Data link ,Network , and transport
presentation , session , and transport
Application , Transport ,and internet
What is the Protocol Data Unit (PDU) at the Network Layer (Layer 3) of the OSI model called?
Frame
Packet
Segment
Bits
Which Transport Layer protocol is most suitable for an application like live video streaming, where speed is prioritized over the guaranteed delivery of every piece of data?
UDP(User datagram protocol)
ip(Internet Protocol)
Tcp (Transmission Control Protocol)
HTTP(Hypertext Transfer protocol)
Which type of address is used by the Data Link Layer to identify the next immediate device in the data's journey, such as from a computer to its local router?
Port number
Mac address
IP Address
Logical Address
Which of the following tasks is a primary responsibility of the Presentation Layer (Layer 6)?
Providing an interface for the end-user
Dividing Data into segments for transport
Data encryption and compression
Establishing and terminating connections
During the encapsulation process, the Packet received from the Network Layer is wrapped by the Data Link Layer to create what?
Bits , by encoding the packet's Data
A Segment with a Frame header
A Frame , by adding a header and a trailer
A new Packet with an added MAC Address
What is the primary function of port numbers , which are specified in the Transport layer header ?
To ensure that data segments are received in the correct order
To provide a unique hardware identifier for the network interface card
To identify the specific application or service on a device that should handle the data
to determine the best physical path for the data to travel across the internet
At which layer of the OSI model does the DNS (Domain Name System) protocol operate to translate human-readable names like 'google.com' into IP addresses?
Network Layer
Application layer
Session Layer
Transport Layer
What is the key feature of the Transmission Control Protocol (TCP) that distinguishes it as a 'reliable' protocol?
it establishes a connection with a three-way handshake and uses acknowledgements
it sends data as fast as possible without waiting for confirmation
it automatically encrypts all data to source the transmission
it uses MAC addresses to ensure delivery to the correct local device
A network switch primarily operates at Layer 2 of the OSI model . Based on this , what information does it use to make it's forwarding decision ?
The type of the physical medium (copper or fiber)
Destination IP address
Destination MAC Address
Destination Port Number
