Computer in Real world

By
        Computer is used in almost every field in developed countries. Industrial advancement, agriculture, defense, education, commerce and business, medicine, tourism, banking etc., are the core areas where computer science is utilized. Today man can communicate from one part of the world to the other part easily, which is an example of the advancement of computer science. Within a minute, man can communicate through telephone, Telex, Fax & TV from one part of the world to the other. Computer helped in banking network also. Your deposited money in a bank of foreign country can be withdrawn using ATM(Asynchronous Transfer Mode) card or Master Card from the other country, and your hand-prints can be sent to any part of the world at great speed.
                  Computer has its application not only in manufacturing, medical research, education and defense,but it is also used in small business offices to handle day-to-day work easily and efficiently. Due to growing importance and numerous applications of computer, it is essential to provide computer education.
                   Computers are used as aids in the study of gravity, flow of electric current, atomic structure, chemical reactions, blood circulation, etc., as textual matter and/or graphical analysis. Computer assist the students in learning and understanding the subject matter easily.
                  Computer is used in developed countries in the study of history, mathematics, geography etc. Similarly mathematics, science and statistics are taught with the aid of computers. Distance learning like "Open University" is another educational application in Europe and America.
                  Students can get University level education with the aid of computers through the "Open University". In 1960's computers were basically applied in research and in 1970's computers were used in industries for process control and quality control. In 1980's , computers were extensively used in education and economic development. At the beginning of 1990's , a new subject has been introduced in education which is called ' Information Technology'.
                     Information Technology is recently developed technology which includes fast processing capabilities of  information and transmitting them from one part of the world to the other. It has tremendously increased the capabilities in telecommunication , television, Telex, fax etc. Staying one corner of the world , one can receive information from any part of the world or he can transmit the information easily with the use of information technology devices.
                   Computer helps in decision making. Sometimes the situations are erroneous in the study of science and mathematics. Complicated mathematical problems and error free scientific processing can be done easily with the help of computers. It is also helps in checking the student's exam paper( Objective types), database management, spreadsheet calculations, record keeping and numerous other activities.

Difference between Binary mode and Text Mode in C programming

By
There are mainly three difference between binary and text mode. They are as follow.               i.       In text mode, a special character EOF whose ASCII value is 26 is inserted after the last character in the file to mark the end of file. But, there is no such special character present in the binary mode. The binary mode files keep track of the end of file from the number of characters present in the directory entry of the file.             ii.       In text mode of file, text and numbers are stored as one character per byte. For example, the number 1234 occupies two bytes in memory but it occupies 4 bytes (one byte per character) in the file. But, in binary mode, the number occupies the number of bytes as it occupies in the memory. Thus,  the above number occupies two bytes in file also in the case o...

CPU (Central Processing Unit)

By
PGA reffered as pin grid array in which pins of CPU are lined up in a straight format. SPGA referred as staggered pin grid array. in which pins of CPU are arranged staggered format. LGA reffered to as Land Grid Array in which pins are available within inside the socket but not in the CPU in other words in line grid array, in CPU ther are no pinsbut insteadpins areattached with in a socket which contact with with the CPU. for e.g. LGA775 socket(no pins on cpu) has better cooling system. better contact and better locking(climbing). LGA1155: Letest generation I socket, also reffered as sandy bridge, Turbo boost overclocking. More resent than LGA 1156 socket. LGA1156: ability to north bridge Doul channel DDR3 optional integreted graphics PCI express LGA1366: hi end core i series socket integreted tiple channal memmory controller external control bridge(HUB) Upgrading CPU: need to check its core suppert check multiprocessor supports or not check on the ...

Types of Functions in C Programming

By
C program has two types of functions: 1. Library Functions 2. User defined functions Library Functions: These are the functions which are already written, compiled and placed in C Library and they are not required to be written by a programmer. The function’s name, its return type, their argument number and types have been already defined. We can use these functions as required. For example: printf(), scanf(), sqrt(), getch(), etc. User defined Functions: These are the functions which are defined by user at the time of writing a program. The user has choice to choose its name, return type, arguments and their types. The job of each user defined function is as defined by the user. A complex C program can be divided into a number of user defined functions. For example: #inlcude<stdio.h> double convert (int) ; /* function proto type */ main() { int c ; /* double d ; */ printf (“Enter temperature in Celsius: ”) ; scanf (“%d”, &c) ; /* d =...
