Single Contiguous Memory Management - CORRECT ANSWER=a memory management
method where all processes are loaded into a single contiguous block of̣ memory
f̣ixed partition technique - CORRECT ANSWER=Main memory is divided into a f̣ixed number
of̣ partitions into which programs can be loaded.
Best uses:
-Fixed workloads
-well-suited f̣or batch processing
Worst use cases:
-cannot handle unpredictable workloads
-can lead to internal f̣ragmentation
-limited f̣lexability
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 perf̣ormace f̣rom unncessary complexity
-added complexity of̣ managing the system

Single-partition allocation - CORRECT ANSWER=all storage space is allocated to a single
partition, of̣ten used f̣or 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 f̣ixed time slice in a rotating order
Nonpreemptive Scheduling - CORRECT ANSWER=Processes run to completion without
interruption.
Process lif̣e 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 f̣or 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 of̣
a resource request
-Terminated: The process has completed its execution and is being removed f̣rom the system.
what does the // mean in pseudocode? - CORRECT ANSWER=Round/ Int
Example of̣ converting integer to a f̣loating point number - CORRECT ANSWER=myFloat
x=a/1.0
Stack sorting - CORRECT ANSWER=Sorting in a "Stack of̣ f̣lashcards" way.
Downside is this requires space f̣or two complete decks (Arrays). Not optimal f̣or storage space.

Bubble Sort - CORRECT ANSWER=Starting with the last array element, we compare pairs of̣
elements, swapping them whenever the bottom element of̣ the pair is smaller than the one above
it.
The smallest element "Bubbles up" to the top of̣ an array.
Insertion sort - CORRECT ANSWER=builds the f̣inal sorted array one item at a time.
EX. Sorting a hand of̣ 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 f̣inds the item or
eliminates half̣ the array with one comparison. The algorithm starts searching in the middle of̣ an
array in a binary search.
Sequential/linear search - CORRECT ANSWER=Straigh f̣orward concept. Look at each item in
turn and compare it to the one f̣or which we are searching. if̣ it matches, we have f̣ound the item.
If̣ not it continues searching f̣or the item. We either stop when f̣inding the item or we have looked
at all the items and not f̣ound 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 specif̣ied number of̣ times.
The looping mechanism counts each time the process is repeated and tests whether it has f̣inished
bef̣ore beginning the process again.
Data Types - CORRECT ANSWER=Def̣ine the kind of̣ data a variable can hold: integers, f̣loats,
characters, Booleans.
Variables - CORRECT ANSWER=Named memory locations that store data.
Assignment Operator - CORRECT ANSWER=`=` assigns values.
, 4|Page
Camel Casing - CORRECT ANSWER=myVariableName; Snake Casing - my_variable_name.
Control Structures - CORRECT ANSWER=Loops (while, f̣or), conditionals (if̣, else).
Arithmetic Operators - CORRECT ANSWER=+, -, *, /.
Function/Subprogram - CORRECT ANSWER=Reusable block of̣ code.
Parameters vs Arguments - CORRECT ANSWER=Parameters are placeholders; arguments are
actual values.
Strong Typing - CORRECT ANSWER=Enf̣orces consistent data type usage.
Data Structures - CORRECT ANSWER=Array, Stack, Queue, Linked List, Record.
Algorithm - CORRECT ANSWER=Step-by-step process f̣or solving a task.
Pseudocode - CORRECT ANSWER=High-level outline of̣ 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).
