What is a Task Bar?

The Task bar is something you will use all the time, and believe or not in time it will become second nature. 


Today’s How-To Guide for the computer Beginner is What is the Task bar?  We will also go into the different parts of the task bar. 


You can see a small screenshot below, and if you can't see it clearly go to the picture directly on photobucket!


windows-taskbar

Most of the time you will find the taskbar at the bottom of your screen.


One the far left side of your taskbar you have your start button, start-button



and all the way to your right will be your computer clock. computer-clock

A taskbar is a visual device on the desktop that typically shows the user which applications (tasks) are currently active and running. Taskbars such as those in Windows operating systems also include icons for commonly-used utilities such as the system clock and antivirus software. In some systems, the user is allowed to modify the contents, location, or appearance of the taskbar. 




Different Parts of the Task Bar



Today I will go into a brief description of each part of the task bar, and in future lessons will go into more detail of the sections of the task bar.

start-menu

start-button


As we mentioned before the far left portion of the task bar is the start button that you hear people speak about.



When we click the start button we see a start menu.  We will speak about the start menu another day.

The second section of the taskbar has changed quite a bit in time.  I will write briefly about how this section generally evolved with each new Windows Operating System.

Next to the start button that opens the start menu you have the

Quick Launch Bar



The Quick Launch Bar was introduced with Windows 98, but was starting to be radically changed by Windows XP.quick-launch-bar



The Quick Launch bar was program icons that you use often.  One click and it would launch the program.  The red arrow points to the quick launch bar area.


The black arrow shows a double chervon (double arrow symbol), and when clicked shows additional icons that can be launched as well.quick-launch-bar 

You can see in this picture two bar looking items that separate the start button, quick launch, and then the middle section.

Some people like to change the programs that are in their quick launch bar, and we will speak about that another day.

Right next to the quick launch bar you have the middle section, which shows you which programs and documents you have open and allows you to quickly switch between them.


taskbar-open-iconsAs I mentioned before the task bar lets you know what ‘tasks’ are currently open.  In older operating systems you could have MANY tabs that looked similar, and it would fill the space up quickly.

windows-xp-taskbar-grouping


With Windows XP they started what they call task bar grouping.     They basically would ‘group’ all similar files together.  In the example I have pictured they grouped all Microsoft Word Documents together.

Keep in mind normally you would see your document name in this example if you gave the document a name that is.

They made this change so when you have like the picture shows 10 office documents open at once?  You can quickly get the one you need at the time, and switch to a different after that.  


vista-taskbar


When Vista came along all you had to do was hoover (See picture – windows photo gallery), and the Windows Desktop Manager would give you an image of the file or program you have open.


task-bar
  Instead of a bunch of grey buttons for each window that is open?  Vista (and XP) tend to show you a white down arrow that tells you that you have more than once window open.  In this case I have more than one webpage on my task bar.

taskbar

When I hover over the firefox icon in this case my web pages will appear like pictured.  If I hover again on top of the title?

The computer will give me a complete title of that the page in question.


Windows 7 changed it the taskbar once again.  When I hoover over (don’t click) that section the web pages with descriptions will pop up to tell me what they are as well.  


windows-7-jumplist
When you go to open a recently used program from the start menu the files you created recently show up as well.  If you look closely at the picture the ‘recent’ section (top right hand side)shows names of flowers that this person may have used in the PAINT program.  These files show up when you hoover over the program name.



windows-7-taskbar

These file names also pop up when you click the program icon in the task bar.  

Notice the “RECENT” file names this user created for meeting agendas.

If you look below that you will see the WordPad is the program they used to create them.  Windows 7 also makes it easier to place your programs of choice in the quick launch area.  

Notice the “Unpin this program from taskbar”.    

This user PINED WordPad to their taskbar for quick use.  If they change their mind later?  They can unpin it just by clicking where it prompts you to.


windows-7-icon

  Unlike Vista that gives me a white down arrow Windows 7 almost gives you the impression you have a couple of sheets of paper.  Notice the layers in the picture.

The notification area, which includes a clock and icons


notification-area-clock
  The area includes programs you tend to use once you turn the computer on.  It could be sound, virus protection, settings for printer, and important software.  Notice the WHITE arrow at the very left of this picture.  If you click on that you will see ALL the programs serviced by this portion of the task bar.  

This is for Vista.

windows-7-notifaction area

Windows 7 looks something like this.









The smaller icons as I mentioned are important sections of your computer
speaker
This is my speakers icon.  When I hoover over that icon I get a notification like this

speaker-notification

This is the same area in which you will be notified (with new operating systems) when an update to one of your programs is available.  Below is a Java Notification.

java-notification

Lastly, you have your clock that we have already covered in another lesson.


Thank you for reading our How-To Guide for the Computer Beginning, and our brief overview on the task bar.

As always don't forget to leave a comment or question if you have one in the area supplied below.

If you leave your email in the box I supplied future lessons will be sent to you by email!


How-To Uninstall Programs

From time to time you need to uninstall a program on your computer.  I know in the past my father seemed to think if he deleted the desktop icon the program would be GONE!

 

Unfortunately, there is a bit more to learning how-to uninstall a program on your computer.

 

I will also recommend a free program at the end if you are having problems ‘uninstalling a program’ the traditional ways!

 

Why would you uninstall programs

 

  • You installed a program, and your computer is freezing, or just not acting the same.  A times programs don’t work well with your operating system, and it doesn’t matter if the box says it SHOULD!

 

  • In a past lesson I discussed programs like Java.  Java is a free program that is very useful on computers, and at times like most programs they come out with ‘updates’.  So you agree to have your computer update to the newest version of java, and you find sites that you use java on now don’t work. 

 

  • Other times you get update program messages, and you agree to the update.  The next thing you know they program updating states you must ‘uninstall all previous versions’ before you can use the new one.

 

  • I have run into issues with a program that I regularly use, and all of a sudden for NO rational reason at all it completely flops.  It just doesn’t work anymore.

  • Other times you notice you never did use that program that you felt you would like, and why not just get it off the computer completely.

 

Yes there are different reasons to uninstall programs.  Learning How-to Uninstall a program is a very useful skill for the computer beginner. 


If you are planning on reinstalling the program make sure you have the location online for the download, or your program near by.


Below I will show you how to uninstall programs first on the older operating systems, and then we will move on to the newer ones.


With older operating systems you need to hit your start button, settings, and go to your control panel.

Start Button, Settings, Control Panel

Start Button, Settings, Control Panel

 

Look for your Add or Remove Programs icon.

 
Control Panel Add Remove ProgramsLook in Control Panel for Add Remove Programs Icon

 

Make sure you look to the TOP of the add/remove program properties, and see the section that is named 'Install/Uninstall'.  See picture below that shows the three tabs.  Click on the install/uninstall tab - the first one!

 

add/remove programs properties
Find the Install/Uninstall Tab Far Left
 
 

You will have a list of programs, and you need to find the one you are looking for.   You can scroll down the list on your right until you find the title of the program you wish to uninstall.  The program titles are in the white box below.



Uninstall Program you are looking for

Click on the program you wish to uninstall, and click the 'add/remove' button (see picture above – it is greyed out)  you see at the bottom of the listing.  Then push the okay button.

Click YES to uninstall program

Chances are you will get a message similar to the one I have pictured.  Its basically a 'are you SURE you want to remove this program?' type of message.  Click YES!

 

Then the program will uninstall, and you will see something similar to the picture below.

 

 

Keep in mind sometimes when you are DONE your computer will ask you to restart the system.  Its is completely normal!

 

The newer systems like XP, Vista, Seven have a different procedure for add or remove programs

What is nice about the newer programs is that normally have a ‘how-to uninstall’ option that you can use.

 

You would click your start button, then hit all programs. 

This will bring all your programs that are installled in order for you to find the program that you wish to UNinstall!

 

If you look at my picture above I choose CCleaner.  I clicked the folder first, and the list below it appeared.

 

You would click the Uninstall CCleaner, and just follow the easy directions.

 

What if you don’t have an uninstall option like I pictured above?  We can use the traditional how-to uninstall a program through the control panel.

 

In newer operating systems such as XP or Vista push start button and then control panel.

 

See Green Start Button – then hit control Panel

 

XP systems do have the 'add and remove' programs icon.

 

Vista in the 'classic' mode calls it 'Programs and Features'.  The classic mode has their icons in alphabetic order so it makes it easier.

 

If you aren't using the classic check out the arrow below under the programs section, uninstall a program.

Control Panel Uninstall a program












Uninstall a Program – See Arrow

 

Once your in the programs area - either way you get there classic or otherwise:

 

Wait for all the programs to refresh in the programs and features section.

Click the program that you want to remove

 

Look to the top of the white section and you will see some options:  Install, Remove, Repair

 

Click Remove to uninstall program

 

Programs and Features





Look for Install, Repair, Remove from top of control panel after you found program from list

If you are prompted to confirm the removal of the program, click Yes

 

Keep in mind at times you get the option of 'repairing' the program. 

 

If you having problems with the program? I would use reinstall it anyway.  If the repair doesn't work?  You are going to have to uninstall it anyway.  To me?  It just saves a step.

 

There will be times in which you will have a program that is HARD to remove, or just refuses to remove itself from your computer.

 

I know many people for example have issue with Symantec Norton products.  There is a software product that I have heard good things about, and its called

 

Revo Uninstaller

 

They have a free version, and a paid version.  I have used this product to actually REMOVE a Symantec Norton product from a friend’s computer.  It worked WELL!  Make sure you pay attention when you download it.  Its not a virus or anything, but sometimes vendors tend to wish to add extras like toolbars, etc along with the software.  You will see the option to say NO thank YOU!

 

I hope I helped you learn how-to uninstall a program.  Being a computer beginning some of these items I know can be intimidating.  Once you learn to THINK like a machine?  (giggles) it does get easier!

 

Have any questions or comments please see the comment section below!

Help! I have a computer virus NOW WHAT??

My father from time to time would be browsing the web, and some stinker website would tell him his computer was in trouble. He would quickly get OFF that site...freak out...and call me, "HELP! I have a virus NOW WHAT??" Yes there are sites out there that will nail you good with viruses after you clicked on something, but most often its from what you download from my experience. Those downloads are executed, and you really start having some issues! Today they are getting even more tricky! Most of the time Dad didn't have a virus, but on occasion he would get one. I still to these day don't know HOW! I would ask all the normal questions about what he was doing, and most of the time he plain couldn't remember! LOL!
anti virus computer virus One day he decided after he got another new computer, and the store had loaded up with anti virus program he did what he felt was a logical thing to do. He decided he was going to load TWO anti virus programs on his computer at once. He told me he wanted TWICE the protection! (Psssssssst! You aren't suppose to do that! It sounds good, but it can really mess up your system!) YES I did save his computer, and he didn't do that again! IT Does sound good, but save yourself and your computer from Dad's mistake - don't load more than one anti virus program on your computer!

There are some really nice free anti virus programs out there that you can try out, and later you can purchase if you are happy with them. I have spoke about some of them here!

Just to be safe! What is a computer virus? Newton BBS has a one page defination is that beginner friendly, and here is part of it! If you wish to read the entire defination click on Newton BBS to read it.
Computer viruses are programs written by "mean" people. These virus programs are placed into a commonly used program so that program will run the attached virus program as it boots, therefore, it is said that the virus "infects" the executable file or program. Executable files include Macintosh "system files" [such as system extensions, INITs and control panels] and application programs [such as word processing programs and spreadsheet programs.] Viruses work the same ways in Windows or DOS machines by infecting zip or exe files.

A virus is inactive until you execute an infected program or application OR start your computer from a disk that has infected system files. Once a virus is active, it loads into your computer's memory and may save itself to your hard drive or copies itself to applications or system files on disks you use.


WELL that is the bare basics of a defination, and recently I found a really neat website that might be helpful to others. This website is run by a computer company that works with virus and malware issues (among other things), and has some free tutorials online about how to rid yourself of them. I wanted to introduce you to this site instead of making personal recommendations since times change, and so do products! This is their business, and I would assume they will keep up on technology!

They made this site for people that already have a virus, and are trying to rid themselves of it. They want the hands on experience to do this themselves, and if they can't they have this company to help them with the rest!

If you don't have a computer virus it will introduce you to products that will keep your system up to date, and alot safer so that you DON'T get a virus! Its nice because they have a step by step tutorials, and videos along with it!

What are the different types of computers?

Imges of different types of computers - IBM
Image via Wikipedia
What are the different types of computers?
Goodness knows there are enough of them!

As you may have guess today’s How-To Guide for the Computer Beginner is to go over the different types of computers.

I will go over various types of computers today, and show you different photos of different types of computers so it will be easier to visualize.

I will go down a little personal history lane as well to remind you how far we have come with the different types of computers!

Desktop Computer or Desktop PC
Types of Computer - Desktop Computer
This is the type of desktop computer years ago, and you really thought you were doing great!

I remember those ugly screens, and those green letters on the monitor. 

If you look below the monitor you will see the floppy drive.   The 5 1/4 floppy disks were extremely fragile, and yet you needed to make sure you stored your important files on them.Photo of desktop computer

I have to wonder if these older computers are part of the reason I wear glasses today!  When I look at the newer desktop computers today?  WOW what a difference!

YIKES have we come a long way!

PC = Personal Computer

This last picture could also be part of a work station, but we will talk about that later.

These can also be referred to as a personal computer.

Computer Tower

Picture of Computer Tower
One of the different types of computers is something you may have already.  The computer tower I have pictured here is a bit older.  It still has the 3.5 floppy drive.  Today those drives are not even used anymore, nor do computer towers even COME with them most of the time!

The computer tower was a different type of computer than the past.  It was tall, and you could add more than one hard drive, floppy drive, CD Rom, etc.  It was the wave of the future!  If you wanted the CD rom on a computer?   You would have updated to one of these computer towers.  The early desktop computers didn’t have them from what I remember.

Today’s computer towers you don’t have your floppy drive, and at the time if you wanted to be cutting edge (with the old computer tower) you wanted different CD rom drives to lets say burn information, or make videos.   Its quite amazing now because the CD rom drives of today will even burn in image with lasers onto your DVD or CD roms instead of having the write the title on them now.

Your CD rom was great for storage of your files, and whepicture of type of computer towern you got your NEW computer tower?  You had a CD rom for each and every program in the past.  If you ran out of memory or hard drive space?  The towers of old – just as today – were meant to be able to expand.

Computer towers started to take over the traditional desktop you see above.   Although you do see the desktop computers they aren’t as popular as they once were.

The Technology advanced so much I’m sure we could put your entire blocks old computer tower information into ONE home personal computer today.

Laptop Computer
Types of computer the laptop

You also have your laptop computer. I have seen most young adults take these to college with them.

What I would have done to get my hands on THIS laptop compared to the green fonted monster pictured above from IBM.

Laptops are meant for portability, and they are not as powerful (most of the time) as desktop computers.  Everything has to be more compact.

PDA (Personal Digital Assistant)


 type of computer PDAMost people refer to this type of computer as a PDA.

PDA Stands for Personal Digital Assistant.

Generic term for handheld devices such as Palm Pilots that are commonly used to store address and calendar information. Newer models include networking features.


Years ago I had one, and it was nice…but the battery life was awful.
Palm Pilot various types of computers


I had my calendar, contacts, etc online, and I would ‘sync’ as they called it when I got home.  Basically you hooked up the device with a cable to your computer, and executed some software

The software would look for changes, and update both locations – the PDA and the online location.  It was nice when you placed notes in the device while you were away from the office.  You also had a copy of your most recently notes from the computer WITH YOU to make appts, notes, and update address information.

Today?  Everything is wireless, and I’m sure sync software is obsolete.  When I think of the history of the personal digital assistant?  Its really neat to think how powerful they are today.

handheld pc different type of computer
This different type of computer is also called handheld computer.

Personally, this would drive me up a tree! I don't want to type on something this small, and because my sight isn't the best. That screen would drive me nuts! There are people that love this type of computer, but its NOT for me!

It reminds me of the new and improved cell phones doesn’t it?  Our new and improved cell phones could be considered a PDA.

Tablet PC

This image with is different looking computer isn’t it?  This is the tablet PC.

With a Tablet PC you use an electronic stylus to write on the screen, just like with a pen and paper, only your words are in digital ink.
Picture of Tablet Computer
The Tablet PC saves your work just like you wrote it (as a picture), or you can let the Hand Recognition (HR) software turn your chicken-scratches into regular text.

Yes you can also put the button with your stylus like a keyboard as well.  Its neat to look at the progress that the tablet PC has made with time.


The Computer Workstation
Different picture of workstation computer They refer to this as a computer work station. The workstation to me is basically the whole complete package. Monitor, tower, keyboard, mouse, etc. Workstation is also connected to a network.


When talking about PC computers, most people probably think of the desktop type, which are designed to sit on your desk.

PC stands for Personal Computer. The tower and the smaller mini-tower style cases have become popular as people started needing more room for extra drives inside – as we talked about.

The Workstation is computers that are all connected together.

Computer networkA workstation that is part of a computer network and generally would be expected to have more than a regular desktop PC like memory, storage space, and speed.

If you see the picture networked means they are also connected together, and they share things like the printer or the scanner.



MainFrame Computer

What is a mainframe
This is called a mainframe computer. A main frame is the heart of a network of computers or terminals which allows hundreds of people to work at the same time on the same data.

It requires a special environment - cold and dry.

Example of Use:
Larger companies use this to hold on to information regarding your orders, contact information, etc. You may be talking to customer service but your information lands in one of these guys!   If you call one morning and speak to a representative in Illinois, and the next day call back and speak to California?  Chances are they are using the network hooked up together, and possibly on the same main frame.

In the early days of computing, mainframes were huge computers that could fill an entire room or even a whole floor! As the size of computers has diminished while the power has increased, the term mainframe has fallen out of use in favor of enterprise server. You'll still hear the term used, particularly in large companies to describe the huge machines processing millions of transactions every day.

SuperComputer

Supercomputer This is an example of a supercomputer. We are talking HUGE companies that use these. These are used for jobs that take massive amounts of calculating, like weather forecasting, engineering design and testing, serious decryption, economic forecasting, etc. Top 500 supercomputer site will show you these big daddies of the computer world!

Picture of Server part of computer workstation

The Server

When you talk about the various types of computer we shouldn’t leave out the server.

Have you ever called a company, and they told you they can't help you right now because their server went down? This is a picture of a server that might be used in smaller companies or home networks.

There are a couple of different types of servers, Computer Networkand here is a link to some computer definitions of server.

A computer that has been optimized to provide services to other work station computers over a network. Servers usually have powerful processors, lots of memory and large hard drives.   In this picture the brown tower would be the server.


Wearable Computers

Different type of computer wearable
NOW you can be ahead of some of your friends! THIS is called a wearable computer! Can you believe it?

According to Wikipedia®




Wearable computers are computers that are worn on the body. They have been applied to areas such as behavioral modeling, health monitoring systems, information technologies and media development. Wearable computers are especially useful for applications that require computational support while the user's hands, voice, eyes or attention are actively engaged with the physical environment.



One of the main features of a wearable computer is consistency. There is a constant interaction between the computer and user, ie. there is no need to turn the device on or off.

Another feature is the ability to multi-task. It is not necessary to stop what you are doing to use the device; it is augmented into all other actions. These devices can be incorporated by the user to act like a prosthetic. It can therefore be an extension of the user’s mind and/or body.  Amazing isn’t it?

Well! There you go with some of the different types of computers!   I’m sure with time we have to revised this article again.  The industry just keeps changing.

I hope you learned something today with out How-To Guide for the computer beginner lesson on ‘different types of computers’.
