Welcome!
Most colleges and universities have computers available to students in labs or in the library. These are often hooked up to the Internet, and there is probably a knowledgeable person nearby to help you log on and answer any questions. If you want to set up your own personal computer system with Internet access, you'll need the following equipment:
The central processing unit (CPU) is the brain of the computer and its speed determines how fast the computer can process information. The two most important features to notice about the CPU are the type of processor, such as the Pentium processor, and its clock speed. The clock speed is measured in megahertz (MHz). A computer listed as a “300 MHz Pentium II” indicates that the processor is running at 300MHz. These two features determine, in large part, both the speed and the cost of a computer.
Random access memory (RAM) functions as a computer’s short-term memory, or working storage space. RAM is measured in megabytes (MB, millions of bytes) and is usually expandable. Modern software requires quite a bit of RAM to operate, especially if you want to use more than one software application at a time. An “insufficient memory” message probably means your computer is running out of RAM, and you’ll need to close some applications to continue. The amount of RAM on new computers is rapidly expanding, and most sold as of this writing have 32 or 64 MB. If you are thinking of buying an older used computer, consider upgrading its RAM to expand its capabilities.
The permanent long-term storage area on a computer is the hard disk drive.
This is where most of your software applications and documents live. The capacity
of modern hard drives is measured in gigabytes (GB, trillions of bytes). Software
these days takes up enormous space on hard drives, and if you plan to work
with video clips or sound files, you will need an especially large hard disk.
You can conserve hard disk space by storing some applications or files on
floppy diskettes or tapes, or by compressing files, but many people find this
inconvenient. If you are buying a new computer, you probably need at least
1 GB of hard disk storage.
Most computers sold now have a floppy drive for 3 1/2 inch diskettes. If
you anticipate using files stored on the older 5 1/4 inch diskettes, you can
have that drive added to the system. The CD-ROM drive allows you to access
data stored on CD-ROMs, which can store the data equivalent of 450 3 1/2 inch
diskettes. Since CD-ROMs are read-only, and you can’t store your own data
on them, you should buy a computer with both floppy and CD- ROM drives.
A modem is a piece of equipment that changes the information that a computer
works with into the kind of information that can be passed over the telephone
lines. It is what allows your computer to "talk" to other computers
around the world. It can be an external box or an internal card that is placed
in the CPU. Most new computers now come with built-in modems.
To use your modem, you will need a telephone line. You can use your regular
telephone line which will cause a busy signal when you are online, or you
can get a "dedicated line,”which is a separate phone line just for Internet
access. Universities often have banks of modems accessible through the same
number so when you call the university your call will be directed to the next
available modem.
Modems come in different speeds. The speed of a modem determines how quickly you can download or access information from the Internet. As of this writing, the most widely used speed is 56K, however, modems are continually getting faster, and there is now the option for high speed connections such as cable modems. If you are on campus, check to see if your dorm room is outfitted with Ethernet port so you can plug directly into the university's network without having to use a dial-up connection.
Most colleges and universities provide Internet access to their students
and faculty at an attractive cost, and if you have access to this you should
probably use it. If you need to hook up a computer to the Internet on your
own, you must go through an Internet Service Provider (ISP). ISPs are companies
that run the computers enabling you to get onto the Net; these computers are
called servers. It works like this: when you log on to the Net your modem
dials your ISP. When the modem is connected to the ISP, it actually connects
to the modem on their computer (the computer at the ISP is called the server).
The best- known ISPs are national ones like America Online and Compuserve.
But there are many smaller ISPs out there as well.
There are a few considerations to keep in mind in choosing among the many ISPs:
E-mail is a way of transmitting messages across a phone line to a specified other person's computer. To send or receive e-mail you must have a program called a mail browser (some common ones are Eudora and Microsoft Mail) and an e-mail account. When you send an e-mail to someone, you type in their e-mail address in the space provided. E-mail addresses consist of the individual user's name or identification, the @ symbol, and the name of their server and domain: username@servername.domainname.
After writing your message in the "body" of the e-mail, you can
send it. The message is transmitted to the recipient server which "sorts"
the mail and sends it to the individual's e-mail address.
E-mail is generally somewhat informal and not very lengthy. E-mail can be used for
everything from sending out memos, keeping up with friends and relatives, telecommuting,
and exchanging documents and files.
Here are a few things to keep in mind about using e-mail:
Since 1992, when the World Wide Web was first launched, it has
exploded into mainstream culture. For many people, the Internet has become
synonymous with the Web. The Web is a gold mine of information for psychology
students and faculty, and more is being added every day. As technology becomes
more sophisticated, Web sites are starting to feature animation, video, and
sound.
To get to the World Wide Web you have to have a computer program called a
Web browser. Some of the more well-known and popular Web browsers are Netscape
and Microsoft Internet Explorer. You can purchase a browser from a computer
store, get one from your ISP, or download one from the Web itself. To download
the latest version of Netscape for academic use, go to Netscape’s Home Page
(http://www.netscape.com). Once you
are logged on to the Internet, you simply click to open the browser and you
are ready to surf the Net.
You can analyze a Web site address to figure out who it belongs to and what they do.
A person or organization's Web site usually consists of many pages. The first page you
come to when you type in a URL is called the home page. This page usually contains a
menu for the entire site and lets you know something about the site's creators and
purpose. The home page contains links to other pages within that site, and often to other
sites of interest. With most browsers you can go back to a previous link by clicking a
button that says "Go Back.” You will not get "stuck" someplace you don't want to be, so don't be shy about exploring links.
Web sites can be developed by any person or organization on any topic. The amount of
information available on the Web today is staggering and continues to grow. You can
utilize the Web for general research, as an educational tool, as a shopping mall, to find a
long lost friend, get a new job, or answer most any question you might have; you are
limited only by your imagination.
Now that you have a basic idea of the workings of the WWW, how do you go about
finding Web sites that may interest you? A good starting point is to use one of the popular
directories on the Web called search engines. A search engine allows you to type in
keywords on the topic that you are interested in. It then retrieves any sites that contain
that word.
Some of the larger and more popular search engines are:
To use a search engine, type in one of the addresses listed above. When the home page for that site comes up you will notice a "search" box in which you can type a key word or phrase. The search engine will then bring up as a list of sites all the information that it has available on that topic. Sometimes you will need to narrow your search; for example, if you type "psychology," you may have hundreds or thousands of site listings returned. On the other hand, if you are too specific, you may not have any sites returned as a result of your inquiry. This does not necessarily mean that no sites exist.
Once you find a Web site you will want to return to in the future, you can "bookmark" it.
To bookmark a site, go to that site. After it has finished loading, choose "bookmark"
from your menu bar and your browser will instantly record the address to that site in your
bookmark folder. Anytime you want to return to that site, you simply open the bookmark
folder and click on the title of that Web site. Different ISPs offer different methods for
bookmarking sites. America Online, for example, uses a system called “favorite places”
that works similarly.
FTP stands for file transfer protocol. FTP sites are software repositories
from which you can download shareware software, demos, images, text, sound,
and anything else that can be transmitted via the Internet. You can access
FTP sites from the Web the same way you would enter any URL (FTP addresses
begin with ftp://). Most FTP sites support anonymous FTP, which means that
anyone can log on to the site with the user name “anonymous,” enter their
own e-mail address as the password, then download whatever files interest
them. If you download materials from FTP be sure to scan them with antiviral
software to be sure they are clean, or you could end up infecting your hard
drive with a nasty computer virus.
Before the World Wide Web, gopher was a popular way of storing information on the Internet. Gopher was developed at the University of Minnesota and is named for their mascot. Gopher sites are being retired as their contents are moved onto the Web, but many valuable ones still exist containing psychology-related information. Again, you can enter the URL for a gopher site (usually beginning gopher://) the same way you would for a Web site. You’ll see a text-only menu that you can navigate just like a Web site.
Telnet enables you to log on to another host computer to run one of its computers or to access information from it. You can telnet to other hosts from most Web browsers if you have telnet software configured to work with your browser.
Mailing lists (or listservs) are electronic mailing discussion groups that take place through e-mail. They are groups of people who "get together" online to discuss a specific topic. For psychology students, mailing lists offer a way to participate in lively discussions, stay up on current research, or find out answers to burning questions. There are mailing lists on nearly every topic imaginable. Here's how it works:
Newsgroups, like mailing lists, are a way of discussing topics over the Internet
with other people who share the same interests. However, newsgroups take place
on an entirely different "network" called Usenet.
Usenet is composed of thousands of discussion areas called newsgroups. Individual
comments that people make to one another on a newsgroup are called articles.
You "post an article" when you want to make a comment. The lines
of discussion within a newsgroup are called threads. To read the discussions
on any newsgroup you must have a software program called a newsreader.
Generally, your ISP will provide you with a newsreader program as part of
the software package. When you open the newsreader it should download any
new newsgroups that have been added. You can look through the entire list
and choose which newsgroups interest you. When you find one of interest, you
just open it up and begin reading the articles.
Newsgroup addresses are called hierarchies. Listed below are some of the
standard hierarchies with an example of each. There are many other categories,
some of which are from foreign countries.
alt - groups generally alternative in nature (e.g., alt.education.distance,
alt.alien.visitors) bionet - groups discussing biology and biological sciences
(e.g., bionet.general, bionet.immunology)
comp - groups discussing computer or computer science issues (e.g., comp.infosystems)
misc - groups that don't fit into other categories (e.g., misc.fitness, misc.jobs)
news - groups about Usenet itself (e.g., news.groups)
rec - groups discussing hobbies, sports, music, and art (e.g., rec.food, rec.humor)
sci - groups discussing subjects related to science and scientific research
(e.g., sci.med.nursing, sci.psychology)
soc - groups discussing social issues including politics, social programs,
etc. (e.g., soc.culture, soc.college)
talk - public debating forums on controversial issues (e.g., talk.abortion,
talk.religion)
Before you make a posting to a newsgroup, you may want to lurk for awhile,
that is, read the discussion without contributing your own posting. Lurking
will give you a sense of the kinds of postings that are appropriate for that
newsgroup and what the newsgroup culture is like.
Newsgroups may be frequented by people from all over the world, including some experts in the field. They can be a great source of current information and of community. For example, a person suffering from a relatively rare disorder may not know anyone else with the same problems and concerns on campus or in town, but he or she can frequent a newsgroup specifically for people with that disorder to learn about other peoples' experiences, the latest treatments, and just to commiserate. But, as always, be aware that not everything posted to a newsgroup is necessarily true; you must be a critical thinker.
Netiquette is simply the etiquette of the Internet. Because no one owns or
polices the Internet, it is especially important that all users take responsibility
for keeping communications civilized. Remember that the written communications
of the Internet cannot convey meanings by voice inflection or body language,
and it's easy to be misinterpreted.
Here are some good netiquette principles to keep in mind:
Emoticons are a fun way to express your feelings in electronic communication. They are a series of keystrokes and symbols that make a sideways picture. Emoticons can communicate to your reader that you are joking, disgusted, flirting, or sad--emotions that are otherwise hard to express in typewritten communication. Here are some examples:
:-) this is the most common emoticon, known as a "smiley"
;-) here is the smiley, winking
:-p here is the smiley, sticking out it's tongue
(:^) here is a bald smiley
:-( this is a sad smiley
