From the word itself, we can determine that it involves the use of the camera and yes it's true. In fact, if we reflect on meaning, it was the same functions with video cameras and digital cameras except those connected to the computer through a universal serial bus (USB) or better can be built-in on your laptop or PC screen.
Because Webcam mere computer technology, their goals is very dependent on the user / owner. It is widely used by people who want to communicate and see their loved ones, friends and relatives in distant parts of the world's personal without worrying about cost. Some of the other using webcams as part of their security system, even the goal of education and sharing photos.
Webcams Computers consists of a lens, an image or an electronic image sensor and a few supporters. This technology is easy to install but it does not mean that you can only choose. Why? To have webcams Operating System (OS) and processor dependent, so if you plan to get one, make sure that you know your OS and the ability of your processor.
Then, think about the purpose of a camera or better yet ask yourself if what the camera for. Go to a routine if you will only use it for entertainment but if it's for your job, it's better to choose a camera with high quality. But do not think that cameras are usually of low quality. It's just that there is a camera built for some special purpose. But wait, a far better idea is to buy a camera with a built in microphone.
Now, I think you're ready for your hunt for a new computer web cam.
If you want a piece of technology that really will change your life and how you see the technology, a Webcam Computers need to be considered.

Pocket PC, Smartphone and other Windows-based Mobile Communication Gadget technlogy food even VoIP. But of course you need to install third party software which is usually called softphone (software phone) before use. Many softphone substitution can be obtained easily, as SJPhone.
UMPC vs Netbook
Basically these devices, the UMPC and Netbook, designed for users with high mobility.
The form is small and lightweight making it easy to carry two devices everywhere. Spirit of both the device itself is the availability of internet connection via WiFi and the front was supposed to be followed by 3.5 G or HSDPA connection. In Indonesia alone, the use of Internet-based WiFi already widespread in several major cities. In Jakarta, for example, Internet users are surfing while waiting for the plane take off in an airport lounge, it's not an alien thing. University campuses also have Wi-Fi to provide facilities to support teaching and learning activities of students.
Even in public places like city parks, not infrequently have been provided free access berselanjar in cyberspace with Wi-Fi connection. The same phenomenon seen in many cafes, such as Starbucks and Cafe La Mode Cafe in Plaza Indonesia, Coffee Club and Cafe Coffee Bean Senayan in Cilandak Town Square, where visitors can access the Internet to view the artist's political news or the latest gossip while sipping a hot cappuccino. Places that provide Wi-Fi facility is very flourishing. Places where there is Wi-Fi facility is usually called a Hot Spot Area. Every time you make a connection on a Hot Spot with your UMPC or Netbook, you could actually endanger your own UMPC or Netbook. Hot Spot is an open network that does not use encryption so that when you connect with users Hot
Another spot, then they can infiltrate and cause damage to your computer.
But do not let this cause you fear against various Hot Spot because there are several ways to secure your computer when you connect to the Hot Spot, namely:
1. Turn off ad-hoc mode WiFi: WiFi works in two modes namely infrastructure mode, which you use when connected to a network, and ad-hoc mode when you connect directly to another computer. If you turn on ad-hoc fashion then there is likely someone near you using ad-hoc connection without your knowledge and they can get into your PC with free. So do not forget to turn off ad-hoc mode, follow these steps:
1. Right click on the wireless icon in system tray
2. Select Status
3. Click Properties
4. Select the Wireless Networks tab
5. Choose your current network connection

7. Remove the checkmark in the box "This is a computer-to-computer (ad-hoc) network."
8. Click OK and keep clicking OK until all dialog boxes to close
2. Use a Wireless Virtual Private Network (VPN): When you are at a hot spot areas, people laindapat see passwords, user names, email and any yangAnda do online. One of the best ways untukmelindungi yourself is with a wireless VPN which encrypts all information you send and receive them online. One is the Hotspot VPN using VPN software that was built in in Windows XP so you do not need to download
software.
3. Use the USB fl ash drive is encrypted: For maximum protection, use a laptop that is really clean and has only just inside the OS application, and enter all your data into the USB fl ash drive that is encrypted. That way, if someone tried to infiltrate into your PC they will not be able to read or alter your data.
4. Use of personal fi rewall: Firewall will protect you from anyone who tries to get into your computer and prevent the spyware or Trojan from your PC to connect out. For maximum security do not only depend on the innate Windows-fi rewall one direction, but use other rewall fi good. ZoneAlarm provides a free rewall fi is pretty good.
5. Turn off fi le sharing: With you turn it off have helped prevent others from taking fi le of your system. To turn it off, the windows explorer, right click on any drive or folder, select sharing & security and remove the checkmark in the box "Share this folder on
the network. "
6. Make sure you use hot spot official: Ask first clarity on the information at the mall or a cafe where the hot spot because one mode is the existence of fraud hot spot someone who set himself a hot spots in public places to steal your personal information or data.
7. Turn off your wireless adapter if you're offl Magazine: If you're not connected to the internet at a hot spot area, you better turn off your wireless adapter.

9. Consider your surroundings: To steal your passwords and user names, others do not have to use technical means and in fact they only just a little peek enough when you're typing.
10. Never leave your laptop: Of course this is not only inviting hackers, but also a thief.
UMPC vs. Netbook
Once we know each defi technicians on UMPC and Netbook, then we also have seen per-
Direct comparisons between the two devices with Notebook / Laptop, now we will compare both these portable gadgets. From this comparison, you will more easily determine which one would you choose as the gadget of your activity companion.
The main feature of a netbook is:
1. Screen size 7 "- 11". The size of today tend to be 10 ".
2. Small size and light weight - less than 1.5 kg.
3. Work well in Linux or Windows XP. Netbook now most have now include Windows XP.
4. Prices roughly in the range of $ 300 - $ 500.
5. Long battery life to 6-12 hours of usage.
The main features of the UMPC:
1. Screen sizes range from 8 ". The screen is smaller than the net book.
2. Prices are generally higher than a netbook if judging from the consideration of usability you get.
3. Portable or rather 'ultra-mobile'.
4. Using the touch screen, stylus and on-screen key board. Some have a small keyboard.
5. RAM and Hard Disk size depends on the development factory made, but the average UMPC has a minimum of 1GB of RAM and 30-160 GB Hard Disk space.
6. UMPC runs on Intel or VIA processors.
7. Notebook features closer, even some of the UMPC has the optical drive.
8. Battery power is less than a netbook, even though the new models can run up to 10 hours as the Nova Mobility's, the second generation of the Industry Side Arm 2 UMPC.
So, what would you choose? It all depends on the needs and interests of buying a gadget.
Whether for performance, style, mobility, or the other. What is clear winner in the Netbook price, the keyboard, better screen, and battery life. UMPC was brought impression compact (portable) is higher, smaller and more mobile forms, as well as a lightweight and stylish body. Regarding the shortage of each gadget, you can compare your own tour through the fi-fi tour that has been described above. So, congratulations to explore the world of hardware through the UMPC and Netbook

History 3G, HSDPA and EVDO Network
3G was first introduced by NTT DoCoMo in Japan in branding with the name FOMA. Start-known
it in May 2001 and revised again in October 2001. Although there are constraints due to delays in data transmission network realibitas limited. Introducing a second network is SK Telecom of South Korea in 1xEV-DO network in January 2002.Nokia 6650 handset is the first to adopt the UMTS technology. In December 2007, 190 operators in 40 countries have adopted 3G tenology well, as well as 154 Telecommunications Operators in 71 Countries. In the same year, 200 million 3G subscribers already connected. Although the 3 Billion phone subscribers worldwide, only 6.7% of his course. 3G is a wireless communications standard and that the definitive portable nisikan by the ITU (International Telecommunication Union) where this technology in the network including GSM, EDGE, UMTS, and CDMA 2000, DECT and WiMax. Services included in the broad area dare voice, video calls, wireless data, and the environment. Unlike the 2G and 2.5 G which allows the use of 3G data and voice simultaneously with a maximum speed of up to 14Mbit/detik for downstream and 5.8 Mbit / sec for upstreamnya. With this 3G network, operators can more fl eksibel provide network services with more flexibility to maximize Effi ciency in the network.
Evolution from 2G to 4G
2G network is still available as a service to voice and low speed data transmission. From 2G to 2.5 G
A leap in the evolution of 2G is the first technology to introduce GPRS (General Packet Radio Service).
Then combined with voice services and switch its name to 2.5 G. GPRS can provide access speeds up to a maximum 114Kbit/detik 56Kbit/detik. It can access the technology and service WAP (Wireless Application Protocol), MMS (Multimedia Messaging Service) and email communications as well as the WWW (World Wide Web).
From 2.5 G to 2.75G (EDGE)
EDGE (Enhanced Data Rates for GSM Evolution) was introduced in 2003 by AT & T on standardized 3GPP and Amerika.EDGE is one part of the GSM family.
4G evolution
3GPP and 3GPP2 are the extension of 3G technology standards. This is because already has an IP-Network
infrastructure, and with the kembangkannya MIMO network, which is a separate character for IMT-Advanced (4G). 4G standards are capable of reaching speeds diyakinin 1Gbit/detik for downstream and for upstream 100Mbit/detik) This standard has not been achieved. Existing networks and the development of 3G is called 3.9 G or Pre-4G. Qualcomm is the courage to develop this technology. In the month of December 2009, Telia Sonera announced to the world's first 4G technologies to customers. Countries that are able to taste this technology in Stockholm, Sweden, Oslo, and Norway.

It can access the technology and service WAP (Wireless Application Protocol), MMS (Multimedia Messaging Service) and email communications as well as the WWW (World Wide Web).
From 2.5 G to 2.75G (EDGE)
EDGE (Enhanced Data Rates for GSM Evolution) was introduced in 2003 by AT & T on standardized 3GPP and Amerika.EDGE is one part of the GSM family.
4G evolution
3GPP and 3GPP2 are the extension of 3G technology standards. This is because already has an IP-Network
infrastructure, and with the kembangkannya MIMO network, which is a separate character for IMT-Advanced (4G). 4G standards are capable of reaching speeds diyakinin 1Gbit/detik for downstream and for upstream 100Mbit/detik) This standard has not been achieved. Existing networks and the development of 3G is called 3.9 G or Pre-4G. Qualcomm is the courage to develop this technology. In the month of December 2009, Telia Sonera announced to the world's first 4G technologies to customers. Countries that are able to taste this technology in Stockholm, Sweden, Oslo, and Norway.
