Feasibility Study And Operational Feasibility Computer Science Essay

Published:

This essay has been submitted by a student. This is not an example of the work written by our professional essay writers.

A non-profit organization has established a village primary school for a long time. The teachers still present their material to the pupils on the traditional whiteboard with the markers.

And the policy of the school is not allowed to dispose the old records about the students. So many documents have been accumulated in the school. No more space for the new coming document. They may be moved to the outside warehouse with the rental fee.

The senior management of the school is going to change the existing education style and also need to computerize the administration for the school and to handle the document as the electronic media.

Therefore they apply the government funding for establishing a computer network.

I am working in the non-profit organization for the project management and the senior management of the village school request me to handle the project.

Assumption:

I act as the Project Manager in charge of the project. A Project Engineer implements the tasks under my monitoring and instruction

There is no any existing computers and network in the village school.

The teachers in the village school have only the basic knowledge to use the computers and the software such as Windows operation system and MS Words, Excel and PowerPoint.

The length of the LAN cable from the network backbone of the computer room to each node of the staffs room, teacher room and classrooms is NOT over the length of 100 meters.

A dedicated room (named as Computer Room) is assigned to keep the important network devices, server(s) and 6 computers for the computer study / practice to the pupils. The network printer also is required to be set up there.

The location of the village school is available to the ISP companies to provide the Internet Connection Service.

The cost the whiteboard markers is about HKD 6,000 per year. And the annual rental fee of the outside warehouse is HKD 24,000.

8> The amount of the government funding is up to HKD180,000.

Task 1

1.1 Feasibility Study

1.1.1 Description of requirement

Within 6 months to set up the computer and network system in a small village primary school.

The system requires the below items:

8 desktop computers with Internet connection,

2 interactive whiteboards for classroom use,

1 networked laser printer and,

WebSAMS application software for school administration.

The domain name application and the network configuration for WebSAMS.

The system allows the pupils to:

a) access the Internet for research purposes, and for learning materials.

b) prepare written assignments and print them out

The system allows the teaching staff to:

a) keep records of student attendance at classes and marks for tests, exams and assignments.

b) access the Internet for teaching materials that can be used on the interactive whiteboards.

The additional requirement:

In each classroom, a cabinet should be made to keep and to protect the computer, the projector and the device for IWB against the naughty behavior from the pupils. The cabinet should be movable for the distance adjustment between the whiteboard and the projector.

1.1.2 Technical factors

In the market, we can find the system for 32 bits and 64 bits. And the 32bits system is running for a long time and become very mature and stable. Therefore we decide to use the 32bits system for the project.

1.1.2.1 The main hardware involved in the project:

Server Computer:

Option 1: Tower server

(Figure: 1)

A tower server (Figure: 1) built in an upright cabinet that stands alone.

Advantages:

Easier cooling, because the overall component density is fairly low.

Scalability, because an unlimited number of servers can be added to an existing network

Disadvantages:

A set of tower servers is bulkier and heavier than an equivalent blade server or set of rack servers.

Cabling for a large set of tower servers can be complicated.

A group of several air-cooled tower servers in a single location can be noisy because each tower requires a dedicated fan.

Option 2: Rack server or Blade server

(Figure: 2a) (Figure: 2b)

A rack server (Figure: 2a) or a rack-mounted server is designed to be installed in a rack. The rack (Figure: 2b) contains multiple mounting slots called bays,

Advantages:

A single rack can contain more servers stacked one above the other, minimizing the required floor space and consolidating the network resources.

The rack server configuration also simplifies cabling among network components

The movable server rack has got the rolling wheels. It is convenient if the server(s) need to be moved to another location.

Disadvantage:

The special cooling system is required to prevent excessive heat buildup when many power-dissipating components are located in a small space

The additional cost is required for the rack.

Recommendation for server computer:

The tower server (option 1) is recommended.

The cost of the tower server is economic than the rack server under the similar specification. No server rack is required.

The number of server will not be expanded too much in the future.

The computer room is isolated. Other people will not be disturbed by the noise from the cooling fans of the server(s).

Suggested item:

IBM System x3400 M2

(The specification is mentioned in Task 3)

Client Computer (Workstation):

We will not consider the portable computers such as notebook computers or net book computers because the requirement of the workstations is the desktop computers.

Suggested item:

Lenovo ThinkCentre A58 Tower

(The specification is mentioned in Task 3)

It also bundle the Windows 7 Professional.

Network Printer

Option 1: Monochrome laser printer

Option 2: Inkjet color printer

Recommendation for network printer:

The inkjet color printer (option 2) is recommended.

Base on the consideration of the cost, the color laser printer will not be chosen in the project. The printing speed and printing quality are the main causes of consideration. Therefore the inkjet printer is preferred.

Suggested item:

Brother MFC-5890CN

It also provides the scanning and FAX service for the document.

(The specification is mentioned in Task 3)

Interactive Whiteboard (IWB)

Option 1: Resistive touch-based IWB

(Figure: 3)

A membrane (plastic feel) is over the surface that is deforms under pressure by a human finger or the simple pointing device to contact the conducting backplate. The location of the touching point can be determined electronically as a mouse event.

Advantages:

It is easy and natural to use.

There is no dependent to the specific pen or pointing device.

Disadvantages:

The higher cost of the device.

The aging of the membrane will affect the sensitivity and responsibility of the IWB.

Option 2: Electromagnetic pen-based IWB

(Figure: 4)

The location of the stylus of the pen is determined by the wires which are embedded behind the surface of the board that interacts with a coil in the specific pen. The mouse pointer will track it when the pen is near the surface of the board. To press the pen tip on the board will activate a switch in the pen as the mouse click to the computer

Advantage:

It is more accurate at emulating a mouse.

As the natural pen action when the user leans on the board while writing.

It is possible to offer multiple input using multiple pens.

Disadvantage:

The higher cost of the device.

The specific pen is required.

Option 3: Portable Ultrasonic, Electronic Pen-based IWB

(Figure: 5)

The user can control the computer after the calibration of the projected image by the electronic pen. The scanning area of the device is up to 3m by 1.5m (about 110" interactive whiteboard.)

Advantage:

It can be more portable than the option 1 and 2.

No need any signal receiver device to be attached onto the projection screen/surface.

The traditional whiteboard or the wall surface can be used as the screen.

The device has got the small size and light weight. It is convenient to carry it to anywhere.

Disadvantage:

The specific pen is required.

Option 4: Wiimote, IR pen-based IWB

(Figure: 6)

Using the Wii remote control and the IR camera to track dots of an Infra-red light.

Advantage:

It can be more portable than the option 1 and 2.

No need any signal receiver device to be attached onto the projection screen/surface.

The traditional whiteboard or the wall surface can be used as the screen.

The device has got the small size and light weight. It is convenient to carry it to anywhere. It is possible to mount the device on the ceiling.

Disadvantage:

The hand or body will block the light path between the camera and the pen then cause pen(writing) data to be lost.

Recommendation for IWB:

The portable ultrasonic, IR pen-based IWB (option 3) and Wiimote / IR based IWB (option 4) can be considered.

We don't consider option 1 and 2 because:

1) the cost is more higher.

2) The product size is big and it may be located in the classroom without any protection. It is easy to be damaged by the pupils when the teachers leave the classroom.

3) It is not convenient to the operation if you lock the product in the store room after use and then move it back to the classroom for the next lesson.

USD 3,000 per processor (USD 2,900 without Hyper-V)

Recommendation for server OS:

MS Windows Server 2008 Standard Edition (option 2) is recommended.

We don't choose the option 1, 3 and 4 because:

The project mainly needs the server to provide the data storage and the application of the HTTP server. The availability is not requested to a very high level.

The price of Enterprise Edition and Datacenter Edition is higher than Standard Edition.

Moreover, Enterprise Edition has got the failover clustering service which is not necessary in a small village school.

Datacenter Edition, also has got the failover clustering service, is designed for the hosting companies that they need the powerful OS to handle the huge amount of data.

Web Edition is the cheaper one. It is designed for the web server and not supported the Hyper-V virtualization. It is impossible to setup two servers in one physical server computer. Therefore it is not suitable to the project.

Operation System (OS) in client computer:

MS Windows 7

Windows 7 is the major release in the current market after Windows Vista. The core of the operation system is not modified from the previous system(Vista or XP). The program developers rebuild the core as a fresh version.

Windows 7 not only provide the high security level but also the faster booting at startup.

Windows XP mode is necessary for the better compatibility. Therefore we will not use the Home Premium edition.

The Ultimate edition has got the new function (BitLocker) for the data encryption of the hard disk and portable device(e.g. USB memory stick) and the price is just a little higher than the Professional edition.

Suggested item:

It depends on which OEM version that is bundled in the workstation computer.

Normally the MS Windows 7 Professional is bundled.

Software package for data processing

Option 1: MS Office 2007

Microsoft Office 2007, codenamed Office 12, is a productivity suite for Microsoft Windows. It was released to volume license customers on November 30, 2006 and made available to retail customers on January 30, 2007.

Option 2: MS Office 2010

Microsoft Office 2010 is the successor to Microsoft Office 2007.

We consider MS Office 2010 for the better compatibility to the different document types

Anti Virus software

Option 1: Standalone type

The software is running on the computer without any centralized management.

Each computer need download the virus pattern from Internet.

The performance of internet connection is affected when most of client computers download the virus pattern within the same period. Moreover the updating efficiency is low.

Option 2: Network type

A centralized management interface has been provided to the administrator. Only the server-side computer downloads the virus pattern from internet. The client-side computers download the pattern from the server via local network.

Recommendation for anti-virus software:

Network type is recommended.

Suggested item:

Trend Micro Office Scan Corporation Edition

1.1.2.3 The networking safety facilities involved in the project:

Firewall

Option 1: Software firewall

The software firewall is installed in each individual PC. It checks each request from the network to the PC and determine whether the request is valid. It also can be configured to check the outgoing request.

Advantages:

The total cost of the license fee is less than the price of a hardware firewall if the quantity of computer in the local network is small.

Easy configuration than the hardware firewall.

It is portable. Because the software firewall is installed to your notebook that can be effective in other network.

Disadvantages:

More system resource is used and affect the performance and efficiency of the computer.

Software firewall can only close the un-used ports and monitor the traffic to and from the computer. It can not hide the IP address.

Option 2: Hardware firewall

The hardware firewall is connected between the router/modem of wide area network (WAN) and the local area network (LAN).

Advantages:

Hardware firewall does not run in the computer, the performance or operation speed of the computer will not be affected.

The malicious software is not easy to make the hardware firewall disable.

A single hardware firewall can protect the whole local area network.

The expected traffic can be restricted before it get in the local network.

The cost of one hardware firewall may be lower than the total amount of the license charge of the software firewall on each PC in the local area network.

Disadvantages:

Hardware firewall may be difficult to configure.

Hardware firewall usually handle the outgoing traffic from local network as safe. If the client PC has got the virus/spyware and connect to the hazardous web site, the hardware will not stop it.

Recommendation for firewall:

The hardware firewall is recommended.

Moreover the anti-virus software must be installed in each computer.

Suggested item:

ZyXEL firewall - ZyWall 70

(The specification is mentioned in Task 3)

1.1.2.4 Fault Tolerance facilities for server:

Option 1: Storage Area Network (SAN)

(Figure: 7)

SAN is usually for the huge amount data storage system such as the datacenter. If the server provides the high availability with failover clustering, SAN also is used. SAN need the additional and external device for the array of the hard disks to provide the huge storage ability

Option 2: Redundant Array of Inexpensive Disks (RAID)

RAID combines multiple low-cost and less-reliable disk drive to provide the reliability through redundancy

There are many different schemes or architectures for RAID which is named as RAID 0, RAID 1. RAID 5, RAID6, RAID 10 and so on.

Recommendation for Fault Tolerance facilities:

RAID technology is recommended based on the consideration of the cost and the actual need

The RAID 10(mirror + Stripe) is selected for the fault tolerance.

It is a cheaper solution than SAN.

RAID 10 (figure: 8) provides the advantage both of RAID1 (fault tolerance) and RAID0 (high performance).

(Figure: 8)

1.1.3 Operational feasibility

Internet Service Plan

Option 1 : Dynamic IP without Symmetric bandwidth

It is the most cheap service plan for the internet connection service.

There is no fixed IP assigned by the ISP to the user's network. Moreover the bandwidth for upload and download are not the same. Normally the upload speed is lower than the download speed so much.

Option 2 : Static IP with Symmetric bandwidth

Its service charge is expensive than the dynamic IP without symmetric bandwidth.

A single or a group of global IP address is assigned to the user. Moreover the bandwidth of upload and download are the same.

Recommendation for internet service plan:

Static IP with Symmetric bandwidth is recommended.

Suggestion :

10M symmetric bandwidth plan with 4 fixed IP addresses.

Because we need assign the 4 global IP address for the below items:

WebSAMS server

HTTP server for WebSAMS service

NAT service for the internet browsing from the LAN

WAN port of the firewall

Network Scenario

Option 1 : Pure Wired Network

(Figure: 9)

The network devices, server and the network printer are set up at the fixed position in the computer room.

The cable is wired to the classroom from the computer room.

Each classroom has got a switching hub, a desktop computer, a projector and an IWB device that are located in a tailor-made wooden cabinet with wheels for the movement inside the classroom and protection against the pupils' naughty behavior.

Advantages:

The single skill for the installation is applied to pure wired network.

The cost is reduced by the simple infrastructure in the pure wired network.

Disadvantage:

No portable device is allowed in the network.

The movement distance of the movable cabinet is limited by both of the power cord and the LAN cable.

Option 2: Wired and Wireless Network

(Figure: 10)

The configuration in the computer room is the same as the option 1.

In the classroom, the wireless access point is installed instead of the 4 ports switching hub.

The computer in the classroom connects to the network with the wireless signal.

Only the power cord is connected to the computer from the wall socket.

Advantages:

The movement distance of the movable cabinet is limited by the length of the power cord only.

The portable device is allowed in the network.

Disadvantage:

The complex skill for the installation is applied to the combined network.

The cost is increased by the complex infrastructure and the additional configuration for the access security in the wireless network.

Recommendation for network scenario:

Based on the consideration of the cost and the actual situation, the option 1 is recommended.

We estimate that the billing amount will be increased 5,000 per month.

Tangible benefit

Save the cost of the markers and brushes for the whiteboard.

Save the cost of the rental charge for the old document because all of the document can be scanned and saved in the hard disk or DVD.

(Please refer to assumption no. 7 for the above points)

Cost and Benefit analysis

The Cost / Benefit diagram is as below shown:

From the above diagram, the breakeven point will happen in the 12th year.

As the non-profit organization, actually it is not the main point to be concerned. The intangible benefit should be emphasized more.

Intangible factors

Stop to use the whiteboard markers that the volatile ink make the bad smell and cause the potential sensitive disease of throat.

Improve the efficiency of the data searching for the student record.

The pupils feel more interesting in the lesson.

Let the pupils touch more fresh things via the internet.

Rise up the reputation of the village school.
