Directions for Questions 31-35:Read the passage and answer the questions that follow on the basis of the information provided in the passage.RSS is a family of XML file formats for web-syndication used by news websites and weblogs. The abbreviation stands for one of thefollowing standards:* Rich Site Summary (RSS 0.91)* RDF Site Summary (RSS 0.9, 1.0 and 1.1)* Really Simple Syndication (RSS 2.0)RSS provides short descriptions of Web content together with links to the full versions of the content. This information is delivered as an XML file called RSS feed, webfeed, RSS stream or RSS channel. In addition to facilitating syndication, RSS allows a website’s frequent readers to track updates on the site using a news aggregator.RSS is widely used by the weblog community to share the latest headlines or their full text and even attached multimedia files.A program known as a feed-reader or aggregator can check RSS-enabled Webpages on behalf of a user and display any updated articles that it finds. It is now common to find RSS feeds on major websites, as well as many smaller ones.Web-based feed readers and news aggregators require no software installation and make the user’s "feeds" available on any computer with Web access. Some aggregators syndicate (combine) RSS feeds into new feeds e.g., take all football-related items from several sports feeds and provide a new football feed. There are also search engines for RSS feeds like Feedster, Technorati, Pluck or Plazoo.RSS feeds are typically linked to with an orange rectangle with the letters XML or RSS.As of 2005 multiple versions of RSS exist, belonging to two main pathways:* RSS 0.90 was the original Netscape RSS version. This RSS was called RDF Site Summary, and as such a completely valid RDF format.* RSS 0.91 is the simplified RSS version released by Netscape, and also the version number of the simplified version championed by Dave Winer from Userland.com. Now called Rich Site Summary, this was no longer an RDF format, but was relatively easy to use. It remains the most common RSS variant.* RSS 0.92 through 0.94 are expansions of the RSS 0.91 format, which are (in theory at least) all compatible with each other and with Winer’s version of RSS 0.91, but are not compatible with RSS 0.90. RSS now stood for "Really Simple Syndication".* RSS 1.0 and 1.1 are open formats by the "RSS-DEV Working Group", again standing for RDF Site Summary. RSS 1.0 is an RDF format like RSS 0.90, but not fully compatible with it.

31) Which one of these is NOT a full form of RSS?A) Rich Site Summary B) RDF Site SummaryC) Rich Site Syndication D) Really Simple Syndication

32) RSS provides:A) Short descriptions of Web content. B) Short descriptions of Web content + links to full content.C) File formats for Web syndication for Web sites. D) All the options

33) Which of these does NOT state how one can read Web pages with an aggregator?A) Feed readers check RSS-enabled Webpages for updates. B) Users can log into the feed reader to check for updates.C) All of the above plus Web based feed readers. D) Search engines for RSS can be used.

34) Which was the original RSS version?A) RSS 1.1 B) RSS 0.9 C) RSS 1.2 D) RSS Original

35) Select the FALSE statement.A) RSS 0.91 is the most common variant of RSS.B) RSS 0.9 was the original Netscape RSS. version

CGI enables the webserverto generate dynamic content rather than just return static HTML files. In addition, because CGI can accept and process information submitted by the user, it can provide two-way interaction between the client and the web-server. For example, CGI is commonly used to create dynamic HTML pages from information in a database, or to process user input such as validating a creditcard when a product is ordered online. Many popular internet search engines use CGI. These engines receive search criteria from theuser, process the input, and return the search results. CGI was the first and continues to be the most popular method of buildingdynamic Web sites.Typically, CGI scripts are written in Perl, Tcl, C or a Unix shell, but almost any language can be used, including Java. A CGIapplication works in the following manner. When the web-server receives a request that maps to a CGI application, it executes a CGIprogram that runs in its own process space. The CGI program returns HTML to the web-server, and the web-server returns theHTML to the client. To illustrate, a typical CGI transaction might go like this:1) The server receives a request for a resource called /cgi-bin/guestbook.cgi.2) Either because the file has a .cgi extension or because it is located in the /cgi-bin directory, the server recognizes the file as a CGI request and launches the guestbook.cgi program, passing any parameters received from the client.3) The guestbook.cgi program executes, processing any information passed as a parameter, and returns an HTML document to theweb-server.4) The web-server returns the HTML to the client.To the user, this process is completely transparent. The user simply requested a resource using a URL and received an

Page 8: Nasscom placement paper

HTMLdocument in return. Other than the format of the URL, the user would have no way of knowing that the document was created dynamically on the server rather than simply stored in a static file. Using this process, the web-server can vary its response based on user input. Prior to CGI, this kind of two-way interaction on the web was not possible.One important note is that all CGI applications run as independent processes. Creating a new process for every CGI request hurts performance and is resource intensive. This is in contrast to ’servlets’ that are loaded just once and thereby perform better.31) CGI revolutionized the Internet because:i) Static HTML pages automatically became dynamic.ii) It provided a two-way interaction between the client and the server.iii) One could think beyond static HTML pages.iv) Web-servers were no longer required.A) ii only B) iv and i C) ii and iii D) iii only32) Before the advent of CGI:A) Credit cards were invalid. B) Internet search engines could not exist.C) Since pages were static, they could not contain images. D) Perl, Tcl, C or a Unix shell were never used.33) All CGI applications run as independent processes causing:A) Lower performance and optimal utilisation of resources.B) Enhanced performance and non-optimal utilisation of resources.C) Enhanced performance and optimal utilisation of resources.D) Lower performance and non-optimal utilisation of resources.34) CGI made validation of credit cards possible because:A) The browser client could pass the credit card number to the server.B) Credit card companies accepted the feasibility of online systems.C) It is a standard interface between an HTTP server and an application.D) Internet became more secure and reliable.35) If you are given the task of creating an online web application using CGI, you will definitely need to:i) Create guestbook.cgi.ii) Build dynamic HTML pages by making database requests.iii) Write CGI scripts in a language such as Perl, Tcl, C, Unix Shell, Java etc.iv) Channel client requests through the web-server.A) iii and iv B) i, iii and iv C) Only iii D) ii and iiiQ3) Nasscom Nac-Tech verbal ability questionsDirections for Questions 1-5: Read the passage and answer the questions that follow on the basis of the information provided in the passage.

For a period of more than two centuries paleontologists have been intrigued by the fossilized remains of pterosaurs, the first flying vertebrates. The issues, which puzzle them, are how these heavy creatures, having a wingspan of about 8-12 meters managed the various problems associated with powered flight and whether these creatures were reptiles or birds.

Perhaps the least controversial assertion about the pterosaurs is that they were reptiles. Their skulls, pelvises, and hind feet are reptilian. The anatomy of their wings suggests that they did not evolve into the class of birds. In pterosaurs a greatly elongated fourth finger of each forelimb supported a winglike membrane. The other fingers were short and reptilian, with sharp claws. In birds the second finger is the principal strut of the wing, which consists primarily of feathers. If the pterosaurs walked on all fours, the three short fingers may have been employed for grasping. When a pterosaurs walked or remained stationary, the fourth finger, and with it the wing, could only urn upward in an extended inverted V- shape along each side of the animal's body.

In resemblance they were extremely similar to both birds and bats, with regard to their overall body structure and proportion. This is hardly surprising as the design of any flying vertebrate is subject to aerodynamic constraints. Both the pterosaurs and the birds have hollow bones, a feature that represents a savings in weight. There is a difference, which is that the bones of the birds are more massively reinforced by internal struts.

Although scales typically cover reptiles, the pterosaurs probably had hairy coats. T.H. Huxley reasoned that flying vertebrates must have been warm-blooded because flying implies a high rate of metabolism, which in turn implies a high internal temperature. Huxley speculated that a coat of hair would insulate against loss of body heat and might streamline

Page 9: Nasscom placement paper

the body to reduce drag in flight. The recent discovery of a pterosaur specimen covered in long, dense, and relatively thick hair like fossil material was the first clear evidence that his reasoning was correct.

Some paleontologists are of the opinion that the pterosaurs jumped from s dropped from trees or perhaps rose into the light winds from the crests of waves in order to become airborne. Each theory has its associated difficulties. The first makes a wrong assumption that the pterosaurs hind feet resembled a bat's and could serve as hooks by which the animal could hang in preparation for flight. The second hypothesis seems unlikely because large pterosaurs could not have landed in trees without damaging their wings. The third calls for high aces to channel updrafts. The pterosaurs would have been unable to control their flight once airborne as the wind from which such waves arose would have been too strong.

1 As seen in the above passage scientists generally agree that:a the pterosaurs could fly over large distances because of their large wingspan.b a close evolutionary relationship can be seen between the pterosaurs and bats, when the structure of their skeletons is studied.c the study of the fossilized remains of the pterosaurs reveals how they solved the problem associated with powered flight he pterosaurs were reptiles-Answere Pterosaurs walked on all fours.

2 As inferred from the passage, the skeleton of a pterosaur is distinguishable from that of a bird by thea. length of its wingspanb. hollow spaces in its bonesc. anatomic origin of its wing strut-Answerd. evidence of the hooklike projections on its hind feete location of the shoulder joint joining the wing to its body.

3 From the viewpoint of T.H.Huxley, as given in the passage, which of the following statements is he most likely to agree with?a. An animal can master complex behaviors irrespective of the size of it's brain.-Answerb Environmental capabilities and physical capabilities often influence the appearance of an animal.c Usually animals in a particular family group do not change their appearance dramatically over a period of timed The origin of flight in vertebrates was an accidental development rather than the outcome of specialization or adaptionThe pterosaurs should be classified as birds, not reptiles.

4 The organization of the last paragraph of the passage can best be described as:a. New data is introduced in order to support a traditional point of view-Answerb Three explanations are put forth and each of them is disputed by means of specific informationc. An outline of three hypotheses are given and evidence supporting each of them is givend Description of three recent discoveries is presented, and their implications for future study are projectede The material in the earlier paragraphs is summarized and certain conclusions are from it.

5 According to the passage, some scientists believe that pterosaursa. Lived near large bodies of waterb Had sharp teeth for tearing foodc Were attacked and eaten by larger reptilesd Had longer tails than many birdse Consumed twice their weight daily to maintain their body temperature.

Directions for Questions 9-10: Read the passage and answer the questions that follow on the basis of the information provided in the passage.As India and Pakistan discuss peace at the level of the government, there is an active process of engagement taking place on the internet. In the past, Indians and Pakistanis may have hounded each other on internet chat forums but now, there is a sense of peace and harmony on some sites, where diverse and open ended conversations genuinely bring people closer.Huma Imtiaz Ali, a Content Development Associate at AAG TV, resides in the port city of Karachi. She is often found busy punching in her reply to a post about the Kashmir issue on an Indo-Pak discussion forum that she’s part of. "The usage of mediums such as Orkut, Facebook and blogging websites has widely increased in over the past year or so, and has helped bridge gaps between the India and Pakistan," said Huma. "Every time there is an issue related to the subcontinent, I log on to Sepiamutiny.com or chapatimystery.com to read the views of Indian expats, and to get an idea of what their thoughts might be," she added. "I useFacebook.com on the other hand to interact with people my age from the other side of the border, where we talk about rather fun topics such as about gossip in Bollywood, favourite movies, TV shows, etc, which has made me realize that despite 60 years of separation, we are still very much alike," Huma adds.The issues discussed on such forums tend to be diverse but the aim of these websites is much the same - to encourage interaction between youth on either side of the border. And it was one such website that forged a cross-border friendship. "In my last year at art school, my class was in the process of planning an educational trip to India. Since we didn’t know the specifics about how to plan the trip, where to stay, and what to see first, I attempted to get some information by posting a topic on the Pak/India community on orkut (which is wildly popular both here and across the border)," said Khizra Munir, Creative Executive,Interflo Communications Ltd, Karachi. "A Delhiite replied to my ’plea’ and after exchanging email addresses we exchanged information. We later went on to meet him in Delhi, he took us around Janpath and he continues to be a friend," she said.Often enough, such forums can provide a common ground for complete strangers as Flickr.com did for Ali Khurshid and Jaya. "My maternal grandparents came to Pakistan from Bhopal and have forever told me so many stories about the little village with the one hill and the big lake and the small lake that the entire setting has occupied a legendary status in my mind, says Ali Khurshid, a secondyear student at the Indus Valley School of Art and Architecture, Karachi. "Around a year ago I met Jaya, also from Bhopal who was posting pictures from this "magical" place. For starters I was stunned by how close the images in my mind were to the pictures she had and secondly we became friends in spite of the illusory walls of religion, nationality and prejudice that would have otherwise come in between us," said Ali. In absence of all other means of communication, cyberspace is fast becoming one most important means of dialogue between the youths of

Page 16: Nasscom placement paper

India and Pakistan. Such interactive forums are a small yet positive step in the right direction but only time will tell if measures like these will change mindsets and bridge the gap created by 60 years of separation between the two countries.

Page 23: Nasscom placement paper

Records are stored in files using a file organization that determines how the records will be stored, located, and retrieved.

Sequential organization is the simplest way to store and retrieve records in a file. In a sequential file, records are stored one after theother without concern for the actual value of the data in the records. To read a sequential file, the system always starts at the beginning of the file and reads its way up to the record, one at a time. The system does not care what data values are stored in the fields within a record. In fact, sequential files do not use physical record keys; records are accessed in order of their appearance in the file. (For this reason, analysts refer to sequential files as non-keyed files.)

In contrast to sequential organization, processing a direct-access file does require the system to start at the first record in the file.Direct-access files are keyed files. They associate a record with a specific key value and a particular storage location. All records are stored by key at the address rather than by position; if the program knows the record key, it can determine the location address of arecord and retrieve it independently of every other record in the file.

Direct addressing should have a data set with the following characteristics:1. The key set (I.e., the range of key values assigned) is in a dense, ascending order with few unused values (unused values mean wasted storage space). Therefore few open gaps in the key values are wanted.2. The record keys correspond to the numbers of the storage addresses: there is a storage address for each actual or possible key value in the file and there are no duplicate key values.

In a dense key list, for each key value there is a storage space with an address that is equivalent to the key. The key values are also in a close sequence; there are few skips in the sequence. This is important in the file design since, when storage is assigned for the file, it starts at the lowest value and extends to the highest key value. Skips in the range of keys results in wasted storage space. Storage must be allocated even though it will go unused.

Another problem prohibiting use of direct addressing arises when the keys for the records do not match storage addresses. Even if the analyst want to use direct addressing, it is impossible to do so if key values and addresses do not correspond. For example, if keys contain characters (e.g., a key of AB1CD), direct addressing is not possible, since there is no address for AB1CD.

When direct addressing is not possible but the direct access is necessary, the analyst specifies the alternative access method of hashing. Hashing (also called key transformation or randomizing) refers to the process of deriving a storage address from a record key. An algorithm (an arithmetic procedure) is devised to change a key value into another value that serves as a storage address.

Indexed OrganizationThe basic form of index includes a record key and the storage address for a record. To find a record when the storage address is unknown (as with direct address and hashing structures), it is necessary to scan the records. However, the search will be faster if an index is used, since it takes less time to search an index than an entire file of data.

An index is a separate file from the master file to which it pertains. (For this reason some of analysts refer to it as a detached index.) Each record in the index contains only two items of data: a record key and a storage address. (It does not duplicate each data item in the master file record.)

To find specific record when the file is stored under an indexed organization, this index is first searched to find the key of the record wanted. When it is found, the corresponding storage address is noted and then the program accesses the record directly. This method uses a sequential scan of the index, followed by direct access to the appropriate record. The index helps speed the search comparedwith a sequential file, but it is slower than direct addressing.
