1. Networking Terminology
When designing a network bandwidth usage is very important and determines the data transfer. Layer model is used to describe the functions in the network such as the Open Systems Interconnection (OSI) and the Transfer Control Protocol / Internet Protocol (TCP / IP) either in a LAN, MAN, WAN, SAN and VPN.
This section will discuss data networks, network devices, topology and bandwidth usage, identification bps, kbps, Mbps, the bandwidth throughput, data transfer calculations, the approach to the OSI model and TCP / IP model, identification of network devices that are used.
1. Data NetworkData networks that exist today are part of the process and the work of a business application that was written by a personal computer, when the personal computer is not connected into a network then there is the inefficient use of working time even with the calculation of a cost effective business . Imagine if someone working at a large company and will do the copying files or copying files then it will do is walk into a place where the source data is stored, it will be very tiring and time consuming. How does communication work in order to be effective? So what solutions do to address these conditions?,
things to do is to build a network of computers working environment. By building a standard local area network (LAN) then the exchange of data or information between the personal and the inside of an enterprise can be resolved quickly and accurately.
The distance data transfers in a network will affect network devices, cabling, topology and type of network usedComputer network based on area or wide area
Based on the area or an area, a computer network can be divided into three, namely:
# - LAN (Local Area Network)
# - MAN (Metropolitan Area Network)
# - WAN (Wide Area Network)
LAN or Local Area Network is;
Figure 2:36 Local Area Network
computer network to areas that are not so widespread.
Limits the size of a LAN is a single building.
Example of a LAN is a network located in schools that connect computers belonging to students, the teacher's computer and the computer's administrative section. In LAN we can workgroup or a collection of multiple computers or users that make sharing resources or sharing resources.
For example, a workgroup comprised of user guru1 teacher, guru2, guru3 and so on,
while the student workgroup comprised of user siswa1, siswa2 and so on.
Use of this workgroup will facilitate the handling or management network.
Benefits of using LAN are:
# - Each user can exchange files (file sharing) is easy
# - Each user can share the printer (printer sharing)
# - Each user can store the data centrally (file server)
# - Each user can communicate with each other using a computer.
MAN or Metropolitan Area Network is; Figure 2:37 Schematic Metropolitan Area Network
computer network that connects computers within a city.
Examples of this network is a network between several schools in one city.
MAN same concept as the LAN, which make sharing resources or sharing
resources, it's just a broader scope.



WAN or Wide Area Network is; Figure 2:38 Schematic Wide Area Network
computer network with the widest geographic coverage to reach
Another island, another country, another continent, and even outer space.
WAN is usually a collection of a number of LAN and MAN.
Examples of application of the WAN is a network-owned banks nationwide
For example: Bank "A" which is headquartered in Jakarta has a branch office in Surabaya, Makassar and Denpasar. Bank "A" also opened overseas branches in the
in Singapore, Malaysia, and Philippines.
In each branch, the bank has its own office with a number of staff and full facilities including ATMs (Automatic Teller Machine).
To obtain accurate information from all branches of financial transactions,
Bank "A" create a network of computers belonging to the category of WAN.
The advantage of using a WAN are:
a. computer servers to data centers can be centralized in one location
b. inter-branch communication can be done using e-mail or chat is cheaper than telephone communications
c. documents can be sent in the form of electronic mail, thereby reducing the cost and hassle of shipping documents through the post office.

Ethernet data cable

Color Code
Ethernet data cable consists of four pairs of wire. Each has a specific color (solid) with her partner berwarnah white stripes specific color (solid), twisted into one. For Ethernet performance is good, do not open too long wrench (about ¼ inch).


Color code on the cable pair
Pair 1: putih-biru/biru (white-blue/blue)Pair 2: putih-orange/orange (white-orange/orange)Pair 3: putih-hijau/hijau (white-green/green)Pair 4: putih-coklat/coklat (white-brown/brown)
Design for 10BaseT Ethernet are orange and green. Two other pairs, brown and blue, is not used. The following configuration uses an RJ-45 cable
There are two standard ethernet cables for this, namely T-568A and T-568B. The picture above shows both standards are. Standard T-568B, orange and green pairs are placed on pins 1, 2 and 3, 6. Standard T-568A turned orange and green connections, so the pair of blue and orange into 4 pin in the middle, which mebuat such connections is more suited for telco voice connections.
T-568A has been used as a standard installation, while T-568B only as an alternative course.
Cross-over Cable (Cross Cable) EthernetCable Ethernet / LAN has 8 wires (4 pair). For the needs of Trust connections that use cable, Ethernet requires 2 pairs of wire, one pair serves as the "transmit" and one pair of longer serve as a "receive".
Pin Configuration:
Pin 1 - Pin 3Pin 2 - Pin 6
Connections like this are used to connect:
1. Hub to Hub.2. Switch to switch3. Computer to computer4. Router Ethernet port to port Router Ethernte5. Computer to Router6.Komputer to IP Modem (modem output in the form of an Ethernet card)
Cable "Straight-Through"Configuration cable "straight-through" for Ethernet is, pin 1 on the connector is connected to pin 1 on the opposite end of the connector, so it goes to pin 2 to 8.
Cable Connection "Straight-through" is used to connect:1. Between Computer to Hub2. Between the Computer to the Switch

Know Your Business on the Internet

by Putu Meiyanto 
internetbusiness.gifMas Putu, I'm really so confused by the wealth of information about business opportunities on the Internet, there is a shape MLM, online social gathering, the publisher advertising, brokerage sales of goods, etc.. Where the hell can that be trusted? (Faith, Jakarta) 
Business on the Internet where the heck is aliases do not cheat? This is the core question of Faith and also mas may question all of us. What is certain online MLM and pyramid-shaped social gathering money can not be trusted. Even if we get the profit from that process, there are dozens, hundreds or even thousands of people under the root of our detriment. What about other Internet business? Let's discuss. 
We can conclude that the business on the Internet is actually composed of two types, namely the business of selling products on the Internet and advertising business by becoming a publisher on the Internet. Both are complete I peeled off in the following explanation. 
1. BUSINESS SELLING PRODUCTS ON THE INTERNET 
Businesses selling products as usual, just use the Internet to display products, arrange booking and payment system online. Usually referred to as e-commerce. For example, Amazon.Com which sells books, CDs, software and other products on the Internet. Example in Indonesia is Bhinneka.Com, which provides computers and peripheral products that allow transactions over the Internet. Businesses can also be done by individuals, for example, a programmer who sell their own applications, templates, themes, modules, and plugins that he developed, through his personal website. Usually the seller using e-commerce systems like zencart and oscommerce which in addition features a product catalog, also allows online payment with payment gateways like paypal, 2checkout.com, etc.. Once again that the products sold could be, books, magazines, ebook, software, documents, furniture, electronics, computers, cellphones, etc.. 
2. BUSINESS PUBLISHER BE ADVERTISING IN THE INTERNET 
This is the kind of business on the Internet that are loved by many people, and in it I might as well;). Capital is relatively small, because we only need to charge for the domain, hosting and web site. In fact we can use a free blog or a web service used to start our business from small. The most important thing in this business is IDE in building a website or blog and its contents. Web sites or blogs that we build must be unique, anti-crowd (not many other people did), and should be able to attract Internet users to visit it. In other words, we should be able to choose a high traffic site, because this is where the power of the Internet business of this type. The higher traffic to our site, the higher the income we receive as more and more advertisers who want to advertise on our site. 
In America, there is Joel Comm, author of the book Adsense Secrets that could result in an average 500 USD per day or Ken Calhoun could get $ 300,000 per year with DayTradingUniversity.Com site. Let us remember that such major sites as well Friendster.Com life of the business became publisher of this ad. What about Indonesia? There are big names such as Cosa Aranda who was said to have earned more than 5000 USD per month from the publisher ad business on the Internet. 
Ok what kind of business ads on the Internet this publisher? 
A. AFFILIATE PROGRAM 
Program where website owners or blog will get a commission (or gift) in case of transactions between the company owner of the program to buyers of products advertised by the site owner or blog. Amazon.Com has an affiliate program (affiliate programs) is quite famous. We live register and advertise products on the Amazon.Com web site or blog. We'll get a commission (percentage of commission depending on the product) if there are people buying products Amazon.Com through our site. Several other companies that provide affiliate programs are: 

    linkshare.com 

    clickbank.com 

    cj.com 

    sitesell.com 

    clicksor.com 
B. ADVERTISING PROGRAM 
Program where website owners or blog to earn money by advertising from the program owner. Large sum of money received depends on the regulations made by the owner of the program. This type of advertising program could cost per 1000 impressions (CPM) or Pay Per Click (PPC). So different from the affiliate program, the advertising program is the money received is not based on transactions that have been done, but based on the number of ads aired aka impression (CPM) or the number of clicks on the ads (PPC) done by visitors to our site. 
Examples of companies that have a CPM program is fastclick.com and valueclickmedia.com. While based PPC is Google Adsense, which is currently a favorite advertising program for Internet businesses in the world. Other companies that have service advertising programs include the following: 

    adbrite.com 

    text-links-ads.com 

    vibrantmedia.com 

    yesadertising.com 

    searchfeed.com 

    crispads.com 

    onemonkey.com 

    industrybrains.com 

    doubleclick.com 

    kanoodle.com 
Direct Advertising is also developing systems where we are the owner of the website or blog does not use the services of advertising companies, but we own a direct hunting and manage ads. Detik.com, kompas.com and banner advertising services systems in other news portal is one example of Direct Advertising. Direct Advertising is also starting to bloom conducted individually by the bloggers who have a high bertraffic blog site. I had tried to Direct Advertising for my personal blog site, although I eventually loose again because I think it really is not very "elegant" advertisements on a personal blog site. Not elegant I mean here is, less clean design and I am disturbed by fear of independence blog advertising products related to opinions that I wrote. With the development time, hopefully someday I can live with that: D But I still apply the Direct Advertising at another site that I built. 
It should be noted that each company has its own rules and mechanisms for the advertiser and publisher ad. We must examine the various rules that they pour in the form of Term of Service (ToS) before we follow the program of a company. 
Interested to follow play in this Internet business? I will discuss in detail the various Internet business that I have introduced over the next article. At least I started the business programs on the internet that I have lived and managed to get income.Follow along this series of articles.
