The Network Is The Computer

When I started my research Web 2.0 technologies as part of the process of teaching and learning, I am reminded of an incredible foresight, John Gage, one of the founders of Sun Microsystems. In 1984, he uttered a phrase that has become the mantra of the Sun. "The network is the computer" Put that date in perspective, 1984 was the year of the first user interface of the mass market of computer graphics (Macintosh) is published. It would be more than ten years before the graphical browser (Mosaic) would make his first appearance. The networks were the province of universities and defense. What was your thinking about Gage?

Now with the advent of Web 2.0 technology and ubiquitous WiFi access, it is very clear what it meant to Gage. For activities which most of us do most of the time, the network we have access to far more important that the entity through which access is achieved. Online, we can write (and shop and work together) documents, build spreadsheets, save and share photos, maintain collections of bookmarks, develop and deliver presentations, to publish his own work, read the news and correspond with others with almost any device that can access a wireless network. For this work, it does not matter if you use Mac, Windows or a version of Linux you just need a Web browser. Rising, he did not even need a computer in connotative meaning Phones, Pocket PCs and game machines, even can perform most of these functions.

Web 2.0 has created a major change in my thinking on the web. In the "old days" I saw the Internet as a book with a very good index. It was exciting to be able to quickly find updated information, but like all books, the information was static and one-sided. I was an observer and did not participate.

Now I see the web as a laptop, a place not only find information but also for storage. action, and even participate in its creation and dissemination. Tools like Google Notebook JetEye and allows me to keep (and share) the notes I am researching online. I can add my knowledge or comments about wikis, blog comments, access pictures of my former students, attend meetings, and subscribe to a variety of interesting information via RSS. My access device could be my laptop, but also could be my PDA or cell phone. As these devices increasingly converging in terms of functionality, it is hard to imagine a single device, without much in the form of local storage or operating system that will do everything possible. Then, the network will actually be the computer.

As educators, we must consider how to take the functionality of the web tool for students. E 'common practice in K-12 education to make "web search", in essence, a guided tour through some of the pre-selected web pages designed to answer some of the issues identified. It has 21 century equivalent to "read the chapter and answer the questions," we all suffered at school. Many teachers think that because students are encouraged to use the safety guide to find the answers, but they are "to integrate technology in classrooms." This is a "book" on the network, of which above. The problem is that most students, this approach is so twentieth century. I went beyond its own use of the Web (think Facebook, MySpace, Flickr, etc.) and expectations about how the web should work for them. For them, the network is an interactive medium, and have become accustomed to the participants.

The Network Is The Computer

London is now the town of Cisco in San Jose, California is owned by the city's Convention Centre Excel.

On the evening of Monday, the company has recently appointed Director of Technology and Cloud Computing, Valley veteran Lew Tucker hosted a dinner attended by President and CEO John Chamber of Commerce Keynote Presentation on Tuesday.

Mr. Tucker was wise to take on Cisco, which is one of the companies, which show that the old adage that when the gold rush, sell shovels. Cisco makes the routers, probably one of the less glamorous aspects of the Internet, you can imagine. Not that they are the mind and the market value of about 117 billion dollars.

Mr. Tucker, a former director of cloud computing, Sun Microsystems, until he purchased the Oracle, and has a long career in time for Salesforce and Thinking Machines, he predicted a world of clouds, which companies use special offer vertical expertise or responsibility and control, medical services and banking, for example. Or maybe the clouds geographical constructed in accordance with local regulations (such as information requirements in the EU, for example).

next wave of computing has three key aspects. It is characterized by ubiquitous mobile devices such as smartphones and tablets. They speak with cloud data and applications running on powerful servers. But linking the two, and the glue that holds them together, "said Tucker, is the network itself.

He predicted a more rational way of various network protocols and access to a set of APIs (Application Program Interface), you are essentially turning online forum, and not just a tool that allows applications and data transfer.

Perhaps, finally, a somewhat enigmatic slogan allegedly coined by his former colleague, vice president of Sun Microsystems John Gage again in late 1990, "The Network Is The Computer" can actually be observed. Not that anyone really understood what it meant at that time.

More Application Servers: BEA WebLogic Server 7

BEA WebLogic Server 7.0 Release Candidate

WebLogic Server initial costs of implementation and training, and emphasis on developing high-end EJBs, making it a major infrastructure commitment. Them at the forefront of Java technology value of its standards of market leader, and its clustering and high availability.

Cost Analysis

WebLogic Server is a big ticket purchase, and costs can easily migrate hundreds of thousands of dollars on a cluster of application servers. Other alternatives can do much that WebLogic is not much less, but the level of support and industry-standard Java are incomparable.

+ New tools for developing J2EE application development easier, security system that offers greater scalability and manageability, while the cost of transition to the new security API, built on the LDAP server and UDDI.

- Companies are expensive to buy, build and maintain a WebLogic Application Manager tool has little ability to constantly monitor server activity.

Mature App Server: ColdFusion MX Server Beta

ColdFusion MX Server beta

ColdFusion MX combines ease of use and rapid development, Cold Fusion Markup Language and support industry and the maturity of Java application server. Organizations that want to quickly introduce script-based Web applications should consider this alternative access. However, it is advisable to proceed slowly until a new engine in this publication has been on the market for some time to track down bugs.

Cost Analysis

They cost less than $ 1000, ColdFusion fits the budget of all departments. actual cost of the compromise between the developer of cost (low, especially compared to Java) and the transition costs required to move the code of low-level programming language, when the site grows.

+ Can function as a component in a Java application server, allowing the same server for ColdFusion and JSP applications, components provide a new encapsulation own logic and language can be published as Web services, XML native type, the XPath query and XSLT support.

- Some older programs must change to run.

ColdFusion Reborn

ColdFusion is doomed to ship next month. Professional Edition (the version we tested) would cost $ 799 per server and upgrades, $ 549 per server.

This is a hot product for hot prices especially considering the search engines included in the text and graphics generation.

ColdFusions reasonable prices also gives developers more freedom to prototype applications without fear of deadlock: the ColdFusion code can be run within a Java application server to provide a safe way to growth and "small" applications, which become strategic tools of society.

ColdFusion Server Enterprise Edition (which supports server clustering) costs U.S. $ 4,999 per server, ColdFusion MX for J2EE, the version that runs inside the servers of third-party application, is priced at $ 3,999 per processor. Macromedia JRun (which is integrated in the low-end versions of ColdFusion MX), IBM WebSphere and iPlanet s Sun Microsystems Inc. will initially be supported by ColdFusion MX for J2EE with BEA WebLogic Server certification comes later this year.

ColdFusion MX Server, which runs on Windows, Linux, Solaris or HP-UX, is a bottom-up and re-write the biggest change since ColdFusion was first released. With this release, ColdFusion web pages are not interpreted by a database engine for C-runtime, but now they are compiled into Java bytecode and runs in a Java application server.

Unfortunately, the JSP (JavaServer Pages) or Java is not inserted directly into the ColdFusion pages, although the Cold Fusion can use the JSP custom tag libraries via a special interface and call any JavaBean or a method defined by a file Java class. ColdFusion or JSP pages and servlets can also share the application, session and application variable information.

But the real value of ColdFusion has always been the language, not the server. EWeek Labs believes ColdFusion CFML (ColdFusion Markup Language), the easiest scripting language to learn, and it does not sacrifice power for simplicity (though it is more detailed than Microsoft Corp. Active Server Pages or PHP PHP groups). This update combined with CFML maturity and a superb cross-vendor support of J2EE world.

This change is very strategic for enterprise customers who previously had to balance the rapid development of ColdFusion and the developer base, with its status as a supplier and the additional cost of maintaining and even an application server (especially the one without the support of the industry at large).

During the experiments, we found ColdFusion MX is fully compatible with most ColdFusion applications. Our bookstore Nile reasonably complex reference, written for ColdFusion Server 5.0, running on the first try, when we tested with ColdFusion MX.

There are a number of compatibility of reservations with less common ColdFusion tags, but Macromedia has a tool for analyzing source code that identifies the areas where you can upgrade problems can occur.

ColdFusion MX installer did an excellent job porting options for existing ColdFusion the new model. We were asked to manually edit our Oracle and DB2 data connections for obtaining and running, but this amounted to only a few minutes of work. ColdFusion includes Java Database Connectivity drivers for all major databases.

The portion of C for a Java engine can result in a decrease in performance, but Macromedia has compensated for this by build ColdFusion pages, instead of interpreting them. Macromedia staff said its tests showed similar performance between ColdFusion and ColdFusion MX 5.0, with some functions a little faster and a little slower some MX.

We did their tests, comparing the two using the Nile Bookstore and stated that the ColdFusion MX was actually a bit 'faster for most users to download. We conducted the tests, Quest Software Benchmark Factory Inc.s load testing tool (, and tested one of 100 concurrent users who do not have time to think.
The change of platform is the largest circulation in the long term for ColdFusion MX, but native XML and Web services support, and enhancements CFML are also strong attractions. ColdFusion can still access the Microsoft Component Object Model objects as before in a Java-COM bridge supplied with the product.

XML data objects can be handled as native data types in ColdFusion (like a table) and the server now includes XPath query and XSLT (Extensible Style Language Transformation) properties.

A new component object responds to a weakness of many years in CFML: their inability to encapsulate the code effectively. Components allow inheritance, and function of the components can be converted to SOAP (Simple Object Access Protocol) Web based simply adding a "remote" attribute to the function.

ColdFusion MX users to find a stable partner for the development of future instruments Macromedias Dreamweaver MX. Dreamweaver MX combines two lines of business development tool, Dreamweaver and HomeSite, a single well-integrated web development tool.

Dreamweaver MX, which runs on Windows and Mac OS offers a Web site and page editing functions in CFML pages, as well as many other types of pages: simple HTML, JSP, ASP, ASP. Net (C # and Visual Basic. NET) and PHP. The package is scheduled to ship later this month to $ 399 per song.

We were regular users of JRun Studio (the home version of the site) has a number of years, and Dreamweaver will be taken on the characteristics of packet editing, automatic tag completion, the database files, navigation and use.

Its interface is a marvel of depth, but at the expense of some clutter folding windows platforms, which have labels, menus that have remained open to see, like a Mandelbrot fractal.

Beta 3 of the Code, that the test was also significantly unstable, crashing several times a day. With a file, the cut consistent text when published. He expressed the hope that these issues will be removed from the final version.

Beas New Direction

The tools are a key component of BEA this year. Although WebLogic Server includes several new tools itself, BEA WebLogic Workshop, sold separately, which really impressed us to the test. WebLogic Workshop and the inventiveness of the graphical style was a surprise, because a development tool that producers lame server applications have a history of producing.

WebLogic Server 7.0 became available April 30 when we finished testing the release candidate, and costs $ 10,000 per CPU. It runs on Windows, most Unix operating systems, OS/400 and OS/390. WebLogic Workshop is scheduled for next month. (BEA has not announced pricing yet.)

In version 7.0 of WebLogic server itself, a new WebLogic Builder tool provides a separate program for deployment descriptors and WebLogic Edition EJBGen a new tool that automatically creates the descriptors of the home interfaces and remote control and the implementation based on JavaDoc comments in the cloud.

Security has been completely revised in WebLogic 7.0, which includes an integrated LDAP user management, a model much better approach than simple text file that has been the default in WebLogic 6.1. Security is now based on the standard Java security (SSPI Security Service Provider Interface), and editor of the policy, it is easier to change the security settings via centralized policy management in one interface.

UDDI (Universal Description, Discovery and Integration) 2.0 server is also the use of internal Web services.

WebLogic Administration Console is largely unchanged from version 6.1 and follow the performance statistics to the lack of object level, for example, the figures indicating the EJB (Enterprise JavaBeans) had a longer treatment.

The main purpose of WebLogic Workshop (and something pleasantly) is wrapping EJB interfaces for networking, database content, Java Message Service queues or other network services. Support for J2EE (Java 2 Enterprise Edition) connectors are designed for shipping a release, but was not present in the beta version we used.

In eWeek Labs' tests, created Web services and connect them to the back-end content very easy to use intuitive interface packages. Graphical tools and source code editor is automatic each other to date, and editor noted for syntax errors in real time.

WebLogic Workshop Web service is a little close attention, leaving general Java and web development space of the tool. Also, as mentioned above, WebLogic Server 7.0 requires to run the applications it generates.

However, WebLogic Workshop run Excel advanced features of J2EE, in particular, message queuing, a surprisingly simple. Tests have shown the influence of space management, automatic data integrity and the generation of EJB, so it's much easier to build complex applications.

In addition, Message service listeners turning Java web service-based cows were as simple as turning a cache option. When we split a synchronous Web service in a two-speed asynchronous service by adding a callback request, all variables within our web application was automatically matched with the message ID Web service and stored or loaded from bean entity created automatically if necessary. Session Manager is completely transparent to our application.

WebLogic Workshop using simple source language metadata tags have popularized the concept. NET, and Bea was smart enough to borrow the concept. This may become more common in the Java world, where the draft of Java Specification Requests 175 and 181 are the Java standard. Currently, WebLogic Workshop Web service labeling system (based on comments javadoc) is not supported by anyone else at risk at an early stage.

WebLogic Workshop uses a loosely coupled Web services interfaces and Java classes. We could for example change the name of Java class names of parameters independently of XML elements or XML structures and use mapping software data clearing system.

This mapping system worked using text placeholders for variable names map Java for XML documents as input or output.

When we have Java, WebLogic Workshop automatically creates the corresponding XML document with placeholders for each parameter of the method. We could then modify the XML code freely, provided that all the placeholders remained.

App Servers Mature

Web application servers have reached an important level of maturity: The market is evolving at a slower pace, and theres a lot more attention to maintaining the servers in production environments and compression, plus the value of existing investments. In addition, application server vendors are increasingly specialized development tools for your access server technology more complex.

This is good news for enterprise IT managers, and clearly show two major releases Application Server: BEA Systems WebLogic Server 7.0 Macromedia ColdFusion MX server Inc.s.

The first adds performance and reliability features that provide a stronger basis for WebLogic stores, is a completely new server, which aligns with the space of Macromedia's Java application server.

Because the application server-based scripting language, ColdFusion MX to a much wider and less technical than the market of WebLogic Server. (ColdFusion MX is able to operate within WebLogic by the end of the year). WebLogic is an infrastructure at the application server and requires a lot of rarefied skill set, although the BEA tool for developing a new strategy, the goal is to change just that.

EWeek Labs tested the two application servers as a release candidate, with beta versions of the associated development tools from BEA, and Macromedia, which will help reduce costs and accelerate the development and integration efforts.

Beas latest development kit is an impressive WebLogic Workshop. Macromedia, in turn, release a solid update to the popular forums Dreamweaver, Dreamweaver MX. WebLogic Workshop applications are running WebLogic Server 7.0, so these two elements are much more closely than they are, ColdFusion MX and Dreamweaver MX. Even if ColdFusion users tend to find a better instrument for development there, Dreamweaver MXS strong support for all major web scripting languages ​​means that will appeal to a wide range of web developers.


A mouse is a small device used to identify and select items on the computer screen. Although mice in many ways, the conventional mouse is a bit like a real mouse. It's small, rectangular, and is connected to the CPU by a long wire that resembles a tail. Some mice are the latest wireless.The mouse is usually two buttons: the left mouse button (usually the left button) and a secondary button. Many of the mice in a wheel between the buttons, you can navigate without problems of screens of information.
When you move your mouse hand, the pointer on the screen moves in the same direction. (Appearance of points can change depending on where it was placed on display.) When you select an item, select an item and then select '(short press) the primary key. Pointing and clicking with the mouse is the primary way to interact with the computer.

Floppy Drive

Floppy disk drives store data on floppy disks or diskettes also called. Compared to CD and DVD discs can contain only a small amount of data. They also recover more slowly and are more susceptible to damage. For these reasons, floppy disk drives are less popular than they used to be, although some of the computers that contain them.Why disks "floppy"? Although the outside is hard plastic, it's just the sleeve. The disc is made within a thin, flexible vinyl.


CD and DVD drives

Almost all computers today come with CD-ROM or DVD drive, usually located on the front of the unit. CD drives use lasers to read (retrieve) data from the CD, and many CD drives can also write (record) data directly from the CD. If you have a disc burner, you can store copies of files on a blank CD. You can also use the CD player of a music CD in your computer.
DVD players can do what the CD, plus DVD playback. If you have a DVD player, you can watch movies on your computer. Many DVD drives can write data to blank DVD discs.


If you have a CD or DVD drive, periodically back up (copy) important files to CD or DVD. In this way, if your hard drive fails, never lose data.


The team has one or more disk drives that store information devices in a metal or hard plastic. The album retains information even when the computer is off.

Hard Disk
the computer's hard drive stores information on a hard disk, a rigid tray or a stack of discs with a magnetic surface. Because hard disk
s can contain large amounts of information, usually serve as the primary means of storage of equipment, keeping almost all of your programs and files. The hard disk is usually located inside the unit.

PC Parts

Parts of a computer
If you use a desktop computer, you may already know that there is no single piece, called "computer". The computer system is really a lot together. The physical components, which you can see and touch, are collectively called hardware. (Software, on the other hand refers to the instructions, or programs that tell the hardware what to do.)

The illustration below shows the most common material in a desktop computer system. Your system may seem a little different, but it most su
rely these parts. A laptop computer has similar parts but combines them into one package size laptop.

Let's take a look at each of these parts.
