USB sekarang sudah versi 3.0 Sekilas jika kita perhatikan hampir tidak ada perbedaan antara USB 2.0 dan USB 3.0. Secara fisik ukuran mereka sama. Sekilas yang membedakan satu USB 2.0 dan USB 3.0 adalah USB 2.0 memiliki bantalan berwarna putih sedangkan USB 3.0 memiliki bantalan berwarna biru. Apakah ini hanya akal-akalan tengkulak produsen USB agar pasar mereka meningkat dari orang-orang yang ingin meng-upgrade piranti keras? Apakah USB 2.0 bisa disambungkan ke USB 3.0 atau sebaliknya? atau mungkin timbul pertanyaan apa sih bedanya USB 1.0, USB 2.0 dan USB 3.0?

Sebenarnya USB 1.0 mulai dikenal sejak awal tahun 1996, namun teknologi ini mulai populer pada saat munculnya Teknologi USB 2.0 di pertengahan tahun 2000 (dengan kecepatan sampai 40x USB 1.0 yaitu 480 MBits/s dan tolerasi pensinyalan data pada ± 500ppm). Kemudian berlanjut pada tahun 2008 USB 3.0 mulai dikenalkan.

Mudah kok, cara merawat sound system.
Merawat Sound System

Merawat
3 unit besar or 3 bagian besar dari sound system itu sendiri, yaitu :
1.
Signal dan Power amplifier unit
Untuk unit signal dan power amplifier yang perlu dilakukan
adalah menjaga agar kondisi ruang penyimpanan perlengkapan tersebut berada pada
kondisi kering dan tidak berdebu. Usahakan untuk menjaga bagian dalam enclosure
power amplifier dan signal unit tetap kering. bisa dengan cara meletakkan
kantung Silica Gel/desiccant untuk menyerap uap air agar tetap kering. Uap air
akan menyebabkan korosi/karatan di bagian kaki2 komponen, bagian dalam kabel
rangkaian dan trafo, dan korosi pada junction dan hubungan kabel dapat
menyebabkan meningkatnya nilai tahanan/resistansi yang berpengaruh pada
kualitas suara peralatan PA (Public Address) yang kurang prima.

PORT - PORT TCP & UDP YANG PALING SERING DIGUNAKAN
Dalam protokol jaringan TCP/IP,
sebuah port adalah
mekanisme yang mengizinkan sebuah komputer untuk mendukung beberapa sesi
koneksi dengan komputer lainnya dan program di dalam jaringan. Port dapat
mengidentifikasikan aplikasi dan layanan yang menggunakan koneksi di dalam
jaringan TCP/IP. Sehingga, port juga mengidentifikasikan sebuah proses tertentu
di mana sebuah server dapat memberikan sebuah layanan kepada klien atau
bagaimana sebuah klien dapat mengakses sebuah layanan yang ada dalam server.
Port dapat dikenali dengan angka 16-bit (dua byte) yang
disebut dengan Port Number dan diklasifikasikan dengan jenis protokol
transport apa yang digunakan, ke dalam Port TCP dan Port UDP.
Karena memiliki angka 16-bit, maka total maksimum jumlah port untuk setiap
protokol transport yang digunakan adalah 65536 buah.
Dilihat dari penomorannya, port UDP dan TCP dibagi menjadi tiga jenis, yakni sebagai berikut:
Dilihat dari penomorannya, port UDP dan TCP dibagi menjadi tiga jenis, yakni sebagai berikut:
Jenis – Jenis Port Jaringan dan Fungsinya
Apabila kita mendengar nama Port, maka yang langsung
terlintas di pikiran kita pastinya merupakan sebuah socket khusus yang
ditempatkan pada sebuah komputer yang berguna untuk menghubungkan kabel
dan perangkat tertentu. Hal ini mungkin ada benarnya.
Port fisik adalah port yang kita ketahui secara luas. Port fisik dapat dilihat dan kita rasakan secara fisik. Fungsi utama dari port fisik ini pun untuk melakukan penghubungan dua atau lebih komponen yang nyata secara fisik, misalnya menghubungkan antara komputer dengan server dengan kabel, ataupun perangkat lainnya.
Port logic. berbeda dengan port fisik, port logic merupakan jenis port yang tidak dapat terlihat secara fisik, dan tidak dapat kita pegang atau raba. Tetapi port logic ini juga memiliki fungsi yang sama untuk saling menghubungkan antar perangkat melalui protocol ataupun melalui media lainnya.

Tips To Avoid Computer Viruses
Computer and laptop viruses, seem to be proliferating faster than the
diseases they were named after and like the organic varieties the
instigators and malicious coders who design these programs are making
them harder to detect and they are also coming up with new delivery
methods.
These malicious programs, which probably started life as playful
code, have evolved into rather potent tools capable of making even the
most advanced IT infrastructure hidden behind hardware firewalls grind
to a halt.
This is the main reason why you should always keep your antivirus
software up to date. Last month’s or even last week’s virus definition
data base will not be enough to protect you from the latest incarnation
of even an older virus
The Computer Virus
A computer virus, a devastating type of software, designed to target
your computer and cause absolute chaos. This virus has the potential to
cause major problems and in some cases, damaging your computer hardware
and possible data loss. Much like an organic virus that infects living
things, a computer virus can also make your computer very sick.
A virus can attach itself to any application in your program directory, such as a word processing application. Each time the application runs, so does the virus. During this process, it is the perfect time for the virus to replicate, infecting more unsuspecting applications. This may cause serious damage to your operating system. If you suspect your PC becomes infected with a computer virus, it will need to be taken to an accredited computer service center.

5 Ways to Watch TV and Movies on Your iPad
The iPad can perform many wonderful feats. One of our favorites — its ability to stream television shows, movies and even some live broadcasting on a high-res screen. And we don't even have to tote around a heavy laptop.
ABC was the first major network to allow iPad users to stream full episodes. Ever since, many other networks have jumped on the mobile bandwagon. For the most part, these apps are free of charge. Most importantly, they're filled with full episodes of the shows you missed or want to watch again.

Movies and TV
You’ve probably already heard about Netflix and Hulu, both of which have compatible iPad apps. These popular options are only accessible though paid subscriptions, which cost $7.99 per month.
If you don't want to shell out the cash, you can access other platforms to stream movies. Crackle, for instance, may be more limited in terms of available content, but it is free to download and easy to navigate. The service offers movies and TV shows, as well as originally produced programming, such as The Unknown, a horror series starring Dominic Monaghan, of Lost and Lord of the Rings fame.
For another free option, try TV.com. The app includes shows from CBS, The CW and Showtime, searchable by channel, title or popularity.
If you're looking for timeless entertainment, try Tap TV, a platform full of hundreds of old cartoons, the best YouTube videos, silent classics and documentaries. Curators hand-select felicitous content to populate this app.
Browsing
Sleek and simple in design, NextGuide is a personalized program guide that aggregates information across multiple video apps and keeps you informed about when and where your shows are playing. You can customize notifications for certain actors or even your favorite sports team.
Similarly, use BuddyTV to select your favorite shows and personalize your viewer preferences. Soon enough, the service gives you suggestions based on what you chose. An in-app TV guide allows you to select your favorite channels and see what is airing at that very moment. Additionally, you can view previews, recaps and opt for reminders when your favorite shows are about to air.

You'll also find that a lot of cable TV providers offer livestreams within their own apps. See: Cox TV Connect, DirectTV, Time Warner, Cablevision and DISH Network. Most also allow you to set your DVR and turn your iPad into a remote control.
Interactive

Facebook stock jumps 12.6 percent as share lockup expires
Shares of Facebook Inc jumped nearly 13 percent on Wednesday, as investors breathed a sigh of relief that expiring trading restrictions on a huge block of shares failed to trigger an immediate wave of insider selling.
"While the lockup is expiring, there is nothing requiring anybody to sell," said Tim Ghriskey, chief investment officer at Solaris Group in Bedford Hills, New York. "Given the low price, these long-term holders are deciding to hold the stock, and that is lifting it here as the fear of the expiration subsides."
Roughly 800 million Facebook shares were eligible for sale on Wednesday after restrictions on insider selling were lifted on the biggest block since Facebook's May initial public offering.
The lockup expiration greatly expands the 921-million-share "float" available for trading on the market until now.
"We've seen this before with other lockups. People sell them leading up to the lockup period expiring, and then they have a bit of a relief rally," said Ryan Jacob, chief executive of the Jacob Funds, which does not own Facebook shares.
In August, shares of the online reviews website Yelp Inc surged by more than 20 percent on the day that insider trading restrictions expired. That stock's rally was boosted as short-sellers scrambled to cover their positions when the expected flood of selling failed to materialize, say analysts.
Facebook shares finished Wednesday's regular trading session up 12.6 percent at $22.36 on the Nasdaq, with trading volume for the stock more than four times the average during the past 50 days.
The world's No. 1 online social network became the only U.S. company to debut with a market value of more than $100 billion. But its value has dropped nearly 50 percent since the IPO on concerns about money-making prospects over the long term.
Insider trading lockup provisions started to expire in August, and the rolling expirations have added to the pressure on the stock.
Restrictions on insider selling have expired in waves. A limitation on more than 200 million shares expired on October 29.
COST OF SHORTING
Pivotal Research Group analyst Brian Wieser said he did not expect Facebook insiders to sell all of their shares as the lockups expired.
"I would expect heavy volumes over the next few weeks, but not undigestible volumes," said Wieser. By his estimate, roughly 486 million of the nearly 800 million newly freed Facebook shares will be sold.
There is some evidence the heavy interest in "shorting" the stock was dissipating, given the poor performance since it first sold shares in May. Investors who believe a stock will fall can bet against it by shorting the stock - that is, borrowing it and selling it in the hopes it will decline.
According to Markit, a financial information services company, about 28 percent of the shares available for short-selling were being borrowed for that purpose, down from a high of more than 80 percent in early August.
Similarly, SunGard's Astec Analytics, which also tracks interest in shorting, noted that the cost of borrowing Facebook shares is down more than 50 percent since the beginning of the month.
"Everything would seem to indicate the market is losing its appetite to short Facebook," wrote Karl Loomes, market analyst at Astec.
The cost of shorting Facebook has declined to 0.18 percent on an annualized basis, Astec said on Wednesday. By contrast, shortly after the IPO, the cost to short the stock ranged from 40 percent to 50 percent annually.
"It's become somewhat of a controversial stock. It always adds fuel to the fire if you have a sizable short position," said Stephen Massocca, managing director at Wedbush Morgan in San Francisco.
"But the unlock is not new news. It doesn't mean everyone is going to sell, and it doesn't mean every order is going to come in today."
Facebook, with roughly 1 billion users, has faced a tough reception on Wall Street amid concerns about its slowing revenue growth and nascent advertising efforts on mobile devices.
But the company delivered better-than-expected third-quarter results on October 23 and revealed that 14 percent of its advertising revenue is now from mobile ads, reassuring some investors it was beginning to figure out how to earn money from smartphone and tablet users.
"They had a pretty good quarter. I think a lot of investors, though, are waiting to see some consistency in the results," said Jacob.
Several members of Facebook's senior management have sold millions of dollars' worth of shares in recent weeks through pre-arranged stock trading plans as lockup restrictions expired.
Chief Operating Officer Sheryl Sandberg has sold roughly 530,000 shares this month, netting just over $11 million, though she still owns roughly 20 million vested shares in Facebook.
In August, Facebook board member Peter Thiel sold roughly $400 million worth of Facebook stock, the majority of his stake, when an earlier phase of lockup restrictions expired.
Facebook's 28-year-old chief executive, Mark Zuckerberg, has pledged not to sell any shares before September 2013.
"I'm sure we're seeing some selling from guys whose shares are unlocking, but the supply is not nearly as much as everybody expected," said Arvind Bhatia, an analyst with Sterne, Agee & Leach.
