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. -

Implementing Hard Drives 10
All-in-1 / A+ Certification Exm Gde, 6th Ed. / Meyers / 6311-3 CHAPTER Implementing Hard Drives 10 In this chapter, you will learn how to • Explain the partitions available in Windows • Discuss the formatting options • Partition and format hard drives • Maintain and troubleshoot a hard drive From the standpoint of your PC, a new hard drive successfully installed is nothing more than a huge pile of sectors. CMOS sees the drive; it shows up in your autodetect screen and BIOS knows how to talk to the drive; but as far as an operating system is concerned, that drive is unreadable. Your operating system must organize that big pile of sectors so you can create two things: folders and files. This chapter covers that process. Historical/Conceptual After you’ve successfully installed a hard drive, you must perform two more steps to translate a drive’s geometry and circuits into something usable to the system: partition- ing and formatting. Partitioning is the process of electronically subdividing the physical hard drive into groups of cylinders called partitions (or volumes). A hard drive must have at least one partition, and you can create multiple partitions on a single hard drive if you wish. In Windows, each of these partitions typically is assigned a drive letter such as C: or D:. After partitioning, you must format the drive. This step installs a file system onto the drive that organizes each partition in such a way that the operating system can store files and folders on the drive. Several different types of file systems are used in the Windows world. -

Security Now! Transcript of Episode #800 Page 1 of 27 Transcript of Episode #800 SolarBlizzard Description: This week we open the New Year taking a longer look at fewer topics since the bad guys were apparently enjoying their New Year holiday, too. So we look at an interesting kludge that's been forced upon Chrome by ill-mannered antiviral scanners. We need to warn all enterprise users of Zyxel network border security products of another recently discovered built-in backdoor. We look at the rise in IoT compromise swatting attacks and a series of new flaws and vulnerabilities in the PHP Zend and Yii frameworks. We have a quick bit of miscellany to share, then I want to explain a lot about the value of trimming SSDs and newer SMR drives. And we'll conclude by catching up with what will hopefully be the last news, for a while at least, of the disastrous SolarWinds breach and intrusions.

Steve Gibson is here with a defunct football; a very bad AV security practice that Chrome has had to do something maybe even worse to fix. We'll talk about the built-in password access in 100,000 Zyxel firewalls, VPN gateways, and access point controllers; an update on SpinRite 6.1; and a whole lot more. Security Now! is coming up next. -

The following excerpt of Q & A from http://www.freedos.org will help you to understand what FreeDOS is all about. Please note that you have access to these Q & A from FreeDOS official website, http://www.freedos.org but they are provided here for convenience. • What is FreeDOS? FreeDOS is a free DOS-compatible operating system that can be used to play games, run legacy software, or support embedded systems. FreeDOS is basically like the old MS-DOS, but better! For example, FreeDOS lets you access FAT32 file systems and use large disk support (LBA) — a feature not available in MS-DOS, and only included in Windows 95 and newer. • Is FreeDOS really free? Yes, FreeDOS is really free. It doesn't cost anything to download and run FreeDOS. Even better, FreeDOS is open source software; you can view and edit our source code. All FreeDOS programs are distributed under the GNU General Public License ("GNU GPL") or a similar open source license. Because we are open source software, anyone can contribute to it. Even if you don't write code, you can help out the FreeDOS Project by reporting bugs . -
Usability Themes in Open Source Software
Usability Themes in Open Source Software Jim Hall University of Minnesota (Dr. Ann Hill Duin, advisor) April 30, 2014 1 ABSTRACT This research examines the prevalent state of usability in open source software, focusing on the reasons why usability is often overlooked in the open source software noosphere. A usability test of GNOME, a popular open source software desktop environment, provides insights into the present development structure, and highlights areas for improvement. Analysis of the test data suggests features or themes of usability, and provides avenues of exploration to improve overall usability within open source software systems. 2 A program should follow the `Law of Least Astonishment.' What is this law? It is simply that the program should always respond to the user in the way that astonishes him the least. The Tao of Programming (pp. 55-57) Geoffrey James Open source software developers create an array of innovative programs: WordPress is the world's most popular blogging platform, used by a staggering 202 million websites ¼ Magento, used by 30,000 merchants, including Samsung, Nespresso and The North Face, is the world's fastest growing e-commerce platform ¼ Firefox currently accounts for 24.43% of the recorded usage share of web browsers, but this figure is on the rise ¼ GnuCash provides a great, free alternative to paid-for accounting software ¼ Music software like Cubase and Logic Pro can be incredibly expensive, which is why an increasing number of people are turning to Audacity, a free, cross-platform sound editor
