Exercise #.3

1. Differentiate data and information. Give an example about your course.

ans. 

There is a subtle difference between data and information. Data are the facts or details from which information is derived. Individual pieces of data are rarely useful alone. For data to become information, data needs to be put into context. 

Example:

As a futures Manager the data that they can contribute to the company is the wise idea and decision. The brilliant idea of manager is a information that can be result to the successful of the company.

2. State the attributes of a quality information. Choose at list three attributes and provide an example of each.

Ans. 

Availability of a system is typically measured as a factor of its reliability - as reliability increases, so does availability. Availability of a system may also be increased by the strategy on focusing on increasing testability & maintainability and not on reliability. Improving maintainability is generally easier than reliability. 

ex.

For example, a unit that is capable of being used 100 hours per week (168 hours) would have an availability of 100/168. However, typical availability values are specified in decimal (such as 0.9998). In high availability applications, a metric known as nines, corresponding to the number of nines following the decimal point, is used. In this system, "five nines" equals 0.99999 (or 99.999%) availability.

Compatibility the state of being compatible in which two or more things are able to exits or perform together in combination without problems or conflict.

ex. 

Telecommunications the capability of two or more items or components of equipment or material to exists or function in the same system or environment without mutual interference.

Testability is a measure of how easy it is to create test criteria for the system and its components, and to execute these tests in order to determine if the criteria are met. Good testability makes it more likely that faults in a system can be isolated in a timely and effective manner.

Example:

 A hypothesis one of the good example is testable if there is some real hope of deciding whether it is true or false of real experience. Upon this property of its constituent hypotheses rests the ability to decide whether a theory can be supported or falsified by the data of actual experience. If hypotheses are tested, initial results may also be labeled inconclusive.

3. Explain how computer works.

 

This is the layout of how computer works.

There's a three component how computer works it is compose by input which is the data itself then the processing which the one derived the data and lastly the output which is the output of the process. The input it is the device of keyboard and mouse, the output can also refer to the projector, screen and printers. The processing compose of two storage one is the primary which is the RAM that are temporary only then the

secondary storage holds permanent or semi-permanent data on some external magnetic or optical medium. the diskettes and CD-ROM disks that you have seen with personal computers are secondary storage devices, as are hard disks.

 In terms about our course as a business management we have also a layout how business flow efficiently and sufficient. As an input, the inputs are the raw materials for creating a good quality products. As the process of that are the labors who work for it to ensure the products are in quality. The outputs are the finish product ready to served to the customer to satisfy their needs and wants.
