What is Sonet
Synchronous Optical Network is a fiber optic technology that can transmit high-speed data audio, used for text and video.
Single clock handles timing of transmissions as well as equipment enables predictability and ability to multiplex using TDM. The bandwidth of the fiber is determined as one channel divided into timeslots to define sub channels.
Standard recommendations for equipment is able to handle signals from incompatible tributary systems
Q. Multimode for transmitting optical signals? - Multiple beams from light source travel through core at different paths - Multimode step-index fiber Density remains
ATM designers select cells over packets because of the following facts: Cells are fixed length and memory management for them is easy. Handling variable length packets tends
Question 1 requires you to develop firewall rules based on a fictitious organisation. Scenario: You work for a security-conscious company, xC-Cure, who develop encryption t
To accept its goals, ATM uses fixed, small sized packets known cells. Every cell has 53 octets. VPI/VCI fields shows the cells destination. PRIO say if cell can be discarded CRC
What are the main features of TCP connections? Why is it said that TCP provides full-duplex service?
10BASE-T: This is another standard of wiring function. It is usually known 10Base-T, TP Ethernet or Twisted Pair. It removes AUI cable with twisted pair cable and thick coax
Compare Error Detection and Error Correction: The correction of errors is more difficult than the detection. In error detection, checks only any error has happened. In error co
Question 1 Explain FDM and TDM with example Question 2 Define B-ISDN and explain its services Question 3 What is symmetric key cryptography? Describe one symmetric
A default route is used if there is not a particular entry in the routing table for the destination.
Process to send data is called as encapsulation and process to receive data is called De-encapsulation.
