NETWORKS

Question 1

AWS (amazon, web, service)

Answer 1

Web application platform

Built in infrastructure that’s proven and used by big companies such as:
Sisco & Equinox

Has the server support for scalability and load balancing

High Cache memory and low Latency so our network won’t slow down when a lot of users are utilizing it.

Traffic sent and received will be encrypted. Secure.

Question 2

Disturbed Machine Learning

Answer 2

Allows us to increase our productivity by being able to run our training models over several different devices through (GPU).

More efficient, less error and better results.

Also has the capability to train multiple models at the simultaneously due to using multiple GPU at the same time.

Question 3

Grpc (remote, procedure, call)

Answer 3

Allows us to send information to multiple servers efficiently.

We can send request within any environment (remotely) with the same speed & efficiency it would be if we were next to our server.

Allows us to connect mobile devices to web browsers.

Used by:
Netflix, Spotify, Square, Cisco

Question 4

React Native

Answer 4

Allows us to use javascript to build an app for both android & ios.

We don’t need to use (android) or (ios) specific programs.

It reacts to either API’s.

High productivity (when you edit your code you can see the changes in real time).

Example Apps built on React Native:
facebook, instagram & uber eats -

Question 5

GPU (graphic, processing, unit)

Answer 5

High speed graphic processor

We run GPU for machine learning, which allows us to process more data simultaneously.

Question 6

Database

Answer 6

Storing, maintaining and accessing any sort of data/information.

Question 7

Server

Answer 7

A computer program/device that provides information / services to another computer program / device to its user/client.

Question 8

Cache

Answer 8

High speed memory used to retrieve data efficiently.

Question 9

Load Balancers

Answer 9

Allows the traffic from the user to go to one of many servers that has minimal traffic.

Question 10

Latency

Answer 10

is the delay between a client request and a cloud service provider’s response.

Latency greatly affects how usable and enjoyable devices and communications are.

Question 11

Nodes

Answer 11

A data structure where one point links to another.

Used for Matrix (comparing a list of items within your project through row, column)

Question 12

SQL (structured, query, language)

Answer 12

Database language that allows us to retrieve and manage data within a database.

Used for relational database.

Question 13

Relational Database

Answer 13

Data stored in one or more tables of columns and rows,

Question 14

Database Schema

Answer 14

Defines how data is organized within a relational database;

Example:
table names,
fields,
procedures
data types, and the relationships between these entities.

Question 15

Three Types of Database Schema

Answer 15

1. Conceptual
   2 Logical
2. Physical

Question 16

Conceptional Schema

Answer 16

Big picture view of what the database and it will contain within it.

Question 17

Logical Schema

Answer 17

Information and rules within the database

Example:
table names
entity relationship

Question 18

Physical Schema

Answer 18

Technical information such as the “syntax” that is used to create the schema.
