1. Name three different levels of the computer memory.

   Answer: Register (L1 Cache), L2 Cache, L3 Cache, RAM (Random-Access Memory), HDD (Hard Drive Disk).

2. Suppose that you have a matrix of rank 2 to store in the computer memory. How would each one of the following languages store this matrix (column-wise vs. row-wise):
   b) C
   a) Fortran
   c) MATLAB
   d) Python

   Answer:
   a) row-wise
   b) column-wise
   c) column-wise
   d) row-wise

3. What are the three fundamental components of a Turing-complete language?

   Answer:

   1. a way for accessing the memory
   2. a way for iteration
   3. a way for branching

4. What are the three common types of errors in computer programs?

   Answer:

   1. syntax errors
   2. runtime errors
   3. semantic errors

5. Suppose you write a program that has memory leak. What type of programming error you dealing with?

   Answer: runtime error

6. What is the biggest integer (in base 10) that you could store in an int32 type?

   Answer: 2,147,483,647

7. What is the difference between int16 and uint64 types (two major differences is enough)?

   Answer:
   1) int16 is only 16 bits storage, whereas uint64 is 64 bits storage.
   2) int16 is a signed integer storage meaning that one bit is reserved for the integer’s sign representation, whereas uint64 can only represent positive integers.
