CPS 310 EXAM || A+ Guaranteed.
LIFO correct answers Last in first out.
Stack pointer stores the address of the topmost data in the stack.
How code is made correct answers 1. Source code is given to compiler
2. Compiler checks code for syntax errors
3. Compiler converts code to object code
4. Linker makes it into an .exe file
5. Loader puts .exe into RAM.
Linker correct answers Software program that combines together separately assembled object
code into one program.
Loader correct answers A program that loads an executable program into RAM.
Interpreter correct answers Begins execution before converting the entire program. Each line of
code is translated one at a time.
Compiler correct answers Checks code as a block and translates it into machine code.
Syntax error correct answers Occurs when an instruction does not follow the syntax rules or
grammar of the programming language.
Semantic error correct answers (i) Logical error (not the result you expected to get)
(ii) Runtime error (program crashes)
What is the type of error that a compiler has never been able to solve? correct answers
Semantical error
.obj file correct answers Object code file (0 and 1)
Primary memory devices correct answers RAM (Random Access Memory)
ROM (Read Only Memory)
PROM (Programmable Read Only Memory)
EPROM (Erasable Programmable Read Only Memory)
Are faster and smaller compared so secondary memory devices.
Secondary memory devices correct answers Hard drive, floppy disk, CD (Compact Disc), USB
(Universal Serial Bus)
1 nibble correct answers 4 bits
1 byte correct answers 8 bits
, half-word correct answers 16 bits / 2 bytes
word correct answers 32 bits / 4 bytes
double word correct answers 64 bits / 8 bytes
quad word correct answers 128 bits / 16 bytes
What is always added to the end of a string? correct answers a null character
Pointer correct answers Points to the address of a given memory location.
True or false:
Once you delete a variable in a program, the value that was in that memory location is deleted
also. correct answers FALSE
A memory location will stay at it's last value until some other object occupies that memory and
writes a value there.
Deleting a variable in a program simply tells the compiler "I don't need this anymore", but it still
remains until overwritten.
What will the symbols "& x" yield? correct answers Will give the address of x.
= correct answers assignment operator
When you open and close your program, will the address of your variables stay the same or will
they change? correct answers The address will change when you open up the program again.
* correct answers Symbol for Pointer. It is a unary operator (operation with only one operand).
Scalar variable correct answers another name for a simple variable
Pointer variable correct answers A variable that holds an address
True or false:
Pointers take up less space in memory correct answers TRUE
Pointers take up less space in memory.
Endian correct answers Refers to the order of storing bytes in a computer's memory.
Big endian correct answers Least significant byte has highest address (occur last)
Most significant bit has the lowest address.
E.g.
Two bytes Stored: 34 62 → Value: 0x62 34
Four bytes Stored: 56 78 9A BC → Value: 0x56 78 9A BC
