Securing Local Area Network

The diagram above shows what a safe home network could look like. In incorporates a number of different hardware and software solutions that work together to help keep the computer systems safe. Step 1:-Install a Hardware Firewall/Router:The hardware firewall/router is at the core of your system security. It is on the “front lines” when it comes to protecting your systems. It’s main security purpose is to let you get out to the Internet while...

Installation of shared folders in the network

The File and Printer Sharing for Microsoft Networks component allows computers on a network to access resources on other computers using a Microsoft network. This component is installed and enabled by default. It is enabled per connection using TCP/IP and is necessary to share local folders. The File and Printer Sharing for Microsoft Networks component is the equivalent of the Server service in Windows NT 4....

The fundamental of network operating system

An Operating System is a collection of programs that provides an interface between application programs and the computer system (hardware). Its primary function is to provide application programmers with an abstraction of the system resources, such as memory, input-output and processor, which enhances the convenience, efficiency and correctness of their us...

Network protocol

A protocol is a set of rules that governs the communications between computers on a network. In order for two computers to talk to each other, they must be speaking the same language. Many different types of network protocols and standards are required to ensure that your computer (no matter which operating system, network card, or application you are using) can communicate with another computer located on the next desk or half-way around the world. The OSI (Open Systems Interconnection) Reference Model defines seven layers of networking protocols....

Network Interface Card

A network card (also called a Network Adapter or Network Interface Card, or NIC for short) acts as the interface between a computer and a network cable. The purpose of the network card is to prepare, send, and control data on the network. ...

Types of Network Interface Cards

Network interface cards, referred to as NICs, are PC integrate cards that give inter-networking capabilities for a particular computing solution. There are many types of NICs that are utilized in changeable situations. The biggest variation between cards is depending upon their connective medium and speed capabilities. To a lesser extent, NICs can be distinguished by their type of connectivity to P...

OSI Reference Model

The Open System Interconnect (OSI) reference model is a model, developed by the International Standards Organization (ISO), which describes how data from an application on one computer can be transferred to an application on another computer. The OSI reference model consists of seven conceptual layers which each specify different network functions. Each function of a network can be assigned to one, or perhaps a couple of adjacent layers, of these seven layers and is relatively independent of the other layers. This independence means that one...

Types of network

One way to categorize the different types of computer network designs is by their scope or scale. For historical reasons, the networking industry refers to nearly every type of design as some kind of area network. Common examples of area network types are:...

Fundamental of networking

Making devices talk to each other for the purposes of communication is nothing new. Early forays into telephony such as the telegraph and telephone have since evolved into more complicated devices, and now a computer can be networked to the Internet, another PC, or even a home stereo. In the early 1960s, individual computers had to be physically shared, making the sharing of data and other information difficult. Seeing this was impractical, researchers developed a way to “connect” the computers  so they could share their resources more...
