data at the same time. Needs to be close to phone company switching station, limited choice of service
providers, supports only a single user.
Cable modem : Fast, always on, most popular broadband type of connection, can support many users;
downloads faster than DSL, users can talk on phone and transmit data at the same time.Slower service during
high traffic times, vulnerability to outside intrusion, limited choice of service providers, not always available to
businesses.
9. Briefly explain what TCP/IP does.
Protocol that enables all computers to use data transmitted on the internet by determining (1) the type of error
checking to be used, (2) the data compression method,if any, (3) how the sending device will indicate that it
has finished sending a message, and (4) how the receiving device will indicate that it has received a message.
TCP/IP breaks data into packets, which are the largest blocks of data that can be sent across the internet
(less than 1,500 characters, or 128kilobytes). IP is used to send the packets across to their final destination,
and TCP is used to reassemble the packets in the correct order

and a static IP address?

user.
Static IP address is a fixed IP address reserved and assigned to a given computer or user for all its internet
sessions. The static IP address , when assigned to a given computer/user cannot be reassigned to another
computer/user .
