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…

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 …

OPERATING SYSTEM- AN INTERFACE?

ALL ABOUT OPERATING SYSTEM
An operating system is program that acts as an interface between the user and the hardware of the computer.  It also manages the components of the machine such as processor management, disk resource management, input output files, devices etc.
The operating system can be classified on various parameters. In this section we will learn the classification of the operating system based on the number of user and the number of task performed by operating system that run simultaneously on the computer.
So lets begin CLASSIFICATION BASED ON THE NUMBER OF USER
Based on the number of people accessing the computer, the operating system can be classifiednamely in two types namely single user or multi user.As shown in list below
SINGLE USER :-in this type of operating system only one users can access the resources of the operating system at a time.Example of single user include dos and microsoft windows
MULTI USER :- in this type of operating system more than one user can simult…

FORMATS OF FILESYSTEM IN COMPUTER TECHNOLOGY

FILE SYSTEM AND FORMATING
In this post i am going to teach you about various types of file system and formating used in computers. So lets start.
The file system dictates how information is organized on the disk.For example, the file system determines hjow large the allocation unit, or storage unit, the file is.
The following sections introduce the different file systems available and the os’ s that support them.
The FAT FILE SYSTEM– the file allocation table (fat) file system has been the most popular file system up until the last few years.The file system is designed for the small disk and simple folder structures.
it resides in the beginning of the system. It keeps two copies of the data in its table as back up so that if any copies become corrupted it can cure that corruption.
The file allocation table along with the root folder should be kept on fixed position so that boot files can be perfectly located.The file allocation table (fat) file system has been the most popular file system …
