IP Address

For those of you who study Internet and Computer Communications and Networks, must be familiar with the name IP Address. IP Address is a numbering on a computer as an identity. If simplified, are like a house address name. Thus each computer has a numerical address of each - each. One to another will not be the same or unique.

IP Address that is often used is to use the base TCP / IP because it is simpler and easier to understand. While at OSI Layer itself has its own IP Address, which is of course different from the TCP / IP. But in this world that is more commonly known and used IP Address TCP / IP (Read: The History and Development of the Internet).

IP Address itself is divided into two, namely IP Address Private and Public IP Address. Private IP Address normally be obtained by the home user or small scale. The Private IP Address obtained after subnetting. Public IP Address is usually held on a large scale, such as Hosting, ISPs, data centers, and enterprise Web.

Install Connector Cable Network

To install an RJ-45 connector on the cable UTP There are two types of installation:

Type straight and Type cross

1. Type straight

is used to connect a computer to the hub / switch hub

The order of installation:

Standard A:

A tip of the tip B

1. Green White

2. Green

3. Orange White

4. Blue

5. Blue White

6. Orange

7. Brown White

8. Brown

6. Green

7. Brown White

8. Brown

2. The type of cross / cross

specifically to connect two computers directly without using a hub / switch hub. For now cross type can be used to connect a computer to the hub. The latest Hub own auto sense so that it can detect the type of cable attached.

Types, Networking

TYPES OF NETWORKING

Generally, a computer network can be classified into five categories, based on geographical reach, distribution of sources of information / data, data transmission media, the role and relationship of each computer in processing the data, and based on the type of topology is used. Here's the full translation:

Cyber Ethics

CYBER ETHIC'S THEORY

Cyber ​​ethics is an unwritten rule known in the IT world. A values ​​are agreed to be followed in which user interaction technology, particularly information technology. The absence of clear limits physically as well as the extent of the use of IT in various fields make everyone who uses information technology would be expected to comply with the existing cyber ethics.

Cyber ​​ethics bring new opportunities in education, business, government services with their internet presence. Thus developed the netiquette / nettiquette is one of the ethical references in communicating using the Internet, guided by the IETF (the Internet engineering task force), which sets RFC (netiquette guidelies in a request for comments)

Computer Network

The word "computer network" may already be familiar to our ears, considering almost every day we involve the computer network in our work.

The computer network is a system that consists of two or more computers connected to each other through a transmission medium or communication medium that can share data, applications and the sharing of computer hardware.

The term computer network itself can also be interpreted as a collection of a number of communication terminal consisting of two or more computers connected to each other.

Purpose of the Network is to make the information / data that brought the sender (transmitter) can be up to the recipient (receiver) with precise and accurate.

Computer networks allow users to communicate with each other easily.

In addition, the role of computer networks is needed to integrate data between client computers so diperolehlah a relevant data.

CyberSpace

cyberspace

Cyberspace (English: cyberspace) is the electronic media in a computer network that is widely used for communication purposes one way or reciprocal online (connected directly). The virtual world is an integration of various communications technology equipment and computer networks (sensor, transducer, connections, transmissions, processors, signal, controller) that can connect communications equipment (computers, mobile phones, electronic instrumentation, etc.) scattered all over the world interactively.

About Cyber

Cybercrimes is a term that refers to criminal activity with a computer or computer network into a tool, target or scene of the crime. Included into cybercrimes include online auction fraud, check forgery, credit card fraud / carding, confidence fraud, identity fraud, child pornography, etc..

CYBER LAW
Cyber ​​Law is a legal term that is related to the use of information technology. Another term used is the law of Information Technology (Law of Information Techonology) Cyber ​​Law (Virtual World Law) and Law mayantara. The terms of birth because Internet activity and usage of information technology-based virtual. Cyber ​​law terms used in this paper is based on the premise that if the cyber synonymous with "virtual world" will be enough to face problems when associated with the verification and enforcement. Given the law enforcement agencies will face difficulties if it should prove an issue that is assumed to be "virtual", something that is not visible and apparent. On the internet it is cyber law law, the law specifically applies in the cyber world. Broadly cyber law not only covers crimes on the internet, but also the rules that protect the perpetrators of e-commerce, e-learning; holders of copyrights, trade secrets, patents, e-signature; and many more.
