FINAL EXAM Question and Answers [100%
Correct] 2025
What is the purpose of the binary system in computer communication?
The binary system, also known as the base-2 numeral system, is used by computers to represent
data using only two states: 0 and 1. This forms the basis of all computer operations, allowing for efficient
data processing and communication.
Explain what a byte is and why it is significant in computer systems.
A byte is a group of 8 bits that can store a single character of data. This grouping allows for 256
different values (2^8), which makes it fundamental for representing characters, numbers, and other data
forms in computers.
What is character encoding, and why is it necessary?
Character encoding assigns binary values to characters, translating data into a format that is
human-readable. This ensures that binary data can be accurately represented as text or symbols across
different systems and applications.
How does UTF-8 encoding differ from simpler encoding systems like ASCII?
UTF-8 allows characters to be stored using one to four bytes, enabling the representation of a
broader range of characters and symbols, including those from various languages and special symbols,
compared to ASCII, which is limited to 128 unique characters using one byte per character.
What are logic gates, and what role do they play in computing?
Logic gates are electronic components that perform logical operations using binary input signals
to produce an output. They enable transistors to perform complex tasks, such as making decisions about
electrical signal paths based on given conditions.
What is the highest decimal number you can represent using one byte?
1
, The highest decimal value that can be represented with one byte is 255, as it covers values from 0
to 255.
How does abstraction help simplify computer systems for users?
Abstraction involves simplifying a complex system by reducing its details to more manageable and
comprehensible elements. This makes it easier for users to interact with and understand computers
without needing to know intricate details of their operation.
What constitutes the hardware layer of a computer?
The hardware layer consists of all the physical components of a computer, such as the CPU, RAM,
hard drives, and input/output devices like keyboards and monitors.
Describe the primary function of an operating system.
An operating system serves as an intermediary between the hardware and the system's software,
facilitating communication, managing resources, and providing a user-friendly interface for applications
to run.
What is the role of the software layer in computing?
The software layer encompasses the applications and programs that enable human interaction
with the computer. It serves as the interface between the hardware's operations and the user's input
and output needs.
Who or what is considered the "user" in computing terms?
The user refers to any person or entity that interacts with a computer, typically issuing commands,
inputting data, or using software applications to perform tasks.
What are ports in computer hardware, and why are they important?
Ports are connection interfaces on a computer that allow external devices, such as USB drives,
monitors, or printers, to connect to and interact with the system, thereby extending its functionality.
What is the function of the CPU in a computer system?
