Test: Reference Models - 1 - Question 1

 OSI stands for

Detailed Solution for Test: Reference Models - 1 - Question 1

The term OSI refers to the Open System Interconnection model, which is a framework used to understand and implement network protocols in seven distinct layers.

  • The OSI model helps in standardising network communication functions.
  • Each layer of the OSI model serves a specific function and communicates with the layers directly above and below it.
  • This model aids in troubleshooting network issues by isolating problems to a specific layer.
Test: Reference Models - 1 - Question 2

The OSI model has _______ layers.

Detailed Solution for Test: Reference Models - 1 - Question 2

The OSI model consists of seven layers.

  • Each layer has a specific function within network communication.
  • The layers help standardise interactions between different computer systems.
  • This model facilitates interoperability across diverse networking technologies.
Test: Reference Models - 1 - Question 3

TCP/IP model does not have ______ layer but OSI model have this layer.

Detailed Solution for Test: Reference Models - 1 - Question 3

The TCP/IP model does not include certain layers that the OSI model does. Specifically, the OSI model has the following layers absent in TCP/IP:

  • Session Layer: Manages sessions or connections between applications.
  • Presentation Layer: Formats data for the application layer and handles encryption and compression.

Both of these layers are part of the OSI model but not present in the TCP/IP model.

Test: Reference Models - 1 - Question 4

Which layer links the network support layers and user support layers

Detailed Solution for Test: Reference Models - 1 - Question 4

The Transport Layer is crucial because it serves as a link between the network's support layers and the user's support layers. Key functions include:

  • Guaranteeing reliable data transfer between systems.
  • Managing error detection and correction.
  • Controlling data flow to prevent congestion.

This layer ensures that applications can communicate efficiently over a network.

Test: Reference Models - 1 - Question 5

Which address is used in an internet employing the TCP/IP protocols?

Detailed Solution for Test: Reference Models - 1 - Question 5

In a network using TCP/IP protocols, several types of addresses are employed:

  • Physical Address: Also known as the MAC address, this is used to identify devices at the hardware level.
  • Logical Address: This refers to the IP address, which is used to identify devices on a network.
  • Port Address: This is used to identify specific processes or services on a device.

Therefore, the correct answer is that all of these addresses are used in TCP/IP networks.

Test: Reference Models - 1 - Question 6

TCP/IP model was developed _____ the OSI model.

Detailed Solution for Test: Reference Models - 1 - Question 6

The TCP/IP model was developed before the OSI model. Here are some key points:

  • The TCP/IP model was introduced in the 1970s.
  • The OSI model was developed later, in the 1980s.
  • TCP/IP is more commonly used than the OSI model in practical networking environments.
Test: Reference Models - 1 - Question 7

Which layer is responsible for process to process delivery?

Detailed Solution for Test: Reference Models - 1 - Question 7

The transport layer is responsible for process-to-process delivery within a network. It ensures that data is transferred from a process on one device to a process on another device.

  • Reliable delivery: This layer ensures data is delivered accurately and in the correct order.
  • Flow control: It manages the pace of data transmission between devices to avoid congestion.
  • Error control: The transport layer detects errors in data transmission and requests retransmission if necessary.
Test: Reference Models - 1 - Question 8

Which address identifies a process on a host?

Detailed Solution for Test: Reference Models - 1 - Question 8

A port address identifies a specific process on a host. Here's why:

  • Port addresses are used in networking to specify particular applications or services within a device.
  • They work alongside IP addresses to direct data to the correct application.
  • Each application listening on a network has a unique port number, ensuring data is received by the correct process.
Test: Reference Models - 1 - Question 9

Which layer provides the services to user?

Detailed Solution for Test: Reference Models - 1 - Question 9

The application layer is responsible for providing services to users. Here are some key points about this layer:

  • It is the top layer of the OSI model.
  • It facilitates communication between software applications and network services.
  • Examples of its services include email, file transfer, and web browsing.
Test: Reference Models - 1 - Question 10

Transmission data rate is decided by

Detailed Solution for Test: Reference Models - 1 - Question 10

The transmission data rate in a network is determined by specific layers of the network architecture.

  • The physical layer is responsible for deciding the data rate. It manages the electrical, optical, or radio signals that transmit data.
  • This layer ensures that the correct speed and medium are used for communication.
