If you are familiar with the computer then you must know that it runs with the help of various softwares. Not what exactly is software? Well the easiest answer to that would be it is a set or a group of instructions which takes the help of the system hardware and in return gives the output which the user wants from it. Now softwares are divided into 2 categories. They are:
Talking of system software they are responsible for controlling, coordinating and managing the operations that are done through the hardware of the computer. One of the most important functions of system software is that it creates the platform for application software to work. In other words they become the interface between the application software and the hardware of the computer thereby concealing all the physical functions that are dome by the hardware. You may ask about the various system softwares that are available in the market. Here are the examples of a few:
Normally the function of system software is to convert and translate all the inputs taken from various sources into machine language. The more technical part is done by the operating system which organizes the different hardware components of the computer. In fact the system software is the most important part of the whole computer because it protects all the individual software applications that are there in the computer. Along with all this you can be sure of one thing and that is since the system software acts as the interface it will protect all the physical components too. In this way you will get a both side protection that would help your computer to work more efficiently than what it normally does. There are various operating systems that are there in the market. Some of them are as follows:
These are some of the most popular and they are in demand all throughout the year because of their ability to work both in difficult and simple conditions.

Before you buy a computer you must decide which operating system your computer should have and as the trend shows people have selected Linux since its inception. With advancement in the technology and with great capabilities Linux has become an essential operating system for many. Benefits of Linux operating system When there is so much demand for this operating system, then it certainly means that there are many advantages of using this. Here are some of the benefits of using Linux as your operating system: ü It is available free of cost as you can download the full software from the internet and then get it installed in your computer. ü As an operating system it is powerful enough and has the ability to outperform Windows operating system in various ways. ü Since this is very stable there are less chances of freezing or crashing down which the other operating systems have. This narrows down the chances of formatting your computer frequently. ü With Linux you will get a whole lot of software and that too for free. As the development of software is going on something new is being launched every day and it has already reached over 20000 and the best part is you will get them free of cost as they can be downloaded from the internet. ü After every 6 months there will be notifications for upgrading your system and this is also available for free. In fact if you want any updates for the new releases then also you will not have to pay a single penny. ü You may think that there might be threats of virus attacks or from hackers but that is where Linux is so unique. You will not need any kind of antivirus or firewall protection because the operating system is made in such a way that the hackers would not be able to figure out the process of hacking and by the time they do there will be another version which you can upgrade. ü If you have Linux then it is one of the wisest decisions because it is very user friendly and you can easily learn to work with this operating system within a few days.
The definition of software is very simple. It is a set of procedures, documentation and programs which performs various tasks in the computer. Basically the software in the computer acts as the brain of the whole system. Now software can be divided into two categories. They are:
a) Application software
b) System software
Application softwares are those that are designed in such a way so that the person who is using it can perform multiple tasks with it. Be it any kind of text manipulation or graphics or numbers or simply a combination of all these things an application software will be able to find a way for all these problems. Following are some of the examples of application software:
Procedure Of Developing Application Software
The ways and means of developing application software is similar to the process which the normal development of software follows. Here are some of the steps that are discussed below:
v Planning- this is the first step and here the demand for a particular service is discussed so that the management understand the utility of the software that is about to be made.
v Designing- this is the second step and the most important one. After the plans are set the developers make various debugging and testing for the software which they have decided to build.
v Testing- once the development of the software is done it is the responsibility of the developers to test it first before they launch it so that there are no disputes while working with the software.
v Implementation- this stage comes after the software has been launched. Basically this is a review stage where the developers get to know the response from the people who have used this software.
v Maintenance- this step is extremely important because the developers must proceed with the work they have done and that will give new versions of the same software with new features.
v Termination- this stage comes when the software has got out dated and people are no longer interested in sing that software anymore. It marks the end of that software’s life.

This is the second edition of John Zelle’s Python Programming, updated for Python 3. This book is designed to be used as the primary textbook in a college-level first course in computing. It takes a fairly traditional approach, emphasizing problem solving, design, and programming as the core skills of computer science. However, these ideas are illustrated using a non-traditional language, namely Python. Although Python is used as the language, teaching Python is not the main point of this book. Rather, Python is used to illustrate fundamental principles of design and programming that apply in any language or computing environment. In some places, I have purposely avoided certain Python features and idioms that are not generally found in other languages. There are already many good books about Python on the market; this book is intended as an introduction to computing. Features include the following: *Extensive use of computer graphics. *Interesting examples. *Readable prose. *Flexible spiral coverage. *Just-in-time object coverage. *Extensive end-of-chapter problems.

If your business relies on the use of IT equipment as most do these days, then it’s vital that you know how to clean them properly and thoroughly. For many businesses their computers are their most valuable asset and without them they would fail to function so it stands to reason that you should want to keep them in the best possible condition. You might be thinking that you can simply spruce them up with a cloth and some screen cleaning agent but to keep your computers in the very best condition and prolong their lifespan you need to learn how to clean them properly and luckily for you here are some top IT cleaning tips.
When it comes to cleaning IT equipment whether its laptops, desktops or printers, you need to get rid of the dust that inevitably builds up within them. Dust all of the outer components of the machines you use and get rid of any dirt that builds up. You can use a damp cloth containing cleaning alcohol to do this but make sure you don’t use the same cloth for the computer screen.
Screens need to be cleaned differently depending on their specifics, for example an LCD screen should be cleaned with a soft cloth which is dry, not moistened. You can use a moistened cloth and or screen wipes on other types of screens such as a CRT screen.
This might seem like an obvious point but it’s an important one as you need to understand what equipment needs cleaned and the different requirements involved. For example, you may have some very complex machines in a server room or data centre that needs some specialised server room cleaningattention. For such jobs it’s recommended that you hire a professional IT equipment cleaning agency who will know exactly how to clean complex equipment thoroughly and safely or alternatively you could hire someone in house to maintain the cleanliness of the machines.
If you are a particularly large company then you might want to roll out some instructions to your staff to educate them on how to clean their computers properly. This will save you having to hire a team to clean them for you but you must be careful that you give them the right guidelines to follow otherwise they could be doing more harm than good.
The key to marinating a clean office and highly functioning equipment is to clean them regularly, there’s no point in having a big cleaning operation once a year as that gives the dirt and grime a whole year to build up which is sure to cause problem within that time. This can lead to poor performance, machines stopping working all together and general disruptions to your working day. Clean your machines on a daily or at least weekly basis to keep them performing to the peak of their abilities and to keep your business operating as efficiently as possible.
Author Bio: James Anderson hired ECS, who are IT equipment cleaning specialists, to clean his server room computers and electrical equipment.
