EXERCISE 2 OPERATING SYSTEMS 1. What Operating EXERCISE 2 OPERATING SYSTEMS 1. What operating system you have installed on your home computer? What about school? At school: MAX 7.5 (a GNU/LINUX Distribution) and a virtual machine of WINDOWS 7 2. Write at least the name of 5 different operating systems. DOS - Disk Operating System - one of the first operating systems for the personal computer. (It was not very "user friendly" ) Windows - The Windows operating system, a product of Microsoft, is a GUI (graphical user interface) operating system. This type of "user friendly" operating system is said to have WIMP features: o Windows o Icons o Menus o Pointing device (mouse) MacOS - Macintosh, a product of Apple, has its own operating system with a GUI and WIMP features. Unix - Linux (the PC version of Unix) - Unix and Linux were originally created with a command-line interface, but recently have added GUI enhancements. Android is a mobile operating system (OS) currently developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets. 3. Explain why Microsoft operating system is called Windows. Microsoft works on the first version of a new operating system. Interface Manager is the code name and is considered as the final name, but Windows prevails because it best describes the boxes or computing “windows” that are fundamental to the new system. Windows is announced in 1983, but it takes a while to develop. Skeptics call it “vaporware.” On November 20, 1985, two years after the initial announcement, Microsoft ships Windows 1.0. Now, rather than typing MS-DOS commands, you just move a mouse to point and click your way through screens, or “windows.” Bill Gates says, “It is unique software designed for the serious PC user.” 3. Indicate the 4 freedoms of free software. When you speak about Free Software, you speak about freedom. And more precisely, about the four freedoms to use, study, share and improve the software. Thanks to an analogy to a recipe, it becomes quite clear how these freedoms work and why it is important that the source code of a program is available to everyone. 4. Why do you think Windows so strongly dominates the market for PC operating systems? Microsoft currently has around 90 percent share of the client operating system market with Windows, and while its dominance of the desktop client OS market is expected to continue. I think it is due to the following: 1) Historically Apple developing its operating systems at the same time with high-quality hardware equipment of course but they are extremely expensive ,especially if the desktop versions comparison between Mac and PC. Now can cost three times a Mac than a PC Windows. Besides Asians have flooded the world with a huge amount of their Pc low price to the number seems small quantity of Macs especially in third world markets. 2) Availability of applications and games is much greater in Windows so most opt for this option. 3) Marketing strategies that allowed Windows is perceived as a system for all users while Mac OS X is seen as a system that is used by specialists mainly from graphic design and GNU Linux perceived as a system for programmers or computer experts 4) Microsoft corporate maneuvers that force many manufacturers have to produce only Windows compatible hardware. 5) Corporate maneuvers to prevent the administration of the states adopt other operating systems 5. Enter statcounter page, http://gs.statcounter.com/ and find the use of operating systems for mobile phones in Spain. Collect the data. Compare to Europe (also copy data) and explains the reasons why you think there is that difference exist. 6. Try to find what “Disk partitioning” is. Which is the difference with the “Drive letter assignment”? Capture an image of your computer partitioning. In personal computers, a partition is a logical division of a hard disk created so that you can have different operating systems on the same hard disk or to create the appearance of having separate hard drives for file management, multiple users, or other purposes. For example, when you install an operating system like Windows, part of the process is to define a partition on the hard drive. This partition serves to define an area of the hard drive that Windows can use to install all of its files. In Windows operating systems, this primary partition is usually assigned the drive letter of "C". In addition to the C drive, Windows often automatically builds other partitions during installation, even though they rarely get a drive letter. The drive letter assignment is the process of assigning alphabetical identifiers to volumes. Unlike the concept of UNIX mount points, where volumes are named and located arbitrarily in a single hierarchical namespace, drive letter assignment allows multiple highest-level namespaces. Drive letter assignment is thus a process of using letters to name the roots of the "forest" representing the file system; each volume holds an independent "tree". .

    Design of the FAT file system A FAT file system is a specific type of computer file system architecture and FAT a family of industry-standard file systems utilizing it. Developer(s) Microsoft, SCP, IBM, [3] The FAT file system is a legacy file system which is simple and robust. It Compaq, Digital offers good performance even in very light-weight implementations, but Research, Novell, cannot deliver the same performance, reliability and scalability as some Caldera modern file systems. It is, however, supported for compatibility reasons by Full name File Allocation Table: nearly all currently developed operating systems for personal computers and FAT12 (12- many home computers, mobile devices and embedded systems, and thus is a bit version), well suited format for data exchange between computers and devices of almost FAT16 (16- any type and age from 1981 through the present. bit versions), Originally designed in 1977 for use on floppy disks, FAT was soon adapted and FAT32 (32-bit version used almost universally on hard disks throughout the DOS and Windows 9x with 28 bits used), eras for two decades. Today, FAT file systems are still commonly found on exFAT (64- floppy disks, USB sticks, flash and other solid-state memory cards and bit versions) modules, and many portable and embedded devices. DCF implements FAT as Introduced 1977 (Standalone the standard file system for digital cameras since 1998.[4] FAT is also utilized Disk BASIC-80) for the EFI system partition (partition type 0xEF) in the boot stage of EFI- FAT12: August 1980 compliant computers.

  • Using Windows NT 4.0 Driver
    _________________________________________________________________________________________________ Using Windows NT 4.0 Driver IBM’s Windows NT 4.0 driver makes Memory Key the only USB-compliant storage device that can be used in a Windows NT environment. Windows NT completes the Windows operating system portfolio that supports Memory Key. The NT 4.0 driver is compatible with both servers and workstations, and can be targeted for multiple markets to support both corporate and personal use. Built-in, quick start procedures guide you through installation step by step. This text summarizes these procedures, and also includes some troubleshooting procedures. 1 ESSENTIAL GUIDELINES FOR USING YOUR MEMORY KEY WITH WINDOWS NT The Universal Serial Bus (USB) is designed to make it easy to connect various devices to your computer. The USB is fully plug and play, which means you can plug USB devices into your computer while it is running. By default, Windows NT does not support the USB interface. Neither does Windows NT support the plug and play standard. M-Systems’ Memory Key NT driver enables Windows NT to support the USB interface. It also adds limited plug and play functionality for Memory Key by creating a virtual disk device during installation (similar to floppy disk or CD ROM behavior). This virtual drive is inaccessible until you insert your Memory Key, and it remains intact until the NT driver is uninstalled. You can insert up to two Memory Keys on the same machine that is running Windows NT. However, because Windows NT does not automatically provide this support, it is critical that you follow the guidelines below when using your Memory Key in a Windows NT environment: Do’s • CAUTION! To prevent data loss, always wait at least 5 seconds after the LED on the Memory Key stops flashing rapidly before removing it from your computer.

  • File Allocation Table - Wikipedia, the Free Encyclopedia Page 1 of 22
    File Allocation Table - Wikipedia, the free encyclopedia Page 1 of 22 File Allocation Table From Wikipedia, the free encyclopedia File Allocation Table (FAT) is a file system developed by Microsoft for MS-DOS and is the primary file system for consumer versions of Microsoft Windows up to and including Windows Me. FAT as it applies to flexible/floppy and optical disc cartridges (FAT12 and FAT16 without long filename support) has been standardized as ECMA-107 and ISO/IEC 9293. The file system is partially patented. The FAT file system is relatively uncomplicated, and is supported by virtually all existing operating systems for personal computers. This ubiquity makes it an ideal format for floppy disks and solid-state memory cards, and a convenient way of sharing data between disparate operating systems installed on the same computer (a dual boot environment). The most common implementations have a serious drawback in that when files are deleted and new files written to the media, directory fragments tend to become scattered over the entire disk, making reading and writing a slow process. Defragmentation is one solution to this, but is often a lengthy process in itself and has to be performed regularly to keep the FAT file system clean. Defragmentation should not be performed on solid-state memory cards since they wear down eventually. Contents 1 History 1.1 FAT12 1.2 Directories 1.3 Initial FAT16 1.4 Extended partition and logical drives 1.5 Final FAT16 1.6 Long File Names (VFAT, LFNs) 1.7 FAT32 1.8 Fragmentation 1.9 Third party

  • Hard Drive Backup with Largest Capacity Removable Disks
    RAIDFrame® High-Rely RAIDFrame(R) Backup System Documentation V1.5 1 Copyright 2007-2011 by Highly Reliable Systems, Inc. All rights reserved. READ THIS FIRST Important Quick Start Information for your RAIDFrame(R) ● DO NOT ATTEMPT TO REMOVE RAIDFrame(R) media (RAIDPacs) from their drive bays without pressing the “release lever” on the drive slot first! Forced removal of the drive will void your warranty and damage the mechanism. ● RAIDPacs will not “power up” until they are fully inserted and the release lever is in the locked position. ● WE HIGHLY RECOMMEND that the RAIDFrame(R) is placed on a UPS of 1000VA capacity or better. This will insure stable operation and product life during unstable power situations. ● The latest Service Packs are important! Microsoft has continued to Debug removable drives on the Windows product lines. ● Not all eSATA ports are created equal. We recommend HBA controllers which support Port Multiplier and Hot-Swap capabilities such as those based on the Silicon Image chip sets for maximum compatibility. Other eSATA ports may only recognize the first drive in a multi-drive system or may not function at all. ● If you have more RAIDPacs then you have bays, you WILL have a drive letter problem as you change your media. Windows will assign drive letters randomly, which can confuse your backup software. You can use the High-Rely Drive Manager utility HRDM2.MSI to solve this problem. To do this, install HRDM2 on the machine that the RAIDFrame(R) system will be connected to. See “Understanding the High-Rely Drive Manager” in this manual for more information.
