b) False
Explanation: PS2 and DVI are examples of physical ports. Physical ports can be touched and seen with our naked eyes.
3. Physical ports are usually referred to as ___________
a) jacks
b) cables
c) interfaces
d) hardware plugs
Explanation: Physical ports are connections that connect two systems for their interactions. LAN, PS2 and DVI are examples of physical ports.
4. ____________ are logical numbers assigned for logical connections.
a) Logical ports
b) Physical ports
c) Networking cables
d) IP address
Explanation: Logical ports are end-point to a logical connection. The numbers are pre-assigned by IANA (Internet Assigned Numbers Authority) which ranges from 0 – 65536.
5. Number of logical ports ranges from _____ to _____
a) 0, 255
b) 1, 65535
c) 1, 65536
d) 0, 65536
Explanation: The numbers are pre-assigned by IANA (Internet Assigned Numbers Authority) which ranges from 0 – 65536. All the used protocols are assigned with a unique port number.
6. Logical ports are also known as ________________
a) numbered ports
b) virtual numbering
c) virtual ports
d) network protocol ports
Explanation: Logical ports are also known as virtual ports which are part of TCP/IP networking. The numbers of ports are pre-assigned by IANA (Internet Assigned Numbers Authority) which ranges from 0 – 65536.
7. Virtual ports help software in sharing without interference all hardware resources.
a) True
b) False
Explanation: Virtual ports also known as logical ports helps different applications in sharing without the interference of all hardware resources. The network traffic is automatically managed by routers using these ports.
8. ________ needs some control for data flow on each and every logical port.
a) Antivirus
b) Network firewall
c) Intrusion Detection Systems (IDS)
d) Anti-malware
Explanation: For security reason, there is some additional control provided by the network firewall over data traffic going through each logical ports.
9. The logical port is associated with the type of protocol used along with the IP address of the host.
a) True
b) False
Explanation: During a communication, the logical port is ass associated with the type of protocol used along with the IP address of the host. The numbers logical ports are pre-assigned by IANA (Internet Assigned Numbers Authority) which ranges from 0 – 65536.
10. Which of the following is the port number for FTP data?
a) 20
b) 21
c) 22
d) 23
Explanation: Port number 20 is the logical port number for FTP data service. FTP protocol is a standard protocol used for transmitting and receiving files from client to server through a network.
