Answer:
Una computadora es una herramienta muy básica para hacer tareas repetitivas de forma más eficiente. Una computadora no es capaz de analizar un problema y obtener una solución.
Explanation:
Answer:
Central Processing Unit
Explanation:
Principle part of any digital computer system
Interntors present an interesting kind of people who think in peculiar ways sometimes. This ability allows them to view certain situations in ways in which other people cannot. Because of this, they can think of new ways of how such situations can be tackled. This is how inventions are born. A person with an inventive mind sees a new situation where he thinks of a new solution how he could improve this situation with his invention.
This process is continued continuously with new generations of inventors seeing and coming back to old situations over and over again, inventing new things along the way.
Answer:
MAC Addresses (Destination and Source MAC address)
Explanation:
A switch has 3 primary functions:
- Forward frames
- Learn addresses
- Avoid loops
An Ethernet frame has the header, data and trailer and there are two specific fields in the header that helps the switch to know where to send data in future transmissions.
- destination MAC address
- source MAC address
every Ethernet frame has this and when the frame hits a switch or any device, any device can look at it ( an Ethernet frame ) and know where it is suppose to go and where it came from.
Every switch has a MAC address table where it stores MAC addresses of different computers on the network.
Example:
When a PC1 sends a frame to PC2 through a switch, the switch looks at the header of the Ethernet frame for the source mac address and adds the source MAC address to its MAC address table and also the port that it came through.
simply put:
A switch looks at the source MAC address to see if it knows it already, if it does. Great! no need to add it again to it's address table.
If it doesn't, it adds it's source address and the port that the frame came from.
This basically how the switch populates its MAC address table.
False because the internet connects with multiple communication networks to exchange information
