Single Contiguous Memory Management - CORRECT ANSWER=a memory management
method where all processes are loaded into a single contiguous block of memory
fixed partition technique - CORRECT ANSWER=Main memory is divided into a fixed number
of partitions into which programs can be loaded.
Best uses:
-Fixed workloads
-well-suited for batch processing
Worst use cases:
-cannot handle unpredictable workloads
-can lead to internal fragmentation
-limited flexability
dynamic partition technique - CORRECT ANSWER=The memory management technique in
which memory is divided into partitions as needed to accommodate programs
Best uses:
-Handling large unpredictable data
-Data that grows over time
Worst Cases:
Small sized data- hindering performace from unncessary complexity
-added complexity of managing the system

Single-partition allocation - CORRECT ANSWER=all storage space is allocated to a single
partition, often used for the operating system, applications, and user data.
First Come, First Served - CORRECT ANSWER=CPU-scheduling algorithm that processes
tasks in the order they arrive, similar to a queue
(Disk scheduling)
Round Robin - CORRECT ANSWER=a CPU scheduling algorithm where each process is
assigned a fixed time slice in a rotating order
Nonpreemptive Scheduling - CORRECT ANSWER=Processes run to completion without
interruption.
Process life cycle stages - CORRECT ANSWER=Hint: 5 total processes
-New: A process initially created and enters the system in this state
-Ready: The process is prepared to execute and is waiting for the cpu to become available
-Running: Process is currently being executed by the CPU
-Waiting: Process is temporarily paused, awaiting an event like input/output or the completion of
a resource request
-Terminated: The process has completed its execution and is being removed from the system.
what does the // mean in pseudocode? - CORRECT ANSWER=Round/ Int
Example of converting integer to a floating point number - CORRECT ANSWER=myFloat
x=a/1.0
Stack sorting - CORRECT ANSWER=Sorting in a "Stack of flashcards" way.
Downside is this requires space for two complete decks (Arrays). Not optimal for storage space.

Bubble Sort - CORRECT ANSWER=Starting with the last array element, we compare pairs of
elements, swapping them whenever the bottom element of the pair is smaller than the one above
it.
The smallest element "Bubbles up" to the top of an array.
Insertion sort - CORRECT ANSWER=builds the final sorted array one item at a time.
EX. Sorting a hand of playing cards- pick up one at a time and insert into correct spot in your
already sorted hand.
Binary Search - CORRECT ANSWER=Items need to be sorted. it either finds the item or
eliminates half the array with one comparison. The algorithm starts searching in the middle of an
array in a binary search.
Sequential/linear search - CORRECT ANSWER=Straigh forward concept. Look at each item in
turn and compare it to the one for which we are searching. if it matches, we have found the item.
If not it continues searching for the item. We either stop when finding the item or we have looked
at all the items and not found a match. The search repeats depending on the conditions in the
expression.
-does not need to be sorted.
Count-controlled loop - CORRECT ANSWER=Repeats a process a specified number of times.
The looping mechanism counts each time the process is repeated and tests whether it has finished
before beginning the process again.
Data Types - CORRECT ANSWER=Define the kind of data a variable can hold: integers, floats,
characters, Booleans.
Variables - CORRECT ANSWER=Named memory locations that store data.
Assignment Operator - CORRECT ANSWER=`=` assigns values.

Camel Casing - CORRECT ANSWER=myVariableName; Snake Casing - my_variable_name.
Control Structures - CORRECT ANSWER=Loops (while, for), conditionals (if, else).
Arithmetic Operators - CORRECT ANSWER=+, -, *, /.
Function/Subprogram - CORRECT ANSWER=Reusable block of code.
Parameters vs Arguments - CORRECT ANSWER=Parameters are placeholders; arguments are
actual values.
Strong Typing - CORRECT ANSWER=Enforces consistent data type usage.
Data Structures - CORRECT ANSWER=Array, Stack, Queue, Linked List, Record.
Algorithm - CORRECT ANSWER=Step-by-step process for solving a task.
Pseudocode - CORRECT ANSWER=High-level outline of code logic.
Sequential Search vs Binary Search - CORRECT ANSWER=Linear vs divided search.
Sorting Algorithms - CORRECT ANSWER=Bubble, Insertion, Selection sort.
Composite Variable - CORRECT ANSWER=Can store multiple values.
Flowchart Symbols - CORRECT ANSWER=Terminal (oval), Process (rectangle), Input/Output
(parallelogram).
