NETWORK BASIC

*PEER-to-PEER NETWORK

•  a simple expeensive network that typically CONNECTS FEWER THAN 10 COMPUTERS 
• each computer ,called a PEER , has equal responsibility and capabilities
• sharing hardware (such as printer),data or infomation with other computers on the peer-to-peer nerwork
• each computer stores files on its own storage devices .Thus ,each computer on the network contains both the server operating system and application software 
• all computers on the network share any peripheral device(s) attached to any computer
• peer-to-peer networks are ideal for very small businesses and home users
• some operating system,such as Windows , include a per-to-peer networking utility that allows users to set up a peer-to-peer network
• peers are both suppliers and consumer of resources
• each node is a computer on the network which acts and communications with other  Peer to make a portion of their resourcers such as processing power,disk storage or network bandwith 

directly avaible to other network participants,without need for central coordination by servers or stable hoots 

    *CLIENT/SERVER NETWORK

• client =computer request resources from the server
• server = a computer provides resources to clients 
• server,sometimes called a host computer , control a ccesss to the hardware,software and other resources on the network and provides a centralized storage area for programs ,data and information 
• the clients are other computers and mobile devices on the network that rely on the server for its resources 
• for example: a server might store a databasse of customers . clients on the network (company employees) access the customers database on the server
• client/server architecture works when the client computers sends a resources or process request to the server over the network connection ,which is then processed and delivered to the client
• a sever manage several clients simultaneously whereas one lient can be connected to several servers at a time ,each providing a different set of services 

NETWORK TOPOLOGY

NETWORK TOPOLOGY IS JUST LIKE AN AWKWARD NAME BUT ITS OKEY . NETWORK TOPOLOGY IS REFERS TO THE LAYOUT OF THE COMPUTERS AND DEVICES IN A COMUNICATION NETWORK..
