Technology changes advertising and communications by increasing the outreach of people that will get the message, and increasing the speed at which they get the message. Which in turn makes the advertising more relevent because they can release more product to a wider audience during a specific time period.
Answer:
ALTER TABLE Products
ADD Products_price float(5,2) DEFAULT 9.99,
ADD Adding_time datetime;
Explanation:
So at first we need to use ALTER TABLE statement, when we use this statement we also need to provide the table name. In this case, i assume it is 'Products'.
Then, as per question, we need to add two columns.
The first one is 'product_price' and it contains decimal points. So, we need to use ADD statement and give a column name like 'Prodcuts_price' and its datatype 'float' because it contains decimal or floating points. so, for 3 digits on the left and 2 digits on the right, it makes a total of 5 digits. So, we need to declare it like this. (5,2) it means a total of 5 digits and 2 after the decimal point. after that, we need to set our Default value using the DEFALUT statement. so DEFAULT 9.99. it will set the default value to 9.99 for existing products.
And for our next column, we give its a name like 'Adding_time' then it's datatype 'datetime' because it will contain date and times.

Answer:
<em>C. Purging</em>
<em></em>
Explanation:
<em>Data Purging in computer storage is a process that permanently erases and remove data from a storage space</em>. Data deleting only removes the shortcut to the data but does not remove the data permanently, and can be easily recovered by an expert. <em>Data purging removes data permanently and also frees up the storage or memory space for other uses.</em> Data purging is relatively inexpensive and can be achieved with some special software tool.
Since the storage provider wants the hard drive back in working condition, data purging is the best option.
