CDS 130 Test with Correct Answers
Computer science - ✅✅ the computer itself is the only object of inquiry (its
hardware, software, and operations)
Computational science - ✅✅ computer and its software become an instrument in
which we observe / investigate nature so that we can gain insight
In silico - ✅✅ by computer models
Do computers think - ✅✅ computers do not think, assume anything, remember
anything, or do anything without being told, they solely run programs
Program - ✅✅ set of data values, set of processes (algorithms) to do something
with the data, set of instructions (commands) to implement the process / algorithm
Machine language - ✅✅ talks directly w/ electronics + hardware
Operating system language - ✅✅ interfaces between the machine language +
human operator
Programming languages/apps - ✅✅ contains commands to do something
(scientific programming - Matlab)
, Matlab - ✅✅ app/envirnoment to write and execute programs
File - ✅✅ A collection of information that a computer can use to do something
(data, graphic, text) and is storage of data / programs
What do most file types begin with - ✅✅ instructions for the computer on how
to read the file
File compression - ✅✅ compression is a measure of how efficiently the
computer stores data
How are files stored - ✅✅ stored because the operating system divides the
storage into 'blocks' of space
Size 1 - literal bytes of data
Size 2 - bytes of data - the amount of storage blocks used
Floppy disk - ✅✅ holds 100K of data
Internal disk drive - ✅✅ optional, good ones hold 10 met and cost 175 and are
very slow
Cloud storage - ✅✅ file storage on the server of the provider, becomes shared
data once on the server
Network storage - ✅✅ file storage somewhere on the network
