What is a network standard

Network standards are set by commissions as a set of ground rules for hardware so it can have compatibility with some network devices and to also assure interoperability it does this to allow vendors to have backward compatibility and compatibility with each other. It is important that we networking standards as well as standards because of their ability to allow communication between different devices from different manufactures with different software thanks to this networking is possible.

Standards organizations

IEEE is the Institute of Electrical and Electronics Engineers established in 1984 they are a professional technical association that are of a non-profit organization. Their standards mainly revolve around industries of electronics and computers.
ISO is the International Organization for Standardization founded in 1947 they are a national network spanning 157 countries of standard institutes. Their standards help promote development of the agreements of international standards.
IAB is the Internet Architecture Board established in 1979 but going under the name ICCB they are a committee of advisory bodies that oversee the engineering and development of the internet.
IEC is the International Electrotechnical Commission founded in 1906 they are an organization that works on a global scale so there for their standards are for all electrical and electronic technologies around the world.
ANSI is the American National Standards Institute they were founded in 1918 and are a non-profit organization that is restricted to the US so that means they are a private organization as well. Their standards is to establish a census among certain groups of users.

OSI and TCP/IP Models

OSI stands for Open System Interconnect and was developed in 1978 by OSI it defines how each device connected to a network communicates with one another through a seven layer system that directs the right data to the right device plus this model also ensures the interoperability between each network device. Today most network vendors use this type of framework to build their products.
TCP/IP stands for Transmission Control Protocol/Internal Protocol was created in 1978 but today it’s the dominant standard for communicating data between all computer networks that are on the internet. It is actually two separate protocols that work together so the Transmission Control Protocol ensure reliable data transmissions across all networks that are connected to the internet but the Internet Protocol section decides where in the network certain data packets will be sent to.

The OSI Model Layers

1. Physical this layer will define all specifications that are electrical and physical for the devices
2. Data Link this layer provides the media access procedures and the physical addressing
3. Network this layers purpose is to deal with logical addressing and like data link it deals with media access control
4. Transport this layer deals with the transportation and the flow control across the entire network.
5. Session this layer must manage and dispose of connections that are between the local and remote applications.
6. Presentation this layer will convert formats of data so it can provide the application layer with a standard interface.
7. Application this final layer is responsible for the networking services to the applications
