Windows 7

Windows 7 (formerly codenamed Blackcomb and Vienna) is the next release of Microsoft Windows, an operating system produced by Microsoft for use on personal computers, including home and business desktops, laptops, Tablet PCs, and media center.
Microsoft stated in 2007 that it is planning Windows 7 development for a three-year time frame starting after the release of its predecessor, Windows Vista, but that the final release date will be determined by product quality. Unlike its predecessor, Windows 7 is intended to be an incremental upgrade with the goal of being fully compatible with existing device drivers, applications, and hardware. Presentations given by the company in 2008 have focused on multi-touch support, a redesigned Windows Shell with a new taskbar, a home networking system called HomeGroup, and performance improvements. Some applications that have been included with prior releases of Microsoft Windows, most notably Windows Mail, Windows Calendar,^{[citation needed]} Windows Movie Maker, and Windows Photo Gallery, are no longer included with the operating system; they are instead offered separately (free of charge) as part of the Windows Live Essentials suite.

Web Hosting

A web hosting service is a type of Internet hosting service that allows individuals and organizations to provide their own website accessible via the World Wide Web. Web hosts are companies that provide space on a server they own for use by their clients as well as providing Internet connectivity, typically in a data center. Web hosts can also provide data center space and connectivity to the Internet for servers they do not own to be located in their data center, called colocation.


Types of Hosting:

• Free web hosting service: is free, (sometimes) advertisement-supported web hosting, and is often limited when compared to paid hosting.
• Shared web hosting service: one's Web site is placed on the same server as many other sites, ranging from a few to hundreds or thousands. Typically, all domains may share a common pool of server resources, such as RAM and the CPU. A shared website may be hosted with a reseller.
• Reseller web hosting: allows clients to become web hosts themselves. Resellers could function, for individual domains, under any combination of these listed types of hosting, depending on who they are affiliated with as a provider. Resellers' accounts may vary tremendously in size: they may have their own virtual dedicated server to a colocated server.
• Virtual Dedicated Server: dividing a server into virtual servers, where each user feels like they're on their own dedicated server, but they're actually sharing a server with many other users. The users may have root access to their own virtual space. This is also known as a virtual private server or VPS.
• Dedicated hosting service: the user gets his or her own Web server and gains full control over it (root access for Linux/administrator access for Windows); however, the user typically does not own the server. Another type of Dedicated hosting is Self-Managed or Unmanaged. This is usually the least expensive for Dedicated plans. The user has full administrative access to the box, which means the client is responsible for the security and maintenance of his own dedicated box.
• Managed hosting service: the user gets his or her own Web server but is not allowed full control over it (root access for Linux/administrator access for Windows); however, they are allowed to manage their data via FTP or other remote management tools. The user is disallowed full control so that the provider can guarantee quality of service by not allowing the user to modify the server or potentially create configuration problems. The user typically does not own the server. The server is leased to the client.
• Colocation web hosting service: similar to the dedicated web hosting service, but the user owns the colo server; the hosting company provides physical space that the server takes up and takes care of the server. This is the most powerful and expensive type of the web hosting service. In most cases, the colocation provider may provide little to no support directly for their client's machine, providing only the electrical, Internet access, and storage facilities for the server. In most cases for colo, the client would have his own administrator visit the data center on site to do any hardware upgrades or changes.
• Clustered hosting: having multiple servers hosting the same content for better resource utilization. Clustered Servers are a perfect solution for high-availability dedicated hosting, or creating a scalable web hosting solution.
• Grid hosting : this form of distributed hosting is when a server cluster acts like a grid and is composed of multiple nodes.
• Home server: usually a single machine placed in a private residence can be used to host one or more web sites from a usually consumer-grade broadband connection. These can be purpose-built machines or more commonly old PCs.

VoIP

VoIP User is a community driven and financed SIP based VoIP network. The projects aim is to introduce people to the concept of VoIP by allowing members to experiment with SIP and IAX2 devices.

The VoIP User network was designed to operate within a community environment and therefore differs substantially from most other VoIP networks. The main highlighted difference being that users can call PSTN phone numbers through VoIP User's PSTN gateway without incurring any call charges.

There is a cap on call routes (which may vary) meaning the VoIP User PSTN gateway will only route calls to any country which can be achieved for 2.5p/min (pence a minute) or less. This is mostly landlines, but does include some mobile phones. A full country list is available, as is a fair use policy.

The maximum allowed call time per call is currently 10 minutes.

Data on calls routed between the PSTN and the internet by the VoIP User network can be seen on their analytics page.

Members can obtain a UK non-geographic inbound phone number at no cost which can be routed to any landline throughout the world, or any SIP or IAX2 based VoIP device.

Netbook

A netbook is a light-weight, low-cost, energy-efficient, highly portable laptop that achieves these parameters by offering fewer features, less processing power and reduced ability to run resource-intensive operating systems (e.g., Windows Vista).

Suitable for web browsing, email, and general purpose applications, netbooks are targeted increasingly at users accessing web-based applications, also known as Cloud computing, that do not require intensive resources available on the client computer.

History

Led by the popularization of small-form-factor laptops by Asus and then others, the term 'netbook' became a widely used and genericized industry classification rather than a reference to a particular product. By April 2008, Intel had begun officially using the term netbook to recognize a specific sub-category of laptops.

The term had existed previously – although related to specific products rather than a category of laptops:

• Psion in 1999 had used the product name 'netbook', and in 2008 claimed trademark rights to the term where used in a product name.
• MSI had registered the product name Wind Netbook.
• Coby Electronics had registered the product name Coby Netbook.

The influx of small form factor laptops categorized as netbooks began in 2007, when Asus unveiled the Intel Celeron-based ASUS Eee PC running a customised version of Linux with a 7-inch (18 cm) color screen.^[6] These netbooks measured 8.9 × 6.5 in (23 x 17 cm), featured less-than-full-sized keyboards, and could be customized by users to run alternate operating systems.

In mid February 2008, Everex launched its VIA chipset based CloudBook, running gOS. The CloudBook is based on the VIA nanobook reference design. In contrast to its closest competitor, the Eee PC, the CloudBook has a hard disk drive.

In June 2008, MSI launched the MSI Wind including Bluetooth, a 10" (25 cm) LED, backlit, 1024x600 screen, and an Intel Atom processor — the first netbook to offer the processor.

A number of other netbooks followed, and by late 2008, Netbooks had begun to take market share away from laptops and sales are projected to increase up to 50 million by the year 2012. In Q3 2008, netbook sales overtook iPhone sales by 900,000 units.

It is estimated that 11.4 million netbooks were sold in 2008, up from 400,000 in 2007. For 2009, sales are expected to grow 189% to 21.5 million. Early January 2009, two companies introduced ARM architecture based models.

Laptop Computer

A laptop computer, also known as a notebook computer, is a small personal computer designed for mobile use. A laptop integrates all of the typical components of a desktop computer, including a display, a keyboard, a pointing device (a touchpad, also known as a trackpad, or a pointing stick) and a battery into a single portable unit. The rechargeable battery is charged from an AC/DC adapter and has enough capacity to power the laptop for several hours.

A laptop is usually shaped like a large notebook with thickness of 0.7–1.5 inches (18–38 mm) and dimensions ranging from 10x8 inches (27x22cm, 13" display) to 15x11 inches (39x28cm, 17" display) and up. Modern laptops weigh 3 to 12 pounds (1.4 to 5.4 kg), and some older laptops were even heavier. Most laptops are designed in the flip form factor to protect the screen and the keyboard when closed.

Originally considered "a small niche market"and perceived as suitable for "specialized field applications" such as "the military, the Internal Revenue Service, accountants and sales representatives", battery-powered portables had just 2% worldwide market share in 1986. But today, there are already more laptops than desktops in the enterprise and, according to a forecast by Intel, more laptops than desktops will be sold in the general PC market as soon as 2009.
