Owing a computer is almost essential in today’s world. With the introduction of the internet and the convenience of email as a method of communication, it’s easy to see why most people want to have a computer in their home or office.

Computers are like anything else and there are times when they don’t operate as planned. It’s frustrating to be sitting at your desk ready to play a game or work on a document only to find that your computer isn’t being cooperative.

When it comes to computer repair it’s often wise to seek out professional help. A computer technician is specially trained to evaluate the problem and offer the best possible solution.

There are certain types of computer repair that you might want to undertake yourself. These are usually minor fixes that can be handled with a bit of instruction and attention to detail.

A computer repair that you might be able to take care of yourself is the replacement of the computer’s battery or fan. Every desktop computer has a fan inside of it. This fan is used to keep the computer’s components cool. It’s essential that the fan operates efficiently to ensure that the computer doesn’t become overheated.

The first sign that your computer’s fan might not be operating properly is that you’ll notice a different sound when you start or run your computer. Instead of immediately taking it to a computer repair shop, take a moment to test the fan.

Computers typically have two fans. One is used to cool the power supply and the other is used to cool the CPU. Open the cover of the computer and listen. If the sound does appear to be coming from the fan that cools the CPU you’ll want to replace it.

If the computer is still under warranty than this type of computer repair will be done free of charge. Follow the instructions you were given for repairs at the time of purchase. If the warranty period has elapsed you can either take it to a computer repair shop or do it yourself.

The very first and most important step when doing any computer repair is to unplug the computer from the electrical outlet. You’ll then need to examine the fan to see how it’s connected. It will probably be attached by a few small screws. Once these are loosened you’ll need to disconnect the fan from its power supply. This will be one or two small clips. Then take the fan to your computer repair shop and purchase a new one.

After replacing it, reattach the cover and plug the machine in. The fan should operate perfectly now and the noise that you were hearing will have disappeared.

Sometimes a computer will make noises because a piece of hardware isn’t attached properly. One of the likely culprits is the CD-Rom or DVD drive. Again for this type of computer repair, you’ll want to carefully remove the cover and listen for the source of the noise. After tightening the screws that hold the hardware in place and reattaching the cover, plug the machine in and listen if the offending noise is gone.

When it comes to computer repair it’s important to be safe and thorough. Computers are an expensive investment and keeping them running efficiently is crucial. If you are comfortable handling a small computer repair yourself, give it a try. If you’re not comfortable, take the machine to a local computer repair shop and allow the experts to do their job.

Router is a computer device that receives or forwards data packets to and from the Internet towards a destination in the process called routing. Router is the essential component of the computer networking that enables any sent data to arrive at the right destination.

As an illustration, imagine that the Internet is the world and one computer is one household. Other computers connected through the Internet are households around the world. Say one household will send a letter to another household in any part of the world. The letter has an address right? And that address would determine the destination of the letter. But without one reading the address, the letter would not arrive to the right receiver. The letter also would not be able to reach the intended receiver if there is not medium. This medium would be the courier. And the courier of the computer data is the router.

A router (broadband router) is also a device that enables two or more computer to receive data packets from the Internet under one IP address at the same time.

Remember that to be able to connect to the Internet, a computer must have an IP address unique from the rest of the computers. Therefore, every computer connected to the Internet has it own IP address. It is like having a fingerprint or ID as an access pass to be able to enter the web. With the presence of the router, this “fingerprint” or “ID” could be shared by two or more computer at the same time.

In simplest form, a router makes two or more computer use the Internet at the same with one access pass.

One more thing: a computer with cable modem could also be considered as a router. In this, the computer would do the process of routing like normal routers do. Other computers are then connected to the computer with Internet connection that would give it with the Internet connection. The computer with cable modem has the direct contact with the Internet and the ones connected to it are sharing the connection.

Why would anyone need a router?

For households with two or more computers who would want to have Internet connection to every computers they have, taking subscription for each would be too much. The solution is to buy a router that would enable every computer in the house to have an Internet connection. In the definition above, the broadband router would act as a hub to the existing Internet connection.

If the router is comparable to a hub, would it affect the Internet speed?

It should be taken into consideration that once a single Internet connection is divided, the connection speed is affected. But there are some broadband routers that would bring minimal slowdown to the Internet speed and the effect might not even be big.

Internet speed would also depend on the type of application used in a router. While some would inflict little effect on the speed like online games, others would terribly slowdown your connection and even hinder you to use the Internet at all.

Usually, offices use a more sophisticated router to redirect Internet connections to the large number of computers. These routers would give better data packeting compared to a typical router used at home that results to faster Internet speed.

Like a brush is to a painter an essential skill in the field of graphic design is Photoshop. The software offers increased productivity as well as flexibility. The features include aspects like file browser, vanishing point tool, smart sharpen filter, noise reduction filter, smart objects, as well as camera workflow enhancements. Photoshop offers professional photo editing features, digital imaging, as well as non destructive editing.

There are so many hidden features and insights to software, that it is often impossible to know them all.

1.    There is a hidden option using which you can simulate bold and italic formatting styles for fonts that do not have these options. Click the button on the type tool option to bring up the character palette. Then select text and click the arrow in the upper right hand corner of the palette menu where faux bold and italics are present. However you will not be able to warp type when formatting has been applied.

2.    One can quickly flip through blend modes while trying out effects by using the keys “shift+ to change to next mode and shift- to go to the previous mode.” When a painting tool is active this shortcut will change the blend mode of the painting tool. However, if anything is highlighted then the shortcut will not work. You will have press esc and then use the shortcut keys again.

3.    The photomerge feature can be used to seamlessly combine multiple images to create a panorama. This feature can be accessed from the Automate menu. You can even refine the composition using tools like rotate, zoom, pan, and set vanishing point.

4.    When re-sampling images one can use either Bicubic Smoother or Bicubic Sharper. You can use Bicubic smoother for up sampling and Bicubic sharper for down sampling. You can actually specify which interpolation method is to be used by going to general preferences and setting a default.

5.     There are two features for printing. You can use contact sheet II or picture package. Use contact sheet when you want all images in the same size and you want to print the name below the image. Use printer package when you want different image sizes on the same page, or multiple copies of the same image, or a text overlay.

6.     If you want to remove a glare on the eyeglasses of an image you should use a part of the lens that does not have a glare and use it to layer the lens with a glare. Use tools like rotate and skew and soft-tip eraser to soften the edges. Ensure the glare does not show through from below. Or, do some careful work using the clone tool.

7.    The online services enable you to connect to online photo printing and sharing sites.

8.    The Web Photo gallery can generate hyperlink pages that can be uploaded to a server.
9.    The Picture Package option will help you prepare photos in layout with multiple size prints on one page.

10.    You will never forget how you achieved a certain result because the History Log will detail every step taken by you as well as time-tracking, and a legal record. There are three choices wherein, you can create a sessions only record where, it will record only when Photoshop is opened or closed; or a concise record which will record each action including the text that appears in the history palette; or the complete editing history including the text that appears in the actions palette.

Adobe Photoshop is a dream tool for every designer and one can over time master every subtlety of the tool and crop, rotate, resize, create shapes, add layers, change text, and play with colors.  It is a hands on software where the more you use it the more you will learn.
