Your digital footprint is the trail of 'electronic breadcrumbs' you leave behind when you use the internet. It can include the websites you visit, the photos you upload and your interactions with other people on social networks.
Answer:a) Mainframes, miniframes, PCs, desktop Internet computing, mobile computing
Explanation: The hierarchy of the computers or computing are in the generation is:-
- Mainframe:-designed for the execution of huge data processing , storage and execution.
- Miniframe:-has similar functioning as the mainframe but on smaller scale and version.
- Personal computer(PC):-It is designed for the individual purpose and according the need of the user.
- Mobile computing:-computing that can be done on the mobile phone similar to the computing on the personal computer
- Internet computing:-the computing of the mobile and computer system with the facility of the internet connectivity.
Answer:
Las imágenes son las percepciones visuales que las personas tienen respecto de la realidad que los rodea. Así, a través de la visión, las personas pueden interpretar el contexto en el cual se encuentran inmersos, organizando los distintos componentes de la realidad en la cual desarrollan sus vidas, para poder comprender entonces de qué modo proceder ante las diferentes eventualidades de la vida.
Es decir que, a través de las imágenes, y en conjunto con las demás percepciones sensoriales, los seres humanos pueden contextualizarse en un entorno en el cual se desenvuelven, organizando su vida y su realidad a futuro.
Answer:
B. Symmetric key encryption
Explanation:
Symmetric key encryption is one in which a single encryption key is sent to the receiver so both sender and receiver share the same key. In this type of encryption, the sender uses a particular key to encrypt the data and sends the encrypted data (cipher data) to the receiver and then the receiver uses the same key to decrypt the data.
Public key encryption, or asymmetric encryption uses two keys - a private key and a public key. The public key is know to everyone while the private key is known only to those for whom the message is intended. An application of this type of encryption is in SSL (Secure Sockets Layer) - a protocol for transmitting data privately on the internet.
Private key encryption is not exactly one of the encryption methods but rather, a private key and a public key are used in encryption.
The best option is therefore <em>symmetric key encryption</em>.
