NETWORKING QUIZ 3

Application Layer

The layer of the TCP/IP model handles many upper-level functions including data generation, translations, conversions, compression and encryption.

Clients (Workstations)

Network components which are computers that access and use the network and shared network resources.

Hub

Network components device that splits a network connection into multiple computers.

Internet Layer

The layer in the TCP/IP that functions mainly about IP addressing and routing.

Packet Switching

The method for sending data from one device to another across the internet.

Network Access Layer (Link Layer)

The layer in the TCP/IP that has the main functions are frame making, MAC addressing, frame switching and physical cabling.

Operating System

Network components like Unix, Linux, Windows 2000, Windows 98, Windows XP, allows personal computers to access files, print

Network

Share common devices, functions, and features including servers, clients, transmission media,

Network Interface Card (NIC)

Network components special expansion card that handles Mac address.

Network Operating System (NOS)

Network components like Windows Server, is a program that runs on computers and servers that allows the computers to communicate over the network.

OSI Model

A logical and conceptual model that defines network communication used by systems open to interconnection and communication with other systems.

Router

Network components device that used to connect a LAN with an internet connection.

FALSE

• TCP and IP are not separate protocols

• TCP obtains and defines the address

• The link layer combines both network and physical layer

• Application layer = Application + Presentation + Transport

• The OSI model has 7 layers, not 4.

TRUE

• IP is responsible for transporting and routing data.

• TCP is responsible for defining how applications/devices exchange packets.

• Every device has an IP address that uniquely identifies it.

• TCP organizes data for transmission between server and client.

• The transport layer of TCP/IP = transport layer of OSI.

• every device has an IP address that uniquely identifies it.

• TCP guarantees integrity of communicated

Servers

Network components which are computers that hold shared files, programs, and the network operating system.

Shared Resources

Data that file servers provide to clients such as data files, printer access programs and e-mail.

Network Services

Network components hardware resources provided to the users of the network by servers.

Modem

Network components, a telecommunication device grouped as one of computer network components.

TCP (Transmission Control Protocol)

It is designed to send packets across the internet and ensure the successful delivery of data and messages over networks.

IP (Internet Protocol)

The default method of data communication on the Internet.

Transmission Media

The facilities used to interconnect computers in a network, such as twisted-pair wire, coaxial cable, and optical fiber cable.

Transport Layer

The layer in the TCP/IP that has the main functions include data segmentation, flow control and error checking.

Clients

Network components are basically the customers (users) of the network, as they request and receive services from the servers.

Network components

The customers (users) of the network, as they request and receive services from the servers.

IP address

A unique identifier assigned to every device on a network.

NIC (Network Interface Card)

Network components that prepare (formats) and sends data, receives data, and controls data flow between the computer and the network.

OSI Model

has 7 layers

Router

This network component is used when you have two distinct networks (LANs) or want to share a single internet connection to multiple computers.

Server

Network components that provide access to network resources to all the users of the network.

Resources

Network components that are resources provided include data files, printers, software, or any other items used by clients on the network.

Switch

Network components that use physical device addresses in each incoming message to deliver the message to the right destination or port.

API (Application Programming Interface)

A communications standard that enables application programs and computing devices to exchange messages over a network.

Protocol

Defines how devices should transmit data between them and enables communication over networks and large distances.

OSI Model

Identify the characteristics: The model helps standardize router, switch, motherboard, and other hardware.

TCP/IP Model

The model that has 4 layers and helps determine how a specific computer should be connected to the internet and how data can be transmitted.

OSI Model

Identify the characteristics: The model that helps establish a connection between different types of computers.

5G

A faster mobile network allowing quicker downloads, smoother video calls, and better performance for smart devices.

Wi-Fi 6

A new version of Wi-Fi with faster/more stable internet in crowded areas.

Cloud Computing

Using the internet to manage, store, and access network resources.

Software-Defined Networking (SDN)

A smarter way to control networks using software.

Self-Healing Networks

Networks that adjust automatically using scripts or AI.

AI-Driven Networking

Helps detect problems, improve security, and manage traffic.

Enhanced Network Security

Stronger protection from hackers, viruses, and data theft.

Edge Computing

Processing data closer to where it's needed.

Green Networking

Energy-efficient hardware and designs to reduce power use.

Network Administrator

Manages and maintains networks.

Network Engineer

Designs and builds networks.

Network Technician

Installs, repairs, and troubleshoots hardware.

System Administrator

Takes care of servers and network systems daily.

Cybersecurity Specialist

Protects networks from hackers and threats.

Cloud Engineer

Works with AWS/Azure to manage cloud networks and services.
