Stages:

Ø Defining and Analyzing Problem

          In this stage, a programmer studies the problem. He decided the best way to solve this problem. Studying a problem is necessary because it helps a programmer to decide about the followings things:

Things:
·        The facts and figures which are necessary for the development of the program.
·        The way in which the program will be designed.
·        The language in which the program will be most suitable.
·        What is the desired output and in which form it is needed, etc.

IT Expert Solutions provides the Some Steps To Develop A Computer Program!


Ø Designing the Algorithm:

      An algorithm is a sequence of steps that must be carried out before a programmer starts preparing his program. The programmer designs an algorithm to help visualize possible alternatives in a program.

Ø Coding or writing the program:

       The process of writing a program is a very important step in program development. In this step, an algorithm is converted into a program. The program consists of different steps given in the algorithm. A large number of programming language according to the nature of the problem.

Ø Testing Program:

        A program must be tested in the process of program development. This process verifies the accuracy of a program. The program is tested by executing it again and again. Different values are given as input and output is checked. The errors must be detected and corrected if the output is not correct. All bugs In the program are detected and removed during program testing.

Ø Final Program:

        When the program is finalized, its documentation is prepared. Final documentation is provided to the user. It guides the user how to use the program in the most efficient way. Another purpose of documentation is to allow some other programmer to modify the code if necessary. Documentation should be done in each step during the development of a program.

How Devices On A Network Communicate!

The devices on a network communicate by Communications Protocol & Network Standards.

Communications:

                  The communications protocols determine how devices on a network communicate. The term standard refers to a set of criteria or requirements that have been approved by a recognized standards organization or accepted as a standard by the industry. The American National Standards Institute (ANSI) and IEEE are two example of standard organization. IEEE develops networking standards. The standards are very important in the computer industry because they help hardware and software manufacturers to ensure that the products are compatible with other computing products.

IT Expert Advice provides the information about the Devices On A Network Communicate!

Network Standards:

                 Networks standards define how the devices in a network connection such as the types of cables or wireless technology used and the speed used on different types of networks. They also define how the devices communicate such as the communications protocols used.

Used:

·       Ethernet (802.3):

       Ethernet (802.3) is the most widely used standard for wired networks. It is typically used with LANs that have a star topology. It is inexpensive and easy to install and manage.
Ethernet standard does not specify any central computer or devices on the network when data can be transmitted. Each node attempts to transmit data when it determines that the network available to receive communication.

·        Token Ring:

         Token ring is a network standard that is typically used in LAN. It allows network devices to access the network by passing a special signal called token. The token is like a ticket. A device can transmit data over the network only if it has a token. Only one token is available in one network. That is why no collision can occur. But the data transmission rate is slow. When the computer wants to send a message, it
·        Gets the token.
·        Puts the data in the token.
·        Adds the address of receiving the computer.

·       TCP/IP:

         TCP/IP stands for Transmission control protocol/Internet protocol. It is the most widely used communication protocol today. It is used to transfer data over the internet and consists of two protocols. The Transmission control protocol (TCP) is responsible for the delivery of the data and internet protocol (IP) provides addresses and routing information.
TCP/IP uses packet switching to transmit data over the internet.

·       Bluetooth:

         Bluetooth is a network protocol that defines the method for transmission of data between two Bluetooth devices using short-range radio waves. The devices must be within a distance of 33 feet. However, the distance can be extended using additional equipment.
A Bluetooth device uses a small chip to communicate with other Bluetooth devices. Most of the current operating system has built-in support for Bluetooth.

·        Wi-Fi:

          WIFI is developed by IEEE and specifies how two wireless devices communicate over the air with each other. It is a family of wireless networking standards that uses IEEE 802.11 standard. There are various versions of the standard that support different speeds and distances. The common standards include 802.11a, 802.11b, 802.11g, 801.11nac, and 802.11ad. Most mobile and smartphones are Wi-Fi-enabled.
