The data is raw material while information is organized, processed, refined and useful for decision making. Computer is used to convert data into information. Computer is also used to store information in the digital form.

The Stage Model of Memory
1. Sensory memory is the earliest stage of memory. During this stage, sensory information from the environment is stored for a very brief period of time, generally for no longer than a half-second for visual information and 3 or 4 seconds for auditory information. We attend to only certain aspects of this sensory memory, allowing some of this information to pass into the next stage - short-term memory.
2. Short-term memory, also known as active memory, is the information we are currently aware of or thinking about. In Freudian psychology, this memory would be referred to as the conscious mind. Paying attention to sensory memories generates the information in short-term memory. Most of the information stored in active memory will be kept for approximately 20 to 30 seconds. The amount of information that can be stored in short-term memory can vary. An often cited figure is plus or minus seven items. While many of our short-term memories are quickly forgotten, attending to this information allows it to continue on the next stage - long-term memory.
3. Long-term memory refers to the continuing storage of information. In Freudian psychology, long-term memory would be call the preconscious and unconscious. This information is largely outside of our awareness, but can be called into working memory to be used when needed. Some of this information is fairly easy to recall, while other memories are much more difficult to access. The ability to access and retrieve information from long-term memory allows us to actually use these memories to make decisions, interact with others and solve problems.

The software for a computer system is often more expensive than the hardware. Yet this expensive software is all too easy to copy. Crooked computer experts have devised a variety of tricks for getting these expensive programs printed out, punched on cards, recorded on tape, or otherwise delivered into their hands. This crime has even been perpetrated from remote terminals that access the computer over the telephone.

Computer programs are called software. Software is instructions for hardware (the machines) to do work. Software is often divided into two categories:
Systems software: the operating system and all the utilities that enable the computer to function.
Applications software: programs that do real work for users. For example, word processors, spreadsheet programmes, and games are applications software.
