ISO-OSI-layers
Question 1 |
What is the main reason for developing ISO/OSI model for networks?
Manufactures disliked the TCP/IP protocol suite | |
The rate of data transfer was increasing exponentially
| |
Standards were needed to allow any two systems to communicate
| |
None of the given options
|
Question 1 Explanation:
The main reason for developing the OSI model for networks is to create a common platform for software developers and hardware manufactures that encourage the creation of networking products that can communicate with each other over the network. To help network administrators by dividing large data exchange process in smaller segments.
Question 2 |
Which layer functions as a liaison between user support layers and network support layers?
Network layer | |
Physical layer | |
Transport layer | |
Session layer |
Question 3 |
In OSI model, data compression is carried out by
Network layer | |
Physical layer
| |
Data Link layer
| |
Presentation layer
|
Question 3 Explanation:
Data compression and expansion is carried out by presentation layer.
Question 4 |
Project 802 defines standards for which layers of the OSI Models?
Application and Presentation layers
| |
Physical and Data Link layers | |
Network and Data Link layers
| |
Transport and Network layers
|
Question 4 Explanation:
Project 802 defined a family of low-level protocol standards at physical and data link layers of the OSI model.
