DNS

Answer 9

Domian Name System - Naming system for computers, services, or other resources connected to the internet or a private network. Tranlates readable domain names to IP addresses.

Question 10

VPC

Answer 10

Vitural Private Cloud - An on-demand configurable pool of shared computing resources allocated within a public cloud emviroment, providing a certain level of isolation between different organizations using the resources.

AWS - VPC lets you provision a logically isolated section of the AWS Cloud where you can launch AWS resources in a virtual network that you define. You have complete control over your virtual networking environment, including selection of your own IP address range, creation of subnets, and configuration of route tables and network gateways.

Question 11

Application Protocol

Question 12

HTTP

Answer 12

Hypertext Transfer Protocol - An application for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web, where hypertext documents include hyperlinks to other resources that the user can easily access, for example by a mouse click or by tapping the screen in a web browser.

Question 20

TSP

Answer 20

Tunnel Setup Protocol

Question 21

IPv4

Answer 21

The fourth version of the internet protocal (IP). It is one of the core protocols of standards-based internetworking methods in the Internet and other packet-switched networks.

Question 22

IPv6

Answer 22

IPv6 is the most recent version of the Internet Protocol, the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. IPv6 was developed by the Internet Engineering Task Force (IETF) to deal with the long-anticipated problem of IPv4 address exhaustion. IPv6 is intended to replace IPv4.

Question 23

Internet Protocol

Answer 23

The pricipal commuincations protocol in the internet protocol suite for relaying datagrams acress network boundries. Its routing function enables internetworking, and essentially establishes the Internet.

IP has the task of delivering packets from the source host to the destination host solely based on the IP addresses in the packet headers. For this purpose, IP defines packet structures that encapsulate the data to be delivered. It also defines addressing methods that are used to label the datagram with source and destination information.

Question 24

Datagram

Answer 24

Is a basic transfer unit associated witha packet-swithced network. Datagrams are typically structured in the headerand payload sections.

Question 25

Packet Switching

Answer 25

is a method of grouping data that is transmitted over a digital network into packets. Packets are made of a header and a payload. Data in the header is used by networking hardware to direct the packet to its destination where the payload is extracted and used by application software. Packet switching is the primary basis for data communications in computer networks worldwide.

Question 26

Header

Answer 26

Supplemental data placed at the beginning of a block of data being stored or transmitted. In data transmission,

Question 27

Payload (Body)

Answer 27

Is the part of transmitted data that is the actual intended message.

Question 28

Metadata

Answer 28

Is “data that provides information about other data.” It is “data about data”

Question 29

VLAN

Answer 29

Virtual LAN - Is a broadcast domain that is partitioned and isolated in a computer network.

Question 30

Throughtput

Answer 30

The rate of production or rate at which something is processed.

Question 31

Internet Protocol Suite

Answer 31

he Internet protocol suite is the conceptual model and set of communications protocols used in the Internet and similar computer networks. It is commonly known as TCP/IP because the foundational protocols in the suite are the Transmission Control Protocol and the Internet Protocol.

TCP - Tranmission Control Protocol

SSL/TLS - often runs on top of TCP

Question 32

Bandwidth

Answer 32

The network capacity of data it can transmit.

Question 33

Bandwidth

Latencity

Throughput

Answer 33

Bandwidth - amount od data being transferred

Latency - The amount of time it takes for the transfer

Throughput - The aount of data that is being transferred over a set period of time.
