Serialization delay and (1) delay are the two components of network delay that are improved by increasing bandwidth. Serialization delay, i.e. the amount of time it takes to put the (2) on the wire, and queuing delay (depth of the queue) are improved by increasing the (3) from a 128Kbps circuit to a T1. However, three other components of delay, routing/switching delay, distance delay, and protocol delay are components that can not be positively affected by an (4) in bandwidth. If the circuits are not over-utilized, then increasing the bandwidth to improve the (5) of the application will only result in an increased bandwidth with no positive effects on performance.

Serialization delay and (71) delay are the two components of network delay that are improved by increasing bandwidth. Serialization delay, i.e. the amount of time it takes to put the (72) on the wire, and queuing delay (depth of the queue) are improved by increasing the (73) from a 128Kbps circuit to a T1. However, three other components of delay, routing/switching deiay, distance delay, and protocol delay are components that can not be positively affected by an (74) in bandwidth. If the circuits are not over-utilized, then increasing the bandwidth to improve the (75) of the application will only result in an increased bandwidth with no positive effects on performance.

Serialization delay and（）delay are the two components of network delay that are improved by increasing bandwidth. Serialization delay, i.e. the amount of time it takes to put the（）on the wire, and queuing delay (depth of the queue) are improved by increasing the（）from a 128kbps circuit to a T1. However, three other components of delay, routing/switching delay, distance delay, and protocol delay are components that can not be positively affected by an （）in bandwidth. If the circuits are not over-utilized, then increasing the bandwidth to improve the（）of the application will only result in an increased bandwidth with no positive effects on performance.

Owners are to be responsible for loss of or damage to the goods or delay in delivery of the goods only in case the loss, damage or delay has been caused by the improper or negligent stowage of the goods.This means that ______．

A:Owners are to be responsible for loss or damage even such loss or damage is not caused bythe improper stowage B:Owners are only responsible for the loss or damage or delay caused by improper ornegligent stowage C:Both A and B are right D:Both A and B are wrong"
