This is a comparison of the C# programming language with the Java programming language. As the two are both garbage-collected runtime-compiled languages with syntax derived from C and C++, there are many similarities between Java and C#. However, there are also many differences, with C# being described as a hybrid of C++ and Java, with additional new features and changes. This page documents the strong general similarities of the languages and then points out those instances where the languages differ. Object handling Both C# and also Java are designed from the ground up as object oriented languages using dynamic dispatch, with a syntax similar to C++. (C++ in turn is derived from C.) Neither language is a superset of C or C++, however. Both use garbage collection as a means of reclaiming memory resources, rather than explicit deallocation of memory. Both include thread synchronization mechanisms as part of their language syntax.  References C# allows restricted use of pointer

Visual Basic (VB), formerly called Visual Basic .NET (VB.NET), is an object-oriented computer language that can be viewed as an evolution of Microsoft's Visual Basic (VB) implemented on the Microsoft .NET framework. Its introduction has been controversial, as significant changes were made that broke backward compatibility with older versions and caused a rift within the developer community. Visual Basic .NET (VB 7) The original Visual Basic .NET was released alongside Visual C# and ASP.NET in 2002. C# — widely touted as Microsoft's answer to Java — received the lion's share of media attention, while VB.NET (sometimes known as VB7) was not as widely covered.[citation needed] [edit] Visual Basic .NET 2003 (VB 7.1) Visual Basic .NET 2003 was released with version 1.1 of the .NET Framework. New features included support for the .NET Compact Framework and a better VB upgrade wizard. Improvements were also made to the performance and reliability of the .NET IDE (particul

A six month project was launched by the 'owners of ITIL', Office of Government Commerce (OGC) based in the UK, on the 8th November 2004, to define the scope of and development plans for a refreshed version of ITIL best practice guidance. The OGC from January through to March 2005 consulted and collected opinions from ITIL users, educationalists and vendors from around the world. Having analysed the feedback the subsequent scope of the ITIL Refresh project was founded based upon areas where high degrees of consensus were found. The development stages started in August 2005 and are planned to be completed in December 2006, with the publication of the 'core' intended for February 2007. The 'core' represents the generic principles of ITIL guidance, but has been expanded to incorporate the life-cycle stages of Service Management. In addition to the 'core' publications will be 'complementary guidance' and 'value added products to assist organi

Brief history of ITIL End of the 1980s Following a series of high profile failed Public Sector IT projects that were reported in the media, resulting in much criticism and debate levied at the government in power, the Central Communications and Telecommunications Agency (CCTA) commissioned and managed the production of the Information Technology Infrastructure Library (ITIL). The production centred on the areas of Service Support and Service Delivery, involving various organizations and experts working in the IT industry sector at the time. 1991 During this period a series of ten books were published covering the areas of ITIL Service Support and ITIL Service Delivery. 1991 The commercial potential of ITIL begins to be realized. A selection of private sector organizations as well as the UK governments Civil Service College are invited to become ITIL training providers. In addition the Information Systems Examination Board (ISEB) part of the British Computer Society (BCS) a

Windows Internet Explorer 8 (abbreviated IE8 ) is a web browser by Microsoft. It is the successor to the 2006 release of Internet Explorer 7, and will be the default browser for the upcoming Windows 7 and Windows Server 2008 R2 operating systems. The browser was released on March 19, 2009 for Windows XP, Windows Server 2003, Windows Vista and Windows Server 2008. According to Microsoft, security, ease of use, and improvements in RSS, Cascading Style Sheets, and Ajax support were its priorities for Internet Explorer 8. uded in MS Office).

Windows 7 (formerly codenamed Blackcomb and Vienna ) will be 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 , netbooks [1] and media center PCs. [2] Microsoft stated in 2007 they were planning Windows 7 development for a three-year time frame starting after the release of its predecessor, Windows Vista . Microsoft has stated that the final release date would be determined by product quality. [3] Unlike its predecessor, Windows 7 is intended to be an incremental upgrade from Vista, with the goal of being fully compatible with device drivers, applications, and hardware with which Windows Vista is already compatible. [4] 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, [5] and performance improvements.

storage area network ( SAN ) is an architecture to attach remote computer storage devices (such as disk arrays , tape libraries , and optical jukeboxes ) to servers in such a way that the devices appear as locally attached to the operating system . Although the cost and complexity of SANs are dropping, they are still uncommon outside larger enterprises . Network attached storage (NAS), in contrast to SAN, uses file-based protocols such as NFS or SMB/CIFS where it is clear that the storage is remote, and computers request a portion of an abstract file rather than a disk block.a Most storage networks use the SCSI protocol for communication between servers and disk drive devices. They do not use SCSI low-level physical interface (e.g. cables), however, as its bus topology is unsuitable for networking. A mapping layer to other low-level protocols is used to form a network: ATA over Ethernet (AoE), mapping of ATA over Ethernet , Fibre Channel Protocol (FCP), the most prominen

What are IP Phones? IP phones, also called VoIP phones, SIP phones, Internet phones or broadband phones , are designed to connect directly to the Internet through a local broadband or WIFI connection. Internet phones (IP) can be wired and wireless (Wi-Fi) IP enabled . The big three manufactures of VoIP phones today are Cisco, Snom and Polycom . Some Cisco IP phones also offer video, however both parties need to have a video IP phone to make a video call. VoIP phone functionality can also be implemented with a PC or laptop if you have the Softphone software and a headset or microphone and speakers. Hot deals on wifi+phone and sip+phone

What hardware do you need for VoIP? Basically three things are required: High speed broadband internet connection Standard home phone (almost anyone will do) VoIP adapter of VoIP software There are a number of various devices out on the market right now to help with the use of VoIP: ATA Adapter IP-PBX Systems SIP & VoIP Gateways VoIP Switches VoIP Routers Broadband Internet A high speed internet connection, otherwise known as a broadband internet connection , is one where you are able to send and receive information on the Internet at a high speed rate. Hence the name, 'high speed internet'. Your local cable or phone company may already be providing high speed service such as 'cable Internet' or 'DSL' service. Hot deals on voip+router and vonage

Consumer market Example of VoIP adapter setup in residential network A major development starting in 2004 has been the introduction of mass-market VoIP services over broadband Internet access services, in which subscribers make and receive calls as they would over the PSTN. Full phone service VoIP phone companies provide inbound and outbound calling with Direct Inbound Dialing. Many offer unlimited calling to the U.S., and some to Canada or selected countries in Europe or Asia as well, for a flat monthly fee as well as free calling between subscribers using the same provider. These services have a wide variety of features which can be more or less similar to traditional POTS. There are three common methods of connecting to VoIP service providers: A typical analog telephone adapter (ATA) for connecting an analog phone to a VoIP provider An Analog Telephone Adapter (ATA) may be connected between an IP network (such as a broadband connection) and an existing telephon

Voice over Internet Protocol (VoIP) is a general term for a family of transmission technologies for delivery of voice communications over IP networks such as the Internet or other packet-switched networks. Other terms frequently encountered and synonymous with VoIP are IP telephony, Internet telephony, voice over broadband (VoBB), broadband telephony, and broadband phone. VoIP systems usually interface with the traditional public switched telephone network (PSTN) to allow for transparent phone communications worldwide. VoIP systems employ session control protocols to control the set-up and tear-down of calls as well as audio codecs which encode speech allowing transmission over an IP network as digital audio via an audio stream. Codec use is varied between different implementations of VoIP (and often a range of codecs are used); some implementations rely on narrowband and compressed speech, while others support high fidelity stereo codecs.

Channel types A channel is a communication link used by distributed queue managers. There are two categories of channel in MQ: Message channels, which are unidirectional, and transfer messages from one queue manager to another. MQI channels, which are bidirectional , and transfer MQI calls from a MQ client to a queue manager, and responses from a queue manager to a MQ client. There are two types of MQI channel : server-connection and client-connection. The definition of each end of a message channel can be one of the following types: Sender Receiver Server Requester Cluster sender Cluster receiver Do not confuse message channels with MQI channels. There are two types of MQI channel : server-connection and client-connection. A message channel is defined using one of these types defined at one end, and a compatible type at the other end. Possible combinations are: Sender - Receiver Requester - Server Requester -

DLQ If a message arrives at a queue manager but there is no queue there to receive it, the message is put on the dead-letter queue as usual. If there is no dead-letter queue, the channel fails and retries , as described in the MQ Intercommunication book. Again : For example, if an application tries to put a message on a queue on another queue manager, but gives the wrong queue name, the channel is stopped and the message remains on the transmission queue. Other applications cannot then use this channel for their messages. Again : If you do not, and the MCA is unable to put a message, it is left on the transmission queue and the channel is stopped. Again : If all the retries are unsuccessful, the message is written to the dead-letter queue. If there is no dead-letter queue available, the channel stops. You can create it by using the DEADQ attribute on the ALTER QMGR command to specify one later. DLQ monitor : MS71 ! How

IBM WebSphere MQ is a family of network communication software products launched by IBM in March 1992. It was previously known as MQSeries, a trademark that IBM rebranded in 2002 to join the suite of WebSphere products. WebSphere MQ is IBM's Message Oriented Middleware offering. It allows independent and potentially non-concurrent applications on a distributed system to communicate with each other. MQ is available on a large number of platforms (both IBM and non-IBM), including z/OS (mainframe), OS/400 (IBM System i or AS/400), Transaction Processing Facility, UNIX (AIX, HP-UX, Solaris), HP NonStop, OpenVMS, Linux, and Microsoft Windows. Message-oriented middleware Main article: Message-oriented middleware A member of the WebSphere family from IBM, WebSphere MQ (formerly MQSeries) is the most popular system for messaging across multiple platforms, including Windows, Linux, IBM mainframe and midrange, and Unix. WebSphere MQ is often referred to as "MQ" or "MQSer

Clustering Main purpose : workload balancing. Distributed queing is when you group queue managers in a cluster : the queue managers can make the queues that they host available to every other queue manager in the cluster. Any queue manager can send a message to any other queue manager in the same cluster without explicit channel definitions, remote-queue definitions, or transmission queues for each destination. Every queue manager in a cluster has a single transmission queue from which it can transmit messages to any other queue manager in the cluster. Each queue manager in a cluster needs to define only: one cluster-receiver channel on which to receive messages one cluster-sender channel with which it introduces itself and learns about the cluster which own queues it wants to make available to the cluster As with distributed queuing, an application uses the MQPUT() call to put a message on a cluster queue at any queue manager.
