5 What OSI Model Layer labels data performs segmentation? A.Application, Presentation, or Session B.Transport C.Network D.Data Link E.Physical 3 of 7

6 Which protocol will deliver a large data file the most rapidly? A.FTP B.HTTP C.TCP D.UDP E.HTTPS 4 of 7

7 Which item is not found in the TCP header? A.ACK number B.Source IP Address C.Source Port Number D.Window Size E.Checksum 5 of 7

8 A client requests a Web page. What TCP port on the Web server receives the request? A.23 B.53 C.80 D.110 E.A port larger than of 7

9 A client requests a Web page. What TCP port on the client sends the request? A.23 B.53 C.80 D.110 E.A port larger than of 7

10 After 4.2

11 When a user opens a Web page, what is the first TCP packet sent to the server? A.SYN B.SYN/ACK C.HTTP GET D.ACK E.ARP 1 of 5

15 What TCP Header Field has the value 80 in an HTTP GET segment? A.Source Port B.Checksum C.Flags D.Sequence Number E.Destination Port 5 of 5

16 Binary Lesson 4 Hexadecimal and Binary Practice

17 Counting to 15 Base Base Base 16 Base Base Base 16 Two Ten (Hex) Two Ten (Hex) A A B B C C D D E E F F

18 Four Bits Make a Nybble A nybble can be represented by one hexadecimal digit Values from 0 to 15, or 0 to F 8s 4s2s1s

19 Eight Bits Make a Byte So this number is = 153 8s4s2s1s8s4s2s8s4s1s2s8s4s 16s32s 128s 64s16s32s64s16s32s One nybble: 0 through F One nybble: 0 through F

20 Two hexadecimal digits make a byte So this number is $99 = 9* = = 153 One nybble: 0 through F # of 16s One nybble: 0 through F # of 1s

21 Binary iClicker Questions

23 What is $A0 in decimal? A.160 B.100 C.10 D.255 E.90 2 of 11

24 What is 64 in hexadecimal? A.$20 B.$30 C.$34 D.$40 E.$44 3 of 11

25 What is 252 in hexadecimal? A.$F0 B.$F8 C.$FA D.$FC E.$FE 4 of 11

26 Convert this binary number to hexadecimal: A.$23 B.$63 C.$67 D.$69 E.$6B 5 of 11

27 What is the highlighted IP Address? A B C D E.Something else 6 of 11

28 Convert this IP address to hexadecimal: A B C D.7F E.7D of 11
