Ping sweeps First‚ a ping is a computer network utility tool using the Internet Control Message Protocol (ICMP) to send multiple data packets to a target host device such as server‚ workstation‚ or printer to establish whether that host device on a network is actively present (turned on‚ or active) and able to communicate. If the target host

1 - Flow Control Lab Objective To observe common flow control and error control mechanisms used in networks. You will examine how TCP works in order to demonstrate the method it uses to control the rate of transmission or flow control. All protocols have methods to assure that transmitted information will not overrun the receiver. We will watch the sliding windows form and grow through the process of slow start. Explanation and Background The TCP/IP Protocol Suite has two protocols at the Transport
