UNIT I:
Introduction: History and development of computer networks, Basic Network Architectures: OSI reference
model, TCP/IP reference model, and Networks topologies, types of networks (LAN, MAN, WAN, circuit
switched, packet switched, message switched, extranet, intranet, Internet, wired, wireless).
UNIT II :
Physical layer: Line encoding, block encoding, scrambling, modulation demodulation (both analog and
digital), errors in transmission, multiplexing (FDM, TDM, WDM, OFDM, DSSS), Different types of
transmission media. Data Link Layer services: framing, error control, flow control, medium access control.
Error & Flow control mechanisms: stop and wait, Go back N and selective repeat. MAC protocols: Aloha,
slotted aloha, CSMA, CSMA/CD, CSMA/CA, polling, token passing, scheduling
