Computer Software
A software program is actually a set of instructions written in various computer languages by programmers.
Software contains sequences of operations the computer will follow.
Before a program can run or be executed, the program must be loaded into main memory of the computer.
After that, programs can be executed to perform certain functions based on how they are design.
For example, the word processing program allows users to enter their typing and edit the content.
A graphic design program is used to perform graphic designs.
Most computer programs are written by people with special training, called computer programmers, who write the necessary instructions in programming languages.
Software is the brains of the computer. It tells the hardware what to do.
In fact, it’s software that determines computer’s personality.

The Information Age
The Information Age
Managing a command and control organization depends on telling the workers what to do, then seeing that they do it.
It was easy to measure output and quality with a tangible product. Easy also to see if a manual worker was working hard or slacking.
But how do you supervise knowledge workers? If a designer or programmer is staring into space is he or she thinking about a work problem – or planning a holiday? How do you even measure the output or quality of the work as it is being done?
So, of you cannot control knowledge workers, can you command them?
Perhaps but only in broad terms, because the knowledge worker will b e closer to the action and therefore often knows better than the supervisor what needs doing.
Knowledge workers cannot perform well in the secrecy and mistrust of a traditional command and control environment.
They are best motivated by being given the problem and trusted with all the available information, then left to find a solution.
Instead of trying to command and control them, it is better to make sure you hire the right people, then inform and entrust them.
This is not an easy message to sell to chief executives, many of whom feel they are paid to call the shots, and there are still plenty of organizations with scope for better management of their knowledge workers.
However, there is also a growing band of new style organization that have abandoned the command and control model and the multilayer hierarchy.

The Operating System
The Operating System
The operating system (OS) consists of the master of programs that manage the basic operations of the computer.
These programs provide the control and use of hardware resources, including disk space, memory, CPU time allocation, and peripheral devices.
They are also the interface between computer hardware and application programs, allowing end users can concentrate on their own tasks or application rather than on the complexities of managing the computer.
To be more specific, the operating system is used to control the hardware memory, schedule the execution of programs, and schedule input output traffic between the CPU and other devices.
A good operating system, can dramatically improve the effectiveness and the efficiency of program execution performance.
Many different operating systems are available for computers.
Some operating systems are designed for a microcomputer single user environment, and others are for multiple users.
The complexity of operating system is much higher in a multiple user operating system due to the management of computer memory and CPU time shared by many users.
Today, many computers use what is called an operating environment, which provides end users with a user friendly interface to use.
Some operating systems have a graphical user interface that provide visual clues such as icons and objects the help the users.
Each icon represents a folder, an application package, or file. By clicking icons, users can open a folder or use an application package.

Business Intelligence Functionality
Business Intelligence Functionality
Business intelligence software is getting increasingly more powerful and although most of the popular solutions on the market share much common functionality, some might be easier to use or to offer more or fewer features than others.
Business intelligence software is getting increasingly more powerful and although most of the popular solutions on the market share much common functionality, some might be easier to use or to offer more or fewer features than others.
- The following list is some of the key features offered by many tools:
- Drill-down (on dimension such as time, company trees, products, etc)
- Graph, charting and trees
- Exception highlighting
- Pivot rows and columns
- Drag and drop dimensions into current view or to the backyard
- Custom calculations (calculate new measures based on existing ones)
- Queries
- Comments
- Combo views
- Dashboard
- Business intelligence and web portals
- Distribution of cubes/reports
- Other popular analytical features (ranking, filtering, sorting etc.)
