Networking in IoT age for big opportunities (1 of 3)

Networking Basics
Networking Basics
In most cases, this connection is made via electrical cables that carry the information in the form of electrical signals. Other types of connections are used, too. 

For example, computers can communicate via fiber optic cables at extremely high speeds by using impulses of light. And in a wireless network, computers communicate by using radio signals. Client computers Server computers Network interface- network port Cable: Computers in a network are usually physically connected to each other using cable Switches: You don't typically use network cable to connect computers directly to each other. Instead, each computer is connected by cable to a central switch, which connects to the rest of the network Wireless networks: In a wireless network, most cables and switches are moot. Radio transmitters and receivers take the place of cables. Of course, the main advantage of wireless networking is its flexibility: no cables to run through walls or ceilings, and client computers located anywhere within range of the network broadcast. Network software: What really makes a network work is software, which has to be set up just right to get a network working 

What is Network: A network is simply two or more computers, connected, so that they can exchange information (such as e-mail messages or documents) or share resources (say, disk storage or printers).

Benefits of network:
- Sharing resources
- Sharing information
- Sharing applications

The best 5 differences of AWS EMR and Hadoop

With Amazon Elastic MapReduce (Amazon EMR) you can analyze and process vast amounts of data. It does this by distributing the computational work across a cluster of virtual servers running in the Amazon cloud. The cluster is managed using an open-source framework called Hadoop.

Amazon EMR has made enhancements to Hadoop and other open-source applications to work seamlessly with AWS. For example, Hadoop clusters running on Amazon EMR use EC2 instances as virtual Linux servers for the master and slave nodes, Amazon S3 for bulk storage of input and output data, and CloudWatch to monitor cluster performance and raise alarms.

You can also move data into and out of DynamoDB using Amazon EMR and Hive. All of this is orchestrated by Amazon EMR control software that launches and manages the Hadoop cluster. This process is called an Amazon EMR cluster.


What does Hadoop do...

Hadoop uses a distributed processing architecture called MapReduce in which a task is mapped to a set of servers for proce…

5 Things About AWS EC2 You Need to Focus!

Amazon Elastic Compute Cloud (Amazon EC2) - is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers.
Amazon EC2’s simple web service interface allows you to obtain and configure capacity with minimal friction.

The basic functions of EC2... 
It provides you with complete control of your computing resources and lets you run on Amazon’s proven computing environment.Amazon EC2 reduces the time required to obtain and boot new server instances to minutes, allowing you to quickly scale capacity, both up and down, as your computing requirements change.Amazon EC2 changes the economics of computing by allowing you to pay only for capacity that you actually use. Amazon EC2 provides developers the tools to build failure resilient applications and isolate themselves from common failure scenarios. 
Key Points for Interviews:
EC2 is the basic fundamental block around which the AWS are structured.EC2 provides remote ope…
