FILE ORGANIZATION: It refers to the way of arranging the records in a file which can be accessed in a faster way. The criteria considered in choosing a file organization are: 1) Fast access to single record or collection of related records. 2) Easy record adding/ update/ removal without disrupting. 3) Storage efficiency 4) Redundancy as a warranty against data corruption. The files are generally viewed as • Logical File organization: The groups of fields which are combined to form logical record, which can perform different operations on the file. • Physical file organization: The data which is stored in the form of records can be placed in any storage devices, main memory, secondary memory etc. Types of File Organization: I) Sequential Access File Organization II) Direct Access File Organization III) Index Sequential Access File Organization I) Sequential Access File Organization: 1) All records are stored in a sequential order. 2) That is, the records are ar...

Explain call by value and call by reference with example. Call by value- When a function call is given, a relationship is established between actual and formal parameters. A temporary storage is created for formal parameters to store the data(actual parameters) received as input from calling function. This process of data transfer from actual parameter to formal parameters is known as call by value. Ex: void main() { int a=20,b=30,x; int f1(int,int); ----- x=f1(a,b); ----- getch( ); } int f1(int p, int q) { p=p+p; q=q+q; return(p+q); } Call by reference- When a function is called, the address of variables are passed on to the called function. The parameters receiving the address should be pointer variables. This concept of sending the address of data from calling function to pointer variables in the called function is known as call by reference. Ex: viod main() { int a=10,b=15,c=20; ------ X=f1(&a,&b,&c); ------ getch(); } int f1(int *p...

Network services • File Services- All the data files of an organisation are stored in one place and can be shared by many users. Files can be organized and updated systematically. • Print Services - When Printers available on the Network , multiple users can print to the same printer.
