cloud storage advantages and disadvantages

communication line is idle, it cannot be used by other users. Therefore, the channel utilization is low. ③ When the circuit is switched, the data is directly transmitted. It is difficult for terminals of different types, specifications, and rates to communicate with each other and to control errors during communication. (2) packet exchange: the Packet Exchange is a unit of data exchange. The packet carries information such as the destination address and source address, and uses the

the backup storage to write logs to the hard disk for submission. This can maximize the performance of different database data. Comparison between Oracle and SQL Server database images However, this solution also has some defects, most importantly, it has many restrictions. For example, you can only use standard servers. You can only use database snapshots to perform limited reports on backup servers. You can only use single and duplicate copies of d
