LAB 1 – OPERATING SYSTEM NETWORK UTILITIES ON A WINDOWS PC
Objectives:
In this workshop you will:
Explore operating system utilities that monitor your PC and the network connected to your PC
1. Manage PC network connection
Equipment:
1. Windows Computer
Introduction:
All operating systems include software libraries that allow programming languages access to the network
connections. Some examples include .NET development framework in Windows, Windows Control Panel
applets (CPL), Unix sockets and command prompt executable utilities and code (for example CMD,
PowerShell, Unix sh). The Windows and Unix command prompt can be used to configure, monitor and
repair network components. Network professionals must understand the operating system view of the
network and how to adjust network parameters to match the equipment in Telecommunication rooms and
Equipment rooms as well as wireless connections to remote access points
LAB Part A: Resource Monitor utility
Please work individually.
Windows operating system (and also other operating systems) support utilities that monitor and display real
time information about PC and its resource (e.g. RAM, CPU, Disk I/O and Network I/O), utilization.
Procedure:
1. In Windows 10 search option, search for Resource Monitor. Choose Resource Monitor App.
2. While looking at different parts of “learn.humber.ca” observe the values on Network plane,
“Processes with Network Activity”. Fill in the following information:
a. Bytes Sent (Transmitted Bytes): 2
b.
Received Bytes: 52629
1
3. Switch to the CPU Utilization pane. Fill in the following information:
a.
b.
Total Processes CPU Usage (%) 3%
What is the CPU Usage for your browser’s PID (%) 3.67
2
LAB Part B: Connectivity to host and site test
All operating systems provide utilities to test connectivity to different servers or hosts. Following are the two
common utilities: ping and tracert
Procedure:
1. Run (the keyboard shortcut is <Windows> R) the Command Prompt (cmd).
2. Type ping humber.ca
3. Fill in the following questions:
a. IP address of the destination (ping humber.ca)  192.75.71.50
b. Average reply time of the four requests  17
ms
c. What does TTL stand for 
d.
time to live
What units of measure does TTL use  Seconds
4.
Type the command: tracert humber.ca (Hint: to stop tracert, use <ctrl> C). Tracetr shows
the gateway IP address through which the request leaves your computer (it is given as first hop when
tracert command is executed), followed by all the IP routers your request passes through.
a. How many hops did it take to reach humber.ca 10
b.
c.
hops
Gateway IP address from your computer: 10.0.0.1
IP Address of the Last Hop: 192.75.71.50
3
LAB Part C: Network Interface information and details
IPCONFIG command lists information about all Internet Protocol interfaces configured on your computer.
Procedure: Run ipconfig command. Focus on the interface that has an active connection (eg. Does not list
“Media disconnected”).
1. Fill in the following information from ipconfig
10.0.0.52
Subnet Mas 255.255.255.0
Default Gateway IPv4 address 10.0.0.1
a. Your Device’s IPv4 address
b.
c.
4
2. For the same interface as above, run the ipconfig /all command
3. Fill in the information from ipconfig /all
a. Lease Obtained January
b.
c.
d.
15 2022 7:28:58 Am
Lease Expires  January 22 2022 7:28:58 Am
DHCP Server  10.0.0.1
Calculate how long is the lease valid for: 1 week ( 7 days)
LAB Part D: Address Resolution Protocol
Address Resolution Protocol (ARP) is one of the key protocols used in Local Area Networks to determine
the Physical address (MAC address) of the next hop device. In local area network the data frame is sent
based on MAC address of a device that is capable of connecting to the internet. The internet device is
known as the Gateway or the next hop. ARP finds physical address of the next device from where the
frame leaves the local area network to the internet. You may use the help command (arp /?) to list the
functions that the ARP command can perform.
Procedure:
1. Run the command arp -a command
2. Fill in the following information
a. your gateway IP address
b. physical address (MAC address) of your gateway  08-a7c0-98-e3-0b
c. your IP Interface address based on arp –a 10.0.0.52
d. what is the function of the command
arp –d *
to delete an entry from arp
table

Additional learning opportunity:
Network Statistics Utility (netstat utility):
When your computer connects to network or internet, number of bytes (e.g. request to connect) are sent out
and the reply (e.g. web page information) comes back and is displayed on your browser. One of the network
utility, netstat keeps the statistics on your network activity. Try the following:
At the Command prompt (cmd):
•
•
•
•
Type the netstat -e command.
Note the number of Bytes sent and received
Wait 60 seconds
Type the netstat -e command again.
Calculate how many Bytes were SENT and RECEIVED by your computer in 60 seconds. Take difference of
the two values (Bytes SENT and RECEIVED) in the two displays.
6
Run the utility netstat -r
This utility is used to lists 2 parts of your computer’s communication state.
•
•
The Interface List shows the 6 Byte address of your LAN controller and a textual description of each
interface.
The Route Table shows active Network Routes. The key Network addresses are the Destination,
Gateway and Interface.
Note the LAN address of your commuter’s interface, the description (or name) of your LAN address, the
gateway address and the IP interface address.
