1

Software that takes the incoming data received by the network card, keeps it organized, sends it to the app that needs it, and then takes outgoing data from the app and hands it to the NIC to be sent out over the network

Network Protocol Software

2

Group of simple protocols

Protocol Stack/Suite

3

The primary protocol of most modern networks, including the Internet

Transmission Control Protocol/Internet Protocol (TCP/IP)

4

Identifies the node and the network on which it resides in a TCP/IP network. Unique identification number for your system on the network

IP Address

5

Internet standard protocol that provides a common layer over dissimilar networks; used to move packets among host computers and through gateways if necessary. Part of the TCP/IP protocol suite. Uses the dotted-decimal format - x.x.x.x. Where each x represents an 8-bit binary number (0-255)

Internet Protocol version 4 (IPv4)

6

Portion of the IP address that identifies the network

Network ID

7

Portion of the IP address that identifies the local computer

Host ID

8

A value used by the NIC to distinguish which part of the IP address identifies the network ID and which part of the address identifies the host. It blocks out/masks the network portion of an IP address

Subnet Mask

9

Every computer on a single LAN must have _____ network ID and a ______ host ID

Same, seprare

10

When two computers have the same IP address, they won’t be able to talk to each other and other computers won’t know where to send data

IP Conflict

11

In a TCP/IP network, the nearest router to a particular host. This router’s IP address is part of the necessary TCP/IP configuration for communicating with multiple networks using IP

Default Gateway

12

TCP/IP name resolution system that translates a host name into an IP address. Uses UDP port 53

Domain Name Services (DNS)

13

Special computers that keep databases of IP addresses and their corresponding names

DNS Servers

14

.com, .edu, .mil, .int, .org, .gov, and .net

Top-Level Domains (TLDs)

15

General business domain

.com

16

Educational organization domain

.edu

17

Military organization domain

.mil

18

International domain

.int

19

Nonprofit organization domain

.org

20

Government organization domain

.gov

21

Internet organization domain

.net

22

Protocol that enables client hosts to request and receive TCP/IP settings automatically from an appropriately configured server. Uses UDP ports 67 and 68

Dynamic Host Control Protocol (DHCP)

23

Manually set IP address that will not change

Static IP address

24

Connection-oriented protocol used with TCP/IP. Gets an app’s data from one machine to another reliably and completely

Transmission Control Protocol (TCP)

25

Connectionless protocol used with TCP/IP. Works best when you have a lot of data to send that doesn’t need to be perfect or when the systems are so close to each other that the chances of a problem occurring are too small to bother worrying about. Faster than TCP

User Datagram Protocol (UDP)

26

Services such as HTTP or SSH that run atop TCP/IP

TCP/IP Services

27

Extremely fast protocol used for network file transfers in the WWW environment. Uses port 80

Hypertext Transfer Protocol (HTTP)

28

Terminal emulation program similar to Telnet, except that the entire connection is encrypted

Secure Shell (SSH)

29

Provides a really great way to see if you can talk to another system

“ping” command

30

Windows offers this command-line tool for a quick glance at your network settings

“ipconfig” command
