SOHO Network Administration –
Definition
SOHO Network generally use a
small Ethernet Network switch or
hub and cat 5 cabling, or a WIFI
wireless network.
(a) Network Interface Card (NIC) is needed in adding an
additional computer to the LAN using Ethernet.
NIC connects the device’s circuitry to the cable. The NIC
works with programs in each devise to implement the
protocols necessary for communication.
(b) The advantages of using Dynamic Host
Configuration Protocol (DHCP) for the new computer is
when you plug your computer into a LAN (or sign on to a
wireless LAN), a program in Windows or other operating
system will search that network for a DHCP server.
When the program finds such device, your computer will
request a temporary IP address from the DHCP server.
The IP address is loaned to you while you are connected
to the LAN.
When you disconnect, that IP address becomes
available, and the DHCP server will reuse it when
needed.
(c) The line between the base station and the modem is not
a telephone line. The DSL modem to ISP will be the
telephone line.
(d) The computers, printers, switches and other devices on a
LAN are connected using one or more media. Most
connections are made using Unshielded Twisted Pair
(UTP) cable.
(e) The hardware that is needed to add another wireless
computer is Bluetooth. Bluetooth is another common
wireless protocol. It is designed for transmitting data over
short distances, replacing cables.
(f) The computer user in office 2 must enter office 1 to access
the printer. What must be done to move the printer to a
neutral location between the two offices?
The printer needs to use wireless NIC.
(g) By going to http://cnet.com or another site that lists
computer hardware, the approximate cost of a wireless
printer is $134.99.
It is better to buy a wireless printer server when the
distance between office 1 & 2 are in the range with
the wireless printer.
However it is better to buy a second printer for office
2 instead of a printer server when the distance
between office 1 & 2 is out of the range.
(h) A new computer can be added to the LAN by adding
another Ethernet switch. Both the new Ethernet and
current Ethernet switches can be connected together to
the main switch using optical fibre cables.
(i) All of the computers in this LAN run Microsoft Windows. A
user at computer 1 clicked the LAN icon at the bottom of
his screen and the screen shown in Figure 6A-11 (pg.
250) appeared:
(1) Are the IP addresses in the screen internal or public IP
addresses?
They are internal IP address and public IP address.
(2) What computer is located at IP address 192.168.2.19?
Computer: BDELL
(3) What device is located at IP address 192.168.2.1?
DSL Modem.
The user did not know what device was located at IP
address 192.168.2.28, so he opened his browser and typed:
http://192.168.2.28. The screen shown in Figure 6A-12 (pg.
250) appeared.
(a) Which device on the SOHO LAN has been assigned this
IP address?
Printer
(b) Which device created this display?
Ethernet Switch.
(c) What is the purpose of this display?
To display server status.
Out of curiosity, the user then entered http://192.168.2.1 into
his browser. The display shown in Figure 6A-13 (pg.251)
resulted.
(a) Which device produced this display?
Ethernet Switch
(b) What does “DHCP server enabled” mean?
Assigned IP addresses automatically to a computer.
(c) Explain the entries in the DHCP section.
The DHCP section lists the computers and other
devices that the base station detects on your
network.
(d) The base station has two MAC addresses. What two
devices inside the base station do you think they refer
to?
Printer and Computer
(e) What is the MAC address of the printer server? (use data
from the last two displays)
0x00c002a5e78a
(f) The network administrator for this SOHO LAN can access
a management utility within the base station. She did so
and navigated to the display shown in Figure 6A-14.\
(1) Do the data in this display pertain to the Ethernet switch
or the router?
It displayed router.
(2) This appendix showed the use of DHCP within a LAN.
This screen allows the base station to use DHCP to
obtain its own public IP address from the IP. What
benefits does the ISP accrue by using DHCP?
By using DHCP, the ISP will experience less burden
in supplying the legitimate Internet address.
(3) When would the network administrator not use DHCP
to connect to the ISP?
The network administrator will not use DHCP to
connect to the ISP when:
Internet connection type is static - uses a fixed IP
address provided by your ISP.
Internet connection type is PPPoE – uses point-topoint Protocol over Ethernet.
Internet connection type is Disabled – do not
connect the base station to the internet.
(4) Under what circumstances would someone use a
base station and not connect it to the Internet?
When someone wants to operate the computers
connected at a single physical site, he will only
use a base station and not connect it to the
internet.
