The Internet-What is it?

According to dictionaries the definition is:

Internet

noun

1.
a global computer network providing a variety of information and communication facilities, consisting of interconnected networks using standardized communication protocols.


 

Technically, the Internet is a global system of connected computer networks. A network of networks, it allows computers to send each other small packets of information or data very quickly and over great distances.

When you use the internet to view a website your computer sends a request and recieves information in return, this is then displayed on your screen. The information you recieve is usually stored on a server that hosts the website.

 

The internet functions through the use of the Internet Protocol address (usually a series of numbers separated by full stops 19.61.2.1) and the Domain name system (the web address of a site http://www.nttn.co.uk). These allow the networked computers to be idendifed.


The internet is not centrally governed. The Internet Corporation for Assigned Names and Numbers (ICANN) directs the standardisation of protocols.




Traditional means of communication are being reshaped by the internet. Newspapers, books and other printed medium have become blogs and web feeds. Video calling using new Voice over Internet Protocol (VoIP) and media streaming

 

History
——–

Beginning in the 1960s networked computers began to emerge in the US. Protocols were developed through the 70s by a series of companies using ever more powerful computers.

The Internet started a rapid expansion to Europe and Australia in the 1980s and to Asia in the early 1990s. By the mid 1990s the introduction of more services to the internet like the World Wide Web and VoIP, bringing with them discussion forums, social networks and online shopping has, and continues to have, a great impact on societies across the globe.





The internet should not be confused with the World Wide Web.
The World Wide Web was invented by Tim Berners-Lee in 1991 and is just one of the services runnning on the internet. Other services include Email, file trtansfer, online games, remote computer control and newsgroups.

How to spot a scam email

Electronic mail is a very useful thing and can provide fast and effective means of communication. It allows us to store contacts and helps us organise our conversations. It has become an essential part of an extended internet experience giving us access to regularly updated information from subscriptions.

There is a dark side to the relatively free flow of information. Scammers have found ways to con you into parting with sensitive information that they can use to make money.  A method usually known as Phishing.

 

Stay ahead of the criminals, learn their tricks

Some sophisticated methods have been employed in recent years, for example targeting members of banks and building societies asking them to resend their details because of a computer error. Or ask to reset your password after entering your old one with your email address.

Never click on a link in an email unless you are expecting it.

The email may look authentic and that it is from a trusted source or the email link may take you to a web page that resembles the original, authentic one.

There is a simple way of staying ahead of the criminal online. Be aware of the risks and never give out your sensitive information to anyone requesting it unless you have instigated the process.

Be cautious if an unexpected email asks for your details.

You may receive trash mail or junk mail inadvertently by signing up to some websites as they will sell your details to advertising companies or automatically subscribe you to other websites without it being obvious. It is not a big problem but If you are concerned that this might happen read the terms and conditions before agreeing.

Its not just Email

This plague of confidence tricks does not only exist online and one should be careful giving out any information over the phone to strangers that call.

Letter mail can also cause problems as scams like this originated from this method. Promising winnings but the customer must pay money first in order to claim is just one example the criminals use to convince us of something that is clearly to good to be true.

Be wary if someone asks for payment before receipt.

A note about subscriptions

Email will enable you to subscribe to website newsletters and periodicals, deals and magazines. You can benefit a lot financially if you check your email for updates from subscriptions involving time limited offers. Sites like Groupon and Wowcher offer this type of service.

You can get bogged down with newsletters if you subscribe to everything but it is usually straight forward to unsubscribe from them. A link should be present at the bottom of the email or a link that will take you to a page that will let you do this.

Alternative ways to protect your email account

Always use strong passwords that include numbers and symbols and make it longer than 12 characters in length. For example use a password such as “myrabbitsears780£”

 

Use more than one email account. There are a lot of free email services to choose from so why limit yourself to just one. In some cases it can help to have more than one email account, it can be used to verify your other account and can help if you forget your password or account name.

Sainsburys, Tesco, Waitrose and Asda offer a click and collect service. Groceries can be pre-ordered and collected from the nominated store later. Ocado only exists online but does have free delivery most days after 10pm.
 


 
Reward cards or reward schemes are a good way to receive offers and special deals. All the supermarkets offer them and will mostly reward you with incentives to continue shopping with them, for example a bottle of wine free with next order or £10 off next order.
