IGNOU BCA 1st sem Solved Assignment - Explain the following terms in the context of Internet: (i) MOODLE (ii) Collaborations

Explain the following terms in the context of Internet:

(i)     MOODLE

Collaborations

Ans

Web collaboration provides an organization with the capability to collaborate with customers or internally via the Internet in real time. Web collaboration packages generally consist of Web-based tools within Web sites to assist an organization in the area of sales, new revenue-generation opportunities, and to enhance customer satisfaction. Web collaboration is essentially the back-end software or service that allows your center to share Web pages with customers while offering voice and text chat assistance or to conduct single or multi-user conferences and seminars. Web collaboration can be used in an Internet (IP) environment or integrated with an organizations' existing telephone infrastructure to provide automated customer assistance for a client's Web-based inquiries.

IGNOU BCA 1st sem Solved Assignment - List the names of at least four browsers. List the features that must be supported by a browser. Explain how does browser communicate with the web server?

List the names of at least four browsers. List the features that must be supported by a browser. Explain how does browser communicate with the web server?

Ans

Chrom

Windows only (for practical purposes, but soon on Mac and Linux, if we're lucky): Some browsers have roots going back to the early 1990s—Chrome, on the other hand, is the new kid on the block. Although Chrome has a distant relationship to Konqueror and is a cousin to the Safari web browser—both share the speedy WebKit rendering engine—Google's browser is less than a year old. Despite its youth, it's already garnered praise for its minimalist interface and snappy page rendering. Chrome also handles site errors and quirks well, and each individual tab is a unique process, so a crash or lag in one shouldn't pull down or crash the others. In general, though, Chrome has caught attention for running a performance-focused JavaScript engine in a lightweight GUI. Also worth noting, Chrome has been holding its own in the recent Pwn2Own security challenge, with the distinction of being the only browser left standing after the first day of security exploits and attacks

Opera

Windows/Mac/Linux: Opera is a rock-solid browser with roots stretching back to 1994. Many of the features baked right into Opera are either not implemented in other browsers, or require multiple extensions at the cost of system resources—navigation by mouse gestures is one of the flashier examples. Despite being feature-packed, Opera has a fairly small market share, due largely in part to being trialware up until 2000 and advertisement-supported until 2005—many people were turned off by the expense, if not the ads. Still, Opera proponents have long claimed that Opera beats Internet Explorer and Firefox when it comes to speedy rendering. Another selling point for Opera is the quality of the built-in tools. For many users, the built-in RSS reader, email client, and BitTorrent client do their jobs admirably, cutting down on the number applications they need running at once. Opera is extensible, but the pool of available extensions is radically smaller than that available for Firefox.

Firefox

Windows/Mac/Linux: Firefox is the grandchild of the venerable Mosaic browser and free-roaming son of Netscape. Although Firefox has a myriad of user-friendly, forward-thinking features, a decently secure framework, and an open-source ideology, its most prominent is extensibility. When convincing a Firefox user to abandon Firefox for anything else, even temporarily, you won't have to fight them over giving up the AwesomeBar or about:config tweaks—you'll hear a common, understandable refrain: "What about my extensions?" The repository of extensions maintained by Mozilla currently has over 6,000 entries, covering everything from blocking advertisements, to managing your clipboard, to allowing you to further customize your browsing experience with scripts a la Greasemonkey (here's 10 of our must-have picks). Combine the passion people have for extensions and the ability to sync those extensions across multiple computers and portable installations, and you've got a force to be contended with.

Internet Explorer

Windows only: Internet Explorer still commands a healthy chunk of the browser market, mostly because it ships with the most popular operating system on Earth and fits, if not exactly elegantly, into corporate computer plans. While many or most IE users stick with it for lack of wanting to try something else, Lifehacker readers definitely don't fall into that crowd—the majority of readers who voted in favor of Internet Explorer are sporting Internet Explorer 8. By contrast, nearly 20 percent of those surfing the web right now are using Internet Explorer 6, which had its initial release in 2001. Version 8 could mark a resurgence for the brand, though. It's the first version of Internet Explorer to have a strong focus on web standards compliance, as well as increasing rendering speed. And like Chrome, Internet Explorer 8 maintains a separate process for each tab to increase stability and security. Internet Explorer 8 has also beefed up its security measures from previous versions, including active filtering against malicious cross-site scripting and ActiveX isolation from the core of the browser.

IGNOU BCA 1st sem Solved Assignment - Explain the purpose and functions of TCP/IP protocol. Also define the terms IP address, URL and DNS in this context.

Explain the purpose and functions of TCP/IP protocol. Also define the terms IP address, URL and DNS in this context.

Ans

The Transmission Control Protocol/Internet Protocol (TCP/IP) suite are a set of standards that describe the functions necessary to send data over a network. They are designed to divide the responsibility for the various aspects of data transmission into categories

Features

Rather than write one protocol for each category, specialized protocols cover smaller aspects of each task. This means there are sub-groups of protocols. These groupings are called "Layers," and the layers are represented as levels in a stack. Each layer uses services from the layer below and provides services to the layer above. This principle is called "abstraction."

Function

International open standards enable different companies to write compatible software. When data travels over the Internet, both the sender and receiver have to speak the same language. The TCP/IP protocols provide a common set of procedures and codes everyone follows.

Considerations

The membership of the TCP/IP protocol suite changes constantly. New protocols are added and others are adopted from other systems. The most influential protocol in the suite is the Internet Protocol. This defines the address formats for all devices contactable over the Internet, and is used by all networking systems communicating over the Internet

terms IP address

An IP address is an identifier for a computer or device on a TCP/IP network. Networks using the TCP/IP protocol route messages based on the IP address of the destination. The format of an IP address is a 32-bit numeric address written as four numbers separated by periods. Each number can be zero to 255. For example, 1.160.10.240 could be an IP address.

Within an isolated network, you can assign IP addresses at random as long as each one is unique. However, connecting a private network to the Internet requires using registered IP addresses (called Internet addresses) to avoid duplicates.

URL

Stands for "Uniform Resource Locator." A URL is the address of a specific Web site or file on the Internet. It cannot have spaces or certain other characters and uses forward slashes to denote different directories. Some examples of URLs are http://www.cnet.com/, http://web.mit.edu/, and ftp://info.apple.com/. As you can see, not all URLs begin with "http". The first part of a URL indicates what kind of resource it is addressing. Here is a list of the different resource prefixes:

http - a hypertext directory or document (such as a Web page)

ftp - a directory of files or an actual file available to download

gopher - a gopher document or menu

telnet - a Unix-based computer system that you can log into

news - a newsgroup

WAIS - a database or document on a Wide Area Information Search database

file - a file located on your hard drive or some other local drive

DNS

Stands for "Domain Name System." The primary purpose of DNS is to keep Web surfers sane. Without DNS, we would have to remember the IP address of every site we wanted to visit, instead of just the domain name. Can you imagine having to remember "17.254.3.183" instead of just "apple.com"? While I have some Computer Science friends who might prefer this, most people have an easier time remembering simple names.

The reason the Domain Name System is used is because Web sites are acutally located by their IP addresses. For example, when you type in "http://www.adobe.com," the computer doesn't immediately know that it should look for Adobe's Web site. Instead, it sends a request to the nearest DNS server, which finds the correct IP address for "adobe.com." Your computer then attempts to connect to the server with that IP number. DNS is just another one of the many features of the Internet that we take for granted.

IGNOU BCA 1st sem Solved Assignment - Explain the use of MODEM, Router, Switch and Gateway in the context of Computer Networks.

Explain the use of MODEM, Router, Switch and Gateway in the context of Computer Networks.

Ans

use of MODEM

Basically, modem is used to connect the analog world to the digital world. In other words, you can say it is the device that is used to convert the analog signal to digital signal. For eg. the modem connected with a computer is usually converts the analog signal that comes through the wire to the digital bit bcoz computer can only understands the digital signal...

use of Router

A router is used to route data packets between two networks. It reads the information in each packet to tell where it is going. If it is destined for an immediate network it has access to, it will strip the outer packet, readdress the packet to the proper ethernet address, and transmit it on that network.

use of Switch

A network switch or switching hub is a computer networking device that links network segments or network devices. The term commonly refers to a multi-port network bridge that processes and routes data at the data link layer (layer 2) of the OSI model. Switches that additionally process data at the network layer (layer 3) and above are often called layer-3 switches or multilayer switches.

use of Gateway

A network gateway is an internetworking system capable of joining together two networks that use different base protocols. A network gateway can be implemented completely in software, completely in hardware, or as a combination of both. Depending on the types of protocols they support, network gateways can operate at any level of the OSI model.

Because a network gateway, by definition, appears at the edge of a network, related capabilities like firewalls tend to be integrated with it. On home networks, a broadband router typically serves as the network gateway although ordinary computers can also be configured to perform equivalent functions

IGNOU BCA 1st sem Solved Assignment - Explain the following terms in the context of Operating System: Serial processing Command Processor Multiprogramming UNIX

Explain the following terms in the context of Operating System:

Serial processing

Command Processor

Multiprogramming

UNIX

Ans

. Serial Processing: The Serial Processing Operating Systems are those which Performs all the instructions into aSequence Manner or the Instructions those are given by the user will be executed by using the FIFO Manner means First in First Out. All the Instructions those are Entered First in the System will be Executed First and the Instructions those are Entered Later Will be Executed Later. For Running the Instructions the Program Counter is used which is used for Executing all the Instructions

The Command Processor functionality in Windows Embedded CE includes a command processor shell (Cmd.exe) that is similar to Command.com in Windows 95 and Cmd.exe in Microsoft Windows NT®. The command processor shell is a command-line-driven shell that provides a limited number of commands. The Console Window is available on display-based systems to provide a window through which the Command Processor can provide output and accept input.

The Command Processor requires the Standard IO (STDIO) Catalog item. For headless OS designs, the Command Processor also requires the FormatMessage API and Full C Run-Time Catalog items and either the National Language Support (NLS) Catalog item or the English (US) National Language Support only Catalog item. The Console Window requires the Command Processor Catalog item.

Multiprogramming

To overcome the problem of underutilization of CPU and main memory, the multiprogramming was introduced. The multiprogramming is interleaved execution of multiple jobs by the same computer. In multiprogramming system, when one program is waiting for I/O transfer; there is another program ready to utilize the CPU. So it is possible for several jobs to share the time of the CPU. But it is important to note that multiprogramming is not defined to be the execution of jobs at the same instance of time. Rather it does mean that there are a number of jobs available to the CPU (placed in main memory) and a portion of one is executed then a segment of another and so on.

UNIX

UNIX was one of the first operating systems to be written in a high-level programming language, namely C. This meant that it could be installed on virtually any computer for which a C compiler existed. This natural portability combined with its low price made it a popular choice among universities. (It was inexpensive because antitrust regulations prohibited Bell Labs from marketing it as a full-scale product.) Unix is a multitasking system. This means that Unix has the ability to handle more than one task at a time. These tasks might be several programs that any particular user wants to run, or they may be programs run by several users at once. Multitasking, combined with being a multi-user system, makes it possible for more than one person to be logged in and using a Unix system at once. This is true for any Unix system, not just large timesharing systems. Even small, desktop systems have the capability to support multiple concurrent users. Additionally, some of the tasks that the system could be doing, and probably is doing, can be system tasks related to keeping the system going and providing the services needed by the users.

Explain the uses and/or facilities provided by the following: (i) Tools for Project Management (ii) Compilers (iii) Macros in spreadsheets (iv) Editor Software

Explain the uses and/or facilities provided by the following:

(i)     Tools for Project Management

(ii)   Compilers

(iii) Macros in spreadsheets

(iv) Editor Software

Ans

Project management techniques and project planning tools are useful for any tasks in which different outcomes are possible - where risks of problems and failures exist - and so require planning and assessing options, and organizing activities and resources to deliver a successful result.

Projects can be various shapes and sizes, from the small and straightforward to extremely large and highly complex.

In organizations and businesses, project management can be concerned with anything, particularly introducing or changing things, in any area or function, for example:

·         people, staffing and management

·         products and services

·         materials, manufacturing and production

·         IT and communications

·         plant, vehicles, equipment

·         storage, distribution, logistics

·         buildings and premises

·         finance, administration, acquisition and divestment

·         purchasing

·         sales, selling, marketing

·         human resources development and training

·         customer service and relations

·         quality, health and safety,

·         legal and professional

·         technical, scientific, research and development

·         new business development

·         and anything else which needs planning and managing within organizations.

Successful project management, for projects large or small, tends to follow the process outlined below.

The same principles, used selectively and appropriately, also apply to smaller tasks

uses of Compilers

Compiler is used to convert a language readable in user domain into the tasks which is understood by the machine.

example: C++ compiler compiles program written in a langauge understood by user which compiles this to a task which can be executed by a computer's processor.

uses of Macros in spreadsheets

Excel macros can make your work easier and you more productive by automating common tasks. But there can be a bit of learning curve when it comes to creating your own macros

Macros provide an exceptional method to put little 'programs' into things like spreadsheets. They are easy to create and to modify. They can add tremendous functionality to an Excel spreadsheet. But because they are so easy to create, they are often the first stop for virus writing wanabees. You should be very careful before running any macro; think about whether it might be a virus. But this spreadsheet is safe (if not modified :). If you want, look through the macros - look for commands that would save files, delete files, etc. You should not see any. Instructions are posted.

use of Editor Software

Programming editors, also known as source code editors, are text editors that are specifically designed for programmers or developers for writing the source code of an application or a program.

Most of these editors are built with useful features, which may include colour syntax highlighting, auto indentation, auto complete, bracket matching, syntax check, plugins, etc., to effectively support the users during coding, debugging and testing.
