Over the last thirty plus years, in which computer software applications have been vital to business operations, the concept of client/server applications has evolved. In the early 1980’s the term, Client/Server, primarily referenced capabilities of new powerful centralized hardware. The computer world is different today and the concept is better defined as a system where the different logical components are separated from each other. The first of the three basic logical components is the Presentation
Comparison Summary DBMS Server Comparison Supplement An Analysis Of The Strengths And Weaknesses Of The Big Six Database Servers. In 1991 I performed a thorough evaluation and comparison of the four major DBMSs at the time: Informix, Ingres, Oracle, and Sybase. This comparison was done for a client building a huge distributed database application, currently in its second phase of d evelopment, with the first phase running successfully country-wide. At that stage, the distinguishing criteria
Introduction This paper will compare and contrast five different database management systems on six criteria. The database management systems (DBMS) that will be discussed are SQL Server 2000, Access, MySQL, DB2, and Oracle. The criteria that will be compared are the systems’ functionality, the requirements that must be met to run the DBMS, the expansion capabilities – if it is able to expand to handle more data over time, the types of companies that typically use each one, the normal usage of the
how faults are detected. The logic name of the file should not be changed even when relocate the file. Client sends requests to handle files without thinking about the complex mechanisms of the underlying system which performs operations. The DFS server just provide an access to the system with some simple tools. DFSs also use local caching for frequently used files to eliminate network traffic and CPU consumption caused by repeated queries on the same file and represent a better performance. And

The addition of a simple, persistent, client-side state significantly extends the capabilities of Web-based client/server applications.”Kington, Andy, Andy’s HTTP Cookie Notes, Available from http://www.illuminatus.com/cookie_pages/ [modified 6
the same data from the bank servers. The ICC however can hold much more information and is much harder to copy or have data changed by criminals or hackers. The checkouts used in modern supermarket chains are all capable of EFT and are therefore all considered EFTPOS. In the next few years checkouts or ‘tills’ in all retail shops will use the ICC Barcodes The goods found in supermarkets are labelled with barcodes used to identify specific items on a central database. When the good is scanned a
central server. Napster pioneered the concept of peer-to-peer file sharing (P2P). With Napster, individual people stored files that they wanted to share (typically MP3 music files) on their hard discs and shared them directly with other people. Users ran a piece of Napster software that made this sharing possible. Each user machine became a mini server. By installing Napster software, your computer becomes a small server in the Napster universe. You can now contact the main Napster server for your
Unix box to accommodate the volume and processing demands your bean-counters have projected for you. You'd run Sun Microsystem's Solaris software on it to power your Web server and e-commerce applications. Or, you could opt to save a little venture capital and run Linus Torvalds' free operating system (and its accompanying free server apps) on a cluster of commodity Intel PCs. The Linux OS is well-suited to small- to medium-sized operations, and is increasingly being used in large enterprises that
through the internet with other users all over the world. Specifically, this is how Napster works: 1.) A user sends a request for a song. 2.) Napster checks its database of music to see if the song is on the PC hard-drive of another Napster user whose computer is turned on (Note: No music is stored on Napster servers). 3.) Napster finds the song. 4.) Napster sends the song in MP3 format to the user who requested On December 6, 1999 the record industry sued Napster in Federal
because the more users it attracts the more files other people can download. It as soon as you run napster your machine becomes a server to the internet with a shared folder able to be access by anyone else using napsters software. Napsters software then allows you to use a keyword based search to find files that you like and goes through the internet to find which other servers have files associated with your keyword. This type of file sharing is called Peer-to-Peer (P2P) file sharing. This program
multiprocessing units of this type are also referred to as “shared everything” systems. These systems usually do not exceed 16 processors. (Image courtesy of Sequent Manufacturing) The most common uses of these types of systems are commercial servers of web applications such used in on line commerce. The advantages of this particular configuration are that they can be easily upgraded by the addition of more processors. These processors are available to execute any of the given processes as soon
and composed of two campus sites. James Hargest College boasts a role of approximately two-thousand students and two-hundred staff members. Both grounds of James Hargest College have access to multiple network drives. A network drive, located on a server, is a storage device on a local area network (LAN) within a home or business. A network drive makes it easier to share documents, hardware, programmes and files within the LAN, between computers. When a student with a school account opens up ‘My
of databases most individual’s minds go to a relational database. Where data is stored in tables and they are inter-related to one another by the use of primary and foreign keys. The increased interest on big data has caused some companies to forgo the standard RDBMS in favor of a system that would better suit their needs. This is where NoSQL comes into play. NoSQL – or “Not Only SQL” – uses different data structures to house data. These structures could look similar to a relational database but
Planning Your Proxy Server Implementation A key factor in determining the success of any installation is planning. Planning involves several phases-from understanding your current capabilities, to determining your current needs, anticipating your future needs, and, ultimately, finding a viable solution. We have all been in situations where the immediate need surpassed the need for planning and the installation was rushed. More often than not, the installation had to be repeated to correct problems
amazing how one simple screen can provide everlasting opportunity for learning. One of the most widely used technologies is the Internet, or also known as the World Wide Web. “In August 1981 about 200 computers hosted Web servers. By July 1998 there were over 36 million Web servers, that are hosts to approximately 150 million people” (Strauss). The Internet proves to be very beneficial to education, since students have unlimited access to millions of websites with tons of information. There are only
The idea of multi-tenancy, or many tenants sharing resources, is a fundamental to cloud computing. It allows single instance of software to serve multiple organizations. SaaS requires sharing of application servers among multiple tenants for low operational costs. This paper discusses the concept of cloud computing in single tenant and multitenant environment. Multitenant applications are very useful for the increased utilization of hardware resources and improved ease of maintenance. Keywords:Cloud

It should be noted that this covers the entire Windows 2000 family (Server, Advanced Server, and Professional). • Improved Internal Architecture: Windows 2000 includes new features designed to protect your system, such as preventing new software installations from replacing essential system files or stopping applications from
Are We Too Dependent On Computers? Since the invention of computers in 1946, the lives of people around the word took a complete turnaround. Computers were invented to make life and work more efficient and effective. However, with the improvements and developments that have occurred in the communications and information industry, computers have part and parcel of people lives both at work and at home. Computers range from huge desktop mainframes, laptops, tablets to modern day mobile phones. Computers
It's this kinda email, database, group-think thing from IBM, right?" I hadn't heard it described exactly like that, but he was certainly in the ballpark. "But what the heck is Domino? Didn't Kim Basinger play Domino in Never Say Never Again? You're writing about a Bond girl?" I shook my head. Of course, he couldn't see that through the phone. "Uh, no Bob. We're not doing a journal on James Bond, as cool as that might seem. We're doing a journal on Lotus Domino, a very cool server technology, and on
