Which OSI layer is not present in broadcast networks?
Answer:
Network layer
In a simple broadcast network where all nodes are on the same segment, there is no need for routing, so the network layer is often absent.
1152
Which organization created the OSI model to allow diverse systems to communicate?
Answer:
ISO
The Open Systems Interconnection (OSI) model was developed by the International Organization for Standardization (ISO).
1153
The \_\_ layer allows users to access network services.
Answer:
Application
The Application Layer (Layer 7) is the OSI layer closest to the end user, which means it provides services directly to user applications.
1154
How many OSI layers are included in the X.25 standard?
Answer:
Three
The X.25 protocol covers the first three layers of the OSI model.
1155
which layer of OSI model used by router?
Answer:
layer 3
Routers are key devices that operate at the Network Layer (Layer 3) of the OSI model. Their main function is to forward data packets between different computer networks by using logical addresses, such as IP addresses, to determine the optimal path.
1156
The \_\_ layer is responsible for delivering the complete message from process to process.
Answer:
Transport
The Transport Layer (Layer 4) provides transparent transfer of data between end users, providing reliable data transfer services.
1157
Which device functions within the data link layer of a network?
Answer:
Bridge
A network bridge operates at the Data Link Layer (Layer 2) of the OSI model. It connects two or more network segments and uses the MAC (Media Access Control) addresses of devices to intelligently forward or filter traffic between them, reducing unnecessary traffic.
1158
Which OSI layer is responsible for delivering a message from one process to another?
Answer:
Transport
The transport layer provides end-to-end communication services for applications, ensuring process-to-process delivery.
1159
The \_\_ layer establishes, maintains, and synchronizes communication sessions.
Answer:
Session
The Session Layer (Layer 5) is responsible for opening, closing, and managing the session between end-user application processes.
1160
The \_\_ layer transforms data into a mutually agreed format for communication.
Answer:
Presentation
The Presentation Layer (Layer 6) formats or translates data for the application layer based on the syntax the application accepts.
