Engineers who are involved in product design and manufacture of computer-aided should have enough knowledge in circuit and auto cad electronic design.
<u>Explanation:</u>
He or she should have mother board, voltage in or out extra. Person who develops should enough knowledge on circuit design which capacitor, resistance and voltage and processor capacity.
Each design they have first simulates and tested and result should be recorded. On simulation test success design is made.
There is third party software also available for design the circuit and gives the tested results as report.
ALTER TABLE statement is used to modify "amount" column in the existing "orders" table
MODIFY (amount DEFAULT 250) is used to set the default value 250 of the "amount" column.
Therefore if the supervisor wants the amount column to be configured to accept a default value of 250, then "ALTER TABLE orders MODIFY (amount DEFAULT 250) " statement should be issued.
A subnet mask complements an Internet Protocol (IP). Thanks to subnet masks IP addresses can be identified because they seem to be all the same but the subnet mask avoids confusion. If four subnets are to be created for the IP 192.168.90.0 3 bits of that IP must be used to create the subnet resulting in 255.255.255.192. Then:
