Hardware Tips

By
Assembling process
Required components:
1.     System case
2.     SMPS(Switch Mode Power Supply)
3.     Motherboard
4.     RAM(Random Access Memory)
5.     CPU chip (Central Processing Unit)
6.     Optical Disk Drive
7.     CPU fan
8.     Hard Disk Drive
9.     Graphics card
Assembling the Computer is the process of making a completely working system combining various parts of compatible hardware of the computer system.  A computer is said to be assembled when its various hardware components like Hard Disk, Memory, Power Supply, SATA/PATA etc. are connected manually in a proper way so that the system functions smoothly.

Things to Consider:

·         Hold the main board and expansion cards by edges
·         Return the main board and peripherals to
anti-static bags
·         Disconnect the power before working on the system
·         Never place the components above the material that can pass electricity
·         It is advised not to touch in the middle of internal components like processor, motherboard as it can get short-circuit by static electricity.
·         We should use correct type of SMPS for the system as requirement provided by the technical professional.

Step 2: Insert CPU chip into CPU slot and close the socket.

Step 3: Insert CPU fan and Fan wire into motherboard. Make sure screw was tided correctly. 

Step 4: Insert Motherboard into System Case.

Step 5: Insert Optical Disk Drive. Tide the screw.

Step 6: Insert Graphics card into PCI slot while managing Graphics port.

Step 7: Insert HDD in the system case.

Step 8: Insert SMPS in the case and tide the screw.

Step 9: Connect all the cable simultaneously.

Testing connections:
Plug in PSU power cord into PSU and to wall outlet and start computer. Use usual precautions when handling electricity! Test to see the following are running - all 3 fans - case, CPU, PSU, (and video card fan(s) if separate video card installed). Test power button (PC comes on and off) and reset button (HDD LED light blinks once). Test to see all 3 LED lights work - PLED light (power on light that stays on when PC is on), DVD LED light (comes on at start then goes off), HDD LED light (blinks initially).

Put back case left, right and front panels

Screw back case left and right panels with thumb screws. Make sure you get the sidescorrectlay, a case side panel with a window faces the front side of the motherboard giving the components ventilation.

Passing arrays to functions in C programming

By
Like any other variables, we can also pass entire array to a function. An array name can be named as an argument for the prototype declaration and in function header. When we call the function no need to subscript or square brackets. When we pass array that pass as a call by reference because the array name is address for that array. /* Program to illustrate passing array to function */ #include<stdio.h> void display(int) ; /* function prototype */ main( ) { int num[5] = {100, 20, 40, 15, 33, i ; clrscr( ) ; printf (“\n The content of array is \n”) ; for (i=0; i<5; i++) display (num[i]) ; /*Pass array element fo fun */ getch{ } ; } void display(int n) { printf (“\t%d”, n ) ; } Output:     The content of array is 100      20       40       15 3 /* Program to read 10 numbers from keyboard to store these num into array and then c...

Object Oriented Programming

By
Object Oriented Programming Programming paradigm that represents the concept of "objects" that have data fields (attributes that describe the object) and associated procedures known as methods Programming methodology based on objects, instead of just functions and procedures Focuses on data rather than process As individual objects can be modified without affecting other aspects of the program, it is easier for programmers to structure and organize software programs Easier to update and change programs written in object-oriented languages Simula was the first object oriented programming language Eg: C++, Java, etc. Features of OOPS Objects Referred as instance of class Basic run-time entities in an object-oriented system a person, a place, a bank account, a table of data, etc can be an object They occupy space in memory that keeps its state  Each object contains data and code to manipulate the data  Classes Blue print or prototype  which ...

Recursive Function in C programming

By
             If a statement within the body of a function calls the same function, the function is called recursive function. Actually, recursion is a process by which a function calls itself repeatedly until some specified condition has been satisfied. This process is used for repetitive computations in which each action is stated in term of previous result. Many iterative or repetitive problems can be written in this form.                To solve a problem using recursive method, two conditions must be satisfied. They are: 1)       Problem could be written or defined in term of its previous result. 2)       Problem statement must include a stopping condition. /*   An example of recursive function to calculate factorial of a number.*/    #include<stdio.h>    #include<conio.h...
