A fish doesn’t notice that it’s surrounded by water. Water is just a normal part of its environment that is taken for granted.

In the same vein, for a very long time, IT managers have viewed as fact that enterprise WAN bandwidth is very scarce. Despite all the advances in technology, from 100Mbps Ethernet links to every desktop and Gigabit Ethernet desktop connections, network managers live with the reality that a 1.5 Mbps T1 WAN connection shared between anywhere from 5 to 50 people is often times all that is available.

The substantial lack of availability of bandwidth on most WANs has a striking impact on the design of the corporate WAN, and on what types of applications can be effectively run on it. Compounding the problem is the economic reality of our times, and the fact that spending twice the budget to achieve the same bandwidth is just simply not an option for most companies.

However, there is a new technology available that can achieve 20 to 30 times the existing WAN bandwidth that has been previously enjoyed. The technology is Adaptive Private Networking (APN). While almost all techniques from WAN Optimization vendors like Riverbed and Blue Coat are about conserving bandwidth, APN actually takes the opposite approach, focusing, much as RAID did with “cheap” PC hard disks for storage, on making inexpensive bits business quality.

Rather than discussing how APN works here, I’d rather focus on the possibilities that are now available on an enterprise WAN that were previously unthinkable due to the lack of bandwidth. Videoconferencing is a great example. Because APN uses a high volume of inexpensive Internet bandwidth, it makes it affordable and achievable to run high definition videoconferencing to even your smallest branch offices on a “converged network”. Start thinking about the applications you could run, and the centralization redesigns which would be possible, if only you could increase bandwidth by 20 times on your WAN.

Over time, even the most sophisticated, memory packed computer can begin to run slow if we don’t do something to prevent it. The reason why has less to do with how computers are made and how they age and more to do with the way we use them. You see, all of the daily tasks that we do on our PC from running programs to downloading and deleting software can make our computer sluggish.

To keep this from happening, you need to understand the reasons why your PC is getting slower and do something to keep your PC running at its best. You can do this through regular maintenance and PC performance optimization programs.

Before we discuss all of the things that could be affecting your PC’s performance, let’s talk a little about what symptoms a slow computer can have.

In addition to being excruciatingly slow when it comes to opening programs or finishing tasks, your PC may also experience data loss, unwanted shutdowns, Windows crashing and Windows hang up. All of these can be very annoying to deal with and are a sure sign that you need to optimize your PC and maintain it.

There are many reasons why your PC is getting slower and not performing quite the way it used to. Any one of them may be just the thing that is holding your PC back. In some cases, there is more than one culprit at work. But there are solutions to keep your computer from being affected by these nuisances, and we will talk about what you can do to maintain your PC and keep it running smoothly if it encounters any of these problems.

When you download and use programs on your PC, sometimes they are set up to start running as soon as you turn on your computer. These programs may be running in the background without you even knowing it and they use up precious memory needed for other tasks.

To see if you have any programs running in the background, press Ctrl + Alt + Delete at the same time.

A list of all of the currently running programs will appear in a pop up window. You can choose to stop the programs by highlighting the program and clicking “end task.” If you want to keep those programs from starting when you turn on your PC, change the individual settings for each program so that they will not automatically be turned on.

Memory is a computer component that allows it to do all of the various tasks that you require of it. When you start to do a task, a segment of memory is assigned to that task. If you don’t have enough memory and you try to do several tasks at once, you may run out of memory and not be able to perform any tasks properly. In order to optimize and maintain memory, you can use a Memory Optimizer program. This program changes the way that Windows manages memory so that you can use it more efficiently.

Your hard drive is like a huge filing cabinet containing all of the files that you need for your computer to perform properly. When you add programs, files are added to this data base. When you delete data or programs, files are removed. This process results in holes or empty spaces in your filing cabinet.

These holes make it harder for your computer to work because it continuously has to search for information over a larger distance and sometimes search for information that is completely out of order. To combat this, you need to defragment your hard drive. You can do this with your Windows system optimization tools or with a Registry Deffrager and Optimizer. These programs eliminate holes and arrange your files in a sensible order.

Just as your PC’s hard drive could be filed improperly, it can also be too full to work at its best. A good rule of thumb is to have at least 2MB to 3MB of space on your hard drive for your PC to function properly. To free up space, simply delete unused programs on the C: drive.

Maintaining your PC’s performance is vital if you want you computer to always complete tasks at its top speed. While Windows has some system tools to help you do this, they do not work on their own. You have to actually go and start the programs to optimize your computer. And they may not be enough. In this case, you may want to opt for optimization software such as PC Programs to help maintain your PC’s performance.

It is a good idea to think of your PC as an office. It stores files, programs, pictures. This can be compared to an actual office's files, machines and decorations. The operating system is the boss. With this image in mind, think of an office you've visited that was slow and inefficient. There were probably many different reasons for the inefficiency. This is the same with a computer. There can be many items that slow down your computer. Perhaps the one most commonly overlooked is disorganization and clutter.

Disk Cleanup

An office can accumulate a lot of unnecessary files, machines, and decorations. This is the same with your computer. One of the best ways to keep this clutter under control is to perform a cleaning utility periodically. In Windows this cleaning utility will be called a "disk cleanup." It removes a variety of unnecessary files depending on the options you have selected.

To perform a disk cleanup on Windows XP you can simply click on "my computer" under the start menu. Than right click on your "c drive" or "hard disk" and choose properties. Than click "disk cleanup" and follow the prompts. When selecting files to clean up, or delete, Windows will give you information to help you decide. When looking over the list of file types, you would simple click on the name of the file type and read the description placed below in the description area. This will let you know if the files can be safely deleted. To select the file group just check the box next to the group name. When finished selecting press "OK" to finish.

Now, performing a disk cleanup is not very time consuming, just a couple minutes, and it may save more time in the end by making your computer run faster. However, a disk cleanup should be run periodically rather than just once in a great while. One way to make this run periodically is to make it a scheduled task. This will allow your computer to run it automatically with intervals and time of day determined by you. Yet, you can always run it yourself periodically without creating a scheduled task.

Add or Remove Programs

The information given above can help you get rid of some unnecessary files, but you may also need to clean out some unnecessary programs as well. This can be done using the "add or remove programs" utility in Windows. This is located in the control panel and lists all of your currently installed programs along with an option to uninstall them. It is a good idea to browse through the add or remove programs utility every once in a while just to make sure that all programs are of usefulness.

If there are programs listed that are no longer used, you can simply highlight the program and click the uninstall button. Windows will than begin the process to uninstall the program. In most cases, to finish uninstalling a program, it is wise to restart your computer. This will dump and files that are held temporarily.

The add or remove programs utility is very useful, but not all of the programs are listed up front. Programs that come pre-installed on your computer and the Windows operating system can also be uninstalled. For instance, Outlook Express is a default e-mail program that comes with the Windows XP operating system. If you do not use this e-mail program you can uninstall it. Click "add or remove windows components" found in the add or remove programs utility and simply follow the instructions.

Defragment

Many offices contain a large number of files and programs that are valuable and cannot be thrown away. In fact, they may contain files that are not even used, but still have to be retained for some reason. Although these files must remain in the office, they need to be organized. This is why we create file folders that hold groups of files that are related. Than we store them in cabinets that are arranged in alphabetic order.

In a computer, the files that are saved are placed on the hard drive. However, they are placed according to the time that they were saved. So, if you open a word document and save the file as "file A" and than open another document and save it as "file B", you have a "file A" placed next to "file B." This is fine, but if you open "file A" later on and save it again, than the added information is saved next to "file B."

When files are broken up this way it is referred to as a fragmented file. This means that the computer must find the first part of the file and then find the second part of the file to open that one word document. This can make your computer run slower. However, Windows has created a utility that is meant to rearrange files so that they are no longer fragmented but sit right next to each other.

You can run the disk defragmenter by selecting "all programs" under the start button. Next, select "accessories" and "system tools" and you will see "disk defragmenter." In fact, this is also an alternative way to select the disk cleanup mentioned earlier. Before starting the defragmenter you can analyze your hard drive to see if Windows recommends performing the defragmenter. It will either say that you should or should not defragment at this time.

If you need to defragment your computer, simply hit the defragment button. It may take your computer a while to finish this task depending on the speed of your computer and the amount of defragmented files. It could take from about 15-30 minutes or more. However, you can still use the computer while the disk defragmenter is working.

Technology, on the one hand, improve and support human life, while at the other side destroy. Technology is always with the consequences, the technology is not neutral, said Naisbit (1999). Information technology (IT) is the product of creative imagery and the human dream, its has become an integral part of the evolution of human culture. Efficiently utilize IT, but with results that are optimal imperatives, to replace the line resultan consequences that (tended) are on the positive side. Necessary changes and behavioral paradigm that IT benefits exceed the costs that have been issued for the investment and energy. Benefits, not only gives computing solutions, but also give a positive contribution (read: keep) the universe in the form of reducing deforestation or forest degradation. IT is a product of Hitech have connotations with the city and is associated with modern thin forests more closely with "tarzan" and primitive. Is there a connection? Green computing is the answer. Although we rarely (or never) heard, this is not a new term in IT. Clear, green computing is not computing or primitive computing, but modern computing solutions and civilized. It is the nature of a self-organization or individual, if only utilize IT to provide computing solutions only, and receive data as the information that has meaning for stakeholders. But if the only stakeholders with information, in the concept of green computing called Shareholders. Green computing concepts to consider the triple bottom line (3BL)-human, planet, and profit-as stakeholders (en.wikiedia.org). Green computing is the behavior of using computing resources efficiently, how to maximize energy efficiency, extend the life of the hardware, minimizing the use of paper, and some other technical matters. Referring to the concept 3BL, IT development-based system must consider all the elements of the stakeholders, not only to maximize profit Shareholders only. Green computing has been able to prevent deforestation? Yes, this is visible from a study conducted by Javelin Strategy & Research (Shapley, 2007) indicates that changes to Internet Banking on 53 percent of Bank of America, logging has been able to save 16.5 million trees each year. How the application of IT in UNY? From the academic side of the transaction, which is the only one of a number of IT-based system available, able to reduce the use of paper up to 85.71 percent. This figure is derived from the reduction of paper transactions to card a study plan (KRS) to 67 percent and the results of a study card to almost 100 percent. When converted to the needs of timber, the current UNY only require 2.2 trees per year compared saaat not apply IT in full (Hybrid), which requires a tree 15.43 per year, meaning that 13.23 save trees each year. Two examples are only the view from the side of saving paper only, which is one of several components of green computing. In principle, green computing related to a series of three entities, namely hardware, software, and users (individuals and organizations). First, from the hardware side. Can be IT hardware (computers, a media store data, and monitor), which produced around the mid-1990s have been eligible green computing. Hardware has features, power management, we can see on the Energy Star certification progran on the hardware. Energy Star was launched in 1992 by the Environmental Protection Agency (EPA) the United States, and revised in October 2006 with further improve the efficiency of the device on the computer. Second, from the software. Standard industry Anvanved Configuration and Power Interface (ACPI) set strandar programming interface that allows operating system (OS) directly control the power consumption savings of the hardware. The savings occur when the OS automatically turn off the monitor and peripherals such as hard disk of the computer after not active during a certain period, or hibernate in the process of a laptop computer. All this will occur if the user to activate the feature. Third, from the users, namely: individuals and organizations. Factor is the fact that the main problem in realizing green computing, because it awareness of individuals and policy organization, which in turn will form a cultural organization. From the individual, each person should have the awareness to enable the features, power options, which are provided on each computer that the device is in the responsibility. From the side of the organization, to start to implement the policy less paper for all administrative systems have been utilizing IT has a big impact. Parsimony these figures will be far greater savings when calculating the entire IT system based on the available such as online payment system in Indonesia in Bank UNY partners, e-lettering system, electronic journals, video library, e-learning, and optimization of the e-mail as communication facilities. IT UNY supported by Giga bits intranet-based fiber optics, Internet bandwidth to 10 Mbps, 20 antenna Hotspot in all areas of campus, and virtual private network (VPN) to the campus outside Karangmalang, has made "shoo" UNY become so integrated in the campus. This facility is still supported by a disaster recovery capabilities to ensure data security. Is a form of refuse and reject the concept of digital 3BL, when insfrastruktur IT already available (which has been strictly electric power) is not used optimally. Application of IT is not a factor in the penjumlah old paradigm, because the only result will be the paradigm of the old expensive, redundant, and not environmentally friendly. But more than that, IT is seen as a trigger Enabler and changes evolutif old paradigm towards a new paradigm. These changes occurred in individuals and organizations that will establish a modern organizational culture.
