1 Information technology Data creation Data maintenance Data transfer

2 Computer Network Network advantages

3 Network typs  Topology  Management method  Scale

4 Scale LAN MAN WAN

5 LAN concept LAN specification  High Performance  High security  High speed  Low cost  Easy expansion  Limited

6 MAN Concept WAN Specification  Performance  Security  Speed  Cost  Expansion  limited

7 WAN Concept WAN Specification  Performance  Security  Speed  Cost  Easy Expansion  limited

8 Bandwidth concept The data transfer capacity of a digital communications system as measured in bits per second (bps).

9 Topology Wired topology Wireless topology

10 Wired topology  BUS  STAR  RING  MESH

11 Wire less topology  ad-hoc  Infrastructure

12 BUS

13 Collision Terminator Signal bounce

14 STAR

15 straight & cross cable

16 HUB Passive Active Smart (switch)

17 RING

18 MAU

19 MESH

20 Ad-hoc

21 Infrastructure (access point)

22 OSI open system interaction

23 TCP/IP

24 Application Outlook Yahoo! Messenger Google talk Browser...

25 Transport Operation systems Error detection Flow control power flow Idle OUTCOM : segment

26 Internet INCOME : segment OUTCOM : packet

27 IP 0-255 0-255 0-255 0-255...

28 IP Net ID : common in the Network Host ID : exclusive for computers Subnet : All of them have same Net ID

29 IP Class A 0 – 127 255.0.0.0 Class B 128 – 191 255.255.0.0 Class C 192 – 223 255.255.255.0 Class D 224 – 239 Class E

30 IP Static Dynamic ( DHCP) APIPA

31 Subnet & Router

32 Network Interface LAN Token Ring (Ring 802.5) Ethernet (Star & Bus 802.3 ) Wireless. OUTCOM : FRAM

33 Ethernet Access method Ethernet algorithm is CSMA/CD CS carrier sense MA multiple access CD collision detect Result : CSMA/CD is Demand priority star & bus have Demand priority by HUB

34 IEEE 802 IEEE 802.3 Ethernet IEEE 802.5 Token Ring IEEE 802.11 wireless IEEE 802.16 WiMAX

35 Network Interface WAN ATM DSL Frame Relay ISDN Dial-up Loadsed lined soNet CATV.

36 Network Device Cable TP Stp Utp Ftp UTP : CAT1,CAT2,CAT3,CAT4, CAT5,CAT6,CAT7

37 Cable - coaxial
