What do you think? How does technology affect human relationships?

In today's modern living, how important is information technology?

A protocol using sliding window starts sending packets to a receiver. SWS = RWS = 10. Sender must send 25 unique packets to the receiver and 15 sequence numbers are available (0-14). During transmission ACKs of 8th,9th and 10th packet are lost.Will the transmission end normally or there will be errors during the transmission?

CAT-6 twisted pair cable is a commonly used computer networks cable that provides a frequency bandwidth of up to 250 MHz. It is suitable for most varieties of Ethernet over twisted pair up to 1000 BASE-T (Gigabit Ethernet). Determine whether a signal-to-noise ratio (SNR) of 20 dB is adequate to transmit 0.9 Gbps on this cable?

A network administrator is connecting hosts A and B directly through their Ethernet interfaces, as shown in Figure 1. a. What kind of a network is this? (1 Mark) b. Ping attempts between the hosts are unsuccessful. What are the two possible solutions for proper connectivity between the hosts? (2 Marks) Figure 1

Using an example, illustrate how checksum is used in error correction and detection. 

Using a diagram, illustrate and explain how twisted pair reduces signal interference
