CONFIGURATION SECTION
CONFIGURATION SECTION
This section is optional. It describes the Computer sy tern used for compiling the program and for executing it. For the purpose there are two paragraphs in thh section.
SOURCE-COMPUTER.
OBJECT-COMPUTER.
The purpose of the former is to give the name of the computer to be used for program compilation and the later is for the one to be used for its executiQn. Being paragragh names, it must be written starting in Margin-A and immediately followed with a period. The entry with in each para is to be the name of the computer system. it is used only for documentation and as such anything can be written within these paras.
SOURCE-COMPUTER. IBM-PC
OBJECT-COMPUTER. IBM-PC
These are the only two entries within the CONFIGURATION SECTION. It should be followed with INPUT-OUTPUT SECTION as follows:
ENVIRONMENT DIVlSIN
CONFIGURATION SECTION.
SOURCE-COMPUTER.IBM-PC.
OBJECT-COMPUTER.IBM-PC.
INPUT-OUTPUT SECTION.
There is another optional paragraph in the CONFIGURATiON SECTION named SPECIAL-NAMES.
INPUT- OUTPUT SECTION
This section is a must to be given if the user is using any file within his program for the purpose of input or output e.g., if he is using a disk file for reading the data and printing it on the printer, he has to use this section to describe these files. This section has two paragraphs:
FILE-CONTROL
• 1-0-CONTROL
This Para can be skipped i7the user does not wish to use any file in his program. A simple program segment is given below:
1NPUT-OU’TPUT SECTION
FILE-CONTROL
SELECT MARKS-FILE ASSIGN TO DISK
ORGANIZATION IS LINE SEQUENTIAL
ACCESS IS SEQUENTIAL
FILE STATUS IS STA’US-C0DE
SELECT RESULT-FILE ASSIGN TO PRINTER. 1-0-CONTROL
SAME AREA FOR
MARKS-FILE
RESULT-FILE
Data Division also has two main sections:
1. The FILE SECTION, as the name indicates, is used to describe the format of data in all the files, whether input or output files. This section is optional. If the program is not using any file this section can be skipped. It must have entries for all the files being used.
2. The WORKING-STORAGE section on the other hand is used to define th data fields required over and above the ones defined in the FILE SECTION. These may be required to stor some intermediate working values or some constants used in the program.

Functions of CPU in a Computer?
Functions of CPU in a Computer?
All the arithmetic operations, taking decisions and control of all computer devices is done by central processing unit. It comprises of an arithmetic-logic section for computations and a primary storage section for holding the instructions and related data for processing. It is divided into three parts.
Arithmetic Logic Unit ( A.L.U.)
It does all the calculations and maes decision on the given information. It is that part of the, central processing unit that performs ai*hmetic and logic operations. This comprises of a number of accu mulators or registers. A register is placed within the A.L.U. where instructions or data are held temporarily.
Control Unit (C.U.)
It controls all the computer devices. It interprets source information to target information. It controls input and output devices and also memory units. It is that part of the processor which is responsible for controlling sequence of operations. The important function of control unit in the modern computer is that
input—output time-sharing.
Temporary Storage Unit (T.S.U.)
Computer stores all the data and inforamtion in the temporary storage unit to access it randomly. Whenever we want to receive any information from the computer memory it will give us randomly. When
electric power will be switched OFF, every thing stored in temporary storage unit will wash off.

algorithm to find the sum of natural numbers
algorithm to find the sum of natural numbers
ALGORITHM is a prescribed set of well—defined unambiguous rules or process for the solution of a problem in a finite number of steps. Commonly used as integral parts of computeçprograms. This algorithmic language is designed for expressing algorithms.
Algorithm Steps:
1. Initialize total marks and total passed to ZERO.
2. Take marks of next students.
3. Add 1 to total passed.
4. Add 1 to total boys.
5. Print out total passed. -
6. STOP

It is a device that produces machine readable output, such as paper tape, either
manual keyboard depressions or from data already recorded in some other code.
(b) FlipJIop
A device or circuit containing active elements capable of assuming either one of
stable states at a given time. Synonymous with toggle.
(c) Clock Circuit’
The circuit used in the timing device that generates the basic periodic signal used
control the timing of all operations in a synchronous computer.

Circuit formed in a single piece of the substrate material, as opposed to a hybrid circuit,
which individual (physically separate) circuit components are electrically interconnected to form the final circuit is called Monolithic Integrated Circuit.
(e) Debugging
