Each program that is waiting for Input/Output is put into a blocked state inside the computer. The programs only enter the Ready/Running state when they are available to perform I/O operations. Because of DMA (Direct Memory Access) and because of the fact that most processes will be blocked, the effect of having a reasonable number of I/O programs will be minimal to the performance of your machine. If you have an extravagant number of I/O programs, your computer will see significantly slower performance.
to find out the memory of each processes running on our unix/ Linux box type "PS -aux | more" would list u all the processes running with their respective processor id's (pid) and the memory used by the respective programs ... if u are running out of memory what we can do is note down the pid which is taking lot of memory and if u feel the process is not so important for u then use the command "killall"to quit or stop that particular process I am using red-hat Linux, here u can use a top command to c the amount of memory utilized by each running processes. You can use "top" or the native "prstat" in Solaris. In order to see how much memory is used by a process, not including that shared with other processes ( through shared libraries ), you can execute "pmap -x $pid" giving your processes PID.

True multi-tasking is achieved through parallel processors. If you only have one processor, only one task can execute at a time. You can still multi-task by rapidly switching between all the running processes, but you cannot have two processes running simultaneously. With two or more processors running in parallel, you can.
Yes. There are 5 different ones. Each block has a different spot blocked. One doesn't have any blocked.
Friends normally look after friends. If you have the sort of fifreinds who would block you on XBox live then you need to find out why.If you have blocked a friend in X Box Liver then they need to find out why. You have your frinds and I have have mine.
Multitasking is the simultaneous running of several processes by a single machine. PCs are an example of multi-tasking machines. They are capable of running several programs at the same time as well as numerous background tasks such as network control, file management, printer control and many more. The processes are normally under the control of housekeeping software that allocates computer resources to each of the tasks as they are needed.
Twitter was blocked in Egypt while the Egyptian Riots/Revolution was going as they realised that this is how they were communicating. so they blocked it so that they wouldn't be able to contact each other via Twitter. they also blocked other Internet resources.

Blocked Account is called Sperrkonto in German. For obtaining a students Visa, German embassy requires opening of blocked account with adequate funds to support yourself during the study. You can only withdraw a certain amount each month, the rest is blocked for future use. You can open a blocked account from your home country through Deutsche Bank.
The 'ps' command will give you all the currently running processes. Each Unix system may have slightly different options to list them. The most common would be: ps -ed or ps -ef or ps -el depending on how much information you want to see.
There is a unique ECG pattern for blocks in each of the three bundles.
