Such control over the information flow (information control) represents a fundamental way in which information systems can react and change in response to consumers’ actions, creating interaction between the information system and the consumer.

The central dogma: Instructions on DNA are transcribed onto messenger RNA. The central dogma of molecular biology describes the flow of genetic information in cells from DNA to messenger RNA (mRNA) to protein. It states that genes specify the sequence of mRNA molecules, which in turn specify the sequence of proteins.

Thus, during expression of a protein-coding gene, information flows from DNA → RNA → protein. This directional flow of information is known as the central dogma of molecular biology.

It consists of two major steps: transcription and translation. Together, transcription and translation are known as gene expression. During the process of transcription, the information stored in a gene’s DNA is passed to a similar molecule called RNA (ribonucleic acid) in the cell nucleus.

The flow of information follows from DNA, to RNA, to Protein.

Information can flow in four directions in an organization: downward, upward, horizontally, and diagonally. The size, nature, and structure of the organization dictate which direction most of the information flows. In informal firms, such as tech start-ups, information tends to flow horizontally and diagonally.

Successful IFDs should highlight gaps that need improvement, display inefficiencies in information, uncover and highlight risks to information such as data confidentiality and Insecure systems, display unsuitable mediums which are being used, and they should also provide clarity about who should receive which …

Information flow within an organization is extremely important in determining the success or failure of the business in the long run. This will ensure long-term growth, profitability, and sustainability of the business.

All data flow diagrams include four main elements: entity, process, data store and data flow.

A flowchart is a picture of the separate steps of a process in sequential order. It is a generic tool that can be adapted for a wide variety of purposes, and can be used to describe various processes, such as a manufacturing process, an administrative or service process, or a project plan.

Energy flow diagrams. Energy flow diagrams show what is happening to a particular type of energy as it is used or changed in some process or situation. Energy flow diagrams can be extended to include other forms of energy, such as light energy, electrical energy and heat energy.

(i) Should consist of standardized and acceptable symbols. (ii) The symbols should be correctly used according to flowcharts rules. (iii) Should have short, clear and readable statements written inside the symbols. (iv) It must have clear one starting point and one ending point.

Basically, a flow chart has the following features or part:

• Start of the project/ or task. This is denoted by an elongated circle.
• Instructions to be provided and actions to be done.
• Decisions that must be made as indicated by a diamond – shaped figure.
• Possible consequences of the decision as directed by arrows …

If the flowchart becomes complex, it is better to use connector symbols to reduce the number of flow lines. Avoid the intersection of flow lines if you want to make it more effective and better way of communication. It is useful to test the validity of the flowchart by passing through it with a simple test data.

One of the most important uses of flowcharts are to depict through images how a process is performed from start to finish, typically in sequential order. A process flow diagram is often used in training to document an existing process or to evaluate the efficiency of that process.

Answer: The uses of flowcharts are numerous in industries, such as entertainment, engineering, physical sciences, and computer programming.

Benefits of Flowchart Software

• Benefit 1: Improved Communication. Flowchart software empowers entire teams to collaborate as they create, edit, and analyze flowcharts.
• Benefit 2: Visual Clarity.
• Benefit 3: Effective Analysis.
• Benefit 4: Problem Solving.
• Benefit 5: Documentation.
• The Big Picture.

Flowchart – Advantages and Disadvantages

• Flowcharts are easier to understand compare to Algorithms and Pseudo code.
• It helps us to understand Logic of given problem.
• It is very easy to draw flowchart in any word processing software like MS Word.

Disadvantages of Flowcharts

• Alterations – Alterations can become a hassle when using flowcharts.
• Logic Complexity – When a process is relatively complex, this can make a process flowchart look messy and clumsy.
• Reproduction of a Flowchart – The last major drawback pertaining to flowcharts is that flowchart symbols cannot be typed.

The flowchart is a waste of time and slows down the process of software development. The flowchart is quite costly to produce and difficult to use and manage. Flowcharts are not meant for man to computer communication. If you need to modify or alternate the process then it will be very hard to do in the flowchart.

Flowcharts have many limitations, including oversimplifying, repeated modifications and reproduction. If you draw flowcharts by hand, it will be quite time and effort consuming. So it is advisable to rely on technology and use professional flowchart software.

1 : an act or instance of limiting. 2 : the quality or state of being limited. 3 : something that limits : restraint. 4 : a certain period limited by statute after which actions, suits, or prosecutions cannot be brought in the courts.

Algorithm is step by step procedure to solve the problem. Flowchart is a diagram created by different shapes to show the flow of data. In algorithm plain text are used. In flowchart, symbols/shapes are used.

Advantages and disadvantages of pseudo-code

• it can be quickly and easily converted into an actual programming language as it is similar to a programming language.
• it is fairly easy to understand, even for non-programmers.
• it does not matter if there are errors in the syntax – it is usually still obvious what is intended.
