01 - Introduction to TCP/IP

 1. The TCP and IP protocols are both in the same layer in the four layer model (i.e the 'Application layer')



 2. Robert Elliot Kahn along with Vint Cerf, invented the Transmission Control Protocol (TCP) and the Internet Protocol (IP), the fundamental communication protocols at the heart of the Internet.



 3. TCP/IP is the _____________________________ for communication between computers on the Internet
TCP/IP is a set of protocols, and is the primary tech of the internet. 
When you browse the web, send email, chat online, online gaming, 
TCP/IP is working busily underneath

  None of the above

  transportation rule

  communication protocol

  port forwarding protocol

 4. TCP/IP stands for:
Note: a protocol is just a set of rules (that defines how something works)

  Transport CPU Protocol / Important Protocol

  Transmission Control Protocol / Internet Protocol.

  None of the above

  Transmission Central Port / Internet Protocol

 5. When two computers exachange data, they can understand each other if __________________

  both are independent of each other and not related at all.

   both follow specific format and rules in a protocol.

  both follow completely different protocols and rules and are distinct

  None of the above

 6. TCP/IP can also be defined as a set of networking protocols that work together as __________________passing incoming and outgoing data packets up and down the layers during network communication.
Note: (hint) The TCP/IP protocol suite uses a 4 layer model.

  None of the above

  four separate protocol firewalls

  four connected layers

  four security warnings

 7. The four layers that are referenced when using TCP/IP are: ________________________________

  DNS, ISP, IP and Domain

  Application, Transportation, Netherlinking and Letodomain

  And, Tor, Nor, and Lor

  Application, Transport, Network and Link

 8. The TCP/IP protocol suite consists of many protocols that operate at one of 4 layers. Fill in the blanks.
The protocol suite is named after two of 
the most common protocols – 

  Application and Network protocol

  None of the above

  TCP (transmission Control Protocol) and IP (internet Protocol).

  Transport Protocol and Link Layer Protocol

 9. TCP/IP defines how electronic devices (like computers) should be connected to the Internet, and how data should be transmitted between them.



 10. On a TCP/IP network every device must have ____________The _______________ identifies the device e.g. computer.

  MC address

  Domain name

  IP address

  DNS server

 11. Just as the IP address identifies the computer, The________________ identifies the application or service running on the computer.
The use of ports allow computers/devices to run multiple services/applications.

  fqdn layer

  protocol built in to the computer

  network port

  domain name server (DNS)

 12. If one application wants to communicate with another via TCP, it sends a ___________________

  network request

  communication request

  None of the above

  managed request

 13. After a _________________ between two applications, TCP will set up a "full-duplex" communication between the two applications.

  "binary sequence transfer"

  "network transfer"

  "router update"


 14. The ______________ communication will occupy the communication line between the two computers until it is closed by one of the two applications.
In a ________ system, both parties can communicate with 
each other simultaneously. 
An example of a ___________ device is a telephone; 
the parties at both ends of a call can speak and be 
heard by the other party simultaneously

  double duplex

  full duplex

  half duplex

  simple duplex

 15. Read the following excerpt about TCP/IP and fill in the blanks
The Internet protocol suite is the conceptual model and set 
of communications protocols used on the ________ and similar 
computer networks. It is commonly known as TCP/IP 
because the foundational protocols in the suite are the
Transmission Control Protocol (TCP) and the 
Internet Protocol (IP)

  virtual private network (VPN)

  main home network

  private virtual network


 16. TCP/IP is occasionally known as the Department of Defense (DoD) model because the development of the networking method was funded by the United States Department of Defense through DARPA.



 17. The Internet protocol suite provides end-to-end data communication specifying how data should be __________

  transmitted and routed


  packetized and addressed

  All of these options are valid answers

 18. TCP/IP, on which the Internet is built, is a single protocol (not a suite of protocols as is commonly thought)



 19. Read the following excerpt about the IP in TCP/IP and fill in the blanks.
IP, which stands for Internet Protocol,is a Network layer 
protocol that is responsible for _______________________
____________________. The IP protocol uses logical IP 
addresses to refer to individual devices rather than 
physical (MAC) addresses

  delivering packets to network devices

  the installation of cables and hardware that is associated with the internet

  the network routers and wireless acess points (WIFI)

  finding the best route that a cable must take (installation)

 20. A protocol called ARP (for Address Resolution Protocol) handles the task of converting IP addresses to MAC addresses
