Emma & Sofii Software is: a collection of instructions that tell the computer what to do, instructions that can be ‘run’ on a computer. Software is not a physical thing.An operating system such as Windows XP or Mac OS X, applications such as Microsoft Word, and the instructions that control a robot are all examples of software.
Example: skype,word, picasa ,Mozilla firefox, exel, flash player. Analogy: Your hardware is all of the parts that make up your body: bones, muscles, skin, blood, etc. Link: http://www.igcseict.info/theory/1/hwsw/
Hardware is: the physical parts that you can touch and see in the computer system.
Examples: Computer,Laptop,CD,Pen Drive,Scanner, etc. Analogy: Your software is all of your thoughts and mental processes: these are the instructions that tell your physical body what to do

Hardware Hardware is the things that you can touch physical the computer like the motherboard, a CPU, keyboard and a monitor An analogy hardware your hardware is all of the parts that make up your body: bones muscles, skin, blood etc.
Software Software is not a physical thing (but but it can of course be stored on a physical medium such as a CD-ROM), it is just a bunch of codes. On analogy your software is all of your thoughts and mental processes: these are the instructions that tell your physical body what to do An operating system such as Windows XP or Mac OS X, applications such as Microsoft Word, and the instructions that control a robot are all examples of software
The Difference between Hardware and Software Computer hardware is the physical components that make up the computer system. Hardware is useless without software to run on it. Software is instructions that tell computer hardware what to do. Software is useless unless there is hardware to run it on. For a computer system to be useful it has to consist of both hardware and software. On a analogy Your physical body cannot function without your thoughts. And your thoughts need a physical body to exist within Google imรกgenes, http://www.igcseict.info/theory/1/hwsw/index.html,

CPU: The CPU is the 'brain' of the computer. It is the device that carries out software instructions. The Pentium processor made by Intel is an example of a CPU.
CPUs usually plug into a large socket on the main circuit board (the motherboard) of a computer. They get very hot when they are operating so usually have a large fan attached to their top to keep them cool.
The speed of a CPU is measured inHertz (Hz). The speed generally corresponds to the number of actions the CPU can perform every second. • •
1 Megahertz (MHz) is 1,000,000 (1 million) Hertz 1 Gigahertz (GHz) is 1,000,000,000 (1 billion) Hertz
A typical, modern, fast CPU runs at around 2.8GHz. That means it can perform almost 3 billion actions everysecond!
Main Memory: Any data or instructions that are to be processed by the CPU must be placed into main memory (sometimes known as primary storage).
RAM: Random Access Memory (RAM) is the part of the computer that temporarily stores the instructions that the computer is running, and the data it is processing.
RAM is a volatile storage device. This means that if the computer’s power is turned off the contents of RAM disappear and are lost.
RAM, like the CPU, also plugs in to sockets on the motherboard.
When a computer is in use, its RAM will contain‌ The operating system software The application software currently being used Any data that is being processed. ROM: Read-Only Memory (ROM) is used in most computers to hold a small, special piece of software: the 'boot up' program.
This software runs when the computer is switched on or 'boots up'. The software checks the computer’s hardware and then loads the operating system.
ROM is non-volatile storage. This means that the data it contains is never lost, even if the power is switched off.

What is Hardware? •
Hardware is the physical part of the computer system –the parts that you can see and touch like a Matherboard, a CPU, a keyboard, and a monitor are all items of hardware.
An analogy… Your hardware is all of the parts that make up its ¨body¨ An analogy…your hardware is all of the parts that make up its ¨body¨
WHAT IS SOFTWARE? •
Software is known as the logical equipment or software of a computer system, comprising the set of logical components. Is the programs in the computer you can´t touch. They can be: Mac, Windows Vista and Penguin.
•
Read- only memory or ROM is a form of data storage in computers that you put, and other electronic devices that cannot be easily altered or reprogrammed.
•
Random Access Memory or RAM is a form of data storage that can be accessed randomly at any time, in any order and from any physical location in contrast to other storage devices, such as hard drives, where the physical location of the data determines the time taken to retrieve it
•
A central processing unit (CPU), also referred to as a central processor unit, is the hardware within a computer that carries out the instructions of a computer program by performing the basic arithmetical, logical, and input/output operations of the system.
GooGle ImaGes HARDWARE:Is a physical part of the computer. That means you can touch it. EX.:Key Board, Mouse, CPU, Monitor, Etc. SOFTWARE:Is a non physical part of the computer that you cant touch. Only clicking with the mouse. EX.: Google, Mozilla Firefox, The Microsofts, Facebook, Games, Etc.
Rom: ROM - Read Only Memory ROM is an internal memory in the computer which is used to store critical information required by the computer like booting programs. They are prerecorded and are read only.
http://questions.civicvoice.com/q7144__Defin ition_of_RAM_and_ROM.html Ram: RAM - Random Access Memory RAM is another form of internal memory. RAMs are used to store temporary programs that are currently being executed. They come in large sizes of 4GB's and higher. They are accessible and can be changed.

How Does it Work? •
The CPU sits in the motherboard as the central unit. All of the other hardware components and programs installed on the system must go through the CPU before their function can be carried out. The CPU's job function is important and enormous in scale. When a function, program or piece of data is called, the CPU pulls it from Random Access Memory (RAM) and any other hardware in order to process it. The CPU then reads the instructions associated to the task before sending it back to RAM. The instructions that the CPU receives pertains to calculations and data transportation. The system bus is the
trail that the data must travel before it is executed. It is the CPU's job to make sure that the data is guided through the system bus to be processed by the CPU and then on to the next step. With every stop on the system bus, the CPU makes sure that the data gets there in the correct order. •

Hardware: Is the physical part of the computer system – the parts that you can touch and see. Software: is a collection of instructions that can be run on a computer. These instructions tell the computer what to do. CPU function: CPU(central processing unit) is a brain of computer, It processes the data using the registers inside the CPU. A CPU is like a light switch and has two basic functions OFF and ON. which brings us to binary all those 0's and 1's the only language the CPU understands the 0 being OFF and the 1 being ON there are millions of switches inside the CPU moving from OFF to ON millions of times a second processing all the information you give it. http://wiki.answers.com/Q/What_is_CPU_function
Rom:
Is a class of storage medium used in computers and other electronic devices. Data stored in ROM cannot be modified, or can be modified only slowly or with difficulty, so it is mainly used to distribute firmware (software that is very closely tied to specific hardware, and unlikely to need frequent updates). http://en.wikipedia.org/wiki/Read-only_memory Ram:
AN ANALOGY: OUR BONES, MUSCLES, SKIN, ETC. ARE LIKE THE HARDWARE. WE CAN TOUCH THEM.
is a form of computer data storage. A random-access device allows stored data to be accessed directly in any random order. In contrast, other data storage media such as hard disks, CDs, DVDs and magnetic tape, as well as early primary memory types such as drum memory, read and write data only in a predetermined order, consecutively, because of mechanical design limitations. Therefore the time to access a given data location varies significantly depending on its physical location. OUR THOUGHTS ARE INDISPENSABLE BECAUSE THEY TELL THE PARTS OF THE BODY WHAT TO DO. THIS COULD BE THE SOFTWARE.
IN CONCLUSION, YOUR SOFTWARE IS ALL OF YOUR THOUGHTS AND MENTAL PROSSESES: THESE ARE THE INSTRUCTIONS THAT TELL YOUR PHYSICAL BODY WHAT TO DO .
