Hardware and operating systems
Computer language and function
It has the binary system
It has a bit (b), 8 bits form a byte
Examples
Kibibyte
Mebibyte
Gibibyte
Tebibyte
Examples
Kilobyte
Megabyte
Gigabyte
Terabyte
Ich character has a binary code
Computer functions
We use the name hardware for the physical components
Examples
Input--> peripheral devices
Output--> peripheral devices
Storing--> storage devices
Procesing--> microprocessor and the memory
Computer elements
Microproccesor
Clock rate
Sets the pace at wich processes are complete, and it generates electrical impulses
Nowadays the microprocessors can process 64 bits at a time
The power of this also depends on it canche memory and it comunicates with the RAM
RAM
The computer memory is a Ram
When we run an applicationthis goes to the hard disk but it's very slow
Cache memory
Ram cannot work at the same speed as the microprocessor so we instal a cache memory
ROM BIOS
When we turn on our computer it checks our system, and thats the ROM BIOS, it everything is correct the computer goes good
Storage devices
Magnetic disks
It is all we have on the computer or technological objects
Optical discs
The videogames, and the movies
Solid-state memory
A pen-drive, a memory card
Motherboard and connecting devices
If you could open your computer you will find a board, we call it the motherboard and it has got:
Slots, are the components of the computer
IDE, are the things that go to the hard disk
Chipset, that is were the circuits are and it makes the computer work
Input and outputs
Connecting external devices
We use several things but the most important are
Sound card, from the sound for the computer
Graphics card, to see the computer better or worst
Hard disk, for the memory
USB to carry documents there
Devices
Asistente para agregar hardware
Informe sobre nuevos dispositivos
Administrador de dispositivos
Gestor de dispositivos
Software and operating systems
Operating system
Manages the system from the computer
We can create folders, for the things we think that are important
When we want to open a app, we have to give a command
The operating system finds the app on the hard disk, sends a copy of it to the RAM, and loads it onto the screen
The programm is now the active app. It recives data from the keyboard and sends instructions to the microprocessor
When we save the document, the systemfor the free space on the hard disk
To print, you have to click on Imprimir
Functions
Manages the microprocessor
Manages the memory and the storage system
Provides an interface or workng enviroment
Applications
Spreadsheets
Word processors
Presentations
Database management tools
Drawing programms
WIndows operating system
You can install or uninstall programms
Hard disk
Your computer accumulates unnecesary programs and files
They are in small files
And it can repair the computer errors
Saving power
You can make your computer go standby
System updates
Linux operating system
You click the app and you can uninstal
And you can update in ACTUALIZAR
Computer networks
It is a set of computers connected to each other so they can share resources
Elements
Adaptor
Network card
Hub
Transmission medium
Share Internet access
You have to connect the computer to the router
Share resourses in windows
Sharing a printer
You go to impresoras, and you can print what you want
Sharing files and folders
Folders
Compartir seguridad
