Online Transactions

Online transaction is transaction through the Internet. Examples include buying an airline ticket, paying your monthly household bills, buying and selling online, etc.

For buying and selling (goods and services) online, there are two types of transactions –
(1) buying/selling through a service provider (e.g. eBay, Yahoo, etc) and (2) buying/selling through the Internet, with the seller (a Company) having its own dedicated web site.

In buying or selling, it can be through a fixed price or through an auction bidding (with a closing date). If you are the seller, you need to provide details of your offer. This may includes starting price (if by auction) or fixed price and state all other fees applicable (e.g. posting and packing fees, etc). As a buyer, you need to satisfy yourself all costs applicable and to ensure that you will get your good/service after the money is handed over to the seller.

If you are new to this way of online buying or selling, I would suggest you start with the simplest way (sell/buy locally) – and that is for the buyer to meet up with the seller. The buyer examine the goods and if satisfied, pay directly cash to the seller. This we termed it “Cash on Delivery” (C.O.D.). 

If you are doing some other forms of online transactions which requires you to enter sensitive information (like your visa card details) – please consider the following:

a) The computer you are using to perform the transactions – is it free of viruses and spywares, phishing, etc.?
b) Are you sure you are transacting with the genuine or right Company – have you typed the correct URL (web address) of the Company.
c) Have you accidentally gone to an imitation or fake site? (a web site that pretend to be the real one and with the aim of “stealing” your sensitive information – we called this phishing).
d) In Internet transactions, be careful also of fake emails that pretends to be from someone you know or someone you can trust and asking for your confidential information. Never trust any email that give you or inform you something that is too good to be true. Are you that lucky to have won something and have to be told just by an email?
e) Are you transacting on a secured web site provided by the Company? All reputable Company will provide a secured web site for you to transact with.


Know your Mouse

An Optical Cable Mouse

A PC mouse is an input device. There are two types of mouse, cable or wireless. Basically, the mouse has three features, namely (1) the Left button (左边), (2) the Right button (右边) and (3) the scrolling wheel . The Right button when pressed once (Right click) – it provides us with a “menu” of choices and when the Left button is pressed once (Left click) – it confirms the choice we have selected. Pushing the scrolling wheel up or down will “scroll” the page up or down respectively. Holding down the Left button “continuously” will perform a “drag” function.

Peripheral Equipment for Computers

Look closely at any computer, you will observe that there are many types of peripheral equipment or accessories that can be connected to it to perform a variety of tasks.  Besides the standard mouse and keyboard man/machine interface, other types of accessories are also possible to connect to the computer.  The most common is the USB port for connection to a portable hard drive or thumb drive or printer or scanner or wireless adapter, etc. Click here for more details.

Problems with Email Attachments

Some of you may have experienced the problem of sending email with an attachment – a picture/image and later learning from the recipient that your picture/image cannot be viewed or view properly.

Cannot be viewed – main reason is that the image format is not supported by the recipient’s computer. Solution – advise the recipient to check on the image’s file extension (e.g. .raw, .pdf, .jpg, .ppt, .doc, .xls, .rtf, .gif, .png and the like) and obtain the appropriate image viewer or application programs. The most popular image extension is .jpg and is the default image format in all digital cameras.

Cannot view properly – the image is too large and only a small portion of the image is shown. Possible cause – image size (or pixel dimension) is too big. Most digital camera nowadays can take high and good quality pictures with pixel dimensions of 3072 x 2304 pixels or 2048 x 1536 pixels. Solution – get a photo-editing program and reduce image size to, say, 600 x 450 pixels before attaching the images to your email. 

Viruses, Spam, Pop-ups & Spyware

The web is filled with “free” offers. Some companies may allow you to test their versions of anti-spyware and anti-virus programs on the Internet. Be careful of bogus advertisement and “reviews” for products that actually install spyware and viruses on your computer. Take note that no reputable software vendor would ever advertise with a pop-up ad, an offer to scan your computer over the Internet and clear the viruses for you (for free) or an ad that looks like a Windows error dialog box saying “Your computer is unprotected.” Then request you to follow their instructions …

There are many reputable Brands of anti-virus and anti-spyware programs in the market. You can either subscribed on-line (if you know the URL web address of the reputable company) or go and purchase a copy of anti-virus and anti-spyware program and install onto the computer yourself.
