Like device driver， I don't know whether there are some other drivers ?
Taken from Windows Internals 4th (XP-based) Edition:
Hardware device drivers - Drivers using the HAL
File System Drivers - File IO for devices
File System Filter Drivers - Intercept IO and do processing on it (like AV and such)
Network Redirectors and Servers - Transmit IO on the network
Protocol Drivers - Implement network protocol like TCP/IP
Kernel Streaming Filter Drivers - Signal processing on data streams like video/audio
What comes to mind straight away is virtual device drivers - usually emulating some kind of device, but not being a device themselves.
Probably worth a mention is class drivers that can talk to an entire class of devices (e.g. USB).
And the Wikipedia article on device drivers may be a good starting point.

I want to write Linux device driver for network based device. This network device is just Input output control only and also this device connects through Ethernet port via ethernet cable. How can i write driver? How to transfer data between device and kernel?
If the device just connects to the Linux machine through Ethernet, then you don't need to write a kernel driver at all - a userspace daemon can have full access to Ethernet through the AF_PACKET socket address family. See the packet(7) man page for details.
You can choose for a TCP or UDP connection communication.
for TCP you must opt for a stream based transfer
But UDP is not a reliable communication rather it is faster as compared to TCP.
I would suggest to go with Beginning Linux Programming which has a theoretical as well as a practical reflection.
Cheers !!

I want to write a program for transferring files and documents between a network computers. Many files may have been transferring at moment. every computer can receive and send files, it means system have to be ready to send files and listening to receive files.
I can configure program on each system as i want (for example give a list of connected computers' ip to program to choose target system for transfer file into)
Do i have to make Server-Client type applications or i can have JUST one program running on computers? I know question is vast but helping me to choose the best way will be appreciated.

I want to write this program by Delphi 2010 and network computers os is Windows 7.
You can do it peer-to-peer. The very same program can both listen for requests to transfer or receive files from other computers and issue its own requests to transfer or receive files to other computers.

I want to transfer data directly between iOS and Mac(short distance) via bluetooth or Wi-fi.
I read some question and if we use bluetooth, we must add Bluetooth LE adapter and I don't want it.
If we use Wi-fi, that will effect on current Internet network.
What's the best and fastest way? I just want to send small data directly.
Please help!
Look into Apple's Bonjour technology: Bonjour Tutorial
It might take a lot of work off the table, from discovering what other computers / devices are nearby to getting their IP Addy.
You can use NSStream or this third party Library and Tcp protocol. You can use Bonjour to help in network devices discovery. Both of the links above have samples applications. Note: both devices needed to be on the same lcal network.

What options do we have to enable a user of an app to share a file with another user on another device ?
My application is a task management app, I want to enable my users to share lists, notes, etc.
I haven't found a way to do this with iCloud.
Depending on how you want to implement the work-flow, there are a number of ways to accomplish this.
Spotify allows users to sync files between computers and mobile devices, if both are on the same local network. You could use Bonjour to discover if there are any valid endpoints on the local network, and then sync directly over a TCP/IP socket.
If you're looking for cloud sync, Parse provides a cloud-app-api service that lets you easily store objects, including files and binary data on the cloud. You'll have to write your own user management layer, but they provide API's for storing and retrieving data.
From the comments, there are other companies that provide similar services to parse: Buddy, Stackmob, Kinvey, and applicasa to name a few. The idea is to leverage an API-as-a-Service provider for all backend needs.

I want to learn device driver development so how to start ? Any media for beginner or something ?
The canonical reference is Linux Device Drivers 3rd Edition - although it's a few years old now, it's close enough to current kernels.
Quite a lot of stuff is not covered in here - particularly anything that's device or bus specific, or the way the kernel has been developing to support ARM SoC devices over the last few years.
I would suggest to go start learing Linux device driver under PC environment so as you can co-relate most of things you are familier with ,One approach is to go get linux source code and try to understand how kernel is being called and how single user space process is initiated from kernel space .You can also follow this below given page would be helpful for you.
