kvasek [131]

Answer:

When we journey from a particular city to another city and we don’t really know the path then we ask for path and go on that which is just the same thing as packet switching.

Explanation:

Suppose system A intends to send packet to system B the steps and procedures are given below

1. A breakdown of large file into smaller bits of data on system A will first occur.

2.It attach separate headers for every portion of the file so that each portion looks like separate packet.

3.Header file in chunks will contain ip address of the file receiver which here is system B.

Do the following SQL questions. The resulting columns must all have descriptive names. You must show the result of the query. Fo
Maslowich

Answer:

We can use CREATE command to create tables with columns having descriptive names

Explanation:

Firstly, create a table using CREATE  command in SQL. The syntax is as follows:

CREATE TABLE [table_name]

(

 [col_name] [datatype]),

[col_name] [datatype]),

[col_name] [datatype]),

[col_name] [datatype])

)

Once the table is created, we can insert the data into table using INSERT command. It's syntax is as follows:

INSERT INTO table_name VALUES('', '', '')

if datatype is string, values must be entered within single quotes. If datatype is int, values are entered directly without using  quotes.

Now, you can select the data from  the table using SELECT command. It's syntax is as follows:

SELECT column-list FROM table_name

If you want to filter rows according to conditions, you can use WHERE command.

I have created  sample table and inserted some data into it. Now, I applied some queries on it to select data from the table.

I have written in a text file and attached the same. Please find. Thank you!
