Hardware Interactions – 14 Pages 

Using the Internet, visit the site for a processor manufacturer (Intel or AMD). Research the design of their latest processor and discuss how they differ. Which one would you choose and why?

One thing about AMD they do not change there processor socket design as much as Intel.  This means if AMD releases a newer processor you have a greater chance of using it with your existing motherboard.  I’m glad AMD exists to keep the competition up and the prices down.  It normally makes me no difference between Intel and AMD; I normally go with the cheapest computer that meets my current needs. I have never built my own computer, and I really don’t game or use any programs that need superior computing powers…

Hardware Selection – 13 Pages

Using the Internet, research the task of building your own PC. Discuss the required and optional components. Discuss why you choose one brand over another.

Computers and motherboards come in all sorts of shapes and sizes, although most consumers have only seen a select few. The most common form factor in use for a typical consumer system is the ATX, created by Intel in the mid 90’s, and is used for the “typical” sized desktop PC. The Micro-ATX, a smaller variant of the ATX, is used mainly for “small factor” desktop PCs. The Mini-ATX is an even smaller subset of ATX, and is typically used with power-efficient, mobile grade CPUs. Mini-ITX is a very compact form used for set-top boxes and thin-clients. Finally, Nano-ITX is a smaller and more tightly integrated version of Mini-ITX used in automotive entertainment systems, cable boxes, and media center devices…

Operating System Functions – 11 Pages 

Discuss the four functions of the operating system and how Windows and Linux perform those functions. Explain the differences in each operating system and how they interact with the hardware. Discuss such things as polling, memory management, and resource management.

Some of the basic operating system functions include
Providing a user interface for the user to be able to interact with the computer.
Another function is to provide security for the user and the information stored in the computer. This storing in the computer can be done using passwords and other encryption methods.
The operating system takes care of multitasking by running a couple of programs without slowing down.
It also controls the devices plugged into the computer be it printers, keyboards and other devices…

Applications and Hardware Access – Posts 14 Pages 

Discuss how applications are able to access hardware resources. Explain how an application is able to work with the system memory to complete its task. What role does the operating system play in the interaction?

The OSI model has seven layers which are
Physical layer- it is concerned with receiving and transmitting raw bit communication
Data link layer- provides and error free transfer of data from one node to another over the physical layer
Network layer- provides the area for the transfer of data and here is where the decision is made on which data path to take based on the network conditions
Transport layer- this layer ensures that the messages are delivered error free
Session layer- allows session establishment between processes running on different stations
Presentation layer- Formats the data to be presented in the application layer
Application layer- provides a window for users to access network services…

Comparing Operating Systems – 11 Pages 

The Windows operating system continues to maintain a higher market share than other operating systems. Why do you think that the Windows operating system has been so successful? Why hasn’t the Mac or Linux operating system been as successful? What future changes can you predict for the Windows operating systems or any other systems?

Back in the days when PCs were first being mass produced and sold, Microsoft made deals with the PC manufacturers to install DOS and later Windows on each PC they sold. The manufacturers had to sign an agreement that they would sell on those systems, preinstalled, and that they would sell no system without it. They then provided the software to the companies at a very low quantity price. The manufacturer added the cost in the price of the computer.

This was how Microsoft guaranteed they get their crappy operating system on most of the world’s computers. Most people don’t object because most average users don’t want to monkey with the system, they just want it to work. And since everyone they know uses Windows as well, then all is right with the world.

The success of Windows has NOTHING to do with it’s quality as an OS. OS X, Linux and many other systems are far superior to Windows in every conceivable way. They just shoved it down everyone’s throats and everyone swallowed.

Macs are rapidly growing in popularity. But people and businesses like the cheapness of PCs and Windows.

Mac is more Stable because it is a “Closed” System controlled by Apple and the Hardware and Software is ONLY made by Apple…

Comparing Operating System Installation – 14 Pages 

This week’s iLab has you perform the installation of Windows 7 and Ubunto Linux. How does the installation process differ for each operating system? Discuss the pre-installation steps and minimum hardware requirements for each.

In the overall scheme of things, installing any of the three major OSes involve the same set of steps: acquiring OS, acquiring hardware, creating installation media, installing OS, and updating drivers.  Its the specific details pertaining to each OS that throw the proverbial wrench into the works. For example, all flavors of Linux are available for free on the Internet, the installation media can either be USB or DVD, and the average system requirements are: 1GHz processor, 800mb RAM, and 5gb hard drive space. Drivers for Linux machines are usually updated using the “sudo apt-get update” command in the terminal. For OSX, the OS is available for free for users who have Lion or above, the installation media can be both USB and DVD, and the average system requirements are: 2.4GHz 64-bit processor, 2GB RAM, and 8GB hard drive space. Drivers can be updated using the App Store. Finally, for Windows, the OS is available for free online, but the licenses must be purchased. The installation media can be both USB and DVD, the minimum system requirements are: 1GHz processor, 1GB RAM for 32-bit and 2GB RAM for 64-bit, and 16GB hard drive space for 32-bit and 32GB hard drive space for 64-bit. The drivers can be updated using the “Check for Updates” utility…

Storage Media – 16 Pages 

There are many different types of storage media available for use with computer hardware, both internally and externally. Using the Internet, select two different types of storage media (preferably an internal and external), and then visit the manufacturers of those devices. Discuss the technology used by the device to interface with the computer.  Is EIDE becoming obsolete, or is there a future for it?

Outside of interfacing with proprietary and/or obsolete technologies, EIDE has steadily lost its usefulness within the field of computer science. SATA is a significant improvement over the EIDE interface. The SATA pins and cables are physically smaller than EIDE, and SATA supports more storage capacity and higher data transfer rates than EIDE. In my opinion, EIDE is going to be obsolete very soon, save for a few niche cases. SATA has already fallen to comparable price to EIDE in terms of implementation, and as a result, is showing up in higher numbers in consumer devices.

EDIT: The game changing advantage that SATA has over EIDE is that the peripherals connected via SATA have the ability to be hot swapped during usage…

Maintenance Plan – 40 Pages 

As part of any computer maintenance plan, we plan for the protection of our data. List and discuss the primary threats to computer systems. Review the basic components of a disaster plan, also referred to as a continuity of operations plan (COOP) that you would create to survive those threats. Discuss why it is a necessity for organizations to have these plans and the role storage technology plays in disaster planning.  Describe several methods for preventing and/or managing the spread of computer viruses.

The obvious things would be to not visit any fishy websites, click on popups, and not plugging in unknown devices into the computer. Other than that, having a good anti-virus and anti-malware program on the PC is a must, and running routine scans will also be beneficial. To prevent the spread of computer viruses, if the infected PC is in some kind of a local network, it must be isolated immediately and be disconnected from the network…

Directory Commands – 11 Pages 

Compare the tasks of copying, moving, renaming, and deleting files and directories from the command-line and from a GUI, using Windows and Linux. Why do we have both utilities available in each OS? Does one OS provide a better CLI than the other?  What is the purpose of supporting two directory display commands in DOS? Which command is more useful, TREE or DIR?

The TREE command graphically displays directory path of a path or a disk in the computer’s drive. For example, typing in tree command while in the C: drive would recursively give you all of the folders and sub-folders within the C: drive. The DIR command, on the other hand, non-recursively does the same thing. For example, typing the dir command within the C: drive would just give you the files and folders within the parent folder of the drive, not for any of the sub-folders. As far as the usefulness, it depends on what the user is looking for. I personally like the TREE command more than the DIR command because having a map of where everything in my computer is more important to me than what the contents if each individual folder is…

Files and File Security – 12 Pages 

Focus on how each operating system uses file security. Discuss the differences in the Linux file system as compared to Windows NTFS. Do you think that one is better than the other; if so, why? Please be sure to discuss both operational and security advantages/disadvantages of both file systems.  How does knowledge of common file types improve your ability to work with applications?

Knowledge of common file types is important because that knowledge allows you to effectively share documents and other files with a wide group of people with ease. For example, saving a text document in the .doc file type would allow you to share that file with people who use the latest version of the Office Suite, older versions of the Office Suite, Pages in OSX, and the LibreOffice Suite in Linux. All of these people would be able to open and edit the file with no corruptions and little to no formatting errors…

Text Editors – 10 Pages 

Compare how the following operations are performed in DOS Edit and Vim: highlighting, cutting, copying, and pasting. With respect to these operations, which editor is easier to use? Which editor is more flexible?  Why is it important to learn how to manipulate DOS Edit without a mouse?

MS-DOS is not a graphical user interface; it’s command line. As such, mice are not available as input devices. All navigation is designed to be done via the keyboard, and should be done as such. Also, all directories, files, menus and sub-menus are made to be easily accessible via the keyboard in the command line user interface…

Scripting – 10 Pages 

Discuss how Windows and Linux perform scripting. Is there a difference? Why is a script file considered to be a kind of program? We use text editors instead of word processors, such as MS Word, for creating and modifying system configuration and source code files. Provide several reasons for this preference.  What are the benefits of learning to interact with your PC via the CLI?

The advantages of CLI over a GUI range in variety from cost effectiveness to usage requirements. For example, an OS that uses CLI doesn’t require a very powerful processor, high capacity and high speed RAM, or a high quality and high resolution display. The code needed for operations in a CLI is much simpler than in a GUI. A CLI allows for efficient scripting of tasks. Most importantly, a CLI gives the user a level of control that is not replicable by any GUI…

Operating System Maintenance – 11 Pages 

Suppose you have observed that your system is performing slower than usual. Applications are taking longer to load; switching among tasks is also taking longer and may even cause some applications to crash. Which system resources are likely to be at the root of the problem? Discuss how you can use system tools, such as the Task Manager, to help identify and troubleshoot these problems.  Why is it important to learn the various signals associated with the kill command?

The signals associated with the various kill commands in both Windows and Linux allow the user a high degree of control over how the kill command is implemented and what processes and applications are affected by the kill command. The three types of kill commands in Linux are: killall which kills all processes with a user-defined name, pkill which performs similarly to killall but with partial names, and xkill which allows the user to kill a program by clicking on the graphical window. The various types of signals for these allow the user to kill just a particular process, the whole program or application, or initiate a core dump. Also, there are some kill signals that can be user defined…

Home Networking – 12 Pages

Suppose you wanted to setup a home network, what are some of the security issues you would be concerned with, and how would you protect your computer? Discuss the different steps you would take to protect your computer and home network from malicious attacks.  What are the main benefits of computer networks?

Computer networks allow for the vast exchange of information between geographically distant locations. The distances can be as small as two rooms located within the same building, or as large as the antipodes of the Earth or even between the Earth and outer space.
