The use of table two
Depending on the parameters of the table and cell, we can make the following table:
The above is a 3x2 table with a table width of 350 pixels, the width of each cell is 33%, which is one-third of the table, where cell 1 and cell 4 are merged, cell margins, cell spacing, table line widths are 10, the table has a gray color, and cell 5 has a red border. The background of

2-3-4 trees and red/black trees may look completely different. However, in a sense, the two are exactly the same.
There is a data item and two subnodes are called 2-nodes.
There are two data items and three sub-nodes called 3-nodes.
Three data items and four subnodes are called 4-nodes.

4-1.Python object. What are the three attributes related to all Python objects? Please briefly describe it.[Answer]All Python objects have three features: identity, type, and value.Identity: each object has a unique identity. The identity of any object can be obtained using the built-in function id. This value can be considered as the memory address of the object.Type: the object type determines what type of value the object can save, what operations
client, name/value pairs are a good choice because server and server-side languages can easily interpret name/value pairs, as well as using XML when returning data to a client. There are several ways to get the XML response from the server and use the more standard code to extract the data, which is used in the client.Listing 1. Server response (XML format)----to treat XML as plain textThe simplest choice for working with XML (at least in terms of learning new programming techniques) is to hand

as hardware raid, and features are not as good as hardware raid.
Next we will introduce various RAID technologies
I. RAID 0
The band technology is used to write data in parallel on multiple disks in bytes or bits (the starting offset of each disk is the same, and the subsequent segments of a certain number of bytes, i/O read/write performance can be improved, but it does not have data redundancy like raid1. Once the hard disk fails, it will be done. The structure is as follows.
