Short Message Service (SMS) is one of the most popularly used services for communication between mobile phone users. Nowadays, different Instant Messaging (IM) apps such as messenger, WhatsApp, IMO, WeChat, etc., are becoming more and more popular. SMS communication has a general appeal, especially to the youth, because of its flexible use of alphanumeric characters, with little or no regard for orthographical and grammatical rules. However, this flexibility and freedom pose challenges for translating SMS into formal writing. To overcome this, a pre-processing step known as normalization is required. SMS language has, however, been recognized and accepted as a variant of natural language. Thus, there is compelling motivation to make it possible to build information-based services using SMS communication by normalizing the various forms in which the language appears. Therefore, we aim to find a suitable technique for conveniently normalizing the SMS.

Network security is the process of taking physical and software preventative measures to protect the underlying networking infrastructure from unauthorized access, misuse, malfunction, modification, destruction, or improper disclosure, thereby creating a secure platform for computers, users, and programs to perform their permitted critical functions within a secure environment. A local area network (LAN) is a computer network within a small geographical area such as a home, school, computer laboratory, office building or group of buildings. A LAN is composed of inter-connected workstations and personal computers which are each capable of accessing and sharing data and devices, such as printers, scanners and data storage devices, anywhere on the LAN. LANs are characterized by higher communication and data transfer rates and the lack of any need for leased communication lines. A data network is an interconnected system of computers, peripherals and software over which data files and messages are sent and received. LAN is only one type of computer network. LAN define is Data com system allowing a number of independent devices to communicate directly with each other, within a moderately sized geographic area over a physical communications channel of moderate data rates. Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of infrared light through an optical fiber. The light is a form of carrier wave that is modulated to carry information. Fiber is preferred over electrical cabling when high bandwidth, long distance, or immunity to electromagnetic interference is required. This type of communication can transmit voice, video, and telemetry through local area networks or across long distances. Optical fiber is used by many telecommunications companies to transmit telephone signals, Internet communication, and cable television signals. Researchers at Bell Labs have reached a record bandwidth distance product of over 100 petabit × kilometers per second using fiber optic communication. Communication between remote parties can be achieved through a process called Networking, involving the connection of computers, media and networking devices. When we talk about networks, we need to keep in mind three concepts, distributed processing, network criteria and network structure. The purpose of this Network is to design a Local Area Network (LAN) for a BAEC (Bangladesh Atomic Energy Commission) Head Quarter and implement security measures to protect network resources and system services. To do so, we will deal with the physical and logical design of a LAN. The goal of this Network is to examine of the Local Area Network set up for a BAEC HQ and build a secure LAN system.

A high-quality and correctly dimensioned network infrastructure is essential for all well-functional IT systems. An optical fiber-based network can ensure high speed as well as a high-quality network. To fulfill the current requirements of AERE (Atomic Energy Research Establishment), considering its smooth operation of high-speed internet service, the optical fiber-based network is the state-of-the-art network solution. An optical fiber network design refers to the specialized processes leading to a successful installation and operation of a fiber-optic network which includes determining the type of communication system(s) which will carry over the network, the geographic layout, the transmission equipment required, and the fiber network over which it will operate [1].
