Computer System Computer Power Mac G4 The new Power Mac G4 is up to twice as fast as the fastest Pentium III-based PCs. With its Pentium-crushing speed and new design, the Power Mac G4 picks up where the old Macintosh (G3) left off. Its enclosure is now highly polished silver and graphite, yet it still offers easy access to every internal component through its swing-open side door. With PowerPC G4 with Velocity Engine, the computer speeds up to 450MHz, one megabyte of backside lev

Understanding Product Knowledge: When Purchasing a Computer Buying a computer seems like a daunting task to many. There are many factors to consider when making a purchase. Brand name, functionality, speed and customer support are just some of the factors that one must consider when researching the options. In order to wisely purchase a computer, one must attain a considerable amount of product knowledge, to get the most value for their dollar. Consumers have different levels of produ

The problem today is why the computer interface hasn t changed in the last thirty years. The problem with today s computer interface is the way it is laid out and manipulated. The interface of today still requires a desk and chair, giving an office atmosphere (Harmon). For today s users this reminds them of work, or in some cases, the interface can be cumbersome. The interface is very awkward on how it interacts with the human counterpart. Experts say that if we don t change the int

CPU Internal Organisations The input/output (I/O) interface, bus structures, microprocessor, memories and peripherals (also known as external or I/O devices) are the major components of a computer system. These components constantly trade information and instructions to complete assigned operations. With the exception of the peripherals, the ongoing communication between components is conducted within the system through interconnections or paths called buses. Peripherals such as keyboards, a

Client/server is the combination of three major technologies: Relational database management systems (RDBMSs), networks, and client interfaces. Clients execute specific local tasks with local resources. Servers provide shared resources and fulfill broad tasks. Communication enables definition and completion of full work processes. Client/Server software Infrastructure With competing paradigms-SQL databases, TP monitors, groupware, and distributed objects-the middleware that connect

Common Network Architectures There are many different types of networks used today that could be evaluated. I would like to take a brief look at three main types of networks, the host-based network, the client-based network, and the client-server network. I would like to look at both the advantages and disadvantages of each type. In the host-based network there is a host or server, often a mainframe computer that does virtually all of the work on the network. The host computer prov

The newest version of Transputer architectured chips is the INMOS T-9000, a processor containing 4 serial links, designed to be hooked up to other processors for parallel processing. The instruction set is minimized, as is the Sparc's RISC design, but is "based on a stack/accumulator design and designed around the OCCAM language". each chip containing 4 serial links to connect the chips in a network.The T-9000 was an attempt to regain the lead after more recent chips have surpassed prev

The era of the First Generation computers began around 1945 and ended around 1957. These Machines featured components such as vacuum tubes, drum memories and had to be programmed in machine code. (That is the 1's and 0's computers understand) The Second Generation computers began around 1957 and ended around 1963. These computers had components such as transistors instead of vacuum tubes, magnetic core memories and higher level programming languages called assembly code was introduced.

In an ideal world, it would be easy to deploy and manage the robust client/server applications that tap today s abundant PC power. But if you support a distributed computing environment built around the Wintel computing architecture, you know better. To a large extent, the culprit is a Microsoft OS deign that s not quite at home in the enterprise. While hundreds of add-on products promise to reduce cost of ownership though centralized desktop management, few deliver benefits that justify their

The operating system commonly used for distributed computing systems can be classified as (a)network operating system and (b) distributed operating system.A distributed OS must be designed with the assumption that c

Virtual Reality is considered one of the most exciting technologies today, constantly evolving and improving. According to Eric Drexler, a world known pioneer in this field, VR is "A combination of computer and interface devices (goggles, gloves, etc.) that present a user with the illusion of being in a three dimensional world of computer generated objects." The term ^virtual reality,^ is not finite in its meaning, but generally includes desktop VR, immersion VR, where the goggles and
