Independent Operating Systems Explained

An Operating System is described as software made up of data and programs that is a common feature on most computers and completes a variety of functions such as managing computer hardware resources as well as providing common services to assist with the execution of the operations of various application software (computer software which is designed for the express purpose of helping the user to perform single or multiple related tasks, such as media players, office suites and accounting software). For hardware functions (such as memory allocation and input and output), the operating system acts as a kind of ‘middle man’ between the computer programs and the application software.

Operating structures can be considered quite probably the most important examples of system software that is present in a computer system since without an operating system, it would be impossible for a user to run an application program on their computer (that is of course unless the application is ‘self-booting’ and therefore would not require the assistance of an operating system). It is for this reason that operating systems are found on almost every device that contains any form of computer, ranging from top of the range supercomputers and web servers everyday technological devices, such as video game consoles and even mobile phones.

Components of operating structures include the Kernel (the most important of all components of an operating application) which acts as a bridge between application software and the actual data processing that is conducted at hardware level. Responsibilities of this component include managing the resources of the system (the managing of the communication between the hardware and the software components). Interrupts (asynchronous signals which indicate the need for attention or indicating a synchronous event in a piece of software that needs a change in execution) are another essential part of operating applications, as is multitasking (the running of multiple independent computer programs on the same computer).

It is often the case that application software is written to be used on only one single operating system (and sometime even for one specific piece of hardware) and as a result it has become possible in recent years for computers to support a number of different independent operating structures. The cost in supporting a number of diverse operating applications can be avoided by the user instead writing applications against software platforms (a crucial element in the development of software) such as Java.

Windows Operating System Software – Why is it So Slow?

It is not just the windows operating system software that is slow other operating systems are also slow compared to when they were first developed. The vast majority of people especially those who have not been involved in the technical area of computers grew up with the likes of the windows operating system software or Mac operating system. They have not known the time when computers seemed to be lightning fast yet were only a fraction of the power of today’s PC’s.

Let me give you a bit of history. Computers in the past were programmed in what were called low level computer languages, assembler and even machine language that made the programs much more efficient. But as the years went by calls for more functionality and languages that were easier to write programs.

Then came the higher-level language compilers like Cobol, Fortran and a sudden splurge in a many others. Although these were still reasonable efficient, the fight began for compiler companies to produce more efficient ones to combat the need for that increasingly extra functionality being asked for that were slowing the computers down.

The efficiency of compilers was measured in how much machine code was produced to perform a certain task. If one compiler only 10 machine code instructions to perform a single task and another 20 you can guess which one was the more efficient. This was not always the case because it was also dependent upon the actual machine instruction used. The hardware was more efficient performing some than others.

Getting back to why the “windows operating system software” The first release of “Windows” seemed to be pretty fast and was so (compared today’s PC’s) working on pretty low powered computers. As Windows matured and users upgraded to new versions of the windows operating system software they found that their PC’s were running slower and slower. They also found that they needed to use more and more space on their hard disks for the new operating systems.

The slowness of the windows operating system software was partially offset by buying a more powerful PC and a bigger hard disk. Buying more disk space and memory became mandatory in some cases because the new operating system could not even be installed on the old PC. There even came a time when programs users had bought would no longer run under the newer versions of windows. Talk about double whammies. It would almost appear that OS suppliers and hardware suppliers where in cahoots with each other to keep the money rolling in.

This is not totally the case as users were asking for all this extra functionality quite unaware that it was going to come at a cost. At the same time there is another double whammy. Because of high-powered computers the “developers” of software used, efficiency of the produced software was thrown out of the window. (Pun) Developers didn’t give efficiency a very high priority, (Just buy a more powerful computer). They want to get the product out the door and start earning.

Some operating systems are more efficient than others the most efficient being “Unix” the next is “Linux” probably followed by Mac and last being the windows operating system software.

You may find that if you have “hosting” and check what your host provider is running your hosting account on, you will invariably find that it is running the “Unix” or “Linux” operating system. You will find some that are using the windows operating system software. Personally if I find this is the case I will not go anywhere near that hosting company.

Unfortunately higher-powered PC’s also make us slack. You start off with your windows operating systems software running at a fairly fast pace but as time goes on it runs slower and slower. This is the case with any operating system no matter how efficient it is. The windows operating system software is like your car it needs maintaining periodically. If you did not maintain your car it’s performance would gradually decrease and the number of breakdowns would occur more and more often. That is why you need to do some maintenance your self and have some done by specialists. With a car you check the oil, tyre pressures and other small tasks but you send your car off to the service center for the more difficult things.

Which Microsoft Operating System Do You Need?

It is very easy to choose the operating system that everyone else is running. It is true that today’s most commonly installed operating system is Microsoft Windows. It is also true that it does what most people require.

The problem is your needs may be very different from the average person.

For this very reason you need to ask yourself a few questions before deciding on an operating system for your PC. It can be a difficult task to change down the line.

Microsoft has a done a sterling job on its operating system. They’ve made everyday computer tasks very easy to accomplish. It is a user friendly operating system for sure.

The only problem with Microsoft’s current operating systems is that they are not coded very well. Their operating systems are resource hungry. You need to make sure you have enough system memory to run multiple programs. Windows is great looking but also requires a capable video card to run smoothly.

If you are looking for speed then you may want to consider older operating systems from Microsoft. Windows XP is still very widely used and is arguably the fastest of their operating systems. Most of today’s software is also compatible with XP as it has a large install base.

The reason XP is faster is because it’s not fancy. The graphics in windows XP are simple. Vista and Windows 7 have a lot of graphical transitions that really bog down a PC.

Is the operating system suitable to your Hardware. Your shiny new components may not work in Windows XP. Do some research on the hardware your computer has and whether drivers are available for XP. All modern components will work in Windows 7 and Vista. Vista and Windows 7 look great. Just remember that if you’re going down this route you will need a good 3D capable card which drives the cost of your PC right up. If you’re not going to be playing 3D ready games or doing intensive video or graphic designing then you don’t need a 3D card. So windows XP would be a good choice.

Which brings us on to gaming. If you’re going to be running the latest games you will be dependent on the latest versions of Direct X. Support is far better in Vista and Windows 7 than XP. Lately, games have been released that will refuse to run on XP.

Windows 7 and Vista both have built in software to protect you against malware and spyware. You will need to find your own anti-virus solution though. Windows XP offers no protection except a basic firewall. So you will have to fork out some of your hard earned cash for the extra programs.

Before going ahead with your PC please make sure you have looked at the following points to prepare you.

Backup all of your documents that you cant afford to lose. It may be a good idea to invest in an external USB hard drive that you can copy all your documents that just cant be replaced. You can also use an online backup service to backup your documents. This is not the best option if you don’t have a high speed internet service. Another option is backing up to DVD.

Read all the instructions for installation. Windows Vista is very easy to install but it is a good idea to be prepared before making a mistake that cant be reverted. There isn’t much to know, but be prepared.

Go through all your components in your PC and check with the manufacturers website to make sure it is compatible with the operating system you intend to install, then download all these drivers to disk. A common mistake made by many is not downloading the network drivers. Its difficult to get online to download when your network card is not working.

Seek guidance from a friend. If you have a friend that has installed the same operating system ask him about any pitfalls.

Something which is often overlooked when a problem occurs is the operating systems support line. If you run into any problems give them a call. Microsoft’s staff are often very helpful and knowledgeable.
