Graphical User Interface Basic Knowledge – Part 2

Wednesday 25 November 2009 @ 1:10 pm

Hello… nice to have you back on this site, I will continue the discussion in Part 1.
Ok then, lets start….

Minimize, Restore and Exit buttons.
These buttons will allow you to minimize an application’s screen, restore the application to the original size or shutting down the application.
These buttons usually located on the top right corner of a program.

Scroll bar.
This button is used to move up and down or change between pages. Usually this button is placed in the right side of an application.

Status bar.
It is used to display a small message and to show the progress of a task or command. In most programs, it is located at the bottom of the user interface.

Context menu.
When perform a right click on your mouse, a menu will be displayed. That is a context menu.

A context menu is commonly used as a shortcut command.

Input box.
Input box is a small rectangle, usually use to input a set of data in a program interface. As an example when you open up your web based email, then you must enter your username and password into a rectangle box, that is an input box.

If you have a problem regarding this input box, then you might present the exact type of information to the technical support by calling it an input box so the problem can be directly solved.

Button.
A rectangle box that can be click, and when you click on this rectangle box, it perform a process. As an example when you to print your document, after pressing the Print menu and then followed by the OK button, your document start to be printed.

When the color of the text in the button is gray out as it seems like inactive and nothing happens if you click on it, then a problem occurs.

Check box.
A small box that indicates multiple choices, such when you are completing a registration form then you were asked to select your hobby, several choices will be provided in that form.

By the time you click on it, a small ‘x’ will be displayed inside the box.
Radio button.

Almost the same as a check box, but radio button indicates a single choice.
Problems with check box and radio button are almost the same, which is if you click on that button there is no reactions.

If you try to describe the problems with your software to a technical support, make sure you mention the parts correctly to get a proper problem solving.




Graphical User Interface Basic Knowledge – Part 1

When you are having problems with your computer software, sometimes you will need the help of a technician, the first rescue will be done by phone or live chat, or whatever media that doesn’t require the technician to come into your place. The technician will guide you step by step to resolve the problem.

In order to get the right analysis, the technician will need to know what is the problem.
In this first step, it will be your part to explain the technician what the problem persist.
To get the proper help, then you must describe the problem in details. The main problem is when you can’t describe the problem in details just because you don’t knowing how to do it.

If it happens, you can’t expect your problems solved by the technical support.

Through this article, I will describe the correct names for the most common components of software. I hope later on, you can understand and describe briefly to a technical support when you are having problems with your software. By describing in details you can expect good analysis and problem solving from technical support.

User Interface.
It contains squares, boxes, buttons, words and icons. This is the visual design of a program.

As an example you may see a warning message that pops up in a square box in the user interface of your software, when you are experiencing insufficient memory.

Title bar.
Most programs will use this part to display its name or describe in what section of the program you are currently.

You may see a wrong description if the program is incorrectly coded. But, this rarely happens.

Menu bar.
In this part, user can see the menu items and options.

Most common programs will have File commands, Open commands, Save commands and Print commands in this section

An error example in this section is if a menu that must work but can’t be click or its color is light gray.

Tool bar.
This part can be recognized because it contains icons. Usually it is placed on the top of the interface.

When you are clicking the icon, it will execute a certain command.

The problems persist in this section is uncommon. If you click on the icon but nothing happens, then you can describe the problem by referring the icon’s name or the toolbar’s name.

Well, I hope you are not getting bored with this long explanation.
Please allow me to take a break for this part.
Check back to this site to read for Part 2 …




Computer Accessories

Wednesday 11 November 2009 @ 7:56 am

Computer that we buy usually is just a Starter Kit.
It includes a set of CPU unit, monitor keyboard, mouse, and a set of speaker (optional).

For some people that is probably just doesn’t matter. But, for other people that is not enough specially with the latest technology update. They need more than standard package.

Recently, computer with a full multimedia capabilities, good graphic tools, and able to accommodate various portable are needed by users.
The only way to get those extras is by accessorizing, because the extras are not included in a standard package computer.

I’m going to use a pizza as an analogy.
A brand new computer is a plain pizza, we need to flavor and bake it to turn it into something useful
To make this plain pizza turn into a delicious pizza, we need to “accessorize” this pizza with an onion, cheese, chicken, beef, and everything else depends on your favorite.

Just like a plain pizza, this new package of computer is standard (plain). It requires to be accessorized.
Accessorizing a standard computer doesn’t have to be so expensive, but it depends on what you need to use the computer for. If you need the computer for children, you can spend less expensive for an extra software and hardware.

If you use the new computer that you buy for working purpose, that requires a high quality result, than it would be more expensive.
And if you need more peripherals such as microphones, video cameras, digital cameras, scanners, PDA’s and more, that is going to be a lot more expensive.

Accessorizing computer sometimes can become another important thing to consider besides cost. The best time to buy is when you buy a brand new package of computer.

You probably wonder why can that be another important thing to consider.
Because technologies are growing rapidly, manufacturers develop new technology continuously. If you decide to buy accessories later, by that time a newer technology have been released and probably you computer can’t accommodate the new peripherals.

That kind of problems are usually experienced by users who are attempting to use hardware that were designed for Windows Vista on Windows XP or Windows 2000 machine.




How Computer Viruses Spread

Wednesday 4 November 2009 @ 12:15 pm

Virus is a computer program that able to spread from one computer to another computer.
They are designed specifically to gain access into parts of your computer system and they have the ability to duplicate and infecting another computer.

Below is some of the most common methods for a computer virus to spread.

Boot Information

Every disk (hard disk, floppy disk, CD, DVD) contains a boot sector even if it is a bootable disk or not.
When you turn on your computer, then it will search for boot information.
If the computer finds a disk containing boot information, it reads the boot information and uses it to start the computer in normal procedure.
For an example if you accidentally boot your computer from a bootable CD that contains a computer virus, that way the computer virus are being triggered and it is possible to be transferred into the computer’s hard drive.

After the boot information on the hard drive has been infected with the virus, it will be loaded into your computer’s memory every time you start your computer. From that memory (RAM) the computer virus infecting every disk that attached with your computer. This is how the infection spreads.

Most boot viruses could stay on a computer system for a long time without generating problems, it was designed only to stay there and spread themselves.
Such computer viruses are designed to activate their bad behaviour on a specific date depends on the creator.
But there are some nasty boot viruses that can destroy the boot information or forcing a complete format of a hard drive right after they are transferred into a computer.

Application Infections

When a computer program that has been infected with a virus is running, the virus is loaded into the RAM.
While the virus is in the RAM, if you are running another application that application can become infected.
It means that more applications on your system are possible to be infected.
Multiple infections are very common and it will definitely generate system problems.

For some time the program files may operates normally without any problems but eventually they will have problems or the infections causes the whole computer system down.

Generally, when an application is infected with a virus, the first sign of an infection is when you are saving files it is saved without a proper names or the data that you save is incomplete.
This type of viruses are often designed to search for a programs that are used to share information between users/computers such as email applications, screen savers, office document Macros, and self-extracting compressed files.

E-Mail Attachments

Most of dangerous viruses are spreading through an e-mail attachments.
In such cases, the user does not realize that they are attaching infected file/s to an email message and send it to a friend/s or colleague/s.
By the time that email is received, the virus is triggered when the attachment file is opened then infecting a new computer.

These days mass mailing email contains worms or viruses are being released.
These kind of attacks AUTOMATICALLY scans your computer’s files and search for any email address it can find and uses your email application to AUTOMATICALLY send infected messages to every email address that it has found in your computer.

It is very important to be aware over the emails that you open. Make sure that it does not contain dangerous viruses.
Even if that email comes from your family or friends, it may contain a virus.
This is the moment where an anti-virus program would be really helpful to detect your incoming messages and to make sure that the messages you receive does not contain a virus.
