Path of an e-mail
write the e-mail and then sends it off to an e-mail address (e.g. email@example.com)
the message is sent from user 1ís computer to the mail server via SMTP (simple
mail transfer protocol) it is then sent to the recipients ISPís (Internet
service provider) mail server, when the recipient requests there mail from there
ISPís mail server it is download to there computer via POP (Post office
mail is originally sent to your ISPís mail server, the address is looked at
this determines which mail server the mail gets sent too. This is done by a DNS
(Domain name server) this server looks at the address and breaks it up, and then
finds the IP (internet protocol address) address of it, with is like the
telephone number for that computer on the Internet. Once it has made contact with the recipients mail server, it
has a short ďconversationĒ including information bout the sender and who it
is to be received by and then the message is sent the connection is closed down
and the transfer of the e-mail is complete.
E-Mail client: -
individuals use e-mail as a way of keeping on contact with family member or for
contacting company, companies may contact suppliers by e-mail and also run a
customer support service through e-mail. E-mail allows individual and business
to send and receive files send as attachments these file may contain photos of
business project or of special occasion from family members.
are still many today who do not use e-mail this may be due to many reason. An
example of a group of people who donít use e-mail would be the older
generation, this is because the idea of e-mail is new, and they have been shown
how to use the new technology. There are also a large number of people who
donít use an e-mail system because they do not have access to a computer; it
is impossible to access your e-mail without access to a computer.
is possible with computer to pick up your e-mail whenever you want to from where
ever you want too. This is because the mail servers and always turned on so when
you log on to your e-mail anywhere in the world. The client on your local
machine requests from you ISPís mail server your e-mails and downloads them.
There are many different types of e-mail clients there are stand-alone programs
like Microsoft Outlook express or Microsoft outlook, it is also possible to
access your e-mail from the internet if your ISP supports web mail, example of web mail
facilities are hotmail, gmail and yahoo.
are many problems which can occur with the e-mail system, the e-mail system
relies on many computer to send just one piece of mail, so if one of those
computers isnít working properly or malfunctions then no mail will get
feel that e-mail is slowly replacing the letter however I feel the telephone
call has been given a new leash of life by the latest developments in video
Advantages and disadvantages of E-Mail
Advantages and disadvantages of tradition mail
can see both systems have there advantages and there disadvantages, and both
systems are extremely useful and both still valid in todayís society however
with the idea of a paperless office and the increasing cost of sending mail. I
feel that sending e-mail will grow further especially as computers continue to
take off and are more access to everyone.
What is the difference between web-based e-mail and client e-mail services?
difference between web-based e-mail and client e-mail is that web-based is
exactly what is says, it is web based you run/access it from your Internet
browser and is not installed on your local machine. Client e-mail is outlook
express and similar software. This software has to be installed on the machine
locally which mean for example if you use a third party client e.g. AOL e-mail
reader then you must have that installed on every computer you may want to
retrieve your e-mails off. Many ISPís offer a client e-mail service along with
a web-based version.
messaging is a system of talking with people in real time. This means that you
can have a normal conversation with someone, in the same amount of time, instead
of having to wait for him or her to pick up and read the e-mail you can just
talk to people like you would if you were talking to them face-to-face.
messaging is used by a wide age range however it is mainly used the 13 + age
range, the teenagers. Instant messaging is used by teenagers for everything from
homework help to general socialising, so other used are IM has and is used for
dating, business meetings and also with the new technology like video
conferencing it is really taking off in businesses and also as way of teaching.
Instant messaging is an emerging technology and is still growing rapidly;
this is because it is an extremely easy and safe way to socialise. One big
problem is today teenagers congregating on the street, and teens get complained
at for this. Youth clubs are closing now so they are looking for a new way to
talk with out having to be out on the streets. Also instant messaging is safer
then chat rooms because in chat room any one can talk to you were as on instant
messenger you can only talk to people you have added. In chat rooms you donít
allows know exactly whom you are talking too, which causes concern about the
safety of chat rooms which has only added to the popularity of the instant
Instant messenger is also used in technical support an example is in
Linksys a company which makes network equipment offers real time support in the
for of an instant messenger allowing you to talk to a representative of Linksys
who will help you solve your problem, this I feel is a very good Idea because
sitting talking to people on the phone while trying to operate a computer at the
same time is often difficult were as typing into instant messenger which on the
computer is easier and also more convenient. It is an extremely good idea if you
have dialup Internet being as you canít work on a dialup connection while on
There are many instant messaging services around however there do seem to
be a few clear leaders in the race. These leaders are AOL, MSN messenger and
Yahoo messenger. MSN messenger offer a few additional service as well as
messaging, it allows you to set up video conferencing free of charge and also
get access to MySpace, an area of web space which you can personalise to suit
your tastes. I think these messenger are more populate because they offer a wide
range feature as well a just talking, you can play games, hold audio
conversations, share applications and also ask a friend on your contact list for
assistance with a problem.
What is IM 'phishing'?
Phishing by definition is: -
In computing, phishing (also known as carding and spoofing) is a form of social engineering, characterised by attempts to fraudulently acquire sensitive information, such as passwords and credit card details, by masquerading as a trustworthy person or business in an apparently official electronic communication, such as an email or an instant message. The term phishing arises from the use of increasingly sophisticated lures to "fish" for users' financial information and passwords.
Source :- http://en.wikipedia.org/
Phishing is a problem with the e-mail and IM systems, in
E-mail it is normally discarded with the spam but with IM because it is
controlled by a human is more dangerous, a person could befriend you on the
internet extract sensitive information out about you and use it to acquire
money, from credit card companies or load companies on the internet.
What is usenet?
Usenet was a bulletin board set up in around 1979 at the duke university. It
was similar to a forum where members could post comments and others could add to
them providing they have access to the internet. The idea and popularity of newsgroup
or forums have grown over the past years. An there are now thousands of forums
available for everyone to view on all kinds on topics from computer to cars.
Many of the forums, which exist today, run from a php script, the forums
have a log on and password, after logging onto the forum you can view other
peoples post and add your own comments. Many modern forums also offer other
features such as search wizards and personal messaging. Personal messaging on
forums is like sending e-mail to some one but it is totally internal and is
handle by the script and not mail server.
Many different types of people use newsgroup and there are many reasons
for using them, newsgroups can be used for personal or for business use. There
are newsgroups, which will give you information about your hobby or personal
information. Another use for newsgroups is for technical support, you can post a
question you would like answering and if another member knows the answer or can
tell you where to find the answer them they will. An example of this is the www.computing.net.
newsgroups you can share experience so others can learn, in some ways newsgroup
are like textbooks on any subject you can always find an answer to your
the main benefits that people get from using newsgroups is learning from others.
You can ask people like yourself who share the same interests a question and
they will try and help you from there own experience and knowledge, it is an
unlimited resource as it is constantly expanding as people add to it. So you can
always find an answer. Another benefit of newsgroups is you get to meet people
who share the same interests as you and help each other with problems you may be
having or have had.
also exist through the use of e-mail, or a mailing list. What would happen is
you will sign up to the newsgroup and then you will start receiving e-mail from
the group with information and questions on. You can send e-mail to this mail
group and the e-mail will go to everyone in that group, similar to sending an
e-mail to several people at the same time, however doing this through a
newsgroup is safer because not one can find your e-mail address as the mail
isnít sent directly to you it is sent to the group. An example of this is ďvbcodehome@googlegroups.comĒ
this is a newsgroup about visual basic programming this particular newsgroup is
hosted by google. As you can see this doesnít show a list of member or the
member who sent the e-mail, it just appears and says it is from firstname.lastname@example.org.
So it is more secure.
It is possible to use newsgroups for the purpose of research. In
modern forum it is possible to set up a post which acts as a poll or you could
post a survey and ask people to send there answers to your e-mail address. And
in newsgroups were you send e-mail to the group you could post a list of
questions and ask people to reply to the group, so it is possible to conduct
research by the use of newsgroups however you must look at the integrity of the
data because people could answer anything, and also if you are asking questions
bout computer knowledge on a computer forum then you arenít getting an
un-biased view of people. To use newsgroup for collecting you must really
collect information from a group of newsgroups so to get an un-biased view.
definition of online conferencing is: -
Web conferencing is used to hold group meetings or
live presentations over the Internet. In the early years of the internet, the
terms "web conferencing" and "computer conferencing" were
often used to refer to group discussions conducted within a message board (via
posted text messages), but the term has evolved to refer specifically to
"live" or "synchronous" meetings, while the posted message
variety of discussion is called a "forum", "message board",
or "bulletin board".
conferencing can be used by anyone from individuals to large multinational
companies; it allows you to use multimedia to demonstrate something or to talk
to people over the Internet.
conferencing can also be used by educational establishments to enhance
distance-learning programs. With can be done using video conferencing where a
computer is used to connect the lecturerís home or work place where the lesson
can then be delivered. This has been made possible over the last few years but
the introduction of faster Internet connection.
simple form of online conferencing is video conferencing, which is provided by
instant messaging services such as MSN. The latest version of MSN messenger
enabled you to hold video conversation, which consists of video and audio
streaming. This enables real-time
conversation to take place as if you actually sitting with the person you are
can use online conferencing in many different way, they can use it for meetings,
presenting ideas or for training purposes.
is possible with a system like breeze to set up business meetings with multiple
people from around the world, so you could meet with a person in the states and
a person in Europe and all sit in your own offices. This is great on the
business side because it mean the business doesnít have to pay for
accommodation abroad and you can continue to work once the conference has
finished. Again with a system like breeze you can set up demonstrations of
programs or tutorials, and record your commentary over the top so you can show
people how to do something and explain at the same time.
This is a new way of online learning and is used in business because it
allows the company who developed the software to show a group of people all at
the same time and they can all be in different locations.
online conferencing you can create presentations to sell a product or service,
this enhances your company because anyone can watch the presentation whenever
they want to and learn about the product.
feel online conferencing had the potential to take over from traditional
conferencing. This is because it is convenient as you can do it form the comfort
of your office, and donít have to travel. It is also less expensive (apart
from the initial set-up cost) because if your business has a client in for
example Japan it would be cheaper to set-up a video conference then send a
representative over there. However the downside of online conferencing is it
looses the personal touch. If you were going to purchase something would you
rather talk to a salesman in person or talk to a salesman on the Internet? So I
feel that it will become even more popular it is removing the personal touch out
of business, which some clients may not go for.
short for weblog. A Blog is a list of articles, which shows the authors opinions
and view about a subject. They are normally updated manually however with the
creation of software to automate the maintenance and update of the blog.
Blog can have several uses from a personal blog like a diary to a
corporate blog showing development of the company over a period of time maybe a
month or so. The time scale, which
they are based over, can change so for example a blog could have an entry made
into it everyday or just maybe once every few months. Some of these sites are
made interactive like forums so others can leave their opinions and suggests,
while others are there only to read. Some of the popular blogs have there own
RSS feed which means people can be notified when it is update and send a brief
cut down snippet of the text to you.
function of blogging is available by many companies free of charge, and each
offers slightly different things. From different amounts of space on the web
servers to free register domain with it.
people use blogs and can be used to show different things, for example a blog
maybe a personal like a diary or it may be fro a computer showing company
development. Some personal blogs may show just and ordinary diary or it may show
the track of a campaign, which that are involved with, or there thought and
feelings about something, which is happening to them. A companies blog may show
the develop of a project, like a journal. Or may show the development of the
company as a whole. The benefits of writing blogs are to share your experiences
with others. In companies a blog, which show the development of the company, may
help sell your product/services or even help your company on the stock market.
If a trader can see that your company is growing and that you have future plan
and Ideas it may just tip the balance for them purchasing your shares instead of
are advantages to blogging as well as disadvantages. One advantage is you can
share experiences with people and let them learn from mistake you maybe have
made, if you are a company then blogging is a good way of showing development
and offer publicity to your company. However on the downside, with personal
blogs, you are sharing your life with other people and it is possible form them
to abuse the information you are telling them. Also with personal blogs you are
telling people your opinions and view about things, which they may not always
agree with. So you have the possibility of getting comment added to your blog,
which arenít what you want.
