Mengapa perlu Router
Sebelum kita pelajari lebih jauh mengenai bagaimana mengkonfigurasi router cisco, kita perlu memahami lebih baik lagi mengenai beberapa aturan dasar routing. Juga tentunya kita harus memahami sistem penomoran IP,subnetting,netmasking dan saudara-saudaranya.
Contoh kasus:
Host X -> 128.1.1.1 (ip Kelas B network id 128.1.x.x)
Host Y -> 128.1.1.7 (IP kelas B network id 128.1.x.x)
Host Z -> 128.2.2.1 (IP kelas B network id 128.2.x.x)
Pada kasus di atas, host X dan host Y dapat berkomunikasi langsung tetapi baik host X maupun Y tidak dapat berkomunikasi dengan host Z, karena mereka memiliki network Id yang berbeda. Bagaimana supaya Z dapat berkomunikasi dengan X dan Y ? gunakan router !
Contoh kasus menggunakan subnetting
Host P -> 128.1.208.1 subnet mask 255.255.240.0
Host Q -> 128.1.208.2 subnet mask 255.255.240.0
Host R -> 128.1.80.3 subnet mask 255.255.240.0

Beberapa Sistem Operasi dalam satu Hardisk/PC
Kadang kita ingin mencoba suatu sistem operasi lain di dalam komputer kita tanpa harus menghapus sistem operasi yang kita gunakan sekarang.
Ada beberapa cara yang bisa kita gunakan. Namun menurut pengalaman penulis (red-entah kalo orang lain), ada satu cara yang paling mudah.
Berikut langkah-langkahnya :
1.Persiapkan sebuah hardisk yang menurut anda cukup untuk sistem operasi yang akan anda install. Disini penulis memakai HD 20GB (hardisk yang cukup murah utk saat ini)
2.Siapkan CD Sistem Operasi yang akan dipasang (Misal: Win98, WinXP, Win2000 & Red Hat 9)
3.Siapkan Software PowerQuest Partition Magic 7 atau 8.

TIPS MENGGUNAKAN DAN MERAWAT FLASH DISK
Baca dengan TENANG dan PERLAHAN...!
Beberapa bulan yang lalu (tahun 2007) aku membeli sebuah FLASH DISK (maaf ya jika salah penulisan) berkapasitas 4 GB. Ini adalah benda kesayangan ku. Kemana pergi, selalu ku bawa. Karena jaman sekarang adalah jamannya digital. Apapun digital, termasuk DATA.
Aku juga seorang yang bisa dikatakan sering keluar masuk WARNET. Aku sering mengumpulkan informasi di sana, tampa harus membeli buku.
Benda ini (FLASH DISK) sangat ku jaga dengan baik (PERAWATAN EKSTRA)
• Tidak ku dekatkan dengan HP, karena bisa menghilangkan DATA.
• Jangan sampai terbanting,
• Jangan sampai bengkok,
• Jangan sampai basah / lembab / panas.
• Tidak terlalu lama berada di dalam port (lubang) USB, karena bisa panas.
• Ku masukkan dalam port USB hanya untuk meng-copy atau menyimpan data, setelah itu langsung cabut.
• Ku simpan di tempat yang baik pula.
Pada tanggal 01 Agustus 2008,
FLASH DISK aku RUSAK TOTAL dan TIDAK DAPAT DIPERBAIKI LAGI. (ada hikmahnya lah)
Masalahnya DI LUAR DUGAAN,
yaitu menyangkut komputer tempat FLASH DISK dimasukkan.
BEGINI CERITANYA ...(hehe9 kaya kismis gitu..)

SUSUNAN KABEL UTP
Unshielded twisted-pair (disingkat UTP) adalah sebuah jenis kabel jaringan yang menggunakan bahan dasar tembaga, yang tidak dilengkapi dengan shield internal. UTP merupakan jenis kabel yang paling umum yang sering digunakan di dalam jaringan lokal (LAN), karena memang harganya yang murah, kinerja yang ditunjukkannya juga relatif bagus. Saya disini akan memberikan solusi bagaimana cara menghapal dengan cepat dua urutan pengabelan yakni Straight dan Cross. Sebelumnya saya akan menjelaskan kegunaan Straight dan Cross. Kabel Straight digunakan untuk menghubungkan NIC dengan Switch atau NIC dengan Hub, sementara kabel Cross digunakan untuk menghubungkan NIC dengan NIC atau Hub dengan Hub.
Berikut ini adalah urutan pengabelan Straight :
Ujung A
1. Putih Orange
2. Orange
3. Putih Hijau
4. Biru
5. Putih Biru
6. Hijau
7. Putih Coklat
8. Coklat
Ujung B
1. Putih Orange
2. Orange
3. Putih Hijau
4. Biru
5. Putih Biru
6. Hijau
7. Putih Coklat
8. Coklat
Berikut ini adalah urutan pengabelan Cross :
Ujung A
1. Putih Orange
2. Orange
3. Putih Hijau
4. Biru
5. Putih Biru
6. Hijau
7. Putih Coklat
8. Coklat
Ujung B
1. Putih Hijau
2. Hijau
3. Putih Orange
4. Biru
5. Putih Biru
6. Orange
7. Putih Coklat
8. Coklat
Cara cepat menghapalnya adalah cukup mengingat OBIC yang artinya Orange, Biru, Ijo, Coklat. Tetapi anda harus menambahkannya dengan warna putih sebelum OBIC di urutkan. Khusus warna biru anda harus merubahnya dengan warna putih hijau bukan putih biru.
Sedangkan untuk kabel Cross anda cukup mengubah urutan 1 pindah ke 3, urutan 2 pindah ke 6 atau dengan kata lain 1-3, 2-6 dari urutan kabel straight. Untuk kabel Cross Ujung A urutannya kabel Straight dan Ujung B dirubah jadi 1-3, 2-6.
Semoga tulisan ini bermanfaat bagi kita semua.. Amin..

7 Tips for Successful Blogging
So, you have a blog! Do you have traffic? Do you know how to build traffic to your weblog? There are seven proven methods for building readership of your blog. They start with defining the purpose, or life, of your blog. Then, after you have a blog worth promoting, driving traffic is crucial to your ongoing success at blogging.
Here are seven tips to help you build and hold an audience for your blog:
Tip #1: Provide quality content.
On the Internet, whether you are talking about websites or blogs, a lot of space is given to content. Everyone directs you to provide quality content. But, what is quality content? The quality of your blog’s content is directly related to how well you have defined your ideal audience.
A successful blog is written with a distinct audience in mind. In this way, you can provide content that is unique to your audience’s issues, needs, or desires. If you create content they like and wish to return to read, you have quality content.
The second issue is to stay true to your audience and tone of your blog. If people are reading your blog, it’s because they like your topic and tone. Try not to stray from your typical topics and style too much. This will give your readers a reason to link back to your blog on an ongoing basis, as will posting on a regular basis.
Tip #2: Blog regularly
If you don't update your blog often enough, blog readers will move on to other blogs. There are too many blogs out there competing for attention. Blog readers will go where they can get enough of what they want.
Successful blogging takes a commitment of your time. When you begin blogging and wish to capture an audience, you should be prepared to blog every day. In this way, you can develop an audience who counts on you to help them begin or end their day.
This means you should also try to post at the same time each day. Your readers will get accustomed to your schedule and check your blog at the appropriate time. The time of day is not as crucial as the consistency in your posting.
Since you now have quality content and a regular posting schedule, it’s time to drive traffic to your blog. Your readers will do a lot to promote your blog just by telling their friends. Don’t count on this alone! You need to do some additional work.
When you post, make sure you set your blog to “ping” blog tracking sites every time you add a new post. Think of this as a means to get their attention. The ping says “Hey, we just added a new post”. An alternative to automatically pinging from your blog is to use pingomatic.com. This is a one-stop place to automatically ping everyone you should notify of your new post and only takes a couple of minutes to accomplish.
Tip #3: Mention your blog wherever you can
Mention your blog’s address in your email signature line, in forums where you post, on your business cards, on address labels and in conversations with anyone you meet. Use a tag line under your blog address to further entice them to visit. Mine reads:
Michele Schermerhorn
http://www.imarketblog.com
A sassy little marketing blog
Beyond just mentioning your blog in writing and conversation, you must actively participate in the blogging community too.
Tip #4: Participate in the blogosphere
Get involved in other people's blogs. Visit blogs that interest you and are in line with the general topic of your blog. Then, leave thoughtful comments. Almost every comment option on someone else’s blog will allow you to post your blog URL and your email address. Help other bloggers out with traffic and they will help you.
If a blogger really likes your site, they will add you to their blogroll. A blogroll is generally found on every blog which understands linking to the rest of the blogosphere helps drive traffic. A blogroll is a listing of other blogs. Think of it as a “recommended reading list”. Don’t be stingy with your blog roll either. Add those blogs that you read and enjoy to your blogroll too.
Tip #5: Think keywords when you post
Think about keywords with your use of titles, links and blog posts. Search engines, like Google and Yahoo, like keywords. The more targeted your keywords, the better the chances of your blog appearing in search results. Search results can drive that extra traffic you want.
To increase the value of the key words in your content, make certain keywords are part of the hot link in your posts. Don’t use “click here” as the hot link. You will be wasting valuable real estate in your post. Instead use the relevant keywords for the hot link, like “a great marketing idea. This gives the keywords added emphasis with the search engines.
One last thought on keywords for driving traffic; if you want a real leg up in the traffic game, in your linking code add rel=”tag”. This helps Technorati, a major blog resource, index your blog for their directory. But don’t stop there! It’s time to submit your blog to blog directories.
Tip #6: Submit your blog to blog directories
In addition to submitting your blog to the major search engines, make certain you submit the blog to exclusively blog directories like blogwise, blogcatalog, or bloghub. Many people find blogs through these online directories.
When you do submit your blog to these directories, remember to add a description that will entice your targeted audience to check your blog out. For instance, when I post my blog in blog directories, under description I put “General musings, rants, advice and strategies from a battle-worn veteran of the Marketing Wars, online and off”. Your description should help the potential reader understand your blogging topic and the flavor of how you write.
In addition to submitting your blog to blog directories, join a few of the free or inexpensive traffic exchange sites like blogexplosion or blogclicker.
Tip #7: Use free and inexpensive blog traffic exchange communities
There are many sites which can be termed “traffic exchange” sites for the blogging community. It won’t cost you anything to sign up. At the very least, join blogexplosion, blogclicker, and blogazoo. Once you sign up, you have two options to help drive traffic to your blog. Use both of them!
The first method is to earn credits (guaranteed visitors to your site) by using the “surf member sites” function. As you surf through those sites, you will be earning credits (visitors to your blog). When you find an interesting post, leave a comment as discussed above. When you find a blogger you like, add them to your blogroll and let them know you did.
The second method to drive traffic is to purchase credits. The cost is very cheap for the traffic you will drive to your blog. The more traffic to your blog, the more customers you’ll have. The more happy customers you have, the more they will tell others. The more they tell others, the more customers you get. Don’t you love this dance!
In summary, blogging may not be for everyone. However, it can be a great method for bringing your unique perspective to the Internet. You will surely find others who think the same way you do. Some bloggers will entertain you, some will inform you, and some will drive you to tear your hair out. Decide what type of blogger you want to be and be the best you can. See you in the blogosphere!
