Command line vs. GUI.

Answers

 Users not completely familiar with a command line interface or a graphic user interface may want to know the advantages and disadvantages of each interface to determine which one is best for them or help become more familiar with interfaces and what is best to use and why. Below is a table to help illustrate the major advantages and disadvantages of each of the interfaces.

Topic	Command line	GUI
Ease	Because of the memorization and familiarity needed to operate a command line interface new users find it much more difficult to successfully navigate and operate a command line interface.	Although new users may have a difficult at time learning to use the mouse to operate and use a GUI most users pick up this interface much easier when compared to a command line interface.
Control	Users have much more control of their file system and operating system in a command line interface. For example, users can easily copy a specific file from one location to another with a one-line command.	Although a GUI offers plenty of control of a file system and operating system often advance users or users who need to do specific task may need to resort to a command line to complete that task.
Multitasking	Although many command line environments are capable of multitasking they do not offer the same ease and ability to view multiple things at once on one screen.	GUI users have windows that enable a user to easily view, control, and manipulate multiple things at once and is commonly much faster to do when compared to a command line.
Speed	Because command line users only need to use their keyboards to navigate a command line interface and often only need to execute a few lines to perform a task an advanced command line interface user would be able to get something done faster then an advance GUI user.	A GUI may be easier to use because of the mouse. However, using a mouse and keyboard to navigate and control your operating system for many things is going to be much slower than someone who is working in a command line..
Low resources	A computer that is only using the command line takes a lot less of the computers resources.	A GUI will require a lot more system resources because of each of the elements that need to be loaded such as icons, fonts, etc. In addition video drivers, mouse drivers, and other drivers that need to be loaded will also take additional resources.
Scripting	A command line interface enables a user to easily script a sequence of commands to perform a task or execute a program.	Although A GUI enables a user to create shortcuts, tasks, or other similar actions to complete a task or run a program it doesn't even come close in comparison to what is available through a command line.
Remote access	Often when accessing another computer or networking device over a network a user will only be able to manipulate the device or its files using a command line, CLI, or other text only manipulation.	Although remote graphical access is becoming popular and is possible. Not all computers and especially not all network equipment will have this ability.

MAC Vs PC

Answer

This is one of the most controversial topics when talking about computers. This document is meant to give a comparison between Apple Macintosh computers and PC computers running Microsoft Windows. This page should be used to help educate users looking to buy a new computer and not as a method of declaring the best of the two. You should base your buying decision off what you believe will work best for you.

Topic	Mac	PC
Security	When compared to any PC running Microsoft Windows all Apple Macintosh computers are much more secure and less vulnerable to viruses and other malware.	The majority of people using computers today are running some version of Microsoft Windows and therefore most attackers target these computers and users first.
Price	Although many may argue you get what you pay for, when compared to a PC an Apple computer and its peripherals are often much more than a PC.	The vast majority of PC computers and their peripherals today are much cheaper and affordable when compared to a new Apple Macintosh computer.
Operating System	The Apple Macintosh operating system is a much cleaner and stable operating system than all versions of Microsoft Windows, especially a new PC bundled with the manufactures software and drivers.	Although Microsoft has improved its operating system with Windows 7 many PC manufacturers keep their prices low by bundling crapware with the computers. With this software and drivers made by dozens of different manufacturers the Windows Operating System can be less stable than the Mac.
Software	Although the available software options for an Apple computer is increasing it's still nothing when compared to the software available for Windows computers. However, with Boot Camp an Apple user could still run Windows and many of its programs.	More people are using and developing for PC computers running Microsoft Windows and therefore it has a much larger selection. In addition there is an almost endless supply of 100% free programs available today for the PC.
Quality	The Apple Macintosh computers are often built with a lot better materials when compared with most PC computers.	To help keep the overall costs low many PC manufacturers will build their computers from plastics and other cheaper materials when compared to a Mac.
Options	When compared to a PC an Apple Macintosh has much less options for customization.	PC computers are available in almost any imaginable configuration, color, size, etc. If you can think of something that's not available it's likely someone could still build it for you.
Boot time	The boot time on an Apple Macintosh can be a lot less when compared to a Windows computer.	PC computers have an operating system that is designed by Microsoft and hardware that's designed by dozens of different companies. Because of this and other factors the boot time can be greater than a Mac.
Upgrades	Although many of the most commonly upgraded parts in a Macintosh can be upgraded, not everything is as easily upgradable as it is with a PC. In addition those parts that can be upgraded are often a lot more expensive.	Pretty much every part within a computer can be upgraded in almost all PC computers. In addition because of the openness and competition between hardware vendors, parts are also often cheap and first available for the PC. Finally, if you plan on building your own computer the PC is the only way to go.
Drivers	Much of the hardware and drivers are developed by Apple. Because of this you are less likely to encounter driver related issues.	PC computers are often running hardware from dozens of different manufacturers and using dozens of different drivers. Therefore it's more likely you'll encounter driver issues then you would on a Mac.
Gaming	Although many (but not all) game developers are releasing games for both the Mac and PC most of them still release their games and updates to the PC first.	The PC is king when it comes to games and online gaming. All major games developed are released for the PC first. In addition PC users have the option of running higher performance video cards and getting the absolute best performance from their games.

Linux vs. Windows

Answer

Users who are considering making a change from Windows to Linux or Linux to Windows commonly want to know the advantages and disadvantages of each of the operating systems. Below is a chart to help illustrate the major advantages and disadvantages of each of these operating systems.

Topic	Linux	Windows
Price	The majority of Linux variants are available for free or at a much lower price than Microsoft Windows.	Microsoft Windows can run between $50.00 - $150.00 US dollars per each license copy.
Ease	Although the majority Linux variants have improved dramatically in ease of use, Windows is still much easier to use for new computer users.	Microsoft has made several advancements and changes that have made it a much easier to use operating system, and although arguably it may not be the easiest operating system, it is still Easier than Linux.
Reliability	The majority of Linux variants and versions are notoriously reliable and can often run for months and years without needing to be rebooted.	Although Microsoft Windows has made great improvements in reliability over the last few versions of Windows, it still cannot match the reliability of Linux.
Software	Linux has a large variety of available software programs, utilities, and games. However, Windows has a much larger selection of available software.	Because of the large amount of Microsoft Windows users, there is a much larger selection of available software programs, utilities, and games for Windows.
Software Cost	Many of the available software programs, utilities, and games available on Linux are freeware or open source. Even such complex programs such as Gimp, OpenOffice, StarOffice, and wine are available for free or at a low cost.	Although Windows does have software programs, utilities, and games for free, the majority of the programs will cost anywhere between $20.00 - $200.00+ US dollars per copy.
Hardware	Linux companies and hardware manufacturers have made great advancements in hardware support for Linux and today Linux will support most hardware devices. However, many companies still do not offer drivers or support for their hardware in Linux.	Because of the amount of Microsoft Windows users and the broader driver support, Windows has a much larger support for hardware devices and a good majority of hardware manufacturers will support their products in Microsoft Windows.
Security	Linux is and has always been a very secure operating system. Although it still can be attacked when compared to Windows, it much more secure.	Although Microsoft has made great improvements over the years with security on their operating system, their operating system continues to be the most vulnerable to viruses and other attacks.
Open Source	Many of the Linux variants and many Linux programs are open source and enable users to customize or modify the code however they wish to.	Microsoft Windows is not open source and the majority of Windows programs are not open source.
Support	Although it may be more difficult to find users familiar with all Linux variants, there are vast amounts of available online documentation and help, available books, and support available for Linux.	Microsoft Windows includes its own help section, has vast amount of available online documentation and help, as well as books on each of the versions of Windows.
