The RAID type that utilizes mirrored striping, providing fast access and redundancy is RAID 10.

RAID 10 combines the features of RAID 1 and RAID 0 to provide both mirroring and striping. The data is striped across multiple disks, which provides fast access times, and each disk in the array is mirrored, which provides redundancy in case of a disk failure.

RAID 10 requires a minimum of four disks and provides excellent performance and fault tolerance, but it is more expensive than other RAID configurations because it requires more disks.

RAID 1, on the other hand, uses disk mirroring without striping, so it provides redundancy but not increased performance. RAID 3 uses byte-level striping with a dedicated parity disk, while RAID 5 uses block-level striping with distributed parity. Both RAID 3 and RAID 5 provide a good balance of performance and redundancy, but they have some drawbacks such as the performance penalty when rebuilding a failed disk.

Pipelined network protocols are used every day by web browsers to improve the efficiency of data transfer. In this response, we will discuss the relationship between pipelining and window size, as well as why longer RTT's on high-capacity network links can hinder reliable data transfer protocols.

Pipelining is a technique used in network communication to improve data transfer efficiency. It involves breaking data into smaller chunks, or packets, and sending them sequentially through the network. Window size, on the other hand, refers to the maximum number of packets that can be sent without waiting for an acknowledgement from the receiver. The relationship between pipelining and window size is crucial. Pipelining allows for multiple packets to be in transit simultaneously, which can improve overall throughput. However, the window size must be set appropriately to prevent congestion and ensure reliable data transfer. Regarding longer RTT's on high-capacity network links, the time it takes for a packet to travel from sender to receiver can significantly impact data transfer protocols. If the RTT is longer than the expected time for a packet to be acknowledged, the sender may send additional packets before receiving an acknowledgement. This can cause congestion and lead to packet loss, reducing overall throughput and hindering reliable data transfer protocols.

In conclusion, pipelining and window size are closely related and must be carefully managed to ensure efficient and reliable data transfer. Additionally, longer RTT's on high-capacity network links can negatively impact data transfer protocols and should be taken into consideration when designing and implementing network communication systems.

The given statement is that the supply of a product is inelastic in the $6-$5 price range. To assess the accuracy of this statement, let's understand the concept of supply elasticity and evaluate it using the available data. Supply elasticity is a measure of the responsiveness of the quantity supplied of a good to a change in its price. It can be calculated using the formula:

Elasticity of Supply (Es) = (% change in quantity supplied) / (% change in price)

An inelastic supply indicates that the quantity supplied does not change significantly when the price changes. Mathematically, this means the value of Es is less than 1.

To determine if the supply is inelastic in the $6-$5 price range, we need to compare the percentage changes in both the price and quantity supplied. Since we do not have actual data to calculate these values, we cannot confirm whether the supply is inelastic in this price range.

However, it is worth noting that factors such as production costs, availability of resources, and the nature of the good can influence the elasticity of supply. For some products, supply might indeed be inelastic within specific price ranges, as changes in price might not significantly affect the quantity supplied.

In conclusion, without concrete data, we cannot accurately determine if the statement is true or false. To provide a definitive answer, more information on the product's supply and price changes is needed.
