The Oracle database uses undo to ensure consistent read and dirty read. User A updates the table and does not submit the table. User B queries the table, unsubmitted updates cannot appear in the user's query results. Instance simulation: the data in the test table is as follows: 1. User A queries: SQL> select * from test; id name ---------- -------- 1 A 2 B2, user B: update test set name = 'C' where id = 1; www.2cto.com 3 is not submitted, user A queries again: SQL> select * from test; id name -

. Address fields and control fieldsAfter the Flag field, you can have an address field a (addr) and a control field C (Contro1). The Address field is used to specify the address of the secondary station with which to communicate. A control field can prescribe several commands.The 1th or 1th, 2 bits in the control field represent the type of the transfer frame, and the 1th bit is "0" to indicate yesInformation Frame, 1th, 2 bits is "10" is the monitoring frame, "11" is no numbered frame.

In the network, the roles of both parties are SCP and SCU, while in the storage medium, they are only related to operations on the media.
