11. Write the summary of the text "Computer Network".

Ans:

Computer networks link computers locally or by external communication lines and software protocols, allowing data to be exchanged rapidly and reliably. The distinction between local area and wide area networks is, however becoming unclear. Networks are being used to perform increasingly diverse tasks, such as carrying email, providing access to public databases, and for distributed system. Networks also allow users in one locality to share resources. Distributed system use networked computers. Similarly, PCs or workstations provide the user screen handling. Mainframe process queries and returns the results to the users. A user at his PC might make a query against a central

database. The PC passes the query, written in a special language, to the mainframe which then parses the query, returning to the user only the data requested. This allows both the network and the individual PC to operate efficiently.

In the 1980s, at least 100,000 LANs were set up world-wide. As synchronous orbit satellites have lowered the price of long-distance telephone calls, data can be transmitted more cheaply. In addition, fibre-optic cable has been installed on a large scale, enabling vast amounts of data to be transmitted at a very high speed using light signals. This will considerably reduce the price of network access, making global networks more and more a part of our professional and personal lives. Networks should also improve our work environments and technical abilities. In this way, the text computer network provides what networks are and how they operate.

OR

Mary Evans, Gerry Hasper, Matt Andrews and Bob Bolton are well known software developers. Do they think software purchases are getting what they need? What are their views about giving a better product to purchases?

Ans:

Software technology is getting more complicated; Mary Evans, Gerry Hasper, Matt Andrews and Bob Bolton are well known software developers. These four well-known software developers have to cut through a jungle of computer languages, operating environments and shifting standards to choose how they will create their software. However, it is not easy task, software buyers will have to live with the result for years to come. The software developers think that the software purchases are getting what they need. In their views, the developers are now working for giving better product to purchases.

In Mary Evans' opinion, customers are getting what they want. There are a lot of creative things being done with paint software, word processing desktop publishing (DTP) systems. The computer is an incredibly powerful tool and any software that make it easier, faster, more creative or more cost- effective. She says that he is optimistic about the way things are going at the moment and most of the major software manufacturers are able to understand the market well.

Gerry Harper's idea is that they are not getting the technical support they need. While the products are getting more complex and expensive; it seems that support is starfing to be thought of as an additional business opportunity. The applications are getting too big. They are versatile and powerful and overwhelming.

Matt Andrews opines that suppliers know what their customers want and they just can't supply it quickly enough. Purchasers' need seem always to exceed the capability of the available software by a constant time frame of nearly six to twelve months.

Likewise, Bob Bolton argues that the users are getting what they want and provided that their needs fit the off-the shelf application. Software should be written in house for business. Developers should add features that the customer needs but not what they think customers want. Some effort should be made to get feedback from the users before making an upgrade so that the proper features are added.

2. What are the major functions of the decision support system? Explain.

   Ans: Decision Support System (DSS) is a set of manual or computer-based tools that assists in some decision-making activity. In today's business environment, decision support systems (DSS) are commonly understood to be computerized management information systems designed to help business owners, executives, and managers resolve complicated business problems or questions. Good decision support systems can help business people perform a wide variety of functions, including cash flow analysis, concept ranking, multistage forecasting, product performance improvement, and resource allocation analysis. Previously regarded as primarily a tool for big companies, DSS has in recent years come to be recognized as a potentially valuable tool for small business enterprises as well.

   Gupta, Jatinder, and Thomas Harris, in their "Decision Support Systems for Small Business" published in the "Journal of Systems Management" in February 1989, observed that DSS is predicated on the effective performance of three functions: information management, data quantification, and model manipulation. "Information management" refers to the storage, retrieval, and reporting of information in a structured format convenient to the user. Data quantification involves the condensing and analytical manipulation of large amounts of information into a few core indicators that extract the essence of data. Model manipulation encompasses the construction and resolution of various scenarios to answer 'what if' questions. It includes the processes of model formulation, alternatives generation, and solution of the proposed models, often through the use of several operations research/management science approaches. Thus, the decision support system has three broad functions: information management, data quantification, and model manipulation.

3. How has micro-chip technology changed the world forever? Illustrate.

   Ans: The micro-chip is pervasive and ubiquitous in our lives more than we realize. One of the enablers that have really transformed our lives in the last 40 years was being the successful development of semiconductors or microchips. It has gone from being an incredibly simple device that was used in the early days of microchips people that advertised a two transistor radio, a three transistor radio. And because they were replacing what used to be called tubes. But then, the industry moved very rapidly towards integration. So, we created the integrated circuit soon after we created the microprocessor. And all of that just exploded in terms of the applications that they went into. It is estimated today that the people from the time they wake up in the morning to the time they go to bed get somehow exposed and touch something on the order of 500 microprocessors. So, we can think of it as touching 500 computers. We're probably not aware we did that but, every time we get in our car which can potentially have in excess of 100 microprocessors in the automotive electronics. So, it's around US everywhere. Our phones, our laptops, our iPads all of those things we're now surrounded by this technology. And the impact upon the world made by it has been enormous. The widespread availability of computers has in all probability changed the world for ever. The microchip technology which made the Personal computer (PC) possible has put chips not only into computers, but also into washing machines, cars, books, etc. Some books may not be published in paper form, but may be made available as a part of public databases. Networks of computer are already being used to make information available on a world-wide scale. These all cases show that the micro-chip technology has become a catalyst of change in the world.

4. Give the meaning of "network of networks" and then explain the main use of ALGOL

Ans: The Internet is often described as a network of networks. Some include the Connecting devices that are the connectors to join one part of the larger network to another. Connecting devices differ in complexity of the connection they provide, but they all contribute to the rapid movement of data that is the key to the Information Age. Computers can deal with different kinds of problems if they are given right instructions for what to do. Instructions are first written in one of the high-level languages, eg FORTRAN, COBOPL, ALGOL, PL/1, PASCAL BASIC, C and API.

ALGOL is an acronym for ALGorithmic Language called International Algebraic Language (IAL). It is a family of portable programming languages for scientific computations developed in the mid-1950s that had a strong influence than those of many other languages. Additionally, ALGOL was used as the standard method for creating algorithms by the ACM (Association for Computing Machinery) in textbooks and academia. It is used for mathematical and scientific purposes. It was first introduced in Europe in 1960.

There were three major specifications, named after the years they were first published:

ALGOL 58 originally proposed to be called IAI, for International Algebraic Language.

ALGOL 60 first implemented as X1 ALGOL 60 in mid-1960. Revised 1963.

ALGOL 68-introduced new elements including flexible arrays, slices. parallelism, and operator identification. Revised 1973.

ALGOL has made the network of networks possible. Since internet has connected everything of the world together it has been taken as network of networks.

5. Give some specific names of clip board computers now available in the market and then explain the two different jobs of 'infector' and 'detonator.

Ans: The clipboard is portable board with a clip at the top for holding papers. The clipboard is also known as pasteboard which is a special location in computer's memory that temporarily stores data that was cut or copied from a document. It will hold its information until cut or copy something else, or log out of the computer. The names of clip board now available in the market are GRIDPad, Sony's Palmtop and Canon's Al Note.

An infector is something which transmits a disease or virus. It means, it inserts malicious code into executable files files used to perform certain functions or operations on a system. The part of virus first copied somewhere before the detonator part damages the data on disk. Detonator is a device used to set off an explosion or other destructive process. It erases a vital part of hard disk, making the files on that part of the disk no longer accessible. It works by interfering in some way with the normal use of the computer.

6. Why did the developers of the PAL system invent interlaced video? What are its advantages and disadvantages? Explain.

Ans:  The interlaced video Phase Alternating Line (PAL) is television terminology system. It is used to describe a color encoding system that is used in broadcast television systems in most parts of the world. There was not enough bandwidth to transmit all 625 lines of one TV image in a fiftieth of a second. The advantage is that it eliminates the flicker for viewing from several yards, but for close-up viewing it could cause a headache.

Advantages of PAL TV systems are related to 625-line/50 Hz television systems. PAL TV systems are predominant in Europe. DVDs that can be played on these systems are accordingly labeled as 'PAL. There is a greater number of scan lines within a PAL system this means more picture detail. It's decoder adds color signals of successive lines while canceling out phase errors. Nowadays, the PAL TV system is the most common and prevalent television system found in more than 65 countries because of it excellent color stability. There are different brands of PAL TV systems available today it is up to choosing the best brand and model we want depending on our budget and our entertainment requirements. The advantages of PAL system are following

Greater number of scan lines-more picture detail.

Wider luminance signal bandwidth (4.43 MHz in most PAL variants)

Stable hues - due to error correction by phase alternation

Higher gamma ratio (2:8) - hence, higher level of contrast

Easy studio mixing compared to SECAM

Likewise, the disadvantages or some problems in using PAL are given below:

Costliest receivers due to complex circuits for electronic switching

Lower frame rate hence, more flicker.

Lower S/N ratio than NTSC.

Variable color saturation cancelling out phase differences by alternation holds hue stable but at the same time, it can change (reduce) color saturation

7. "Computers are about to take people to places they have never been able to visit before." Explain the statement basing on the essay "Fancy a fantasy Spacecraft?"

Ans: Of course, computers are about to take people to places they have never been able to visit before, ie. including the surface of other planets. This phrase comes closer to real life than anything on stage or screen. Artificial worlds are being built up in a computer memory so that people can walk through at will, look around, and even touch an object which is called virtual reality. It is an image that has the virtues of a real object without the substance.Virtual reality systems are being developed throughout the world for a range of uses including enabling people to walk 'inside' nuclear power stations, while controlling a robot that actually goes into an area in which no human could live and conducting architects through a computer-generated building before it is constructed.

British scientists have a world lead in virtual reality which sees it as a technology for the next century. Robert Stone, of the National Advanced Robotics Research Centre at Manchester University, is developing systems that could put men on Mars without shooting them into space and could plunge divers under the North Sea without taking them out of the office.

As for example, a virtual reality system consists of a helmet with a color display in front of each eye, and wide-angle lenses to cover the entire field of view and give a stereoscopic effect. The helmet contains sensors, rather like electronic compasses, to record where it is pointing. A computer calculates what the wearer should be seeing in that direction and displays it on the screen. The helmet has a pair of liquid crystal displays with wide-angle lenses giving a stereoscopic image, and a set of magnetic sensors to tell the computer what the helmet is looking at as it moves.

In more advanced systems, the operator wears an electronic glove that detects exactly what the fingers are doing and transmits the information to the computer. If the user tries to pick up something, the computer will make the object follow the hand to give the illusion of carrying it. Pads in the latest type of gloves press into the insides of the fingers and palm when an object is encountered, to create the illusion of feeling it. However, complete 'exoskeletons' covering the user and allowing the computer to simulate almost anything possible in real life are still in the laboratory.

Similarly, a fire-fighter in a nuclear power plant, for example, would move through a computer model wearing an exoskeleton, while a robot would move through the real thing. The computer program will be derived from the data used to design the plant in the first place. The first game is a fighter simulation. Another is based on a sequence in the film, Return of the Jedi, in which flying motor-cycles race through a forest. The computer can link and control several helmets at once for a group game.

Mr. Stone has developed a data glove with air pockets that are inflated to give a sensation of touch in collaboration with Air-muscle, the supplier of the pneumatic systems that made the Spitting Image puppets really spit. The biggest initial market is likely to be for a new generation of video games. W Industries, of Leicester, recently launched a virtual reality system for video arcades. The system, called Virtuality, consists of a cockpit in which a player sits, wearing the helmet, at a set of controls that can mimic bobsleigh, a space-ship, or whatever the imagination of the games programmer can devise.

In this way, the use of computers in different activities and aspects has made even impossible things to possible and computers are about to take people to laces they have never been able to visit before.

8. Discuss some of tasks/jobs suited to robots only, and show the impact of robotics revolution felt in modern society.

a. Welding: Robots excel in welding tasks, as they can handle heavy and cumbersome materials with precision and consistency.

b. Carrying components: Robots are capable of efficiently transporting components from one location to another within a limited timeframe, reducing manual labor and improving productivity.

c. Spray painting: Robots are commonly used for spray painting tasks, as they are unaffected by toxic fumes and can ensure uniform coverage with minimal overspray.

d. Assembling components: With their high precision and repeatability, robots are ideal for assembling intricate components, ensuring accuracy and consistency in the final product.

e. Operations in hazardous environments: Robots equipped with sensors and cameras can operate in hazardous environments such as nuclear reactors and underwater environments, where human access is limited or dangerous.

The impact of the robotics revolution on modern society is profound. It has led to the automation of many tedious and hazardous tasks, freeing up human workers for more skilled and intellectually demanding roles. As robots increasingly take on repetitive and dangerous jobs, human workers are transitioning to roles that require problem-solving, creativity, and innovation. This shift towards knowledge-based work is reshaping industries and driving the demand for highly skilled workers. However, there are also concerns about the potential impact of automation on job displacement and income inequality, highlighting the need for thoughtful policies and strategies to ensure a smooth transition to the future of work.

Addressing Food Insecurity: A Community Approach

Food insecurity is a pervasive issue affecting millions of individuals and families worldwide, including those in my own neighborhood. Despite living in a developed country, many individuals struggle to access an adequate and nutritious diet due to various socioeconomic factors. In this essay, I will explore the problem of food insecurity in my neighborhood and propose a community-driven approach to address it.

Understanding the Problem:

In my neighborhood, food insecurity manifests in various forms. Some families struggle to afford nutritious food due to financial constraints, while others face limited access to grocery stores offering fresh produce. Additionally, factors such as unemployment, low wages, and inadequate social support exacerbate the issue, leaving many individuals vulnerable to hunger and malnutrition.

Impact of Food Insecurity:

The consequences of food insecurity are far-reaching and detrimental. Children from food-insecure households are more likely to experience developmental delays, poor academic performance, and long-term health issues. Furthermore, adults may suffer from chronic diseases, mental health problems, and reduced productivity due to inadequate nutrition. Additionally, food insecurity perpetuates cycles of poverty and inequality, further widening existing social disparities.

Current Efforts and Limitations:

While various organizations and government initiatives aim to alleviate food insecurity, their efforts often fall short of addressing the root causes of the issue. Food banks and meal programs provide temporary relief but do not address the underlying systemic factors contributing to food insecurity. Moreover, reliance on charitable assistance may stigmatize individuals experiencing food insecurity and undermine their dignity.

Proposed Solution: A Community-Centered Approach

To address food insecurity effectively, a comprehensive and community-driven approach is necessary. This approach involves collaboration among stakeholders, including local government, businesses, nonprofit organizations, and residents, to implement sustainable solutions. Here are key components of the proposed approach:

1. Establishing Community Gardens:

Community gardens offer a sustainable solution to food insecurity by providing residents with access to fresh produce and empowering them to cultivate their own food. By converting vacant lots or underutilized spaces into productive gardens, communities can increase food sovereignty and promote healthy eating habits. Additionally, community gardens foster social connections and collective resilience, strengthening community bonds.

2. Supporting Local Food Systems:

Promoting local food systems, such as farmers' markets, food cooperatives, and urban agriculture initiatives, can improve access to nutritious food while supporting local farmers and producers. Encouraging residents to purchase locally grown produce not only stimulates the local economy but also reduces dependence on imported and processed foods, which are often less nutritious.

3. Enhancing Food Education and Skills:

Education plays a crucial role in addressing food insecurity by empowering individuals with knowledge and skills to make healthier choices. Community-based nutrition workshops, cooking classes, and gardening tutorials can equip residents with practical skills to grow, prepare, and preserve their own food. Moreover, educational programs targeting children and adolescents can instill lifelong habits of healthy eating and food literacy.

4. Advocating for Policy Change:

Addressing systemic factors contributing to food insecurity requires advocacy for policy change at the local, state, and national levels. Policies aimed at increasing access to affordable housing, healthcare, and living wages can mitigate the root causes of poverty and hunger. Additionally, advocating for equitable food policies, such as expanding access to nutrition assistance programs and regulating food environments, can create a more just and resilient food system.

5. Fostering Community Engagement and Empowerment:

Central to the success of any community-driven approach is active participation and engagement from residents. By involving community members in decision-making processes, planning, and implementation of food security initiatives, stakeholders can ensure that solutions are responsive to local needs and priorities. Furthermore, fostering a sense of ownership and empowerment among residents promotes sustainability and long-term resilience.

Conclusion:

In conclusion, addressing food insecurity requires a multifaceted and community-centered approach that addresses the underlying causes of the issue while empowering individuals and communities to take action. By implementing initiatives such as community gardens, supporting local food systems, enhancing food education, advocating for policy change, and fostering community engagement, we can work towards building a more equitable and resilient food system. Through collective efforts and solidarity, we can create a future where everyone has access to nutritious and affordable food, ensuring the well-being and dignity of all individuals in our neighborhood and beyond.
