Journaling requires more writes to the storage unit and can be slow on these external devices. The Flash and USB drives have a limited number of write cycles. The Filesystem Hierarchy Standard (FHS) is a reference describing the conventions used for the layout of a UNIX system. It has been made popular by its use in Linux distributions, but it is used by other UNIX variants as well. The Linux Standard Base (LSB) refers to it as a standard.
People would utilize this one more because if one disk would fail, the mirror image of that disk will be on another disk. 6. I would personally choose 0 due to the increase in the speed. 7. The hardware-based system manages the RAID subsystem independently from the host and presents to the host only a single disk per RAID array.
3/28/2013 NT1430 Unit 1 Chapter Exercises Chapter 1 Q1. – Free software is software that is available for anyone to use and modify however they like. 3 characteristics of free software are that, you are free to study, redistribute, and modify it free of cost. Q2. - Linux is so popular because it’s free, you can make any changes to it for the most part hassle free, it a very advanced (sometimes more) and usually better than software you pay for.
Chapter 7 Solutions Lab 7.1 Why might you want to upgrade RAM on a system? Answer: It would improve performance. How many pins are on the different types of DIMMs? Answer: 168, 184, or 240 although SO-DIMMs (used in laptops) have different configurations Which is more expensive: DDR-DIMM or RIMM? Answer: RIMM of the same MB What is a disadvantage of using two 512 MB modules instead of a single 1 GB module in a system with three slots for memory modules?
* When it comes to large USB flash drives, the FAT32 file system is the intended primarily used. The reason that FAT is used is because FAT can be used on both operating systems, Windows and iOS, and NFTS cannot be used on non-window systems. * Which file system provides support for larger hard drives and better security in the form of encryption and permissions that restrict access by unauthorized users? NFTS is the required file system for large hard drives, because you are able to give it better security than the FAT. With FAT and if you are using Windows 7 then your files can be read unlike the NTFS.
List and describe in detail four advantages of Linux. The four advantages of Linux include: a) Affordability, Linux has open source software,meaning that there are no license fees. b) Portability, Linux is a generic operating system that can run on different types of operating systems from different companies. c) Security because it is logical based and everything is file based. d) Multiple users, it can run multiple tasks with many different users at the same time.
UNIT 1 ASSIGNMENT 1 1) R.A.M- Stands for (random access memory). This is a type of computer memory that can be accessed randomly. RAM is the most common type of memory found in computers and other devices. 2) O.S.-(operating system) is a collection of software that manages computer hardware resources and provides common services for computer programs. The operating system is an essential component of the system software in a computer system.
2. Documentation folder contains three files which will guide you through software installation steps, project creation and loading program. 3. Experiment_ATMEL-Studio-6 folder contains master code written in ATMEL STUDIO IDE. These codes are for reference and can be used by teams to understand the programming logic.
The operating system loads itself into memory and begins managing the resources available on the computer. It then provides those resources to other applications that the user wants to execute. * A task scheduler * A memory manager * A disk manager * A network manager * Other I/O services manager * Security manager The Linux kernel, created by Linus Torvalds, was made available to the world for free. Because it is free and runs on PC platforms, it gained a sizeable audience among hard-core developers very quickly. Linux has a dedicated following and appeals to several different kinds of people: * People who already know UNIX and want to run it on PC-type hardware * People who want to experiment with operating system principles * People who need or want a great deal of control over their operating system * People who have personal problems with Microsoft * In general, Linux is harder to manage than something like Windows, but offers more flexibility and configuration options.
