Cisco intro

Question 1

Peer-to-Peer (P2P) File Sharing

Answer 1

The user joins the P2P network by simply installing the P2P software. P2P file sharing has not been embraced by everyone.

Question 2

SOHO

Answer 2

small office home office

Question 3

Client
Web
File
E-mail

Answer 3

server
firefox
google drive uses firefox
gmail

Question 4

Pro’s of P2P

Answer 4

Easy to set up
Less complexity
Lower cost since network devices and dedicated servers may not be required
Can be used for simple tasks such as transferring files and sharing printers

Question 5

Con’s of P2P

Answer 5

No centralized administration
Not as secure
Not scalable
All devices may act as both clients and servers which can slow their performance

Question 6

End devices

Answer 6

An end device is either the source or destination of a message transmitted over the network, Like a tablet

Question 7

Intermediary Network Devices

Answer 7

Like a router or a switch connect the individual end devices to the network and can connect multiple individual networks to form an internetwork. These intermediary devices provide connectivity and ensure that data flows across the network.

They also regenerate and retransmit data signals
Notify other devices of errors and communication failures
Direct data along alternate pathways when there is a link failure
Classify and direct messages according to priorities
Permit or deny the flow of data, based on security settings

Question 8

Metallic wires within cables

Answer 8

data is encoded into electrical impulses

Question 9

Glass or plastic fibers (fiber optic cable)

Answer 9

data is encoded as pulses of light

Question 10

Wireless transmission

Answer 10

data is encoded using wavelengths from the electromagnetic spectrum

Question 11

Network Media

Answer 11

Wireless media
LAN Media
WAN Media

Question 12

Network Interface Card

Answer 12

A NIC, or LAN adapter, provides the physical connection to the network at the PC or other end device. The media that are connecting the PC to the networking device, plug directly into the NIC (Figure 2).

Question 13

Physical Port

Answer 13

A connector or outlet on a networking device where the media is connected to an end device or another networking device.

Question 14

Interface

Answer 14

Specialized ports on a networking device that connect to individual networks. Because routers are used to interconnect networks, the ports on a router are referred to as network interfaces.

Question 15

Multilayer Switch

Answer 15

Een meerlagige switch is een computernetwerkapparaat dat OSI-laag 2 inschakelt als een gewone netwerkswitch en extra functies biedt op hogere OSI-lagen.

Question 16

Topology diagram

Answer 16

A diagram provides of how devices in a large network are connected.

Question 17

Physical topology diagrams

Answer 17

Identify the physical location of intermediary devices and cable installation.

Question 18

Logical topology diagrams

Answer 18

Identify devices, ports, and addressing scheme.

Question 19

Metro Ethernet

Answer 19

high-speed business class copper or fiber connection

Question 20

SDSL

Answer 20

A symmetric digital subscriber line
business class service that provides the same upload and download speeds over telephone lines

Question 21

WISP

Answer 21

Wireless Internet Service Providers are typically found in rural areas where DSL or cable access is not available. A dish or antenna on the property of the subscriber connects wirelessly to a WISP transmitter, eliminating the need for physical cabling outside the building.

Question 22

Intranet

Answer 22

Connect LANs and WANs that should only be accessible by internal employees, whereas an extranet allows organizations to do business directly with other external organizations by allowing them access to part of the internal network.
