Flashcards in Network Essentials Deck (26):
1

Network Essentials

Group or system of interconnected people or things.
2 or more connected computers that can share resources.

2

Local Area Network

LAN
Small (Network) Group of interconnected computers.
2 host computers talk in binary code (1 and 0)

3

Router

Connects 2 LANs

4

Common Network Components
-3 Most common?

Workstation
Servers
Host

5

Servers
-5 different servers

Mail Server
Web Server
Application Server
Proxy Server
File Server

6

Mail Server

Networks "post office". Handles email functions

7

Web Server

Manages Web activities by using hypertext transfer protocol (HTTP) for storing web content and accessing web pages

8

Application Server

Manages network applications

9

Proxy Server

Handles tasks in place of other machines on network. Like internet connection

10

File Server

Stores and dispenses files

11

Host

Any network device with an IP Address

12

Wide Area Network

WAN
Bigger than LAN
Usually needs router port(s)
Larger geographic are

13

Internetwork

Type of LAN and/or WAN that connects a bunch of networks or intranets.

14

Centralized

Type of WAN
Composed of a main centrally located computer or location that remote computers and devices can connect to.

15

Multiprotocol Label Switching layout

MPLS
Switching mechanism that imposes label (numbers) to data and then uses those labels to forward data when it arrives at the MPLS network

16

Peer to Peer Network

When it comes to authority, they are all equal

17

Client Server Network

Single Server uses a network operating system for managing the whole network

18

Physical Network topologies
-7

Star
Ring
Mesh
Point to point
Point to multipoint
Hybrid
Bus

19

Ring

Each computer is directly connected in the same network.
Adding another network is a drawback. The ring would break which brings Network down

20

Star

Gives more scalability
If the hub fails, all computers go down.
If a computer fails, only that computer goes down

21

Mesh

Path to every machine to ever other in the network.
Has most physical connections per device

22

Point to point

Direct connection between 2 routers or switches, giving one communication path

23

Point to multipoint

Consist of a succession of connections between an interface on one router and multiple destination routers
Drawback is the hub is the single point of failure

24

Hybrid

Combination of 2 or more types of physical or logical network topologies working together within the same network

25

Bus

Daisy chain
2 distinct and terminated ends. All computers connecting to unbroken cable

26

Network backbone

It divides network into different parts called backbones.
Common connecting point for all segments
