  Introduction Take a look at the front and back of your computer case and count the number of  buttons ,  ports , and  slots  you see. Now look at your monitor and count any you find there. You probably counted at least 10, and maybe a lot more. Each computer is different, so the buttons, ports, and sockets will  vary from computer to computer . However, there are certain ones you can expect to find on most desktop computers. Learning how these ports are used will help whenever you need to connect something to your computer, like a new printer, keyboard, or mouse.  Front of a computer case Back of a computer case The back of a computer case has  connection ports  that are made to fit  specific devices . The placement will vary from computer to computer, and many companies have their own special connectors for specific devices. Some of the ports may be  color coded  to help you determine which port is used with a particular dev...

  Introduction The basic parts of a desktop computer are the  computer case ,  monitor ,  keyboard ,  mouse , and  power cord . Each part plays an  important role  whenever you use a computer. Watch the video below to learn about the basic parts of a computer. Computer case The  computer case  is the metal and plastic box that  contains the main components  of the computer, including the motherboard, central processing unit (CPU), and power supply. The front of the case usually has an  On/Off button  and   one or more  optical drives . Computer cases come in different shapes and sizes. A  desktop case  lies flat on a desk, and the monitor usually sits on top of it. A  tower case  is tall and sits next to the monitor or on the floor.  All-in-one  computers come with the internal components built into the monitor, which eliminates the need for a separate case. Monitor The  mo...

  What are the different types of computers? When most people hear the word  computer , they think of a  personal computer  such as a  desktop  or  laptop .

  What is a computer? A  computer  is an electronic device that manipulates information, or data. It has the ability to  store ,  retrieve , and  process  data. You may already know that you can use a computer to  type documents ,  send email ,  play games , and  browse the Web . You can also use it to edit or create  spreadsheets ,  presentations , and even  videos . Hardware vs. software Before we talk about different types of computers, let's talk about two things all computers have in common:  hardware  and  software . > Hardware   is any part of your computer that has a   physical structure , such as the keyboard or mouse. It also includes all of the computer's internal parts, which you can see in the image below. >Software  is any  set of instructions  that tells the hardware  what to do  and  how to do it . Examples of software include web browsers, g...

STACK  DATA  STRUCTURE IN C++ All That You Need To Know About Stack In C++. Stack is a fundamental data structure which is used to store elements in a linear fashion. Stack follows  LIFO (last in, first out)  order or approach in which the operations are performed. This means that the element which was added last to the stack the will be the first element to be removed from  stack. STACK IN C++ A stack is similar to real-life stack or a pile of things that we stack one above the other. As shown above, there is a pile of plates stacked on top of each other. If we want to add another item to it, then we add it at the top of the stack as shown in the above figure (left-hand side). This operation of adding an item to stack is called “ Push ”. On the right side, we have shown an opposite operation i.e. we remove an item from the stack. This is also done from the same end i.e. the top of the stack. This operation is called “ Pop ”. As shown in the above figure, w...
