What do parameters used in a procedure provide?

• A way to get values into the procedure making code more flexible.

• A way to return values calculated in the procedure back to the calling program.

• A way to call a procedure from within another procedure.

• A way to connect an API on the procedure.

What is an issue that organizations do NOT need to handle when dealing with large datasets?

• Ensuring enough staff are on hand to process the data.

• Ensuring the bandwidth can handle the processing of the data.

• Ensuring that people's private data is now exposed.

• Ensuring the system can scale down after the data are sent to the cloud.

How does the Internet work with the different equipment in use?

• The routers adjust for the different equipment manufacturers by sending data on the same equipment brands.

• Specific companies are approved to make equipment for the Internet.

• Vendors follow the protocols established to enable data to be sent and received across any equipment.

• The server farms handle the data once the data reach the Regional ISP.

What does scalability mean?

• The ability to build additonal functionality into the hardware.

• The ability to build additional functionality into the software.

• The ability to add more features to the hardware.

• The ability to add or remove resources as the size changes.

How are list elements accessed individually?

• The list name plus an integers index in brackets are used.

• The list name is used along with the value the code needs to access.

• The "access" command is used with the list name and length.

• A FOR EACH loop is used with the list to find an individual value.

What do logical conditions always evaluate to?

• A Boolean value

• A value stored in a constant

• A "string" text field

• A real number

There are many programming languages. How do computers understand the different languages?

• Testing takes care of this for computers by confirming the correctness of the code.

• Debugging handles this for computers by confirming the validity of the code.

• Compilers and interpreters translate the code to machine language for computer to read.

• There is a special natural language tied in to all programming language that all computers can read that is created behind the scenes using abstractions.

Why is there a need to find different algorithms for problems that already have a solution?

• Different algorithms could be more efficient

• Different algorithms could use heuristics rather than precise values

• Different algorithms could use frequency analysis

• Different algorithms could provide intractability.

What is the most common way computer viruses are spread?

• By people clicking on an infected file

• From pop-up ads

• Through network worms

• From random hotnet attacks

How does documentation help with maintaining programs?

• It journals the history of program changes showing how the program first worked before changes.

• If code is modified, the documentation can guide the programmer in testing to ensure the functionality is still correct.

• It documents how to run the program in multiple languages for a global audience.

• It is useful for training new employees on how to learn the programming language.
