Software and hardware
1-Computer language and function
When we are comunicate or memorise a sentence or make calculations we use a lot of different symbols, sounds and images. This is known as the binary system.
The smallest unit of formation that we can store in a computer is the bit.(b). Eight bits together form a byte.(B)
ASCII
We give a code to each of the letters of the alphabet, and the characters computers use, so we can store them.
1.1. Computer functions
We use the name hardware for the physical components of the computer system that we use and those that we can touch and move it.
Software or programs refer to the data and the instructions we use to manage that data
Computers carry many functions.
Input of data
Output of data
Storing data
Processing data
2-Computer elements
2.1. Microprocessor
Computer history is very closely Iinked to the deveploment of integrated circuits or chips.
Today microprocesor can have 64 bits at a time
Every time the microprocesor recive impulses
The clock rate sets the pace at wich process are completed.
A microprocesor also depends on its cache memory and the speed of its RAM.
2.2. Memory and units of storage
RAM
CACHE MEMORY
ROM BIOS
Storage devices
2.3. Motherboard and connecting devices
Inside the computer you will find a large board, we call it the motterboard. All the other components of the computer are conected to it.
In addition to the microprocessor and memory motherboard al
mcludes the following components
The IDE, or ATA and SATA
Chipset
Slots
Connecting external devices
Using a expansion of slot in yhe motterboard.
By special conectors in the motterboard
Using the externl ports on the side or back of the computer.
3-Software and operating systems
There are various types of sofware
operating system
Applications
presentations
drawing programs
spreadsheets
word proccesors
dabaste managent tools
programming languajes
Functions of the operating system
h l anages the microprocessmanages the microprocessor

How to keep your system up to date
6-Computer networks
A computer network is a set of equipment, nodes and software connected to each other by means of physical or wireless devices that send and receive electrical impulses, electromagnetic waves
metropolitan area networks
wide are networks
LANs
6.1. Elements in a network
adaptor
network card
hub
switch
transmission medium
6.2. Wireless networks
use travels through space electromagnetic waves to transmit data
6.3. Shared Internet access
using internet connection sharing we can stay in contact all the time.
using a router we can have internet
