Each sub-part carries 1 mark. The unreadable message can be converted to the original message by the receiver at the destination. Caesar Cipher is one of the common encryption techniques. In this technique, each letter of the word is replaced by a letter some fixed number of positions (usually called as key) down the alphabet. For example, if the key is 3, each ‘A’ will be replaced by ‘D’ (Letter ‘D’ is 3 positions down Letter A’ in the alphabet), each ‘B’ will be replaced by ‘E’ and similarly, each ‘Z’ will be replaced by ‘C’. The receiver can identify the original message by using the reverse technique of encryption. This reverse technique is called decryption.<\/p>\n Question 1.<\/p>\n (A) Data can be accessed by any unauthorized person during transmission.

World Wide Web World Wide Web (WWW) or simply web is a set of programs, standards and protocols that allows the multimedia and hypertext files to be created, displayed and linked on the Internet. The World Wide Web was invented by British scientist Tim Berners-Lee in 1989 while working at CERN. It became publicly available on Internet for the first time. The Internet is the physical network of computers all over the world. The World Wide Web is a virtual network of web sites connected by hyperlinks (or “links”). Web sites are stored on servers on the internet, so, the World Wide Web is a part of the Internet. In 1969, the US Department of Defense, approved a project named ARPANET (Advanced Research Projects Agency Network). In 1970, NSF created a common network called CSNET. A more speedy network NSFnet was built. In 1995, a new name was given to the collection of all networks and was called Internet.<\/p>\n Question 1.<\/p>\n (A) World Wide Web Explanation: Question 2.<\/p>\n (A) ARPNET Explanation: Question 3.<\/p>\n (A) WWW Explanation: Question 4.<\/p>\n (A) 1950 Explanation: Question 5.<\/p>\n (A) Advanced Research Projects Agency Network Explanation: Question 6.<\/p>\n (A) 1988 Explanation: Question 7.<\/p>\n (A) Hyperlinks Explanation: Question 1.<\/p>\n (A) be a pentium machine Explanation: Question 2.<\/p>\n (A) 3 Explanation: Question 3.<\/p>\n (A) a binary string Explanation: Question 4.<\/p>\n (A) URL Explanation: Question 5.<\/p>\n (A) microsoft.com Explanation: Question 6.<\/p>\n (A) 2 Explanation: Question 7.<\/p>\n (A) 256 Explanation: Internet Basics Class 10 MCQ Questions with Answers Question 1.

\nUniform Resource Locator (URL) or website address refers to the addressor the location of a web page or the website on the Internet. Each website on the Internet has a unique address. For example, http:\/\/www.google.com is a URL. The first part of the URL is called a protocol identifier and it indicates what protocol to use, and the second part is called a resource name and it specifies the IP address or the domain name where the resource is located. The protocol identifier and the resource name aTe separated by a colon and two forward slashes. “http:\/\/www.google.com”. In the above URL, “http” is the protocol identifier and “www.google.com” is the resource name.<\/p>\n
\nI. Secure data transmission Secure data transmission means that data\/ information is not being received or modified by an unauthorized person, over a network, from source to destination. For secure data transmission, we can convert an actual message (which is in readable form) into an unreadable message (called an encrypted message) with the help of the concept of encryption. This unreadable message is sent through the network to the destination. If a hacker tries to read this message, he\/she receives an unreadable message that cannot be easily converted into the actual message.<\/p>\nSecure data transmission means :<\/h2>\n
\n(B) Data can not be accessed by any unauthorized person during transmission.
\n(C) Transmission of data
\n(D) None of the above
\nAnswer:
