Give all possible derivatives of the following words. Use dictionary if necessary.

6. Write the expansions of the following abbreviations and learn them:

VLAN, Telnet, VTP.

1. Source ─ a point where a transmitted ..... enters a network.

2. VLAN ─ a local area network consisting of groups of hosts that are on physically different ….. but that communicate as though they were on the same wire.

3. Broadcast domain ─ a ….. (or part of a network) that receives a broadcast packet from any node located within the network.

4. Monitoring software ─ a program or set of programs used to oversee networks for the purpose of tracking ….. or identifying, reporting on, and solving problems at the earliest possible stage.

5. Access list ─ a table that contains information about which users or groups have ….. to access the network.

6. Trunking ─ a technique for combining two or more Ethernet connections into one logical ….., or trunk, between two devices. It is used to increase the bandwidth capacity of connections and to make these connections more resilient.

7. Algorithm ─ a finite ….. of steps for solving a logical or mathematical problem or performing a task.

8. Assignment ─ the process of setting a variable equal to a ….. or string or character.

8. Translate the passages in writing:

a) The fundamental difference between a router and a Layer 3 switch is that Layer 3 switches have optimized hardware to pass data as fast as Layer 2 switches, yet they make decisions on how to transmit traffic at Layer 3, just like a router. Within the LAN environment, a Layer 3 switch is usually faster than a router because it is built on switching hardware.

b) As networks have grown in size and complexity, many companies have turned to virtual local area networks (VLANs) to provide some way of structuring this growth logically. Basically, a VLAN is a collection of nodes that are grouped together in a single broadcast domain that is based on something other than physical location.

c) While you can have more than one VLAN on a switch, they cannot communicate directly with one another on that switch. If they could, it would defeat the purpose of having a VLAN, which is to isolate a part of the network. Communication between VLANs requires the use of a router.
