1. address binding - ANSWER the process of mapping a program's symbolic
addresses to physical addresses in memory
2. application software - ANSWER programs designed to help users perform
specific tasks, such as word processing, web browsing, or gaming
3. batch processing - ANSWER a method of executing a series of jobs on a
computer without manual intervention where tasks are processed in batches
4. base register - ANSWER a register in the CPU that holds the starting address
of the current memory segment; used in address translation
5. bounds register - ANSWER a register that holds the ending address of a
memory segment, ensuring that memory accesses stay within the allocated
range
6. context switch - ANSWER the process of storing and restoring the state of a
CPU so multiple processes can share a single CPU
,7. CPU scheduling - ANSWER the method by which an operating system
decides which processes should be executed by the CPU and in what order
8. demand paging - ANSWER a memory management scheme where pages of
data are brought into memory only when they are needed rather than in
advance
9. dumb terminal - ANSWER a simple display and input device with no
processing power relying on a central computer for computing tasks
10.dynamic partition technique - ANSWER a memory management method
where memory is divided into variable-sized partitions based on the needs of
processes
11.first-come, first-served (FCFS) - ANSWER a CPU scheduling algorithm that
processes requests in the order they arrive without priority
12.fixed partition technique - ANSWER a memory management method where
memory is divided into fixed-sized partitions, each holding one process
13.Declarative Paradigm - ANSWER A paradigm or model where results are
described but the steps are not explicitly stated.
14.Functional Model - ANSWER A subset of the declarative paradigm that is
based on the concept of the mathematical function, where the solution is
express in terms of a function call.
,15.Logic Programming - ANSWER A subset of the declarative program that is
based on principles of symbolic logic, where we ask questions about objects
and their relationships.
16.Imperative Paradigm - ANSWER A model in which code is executed in
sequential order. It also describes the von Neuman model or sequential
instructions.
17.Procedural Paradigm - ANSWER An imperative model where statements are
grouped into sub programs, an hierarchy of sub programs.
18.Strong typing - ANSWER A requirement where a variable can only have a
value of the proper data type.
19.Encapsulation - ANSWER The bundling of data and actions to form an
object where that object can only about itself.
20.Classes - ANSWER A method or a language construct that provides the
mechanism for encapsulating properties and actions for an object class.
21.Inheritance - ANSWER The ability for classes to inherit data and methods
from other classes.
22.Superclass - ANSWER A class in which another class inherits from.
23.Derived class - ANSWER The class doing the inheriting from the
superclass.
, 24.Polymorphism - ANSWER A ability of a program to handle ambiguity,
where a two different classes may have the same method name.
25.analog data - ANSWER data represented in a continuous and variable form
26.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
27.bandwidth - ANSWER the maximum rate of data transfer across a network
or communication channel, usually measured in bits per second
28.binary - ANSWER a numerical system that uses only two digits, zero and
one, to represent data in computing
29.Boolean expression - ANSWER a logical statement that can only be true or
false and uses operators like AND, OR, and NOT
30.character - ANSWER a single letter, digit, or symbol used in writing text
31.character set - ANSWER a collection of characters that a computer can
recognize and process, like ASCII or Unicode
32.compression ratio - ANSWER the ratio of the original data size to the
compressed data size, indicating how much the data has been reduced
33.control structure - ANSWER constructs in programming that control the
flow of execution, such as loops and conditional statements
