What is a chip set?
When we speak about busses and system boards, we are also speaking about chip sets. The
chip sets are a bunch of intelligent controller chips, which are on any system board. They are
closely tied to the CPU, in that they control the busses around the CPU.www.laptoonz.com Without the chip sets,
neither RAM or I/O busses could function together with the CPU:

History of the PC
History of the PC
Computers have their roots 300 years back in history. Mathematicians and philosophers like Pascal, Leibnitz, Babbage and
Boole made the foundation with their theoretical works. Only in the second half of this century was electronic science
sufficiently developed, to make practical use of their theories.www.laptoonz.com
The modern PC has roots back to USA in the 1940's. Among the many scientists, I like to remember John von Neumann
(1903-57). He was a mathematician, born in Hungary. We can still use his computer design today. He broke computer
hardware down in five primary parts:
l CPU
l Input
l Output
l Working memory
l Permanent memory
Actually, von Neumann was the first to design a computer with a working memory (what we today call RAM).

Wireless Technology
Wireless LANs are everywhere – at the office, at home, in the hotel, in the coffee shop or at the airport. The
wireless concept that we take for granted now has its roots in the wireless modem of the early 90’s. Early wireless
modems were designed for single peripheral devices that needed a way to allow devices to send and receive
computer data. The modem speeds that we had grown accustomed to were more than adequate for the task.
Industry professionals drawn to this new emerging field are typically from the Information Systems Networking field
with a strong background in the concepts of wired LAN, MAN and WAN or from the Radio Telecommunications field
with an in-depth experience in wireless communication. This Wireless LAN field requires some degree of expertise
in both. The hardware is typically added to an existing system as an extension of the Access Layer requirements of
the network and managing the Air Interface requires another set of skills entirely. One of the best things about
WLANs is that they operate in a license-free band allowing the market to develop products and technologies
through open competition. One of the drawbacks with WLANs is that they operate in unlicensed bands, which
results in increasing radio interference from other devices such as cordless phones. Industry Canada determines
the frequency bands that WLANs operate in and the Institute of Electrical and Electronics Engineers (IEEE)
develops the standards that describe how the technology will work in that spectrum.

Overview of Wireless Technology
LANs, WLANs and Protocols
What Is Wi-Fi?
Wi-Fi stands for Wireless Fidelity. Computers can be equipped with Wi-Fi adapters (which are available as
internally-mounted cards, cards that fit in lap-top PCMCIA slots, or external devices attached via USB ports). WiFi
adapters are fairly inexpensive. The adapters seek out signals broadcast by devices called Access Points
(APs) that in turn are typically connected to the existing wired network. This gives Wi-Fi devices access to the
same resources that devices connected to the wired network have. Although it is less common, Wi-Fi devices
can also communicate directly (one-to-one) with each other. Wi-Fi devices employ several different technical
standards grouped together and referred to as the IEEE 802.11 specification in order to communicate with an AP.
What is the IEEE?
The IEEE (The Institute of Electrical and Electronics Engineers) creates and finalizes standards for computer
networks, amongst other technologies. The IEEE 802.11 specification defines how wireless networks
communicate. As a comparison, most wired networks based on Ethernet and CSMA/CD (defined later)
technology conform to the 802.3 standard.

how can you recover your data once lost????
how
can you recover your data once lost???? Once you realize that you have deleted
a file with or without knowledge and you want to regain it ; you can actually
recover them easily because the original data
( in binary codes) will never be erased unless it is overwritten. Only
copy is deleted while the content is safe. That is the reason generally it
takes long time to copy a large file and seconds to delete the same. Thus data
can be recovered

What will do when liquid spill on the laptop....?
What
can we do if there is a liquid spill on the laptop???Don’t panic!!!Prefer the
following solutions:: Firstly remove the battery and take your laptop to the
service Centre. What if there is a water spill on laptop??? So simple - never
ever turn on the lap ;instead remove both the battery and adapter.
How to increase laptop battery life.
Do we actually have first aid tips for laptops
too???.it sounds wonderful...we at laptoonz
provide various protection measures in different cases...Lets look into
how to increase the battery life of your laptops...Simple!!!! What you can do
is - prevent from keeping your laptop under charging state once it is fully charged..remove the
adapter. Then a question arises : when can you put your laptop to charge? Once
the battery charge drops to 20% then put your laptop to charge..This is
otherwise known as one charge cycle. www.laptoonz.com

HOW IT'S POSSIBLE TO RECOVER DATA FROM HARD DISK
when we copy large size file in to hard disk, need lot of time for completion,
the same think, when we delete same large file its need only seconds,
because the think is that actual file is not delete in the hard disk.
file are just invisible. we will copy other files in same hard disk sector.
first file will totally delete. the same process is continuing. so we can recovery data simply
