Following are the Servers which have been used; 1. Web server. 2. Email server. 3. DNS server. 4. VPN server. Web server A computer, including software package that provides a specific kind of service to client software running on other computers. A Web server is a server-based product that returns files to clients when requested. These files are typically returned in the form of Web pages to a client internet browser. Most of the web servers are built for the java community, and some are open source

of cloud computing services, such as, SaaS, PaaS, IaaS, public clouds, private clouds, and hybrid clouds Examples. They all work similarly but have not only different tools, but varying levels of security for various needs. These differing types of clouds and networks as a service offer off site data storage in a secured location, which in essence frees up space and virtual infrastructure for personal and/or business networks, and devices. There are advantages and disadvantages to cloud computing

1. What business benefits do cloud computing services provide? What problems do they solve? Cloud computing pools computing resources in a virtual environment to provide businesses with efficient storage and computing services (i.e., server time, processing power, network storage, networking, software, etc.), easy connectivity and accessibility across divergent platforms, flexibility, elasticity of computing resources, scalability, reliability, and redundancy—all on a “pay-for-service” model

WAN optimization tools are used mainly in application delivery networks which consist of WAN Optimization Controllers (WOCs) and Application Delivery Controllers (ADCs). On the data center end Application Delivery Controllers are present to distribute the traffic among servers based on application specific criteria. In the branch office portion of Application Delivery Controllers, WDC are present that uses its advanced compression and flow optimization capabilities to provide application availability

communication has become more easier than ever from email to social media. Many people rely on social networks to keep in contact with friends and family. One of the most popular networks is Facebook. It gives people an opportunity to reconnect with others and post updates or add photos so that people could know what is going on. There are a lot of benefits in using Facebook its one of the the most used social networks. People could send messages you have the choice to send the message as an open manner or to

research to support your answer. The Physical layer is something simple like wiring, fiber and network cards. Devices that allow communication between the OSI networks. Data link layer is the Ethernet, among other protocols; we're keeping this simple remember. The most important take-away from layer 2 is that you should understand what a bridge is. Switches, as they're called nowadays, are bridges. Network layer is an IP address because you're dealing with layer 3 and "packets" instead of layer 2's

the abstraction for supporting the notion of shared memory in a physically non-shared (distributed) architecture. Issues to be addressed in the design and implementation of DSM include maintaining the consistency of the shared data across the network without incurring high overhead and integrating the DSM mechanisms with the local memory management. The consistency model provided by a given DSM implementation attempts to balance performance and ease of programming: while DSM provides the abstraction

denote networks in diagrams of computing and communications systems. The word cloud is used as a metaphor for the Internet, based on the standardized use of a cloud-like shape to denote a network on telephony schematics and later to depict the Internet in computer network diagrams as an abstraction of the underlying infrastructure it represents. In the 1990s, telecommunications companies who previously offered primarily dedicated point-to-point data circuits, began offering virtual private network

4G DEFINITION 4G 3G 2G 1G 0G Fourth Generation Cellular Communication (4G) 4G is not one defined technology or standard, but rather a collection of technologies and protocols aimed at creating fully packet-switched networks optimized for data. 4G networks are projected to provide speeds of 100 Mbps while moving and 1 Gbps while stationary. EVOLUTION OF DATA STANDARDS 4G 3G 2G 1G 0G Zero Generation Mobile Systems (0G) The radio telephone system preceded modern cellular

communications protocols that are used everywhere in analog and digital communications. Computer networks cannot exist without them. With KFF, being that the Home Office or Headquarters is located in La Jolla, there is a T3 dedicated line that connects HQ with Del Mar and Encinitas locations. These lines are usually rented at a monthly or yearly rate to connect geographically separate offices for private voice and or data networking. It is also very costly averaging over $3000 USD per month, so most
