Computer Networks NETWORKING CONCEPTS Network A network is basically an interconnection of various points to make a connected system e.g Road‚ Telephone‚ Social Data Network A computer network therefore refers to an interconnection of computers and other peripherals by use of a communication link Peer to Peer Networks In a peer-to-peer network‚ all computers are considered equal; they all have the same abilities to use the resources available on the network. Peer-to-peer networks are designed

They will have tablets‚ laptops‚ departmental printers‚ and smart phones. This is also based upon the understanding that every Department will have at least two printers for the staff and one for the Manager/Supervisor or VP of

IP addresses consist of numbers that are 32 bits long (in binary)‚ have 4 octets (bits of 8) and use the decimal dot notation. IP addresses are comprised of two components: the network ID and the host ID. For example: In a class C network: 192.168.10.128 Network ID Host ID (16-bit block) (8-bit block) DNS (domain name system) is used with IP addresses. DNS converts domain names and websites to IP addresses‚ which a computer can read. The computer remembers the IP address
