Local Area Network (LAN)

Local Area Network (LAN): In a LAN two or more computers or node are directly linked within a small well defined areas such as a room, office, building, campus or a local neighborhood with a range of 10 kilometers. Each hardware device on a LAN such as computer or a printer is called a node. Most LANs are privately owned, controlled and managed by a single person or organization and uses direct high speed cables to share hardware, software and data resources. LAN uses the Institute of Electrical and Electronic Engineers (IEEE-802.5, IEEE 802.3), Ethernet, IBM token ring, etc standardization protocol where as WAN uses TCP/IP, HTTP, FTP, etc.

The main component of LAN are discussed below-

A) Cables and Other Medium for Transmitting Signal: Cables and other medium for transmitting the signal is one of the very important components of any network. The cables can be of the following types-

a) Twisted Pair: It is used in low speed LAN using base hand transmission. In this mode of transmission data is transmitted as simple electrical levels often without any modulation. There is no multiplexing and the entire bandwidth of the medium is used for transmitting signals from one station. It is used for communication up to a distance of 2 km.

            Twisted pair is vulnerable to interference from large machines such as air conditioners. This interference can destroy data.

            Twisted pair cables are generally two types-

i) Shielded Twisted Pair (STP);

ii) Unshielded Twisted Pair (UTP);

            Twisted pair consists of a pair of insulated conductor’s that is twisted together.

b) Co-Axial Cables: It is used for broadband transmission of speeds of 10 Mbps or more. The broadband transmission uses modulation techniques and is suitable for transmitting high speed and multiplexed data. It consists of a solid conductor running coaxially inside a solid or braided outer annular conductor. The two kinds of co-axial cables are

i) Baseband Co-axial Cables: It can carry only one signal at a time, but it is fast (10 million bits per second).

ii) Broadband Co-axial Cables: It can carry more than one signal at a time. Cable TV companies use broad band co-axial cables.

c) Fiber Optic Cables: Fibre optic can be described as a transmission system employing a light-emitting source – turned on and off rapidly by electrical impulses whose emissions are sent through glass pipe to a light sensitive receiver to convert the changing light intensities back into the electrical impulses. The “core” of fibre optic cables is a very thin strand of highly refined cylindrical glass. A second layer of glass called clad surrounds the core. The clad is fured directly to the core so that it is very difficult to see the boundary between the two with naked eyes. Fibre optic cables are unaffected by magnetic or electrical interferences. They are however expensive and hard to install. The fibre optic carries data at the rate of 100 Mbps.

d) Line of Sigh Transmission: Here data are sent into air transmitted by infrared, lasers, microwaves and radio.

i) Wireless LAN: Wireless LAN uses infrared or radio wave transmission. Although wireless LAN are more prone to error and interception they do not require laying cables and moving it when a node is relocated.

e) Satellite Transmission: In many network fibre is used as backbone to distribute the network, while the last mile wiring is still some type of copper. Some network architecture has limitation on cable distances and the number of workstation that can be supported on as single segments. Exceeding these may result in inconsistent poor or absent network service to nodes beyond the limit. In some cases the entire network can be affected.

B) Fibre Connector: There are several different types of fibre connectors that includes the following:-

a) ST: This keyed, bayonet style (twist-lock) connector is widely used.

b) SC: The SC connector used internationally is a snap-lock connector with a duplex connection, one each to transmit and receive.

Other connectors in the fibre arena includes SMA connectors which are rapidly becoming obsolete and proprietary and specialized connectors that are not as widely used.

C) Controlled Mechanism: The controlled mechanism consists of the following units-

a) Cable Interface Unit: Sometimes also called as hub. It sends and receives signals on the network cables. This unit is a box outside the computers.

i) Hub: Hub acts at the data link layer, acting as a breakout box signals they receive and is the common wiring point for a star topology. It forwards packet to all active ports and shares the bandwidth.

ii) Switches: It works at layer 2 of OSI reference model and checks the destination address and makes a virtual path to the destination port. It does not share band width.

iii) Routers: It works at layer 3 of OSI reference model. Its job is to send packets created by higher layer of the network to the ultimate destination.

            If a network has less number of node, the choice should be 10/100 hubs. If it consists of number of nodes and dispersed in different floor / building your best choice will be switch.

b) Network Media Connector: The connector used to attach network media to the networking devices are called networking media connector. Some of the commonly used network media connectors are-

i) Register Jack 11:

ii) Register Jack 45:

iii) BNC (Bayonet Neill Concelman Connectors):

c) Structured Cabling: A structured cabling system consists of outlets which provide the user with RJ45 presentation, which is again enabled back to a Telecommunication Closet (TC) using an individual cable containing four twisted pair. This cabling is known as horizontal cabling which is again connected back to the back  of the user outlet by means of an Insulation Displacement Connection (IDC) connector.

            The maximum length of cables between the hub and any outlet must be 90 metre to comply with EIA/TIA and ISO requirements. The standard allows a further 10 metre for connecting leads and patches leads making a total drive distance of 100 metres.

D) Node: Each hardware device on a LAN such as computer printer is called a node.

a) Network Card: The Network Interface Card (NIC) is the main physical device which sends and receives data from network cables. A network interface card must be installed at every host that wished to connect to network. The NIC is inserted into an expansion slot inside the computer. The card is connected to the cable interface unit by wire.

            LAN can be connected by a bridge, a router or a gateway. If two LANs are similar one can use a bridge to connect them with two or more similar LANs one can use a router to connect them. With two dissimilar LAN one can use a gateway. The gateway translates the LANs difference data format.

In case of LAN, the accesses are generally done through Switched Access, Contention or Multiple Accesses and Token Passing Access.

The Contention or Multiple Accesses is used in bus topology. In this technique if a line is unused a terminal or device can transmit its message at will but if two or more terminals initiate message simultaneously, they must stop and transmit again at different intervals.

The Token Passing Access is used in ring topology. In this system to deliver a message one should hand over addressed note to a rider (the token) on the many go round that would drop it of at the appropriate place.

            There are also other techniques like reservation access, load adaptive access, tree structure based access, etc.

Some of the need and advantages of LAN are-

a) Resource Sharing: Networking is needed for sharing of:

i) Hardware: The Mainframe computer, super computer, Laser Printer, etc.

ii) Software: For sharing costly software, such as LibSys.

iii) Information: Data, text, audios, videos, picture, databases, etc

b) Distance, Cost, Time, and Space: Networking is needed for breaking the barrier of distance, cost, time and space.

c) Organizational Infrastructure: LAN improves the existing organizational infrastructure.

d) High Speed: LAN provides high speed networking when compared with other network.

e) Low Error Rates: LAN provides accurate data transmission.

f) Internet Access: A LAN in turn often connects to other LANs, and to the Internet or other WAN. All users of the LAN network can share a common line to the internet.

Some of the disadvantages of using LAN are -

a) Distance Covered is Limited: The distance that can be covered by LAN is limited.

b) Number of Terminal is Restricted: Number of terminal to be added to the network is also limited.

c) Initial Cost is High: Many people consider the cost in setting up the LAN as high investment.

Most LANs are built with relatively inexpensive hardware such as Ethernet cables, network adapters, and hubs. Wireless LAN and other more advanced LAN hardware options also exist. Specialized operating system software may be used to configure a LAN. For example, most flavors of Microsoft Windows provide a software package called Internet Connection Sharing (ICS) that supports controlled access to LAN resources.

E-Document

1. Introduction: The information sources which are in electronic format and which are communicate via the electronic media are called electronic documents and in brief e-documents. The electronic media is a computer based media for storage and dissemination of information.

2. Characteristic of E-Document

i) The information are exists in a digital format or computer processable format.

ii) Information are published by releasing them to a central database or in the form of CD Rom, DVD Rom, etc.

iii) E-document can embed text, static picture, sound, animation, motion picture and various tactile modes of communication.

iv) Processing, presentation, storage, display, communication is carried out through the use of digital technology.

v) E-documents are distributed by CD Rom, DVD Rom or communication link.

vi) Helps in easy document delivery. Users may established their own accounts, change services, pay through credit cards or by some other pre-arranged method and have requested material delivered directly to them by Fax, Email, etc.

3. Advantages of E-Documents

i) Structured Approach: E-document provides accesses to much richer content in a more structured manner i.e. we can easily move from a particular content to a chapter from the index to the original text, etc.

ii) Reference: In case of e-document the endnotes are available by a clickable link from the note of main text. The reference sources provides online link to the original document so a seamlessly integration can be achieved.

iii) Information Retrieval: The user is able to use any search term belonging to the word or phrase of the entire publication. Some online e-document also provides internal search engines.

iv) Updated Information: Latest information can be accumulated in e-document very effectively so a new edition / version can be brought with a little extra cost.

v) Multiple Accesses: The same e-document can be used at the same time by a number of users.

vi) On demand publishing: The individual subscribers can be provided with only that document which match their profile and can be changed accordingly.

vii) Space: E-document requires very little physical space to keep them. So when a library had no space for extension digitization is the only solution.

viii) Preservation and Conservation: An exact copy of the original can be made any number of times without any degradation in quality.

ix) Cost: E-document is cost effective when we consider its maintenance, additional copy, etc.

x) Speed: In case of e-document time lag between the origin of a document and its use by end user will be greatly decreased. Also the time lag in submission of a reference question in library, referring the user to a particular document, its consultation in the computer screen, editing, composing, printing and forwarding will be greatly reduced.

xi) No physical boundary: The user of e-document need not to go to the library physically. People from all over the world could gain accesses to the same information as long as the internet connection is available.

xii) Round the clock availability: E-document can be accessed at any time, 24 hours a day and 365 days of the year.

xiii) Manageability: E-document can easily be managed by adding bookmark and personal notes to the site or by downloading it to private files or database for copying and editing.

4. Disadvantages of E-document: 

The computer viruses, lack of standardization for digitized information, quick degrading properties of digitized material, different display standard of digital product and its associated problem, health hazard nature of the radiation from monitor, etc some of the problem associated with e-document. Some other disadvantages of e-documents are

i) Copyright: E-document will violate copyright laws as the thought content of one author can be freely transfer by other without his acknowledgement.

ii) Bandwidth: E-document will need high bandwidth for transfer of multimedia resources but the unused bandwidth is decreasing day by day due to its over utilization.

iii) Speed of Access: As more and more computers are connected to the internet its speed of access reasonably decreasing, if new technology will not evolve to solve the problem then in near future internet will be full of error messages.

iv) Incompatible Hardware and Software: Due to the absence of common standard regarding hardware and software the display of e-document creates another problem.

v) Initial cost is height: The infrastructure required to access the e-document is generally high i.e. cost of hardware, software, lease line connection, internet LAN, etc.

vi) Preservation: The technology used by a particular e-document publisher becomes out of date very soon due to the rapid technological development. So the data may become inaccessible.

vii) Environment: An E- document cannot be read without the computer system or special equipment needed to access the document. So a user cannot take out an E- document with him to read it at convenient time and place. Again, many people find reading printed material to be easier than reading material on computer screen. So E- document cannot reduce the environment of a traditional book.

            According to Crawford and Gorman (1995), paper and printed still work best for sustained reading while electronic distribution of information is better for communicating data and small packet of information.

viii) Simultaneous Access: Over the world could gain access to the same information as long as the Internet connection is available.

ix) Round the clock availability: E- document can be accessed at any time, 24 hours a day and 365 days in a year.

x) Manageability: E- document can be easily managed by adding book mark and personal notes to the site or by downloading it to private files or database for copying and editing.

Development : Process of differentiation of activity (ies). 

Disintermediation : Relates to the role of the intermediary in acting between information (and other products) and its end-users. In other words, it is the finding of the information by an end-user without the need of a third party. As applied to libraries, disintermediation means the diversion of information from centralized physical repositories to alternate sources available directly through computers and computer networks. 

End-user Empowerment: Refers to end-users having access to information and having the necessary skills to retrieve their own information according to their own needs – in other words, they can do it on their own. With empowerment, they should be less dependent on information specialists. 

Era : Period of history. 

Evolution : Process of organization by development. 

Growth Pattern : Process of increase in size and number with some consistency.

Information Broker : An individual of a firm, who, on demand, seeks to answer questions using all available sources and who is in business for profit.

Information Filter : An essential mediator between information sources and their users. Information 

Institution: An institution which normally performs the activity (ies) related to the knowledge / information transfer. 

Information Manager : Network consists of a group of information managers Network each of whom is assigned information responsibility for a specific technical division while remaining organisationally linked. 

Information Transfer : A chain of activities, the main link being information generator, editor, publisher of primary publications, indexing and abstracting journal producers, libraries, documentation and information centers, on-line services, information companies and the end user. 

Intelligent Agents : Sometimes called bots (and information industry and Push Services know bots) are persons who assist user in document access and delivery. These agents take query from a user and act on his/ her behalf to find a solution. They form the part of the portals infrastructure. Typical example is the Shopping bot. 

Invisible College : An elite of high performing scientists who has an informal network of scientific communication and the published literature. 

Knowledge Mediators : Persons or libraries who provide users with insight into the existing body of knowledge and assist them in acquiring resources referring to or containing such knowledge. 

Technological : Expert both internal and external communication star, Gatekeeper having much higher incidence of exposure to the professional literature, attends more conferences and has more professional affiliations.
