Hardware Requirements For A School 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 small village school does not have computers. So the government gives funding specifically to buy a network of 8 desktop computers with internet connection, two interactive whiteboards for classroom, a network laser printer and off-shelf database.

Now the school is running without internet connection. So the student has many problems, such as searching their assignment using internet connection. And also the school does not have printers. So the student cannot print their assignment at school. If they have internet connection to study, they will have benefits. But only the disadvantage of the internet connection is expansive.

Now the school does not have computers. So the staff records the student attendance at classes on paper. And they also record the marks of test, exams date, exam time are recorded on paper. And then assignments title, start date and date are recorded on paper. The paper is not good for store because it is easy to get damage e.g. natural disaster. If we can use the computer which has many store space, it can save our data safely. Now they do not have interactive whiteboard. If we can use this interactive whiteboard which have internet connection, it can give benefits for both teachers and students.

As the school has teaching staffs and pupils, we need to buy at least 8 desktop computers. We can buy network accessory devices for local area network and internet connection. The student can also summit their assignments and print them out using these networked computers.

Description of Benefit for proposed system

Teacher

Teaching system

Now a day the teacher teaching Whiteboard. Now a day the technology is very development. So the use of the white board is not suitable for leaning. If the system is finish the teacher are teaching with interactive whiteboard.

File store

Now the teacher is store the student attendance on paper. The paper is easy to damage. If we can forgot where the paper is store, we can lose the student attendance paper. And then they record on paper such as exams- date, time, marks, assignment- Start date, End date, title. It is not suitable for storing. we can change a computer system have many benefits. Because all of the records are store in computer and they can not damage and they can not lose.

Student

Learning

The student is working their assignment on using internet. But the school does not have internet connection. So the student has many problem. If the internet connection is finish we have many benefits. Such as easy to work their assignment, easy to communicate other student and other people.

Waterfall Diagram

We would like to use and choice waterfall model because this model is easy to understand and easy to use. This model has six stages. They are requirements analysis and specification, analysis, design, code and unit test, integration test and system and acceptance test.

Waterfall

Stages of waterfall model

Requirement Analysis & Specification

Requirement Analysis & Specification follow the preliminary survey and feasibility study.

Analysis

Analysis of the current system is linked with the business requirements and to produce the logical requirements to produce the logical required system module and requirements specifications.

Design

Design contains the program specification.

Code & Unit Test

Code & Unit Test the programs are written and full tested.

Integration Test

Integration test are curried out to check that all the programs can run correctly as a completed system.

System & Acceptance Test

System & Acceptance Test are curries out to check that the system runs correctly and does what it supposed to. Acceptance testing is the user responsibility.

The IT computer sale and service center hardware costs is expansive but they give a warranty and all of the protect is new model so the cost of the protect is expansive. We use the computer at small school. So we don't need latest issues. We need normal standard of computer. The IT computer sale and service center software costs is expansive but they give update for software.

The Technology Land computer sale and service hardware cost is cheep but the parts of the computer is old model. And the software costs is cheep. So they cannot give any service for software.

The CDC computer sale and service center hardware costs is normal. And then they give warranty and discount. The model of the computer is suitable for student and teacher. The software cost is normal and they give update for software. So we recommend the CDC computer sale and service center. It is suitable for teacher and student.
