The BIOS feature that enables a hard drive to read or write several sectors at a time is called IDE block mode
Explanation:
IDE block mode setting speeds up IDE drivers when enabled by allowing multiple sectors to read or write operations. This BIOS feature rushes up hard disk drive passage by transferring many divisions of data per interrupt rather than using the normal single-sector transfer mode.
This mode of transfer is known as block transfers. When block transfers are enabled, depends on the IDE controller, nearly 64 KB of data can be transferred per interrupt.
Answer:
1) SQL Server
SELECT Top 5 concate(first name,' ',last name) AS Full name, Current age AS Age, state AS Address, Phone number AS Contact number from actor ORDERBY Current age DSC ;
2) MySQL
SELECT concate(first name,' ',last name) AS Full name, Current age AS Age, state AS Address, Phone number AS Contact number from actor ORDERBY Current age DSC limit 5;
Explanation:
There two queries first having syntax works fine in SQL server and later with MySQL. All bold faced words are sql keywords. I assumed the tablename is actor as table name is not given if table name is any other replace actor with that name.
It was the whaling industry.
Whaling use to be the main source of oil that was used for fuel and
lighting in America which was based in the coastal communities of New England. It went into decline when oil was discovered
in 1859. Eventually it replaced whale
oil as a source of fuel and life.
