Cloud Computing is More About Business Than Technology

Cloud Computing is More About Business Than Technology. The adoption of Cloud Computing Services and the related technologies is often mistakenly considered to be a purely tactical choice, when in fact linked to the long-term strategic choice. Cloud Computing is not like some more powerful engine that can be automatically started in place of the previous technologies but it should be accompanied by a new planning by an organization or individual for the adoption of cloud services.

In Cloud Computing Platform, Not Using the Features Means Wastage

In Cloud Computing Platform, Not Using the Features Means Wastage of Money.It is estimated that over 40% users of cloud wastes money by not using all features. When you need to work in Cloud Computing Platform like from Rackspace, Amazon Web Services, HP Cloud ; it can happen that the IT administrators of your company often buy more than they really need or under use less expensive add ons. This phenomenon exclusively happens in Cloud Computing Platform as most thinks that Cloud Computing is like some more powerful engine that can be automatically started in place of the previous technologies.

Permalinks and WordPress : a basic primer

Arrived in 1999 in the world of blog, the permalinks are permanent URLs that are used to refer a blog (among other reasons). The term permalink is derived from the words “permanent” and “link”.

For a blog that can be cited continually in forums, emails, diggs, social networks, or be part of the bookmarks of users, it is advisable to ensure the permanence of these URLs (long term factor) .

Permalinks are frequently used by news sites and mainly by content management software (CMS): WordPress, DotClear, Blogger, Movable Type. Some of them use URL rewriting, and more specifically the Apache module mod_rewrite to implement the rewrite system (we will go in detail later).

According to the possibilities they offer, permalinks can present several types of URL structure explicit. They generally consist of a domain name, category, date (day / month / year), and the title of the blog. The order of the elements that make up the structure of the URL may vary.

How does a modem work?

There are main two types of modems

The modem is a device used to connect the Internet using a telephone or dedicated line. There are two types of modems, one that is most widespread is the internal modem. It is located inside the casing and is located on a PCI slot.

The second is the external modem that is located outside the computer. It is connected to the PC via a cable. The advantage is that it is portable, it can be moved.

Functions of a modem

The modem is used to translate information, it can modulate and demodulate (hence its name).

Modulation is to convert data sent and received by a computer on the telephone line (which are not directly understandable) into information that is compatible with the computer.

Demodulation is the reverse, it converts the data coming from the telephone line and received by the computer into information understandable by the latter.

Modulator: Computer -> Modem -> Phone Line

Demodulator: Phone line -> Modem -> Computer

Speed of a Modem

We obtain the speed modems by calculating the amount of information it can send and receive on the telephone line in a second. It is expressed in bits per second (bps). Very fast speed is expressed in kilobits per second (Kbps). So: 56000 bps = 56 Kbps.  Voiceband modems generally remained at 300 and 1,200 bit/s (V.21 and V.22) into the mid 1980s. A V.22bis 2,400-bit/s system similar in concept to the 1,200-bit/s Bell 212 signalling was introduced in the U.S., and a slightly different one in Europe. By the late 1980s, most modems could support all of these standards and 2,400-bit/s operation was becoming common.

The speed is usually expressed in Kbps or Mbps. There are standards designed for modems manufactured by different companies can communicate with each other without any problem.

There are high-end modems with extra features (voicemail, fax etc. …) but the price is high.

Radio modems

Direct broadcast satellite, WiFi, and mobile phones all use modems to communicate, as do most other wireless services today. Modern telecommunications and data networks also make extensive use of radio modems where long distance data links are required. Such systems are an important part of the PSTN, and are also in common use for high-speed computer network links to outlying areas where fibre is not economical.

Mobile modems and routers

Modems which use a mobile telephone system (GPRS, UMTS, HSPA, EVDO, WiMax, etc.), are known as wireless modems (sometimes also called cellular modems). Wireless modems can be embedded inside a laptop or appliance or external to it. External wireless modems are connect cards, usb modems for mobile broadband and cellular routers. A connect card is a PC card or ExpressCard which slides into a PCMCIA/PC card/ExpressCard slot on a computer. USB wireless modems use a USB port on the laptop instead of a PC card or ExpressCard slot. A cellular router may have an external datacard (AirCard) that slides into it. Most cellular routers do allow such datacards or USB modems. Cellular Routers may not be modems per se, but they contain modems or allow modems to be slid into them. The difference between a cellular router and a wireless modem is that a cellular router normally allows multiple people to connect to it (since it can route, or support multipoint to multipoint connections), while the modem is made for one connection.

Broadband

ADSL modems, a more recent development, are not limited to the telephone’s voiceband audio frequencies. Some ADSL modems use coded orthogonal frequency division modulation (DMT, for Discrete MultiTone; also called COFDM, for digital TV in much of the world).

Cable modems use a range of frequencies originally intended to carry RF television channels. Multiple cable modems attached to a single cable can use the same frequency band, using a low-level media access protocol to allow them to work together within the same channel. Typically, ‘up’ and ‘down’ signals are kept separate using frequency division multiple access.

New types of broadband modems are beginning to appear, such as doubleway satellite and power line modems.

SIM Card or Subscriber Identity Module

SIM card is a smart card in a mobile phone which plugged in and used to identify the user within the network. This makes phone connections and data connections. SIM card has a small processor with memory. Previously we wrote about USB Modem, like Mobile phones, these also uses a SIM card. SIM stands for Subscriber Identity Module.

Technology behind SIM Card or Subscriber Identity Module

By using a variable PIN, SIM card can protect against unauthorized use. Using the SIM card the Mobile Equipment (ie usually the mobile phone) is assigned to a network and is authenticated. For these purposes are on the SIM card there are secret numbers and algorithms which are stored on ROM. These are also used to encrypt voice and signaling data. The SIM card is also used to store temporary, network-related data as well as preferred and blocked networks. In addition, telephone and short message service messages (SMS) and the memory of the last called telephone numbers can be stored on SIM card.

Picture : A SIM card seen with contrast X-Ray.

SIM card is often used in large ID-1 format (85.6 mm × 54 mm). The smaller ID-000 -part (25 mm × 15 mm) can be broken out from it. Due to the even smaller mobile devices the small ID-000 format is used. Meanwhile, there are also devices that uses even smaller micro-SIM.

A SIM card contains eight contact surfaces. They are named as C1 to C8. There are SIM cards with an operating voltage of 1.8 volts, 3 volts and 5 volts.

More on SIM Card

SIMware is the software running on a SIM card. SIM cards can not last forever. With every write to the card (eg for a authentication in the network), the process “ages” the card. Most manufacturers specify a life of 100,000 authentication. Older cards are sometimes not recognized in modern mobile phones. Current UMTS devices definitely need a map of the latest generation of its storage service features. Some SIM cards have a lifetime internal counter. The micro-SIM (3FF) Third Form Factor card is a smaller version of the SIM card. When the technical specifications of the chips are concerned, there are no significant differences with a normal SIM Card.
