What is OS (Operating System)?

 

A Flash Drive is a relatively new storage device.  It’s like a mini, portable hard drive!  You plug it into the USB (Universal Serial Bus) port on the front of newer computers and you can save to it! An operating system or OS is a software program that enables the computer hardware to communicate and operate with the computer software.

Microsoft Windows is the most common and used operating system. Apple macOS - Apple Mac operating system. Today, the only Apple computer operating system is macOS. Ubuntu Linux - A popular variant of Linux used with PC and IBMcompatiblecomputers.

 

Google Android - Operating system used with Android compatible phones and tablets. iOS - Operating system used with the Apple iPhone and iPads. Chromium - Google operating system used with Chromebooks. 

What is a Graphics Processing Unit (GPU)?

What is a CPU (Central Processing/Processor Unit)?

The  CPU  (Central Processing  Unit  or  processor)  is  responsible  for  processing  all information  from  programs  run  by  your  computer.  The  ‘clock  speed’,  or  the  speed  at which  the  processor  processes  information,  is  measured  in  gigahertz  (GHz).  This means  that  a  processor  advert ising  a  high  GHz  rating  will  likely  perform  faster  than  a similarly  specified  processor of  the  same  brand  and  age

What is Motherboard ?

Alternatively  referred  to  as  the  mb,  mainboard,  mboard, mobo,  mobd, backplane  board,  base  board,  main  circuit  board,  planar  board,  system board,  or  a  logic  board  on  Apple  computers.  The  motherboard  is  a  printed circuit  board that  is  the  foundation  of or  at  the  bottom  of  the  computer a  computer,  located  on  the  back  side chassis communication  to  the CPU , RAM , .  It  allocates  power  and  allows and  all  other  computer components. 

Motherboard  overview above first  is  a  picture  of  the ASUS P5AD2hardware E  motherboard  with  labels  next  to  each of  its  major  components.

What is RAM (Random Access Memory)?

What is RAM (Random Access Memory)? 

Alternatively  referred  to  as  main  memory,  primary  memory,  or  system  memory, Random  Access  Memory  (RAM)  is  a  hardware  device  that  allows  information to  be  stored  and  retrieved  on  a  computer.  RAM  is  usually  associated  with DRAM ,  which  is  a  type  of memory  module .

Because  information  is  accessed randomly  instead  of  sequentially  like  it  is  on  a CD or hard  drive can  access  the  data  much  faster.  However,  unlike ROM ,  the  computer or  the  hard  drive RAM  is  a volatile  memory  and  requires  power  to  keep  the  data  accessible.  If the computer  is turned off,  all  data contained in RAM  is lost.

What is Software and its Kinds

Parts of Computer

Parts of Computer: 

There are two basic parts that make up a computer.  Hardware: Hardware refers to the physical elements of a computer. This is also sometime called the machinery or the equipment of the computer.

 Examples of hardware in a computer are the kyboard, the monitor, the mouse and the central processing unit. However, most of a computer's hardware cannot be seen; in other words, it is not an external element of the computer, but rather an internal one, surrounded by the computer's casing (tower). 

A computer's hardware is comprised of many different parts, but perhaps the most important of these is the motherboard. The motherboard is made up of even more parts that power and control the computer.

  

In contrast to software, hardware is a physical entity. Hardware and software are interconnected, without software, the hardware of a computer would have no function. 

However, without the creation of hardware to perform tasks directed by software via the central processing unit, software would be useless.  Hardware is limited to specifically designed tasks that are, taken independently, very simple. 

Software implements algorithms (problem solutions) that allow the computer to complete much more complex tasks.  Hardware is basically anything that you can touch with your fingers.
