CPU: PORTS, BIOS AND CHIPSET

This is the third job, we do it in groups and I have to do ports, BIOS and chipset into the CPU
Ports: a USB port is a standard cable connection interface on personal computers and consumer electronics.
USB port allow stand-alone electronic devices to be connected via cables to a compute sleep-and-charge USB ports can be used to charge electronic devicen even when the computer is swittched off.

BIOS: The Basic Input Output System(BIOS) , is software stored on a small memory chip on the motherboard.
BIOS is sometimes

Chipset: a chipset is a set of electronic
A chipset is a set of electronic components in an integrates circuit that manages the data flow between the processor, memory and peripherals. It is usually found in the motherboard of a computer.
Chipsets are usually designed to work with a specific family of microprocessors.

TIMELINE ABOUT COMPUTERS

This second work is about the timeline about computers.

I´m going to explain you some of the inventions of the computers:

In 1642, Blas Pascal invented the Pascaline.

In 1883, Charles Babbage devised the analytical machine.

In 1941, Conrak Suze invented the electromagnetic programmable computer

In 1944, the first electromagnetic computer was created by Howar Eiken.

In 1976, Apple 1 was invented by Woznak and Jobs.

In 2000, Sony release the PlayStation2.

INFORMATION TECHNOLOGIES

This is my first work, it´s about IT
Tic´s are the specifics terms that stresses the role of unified communications and the integration of telecommunications computers as well as necessary enterprise software, middleware, storage, and audio-visual systems, which enable users to access, store, transmit, and manipulate information.

Some of their advantages are that it causes interest, motivation, interaction, development of the initiative...
Some of their disanvantages are that it causes distractions, dispersion and it is loss of time.

Tic´s offer some tools to have civil competitions: informed citizens, skills of investigation and communications and responsables skills for participations and actions.

It have some irresponsable actions, like comercial, sexuals, embarrasings and ethics situations.
