Q.2. Sarvesh, a student of Class X, is not able to understand the difference between web client and webserver. Help him in understanding the same by explaining their role and give suitable example of each.
Differentiate SMS and MMS.
Web-Client: An application (Web Browser, Chatting Program, etc.) that requests for services from a web-server.
Example: A Web Browsers, Chatting Applications.
Web-Server: Web-server is software (or any dedicated computer running this software) that serves the request made by the web-clients.
Example: Apache Server
Q.3. Write HTML code for the following:
To provide hyperlink to a website “http://www.cbse.nic.in’’
www.cbse.nic. in </a>
Q.4. Explain CSS with reference to DHTML.
CSS is a style sheet language used for describing the look and formatting of a document written in a markup language. It is a way to provide style to HTML. Whereas the HTML is the document of content, the style sheet is the presentation of that document. DHTML is merely a browser feature or enhancement that gives your browser the ability to be dynamic.
Q.5. What is the difference between HTTP and HTTPS?
Q.6. Mention the services which are provided by transactional category of an e-banking.
(i) There are no geographical barriers and the services that can be offered at a minimum cost.
(ii) Through Internet banking, you can check your transactions at any time and as many times as you want to.
(iii) If the fund transfer has to be made outstation, where the bank does not have a branch, the bank would demand outstation charges, whereas with the help of online banking, it will be absolutely free for you.
(iv) Internet banking deploys the Internet as a medium for financial transaction. e.g. a customer login to his or her bank account by accessing the bank Website.
Q.7. In how many ways can we access the internet?
Students use the Internet quite frequently to study. Discuss the advantages and disadvantages of this for the student.
In the following ways, we can access the internet:
(i) Dial-up Connection: It uses a telephone line or cable to dial into an ISP and a modem attached to a computer. The ISP helps establish a modem to modem link, which is then routed to the internet. The user is connected temporarily to the internet through any service provider.
(ii) Broadband Connection: It is a high speed Internet access. Broadband connectivity doesn't even disturb the telephone use. It carries both voice and data over a single wire. Voice uses the lower end of frequency spectrum while the data uses the higher end. Broadband connection speeds are measured in mbps (megabits of data per second).
Broadband service is available in three ways:
(a) Cable Modem
(b) DSL (Digital Subscriber Line)
(iii) Wireless Internet Connection: It involves the use of technologies such as Wi-Fi, WiMAX and satellites. The wireless technology uses radiowaves and microwaves for transmission of data.
(i) Latest information available.
(ii) Easier to produce neatly presented work.
(iii) Huge amount of information.
(iv) Faster access to information.
(i) Danger of accessing doubtful websites.
(ii) Inefficient searching.
(iii) Credibility of information.
(iv) Can get easily distracted.
Q.8. Read the case study given below and attempt any 4 sub-questions (out of 5):
Mobile technology is a technology where the user uses mobile phone to do the operations related to communication system, for example to establish communication with friends, relatives and others. It uses to transmit the data from one system to others. Mobile Technology consists of portable two way communications systems, computing devices, and the related networking equipment. Mobile technology is a technology which is used primarily in cellular communication system and other related aspects. It uses a network type in which several transmitters are able to send data on a single channel at the same time. This model is known as Code-Divisions Multiple Accesses . This platform allows many users to use single frequencies, as it limits the possibility of frequency interference from two or more sources. Over the years, the channel has grown. Mobile technology is evolving rapidly; its applications are becoming increasingly diverse over the years and are gradually replacing some similar sources on the market that are also used for communication, e.g. post office and land lines. Mobile technology has improved from a basic phone call and texting device into a multi-tasking system used for GPS navigation, internet browsing, gaming, instant messaging, etc. With the rise, professionals argue that computer technology's future depends on wireless networking and mobile computing. Mobile technology is becoming more and more popular through tablets and portable computers.
(i) In which one code with specific characteristics can be applied to the transmission?
(ii) Out of TCP, GPRS and GSM offers packet mode data transfer service over the cellular network?
(iii) Out of CDMA, TDMA and FDMA enables us to use the entire bandwidth simultaneously?
(iv) Mobile Computing allows transmission of data from one wireless-enabled device to another.
(v) GSM stands for.
(i) Code Division Multiple Access (CDMA)
(ii) General Packet Radio System (GPRS)
(iv) Wireless-enabled device
(v) GSM stands for Global System for Mobile Communications.
