Introducing To Basics Network


Introducing to basics network.

Computer network is a network with wireless media cable made by IT experts to provide "communication" between computers more effectively and efficiently. This computer network is connected starting from 2 or more computers that are interconnected with each other to achieve certain goals. For example sharing resources (printer or file) and surfing the internet. In this case, the methods used for sharing and information keep changing and growing. This is inversely proportional to the "human network" which is limited to face-to-face conversations, media that are successfully captured and captured by communication. The existence of this computer network innovation makes travel data and information more widespread and more variables that can help all sectors of life.

In the practice of applying a computer network, each part of the computer can request or receive a service called (the client) and that provides or sends a service called a server. This pattern is called a client-server system, and is used in almost all the majority of computer network applications.

* (additional information, (data) is a raw fact "raw", which has not been processed and has not been structured and systematic. Whereas (information) is a collection of data that has been processed, so th at it is structured in a systematic and accepted by human mind.)

To support the existence of an adequate computer network in all aspects, we need to pay attention to these 3 important tools that have been discussed in the previous language.
  •  Hardware

Device (hard) on the computer or device that is visible (visible). Like keyboard, mouse, monitor, RAM, motherboard, USB, and others.
  •  Software

The device (software) on the computer (not visible) is on the computer. Like Windows, iOS, Microsoft, and others.
  • Brainware (pemakainya)

The expertise of a computer user determines a process, regardless of the use of the hardware or software that exists. People who are experts in the field of computers are called IT.

Next we need to know what are the network components. Network components consist of:
·         Computer hardware
- (there is a computer that connects to the network. Like the NIC, and modem)
-Printer
-Scaner
·         Network devices
-NIC
-Modem
-Hub
-Switch
-Router
-Firewall
·         Media
-Kabel
-Non kabel (wireless)
·         policy
-Protocol

- All equipment mentioned, must be directly connected (integrated).
- The equipment needed for connection physically (directly) consists of PC, NIC, NETWORK MEDIA, REPEATER/HUB/BRIDGE/SWITCH/ROUTER.

There is a classification of networks that are categorized by distance.
·         Local Area Network (LAN)
-          Oriented in a limited (narrow) area
-          Creating connections between adjacent equipment
-          Providing fulltime connectivity services
-          Network control under local administration

·         Metropolitan Area Network (MAN)
-          Covers a wider area of LAN, such as between regions in one province.
-          Connecting several small networks into a wider area.
-          Example of application: Bank network where several branch offices can be integrated with each other.

·         Wide Area Network (WAN)
-          Has an operating area in a large geographic area
-          Consists of several local network units in areas that are mutually integrated
-          Relationships between LANs use serial technology
-          Network equipment is spread over a large area

Other types of network technology:
·         SAN (Storage Area Network)
-As a storage resource on the network

·         VPN (Virtual Private Netwrok)
-A private network that is built by relying on public network facilities, such as the internet.
-By using VPN allows using a public network for the purposes of local networks, of course, with guaranteed security using a tunnel system.
-There are 3 types of VPN :
Access VPN, providing access to the Small Office Home Office (SOHO)
Intranet VPN, intended for internal pffice connections (used as a remote office)
Extranet VPN, intended for connections between internal networks and business partners

INTERNET
Including a network that is a combination of small networks that exist in the world that joined into a large-scale network in the world. With the same rules it allows several operating systems to communicate with each other.
A network connection is required on:
Phisical connection
-          Pc
-          Network equipment (modem)
     Logical connection
-          Protocol
    Applications to open services on the internet (web browser)

RFM in Business Strategy

RFM Analysis For Successful Customer Segmentation Analysis RFM in Big Data RFM (Recency, Frequency, Monetary) analysis is a proven marketing model for behavior based customer segmentation. It groups customers based on their transaction history – how recently, how often and how much did they buy. RFM helps divide customers into various categories or clusters to identify customers who are more likely to respond to promotions and also for future personalization services. RFM analysis evaluates which customers are of highest and lowest value to an organization based on purchase recency, frequency, and monetary value, in order to reasonably predict which customers are more likely to make purchases again in the future. What are Recency, Frequency and Monetary? ·         Recency      : How much time has elapsed since a customer’s last activity or transaction with the brand. ·     ...

Artifical Neural Network

Artificial Neural Network  is a computational model based on the structure and functions of biological neural networks. Information that flows through the network affects the  a neural network changes or learns, based on that input and output. So the point is  to create a computational system that could solve problems like a human brain. The Neural Networks was founded by  Warren McCulloch and Walter Pitts in 1943. Then it was upgraded with AI (Artificial Intelligence) in 1975 by Kunijiko Fukushima called Artificial Neural Network (ANN) .   Warren McCulloch and Walter Pitts Today  Neural Networks are important in information age, because help society to solve complex problems in real life condition. They can learn from model the relationships between inputs and outputs that are nonlinear and complex; make generalizations and inferences; reveal hidden relationships, patterns and predictions (such as financial time series data) and varianc...

Categories and Types of Artificial Intelligence

AI has 2 categories namely weak or strong. Weak AI also known as narrow AI. Weak AI is an AI system designed and trained for certain tasks. Weak AI can be a virtual personal assistant, like Apple Siri, Amazon’s Alexa, and Google Home. While strong AI, also known as general artificial intelligence, is an AI system with general human cognitive abilities. When a special task is presented, a strong AI system can find its own solution without human intervention. S trong AI acts more like a brain. It does not classify, but uses clustering and association to process data. In short, it means there isn’t a set answer to your keywords.  Beside that, an assistant professor of integrative biology and computer science engineering at Michigan State University, Arend Hintze, categorizes AI into 4 types, ranging from existing AI systems to AI systems that are still in design. The categories are as follows: Reactive machine. An example is Deep Blue, the IBM chess program that defeated Garr...
