★ Has the ability to manage thousands of tasks at the same time ★ Allows multiple users to access the system simultaneously What is Linux? What is the Free Software Foundation/GNU? Which parts of the Linux operating system did each provide? Who else has helped build and refine this operating system? ★ Linux is an open source operating system based on UNIX.
Linux is different through user friendly OS and by GUI. 2. How can file permissions be used to establish system security? What effect does this have on the UNIX® or Linux® operating system? File permissions is used by allowing individual users and groups access to files based on a set of security settings for each file and directory.
However, switches filter data according to the MAC address. This can reduce congestion and decrease the collision domain (Ciccarelli, et al 2013). Switches support management capabilities and some provide built-in web servers for management over the Internet (Ciccarelli, et al 2013). Switches allow the network to be grouped into segments and can limit the amount of broadcast traffic that is propagated between segments (Ciccarelli, et al 2013). Because of their sophistication, switches can be more expensive, difficult to configure, and can increase the complexity of a network (Ciccarelli, et al 2013).
Describe how raid 1 works and its advantages/disadvantages? Page 110 Raid 1 advantage is if one disk fail , the data can be recover from the second disk. The disadvantage is by using this mirror, it only provides half as much storage space. 7. Which file system is most commonly used with Windows 7.
NT1430 Unit 2 Assignment 1 Chapter 5 The Linux Utilities 1. Which command can you use to determine who is logged in on a specific terminal? * The command you can use is the $ w as well as who, and finger command. 3. What Happens when you give the following commands if the file named done already exists?
Windows has a Virtual memory manager (VMM) and avoids allocating all the memory until it is absolutely necessary. Windows does prefetching, which is moving pages from the disk to the main memory before it is even needed. Pages that are not needed in the memory are stored into a system called Page file until further need. With the Linux operating system, the files are organized already into the hard drive. This will give speed to Linux and provide for faster
As history has shown, in software, this limitation, however ethical it may be, is close to useless in protecting the inventor. There are only so many basic inventions in software. The most notable ones are word processors, spreadsheets, databases, and the graphical user interface (GUI). This means that if you invent the first spreadsheet, the UI may be copyrighted and the particular implementation of the functions behind it can be protected. But, this does very little in protecting you against some other guys writing a spreadsheet which is more user friendly, calculates faster, and provides more functions, even though you were the inventor of the spreadsheet.
Also we know that more processes running on your computer will in general mean less CPU’s horsepower available for other tasks. This means you should first have a look at the running services on your computer and determine if they are really necessary. For example is it really necessary that your TomTomHOMEService used for ejecting TOMTOM devices runs automatically or can you may be set it’s start up type to manual in the Windows 7 in Control Panel > System and Security > Administrative Tools > Services list? A less obvious factor which can affect your computer’s performance is the fragmentation on the hard disk drive, making it more difficult for the system to build up the data it needs to run you applications in memory if the composite data are scattered all over the hard disk drive. In the System Section under the Control Panel in Windows 7 is a section called “Check the Windows Experience Index” which is a nice step up from the situation
This includes the default domain and the forest-wide DNS application partitions that are created on Windows Server 2003-and-later domain controllers. The Active Directory Installation Wizard performs the initial placement of roles on domain controllers. This placement is frequently correct for directories that have just a few domain controllers. In a directory that has many domain controllers, the default placement may not be the best match for your network. Think about this when trying to figure where the roles go, It's easier to keep track of FSMO roles if you host them on fewer computers.
Thousands of people helped refine the operating system online and freely. Chapter 2 1.) Briefly, what does the process of installing an OS such as Fedora/RHEL involve? Installing Fedora/RHEL is the process of copying operating system files from a CD, DVD, or USB flash drive to hard disk(s) on a system and setting up configuration files so Linux runs properly on the hardware. Several types of installations are possible.
