Menempatkan iklan banner

Menempatkan iklan banner dapat menjadi cara yang sangat efektif untuk pasar bisnis Anda di Internet. Iklan banner dasarnya iklan yang muncul di website, biasanya dalam bentuk kombinasi grafis dan teks, untuk mendorong pengguna internet untuk mengklik iklan tersebut ke website Anda. Bentuk yang paling umum dari iklan banner adalah iklan yang muncul di bagian atas situs web dan bentang lebar halaman web. Iklan ini berasal nama mereka dari kesamaan untuk banner tetapi secara teknis iklan banner dapat datang dalam berbagai bentuk dan ukuran. Artikel ini akan kita lihat efektivitas spanduk serta metode untuk menempatkan iklan banner tersebut.

Iklan banner dapat sangat efektif jika digunakan dengan benar. Namun, menempatkan iklan banner Anda di seluruh Internet dengan sangat sedikit pertimbangan apakah atau tidak lokasi mungkin akan bermanfaat bagi bisnis Anda bukan ide yang baik dan dapat membuang-buang besar uang serta sumber daya lainnya seperti waktu dan usaha. Oleh karena itu pemilik bisnis yang sedang mempertimbangkan menggunakan iklan banner untuk mempromosikan bisnis mereka harus meluangkan waktu untuk belajar bagaimana menggunakan iklan banner secara efektif dan untuk menemukan lokasi yang ideal untuk menempatkan iklan banner mereka.

Lokasi yang paling ideal untuk iklan banner ditampilkan secara jelas di sebuah situs yang menerima banyak lalu lintas situs Web dan juga melengkapi produk dan jasa Anda dengan baik tanpa memberikan persaingan langsung untuk produk atau jasa. Sebagai contoh perhatikan pemilik bisnis yang mengkhususkan diri dalam menjual sepatu atletik khusus untuk pelari. Membeli ruang iklan banner di situs yang menawarkan saran pada pelatihan untuk acara berjalan dan memberikan informasi tentang ras mendatang akan menjadi ide yang sangat baik. Website ini menarik pengunjung yang memiliki minat dalam menjalankan dan cenderung untuk membeli sepatu atletik tapi tidak menjual sepatu lari langsung. Ini berarti website menarik anggota audiens target Anda, tetapi tidak bersaing untuk bisnis Anda.

Selain membeli ruang iklan banner, beberapa pemilik usaha memilih untuk bergabung dengan kelompok pertukaran iklan banner. Ini merupakan alternatif di mana pemilik bisnis tidak membayar iklan banner mereka untuk ditempatkan di situs lain tapi dalam pertukaran mereka setuju untuk memasukkan satu atau lebih iklan di situs mereka sendiri. Ini adalah pilihan yang sangat terjangkau untuk menempatkan iklan banner tetapi tidak selalu strategi terbaik. Hal ini karena pemilik bisnis sering memiliki sedikit masukan ke mana iklan banner mereka muncul dan telah membatasi masukan ke dalam iklan banner yang muncul di website-nya sebagai imbalan. Dalam kebanyakan kasus, pemilik bisnis memiliki kemampuan untuk menolak untuk iklan tuan rumah yang mereka anggap menyinggung tapi tidak dapat secara spesifik memilih iklan banner mereka harus posting.

Akhirnya, ketika posting iklan banner, pemilik bisnis harus menyadari efektivitas iklan mereka tempat. Mereka dapat memilih untuk memasukkan desain yang berbeda untuk iklan banner mereka di website yang berbeda tetapi mereka harus memantau hasil iklan mereka untuk menentukan apakah satu gaya lebih efektif daripada yang lain. Informasi ini dapat menjadi sangat penting. Jika satu gaya adalah menikmati banyak kesuksesan sementara gaya lainnya tidak, pemilik bisnis mungkin ingin menggunakan gaya yang lebih sukses untuk semua iklan banner atau mendesain ulang gaya kurang berhasil untuk membuatnya lebih menarik bagi pengguna internet.

Networking Home Computers

Networking Home Computers
Increasing Productivity With the Whole Family
Have you ever thought about networking your computers at home? If you have a small collection of computers around the house (and a small collection of computer users), you can connect each one of those computers to one another and share data, software, and hardware including a single Internet connection. There are many creative uses for home networking, however it's an ideal situation when upgrading each computer to the same capability is financially out of the question. On a home network, each computer has access to the equipment of the better machine in the group as if that equipment were their own.

Connecting computers with either an Ethernet cable or a Wireless connection can create a home network. The easiest and cheapest method uses an Ethernet connection, which requires a series of network cards, a cable for each computer, and a router. The network card is similar to the old modems we used in the past to connect to the Internet, however in a home network, it's used to communicate with every computer that's connected to it.

You'll want to first, select the computers that will connect to each other and then install the network cards inside each of them. Then you'll connect a cable to each computer that will communicate with the server. These cables won't connect to the server directly. Instead, they'll connect to the router. To enable Internet access for each computer, this router will need to connect with a modem of the host machine.

Once the hardware is set up correctly (you'll need to read the instruction manual of your equipment for details), you can then setup the network from Windows on each machine. Within Windows, you can set up a home network similar to the way that you set up an Internet connection. Only this time, you'll set up a LAN (Local Area Network) connection.

Windows should walk you through setting up a LAN after starting the computer and once complete, you can begin to connect one of your machines to the network. You can do this through Internet Explorer by typing in the address and password required to access the router (the address and password required to access the router will be in the router manual).

Connected to the network, each computer can send files back and forth, open programs on a remote computer, play the sound files and videos located on another computer, and share a single Internet account to browse the web, download files, or chat with someone in an entirely different country.  If a single printer is available on only one computer in the network, every connected PC can send documents to it and print them out. Kids will enjoy the ability to play multi-player games and adults will enjoy the ability to blast a single message to everyone at once or maintain a group schedule.

Since we're describing a home network that will connect to the Internet, you're strongly advised to install a protective firewall program to thwart Internet viruses, worms, or other damaging spyware code. Firewalls prevent - but they don't repair. Only anti-virus and anti-spyware programs can reverse damage. So you should install a firewall on the computer that grants access to the computer, and then install an anti-virus and anti-spyware program on each of the remaining computers in the network.

If you have files that shouldn't be shared (bank statements, credit card information, etc.), you can restrict their access in one of several ways. You can put them in a new folder and then remove the "read" permissions for that folder. Or you can specify who can (and who cannot) access specific files with a password from within Windows Control Panel.

Software Piracy - It's Best To Avoid It At All Costs

Software Piracy
It's Best To Avoid It At All Costs

Like electronic identity theft, computer viruses, and the spread of other computer crimes, software piracy is on the rise. The problem with software piracy is that software costs make this illegal activity appealing to the end user. After all, who is it going to hurt? Rich software companies?? This article investigates software piracy as a whole and the impact that it has on the computer using industry.

The most vulnerable victims of software piracy are software businesses or independent programmers who create and distribute commercial software or shareware. We described shareware in another article, but because both commercial software and shareware require payment, they're the target of pirates who seek to make these kinds of programs free to use.

Depending on their binding legal agreements, licensing typically allows the use of a single program on a single computer. This set up is usually fine for a user who uses software at home on one computer. But in an environment where there are five, ten, twenty or more computers, buying a license for each computer can be down-right costly. So costly that the temptation to pirate a little software here and there can be pretty tempting.

Co-workers are familiar with this temptation and they're often the ones who "share" purchased software among those who need it. However the same temptation also prompts others to knowingly or unknowingly buy bootleg copies of commercial software or registered shareware. 

As tempting as it is, it's still illegal and the punishments/fines for sharing commercial or registered software is too much for one to bear. In recent news, "Yahoo China loses music piracy case (AP via Yahoo! News) A court has ordered Yahoo Inc.'s China subsidiary to pay $27,000 for aiding music piracy, the company and a music industry group said Tuesday."1 Additionally, "EU lawmakers approve prison terms, fines for major commercial piracy (International Herald Tribune) EU lawmakers voted Wednesday for legislation that would set prison sentences and fines for large-scale commercial piracy, but exempt patents and copying carried out for personal use." 2

Fortunately, there are alternatives. Schools can research student versions of commercial software or ask for a school discount. Just because school rates aren't advertised, it doesn't mean that they aren't available.  Freeware or open source software (also described in another one of our articles) is another alternative to pirating commercial-ware, as well as shareware. And using older versions of programs could additionally reduce the costs associated with commercial versions.

Up until recently, public opinion held little faith in freeware or open source software - often regarding it as low-quality knock-off's of better known commercial products. But if you take a good look at what's being offered at no cost, you may be in for a big surprise. The quality of today's freeware and open source software created a strong rift among the commercial community and it's literally driving the competition bananas! So much so, that even some well known software development corporations have joined the cause and built a few freeware open source products of their own!

If you can remember that there are hoards of alternatives to costly commercial software (and you make the effort to get it), you'll discover that you can keep up with the rest of the computer industry at a significantly cheaper cost than if you attempted to pay your way down the software aisle. Software piracy just isn't the answer.

Dust Kills - Cleaning the Unit Fan is Essential Computer Care

Dust Kills
Cleaning the Unit Fan is Essential Computer Care
Between taking care of the household, the kids, the pets, and the district PTA, computer care is probably one of the last things that you think of doing on a regular basis.  Without a regular maintenance schedule however, you could find out (the hard way) that a neglected computer is an energy hog - one that works harder than it needs to and one that could be a financial burden to replace.

Let's talk about maintaining hardware.  So much emphasis is put on maintaining a computer's operating system that we sometimes forget how important it is to maintain a computer's hardware components. Since there can be quite a few components to take care of, let's talk about the most important one.

The most important component of a computer's hardware system is its fan. The fan is located on the computer's CPU unit and when that thing gets clogged with dirt and dust, it can run down a computer faster than you can say, "Something's wrong with my computer and I don't know what it is!" In short, the fan is responsible for keeping a computer's motor cool and this motor is what keeps the computer's hard drive and peripherals functioning the way you need them to, which translates to "fast."

A dirty fan doesn't rotate fast enough to keep that motor cool and a completely clogged fan just stops rotating altogether. This causes the computer's motor to work harder - and a harder working motor can raise the electric bill! Worst case scenario: the motor can overheat and stop working as well. No motor equals no computer.

Keep your computer's fan clean by preventing the fan from getting dirty or dusty in the first place. Use the computer in a dust-free environment and never smoke around it. Nicotine and tar mean certain death when it comes to computer fans, however should you find a need to clean the fan, do so with extreme care.

It's quite easy to cause more damage from cleaning so if you're not comfortable with cleaning your PC yourself, take it to a shop for servicing. Otherwise, you can unplug and disassemble the computer to do it yourself.

You'll need a can of compressed air and an anti-static rag to remove stubborn clumps of dust. Hold the can perfectly vertical and spray the fan being careful not to spray the dust off the fan onto other sensitive parts of the computer like circuit boards or inside the motor casing. Wipe up remaining dust with your anti-static rag and then reassemble the computer.

One thing that you certainly don't want to use to remove computer dust is a vacuum cleaner. Although using a vacuum cleaner seems to make more sense, the strong suction of a vacuum cleaner can actually spark damaging static electricity or dislodge loose cables. You also don't want to use oil-based cleaners. Although Pledge may dust your wooden tables and cabinets to a perfect shine, the oil inside a cleaner like this will erode sensitive computer parts. Stick to a liquid-free dusting method and your dusting routine will be safe enough to repeat as often as you need.

As previously mentioned, preventing dust from entering the computer is extremely important and will reduce the need to open and dust your system in the first place. The severity of outside elements (smoking, humidity, pets, etc.) will ultimately determine how often you'll need to de-dust your machine. But as an average, you shouldn't need to perform this procedure any more than once or twice a year.

The entire exercise should take no more than twenty minutes tops and once complete, you'll immediately see and hear the difference in your machine. The computer's keyboard and mouse will run more smoothly, hardware won't take as long to connect, and the entire machine won't be as loud as one that's corroded with ugly dust bunnies.

What's That File?

What's That File? An Introduction to File Extensions
In an effort to be "user-friendly," Windows (and perhaps some other operating systems) hides the most important part of a file name from new computer users: the extension. Okay - we're assuming that the reasoning behind hiding extensions is a "user-friendly" one because we just can't come up with any other reason for hiding them. No harm could ever come from seeing an extension, but plenty could be learned from it. Fortunately you have this article to guide you through some of the most common extensions that you'll run into.

But pengertian internet dan intranet before you can see file extensions, you need to turn them on. From Windows Explorer, click on the "Tools" menu, and select "File Options." Click the "View" tab and then uncheck the box next to "Hide file extensions for known file types." Click "OK" and you'll notice that the files in Windows Explorer show a dot and group of three letters after their names. That dot and group of three letters is known as an "extension," and the extension explains what kind of file it is.

A file could be a plain text file, an image, a sound, a video, or program. But without seeing the extension, you wouldn't know it unless you double-clicked on it. The following list defines some of the most common extensions that you'll find on your computer.

.au - This extension indicates a sound file. Most sound players will load up and play this kind of file.

.art - This extension indicates an image file that was compressed with AOL (America Online) technology. Both Internet Explorer and the AOL service software can display this kind of file, however if you don't have AOL installed on your system, Internet Explorer will display it.

.avi - This extension indicates a video file playable by most multimedia viewers including Microsoft's Media Player.

.bmp - This extension indicates another image file that might have originated from Windows Paint program.

.dll - This extension indicates a Dynamic Link Library which may contain additional programming code for software. Many different programs often share Dynamic Link Libraries and you'll find a bunch of them in the Windows/System directory (but don't ever delete them)!

.exe - This extension indicates a program or an application like Microsoft Word, Internet Explorer, or Outlook Express. Use extreme caution when downloading .exe files from the Internet since malicious programmers like to hide viruses in these types of files.

.gif - This extension indicates another image file and it stands for "Graphics Interchange Format." .Gif files are often smaller than .bmp files (described earlier) and they're commonly found on Internet web pages.

.jpg - This extension indicates yet another image file and it stands for "Joint Photographers Experts Group." Like the .gif file, it's commonly found on Internet web pages, however it's much smaller than both the .gif image and the .bmp image.

.mid - This extension indicates a sound file created with a Musical Instrument Digital Interface. Windows Media Player will open and run these files, however they don't sound like normal .wav or .mp3 files (described later). .Mid files are designed to product synthetic sounds using a computer's sound card.

.mp3 - This extension indicates a sound file that authentically reproduces voice and/or music. Windows Media Player will open and run this kind of file.

.scr  - This extension indicates a screen saver file.

.sit - This extension indicates a Macintosh archive StuffIt file. They will not open on a Windows system without a special utility.

.ttf  - This extension indicates a font especially designed for use on a Windows system. It stands for "True Type Font."

.txt - This extension indicates a plain text file that can be opened with Notepad.

.wav  - This extension indicates a sound file that like the .mp3 file, can be opened with Windows Media Player or Windows Sound Recorder. .Wav files are much larger than .mp3 files.

.zip - This extension indicates a Windows archive WinZip file. They will not open on a Macintosh system without a special utility.

Viruses

What They Are And One Reason Why People Make Them
Over recent years, computers have become synonymous with viruses and viruses don't show any signs of disappearing any time soon. In recent news, LiveScience.com reported that "Before the month is even done, April has set a record for virus e-mails."1 In the past, we would be comfortable in telling new computer users not to worry about viruses and that catching a computer virus is rare. Today, that would be some of the worst advice we could give anyone. As reported in countless news reports, computer viruses are rampant and they're extremely worrisome. This article will describe what viruses are and then point you in the direction of some rather unique protection and prevention.

In short, a computer virus is a software program designed to destroy or steal data. It attacks computers via distribution - often unknowingly - through email attachments, software downloads, and even some types of advanced web scripting. Viruses that destroy data are known as Trojan horses, viruses that explode their attacks are called bombs, and viruses that duplicate themselves are called worms. Some viruses are a combination of each, however they can be further identified according to where they're located on a computer.

A virus originating from the boot sector of a computer is a boot-sector virus and this nasty devil does its dirty work the moment a computer is turned on. A virus that attaches itself to (infects) other programs is a file virus and activates the moment that an infected program starts. File viruses may also be referred to as parasitic viruses, however should a virus work from both the boot-sector and from an infected program, the virus is then known as a multipartite virus.

Why viruses exist remains a mystery, however we had privy access to the mind behind a virus programmer who explained his motivation behind his destructive inclinations. Apparently, this person had a deep grudge against a popular online service which shall remain unnamed. In this hacker's mind, the online service failed to do a quality job in protecting children from online smut and as retaliation, he created and distributed a virus to as many file libraries of this service as he could. His intentions were to disable the computers of the online service's users so much that they wouldn't be able to connect for days. In his mind, the loss of connection meant loss of revenue for the online service.

Although the malicious code that this person generated may have worked for a small percentage of users, sufficed to say, the online service continued on and still exists today. Despite his motivation or intention, his efforts were null.

We wouldn't be surprised to learn if other motivations behind spreading viruses were similar to this person's, but that doesn't justify the damage that viruses do. Innocent people become pawns for the evil plans of others who've convinced themselves they're doing the "right" thing.

To protect a computer from getting a virus, or clean a virus from a computer system once infected requires the use of an antivirus utility. But may be something else we can do. Perhaps we could make an effort to educate the people who want put viruses into the public about ways to display dissatisfaction with a service or product that don't involve harming innocent parties. In doing so, we just might reduce the number of virus news stories and protect our own investments at the same time. http://news.yahoo.com/s/livescience/20070426/sc_livescience/recordsettingspameffortturnscomputersintozombies

Bluetooth Technical Operations

Bluetooth Technical Operations Bluetooth is a high speed, low powered wireless link technology that's designed to connect phones or other portable equipment together with little to no work required by the user.  Unlike infrared, Bluetooth doesn't require line of site positioning to work.

Current prototype circuits are contained on a board that is 0.9 cm square, with a much smaller circuit board being developed. 

When one Bluetooth device comes in contact with another, they will automatically exchange addresse and details of capability.  Then, they can establish a 1 MB link with security that they will use as required.  The protocols involved with handle both data and voice, with a very flexible topography.

The technology achieves its goal by embedding tiny, non expensive short range tranceivers into the  devices available today.  The radio operates on the 2.45 GHz frequency band, and supports up to 721 KBps, along with three voice channels. 

Each devices offers a unique 48 bit address from
the IEEE 802 standard, with the connections being point to point or multipoint. The max range is 10 meters, although it can be extended to 100 meters by increasing the power.  The devices are also protected from radio interference by changing their frequencies, also known as frequency hopping.

What's important, is the fact that Bluetooth  devices won't drain battery life.  The specification targets power consumption of the device, limiting the drain on the battery.  The radio chip will consume only 0.3mA in stand by mode, which is less than 5% of the power that standard phones use.

Macam macam jaringan komputer Bluetooth will also guarantee security at the bit level.  The authentification is controlled by the user via a 128 bit key.  The radio signals can be coded with anything up to 128 bit.  With the frequency hopping, Bluetooth is already very  hard to listen into.

The baseband protocol is a combination of both circuit and packet switches.  Slots can be reserved for synchronous packets as well.  Each packet  will be transmitted in a different hop frequency. Normally, a packet covers a single slot although it can be extended to cover up to five slots.

Bluetooth can also support data channels of up three simultaneous voice channels. Therefore it's possible to transfer the data while you talk at the same time.  Each individual voice channel will support 64 KB.

From a technical standpoint, Bluetooth is very different indeed.  It's the best wireless method in the world, surpassing even infrared.  For  communication on the go, Bluetooth is indeed very hard to compete with.

Advantages And Disadvantages

Advantages And Disadvantages Bluetooth has a lot to offer with an increasingly difficult market place.  Bluetooth helps to bring with it the promise of freedom from the cables and simplicity in networking that has yet to be matched by LAN (Local Area Network).

In the key marketplace, of wireless and handheld devices, the closest competitor to Bluetooth is infrared.  Infrared holds many key features, although the line of sight it provides doesn't go through walls or through obstacles like that of the Bluetooth technology.

Unlike infrared, Bluetooth isn't a line of sight and it provides ranges of up to 100 meters.  Bluetooth is also low power and low processing with an  overhead protocol.  What this means, is that it's  ideal for integration into small battery powered devices.   To put it short, the applications with Bluetooth are virtually endless. 

Disadvantages Bluetooth has several positive features and one would be extremely hard pressed to find downsides when given the current competition.  The only real downsides are the data rate and security.  Infrared can have data rates of up to 4 MBps, which provides very fast rates for data transfer, while Bluetooth only offers 1 MBps.

macam macam jaringan komputer For this very reason, infrared has yet to be dispensed with completely and is considered by many to be the complimentary technology to that of Bluetooth.  Infrared has inherent security due to its line of sight. 

The greater range and radio frequency (RF) of Bluetooth make it much more open to interception and attack.  For this reason, security is a very key aspect to the Bluetooth specification.

Although there are very few disadvantages, Bluetooth still remains the best for short range wireless technology.  Those who have tried it love it, and
th ey know for a fact that Bluetooth will bearound for years to come.

10 Benefits Of Bluetooth

10 Benefits Of Bluetooth

Below, are 10 benefits and reasons to use Bluetooth
technology.

1.  Wireless
As you probably already know, there are many benefits
and advantages to using wireless devices.  Along with
improving safety as a result of eliminating wires
you don't need, wireless also offers you plenty of
other advantages.  When traveling with your laptop
or other wireless devices, you'll no longer have to
worry about bringing connection cables.

2.  Bluetooth is actually inexpensive
The technology of Bluetooth is cheap for companies
to implement, which results in lower costs for the
company.  These savings are then passed from the
company on to you.

3.  Bluetooth is automatic
Bluetooth doesn't have you set up a connection or
push any buttons.  When two or more devices enter
a range of up to 30 feet of each other, they will
automatically begin to communicate without you
having to do anything. 

4.  Standardized protocol
Bluetooth is standardized wireless, meaning that
a high level of compatibility among devices is
guaranteed.  Bluetooth will connect devices to
each other, even if they aren't the same model.

5.  Low interference
Bluetooth devices almost always avoid interference
from other wireless devices.  Bluetooth uses a
technique known as frequency hopping, and also
low power wireless signals.

6.  Low energy consumption
As a result of Bluetooth using low power signals,
the technology requires very little energy and will
use less battery or electrical power as a result.
This is an excellent benefit for mobile devices,
as Bluetooth won't drain the battery.

7.  Sharing voice and data
The standard for Bluetooth will allow compatible
devices to share data and voice communications.
This is great for mobile phones and headsets, as
Bluetooth simplifies driving and talking on your
cell phone.

8.  Instant PAN (Personal Area Network)
You can connect up to seven Bluetooth devices to
each other within a range of up to 30 feet, forming
a piconet or PAN.  For a single room, you can
also set up multiple piconets.

9.  Upgradeable
Upgradeable is the standard for Bluetooth.  There
are newer versions of Bluetooth in the works,
which offer many new advantages and backward
compatible with older versions.

10.  The technology stays
Bluetooth technology is a world wide, universal
wireless standard.  With it being as popular as
it is, you can count on it being around for years
to come.  As more and more devices start to use
Bluetooth technology, more manufacturers will be
eager to make their products compatible.  A chain
reaction will occur, making Bluetooth the standard
for cutting edge wireless.
