A processor is the logic circuitry that responds to and processes the basic instructions that drive a computer.

The term processor has generally replaced the term central processing unit (CPU) that has been used in early generations of computers. The processor in a personal computer or embedded in small devices is often called a microprocessor.



Pathping is a TCP/IP based utility that provides useful information about network latency and network loss at intermediate hops between a source address and a destination address.

It is a Windows based command-line tool is similar to the tracert tool in a sense that it traces the path that an Internet Protocol (IP) packet takes from a source to its destination.


Time to Live (TTL)

Time-to-Live (TTL) is a value in an Internet Protocol (IP) packet that tells a network router whether or not the packet has been in the network too long and should be discarded.

In other words, it specifies the number of router hops the packet is yet allowed to travel before it must be discarded or returned.
