Wireless Access Point
Router
Residential Gateway and
Gateway

Wireless adapter

18. Modem

19. Repeater
Repeater receives signal from a
transmitter, amplifies it, and
retransmits it to a receiver

20. Bridge
unite different networks

21. Hub
Hub is the central connection point
in a network that uses
star topology

22. Switch
Like hub, switch works as the central connection point
in a network. However when a switch receives a
packet from a sending computer, it examines the
destination address (i.e. MAC address of the
destination computer) from the packet header and
retransmits the packet to the destination computer
only .

23. Access point
Access point in wireless LAN (Wi-Fi)
functions like a hub or a switch in wired
network. It connects computers or
devices together to create a wireless
network

24. Router
Router functions to forward packets across
different networks. Router maintains a routing
table. The routing table contains IP addresses
of other networks routers.

25. Residential Gateway
Residential gateway is basically a router that is
configured to enable the sharing of a single
Internet connection (subscription) by multiple
users in a home network.

26. Gateway
Gateway functions to connect two
completely different networks. It
performs protocol translation.

27. IP Address
• 4 Octets
• 32 bits
• 128 bits

28. IP Address – Two Parts
• Network part
• Host part

30. Network Type Address Range

31. Private IP Address
• 10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
• Loopback address=127.0.0.1

32. Subnet Mask
When setting up subnets the
following must be determined
•Number of segments
•Hosts per segment

33. Calculation

34. Network Operating system
Functions
• File and print sharing.
• Account administration for users.
• Security.

35. Example for NOS
• JUNOS, used in routers and
switches from Juniper Networks.
• Cisco IOS
• Linux
• Microsoft Windows Server
• Novell Netware

36. DHCP
Dynamic Host Configuration
Protocol (DHCP) is a network
protocol that enables a server to
automatically assign an IP
address to a computer from a
defined range of numbers

37. Background:
• DIU’s Vision is to guide to build-up
desire career for every students in
DIU
• To accomplish the goal DIU has
taken series of short & long career
related workshops to bloom their
talents
• We can’t put a student in a career
relevant job, but we can train them
to be better able to find a career
relevant job themselves

38. Continue--• Most employers today ONLY
process applicants via on-line
applications
• This allows them to store, search,
and contact prospective
employees in a much easier way
then through hard copy
applications
• But the employers have indicated
that many area applicants are not
comfortable applying on-line; they
don’t have basic computer skills

39. Continue -------So our ending session is focusing
on
-
Defining Career path
Getting Career Advices
Creating web email address
Performing on-line application
Finding desire career relevant
jobs
Example: Google
(effective use to increase productivity)
