Hardware is the part of the computer that we can touch

CPU

the CPU (central processing unit) is a big, geern plastic board with a lot of chips and many other eletronic components mounted on it

memory

Memory stores information.
There are several types of memory in a computer:
Fixed memory
Usually located inside the computer. Hard drive: Also called a "hard disk," this is a set of rigid disks with a magnetic surface.
Stores all programs and files.

GRAPHICS CARD

Graphics card

The graphics card looks similar to the RAM. It is also a green plastic card with chips. It defines the format of the graphics and helps the processor to process the graphics faster. We need a powerful graphics cards to play video games, to watch movies and for graphic design.

Peripherals are elements of comunication between the computer and the outside world. ENTRY PERIPHERALS: Entry GRAFI peripherals give information to the computer. RUB EXIT PERIPHERALS: THe computer UNIT uses exit peripherals to give information to us or to an actuator. UDEA A peripheral can be both entry and exit; an example is the router to connect to the internet. 1011 The router recieves information from the internet and sends information to the internet.

Software is the part of the computer that we can't touch. It is the logic that the computer follows The programer writtes instructions. A set of instructions is a "program". when we use a program, the computer follows the instructions in the program.

The operating system (OS

There is one OS computer; not more, not less. The OS defines the internal logic for the funcioning of the computer. THe program the OS, we must now which are the components of the hardware and how they are connected. computers had one processor, one application, one floppy disk which was loaded after switching on the computer. The user first loaded the OS, and then the application, the user could. then start to use the application. TODAY'S OS: It is stored in teh hard disc. It can manage multiple applications at the same time. It has a graphic display, so we can interact with the computer using a mouse. It can connect to the internet. There are also various OS for mobile telephones.

THE APPLICATIONS

Sometimes we call them "programs", but any piece of software is a program, incuding the operating sytem. Applications are programs tha we use to do things on the computer; they are our tools. An "application suit" is a group of applications in a package. For example:Open Office, Microsoft or ¡Work'09. Application suites normally include a wordd processor, a spredsheet, a web browser and other. applications. The applications in the suite have a common user interface so that the user can easly learn how to use all of them. The differewnt applications of an application suite can interact with each other. So we can, for example, insert a spreadsheet in a word processor document
