  A star network consists of one central switch, hub or computer, which acts as a conduit to transmit messages. This consists of a central node, to which all other nodes are connected; this central node provides a common connection point for all nodes through a hub. In star topology, every node (computer workstation or any other peripheral) is connected to central node called hub or switch.

• Question 395:

• Question 400:

  Which of the following uses classless subnet masks across a network?

  A. Subnetting
  B. CIDR
  C. Supernetting
  D. Summarization
  B. CIDR

  ---

  Classless Inter-Domain Routing is based on variable-length subnet masking (VLSM), which allows a network to be divided into variously sized subnets, providing the opportunity to size a network more appropriately for local needs and also CIDR allows an address or routing prefix to be written with a suffix indicating the number of bits of the prefix, such as 192.168.2.0/24.
