SQL queries
The command used to display the customer ID and total number of orders placed is given below
Query:
SELECT CustomerID, COUNT (orderID) AS TotalOrders
FROM Order_Table
GROUP BY CustomerID
SELECT - To query the database and get back the specified fields SQL uses the select statement
CustomerID is a coloumn name
The function COUNT(OrderID) returns the number of orders
Totalorderds is a label
FROM - To query the database and get back the preferred information by specifying the table name
Order_Table is a table name
GROUP BY - The clause is used to group the result of a SELECT statement done on a table where the tuple values are similar for more than one column
The table below displays the CustomerID and total number of orders placed
CustomerID Totalorders
4 28
1 6
12 5
16 5
6 3
9 3
15 3
3 1
13 1
14 1
The table below shows the total number of orders situated for each sales person
SalesPerson_ID TotalOrders
3 16

Answer:
The expressions in each part of an AND or OR expression use <u>Short Circuit</u> evaluation; that is, they are evaluated only as much as necessary to determine whether the entire expression is true or false.
Explanation:
Logic operations follow different type of evaluation methods that can be short circuit or open circuit evaluation. In short circuit evaluation if first operand of the expression is true or false in OR or AND operation respectively, the result will found as true or false without checking the second operand of the expression. This is called Short Circuit Evaluation.
In OR operation, If first operand is true it means that the result of the expression is true without knowing that the other operand is true or false. In AND operation, If the first operand is False, the result will found as False without knowing that whether the 2nd operand is true or false.
This Mechanism is called Short Circuit Evaluation.
I am guessing "A" because you can store code anywhere and file structure does not prevent viruses.

Answer:
a. 1 is a packet, 2 is data, 3 is a frame.
Explanation:
And what is not mentioned is segment which used TCP/UDP and is part of Transport layer. The packet carries the destination and sender IP address, and is part of the Network Layer. The frame has the Mac address of destination device and senders device and is part of data link layer.
Hence segment has no IP address, hence b. is not correct. Also, data cannot have the IP Address, and Frame has the MAC address, Hence, the above answer. And this arrangement is part of Data Encapsulation.
Also keep in mind data can be anything like a series of bits, or any and it can or not have a header.
