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')

  True

  False

 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.

  True

  False

 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

  communication protocol

  transportation rule

  port forwarding protocol

  None of the above

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

  Transmission Central Port / Internet Protocol

  None of the above

  Transmission Control Protocol / Internet Protocol.

  Transport CPU Protocol / Important 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.

  None of the above

  both follow completely different protocols and rules and are distinct

 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.

  four separate protocol firewalls

  four connected layers

  None of the above

  four security warnings

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

  Application, Transportation, Netherlinking and Letodomain

  DNS, ISP, IP and Domain

  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 – 
_______________________________
________________________________

  Transport Protocol and Link Layer Protocol

  None of the above

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

  Application and Network protocol

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

  TRUE

  FALSE

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

  DNS server

  Domain name

  MC address

  IP address

 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.

  network port

  fqdn layer

  domain name server (DNS)

  protocol built in to the computer

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

  managed request

  None of the above

  network request

  communication request

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

  "binary sequence transfer"

  "handshake"

  "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

  simple duplex

  double duplex

  half duplex

  full 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)

  private virtual network

  main home network

  virtual private network (VPN)

  internet

 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.

  TRUE

  FALSE

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

  All of these options are valid answers

  packetized and addressed

  transmitted and routed

  received

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

  FALSE

  TRUE

 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

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

  the network routers and wireless acess points (WIFI)

  delivering packets to network devices

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

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

  FALSE

  TRUE
