Decode the Basics of Linux with Device Driver Training

You would have come across Windows device driver, which besides providing an interface to the hardware makes assumptions on the probable uses of that particular hardware. A Linux device driver on the other hand is responsible for the interface only and has nothing to do with how it will affect usability aspect of the hardware. Moreover, such drivers don't play any sort of active part in bestowing graphical interfaces to the hardware. The community of Linux developers actively contributes to create and maintain the Linux kernel source tree, which further serves as the basis of most of Linux supported hardware drivers. Device Driver Training allows students to learn the essential tenets of software programming and hardware's practical use as well.

A driver is responsible only for providing access to particular hardware or a set of hardware. For doing so, Linux does not rely on any type/s of Application Binary Interface or ABI, a regular feature of Microsoft drivers, to make particular hardware accessible. Application Binary Interface for Linux device drivers is somewhat impractical and useless and you will not find any such interface in Linux. The Linux Kernel and the hardware is not direct accessible from the user space. The kernel has a set of system calls and all the communication from the user space and the kernel space happens through these system calls only.

These system calls serves as a reliable user space interface for myriad applications, which further helps in creation of dedicated modules for device drivers' creation. While creating these drivers, the modules maintain their separate identity; however, they conform to standardized system calls for serving special functions. Hence, the first thing you need to understand is that device drivers for Linux owe their existence and creation to the kernel tree. Thus, you can insert or remove any or each module from kernel at runtime; however, such actions are subject to kernel configuration which was configured while compiling the kernel.

The users further need to understand the capability and usability aspects. Device Drivers work rather discreetly on the usability front; the drivers do not actually tell you about their probable uses. Hardware devices may further be categorized into three main classes, namely network interfaces, block devices and character devices. While network devices make it possible to exchange data with other hosts through packet transmission, a block device is always accessible in the form of blocks and as such, is quite capable of hosting a file system. A character device, on the other hand, is akin to a file, which further includes serial ports, text console and keyboard. Basically, a character device is a steady stream of bytes or characters. Linux device driver training allows you get a hang of Linux basics.

Further, an open source GNU General Public License (GPL) licenses the Linux kernel, which further facilitates its free availability. After downloading a particular kernel, people may alter, modify or redistribute it further. However, same assumption cannot be applied to Linux device drivers because of their modular nature. Since drivers are modular, they aren't actually parts of the kernel. But for interacting with the hardware , the driver has to be a part of the kernel , usual process is by inserting it as a module in runtime. The driver needs to have a GPL license if it has to be inserted successfully in the kernel . Some modules or drivers will also have another kind of license "BSD" and some will also have a dual license "GPL/BSD".

20 Things You Didn't Know About Windows XP

You've read the reviews and digested the key feature enhancements and operational changes. Now it's time to delve a bit deeper and uncover some of Windows XP's secrets.

It boasts how long it can stay up. Whereas previous versions of Windows were coy about how long they went between boots, XP is positively proud of its stamina. Go to the Command Prompt in the Accessories menu from the All Programs start button option, and then type 'systeminfo'. The computer will produce a lot of useful info, including the uptime. If you want to keep these, type This creates a file called you can look at later with Notepad. Professional Edition onlYou can delete files immediately, without having them move to the Recycle Bin first. Go to the Start menu, select Run... and type 'gpedit.msc'; then select User Configuration, Administrative Templates, Windows Components, Windows Explorer and find the Do not move deleted files to the Recycle Bin setting. Set it. Poking around in gpedit will reveal a great many interface and system options, but take care -- some may stop your computer behaving as you wish. Professional Edition only.You can lock your XP workstation with two clicks of the mouse. Create a new shortcut on your desktop using a right mouse click, and enter 'rundll32.exe user32.dll,LockWorkStation' in the location field. Give the shortcut a name you like. That's it -- just double click on it and your computer will be locked. And if that's not easy enough, Windows key + L will do the same.XP hides some system software you might want to remove, such as Windows Messenger, but you can tickle it and make it disgorge everything. Using Notepad or Edit, edit the text file /windows/inf/sysoc.inf, search for the word 'hide' and remove it. You can then go to the Add or Remove Programs in the Control Panel, select Add/Remove Windows Components and there will be your prey, exposed and vulnerable.For those skilled in the art of DOS batch files, XP has a number of interesting new commands. These include 'eventcreate' and 'eventtriggers' for creating and watching system events, 'typeperf' for monitoring performance of various subsystems, and 'schtasks' for handling scheduled tasks. As usual, typing the command name followed by ? will give a list of options -- they're all far too baroque to go into here.XP has IP version 6 support -- the next generation of IP. Unfortunately this is more than your ISP has, so you can only experiment with this on your LAN. Type 'ipv6 install' into Run... it's OK, it won't ruin your existing network setup and then 'ipv6 ?' at the command line to find out more. If you don't know what IPv6 is, don't worry and don't bother.You can at last get rid of tasks on the computer from the command line by using 'taskkill /pid' and the task number, or just 'tskill' and the process number. Find that out by typing 'tasklist', which will also tell you a lot about what's going on in your system.XP will treat Zip files like folders, which is nice if you've got a fast machine. On slower machines, you can make XP leave zip files well alone by typing 'regsvr32 /u zipfldr.dll' at the command line. If you change your mind later, you can put things back as they were by typing 'regsvr32 zipfldr.dll'.XP has ClearType -- Microsoft's anti-aliasing font display technology -- but doesn't have it enabled by default. It's well worth trying, especially if you were there for DOS and all those years of staring at a screen have given you the eyes of an astigmatic bat. To enable ClearType, right click on the desktop, select Properties, Appearance, Effects, select ClearType from the second drop-down menu and enable the selection. Expect best results on laptop displays. If you want to use ClearType on the Welcome login screen as well, set the registry entry HKEY_USERS/.DEFAULT/Control Panel/Desktop/FontSmoothingType to 2.You can use Remote Assistance to help a friend who's using network address translation (NAT) on a home network, but not automatically. Get your pal to email you a Remote Assistance invitation and edit the file. Under the RCTICKET attribute will be a NAT IP address, like 192.168.1.10.

Right click the icon, select Run As... and enter the user name and password you want to use. This only applies for that run. The trick is particularly useful if you need to have administrative permissions to install a program, which many require. Note that you can have some fun by running programs multiple times on the same system as different users, but this can have unforeseen effects.Windows XP can be very insistent about you checking for auto updates, registering a Passport, using Windows Messenger and so on. After a while, the nagging goes away, but if you feel you might slip the bonds of sanity before that point, run Regedit, go to HKEY_CURRENT_USER/Software/Microsoft/Windows/Current Version/Explorer/Advanced and create a DWORD value called EnableBalloonTips with a value of 0.You can start up without needing to enter a user name or password. Select Run... from the start menu and type 'control userpasswords2', which will open the user accounts application. On the Users tab, clear the box for Users Must Enter A User Name And Password To Use This Computer, and click on OK. An Automatically Log On dialog box will appear; enter the user name and password for the account you want to use.Internet Explorer 6 will automatically delete temporary files, but only if you tell it to.

Right click on My Network Places on the desktop, then select Properties. Right click on the description for your LAN or dial-up connection, select Properties, then check the Show icon in notification area when connected box. You'll now see a tiny network icon on the right of your task bar that glimmers nicely during network traffic.The Start Menu can be leisurely when it decides to appear, but you can speed things along by changing the registry entry HKEY_CURRENT_USER/Control Panel/Desktop/MenuShowDelay from the default 400 to something a little snappier.

Enhance Windows with Nine Free Tools

Windows is feature packed Operating system. However there are free substitute which are efficient and highly powerful and take minutes to fix. Those same features can be replaced by these free applications.

Search

The search utility in Windows 8 is integrated and fast with new start screen. However the start screen search is not ideal. It cannot find files which are not executable. Do you want to search through every file on your system? Then you would have to use File Explorer search. Or, you can use Everything.

You can use 'Everything' program. Just type and it would find what you have been looking for thereby narrowing down results letter by letter. This is a search utility which allows you to explore every single file on your system instantly. Pin it to the toolbar in order to access quickly.

Transferring of files

Though transferring of files is an easy task but irritating too. However it has become netter in the latest version s of Windows. However it does take time and any mistake can spoil your day. Make use of Teracopy that makes large batches of shuffling files simple in a jiffy.

It is a free functionality which speeds up file transferring and protects from any failed transfers. In case there is any error it would skip that file and not send it. If you want you can pasue and tehn retsrat the transfer. It combines directly with Windows Explorer.

Screenshots

You can take a screenshot by pressing Win-PrtScn in Windows 8, but you should take a bunch as well as get a dedicated screenshot app. Greenshot is a utility which gives you coarse as well as customized controls for quick screenshot taking.

Htkeys can be binded to all sorts of screenshot commands and specify what would happen with those screenshots. You can open a 'Save As dialogue', open the screenshots in a trivial image editor or even save them to the hard drive.

Process manager

Windows process manager pops up when you hit Ctrl-Esc-Shift or even open the "Processes" tab in the Windows task manager. It shows as to which processes and programs are running and the resources they use.

You can use Process Explorer offered by Microsoft which is a task manager for power users. It digs even deeper into the dynamic processes.

They are grouped into a suitable tree structure thereby allowing you to see everything in a single place. They are also color coded thereby helping you to differentiate easily. You can connect to the Internet helping you to detect the mysterious ones or those that slow down the computer.

Notepad

Notepad is a plain-text editor. It is highly simple and that is its merit too. If you want more you can use Notepad++'s numbered lines. This is also a plain-text editor which retains the simplicity as well as uses several other features. It has a customized user interface which helps you to edit several files at once and includes spell-check.

Decompression

If you want something more than an exotic standard, compressed .zip file then you can use RAR. It is the most common archive format. You need a good program like 7Zip. This is a free functionality which can open.zip, .rar, and any other archive file format. You can create .zip and .7z files that offers the best compression of archive type. Compress several files and save space with this.

Media Player

Media playback can be a dilemma. You are never sure as to when you need to play a file. You can predict though as to when the job is not done. VLC can play any media file which is a compact media-player application. DVDs can be played easily, this function was removed from Windows Media Player in the edition of Windows 8.

Paint

MS Paint is been there for long. In case you require any image-editing power just download a replacement called Paint.NET. This is powerful and simple which is a rare combination in free software. It has features of modern image editor, like filters, layers and a history pane wrapped in a good user interface.

So this is the point on which, you need to take a pause and think considerably.

Software licenses

The next important thing which you need to consider is the license of the software. Software in the market is available with different usage licenses such as single-user, multi-user, concurrent and site. The software with single user license can be used on one PC. On the contrary, multi-user software can be installed on several machines. It is more suitable for professional units where you require software for several PCs.

Look at the types of software

The last but not the least tip for choosing the right OS for your PC is to look into the types of software. This is another type of software licensing that determines the restrictions and access policies or rights to use the software. Types of software can be classified into following categories.

Public Domain

Public domain software are those that are free to install and use without any copyright restriction.

Shareware

Shareware are the software that contain ad material and poses usage restriction.

Custom-made Software

Such software are designed in a specific environment to precisely meet the requirement of a designated client.

Open Source software

It is a kind of freeware which is freely available for variety of users. Users can also access the source codes of such software without any restriction.

Over and above the above mentioned tips, you are also recommended to some online research to know more about the advantages and disadvantages of various operating systems. After considering all these factors and suitability to your PC, you should choose your OS as it is the software that will determine the performance of your PC.

Decode the Basics of Linux with Device Driver Training

You would have come across Windows device driver, which besides providing an interface to the hardware makes assumptions on the probable uses of that particular hardware. A Linux device driver on the other hand is responsible for the interface only and has nothing to do with how it will affect usability aspect of the hardware. Moreover, such drivers don't play any sort of active part in bestowing graphical interfaces to the hardware. The community of Linux developers actively contributes to create and maintain the Linux kernel source tree, which further serves as the basis of most of Linux supported hardware drivers. Device Driver Training allows students to learn the essential tenets of software programming and hardware's practical use as well.

A driver is responsible only for providing access to particular hardware or a set of hardware. For doing so, Linux does not rely on any type/s of Application Binary Interface or ABI, a regular feature of Microsoft drivers, to make particular hardware accessible. Application Binary Interface for Linux device drivers is somewhat impractical and useless and you will not find any such interface in Linux. The Linux Kernel and the hardware is not direct accessible from the user space. The kernel has a set of system calls and all the communication from the user space and the kernel space happens through these system calls only.

These system calls serves as a reliable user space interface for myriad applications, which further helps in creation of dedicated modules for device drivers' creation. While creating these drivers, the modules maintain their separate identity; however, they conform to standardized system calls for serving special functions. Hence, the first thing you need to understand is that device drivers for Linux owe their existence and creation to the kernel tree. Thus, you can insert or remove any or each module from kernel at runtime; however, such actions are subject to kernel configuration which was configured while compiling the kernel.

The users further need to understand the capability and usability aspects. Device Drivers work rather discreetly on the usability front; the drivers do not actually tell you about their probable uses. Hardware devices may further be categorized into three main classes, namely network interfaces, block devices and character devices. While network devices make it possible to exchange data with other hosts through packet transmission, a block device is always accessible in the form of blocks and as such, is quite capable of hosting a file system. A character device, on the other hand, is akin to a file, which further includes serial ports, text console and keyboard. Basically, a character device is a steady stream of bytes or characters. Linux device driver training allows you get a hang of Linux basics.

Further, an open source GNU General Public License (GPL) licenses the Linux kernel, which further facilitates its free availability. After downloading a particular kernel, people may alter, modify or redistribute it further. However, same assumption cannot be applied to Linux device drivers because of their modular nature. Since drivers are modular, they aren't actually parts of the kernel. But for interacting with the hardware , the driver has to be a part of the kernel , usual process is by inserting it as a module in runtime. The driver needs to have a GPL license if it has to be inserted successfully in the kernel . Some modules or drivers will also have another kind of license "BSD" and some will also have a dual license "GPL/BSD".

Android VS iOS - Which One is Better?

Android VS IOS- which one is better?

Android and IOS are very common words for technology enthusiasts and Smartphone users. It is a Linux-based designed for smartphones and tablet computers developed by Google operating system. On the other hand, IOS is developed and marketed by Apple Inc. mobile operating system.

Take a closer look at Android ios:

A. Proprietary Vs Open Source IOS

Apple governs its rights on its IOS. This proved to be a boon for Android. The device is totally free and also an open source, which means that anyone can have a look and modify its code. This has led to a huge percentage of the population of application programmers opt or switch to this device

Thus, in the war of Apple Vs Android - Android wins because of some advantages

2. Applications

Although Google says its Android Market is huge and popular, but the reality is that currently it is far from Apple's App Store. Also, I personally like to emphasize that the most popular Android applications are already popular on IOS and then are transported to another platform. I do not think there is any application that has been transported to Android to Apple because of its popularity.

3. Hardware

Personally, I 'm a fan of Apple hardware. But they also kept their prices really high to a normal user like me. So here's Android, with companies such as LG and Samsung literally the provision of free equipment to anyone interested.

4. Developers

This is another crucial factor. Application developers of Apple are having a hard time to download applications from the App Store because they have to go through all the controls. On the other hand, Google said that it's developers are free to publish their applications on it's Market. And more and more applications are on the way for Android users.

Considering all the above factors, I can safely say tha tit has a very bright future in the war of Google device Vs Apple IOS, Android will be the winner. It is so far the best device that has been used by the users.
