analog data - answer ; data represented in a continuous and variable form
American Standard Code for Information Interchange (ASCII) - answer ; a standard encoding system for
text characters that uses numeric values to represent letters, numbers, and symbols
paged memory technique - answer ; a memory management method that divides memory into fixed-
size pages to minimize fragmentation and efficiently manage memory
partition memory management - answer ; a method of dividing memory into segments or partitions,
each of which can hold a different process
physical address - answer ; the actual location in computer memory hardware where data is stored
preemptive scheduling - answer ; a CPU scheduling method where a running process can be interrupted
and replaced by another process before it finishes
process - answer ; an instance of a running program, including its current state and memory information
process control block (PCB) - answer ; a data structure the operating system uses to store all
information about a process
,process management - answer ; managing the operating system's execution of processes, including their
creation, scheduling, and termination
process states - answer ; the various stages a process goes through during its lifecycle, such as new,
ready, running, waiting, and terminated
real-time system - answer ; a computing system that processes data and responds to inputs in a specific,
often very short, time frame
response time - answer ; the time taken from the submission of a request to the start of the system's
response
round-robin - answer ; a CPU scheduling algorithm where each process is assigned a fixed time slice in a
rotating order
shortest job next (SJN) - answer ; a CPU scheduling algorithm that selects the process with the shortest
expected execution time next
single contiguous memory management - answer ; a memory management method where all processes
are loaded into a single contiguous block of memory
system software - answer ; software designed to provide a platform for other software, including
operating systems and utility programs
thrashing - answer ; a condition where excessive paging operations occur leading to reduced system
performance
time slice - answer ; a fixed amount of CPU time allocated to each process in a round-robin scheduling
algorithm
timesharing - answer ; a method where multiple users can access a computer system concurrently by
sharing time slices of the CPU
,turnaround time - answer ; the total time taken from the submission of a process to its completion
virtual machine - answer ; software emulation of a physical computer, providing the same functionality
as a physical machine
virtual memory - answer ; a memory management technique that creates an illusion of a large
contiguous memory space by using disk storage to extend physical memory
Memory management - answer ; Allocating and managing system memory to optimize performance and
prevent conflicts.
Process management - answer ; Handles the creation, execution, and termination of processes, ensuring
efficient operation and resource allocation.
CPU scheduling - answer ; Determines the order in which processes are executed by the CPU, optimizing
performance and responsiveness.
absolute path - answer ; The complete and specific location of a file or directory in a file system, starting
from the root directory.
binary file - answer ; A file that contains data in a format that is not human readable; typically used to
store executable programs or complex data structures.
direct file access - answer ; The ability to retrieve or manipulate data from a file directly without
sequentially accessing preceding data.
directory - answer ; A container used to organize files into a hierarchical structure on a computer
system.
directory tree - answer ; A graphical representation or hierarchical structure of directories and
subdirectories in a file system.
, disk scheduling - answer ; The method an operating system uses to efficiently schedule access to disk
resources, aiming to reduce seek time and optimize performance.
file - answer ; A named collection of data stored on a computer system, which can be text, an image, an
executable, or any other type of information.
file extension - answer ; A suffix attached to the end of a filename indicating the format or type of the
file.
file system - answer ; The method and data structure an operating system uses to organize and store
files on storage devices such as hard drives.
file type - answer ; The classification or category of a file based on its content and format that
determines how it can be used or opened.
path - answer ; A string of characters that specifies the location of a file or directory in a file system.
relative path - answer ; A path that specifies the location of a file or directory relative to the current
working directory.
root directory - answer ; The top-level directory in a file system hierarchy, which contains all other
directories and files.
seek time - answer ; The time it takes for a hard drive's read/write head to move to the track where the
data are stored.
sequential file access - answer ; Accessing data in a file by sequentially reading or writing from the
beginning to the end.
text file - answer ; A file that contains plain text characters, typically encoded in ASCII or Unicode, and is
readable by text editors and word processors.
