What is ripcord in unshielded twisted pair cable?
Typically a nylon cord within the sheath of the cable. It is designed to make it easier to remove the outer sheath by tearing through it.
Inside some UTP cable jackets is a polyester or nylon string called the rip cord, also known as the slitting cordor slitting string. The purpose of this cord is to assist with slicing the jacket open when more than an inch of two of jacket needs to be removed. Some cable installers love them; many find them a nuisance, as they get in the way during termination.

The network command 'ping' issues a series of standard, small messages to the destination network address specified by the user. For example:
ping 192.168.0.1
This command will send a number of 'ping' messages to the computer on the network with IP address 192.168.0.1
Upon receiving these messages, the destination machine will echo the same message back to the sender. This is used as a simple check of the network connectivity between the two computers on the network. Since an unreachable address will result in no message being returned, the sending machine must know how long to wait before considering the message lost. This time is known as the 'timeout'.
By default, it is 1000 millisecond (1 second) but it can be set to any time by the user with the '-w' option. For example:
ping -w 2000 192.168.0.1
This will cause the ping program to wait for two seconds before considering a ping packet lost.
