Designing a Bank Network

INTRODUCTION

In the old days, business was done using papers and flat registers. The organization of these registers was difficult and the storage of huge amounts of data was a real problem. Also, the process of preparing a report takes a lot of time. But when computers were introduced into the business field, everything had changed. Databases were used to store huge amounts of data and organize them. Instead of spending many hours (or maybe days) preparing a report, a query consisting of a number of statements can perform the job in some seconds.
Although databases were very useful, another problem has appeared. Companies and corporations spread over wide distances. A single company can have branches in all the governorates of a country and maybe with some branches outside that country. Data communicating and sharing was a problem. This problem was solved using computer networks which are the best way for data communicating. Nowadays, computer networks are essential for any business. Computer networks are used for file transfer, voice and video conferencing. For this reason, we have chosen our final project to discuss networks from different sides.
In our project, we have selected a network of the Shamil Bank of Yemen and Bahrain to study. Banks are deeply using computer networks to transfer data between the different bank branches. These networks should be designed to be as good as possible to achieve the best performance. Security should also be maintained to prevent from any attack coming from outside or inside the network of the bank.
Our project will consist of two parts. Part one will start by explaining a number of topics that should be understood in order to redesign the network to achieve the recommendations. Due to the idea of part one, it is divided into three chapters. Chapter one will study the network devices that will be used in the project. Chapter two will explain the wireless networks in detail. Chapter four is about network security.
