Steps in program planning

Steps in program planning

No work is done well without proper planning. Therefore, to write a program, the program is completed through a well-planned step-by-step process. The steps in program planning are as follows


(1) Problem identification: The first step in program planning is problem identification. That is, identifying the program to be written for a problem according to the user's needs.

(2) System analysis: After identifying the problem, various information related to the problem must be collected and analyzed, which can be used in the next steps of the programming plan.

(3) Determining the input/output of the program:  At this stage, the inputs and outputs required to solve the problem are determined. Some data or information will be used as input in the program and what output will come for the said data, for this the use of some formula or formula is determined.

(4) Algorithm development: Once a complete understanding of a problem and its solution formula is available, the next task is to express in writing the successive steps in the order of solving the problem. That is to develop the algorithm for the program.

(5) Flowchart development: Before creating a program, the steps of how the program will work step by step is called a flowchart. Writing a program requires having a clear idea of ​​how the program will work. Sometimes when the size of the program is very large, it is convenient to make a flowchart. Just as a graph gives a clear idea about several years of data or information, a flowchart can easily understand the core functionality of a program. This allows the program to be analyzed by someone else, making programming easier and saving time. If a problem arises while programming, the problem can be solved by looking at the flowchart. Skilled programmers always create programs by creating flowcharts.

(6) Determination of programming language: The next step of creating a flowchart is a specific language for programming. In that case, some other kind of help can be taken. Note that some software companies prefer a particular programming language for a specific task. Sometimes it is recommended to take the programming language the hard way, such as assembler rather than choosing machine code, or choosing a high-level language. There are many programmers who choose a particular programming language by themselves to provide better working skills and better software.

(7) Writing the program (Program coding): In this step, the program is written using the programming language that has been selected for writing the programming.

(8) Compilation (Program compilation): The program written in high level language cannot be understood by the computer. The program written in high-level language has to be converted into machine language, i.e. compiled. A lot of compiling errors are found while compiling. Compiling can be done perfectly if you follow the instructions of the compiler.

(9) Program testing and debugging: Generally there are some errors in the initial stage. These can be due to various reasons. (Eg- due to lack of clear channel about program language and operating system, complexity of data etc.). These errors in the program are called bugs. The process of making these mistakes in the program is called debugging. These issues can be resolved with the help of appropriate commands. Various types of alpha test, beta test etc. are done before a program is marketed. All these tests are quite helpful in judging the correctness or accuracy of the program.

(10) Documentation: Documentation is the written description of the various stages of program planning such as algorithm, flowcha program coding, bugs, debug, results and instructions required by the user, etc., so that it is easy to solve problems later on. is

(11) Installation: Before satisfactory testing of the programs they are kept in the development library. After satisfactory test results, the programs are loaded into the production library. This library is called install. In many cases, this installation can be very complicated, but it is possible to get good results at this stage if done as a team.

(12) Maintenance: The last step in program planning is maintenance. Maintenance refers to minor changes and enhancements to the program for non-essential reasons. When any software comes to the market, a good one comes to the market. The number of versions of the software is constantly increasing. Software needs to be modified and upgraded for various reasons. In keeping with modernity, advanced versions are brought out. Many of the same software may not work on other operating systems. In that case, the software is later adapted to work on the new operating system.

What are the things to consider when buying a WiFi or broadband router for home, office, park and restaurant ?

Today we talk about What are the things to consider when buying a WiFi or broadband router for home, office, park and restaurant .I never like huge introduction about any topic . I always like very shortly introduce any-things to my viewers without any-type boring .So let's began the leanrning :- 1. Decide in advance how many devices you will use. 2. Decide how much space you need coverage. 3. Understand the structure of your home. WiFi signals become weak to penetrate the walls. That is why good coverage is not available. If you have a lot of walls in your house and you want to get coverage in the whole house, then you need a router with high power and wall penetration feature. 4. Decide what features you need in addition to the internet connection. Such as: - 4.1 3G 4G Modem Support- There are many routers that can use the modem. Those routers have a USB port and a one port so that broadband lines can be used. But remember that the modem must have the ability to auto-connect. Not...

What should the processor look at?

The things that we all should keep an eye on are the processor or not; 1. Clock speed 2. Number of course 3. cache memory 4. FBS 1. Clock Speed: It is also called GH2. All processors are written on. Clock speed means how fast your computer can work. That's what this signal means. The speed of the processor is known through this clock speed, how fast the calculation can be done. 2. Number of Cores: The more cores the processor has, the faster the processor can work. If I give an example to explain the matter, I hope you can understand it very easily. Suppose if a person had many hands, then he could do many things at the same time. That is, if we go to the market and buy a smartphone, then we will see what the configurations of the phone are. If we look closely at the configuration of the smartphone, we will see that Dual Core Processor, Quad Core Processor, Octa core processor, Hexa core processor, Deca core processor. This means that the dual core processor has two arms or cores, ...

What is transmission media? Introduction to different types of data transmission cables

Transmission media: When a PC communicates or wants to communicate with another PC, it has to take the help of some transmission media. The most commonly used media in the network are twisted pair cable, coaxial cable, fiber optic cable. Nowadays, the use of optical fiber is increasing greatly. Radio wave, microwave and infrared technologies are prominent among wireless media. Among these mediums, optical fiber has the highest data transfer speed. The type of medium used in a network depends on the type and location of that network. The connection system for exchanging information between the sender and the remote receiving end is called a channel. The means or methods used to implement the channel are called media. such as-- (i) Cable or wire. (ii) Common telephone lines. (ii) Radio waves. (iv) Microwave. (v) Geo-satellite systems etc. Cable or Wire: Cable is an important medium in data communication. Cables are generally used for data transfer over short range networking such as LAN...
