Out of the 1700 servers tested more than 60% could be broken into and tampered with, meaning data changed, or even distroyed (Intranet Security 22). Even the ...
- 11982: Computer Science
- ... and developing algorithms that make more effective use of the computer's time and memory. The study of numerical computation involves the development of algorithms for calculations, often on large sets of data or with high precision. Because many of these computations may take days or months to execute, computer scientists are interested in making the calculations as efficient as possible. They also explore ways to increase the numerical precision of ...
- 11983: Object-Oriented Database Management Systems
- ... the OODBMS can provide a special query language as the RDBMSs did, a specially extended programming language, or some graphical tools (browsers, forms, etc.). Whatever they do provide should satisfy the following: it should be high- level so that the queries will be simple and easily understood by humans, it should be efficient, and it should be application independent. In this section I will analyze the optional features that an OODBMS ...

- ... is supposedly due in '97 when hardware vendors will have had a chance to write new drivers. Power Management is not available either in 4.0. Early reports of its installation on Notebooks report a high crash rate and slow recognition of cards and links to docking stations. Multimedia support will be very limited. This will mean that Win95 will be the main platform for multimedia (and games). Object linking 2 ...

- 11987: What is A Robot
- ... used to maintain the linear accelerator, or "atom smasher", at the Los Alamos Meson Physic Facility in New Mexico. When protons are accelerated, strong radioactivity occurs. Even if the machine is off, radiation is still high and hazardous to humans. Workers use the manipulators to maintain the target area. The arms hang over the area from a large hydraulic system. The operators, which are sitting behind a protective wall, move the ...
- 11988: BBS Piracy And The Copyright
- ... and still bringing up more technological advancements. The companies, in one sense , have outsmarted and beaten the pirates. From BBS's, users have to opportunity to view software and evaluate it before they pay the high cost of the extras. Programmers also have the opportunity to view other works and learn from the advancements, or find the errors in the beta (or commercial) versions. Like all laws, The Canadian Copyright Act ...
- 11989: Computers in Math
- ... Arithmetic and Logical unit helps the computer solve some of these problems. All type of math can be solved on computer's which it uses. Binary Arithmetic A computer understands two states: on and off, high and low, and so on. Complex instructions can be written as a combination of these two states. To represent these two conditions mathematically, we can use the digits 1 and 0. Some simple mathematical operations ...
- 11990: New Eye Tracking Techniques Improve Realism of Aircraft Simulators
- ... Further, it would take an enormous amount of addi to improve image quality significantly throughout the whole viewed scene. However, based on the visual properties of the eye, realism can be obtained by providing a high-resolution 'area of interest' insert within a large, low-resolution field of view. If the image-generating computer 'knows' where the pilot's fixation is, it mage there. The technology to make this possible was ...
