CHIPSETS OF COMPUTERS.

A CHIPSET IS A COLLECTION OF CHIP OR CIRCUITS THAT PERFORM INTERFACE AND PERIPHERAL FUNCTION FOR THE PROCESSOR.THIS COLLECTION OF CHIPS IS USUALLY THE CIRCUITS THAT PROVIDES INTERFACES FOR MEMORY EXPANSION CARDS AND ONBOARD PERIPHERALS AND GENERALLY DICTATES HOW A MOTHERBOARD WILL COMMUNICATE WITH THE INSTALLED PERIPHERALS. CHIPSET ARE USUALLY GIVEN A NAME AND MODEL NUMBER BY THE ORIGINAL MANUFACTURER AND MODEL ALSO TELL YOU THAT YOUR PARTICULAR CHIPSET HAVE A CERTAIN SET OF FEATURES EG TYPE OF RAM SUPPORTED TYPE AND BRAND OF ONBOARD AND SO ON.
CHIPSETS CAN BE MADE UP ONE OR MORE INTEGRATED CIRCUIT CHIPS.INTEL BASED MOTHER BOARDS TYPICALLY USE TWO CHIPS.THE FUNCTION OF CHIPSETS CAN BE DIVIDED INTO TWO MAJOR FUNCTIONAL GROUPS CALLED NORTH BRIDGE AND SOUTH BRIDGE.
NOW I AM GOING TO SHOW YOU SOME OF THE BASIC CHIPSET IN COMPUTERS AND WIDELY USED CHIPSETS USED IN MODERN COMPUTERS .THEIR NAMES AS 1) NORTH BRIDGE 2) SOUTH BRIDGE
SO LET US BEGIN IN OUR LITTLE JOURNEY.

CHIPSETS CAN BE MADE UP ONE OR MORE INTEGRATED CIRCUIT CHIPS.  INTEL BASED MOTHER BOARDS TYPICALLY USE TWO CHIPS.  THE FUNCTION OF CHIPSETS CAN BE DIVIDED INTO TWO MAJOR FUNCTIONAL GROUPS CALLED NORTH BRIDGE AND SOUTH BRIDGE.

NOW I AM GOING TO SHOW YOU SOME OF THE BASIC CHIPSET IN COMPUTERS AND WIDELY USED CHIPSETS USED IN MODERN COMPUTERS .  THEIR NAMES AS 1) NORTH BRIDGE 2) SOUTH BRIDGE

SO LET US BEGIN IN OUR LITTLE JOURNEY.

NORTH BRIDGE

THE NORTH BRIDGE SUBSETS OF MOTHERBOARD CHIPSET, IS THE SET OF CIRCUITS OR CHIPS THAT PERFORM ONE VERY IMPORTANT FUNCTION: MANAGEMENT OF HIGH SPEED PERIPHERAL COMMUNICATIONS.

  THE NORTH BRIDGE IS RESPONSIBLE PRIMARILY FOR COMMUNICATIONS WITH INTEGRATED VIDEO USING AGP AND PCIE AND PROCESSOR TO MEMORY COMMUNICATIONS.  THEREFORE IT CAN BE SAID THAT MUCH OF THE TRRUE PERFORMANCE OF A PC RELIES ON THE SPECIFICATION OF THE NORTH BRIDGE COMPONENT AND ITS COMMUNICATION CAPABILITY WITH THE PERIPHERALS IT CONTROLS.

THE COMMUNICATIONS BETWEEN THE CPU AND MEMORY OCCUR OVER THE FRONT SIDE BUS(FSB). WHICH IS JUST A SET OF SIGNAL PATHWAYS CONNECTING THE CPU AND THE SYSTEM MEMORY .  THE CLOCK SIGNAL THAT DRIVES HE FSB IS USED TO DRIVE COMMUNICATION BY CERTAIN OTHER DEVICES, SUCH AS AGP AND PCIE SLOTS.

THE NORTH BRIDGE IS DIRECTLY CONNECTED TO THE SOUTH BRIDGE.  IT CONTROLS THE SOUTH BRIDGE AND HELPS TO MANAGE THE COMMUNICATION BETWEEN THE SWOUTH BRIDGE AND THE REST OF THE COMPUTER.

SOUTH BRIDGE

THE SOUTH BRIDGE IS SUBSET OF THE CHIPSET IS RESPONISIBLE FOR PROVIDING SUPPORT TO THE ONBOARDS SLOWER PERIPHERALS SUCH AS PS2, PARALLEL PORTS, SERIAL PORTS, PATA, SATA ETC. MANAGING THE COMMUNICATION WITH THE REST OF THE COPUTER AND THE RESOURCS GIVEN TO THEM.

THESE COMPONENTS DO NOT NEED KEEP UP WITH THE EXTERNAL CLOCK OF THE CPU AND DO NOT REPRESENTS A BOTTLENECK IN THE OVER ALL PERFORMANCE .  THE SOUTH BRIDGE IS ALSO RESPONSIBLE FOR MANAGING COMMUNICATIONS WITH THE SLOWER EXPANSION BUSES LIKE PCI SLOT ETC.

LOGIC OF COMPUTERS

LOGIC OF COMPUTER IN PAPER AS WELL AS PRACTICAL USE



We always use logic in every day matters, so do the machines.But we were taught by experiences we count and the people we trust and these things matters most because it will help in dark times.But to make the machine understand the logic is very hefty work. But this is certainly not impossible.In order to understand logic we use integrated circuits.But to do this we need to design the integrated circuits on paper.This requires certain rules of algebra.This I am going talk about the rule of an algebra called the duality principal.
It states that every algebraic expression deducible from the postulates of Boolean algebra remains valid if the operators and identity elements are interchanged.In a two value Boolean algebra, the identity elements and the elements of the set B are same 1 and 0.The duality principal has many applications.If the dual of an algebraic expression is desired, we simply interchange OR and AND operators and replace…

INTERNET A GLIMPSE

We live in a world where every field requires use of computers.But computers need data to process the output.This data can be gathered with the help of internet.The internet uses World Wide Web to gather data.So the user must know the basics of the internet.So I am going to acknowledge the basic parts where and how the computer uses internet. I am going to discuss about OSI layers.
Osi means open system interconnectand was invented by ISO (INTERNATIONAL SYSTEM OF ORGANIZATION) which is an institution who manages giving standardization of the products to be manufactured.It was invented by iso in 1984.The use of iso in networking terms is to provide networking standardization of frame workfor implementing network protocols to be used in seven layers.
The seven layers breaks down the process of communication into smaller and easier to handle independent categories.Before osi different networking vendors couldn’t communicate with each other.After iso now different vendors have the abili…

MATHEMATICS AND COMPUTER SCIENCE RELATIONSHIP

MATHEMATICS AND COMPUTER SCIENCE RELATIONSHIP.


In today’s world mathematics is a must learned subject .In all the inventions and discovery , the main reason for their success of the practical’s are due to mathematics.So in order to make a career in today’s world require mathematics.
But this Is blog of computers science and information technology, then why should we read mathematics so it requires mathematics to understand the reason behind such technology.So I am going to write something about mathematics for its uses and technology in the computer world. One of the main aims of logic is to provide rules by which one can determine whether any particular argument or reasoning is valid (correct) Logic is concerned with all kinds of reasoning whether they be legal arguments or mathematical proofs or conclusions in a scientific theory based upon a set of hypothesis.Because of the diversity of their application these rules are called rules of inference, must be stated in general terms and …
