Where is the error in this code sequence?

Art [367]

Answer:

There is an error in "String s=s1-s2 ";

Explanation:

In java programming, we can subtract subtract two strings variable with "-" operator.Java programming does not support an overload of the '-' operator.In java, we can use only "+" operator to append two strings variable.There is no such method to subtract strings in java.Therefore in the given code String s=s1-s2 will give an "bad operand type" error because we can not subtract one string variable from the second string variable.

Which of the following is not a true statement about Christopher Columbus it oko

Thepotemich [5.8K]

Answer:

There has been a need to explore the different regions across the globe in the early ages, as there were ships to travel but there was no one before who knew about the different routes and maps of the region, so, it was sort of blind folded traveling when some one wanted to go far distances yet some of them knew about other regions on the far sides of many seas having a unique culture, different languages, along with having diversity among the flora and fauna inside the region.
So, like many other curious people across the globe there was a need for the people to explore all the regions. As, it was a need for the travelers and all the rest of free fork to know about this world. Now, every wanted to know more about the different lands but there were few who even performed the great feat, as they had fear for their lives.While, Christopher Columbus was more into sacrificing his own life in order to explore the lands at the far lands across the Pacific ocean. As, he arranged his mind and covered all the required arrangements for the journey.
As, was at first wanted to explore the lands of far east and thus wanted to more about the Subcontinent India, but in turn he reached the lands of the American continent in far west.While, upon arriving the American region we say many people with different skin tone, culture and language which was very different then he heard about the people of India.There was more different world then he could ever think of as he had a lot to tell about these lands upon the way back to Europe or his home land.

Is the wireless network you own as secure as it should be? Examine your wireless network or that of a friend or neighbor and det

AleksandrR [38]

Answer:

See explaination

Explanation:

Wireless Security:

In a bid to examine the network you can use ipconfig /all command in windows or in the event where you are a linux user type in ifconfig to view all the configuration details of your network such as

indows IP Configuration

Host Name . . . . . . . . . . . . : myvpc-hb

Primary Dns Suffix . . . . . . . : example.com

Node Type . . . . . . . . . . . . : Hybrid

IP Routing Enabled. . . . . . . : Yes

Ethernet adapter Local Area Connection:- - - - - -

Connection-specific DNS Suffix . :- - - - - -

Description . . . . . . . . . . : Intel 68540-Based PCI Express Fast Ethernet Adapter

Physical Address. . . . . . . . . : 00-03-AA-BC-CA-8F

Autoconfiguration Enabled . . . . : Yes

Link-local IPv6 Address . . . . . : fe65::ab56:ccb9:320c:524d%8(Preferred)

IPv4 Address. . . . . . . . . . . : 192.168.45.111(Preferred)

Default Gateway . . . . . . . . . : 192.168.15.1

DHCP Server . . . . . . . . . . . : 192.168.15.1

DHCPv6 IAID . . . . . . . . . . . : 201327615

Note: If you want to deeply examine the your network and to find security model go with Wireshark application.It will help you to capture the data packets easily using GUI.Also it will provide other details like transmission control protocols,etc.

To take your network to highest level i.e. to make it more secure you can use:

1.Firewalls like application gateways,packet filtering,hybrid systems.

2.Crypto cable routers

3.Virtual private networks, etc.

Estimation of cost and the time to increase the level is solely depends on the type of the architecture you want to use for the network building structure.Also the size of the network will be responsible for the cost and time.

In case of any attack on your computer it depends on the size of the data on the computer disc and the bandwidth of the network to which your computer is connected to replace all data. The faster the bandwidth of the network,faster the data replacement rate.
