Computer software is the phrase used to describe a set of instructions, or a program, that lets a computer know what it is supposed to do. Hardware refers to things like the computers themselves, monitors, printers, disk drives and other pieces that are hard, meaning solid and tangible. Programs are not tangible and are given the name software. There are several types of software but the three most common are application, programming and system.

Operating systems, device drivers and utilities are all examples of system software. An operating system is basically like the commander of the computer and organizes all the activities that take place. One of its many jobs is to act as an interface between the user and all the hardware. Also, it distributes system resources for the application software.

Printers, monitors, keyboards and mice are devices that require a device manager. Each device has its own driver that stores all the information that the computer needs to run the device properly and to its fullest capacity. For instance, a keyboard driver gives the computer all the necessary info to recognize and properly carry out the function of each keystroke.

Utility programs have many functions. They are used to maintain and configure computers as well as optimize performance. Cleaning the registry, defragmenting, managing files, portioning the disks, compressing data and backup are common utility tasks. Utility software is almost always already installed on a computer before you buy it.

As the name suggests, programming software helps programmers write computer programs. Source code, or a human readable program, is written in object code, or a computer language. The result is a program. Debuggers are used to test out programs and fix and errors. Additional programming tools include interpreters and text editors.

Everyday tasks performed on a computer are run with application software. Every application a computer does is also referred to as a task. Even a game is a task, or application. When you take over the role of WWII hero, you are utilizing application software. You also use this type of software when you run medical, business, educational and scientific programs.

Companies use applications software everyday to aid with the needs of business. Spreadsheets, payroll, customer service, accounts receivable, inventory management and data base organization are all run with such software. A company may also invest in software that will teach employees to learn a second language to increase worker capability. Software is also used every day in hospitals to run some monitoring equipment. Researchers use it in their labs to test theories in modeling programs.

The software industry is expected to grow by over 50% by the year 2013. There are thousands of computer software companies all over the world and ten times as many programmers working to make the industry even bigger. Job seekers and investors realize how important this industry is and the pace at which it is expanding. It is little wonder that so many people are trying to get involved in this field in one way or another.

E-Learning is defined as an electronic learning. It is an improved and enhanced means of learning things in a better and convenient way. Earlier learning was subjected to older means such as reading books, sitting in a classroom or listening to teacher. But electronic learning provides all these things restricted to one click of the mouse at your own will. It entitles all the comfort you need to learn specific things at home or at any far flung place. It is a type of pedagogy that is totally user oriented. Internet plays a decisive role in providing you all the knowledge. It is the massive database of information and it is becoming more and more organized with help of technological advancements. Basically it acts as a “virtual learning environment”. Learners can determine how, what and when they can access information. You can have access to the information on the system using Internet at any time and at any place.

Tools of E-learning includes video tutorials, Pod casts, RSS feeds (termed as Rich Site Summary, it enables you to constantly receive the updated links to the websites chosen by you), blogs, email- newsletters and web conferencing. The future of learning resides in this form. E-Learning has its historic presence in way back 1840. At that time courses were provided through mail with the help of post offices but now it is the underground cables that are transmitting information at lightening speeds through internet and computers. This aspect of electronic learning helps various educational institutes to provide online degrees to the students.

The advantages of E-learning thrive upon its personalized approach, better quality and its cost – effectiveness. This form of method makes its users comfortable by allowing them to learn at their own pace. The goals and benefits of E-Learning include easy and increased access to information,convenience and flexibility to the learners. This method also improves the performance of individual and as well as of an organization. Organizations can learn how to increase their productivity and sales by referring to the tips given by experts. It also helps in organizing induction programs for the company. Evolution of internet will take this field of learning to new heights.

On of the best techniques to reference data in excel is to use named ranges. This can be extended if you want dynamic named ranges which adjust with new data.

Normally we hard code the source range for a chart or pivottable, especially if the full range is fixed for the year. However, if the final range is not fixed, then we have to manually update the range for the charts or pivottables every time the new data is added to the database or excel list. To update a pivottable manually, you need to select the table and then pivottable wizard, select back and then reselect the range. The source range also needs to be open.

You can use VBA code that opens up the source and updates the relevant pivottables automatically instead of having to do the above. If all the updating was left to the end, you could easily call all macros and update with one click!

However, in excel version 2003. A new data List feature provide dynamic lists. Another benefit is that there is no need to load the source file first as when using the OFFSET formula. The list range is usually given a named range. If you are using an older version then use the offset formula outlined below.

Once the formula or list range has been completed, go into the relevant pivottable and add the name of the dynamic range after the file name e.g. yourworkbook.xls’!yournamedrange

This means that when new data is added to the database, the named ranged should automatically expand to include the new data. When you refresh the pivot tables manually or by using the code, the pivot tables should now show the new data. This is a great way to start the development of an excel dashboard. Dynamic pivottables are a useful data model.

Go to: Insert>Name>Define and in the Names in workbook box type any one word name (I will use MyRange) the only part that will change is the formula we place in the Refers to box depending on if you are using offset or are using the list feature.

For the offset formula only use this:Expand Down as Many Rows as There are Numeric Entries.In the Refers to box type: =OFFSET($A$1,0,0,COUNT($A:$A),1)

If it is the data list you are using, then Go to: Insert>Name>Define and in the Names in workbook box type any one word name. Use this formula in the refers to box. Adjust the sheet name and range accordingly: =’yourworksheet’!$A$5:$G$339
