Basic Knowledge of Information (Computer)

Data is facts or different substances. related to the work performed It can be a number or a text that arises from the operation. or obtained from other agencies. cannot be used for immediate decision-making. It can only be used after processing.

Information is information that has been processed . Either simple methods such as averaging or more advanced techniques may be used. such as research, operations, etc., in order to change the general state of information into a relational form. or related To be useful in decision making or to answer various problems. Information consists of data, documents, sounds or images, but arranges the subject matter in a meaningful form. Information is not limited to numbers alone.

Data Properties

Storing data requires effort and determination. Or in other words, the acquisition of information that will be used.

Benefits Organizations need to invest both in terms of data, machines and equipment, as well as personnel development to support for effective use Information system management must take into account these issues. and try to look at the problem in a realistic , actionable way. Effective, worth the investment Therefore, the operation to obtain good information.

The data must have the following basic properties :

1. Accuracy – If data is collected and then it is unreliable, it will be very detrimental. The user did not dare to refer. or take advantage which causes the management’s decisions to be inaccurate. and maybe prone to errors. The designed data structure must take into account the operational processes in order to achieve the highest accuracy. Usually a mistake most of the information It comes from inaccurate information that may be caused by humans or machines. therefore the system design must be taken into account in this regard

2. Fast and up-to-date – The acquisition of information is necessary to keep up with the needs of users. There is a quick response to users, interpreting information in a timely manner or need. A learning system is designed. and report by the user

3. Integrity – The completeness of information also depends on the collection of information and practices. in the preparation Informatics must explore and inquire about the need for information in order to obtain information to a certain degree of completeness that is appropriate.

4. Clarity and compactness – Storage of large amounts of data requires a lot of storage space, so it is imperative to design a compact, meaningful data structure. Data is used appropriately or shortened in order to store it in the computer system .

5. Consistency, needs are important. Therefore, there must be a survey to find the needs of agencies and organizations to look at data usage conditions. The depth or width of the data boundary corresponds to the requirement.

Information Making

Making information into information that will be useful to use. Requires technology to help in the operation. It starts with collecting and verifying information. Processing of information into information and maintenance of information for use

1. Collecting and verifying information should consist of

1.1 Data Collection It is a matter of collecting large amounts of information. and must be kept in a timely manner, such as student enrollment information personnel history information Currently, there are many technologies that help in storing information such as entering data into a computer. Reading data from bar code Checking the blacklisted registration certificates in different locations is also a method of collecting information.

1.2 Data verification Once the data has been collected, verification is required. to check the correctness Information stored in the system must be reliable. If an error is found, it must be corrected. There are several methods of data validation, such as using two inputs to input the same set of data into a computer and compare them.

2. Processing of data into information It may consist of the following activities:

2.1 Data sharing The data collected must be segregated. to prepare for use There are clear methods of segregation, for example school information is divided into student profiles. and registration file The yellow pages of the telephone directory are categorized by products and services for easy searching.

2.2 Defragmentation when grouped into files Data should be arranged in alphabetical, numerical, or alphabetical order, or for easy retrieval and time-saving. An example of an arrangement would be to arrange the author information card in the library’s card cabinet in alphabetical order. Sorting people’s names in the telephone user directory make it easy to find

2.3 Conclusion Sometimes there is a large amount of data stored. A summary or summary report is required. to take advantage This summarized information may be more meaningful. such as statistics on the number of students separated by each class

2.4 Calculations The data collected is large. Some of the data is numerical data that can be calculated to obtain certain results. Therefore, the creation of information from the data also relies on calculating the stored data.

3. Maintenance of information for use consists of

3.1 Data retention Data retention means storing information on a recording medium such as a memory card. It also includes care. and make a copy of the data to be able to continue to use in the future

3.2 Searching for information The stored data is intended to be used in the future. Searching for information must be accurate and fast , so computers are used to help in the work. make the retrieval action timely

3.3 Data duplication Making a copy in order to keep the information or to be distributed later Therefore, data should be stored easy to copy or can be used again easily

3.4 Communication Information must be easily distributed or transmitted to remote users. Information communication is therefore important and It plays an important role in making the delivery of information to users fast and timely.
