Time sharing means that many users share a single computer. This was in the days of big mainframes and dumb terminals. It is an example of multitasking (many processes running on one processor). Time slice is one way that processors can multitask. This was the origin of client/server programming, many clients share the server.
Distributed computing is when a process running on one computer uses software modules running on many other computers. The Seti-At-Home screensaver is an example of distributed computing. The screensaver running on your computer calculates a small set of all the data collected by Seti when you processor is idle. The main computer collects all the analysed data from thousands of running screensavers.
The following is about preemptive/non-preemptive multitasking. It is concerned with only one computer. In a time slicing computer, there is an algorithm that decides how much time on the processor each of the processors need. It can very this dynamically. If a certain process doesn't voluntarily give up it's control of the processor, the central time-slicing process can force it off the processor. Most operating systems use time-slicing. Unix, Linux, OS X, Windows XP, etc. all use it.
In a distributed/cooperative computer, each process has to willingly give up its control of the processor when it's done. If a process doesn't give up control, then the whole computer crashes. This is a lot less stable. Any Mac OS prior to OS X uses distributed processing.

Difference between batch sharing and time sharing?
The main difference between batch sharing and time sharing is that in batch sharing system tasks are processed in order in which they arrive. Whereas, in the later the system switches between tasks.
Difference between giving and sharing?
sharing is giving some but not all away.
What is the difference between file sharing and downloading files?
In file sharing you transfer files from another computer connected to internet. While in case of downloading you receive files from dedicated servers.
The difference between block grants and revenue sharing?
A block grant is a specific amount of money received that is then designated for specific projects or areas. Revenue sharing is the amount a business profits and how that monies are distributed to the shareholders, partners, employees etc.

What is the difference between ionic bond and polar covalent bond?
The ionic bond is formed by electrostatic attraction between two atoms.In the polar covalent bond the electrons sharing is unequally distributed between the two atoms, but the bond remain covalent.
What is the difference between electron transfer and electron sharing?
ionic bonding
A covalent bond involves sharing of?
A covalent bond is the sharing of electrons between atoms when there is no or slight difference in electronegativity.
What is the difference between router and firewall?
A router is a device in a computer that allows sharing of internet connection between more than one computer. However; a Firewall is used as a security to allow or disallow different type of traffic through your connection.
What is the difference between P2P file sharing and traditional file sharing?
In peer-to-peer sharing you are using a software program and not you browser. And there is a computer to computer charing system instead of servers. All you need to do is type in what you want and probally it will come up as found. And you can download it. And in traditionaln file sharing you can either go trough a server or two computers near by on the same internet way.
What is the difference between a ionic bond covalent bond and a polar covalent bond?
Ionic bond: this bond is based on electrostatic attraction of ions.Covalent bond: electrons are shared between atoms.Covalent polar bond: electrons are shared between atoms but the sharing is not equally distributed.
What is the difference between distributed systems and systems connected in a network?
"systems connected on a network" only says that the computers CAN exchange information. a "distributed system" implies that the computers are sharing information to accomplish a purpose, for example, to provide for a program or application where parts of it run on different computers. An example of a distributed system is one where the database runs on one computer, the accounting software that uses the database runs on another computer, and the user who wants to enter data into the system runs on a third computer. Computers that are merely on the same network together may not have all the software pieces in place to achieve this kind of cooperation.
