what is the functions of initrd image, which is present in memory during boot process

The initrd image contains the necessary executables and system files to support the second-stage boot of a Linux system.

Depending on which version of Linux you're running, the method for creating the initial RAM disk can vary. Prior to Fedora Core 3, the initrd is constructed using the loop device. The loop device is a device driver that allows you to mount a file as a block device and then interpret the file system it represents. The loop device may not be present in your kernel, but you can enable it through the kernel's configuration tool (make menuconfig) by selecting Device Drivers > Block Devices > Loopback Device Support. You can inspect the loop device as follows (your initrd file name will vary):

The initrd or initial ramdisk image is a temporary file system that is used by the kernel during boot.

In other words this is a set of instructions or information that is loaded first and which assists in loading rest of the information to boot Linux.
