This document provides information on various Windows tools for system information, security, restore points, character input, disk defragmentation, and network hardware components. It discusses the System Information tool for viewing computer details, Security Center for checking security essentials, System Restore for reverting system files to earlier points, Character Map for inserting symbols, and Disk Defragmenter for consolidating fragmented files. It also outlines common network hardware like network interface cards, cables, repeaters and hubs, and routers. The document provides instructions for configuring network settings like computer name, workgroup, and IP address in Windows. It explains the ping and ipconfig commands used to verify network connectivity and settings. Finally, it addresses two security problems

8. COMPUTER NETWORK:
Components of network
hardware
All networks are made up of basic hardware building blocks to
interconnect network nodes, such as Network Interface Cards
(NICs), Repeaters, Hubs, cables and Routers.

9. Network Card
A network card, network adapter
or NIC,
is a piece of computer hardware
designed to allow computers to
communicate over a computer
network.
It allows users to connect to
each other by using cables or
wireless.

10. Cables & connectors
 Twisted pair using
a RJ45 connector
 Coaxial cable
 Optical cables

11. Repeaters and Hubs
A repeater is an electronic device
that receives a network signal,
cleans it of unnecessary noise, and
regenerates it. The signal
is retransmitted at a higher power
level, so that the signal can cover
longer distances without
degradation
A repeater with multiple ports is
known as a hub. .

CONNECTIONS

14. Network software
settings and protocols
 Name and workgroup
Clicking on “my
PC” with the

the mouse,
access to
properties.

15. If we click in computer
name tab, we can find the

the last box of IP adrees

17. MSDOS COMMANDS
 Ping
It is a utility used to verify if a network data packet is capable of being distributed
to an address without errors.
Allows you to ping anothercomputerwhere the x's are locatedare where
you would place the IP address of the computeryou are attemptingto ping

18. If this is not able to complete, this should relay back an
unsuccessful message.
If we write “ping” and a wrong IP adress, this box would appear with
a "timed out" error instead of a reply. It means there is a breakdown
somewhere between your computerand the domain

Genuine Advantage" to buy the WindowsOriginal as

not remember having bought. Let me know how I
can delete the notice and how I can prevent myself
from getting it again.
SECURITY PROBLEMS
Problem 1:

21. Answer:
Windows GenuineAdvantage notifications occur when your computerhasn't passed
the validation test.
The validation test can be failed because you installed a pirated non-genuinecopy of
XP, or because you have changed your XP productkey to a software-generated key,
or sometimes it just happensfor no reason at all.
If you are being constantlynagged by Microsoft to validate your Windows license,
you have the option of purchasing a genuine copy of Windows XP or resolving the
problemlater. However, there is actuallya way of disabling the message by editing
your registry.
So, if you want to remove thoseannoying notifications, you can follow one of these
5 methods that you can find in this website:
