This Concept Map, created with IHMC CmapTools, has information related to: Untitled, NETWORK PEER-TO-PEER AND SERVER A Server is a computer program running to serve the requests of other programs, the "clients". T hus, the "server" performs some computational task on behalf of "clients". The clients either run on the same computer or connect through the network.., TOPOLOGIES Disantages 1.Es más caro 2.si el swith o hub se averia, la red deja de funcionar 3.Se requiere un experto para montar la red, TYPES OF NETWORK LAN It is a network that is confined to a relatively small area. It is generally limited to a geographic area such as a writing lab, school, or building., NETWORK Advantages 1.User access control. 2.Information storing and sharing. 3.Internet. 4.Workgroup Computing. 5.Flexible Access., NETWORK WIRED AND WIRELESS Wireless is the transfer of information between two or more points that are not physically connected. Distances can be short or as far as thousands or even millions of kilometers for deep-space radio communications., NETWORK WIRED AND WIRELESS Wired use Ethernet cables and network adapters. Although two computers can be directly wired to each other using an Ethernet crossover cable, wired LANs generally also require central devices like hubs, switches, or routers to accommodate more computers., TOPOLOGIES Disantages 1. If a cable or a computer breaks the network stops working. 2. Turning off a computer, network stops working too. 3. It's hard to find a fault., NETWORK PEER-TO-PEER AND SERVER PEER-TO-PEER is a distributed application architecture that partitions tasks or workloads among peers. Peers are equally privileged, equipotent participants in the application. They are said to form a peer-to-peer network of nodes.., TOPOLOGIES Advantages 1. If a machine failure, this does not affect others. 2. There are few collisions because each machine has its own cable. 3. It is safer., TOPOLOGIES Disantages 1. If there is a central problem in the cable all the computers fail. 2. If many machines connected everything is going very slow. 3. It can cause data collisions. 4. Limited by the cable. 5. Has little security., NETWORK WHAT IS A NETWORK A network consists of two or more computers that are linked in order to share resources (such as printers and CDs), exchange files, or allow electronic communications. The computers on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams., NETWORK Desventajas 1.Expensive to Install. 2.Requires Administrative Time. 3.Servers have Fails. 4.Cables May Break. 5.Security is bad., TYPES OF NETWORK WAN It is a network in larger geographic areas, such as Florida, the United States, or the world. Dedicated transoceanic cabling or satellite uplinks may be used to connect this type of global network., TOPOLOGIES Advantages 1. The data transfer is simple because it goes in one direction. 2. There is no data collision., TOPOLOGIES Advantages 1. Easy to install. 2. Easy to add computers. 3. Use less wire than a star network.
