Networks are built with a mix of computer hardware and computer software. Further, you do not need the same software package installed on your machine, if your network has that software installed on one of the machines on the network.

In this sense, computer networks are clear means for sharing resources. This makes the use of computer technology cost effective. Following Figure 5. If you explore more on computer networks, you will come across with a huge list of terminology associated with networks. Let us look at the basic terminology used in the subject of computer networks in brief. It is worth to note here that all networks are made up of basic hardware building blocks to interconnect network nodes.

A node can be a computer or some other device, such as a printer. A client may be a PC or a workstation on a network using services provided from the network file server, or it may be that part of an application program that runs on the workstation supported by additional software running on the server.

One of the most familiar clients is the Web browser. In large networks, a dedicated server runs a special network operating system; in smaller installations, a non-dedicated server may run a personal computer operating system with peer-to-peer networking software running on top.

A server typically has a more advanced processor, more memory, a larger cache, and more disk storage than a single-user workstation. A server may also have several processors rather than just one and may be dedicated to a specific support function such as printing, e-mail, or communications. Many servers also have large power supplies, UPS uninterruptible power supply support, and fault-tolerant features, such as RAID technology.

On the Internet, a server responds to requests from a client, usually a Web browser. In some star networks, a hub is the central controlling device. Hubs typically provide from 4 to 24 connections, allowing anything from 2 to 24 devices to communicate with one another.

Although IP addresses are stored as binary numbers, they are often displayed in more human-readable notations, such as The role of the IP address has been characterized as follows: "A name indicates what we seek. An address indicates where it is. A route indicates how to get there. It provides physical access to a networking medium and often provides a low-level addressing system through the use of MAC addresses. Figure 5. In most twisted pair Ethernet configurations, repeaters are required for cable which runs longer than meters.

Bridges do not promiscuously copy traffic to all ports, as hubs do, but learn which MAC addresses are reachable through specific ports. Once the bridge associates a port and an address, it will send traffic for that address only to that port. Bridges do send broadcasts to all ports except the one on which the broadcast was received.

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.

Network topology Bus network topology Arrangement of components Star network topology. You may use PANs to communicate among the personal devices or you may connect even to higher level networks or to the internet. Ex: a school See Figure 5.

The defining characteristics of LANs, in contrast to Wide Area Networks WANs , include their much higher data transfer rates, smaller geographic range, and lack of a need for leased telecommunication lines. LANs can be small, linking as few as three computers, but often link hundreds of computers used by thousands of people. The development of standard networking protocols and media has resulted in worldwide propagation of LANs throughout business and educational organizations.

The Figure 5. Wide Area Network WAN Wide Area Network is defined as a group of computers and network devices connected across large physical areas such as states or countries. Computers connected to a Wide Area Network are often connected through the telephone system. They can also be connected through leased lines or satellites. The largest WAN in existence is the Internet. You will learn about Internet in a coming section.

Further a MAN is a network that connects two or more Local Area Networks or Campus Area Networks together but does not extend beyond the boundaries of the immediate town, city, or metropolitan area. See Figure 5. As per the above Table 5. Deep discussions on the topologies are beyond the level of this course unit.

However, brief descriptions on each topology and images of them are given below. Bus networks not to be confused with the system bus of a computer use a common backbone to connect all devices.

A single cable, the backbone, functions as a shared communication medium that devices attach or tap into with an interface connector. A device wanting to communicate with another device on the network sends a broadcast message onto the wire that all other devices see, but only the intended recipient actually accepts and processes the message. Many home networks use the star topology.

A star network features a central connection point called a "hub node" that may be a network hub, switch or router. Compared to the bus topology, a star network generally requires more cable, but a failure in any star network cable will only take down one computer's network access and not the entire LAN. If the hub fails, however Figure 5. In a ring network, every device has exactly two neighbors for communication purposes. All messages travel through a ring in the same direction either "clockwise" or "counterclockwise".

A failure in any cable or device breaks the loop and can take down the entire network. Ring topologies are found in some office buildings or school campuses.

Mesh Topology Mesh topologies involve the concept of routes. Unlike each of the previous topologies, messages sent on a mesh network can take any of several possible paths from source to destination.

Recall that even in a ring, although two cable paths exist, messages can only travel in one direction. Some WANs, most notably the Internet, employ mesh routing. As shown in the illustration below, partial mesh networks also exist in which some devices connect only indirectly to others. Tree Topology Tree topologies integrate multiple star topologies together onto a bus.

In its simplest form, only hub devices connect directly to the tree bus and each hub functions as the root of a tree of devices. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies.

The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web WWW and the infrastructure to support email. With the dramatic rise in demand for connectivity, the Internet has become a communications highway for millions of users.

The Internet was initially restricted to military and academic institutions, but now it is a full-fledged conduit for any and all forms of information and commerce. Internet websites now provide personal, educational, political and economic resources to every corner of the planet.

Did you know? The foundation of the internet began in , when the US Department of Defense created ARPAnet, a project to allow military personnel to communicate with each other in an emergency. By , the number of internet users worldwide reached 2. To store all of the information on the internet, you would need over 1 billion DVDs or million Blu- ray discs. You are already aware what the Internet is. Accordingly, the internet which is a worldwide system can be accessed by any person or by any organization.

Since it is a vast public communication tool, some organizations were willing to maintain their own local network which supports their employees or the members. The Intranets were developed as a solution to the above requirement. However, the intranet also has almost all the services provided by the Internet, but it is a private system. The access of an intranet is restricted to the authorized members or people within the organization such that the authorized members need to log on with a secure password.

More comprehensively, intranets are private networks based on Internet Technologies that are located behind an organizations firewall. A Firewall is a set of technologies designed to protect a private network from users on a public network.

Some intranets provide access to the Internet through a special server called a Proxy Server, designed to cache to store for quick re-use frequently requested information to keep that information readily available. This type of proxy server also provides tools for tracking and controlling access to networks. An intranet can cover a LAN where only staff in the same building or region can use it. Or it can run over a WAN where staff authorized people from around the world can log in.

Intranets usually start by publishing web pages about the organizations events, health and safety policies, and staff newsletters. Popular applications follow, such as forms to reclaim expenses or request holidays. All these help eliminate paperwork and speed up workflows of the organization. As more features are added, this intranet can become essential to the operation of an organization. It becomes a portal that provides access to all the things workers need.

A typical intranet may provide the services such as E-mail, File transfer, Real time chat, web pages, video and audio streaming services. Each service requires at least one server to provide the service. For example, the intranet of the Open University of Sri Lanka maintains two main servers; a web server for the OUSL web site and a Moodle server for the service of delivery of on-line courses.

Commercial or confidential data is kept secured within the organization. E-mails remain private and may also be encrypted. High bandwidth. No connection limits unlike the Internet. The organization will have dedicated IT personnel to keep things running smoothly.

Information specificity tailored to the organization or staffs needs can be published. We can consider an Extranet as an extension to the Intranets what we described above. Because, the extranets are again private networks that contains information related to the company and accessible only for the members of the company BUT allowed for outside individuals as well who have obtained the authority to access. Therefore, an extranet is partially accessible to authorized outsiders.

An extranet can be configured set up either using a direct leased line linking all intranets or by using a secured separate link created across the participants as a VPN Virtual Private Network.

The latter method is more cost effective than the firs method. Advantages of Extranets A cost effective method to share and trade information and all other data effectively at any time to the authorized people internal and external such as the customers, partners, investors, suppliers who are included within the built up extranet.

A platform for companies to conduct business-to-business deals. Can assist in strengthening relationships between two or more organizations. Useful when the staff of the company works outside the office, from their homes, or sales sites so that they can still be in with the company network with the access permission.

Aim: This session aims to outline the uses of computers in the day to day life and comprehensively model the environmental effects as well as the physical impacts.

Describe why the computers are used at places of work Identify the different sectors where the concepts of ICT are used Briefly describe what e-commerce, e-banking, and e-medicine are Describe the nature of the environment of a computer based work area Identify the health issues related to working with computers Describe how to protect our environment by bad effects from computers.

You might have not seen a place of work without a single computer in use. The computer has become such essential equipment for almost all places of work no matter if it is a small scale or large scale company. Computer literacy in varying extents has become an essential item under the qualifications required for most of the job vacancies. However, the utilization of computers may vary from place to place depending on the nature of the business they perform.

When we consider the both private and government sector places of work in Sri Lanka, following can be considered as the typical uses of computers. Managing data keep track of data about customers, products, demographics and other information important to the business, uses secured mechanisms for storages.

Maintain financial status Keep track of the financial status of the company on an annually, monthly or even day-to-day basis. Spreadsheet software is commonly used to track expenditures, sales, and profit and losses. Accounting software provides a business with even more assistance with financial matters, as it is used to do payroll, invoice customers, prepare taxes and execute other essential functions.

Companies can use their computers to print checks for payroll and expenditures, and can form a direct link to the company's bank account. CommunicationUses e-mails, publishes information on web, keeps in touch with stake holders via social networks, conference meetings avoids the need of physical availability of participants of the meetings, Networking- shares resources, common database of files accessible for authorized members Research work Investigate new products, improve the quality of the existing products through effective research.

So it is not a marvelous fact that most of the organizations move towards automating the tasks with the help of modern computers. We looked at the usage of computers in a typical office in the previous section. It was quite difficult to list of uses as it is vast. However, it can be clearly identify the sectors where ICT is now used in the Sri Lanka and in the world, in general as listed below. Note that the following list is given in general but not specific to our country.

Some of the sectors may be already familiar to you in your everyday life. ICT as a subject i. However, you will be able to get more familiar to use the computer for your studies not only this course unit but also the other courses you follow at OUSL by using your computer as a tool to support your studies.

This category is often referred to as e-learning. We will be discussing deeply about e-learning in session 25 in this course material. However, the following description is given as it is worth to get a brief idea on what e-learning is before proceeding to the next sections. As per a definition given in an international journey, e-learning, sometimes termed computer- based training CBT , internet-based training IBT or web-based training WBT , includes all forms of electronically supported learning and teaching, including educational technology.

The information and communication systems, whether networked learning or not, serve as specific media to implement the learning process. Accordingly you can see that the term e-Learning is really just an umbrella term which covers a wide set of electronic educational applications and processes. Mostly, the electronic technology used here is the use of computers with the accessibility to the internet.

You will be able acquire and develop your knowledge so that you will be able to demonstrate the particular topic learned which proves that it has positively influenced in your behaviors. The advantages of e-learning with respect to both teaching and the learning parties can be considered as; Cost effective Saves time without sacrificing quality Minimizes travel cost Can be accessed from anywhere any time in the world Consistent course delivery Individual instruction.

It makes them be quick, cheap, and more attractive to the client of their business. One of the major applications of ICT in businesses is the existence of industries where buying and selling of products or services done through internet or other computer networks. This area is called Electronic Commerce or E-commerce. You will learn what e-commerce is deeply in session 25 of this material.

However, again for your benefit, a brief description of e- commerce is given below before moving on to the next topic. Online shopping and electronic payments can be considered as the most famous examples of e- commerce. In online shopping, the seller creates their sales outlet in the web while the buyer brows and purchase products with mouse clicks.

For an example, Amazon. Suppose that you need to buy a mobile phone online from amazon. This mechanism is known as electronic payments. Paying through your credit card is an example for an electronic payment.

This type of e-payments very effective and you do not need worry about the safety as the reliable shopping destinations such as Amazon. Basically, the banks store all their customers account details on computers. This allows them to easily find out account information on their customers, and make changes to their account balance easily, for things such as when money is put in and withdrawn from the bank. Have you ever used an ATM card? Hopefully the answer is yes. You may know that you can perform some of your banking activities without the physical movement into the bank.

In another words, you do your banking online. This facility is known as E-Banking. You may do banking with authorized access by logging to the site with your credentials.

E-Medicine is one of such facility. E- Medicine is an online clinical medical knowledge database with a collection of thousands of articles, images, videos which support you to browse and get knowledge in any matter related to the medicine field such as details of diseases, drugs, medications, health news, first-aid guides, etc. Further, you can get the answers for your own health care related question as well. These knowledge databases usually get updated regularly to provide an updated knowledge to the client.

Having read the previous sections of this session you might now have the feeling what a vast range of uses we get from out computers today. Computer, being such common equipment used by people no matter a kid or an adult; did you ever think whether you are working in a good computer based environment? Did you ever think that there are specific guide lines to use your computer with respect to its physical environment?

How many hours do you spend a day in front of the computer? You might not thought of these types of questions before. Following sections discuss about the computer based good working environment and the facts that you need to keep in mind and obey as a computer user.

You may think that you have arranged the furniture and the computer equipment correctly, but still it may give health issues arise if the working environment is poor. Following are the physical aspects that you need to consider with respect to a good working environment. Working space Location of workstations Lighting Decor Atmospheric conditions Noise Housekeeping A briefing of each above aspect is given below. Working space You must have enough space to perform your tasks safely and comfortably.

The amount of working space depends on the user, nature of work you do, and the devices and the furniture you need to use. Everything should not be crowded. Sometimes, you get stressed or less productive when the space is too compact. Therefore, you need to make sure that your work space gives you a good comfortable posture and that you have easy access to and from the location of your computer. Location It is important to think about the visual environment when locating your computer with other peripherals.

Here, the arrangement of lighting, the type of light fittings used, and the location of the window are important to consider. The office layout should be planned around the position of light fixtures to prevent walls or partitions blocking or creating shadows over the work area.

If the user is sitting near photocopiers and printers they may be distracted by noise and the heat generated by the other machines and also may get disturbed by the people who are coming often to operate those other machines. Make sure that you have an easy access to hardware and power points.

Well positioned power points can prevent use of multi-plug boards and extra cable lying. Some instances like using LCDs or if the user is an older person, then you may require high level of lighting. Your lighting should be: Adjustable in direction and intensity level Does not produce excessive contrasts in different regions of your working area Does not result in glare or screen reflections at nearby users.

Glare may cause visual discomfort and may cause headaches as well as reduces the performance of the user. Decor Too much of dark colors can create contrasts in brightness so that additional lighting is needed. As a general rule the ceiling should be brighter than walls and walls brighter than the floor. Atmospheric conditions It is a known fact that people react strongly when they think the air is stuffy, stale or polluted and may express this as general dissatisfaction with the environment.

So your working area should be well ventilated and have a comfortable temperature. You may use air conditioners to satisfy this condition.

Generally, the more complex a task, the lower a users tolerance for noise is. So it is required assure that your work area is minimized with noise. Housekeeping Good housekeeping is promoting maintenance of good health and safety in your work place. So the floors should be tidy and cleaned, environment should be dust free, and it is required to make sure that the power cables do not present tripping hazards. They are: Physical discomfort, pain, or injury Visual discomfort Stress Fatigue These may often influence each other.

Let us have a look at each issue separately. Physical discomfort, pain, or injury It may give several physical discomforts by working with computers. These may affect the parts of your body like muscles, connective tissues, tendons, ligaments, joints, bony structures, the blood supply, nerves and the skin.

Pain Fatigue Muscle discomfort Stiffness Burning sensations Weakness Numbness Tingling You may get these symptoms in different extents, and sometimes may get worsen gradually. However, it is important to take corrective actions as soon as symptoms present. The small changes you can make avoid bigger discomforts. Following are two specifically identified health issues which come under the category described above.

Carpal Tunnel Syndrome: The Carpal Tunnel is an area on the palm side of the wrist bordered on one side by the carpal bones and on the other by the Carpal Ligament, a fibrous band.

This structure is quite rigid. If the space in between the structure gets shrink, the structures within the tunnel gets an increasing pressure. Repetitive movement at the wrist, as occurs with prolonged use of a computer keyboard can lead to inflammation in the carpal tunnel and the resultant painful syndrome. Patients usually feel pain in the forearm area as well as numbness in the affected hand in the thumb, index, long and radial half of the ring finger.

This numbness often occurs at night. The treatments vary from wearing wrist splints, anti-inflammatory medications, or surgeries. Neck and Back Pain: Poor positioning of the keyboard and monitor in relation to the user can lead to discomfort of the neck and back.

The monitor screen should be at a level such that the user can easily see the screen with the head held at a comfortable and neutral position. If the head has to be constantly turned or tilted in order to see the screen, this will lead to chronic aches and pains in the neck area.

This along with any eye strain that occurs can lead to tension headaches. The chair or keyboard stand should be adjusted so that when sitting with the hands resting on the keyboard, the elbows should be slightly above the wrists. The chair should have firm lumbar support and it is important that the individual maintain good posture to minimize back strain.

Visual discomforts The symptoms such as sore eyes, red eyes, watery eyes, dry eyes, blurring of vision and headaches may say that you are about to a vision problem due to computer work.

So it is required to take following precautions to avoid such health issues. Adjustments to the work environment, such as lighting or window treatments to reduce glare and minimize variations in light levels.

Reducing visual stress from computer work through, for example, the use of rest or alternate task breaks throughout the workday, or frequently looking into the distance to reduce focusing fatigue.

Adjustments to computer software, such as ensuring that the font, font size and screen display settings meet the visual needs of the user. Specific lenses to meet the unique demands of computer work, such as lenses that are focused for the distance of the computer screen, lens designs that incorporate near and intermediate focusing distances, and lens tints or coatings that may help to maximize vision and comfort.

A programme of optometric vision therapy. Some computer users may experience problems with eye focusing or eye coordination that cannot be adequately corrected with lenses but may be correctable in other ways. Stress Stresses may cause due to problems at office or home. Some stresses are avoidable while some are unavoidable. Following are some examples avoidable stresses as it is worth to identify them as they can be avoided:.

Working for too many hours each week Working in a situation that is poorly set up for the work being done No performance feedback or only adverse feedback A good support both from outside work and in the work place may strengthen the computer users capacity to deal effectively with work stress.

It is important to remember that for most people work is good for health and wellbeing. Fatigue You may feel either physically, mentally, or emotionally fatigue due to bad computer use. Common approaches for preventing fatigue and discomfort when using computers include pauses, regular breaks, stretching and task variety, knowing deadlines and negotiate to get achievable deadlines, break large tasks into small parts, have plans to achieve deadlines and targets, etc.

Place the mouse in an easy reach zone so that the shoulders and upper arms can be relaxed and close to the body while operating the mouse. Keep the wrist and hand in a neutral position, never bent. Keep arm and hand in line See Figure 6. Use alternative devices on the market such as graphic tablets and pens, touchpad, touch screens, and foots witch-operated mice.

Use mouse wrist supports to elevate the hand and wrist if feel better when using. Position the monitor so that you do not have to bend the neck up or down or twist the neck sideways to view the screen. The top of the display screen should be at or slightly below eye level and at about 18" to 24" away from the face.
