Optimizing and Protecting Hard Drives ‐ Chapter # 9
Optimizing and Protecting Hard Drives ‐ Chapter # 9 Amy Hissom Key Terms antivirus (AV) software — Utility programs that prevent infection or scan a system to detect and remove viruses. McAfee Associates’ VirusScan and Norton AntiVirus are two popular AV packages. backup — An extra copy of a file, used in the event that the original becomes damaged or destroyed. boot sector virus — An infectious program that can replace the boot program with a modified, infected version of the boot command utilities, often causing boot and data retrieval problems. buffer — A temporary memory area where data is kept before being written to a hard drive or sent to a printer, thus reducing the number of writes to the devices. chain — A group of clusters used to hold a single file. child, parent, grandparent backup method — A plan for backing up and reusing tapes or removable disks by rotating them each day (child), week (parent), and month (grandparent). cross-linked clusters — Errors caused when more than one file points to a cluster, and the files appear to share the same disk space, according to the file allocation table. defragment — To “optimize” or rewrite a file to a disk in one contiguous chain of clusters, thus speeding up data retrieval. differential backup — Backup method that backs up only files that have changed or have been created since the last full backup. When recovering data, only two backups are needed: the full backup and the last differential backup. disk cache — A method whereby recently retrieved data and adjacent data are read into memory in advance, anticipating the next CPU request. -

SWEDIN WEBER STATE UNIVERSITY DAVIS ABSTRACT In 2006, IBM ended their support of OS/2, closing the book on an ambitious effort to create a modern operating system for the personal computer. IBM and Microsoft released the OS/2 operating system in December 1987 to replace the primitive DOS with a more sophisticated, preemptive multitasking operating system for personal computers. This article argues that OS/2 failed because of the U.S.-Japan Semiconductor Trade Agreement of 1986, subsequent accusations of DRAM chip dumping by the United States, and the resulting tariffs on Japanese memory chips, led to a memory chip shortage that drove up memory prices. -
Installation and Performance
Installation and Performance Welcome Thank you for purchasing Visual Reality software. Visual Reality is designed to offer an easy but extremely powerful, three dimensional environment in which full color still images and 3D animations can be created. Visual Reality 2.0 includes: Renderize Live. Load 2D and 3D models from a variety of drawing and modeling programs or drag and drop from Visual Model and Visual Font and compose unique scenes in an intuitive 3D environment using a wide variety of material, lighting and camera effects. Load bitmap images from a variety of common file formats for backgrounds in scenes and as color, bump or reflection maps in material definitions. Render your compositions as full-color photorealistic images at any resolution. Animate just about anything with just a few button clicks. Objects, camera views, color intensity and location of lights and the bump height of materials can all be set in motion or transformed. Rotoscoping allows you to create moving water and flickering fire. Bend, twist, stretch and morph objects over time. An advanced channel editor gives you precise time line control of every attribute, for every element or object. The 'Ease to' and 'Ease from' functions and hierarchical linking of objects give your animations a natural feel with smooth, fully controllable motion. Visual Font. Load Windows TrueType fonts and create 3D text objects by defining extrusion and bevel properties. Load extruded text into Renderize Live for inclusion in 3D scenes. Visual Image. Load and modify bitmap images from a wide variety of file formats. Work on individual images, or use the powerful layering tools to create digital collages. -
Accessing Windows Applications from Unix and Vice Versa
50-20-42 DATA COMMUNICATIONS MANAGEMENT ACCESSING WINDOWS APPLICATIONS FROM UNIX AND VICE VERSA Raj Rajagopal INSIDE Accessing Windows Applications from an X-Station, Coexistence Options, Windows in an X-Station, Accessing Windows Applications, Accessing UNIX Applications from Windows Desktops, Emulators Migrating from one environment to another takes planning, resources and, most importantly, time (except in very trivial cases). This implies that even if eventually migrating to another environment, one still has to deal with coexistence among environments in the interim. In many com- panies it would make good business sense not to migrate legacy systems at all. Instead, it may be better to develop new systems in the desired en- vironment and phase out the legacy applications. The data created by the legacy applications is important and one must ensure that data can be ac- cessed from a new environment. Coexistence considerations are very im- portant in this case. Coexistence between Windows PAYOFF IDEA NT, UNIX, and NetWare deals with a Some users want applications they develop in number of related issues.

CRUSADER: NO REMORSE ™ INSTALL GUIDE Welcome to Crusader: No Remorse. This guide includes quick installation instructions for users more familiar with the process, and a detailed, step-by- step guide to installing the game. If you experience any difficulty, consult Troubleshooting (page 9). To avoid compatibility or memory problems, please take a moment to confirm that your machine matches the System Require- ments described on page 2. Remember, you may safely stop at any time during installation and return to DOS with q, except when files are being copied. QUICK INSTALLATION Note: If you are running a disk cache such as SMARTDrive, you need to disable it to ensure a clean installation. (This only affects the installation of the game. SMARTDrive will work normally during gameplay.) Refer to your SMARTDrive documentation or make a system boot disk as described in Boot Disks (page 4) to disable this cache. 1. Turn on your computer and wait for the DOS prompt. -
