ARITHMETIC CALCULATION IN COMPUTERS

ARITHMETIC OPERATION AND CONVERSION DONE BY COMPUTER
As we have seen in previous post that arithmetic computation is an important thing in calculation, if a person doesn’t know arithmetic computations,he will be doomed to be in trouble during calculations that happensin everyday life.So it is necessary to learn arithmetic computation.So in this post I am going to take one step further.I am going to write about octal and hexadecimal numbers.
Now let us discuss some arithmetic conversion.Let us see what is octal and hexadecimal numbers used by digital computer.
The conversion from and to binary, octal and hexadecimal plays an important part in digital computers.Since 23 = 8 and 24 = 16 each octal digit corresponds to three binary digits and each four binary digit corresponds to one hexadecimal digit.
The conversion of from binary to octal is easily accomplished by partitioning the binary into group of three digit each, starting from binary point and preceding to the left or to the right…

MONITORS: A COMPUTER PART

Folks today i am going to say something about an output device called monitor.As maximum people know about monitors so i am going to write few things about monitor much of the information you know but i am going to say some few words hence please be with me.
Monitor is a primary output device.It displays all current process application and data i.e. Running inside a computer system.A standard monitor uses an analog vga interface, which plugs into a tp15 vga connector to a mother board.There are two types of monitor technology available to the market.
CATHODE RAY TUBE (CRT MONITOR)
This monitor is fading in popularity but still in widespread use with older computer systems.It is analog standard monitor a crt uses a picture tube that was used in older tube based tv sets.
The narrow end of the picture tube contains an electron gun it emits 3 electron beams one each for red, green and blue light.The front end of the picture tube is coated with phosphorous.When the elecron hit the phosphorou…

SUMMARY OF MEMORY

RAM PROPERTIES Friends in the last post i tried to explain the different types of ram as well as given the details of its similarities now i am going to show you how the properties of ram can be judged .
SO LET US BEGIN.
SINGLE SIDED VS DOUBLE SIDED DIMMS or DUAL INLINE MEMORY MODULE whatever you call are often referred to as single chip or double sided to describe whether the chips are located on one or both of the modules printed circuit board .
However these terms may cause confusion or distract you from the topic, as the physical layout of the chips does not necessarily relate to how they are logically organized or accessed in whatever terms you are told.
ERROR CORECTING CODE MEMORY (ECC MEMORY) An ERROR CORRECTING CODE (or ECC) whatever general public says could be akind of computer data storage which will detect and proper the more common types of internal data corruption in simple words with firmness and boldness.

PROCESSOR AND HYPER THREADING A SHORT SUMMARY

PROCESSOR AND HYPERTHREADING
Friends in the last post i tried to say something about computer science and mathematics relationship.Now i am going to say something about processor and hyperthreading.So let’s get started.
The Physical Component By Which A Computer Is Mde Which We Can See, Touch And Feel Is Called Computer Hardware Example Ram, Motherboard. ·INPUT DEVICE: These hardware are used to input any data, instruction on command insidea computer device.example keyboard mo9use scanner microphone, webcam etc ·OUTPUT DEVICE:these hardware are used to get any output from a computer system.example: monitor, printer, speaker. ·CENTRAL PROCESSIG UNIT (CPU): This Device Proceses All Instruction Given By A User, And It Also Other Haqrdwqaar Peripherals Example:Microprocessor ·MOTHERBOARD: It is the main electric circuit board which is made by a pcb(printed circuit board).It hods all hardware components and provide interface to those component by which they can communicate with each other. ·MEM…

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 …

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…
