Chapter 1: Intro to Networks Flashcards
What’s the formula to determine the amount of connections you’ll need to accommodate your network? pg. 16
n (n-1)/2
How many connections is needed for 20 computers? pg. 16
20 (20-1)/2
20(19)/2
380/2
190 connections
Having a mesh topology will most likely prevent a __ from happening. pg. 16
collision; data from two hosts trying to communicate simultaneously “collies” and gets lost
Although it’s rarely used now, but offers the best fault tolerance, what’s this topology? pg. 16
Mesh
This topology gives you a direct connection between two devices providing a single communication path. pg. 16
point-to-point
What’s the difference on a point-to-point topology to be linked via serial cable or via circuit on an MPLS network? pg. 16
serial cable is a physical network whereas connection via circuit makes it a logical network
The main post office along with it’s multi-branches spread across town would be considered what type of topology? pg. 17
point-to-multipoint
What topology type would be multiple computers assigned to a single hub? pg. 18
Hybrid because it’s a physically (hardware) star topology and a logically (software) bus topology setup
What are the three prime questions to ask yourself when choosing a topology? pg. 19
Finances? Security? Scalable?
What’s the best way to cost-effectively design and setup a few computers in the same room? pg. 20
wireless access point and wireless network cards
List the 5 points to remember when you want the right topology for the right network. pg. 20
1) Cost 2) Ease of installation 3) Ease of maintenance 4) Fault-tolerance requirement 5) Security requirement
What provides structure to the network in which all network segments and servers connect to? pg. 20
network backbone
What is regarded as any small section of the network that is indirectly connected to the “backbone” ? pg 20
segment
