We have to use Pen drive for several purposes in our daily life. If Pen drive got affected by virus then sometimes it becomes so difficult to format it. In this situation we have to find out an alternate way to format it. If you can't format Pen drive in general way then press on "Windows Key + R" to open your RUN window, then write "cmd" and press ENTER. Now you will see a command prompt , there you write "format M" then press ENTER twice. This process sometimes takes longer time to execute but it is effective. You can also format your Pen drive from control panel. In the control panel click twice on "Administrative Tools" and then you will see "Computer Management",  click on that twice. Now you should see a option saying "Management" in the left, click on that option. Now in the right side you should see the list of your every drive including Pen drive. Give a right click on Pen drive and then format. I think these processes will help you to successfully format your Pen drive for safe uses.

I used to play legos 17 years back when I was child. May be that day is not much far away from now  when I will be playing it again, it is sure that I won't play with legos but I will play with smartphones. Yes, cellphone manufacturing company Motorola has been collaborating on a mission with Dave Hakkens to bring out such a phone which you can find very similar to legos. You can break this phone into several parts and again you can join them. You can swap any part of it very easily with the other phone's part.  So, get ready to play with your smartphone instead of legos.

The internet uses a system of telecommunications protocols that has become so widely used that it is now accepted as a network architecture. The internet's protocol suit is called Transmission Control Protocol/Internet Protocol and is known as TCP/IP. An IP address can be either dynamic or static. A static address is one that you configure yourself by editing your computer's network settings. This type of address is actually rare, and it can create network issues if you use it without understanding of TCP/IP. Dynamic addresses are the most common. They are assigned by the Dynamic Host Configuration Protocol(DHCP), A service running on the network. DHCP typically runs on network hardware such as routers or dedicated DHCP servers. Dynamic IP address are issued using a leasing system , meaning that the IP address is only active for a limited time.If the lease expires, the computer will automatically request a new lease. Sometimes, this means the computer will get a new IP address, too, especially if the computer was unplugged from the network between leases. This process is usually transparent to the user unless the computer warns about an IP address conflict on the network. An address conflict is rare, and today's technology typically fixes the problem automatically.
