Technical Terms - Internet (A-Z) - VPI

What does VPI stand for in the context of ATM networking?

• Virtual Path Identifier

• Virtual Path Instruction

• Virtual Channel Identifier

• Virtual Protocol Interface

What is the purpose of a VPI in an ATM cell?

• Identify the path the cell should take to its destination

• Identify the source of the cell

• Identify the type of data in the cell

• Identify the error in the cell

How does the VPI work in conjunction with the VCI in an ATM cell?

• Compress the data in the cell

• Check the integrity of the data in the cell

• Encrypt the data in the cell

• Guide the cell as it passes through multiple ATM switches

What determines the size of a VPI in an ATM network?

• The speed of the network

• The location of the network

• The type of data in the cell

• The size and scale of the network

How does ATM routing differ from IP routing?

• IP packets have fixed paths in a network

• ATM cells have larger headers than IP packets

• ATM cells in a data stream all take the same route

• IP packets in a data stream can take different routes

What was a drawback of ATM networks in practice?

• High latency in data transmission

• Significant overhead due to small cell size and headers

• Limited scalability for high traffic

• Incompatibility with other networking technologies

Which networking technologies eventually took over the role of ATM networking?

• Fiber optic networks

• Satellite networks

• Ethernet and IP-based technologies

• Wireless networks

What was the main advantage of Ethernet and IP-based technologies over ATM networking?

• Lower cost of implementation

• Simplicity and better scalability for high traffic

• Higher security features

• Faster data transmission speeds

What grade level is this quiz suitable for?

• Grade 8

• Grade 10

• Grade 12

• Grade 6

How many bits are typically used for a VPI in a large ATM network?

• 4 bits

• 12 bits

• 8 bits

• 16 bits
