Does Linux support the ATI Radeon HD 3780?

Neither Linux nor the X Server (Xorg) have built-in drivers, due to the proprietary nature of the card. However, ATI / AMD does make proprietary drivers available for download (link available below).

What is an example of partitioning?

By far the most common use of partitioning on windows systems is to have just one big partition (drive C:) which accounts for 100% of the hard disk. All system files and user data are stored in this one single partition.

On Linux systems the hard disk is usually split up into 2 or 3 partitions, one for system files, one for applications, and a third for swap files.

When dual-booting, (installing two separate operating systems on the same system) it is common to install them onto separate partitions.

Most modern operating systems run a partition manager as part of their install routine. The installation process itself will walk you through partitioning the disks as needed. In the past it was necessary to configure all of this manually, but that is rarely the case these days.

Does Photoshop work in Linux?

While Adobe only supports Windows and Macintosh versions of Photoshop, you may be able to run Photoshop within Linux using Wine, a free application which attempts to allow programs written for Windows, to run on a Unix-like operating system.

What is Workspace switcher?

A workspace switcher allow one to have four (by default) different websites or files, etc. open on the Workspaces Utility and switch from one to the other at will.

Why Linux is safe operating system?

Largely for three reasons. But first I do have to point out that no system is impenetrable. Even Linux can be cracked.

Now, there are three primary reasons Linux is so secure:

1. It has a sane security model that can be extended and even overhauled as needed. Home users will be fine with the vanilla access control lists, but corporate users may like mandatory access control, such as Tomoyo or SELinux. The military actually mandates Linux has a working SELinux setup on their systems.

2. Linux users are, and I don't mean this as an insult to Windows or OS X users, the more competent computer users. The average Linux user knows how to keep their systems stable and secure better than the average Windows user, as many Linux distributions favor having users much more involved in the maintenance process. Many people think this is a shortcoming in Linux. I personally think it's better. One of the reasons, I think, Windows frequently fails is because it hides as much implementation as it can from the user. While it may make Windows "easy" it also means that Windows is impenetrable for the curious or the power user or for any do-it-yourself people who would like to fix and customize things.

3. Linux is open source. This is part of why there is a 1 and 2, but the third benefit comes from the fact that most Linux exploits are only 0-day exploits, as bugs are much easier for people to find. Someone encounters a bug, someone else finds the bug, someone else fixes the bug, and the kernel releases bug fixes very frequently. This means a particular exploit does not last long, making the lifetime of a virus very short.

Do .NET applications run on Linux?

Yes and no. Linux will not run Windows applications by itself, however, there are ample tools written for Linux that permit you to run Windows applications on Linux. The open-source WINE software will run a majority of Windows software on Linux. You can even configure Linux to automatically recognize Windows applications and use WINE to run them. Alternatively, there's a wide variety of virtual machine products that permit you to run the Windows operating system as an application under Linux, and, in turn, any Windows applications inside the Windows virtual environment. Finally, some "Windows applications" are written in .Net or Java and can be run directly under Linux using mono and java respectively (albeit, some .Net applications will not yet run under mono).

How was Linux developed?

Linux was developed by programmers around the world as a community project, started by Linus Torvalds in 1991. Using the Internet, Torvalds expressed an interest in creating a new operating system.

In an unprecedented move, Torvalds released what he had at that time on Internet under the GPL license. The GPL license allows you to share, and modify the program as you need, but also requires that all changes must be shared, so that everyone has the ability to use Linux equally. This effectively makes Linux "community property" to the entire world.

Mr. Torvalds was surprised when literally hundreds of bugfixes and improvements were offered by volunteers, almost immediately. Since then, Linux has grown through those volunteers to become one of the world's most widely used computer technologies for everything from the Internet webservers to cell phones.

Because anyone can contribute time, programming, or other help, people from hundreds of countries around the world contribute programming improvements, translations, documentation, and advice. Some are paid by companies such as IBM and RedHat, but most do so for free and the sense of community spirit.

What is the performance of a Linux operation system?

Depending on what's installed, Linux generally requires fewer resources than Windows and thus, performs faster.

What is the directory in a Linux file system where remote NFS files are accessed as though the files were local called?

There is no specific directory on which you have to access NFS shares. You can mount a specific NFS share as root, or a subdirectory therein, such as /home.

How do you bring a job to the foreground in Linux?

fg [job id]

where [job id] is the job number associated with the process. You can find the job id by issuing the jobs command.

Which Linux command can be used to determine the available space on local hard-disk partitions?

df

df - report file system disk space usage

du

du - estimate file space usage

What is a Linux certification?

Linux certification is a programming certification. It shows you have a lot of knowledge in programming.

What is clustering in Linux?

"Clustering" is the method of linking several computers (or servers, usually) together to act as one. This way, at least for servers, it balances high-traffic loads, and prevents overloading.

Clustering is also leveraged for combined processing power. For example, you could use a cluster of machines to try and crack an encryption, therefore speeding up the process with extra processing power.

What is the installation program called for Linux?

There is no "the" installation program for Linux. Each distribution has its own (more or less), and it's generally referred to as "the installer" unless they've given it a more specific name.

What does the ulimit parameter do in Linux?

The ulimit parameter in Linux is set so the user can only use a set number of processes which is authorised by the server. The ulimit parameter can be changed accordingly if needed.

Why is Linux?

A simple question, but one that could result in a long and convoluted answer. Basically, Linux is the kernel from which many distributions burst forth, like a rocket exploding in a mass of sparkling stars on Bonfire Night. Linux Torvalds initially created Linux, then with the help of like-minded computer enthusiasts, a community rocket was sent up to explode in the computer world.

What are common commercial versions of Linux?

Red Hat Enterprise Linux - produced by Red Hat

SUSE Linux Enterprise Server - produced by Novell

Ubuntu (available free of charge, but has paid support available) - produced by Canonical.

Why to use samba file server?

A free software package, Samba enables network access to Linux and UNIX® file and print services. Samba's core functionality derives from its implementation of the Server Message Block (SMB) protocol. SMB client- and server-side support comes bundled with Windows 95 and newer versions of Microsoft Windows. This large installed base has helped Samba grow in popularity...

From the perspective that samba is everywhere, then yes it is good. If you are asking if it is a good protocol, then the answer is that it isn't really all that great. It has large problems on links with high latency. It has far too many redundant commands.

Where you can find com port terminal program for Linux?

Minicom (for the command line) and PuTTy (graphical) can both connect as a client to other computers through a serial port (/dev/ttySx). Minicom can also provide server functionality.
