Lesson 1 - Modes of Connections Flashcards
What is a wired network?
A wired network is a type of network that uses physical cables to connect devices.
What is a wireless network?
A wireless network is a type of network that uses radio waves to connect devices without physical cables.
True or False: Wired networks are generally faster than wireless networks.
True
What protocol is commonly used for wireless networking?
Wi-Fi (IEEE 802.11)
Fill in the blank: The __________ layer is responsible for data transfer between devices in a network.
Transport
What is the primary function of the network layer in the OSI model?
To route data packets between different networks.
Which layer of the OSI model handles error detection and correction?
Data Link layer
What is the main difference between TCP and UDP?
TCP is connection-oriented and reliable; UDP is connectionless and does not guarantee delivery.
True or False: The physical layer of the OSI model deals with the transmission of raw bitstreams over a physical medium.
True
What does the acronym LAN stand for?
Local Area Network
What is the purpose of protocols in networking?
Protocols define rules and conventions for communication between network devices.
Which protocol is used for sending emails?
SMTP (Simple Mail Transfer Protocol)
Fill in the blank: The __________ layer provides services for data encryption and security.
Application
What type of network uses both wired and wireless connections?
Hybrid network
What is the role of the Internet Protocol (IP)?
To route packets across network boundaries.
What are the two primary modes of connections in computer networking?
Connection-oriented and connectionless.
True or False: Connection-oriented communication guarantees the delivery of data packets.
True.
Fill in the blank: In a connectionless mode, data is sent without establishing a ________.
connection.
Which protocol is commonly associated with connection-oriented communication?
TCP (Transmission Control Protocol).
What is a key characteristic of connectionless communication?
Data packets are sent independently without prior setup.
