet was invented in the United States during the late 1950s to the 1970s by a group of researchers and scientists at the newly formed Advanced Research Projects Agency (ARPA) after the former Soviet Union launched Sputnik

What system immediately preceded the internet? What was its purpose?
By 1989 many of the new community networks had joined the Electronic Networkers Association, which preceded the Internet Society as the association for network builders. To make it easier to communicate between networks

What is an IP packet? What is it comprised of?
The Internet Protocol (IP) is a protocol used for communicating data across a packet-switched internetwork using the Internet Protocol Suite.
 
All IP addresses are made up of four parts (quadrants) separated by dots, like this:
XXX.XXX.XXX.XXX
where each XXX can be any number between 0 and 255. If you know binary, you will understand that each of these numbers are stored in 8 bits (binary digits), and the number of possibilities you can have is 2 raised to the power of 8, which is 256 (0-255).
 
Examples of IP addresses are:
192.168.66.5
127.0.0.1

What does TCP stand for? How does TCP deal with lost IP packets?
transmission control protocol: a protocol developed for the internet to get data from one network device to another; "TCP uses a retransmission strategy to insure that data will not be lost in transmission"

Why do computer people like everything in letters?
Because it is easier to remember words than numbers
