Question

The Open Systems Interconnection (OSI) Reference Model: defines standards for many aspects of computing and communications within a network. is a generic description for how computers use multiple layers of protocol rules to communicate across a network. defines standards for wireless local area network (WLAN) communication protocols. details the advantages and disadvantages of various basic network cabling options.

Answer 1

The OSI Reference Model is a framework that standardizes the functions of telecommunication systems, allowing different technologies to communicate across a network. It does not specifically address WLAN protocols or network cabling options. The model played a crucial role in the historical development of the Internet and global communications.

Step-by-step explanation:

The OSI Reference Model and Its Role in Computer Networking

The Open Systems Interconnection (OSI) Reference Model is a conceptual framework that standardizes the functions of a telecommunication or computing system without regard to its underlying internal structure and technology. Established in the late 20th century, the OSI model is a generic description for how computers use multiple layers of protocol rules to communicate across a network. This model facilitates interoperability between different products and software. The OSI model has been instrumental in the development and design of communication networks since the advent of computer networking.

The OSI model is divided into seven layers, each with specific functions and protocols that interoperate to complete the communication process. From physical data transmission to application-level functions, it defines a standardized approach that supports the creation of network-agnostic communications.

An integral part of the historical expansion of communication protocols, the OSI model has played a significant role in governmental and business spheres by enabling a technological foundation that supports a robust global economy. Its importance was reflected during the massive adoption of uniform protocol systems across the United States, Europe, and other developed countries that ultimately led to the creation of the commercial internet.

The OSI model does not specifically define standards for wireless local area network (WLAN) communication protocols, nor does it detail the advantages and disadvantages of various basic network cabling options. Its purpose is to serve as a universal reference model for protocol design and to understand the communication processes.

Answer 2

is a generic description for how computers use multiple layers of protocol rules to communicate across a network.

Step-by-step explanation:

OSI model stands for Open Systems Interconnection. The seven layers of OSI model architecture starts from the Hardware Layers (Layers in Hardware Systems) to Software Layers (Layers in Software Systems) and includes the following;

1. Physical Layer.

2. Data link Layer.

3. Network Layer.

4. Transport Layer.

5. Session Layer.

6. Presentation Layer.

7. Application Layer.

Hence, the Open Systems Interconnection (OSI) Reference Model is a generic description for how computers use multiple layers of protocol rules to communicate across a network.

Additionally, each layer has its unique functionality which is responsible for the proper functioning of the communication services.
