The world wide web


In this video, I’m going to talk a little
bit about the World Wide Web and how to connect to it. Most people on the Internet used to
be either a consumer or a creator. But things are changing so people can be both. Think
of Facebook, you are both. You read what other people put up, and you put up your own information
as well. Let’s talk a little bit about the difference between the web and the Internet.
The Internet, and yes it is a capital I, because there is only one Internet, so it is a proper
noun. It is the global network of interconnected computers. This is different from the web.
The Internet is all of the hardware tying everyone together, all of the physical connections,
the computers, the servers, the actual T1 lines, all the lines connecting everything.
The World Wide Web, or Web for short, is a way of accessing the Internet. It uses HTTP,
which is Hyper Text Transfer Protocol. The Web consists of all of the interconnected
pages, all of the content on the Web. You are going to need a few things to be able
to get online. First, you will need an Internet Service Provider. (ISP) That is the company
that you pay to provide you access to the Internet. Many of these Internet Service Providers
are telephone companies, or work over telephone wires, though they can also be cable companies,
or other telecommunications companies. Originally, it was a separate company, like AOL, Prodigy,
Compuserve, but today the big players are AT &T, Comcast, Charter, there are other types
of Internet you can get as well. Let’s look at, and talk about connection speeds.
Generally, you want the fastest Internet that you can get for the lowest possible price.
That’s your best buy. Generally, that is going to be cable. Cable is extremely fast, it has
downloads of 25 to 100 megabits per second, the higher the number the better. It has upload
speeds of 2-8 megabits per second. It will cost, in most areas, around 40 to 60 dollars
per month. (2013) Often you can choose how fast you are paying for, because you pay more
for faster access. You will notice on the right hand side of the screen, I have a couple
of sources I used when doing research on the connection speeds. DSL is hosted over the
traditional copper wires, probably already coming into your house, often sold by AT&T
or another local phone company. Download speeds are typically 1.5 to 15 megabits per second.
Upload speeds are 128 kilobytes per second, which is less than a megabyte, to 1.0 Mbps.
The cost is very similar to cable. You can also use a wireless Internet connection.
You can do that by searching the web on your phone, a tablet that is connected to the service
provider for your phone, you can use your phone as a hot spot or you can buy a separate
hot spot or adapter for your laptop and other devices. That’s typically very fast, with
4G you can get up to 50 mbps which is comparable to some of the lower speeds of cable and faster
than DSL. It can be a little pricey. Prices vary, but it can be a little pricey for a
month, and many of them have limits on how much bandwidth you are allowed to use, per
month or you pay by the amount that you are using. You can also use wireless line of site
radio signals, those are usually coming from water towers and broadcasting to dishes on
the top of your house, or using antennas to catch the signal. That’s typically used in
your more rural areas. My parents live on a farm, they can’t get DSL or cable, this
is what they do to get a reasonably fast Internet connection for a fair price. Satalite is for
extremely rural areas, it’s slow and expensive, so it is generally not a good choice.
What do you need to set up an Internet connection for your house? This is assuming that you are putting together
a wifi spot or network in your home. First you are going to get your ISP, you are going
to pay for your service so that there is service coming to your house. Once it gets into your
house, you need some sort of modem. Modem stands for modulator Demodulator, and it used
to be used with the old dial up phone lines where it would change sound waves into 0 1
01 01 – binary code. That is what the modem did. Now it is going to take whatever signal
is coming into the house, and it is going to come into your modem, Then you may have
one unit combining a modem and a router, or you may connect your modem to your router.
What your router does is it splits the signal and allows multiple devices to use it. Typically,
on one of today’s routers you will have five connections in the back and almost unlimited
connections for wireless connectivity. Then on whatever device you are using, you will
need some sort of Network Interface Card (NIC) that is usually integrated, not something
that you buy, it is usually already in your device, and what that does is it actually
listens for or receives the signal coming from your router. Then of course you will
need a computer or the device that you are going to connect to the Internet.
For your home security, it is very important to set up your home router with some basic
security. Several years ago, I went to a conference that had somebody from the FBI speaking at
the conference about wireless networks. He was talking about having gone into a home
and arrested somebody under suspicion of downloading child porn, but when they checked the person’s
computers all of his computers were clean. What had happened was that his next door neighbor,
he was in an apartment, and his signal was very clear to the neighbor next door, he hadn’t
enabled password protection, and his neighbor was using his wireless network to steal his
Internet connection. Make sure to password protect your network, you don’t want somebody
outside of your home getting access to your files or your network. When you buy a router,
you do typically have an option of buying a slightly higher level router that will allow
you to offer guest access. If you have kids living in your home, I recommend this, because
I don’t want outside people having access to my files, but I don’t mind when my kids
have friends over, letting them have access to the Internet. I have a guest password that
gives them internet access only, but doesn’t give them access to my shared resources. Now
when you are setting up your network, you want to make sure to have fundamental security.
At a very minimum, password protect your network. I prefer to go one higher level at minimum.
Don’t broadcast your network ID. Many of your routers have the option to not broadcast so
that if you have a mobile device and you bring up the available networks, it won’t show up.
You have to type in the name of the network. The goal of security is to be harder to break
into than the person next door. If there are five visible networks, and your network is
not visible, people are unlikely to look for the network that they can’t see, they are
more likely to try and break into one that they can see. If you need to be more secure than that, you
can limit the specific devices that can connect by their MAC address. Your best bet is to
be completely wired, but that is not very reasonable in today’s times because it wouldn’t
work with kindle and other mobile devices. Lets talk about browsers. I’m concerned that
when I teach this class, people don’t know the difference between a browser and an Internet
Service Provider. Now when AOL and Compuserve were the primary ways to get online that was
very understandable, because AOL was a bunch of things in one. They had their own browser,
even though AOLwas the company that you would pay 19.95 a month to get online. Today, our
browsers are Internet Explorer, Firefox, Chrome, Opera and Safari. Those are the 5 big ones.
They translate the content of the programmed web page into something visible that you can
click on or work with, view and interact with. They also have additional tools, pop up blockers,
spell checkers, and can manage how you use the Internet by saving passwords, by saving
your favorites, by creating shortcuts, so there is some additional features in each
one. They usually have tabbed browsing and spell check, things like that.My first link
here is a review of the top ten browsers. It will take a second, there we go. This is
a good review of the top ten browsers, and it compares them by speed, by feature set,
by security, by ease of use, by help and support. Right now Chrome is considered the best, and
it is also the most commonly used. Firefox is considered second best, it is the second
most commonly used. Then you have Internet Explorer. Now Opera is rated higher than Safari,
but Safari gets slightly more use than opera. When you look at the different tools and compatiblity
it is interesting to note that Internet Explorer, by Microsoft, does not run on a Mac. These
are things that you can look for in picking which browser you want to use. Now you will also, on my second link, which
takes you to the W3Schools.com, I love this site, I use this site a lot and this site
has browser statistics and trends. As a designer, I Iook at the trends and try to decide what
browsers I should design for, where I need to test for.by what is commonly in use. It
is important to notice that over time things have changed. Chrome hasn’t always existed,
in fact we saw chrome come on the scene in about 2008 and it took it a while to hit the
majority, but this tells you sort of what is being used currently. Which, if you are
a designer, is important. There are several programming languages that
make up the Internet. The very base core of a static web page, at the very minimum, you
need an HTML page. The information here on the left hand side shows the history of how
HTML has evolved. It started with SGML, which is standard generalized markup language, the
formatting language behind word processing engines, like Word or Word Perfect. That’s
where the hyper-text markup language, HTML, evolved from. It evolved from word processing
software. It has had several versions. Years ago, in 1997 when I was taking my first college
class in programming for the Internet, I was using a book on HTML1.0. It had a cheat sheet
where I could pull out all of the commands on one side of one page. That did not describe
them all, and everything that they could do, but still it was a very small set of instructions,
so you had a lot of limits to the formatting that you could do on the Internet. as time
has gone on, different features have been added and HTML has gotten more powerful. In
the early 2000, there was a move to go away from HTML and to XHTML. That was because the
thought was that you could make it extensible, something that you could specify your own
tags for. It was combining two languages: XML, which was a data transfer language used
to move information from a database to another database, it can be used by all programming
languages, and HTML.There was another group that did not agree with the direction that
XHTMLwas going. They kept working on the HTML5 specification. It was a tossup for a while
to see which one was going to win. HTML 5 appears very strongly to have won, the specification
is being used, and it has a lot of really cool features. You are seeing used across
most of the modern browsers, even though the personification has not been fully approved
by the W3C, the world wide web consortium. They are the standards body for the Internet. CSS works hand in hand with HTML, HTML was
supposed to be used for the informational content on your page. CSS is supposed to be
used for styling your page, for setting your fonts, your colors, your page layout. The
nice thing is if you do design properly, according to the standards, you can write the HTML once
and you can have a different style sheet for each type of device or screen size that might
be accessing your page. You can get a completely different layout and look for a phone, a tablet,
a computer, a wide screen tv. It lets you have total control, you can also have a style
sheet just for printing. All formatting should be done in CSS, and all content should be
done in HTML. That is not necessarily a given, because in the early versions of HTML you
could do formatting. The third language that gets written in your
actual HTML document, sometimes – you can call it externally as well, i s JavaScript.
JavaScript allows interactivity, it lets you do some simple things where it can actually
interact with the user. It can work with forms for tracking form validation, it can change
the color of your page, it can be used for simple animation. It is typed right into the
HTML document, or a similar document that is on your server, in the same folder or at
least on your server in the same site. All of the programming is run by your browser,
the HTML, the CSS, the JavaScript, that is all interpreted by :Chrome, firefox, one of
the browsers. That makes it a client side programming language, because it’s interpreted
by software on the User’s computer instead of running on the web server. When you create a Web Application, it is much
more complicated then that. Typically you will have some sort of database that is hosting
information, then you will have a middle layer that is a programming language that passes
information back and forth from the database on the web server, to the clients computer,
and then a user interface which is created in HTML, with CSS and JavaScript. So an example
of a Web application would be something like Facebook. All of the data is stored in a giant
database, there is a programming language that takes that data back and forth from the
server and user’s device, and then there is the interface, which is done in HTML. When you make web pages, back in the 1990’s
there was really limited formatting so webpages were kind of either plain or really ugly,
depending on who designed them. Most web pages back in the mid to late 1990’s were created
by programmers, because you had to hand code to be able to make a web page. In the late
1990s WYSIWYG (What you see is what you get) editors became commonplace. Things like Dreamweaver,
Go Live, and other software evolved to make designing web sites something that you could
do visually, and interactively, without having to know how to program, we have also gone,
in the world of web development from having somebody who did it all, a webmaster, to getting
specializations, one of the primary specializations is a web designer. They do the layout, pick
the colors, pick the fonts, and that is done typically in Photoshop or a similar program.
The web designer will hand that off to a web developer, who is going to create the code,
run the database, and do all of the back end work, there is a much higher demand for web
developers than there is for web designers. Web developers are paid about twice as much.
A good web designer is making about 40 -45 thousand dollars a year, a good web developer
can easily make twice that.
