You cannot tell whether your girlfriend is a virgin unless you are a gynaecologist, which seems unlikely. I do not really understand why this matter is so important to you and why you doubt her word. Does she know that you suspect she is lying to you? I feel that the two of you must talk this subject over carefully.
For the sake of completeness, I should add that when a young woman loses her virginity, there is usually slight evidence in the form of a few drops of blood, but that is not always the case. If your relationship continues and you do eventually have sex with her, please take care to use reliable contraception. Incidentally, you do not say whether you yourself are a virgin
You can use an LG
phone as a modem for your PC c. LG mobile phones are available with various
wireless carriers, and most models are capable of a feature for data and
internet sharing known as tethering.
When tethered, your cell phone acts as a modem and provides an Internet connection
for your PC computer. The easiest way to set up your LG phone as a modem for
your PC computer is to use Bluetooth and configure the network settings through
the Windows interface.
Items you will need

A lot of computer users sometimes
find it very hard to secure softwares partly because of lack of
finances and partly too much love for freebies....................anyways for whatever reasons that may hinder you from securing applications here are some websites to get serial keys and cracks of any software for free
The computer is an electronic machine use for aCCEPTING facts,processing informations,storing and bringing out processed information known as data.
But without a browser your computer might be unable to perform to the fullest(surfing the internet) and below are the major top free browser downloads that may be useful to you.
Android is fast becoming the commonest mobile operating system and in vew of this phone owners which uses android operating system must find a way to secure their mobiles from trojans and some other virus. while surfing the net i came up with the following antivirus suitable for android devices
Android phones use a completely different operating system. This means that, essentially, a virus designed for a Windows operating system wouldn't know how to harm an Android phone, even if it was deep in the CPU.
In view of this listed below are the best antivirus for android devices *Kaspersky
Kaspersky Mobile Security Lite is the free version of Kaspersky’s full Mobile Security app with the main differences being the addition, in the full version, of a SIM watch option in the anti-theft protection, call & SMS filtering plus privacy features (which can hide designated contacts, and controls what others can see and access on your phone).
after installation you need to define a security code which is used by features like the anti-theft protector to activate different commands. There is no option to perform a scan on your existing apps or data but the real time scanning of newly installed apps is enabled by default.
The Lite version is most limited and in many ways just serves as an demo for the full version. During av-test.org tests Kaspersky ranked 4th and the Lite version will do the same job in terms of detecting malware but with limited security functionality. *AVAST
avast! Mobile Security is a free app that includes a not only an anti-virus component but also a wide range of security tools including a privacy scanner, an app manager and a web shield that scans each URL and warns you if it’s a known malware-infected web site. It also includes a USSD blocker which stops any dangerous USSD commands like those discovered for Samsung smartphones in the later part of last year. For rooted devices it also has a firewall.
There is also a large number of anti-theft options including the ability to control your phone via SMS and perform actions like a history wipe, phone lock, and siren activation.
When you first run avast! it will automatically scan your device for any malware that has crept in unawares and then it switches to real-time protection mode. According to the Android antivirus tests carried out by av-test.org, avast is “easy to use and has many features to protect your device. With its very good detection rate it is one of the best security products for your Android device.” *AVG Like many of the apps in this list AVG AntiVirus comes originally from the world of Windows and the humble PC. For Android it comes in two version the free app and the premium PRO version. AVG has come a long way since we checked it in 2012. It was a good product then and it is even better now. The UI has been updated and is much easier to use than previously. After installation you need to manually kickoff the first scan. Until you do the app will show some red warning indicators.
During the first scan AVG noticed that the phone was set to allow the installation of apps from external (unknown) sources. This is set on my device as I have the Amazon appstore installed. AVG is right, this does present a level of risk but the risk factor is low. Ticking “ignore this threat” will make the warning disappear.
Like many of the other anti-virus apps, AVG is more than just an anti-virus scanner. It includes a task killer, a battery optimizer, real time protection from unsafe websites and an anti-theft / phone location service(an addded bonus).
The free version comes most likely comes with a 14 days of access to the PRO features which include an App Locker, which blocks the launching of an app unless the password is entered, and the ability to backup your apps to the phone’s SD card.

*The test was made on 23 April-10 May 2007, using Windows XP Professional SP2 on a P4 3000 Mhz, 1024MB DDRAM.
* All programs tested had the latest versions, upgrades and updates and they were tested using their full scanning capabilities e.g. heuristics, full scan etc.
*The default settings of each program were not used, in order for each program to achieve its maximum detection rate. Because of this, there is a possibility for the tested programs to detect a few false positives.
*All programs were updated on 22 April 2007, between 10.00AM and 13.00PM GMT.
*The 174770 virus samples were chosen using VS2000 according to Kaspersky, F-Prot, Nod32, Dr.Web, BitDefender and McAfee antivirus programs. Each virus sample was unique by virus name, meaning that AT LEAST 1 antivirus program detected it as a new virus.
window users can also check out microsoft secuirity essentials.its awesome and reliable and free too all you need to do is make it up to date.
*ALL virus samples were unpacked and the only samples that were kept were the ones that were packed using external-dos-packers (that means not winzip, winrar, winace etc).

1)Intel Core i7-3770K The raw CPU performance is only slightly better than its immediate predecessor's, but the Core i7-3770K is the first Intel processor we’ve tested with built-in graphics powerful enough to run the latest games, albeit at reduced detail settings. 2) Intel Core i7-3960X Extreme Edition Read Our Review For demanding, CPU-intensive tasks such as video editing, the Core i7-3960X offers unprecedented performance, and its significant overclocking headroom will appeal to tweakers who don’t mind its extreme price. ' Choice Good For Gaming Intel Core i7-3960X Extreme Edition 3) Intel Core i7-2600K
With significant speedups in both single- and multi-threaded applications, a low price, and excellent overclockability, this new high-performance chip is a performance enthusiast’s dream.
4) Intel Core i7-4770K
Intel’s new top consumer CPU boosts integrated graphics a fair bit above last year’s Core i7-3770K, while ticking up slightly faster on our CPU-specific benchmarks.

Two big addition of the Apple product line are the iPad and the iPhone 4. What a lot of people noticed during the unveiling of the iPhone 4 is that it is actually powered by the very same A4 processor. Although they have similarities, they have differences that make them appropriate for certain uses. The biggest difference between them is their size (pun intended). The iPad is almost 7 times bigger than the iPhone but is slightly thinner. The bigger device allows Apple to put better specs into the iPad.
For one, the iPad has a 9.7 inch display while the iPhone has a 3.5 inch display but with only a slightly higher resolution. Despite that, the bigger screen of the iPad makes it much better when watching video or browsing the Internet. You can still do the same with the iPhone but you need to make do with the smaller screen and very frequent zooms when online. The iPad is also equipped with a bigger battery, to provide the same amount of video viewing or browsing time. The iPad has bigger power requirements and installing a battery with identical specs to that of the iPhone would mean lesser available power.
Although the iPad has some advantages over the iPhone, there are also roles that only the iPhone can play. The iPad is not able to make calls or send text messages like the iPhone; after all who would want to hold the iPad to their face to make or receive a call. The iPad was also not equipped with a video camera, so you cannot record videos or even take pictures with it. The iPhone 4 actually has 2 cameras, one on the rear for pictures and video and one in front for video calling.
The iPad only has a few of the sensors you would find on the latest iPhone. The most important sensor right now is the gyroscope which allows for better motion sensing than the accelerometer. It should open up new possibilities for game controls and other stuff. Sadly, the current iPad cannot run those apps since it lacks the gyroscope of the iPhone.
In conclusion The iPad is much bigger than the iPhone The iPad has a bigger battery than the iPhone You can make calls on the iPhone but not on the iPad The iPhone has a camera but not the iPad The iPhone has more sensors than the iPad

Come September 10, the current iPhone rumor season will end and a new one will begin. That's because that's the day Apple will unveil the next incarnation of its iconic device -- that is, if All Things D's unnamed sources have it right.
As expected, the iPhone 5S appears nearly identical to the iPhone 5 save several small distinctions. The first is the previously rumored dual-LED flash on the back of the iPhone 5S. Where every iPhone that's had a back-facing flash thus far has used a single bulb, this next-generation device is aiming to up the ante with a double-dose of bright light.
Remind yourself as we’re running these comparisons down that these devices are quite likely case-maker dummy models, this meaning the final product could very well end up significantly different up-close and personal. Colors are likely quite close, and the locations of buttons are more that likely in their right positions, but detailing will be more precise.
Up front you’ll find a long line atop the iPhone 5S’ display in place of a short line and dot, this suggesting Apple is pushing for a slightly simpler (ever so slightly, that is) design with a single hole rather than two for the earphone speaker and single sensor. The front-facing camera on the iPhone 5S appears to be positioned slightly higher than before and works with a smaller opening than the iPhone 5. The same is true of the back-facing camera, both lens ports being slightly smaller than their predecessors’. It’s not clear at the moment why such a change would be in order, save for a different camera set up front and behind. The bottoms of both devices appear to be exceedingly similar – so similar that we’d estimate any differentiation would be due to the maker of the dummy’s slightly inaccurate machining.
Meanwhile the so-called iPhone 5C looks and feels (to the photographer) to be essentially the same size as the iPhone 5 (and 5S), save its rounded sides and plastic delivery – not unlike that of the iPhone 3GS, an piece of hardware all but lost to time (yes, the iPhone has already been plastic).

A modem
simply stands for (modulator-demodulator)and it is a
device that modulates ananalog
carrier signalto
encodedigitalinformation, and also demodulates such a carrier signal to
decode the transmitted information it lets you connect your computer to a
standard telephone line so you can transmit and receive electronically
transmitted data. Modems are
generally classified by the amount of data they can send in a givenunit
of time, usually expressed
inbits
per second(bit/s,
or bps), orbytes
per second(B/s).
Modems can alternatively be classified by theirsymbol
rate, measured inbaud
Basically there
are 3 major types of modem which are
External modem, Internal modem. PC Card modem.
Now let us address them one after the other
1 external modem This is the simplest type of modem to
install because you don't have to open the computer. External modems have their
own power supply and connect with a cable to a computer's serial port. The
telephone line plugs into a socket on the rear panel of the modem.
Because external modems have their own power supply, you can turn
off the modem to break an online connection quickly without powering down the
computer. Another advantage over an internal modem is that an external modem's
separate power supply does not drain any power from the computer. You also can
monitor your modem's connection activity by watching the status lights.
2 internal modemMost internal modems come installed in the computer you buy.
Internal modems are more directly integrated into the computer system and,
therefore, do not need any special attention. Internal modems are activated
when you run a communications program and are turned off when you exit the
program. This convenience is especially useful for novice users.
Internal modems usually cost less than external modems, but the
price difference is usually small. The major disadvantage with internal modems
is their location: inside the computer. When you want to replace an internal
modem you have to go inside the computer case to make the switch.
3 PC Card modem.
These
modems, designed for portable computers, are the size of a credit card and fit
into the PC Card slot on notebook and handheld computers. These modems are
removed when the modem is not needed. Except for their size, PC Card modems are
like a combination of external and internal modems. These devices are plugged
directly into an external slot in the portable computer, so no cable is
required other than the telephone line connection. The cards are powered by the
computer, which is fine unless the computer is battery-operated. Running a PC
Card modem while the portable computer is operating on battery power
drastically decreases the life of your batteries.
Having
known thesehow do modem works
When a modem first makes a
connection, you will hear screeching sounds coming from the modem. These are
digital signals coming from the computer to which you are connecting being
modulated into audible sounds. The modem sends a higher-pitched tone to
represent the digit I and a lower-pitched tone to represent the digit 0. At the other end
of your modem connection, the computer attached to its modem reverses this
process. The receiving modem demodulates the various tones into digital signals
and sends them to the receiving computer. Actually, the process is a bit more
complicated than sending and receiving signals in one direction and then
another. Modems simultaneously send and receive signals in small chunks. The
modems can tell incoming from outgoing data signals by the type of standard
tones they use.
Modems
convert analog data transmitted over phone lines into digital data computers
can read; they also convert digital data into analog data so it can be
transmitted. This process involves modulating and demodulating the computer’s
digital signals into analog signals that travel over the telephone lines. In
other words, the modem translates computer data into the language used by
telephones and then reverses the process to translate the responding data back
into computer language.
The speed in which a
computer connects to the Internet can vary because of many factors, so the
speed that the ISP posts gives an average or a range that a user can expect
when connecting. Many sites offer free speed testing. One of the easiest to use
is Speakeasy because there is no software to download or install.
steps involved
1 Click on the Internet Explorer icon or any other browser you have on the
computer's desktop or the taskbar.
2Enter the URL
"www.speakeasy.net/speedtest" in the Internet browser address box.
3Choose a server
from the list that is provided to start the testing process.
4 Read the results that will be provided when the test
is complete at the bottom of the graph near the bottom of the page.
5 Consider running the test a couple of times
to get a better reading of the average speed of the computer's Internet
connection.
Tips
& Warnings
·The test can be
run at various times of the day to see when the speed might be faster or
slower. This can aid in deciding when to download or upload a large file or
files.
·Beware of sites
that offer to download and install software on the computer before the test is
run. Most likely, these are spyware or virus sites,
because this test can be completed without installing any software on the
client computer. earlier on i told you that some factors are responsible for your computer network speed. some of these factors are 1 Bandwidth and 2 Latency check out these article to find out about what is bandwidth
Bandwidthin
computer networking refers to the data rate supported by a network connection
or interface. Network bandwidth is not the only factor that contributes to the
perceived speed of a network But we are only concerned with letting you know the basic expaination of what a bandwidth means.
Now what does a Network Bandwidth means?
Bandwidthis the primary measure of computer network
speed. Virtually everyone knows the bandwidth rating of theirmodemor their Internet service that is prominently
advertised on network products sold today.
In networking, bandwidth represents the overall capacity of the
connection. The greater the capacity, the more likely that better performance
will result. Bandwidth is the amount of data that passes through a network
connection over time as measured inbits per second (bps).
Bandwidth can refer to both actual and theoretical throughput,
and it is important to distinguish between the two. For example, a standarddial-upmodem
supports 56 Kbps of peak bandwidth, but due to physical limitations of
telephone lines and other factors, a dial-up connection cannot support more
than 53 Kbps of bandwidth (about 10% less than maximum) in practice. Likewise
traditionalEthernetnetworks that theoretically support
100 Mbps or 1000 Mbps of maximum bandwidth, but this maximum amount cannot
reasonably be achieved due to overhead in the computer hardware and operating
systems.
Broadband and Other High
Bandwidth Connections
The termhigh bandwidthis sometimes used to distinguish
fasterbroadbandInternet connections from traditional dial-up
or cellular network speeds. Definitions vary, but high bandwidth connections
generally support data rates of minimum 64 Kbps (and usually 300 Kbps or
higher). Broadband is just one type of high bandwidth network communication
method.
Measuring Network Bandwidth
Numerous tools exist for
administrators to measure the bandwidth of network connections. OnLANs
(local area networks),someof these tools includenetperfandttcp.
On the Internet, numerousbandwidth
and speed test programsexist, most available for free online use.
Even with these tools at your
disposal, bandwidth utilization is difficult to measure precisely as it varies
over time depending on the configuration of hardware and characteristics of
software applications including how they are being used
There
is another factor that is responsible for the computer internet speed
that factor is called Latency.Although it is less important but you can
on the name to know more about it.

Giving your
computer a wireless internet connection is a very easy task to accomplish all
you need to ask yourself
*Doesyour
computer have a wireless adapter installed?
If your answer is yes
then you are good to go but if your answer is no then you need to check my
article on HOW TO GET AN INTERNET WIRELESS ADAPTER.
If you already have the adapter installed take the following
steps
1 Find out if wireless Internet reception exists where your computer
is located. If you're located very close to a W-iFi hotspot, like a coffee
shop, you may be able to use this network to get wireless Internet for desktop
PCs. Also, some apartment complexes and college dorms have free wireless
Internet. Your neighbors may have wireless Internet too, which you can ask them
if you can use.
2 Buy a wireless network adapter for your desktop if you dont have one already.
You can obtain an adapter from most electronic stores. Be sure to get a
wireless adapter with the proper strength, which depends on how far you are
from the wireless hotspot.
The
easiest adapters to install are those that just plug into an available USB
port.
o
o3
Set
up your wireless Internet for your desktop PC according to the instructions
that came with the wireless adapter. The usual procedure is to plug the
wireless adapter into an available USB port. Windows will install the
appropriate driver. After your PC recognizes the wireless adapter, select the
"Connections" icon in the taskbar (represented by vertical bars). A
list of available connections will appear. Select the desired connection. If
you are prompted for a password, enter the appropriate password. Click
"Connect." You are subsequently connected to a wireless network.
Launch your browser and enjoy surfing the Internet wirelessly.
o4
If
you are the owner of the wireless network, secure your wireless network with a
password. To do so, navigate to the "Start" menu and select the
"Control Panel." Then select "Network and Internet" and
"Network and Sharing Center." Click "Change adapter
settings" in the left pane. Double-click the icon of the appropriate
wireless connection. The Wireless Network Connection status window appears.
Click the "Wireless Properties" button. Select the
"Security" tab and select an encryption type from the drop-down
selection. Enter a password in the Network security key field. Make sure that
the password matches the router settings. Press "OK" when done.
o5
Get
a wireless internet router for your Internet connection if there is no wireless
Internet already in your area. You can buy these online, or at electronic
stores. You'll need to set up your router using the accompanying instructions
and your own Internet service provider. This is best in a home with multiple
computers.
Tips & Warnings
Be sure that you have the proper firewall and security
software on your computer when using unsecured networks.
Verify the wireless adapter's system requirements
before you purchase it to be sure that your computer is compatible.
Don't use another person's wireless connection unless
you're authorized.
Connecting
a computer to the internet is the most important thing to do after getting hold
of a computer system.
Getting a computer system without connecting it
to the internet is just like having a mobile phone without a sim card for
accessing the network as some important features on the device will need
network to work efficiently.
Steps required in connecting the
computer with the internet.
*Connect to the Internet wizard by clicking theStartbutton
*click on Control Panel,
* click onNetwork and Internet,
* click onNetwork and Sharing
Center,
*click onSet up a connection
or network,
* and then clickingConnect to the
Internet.
