What is the basic difference between x.509 and pgp in terms of key hierarchy and key trust?

1 answer:

3 0

In terms of key hierarchy, you have to request to a Certification Authority in order for them to issue you an X.509 certificate. On the other hand, you can creat your own pgp.

In terms of key trust, X.509 supports only a sole key owner. It can support only one digital signature to confirm the key's validity. This does not work for pgp.

What is the size of the program counter for an avr that has a 1 kbyte rom capacity?

horsena [70]

Answer:

9 bits

Explanation:

We all recognize 1 K bytes as =1024 bytes.

And the storage medium used for program instructions are the non-volatile flash memories. The MCUs are always 8 bits, and a piece of the instructions revenues two or one 16-bit words. Besides we know program memory magnitude through the device name, and as an instance, the ATmega64x line emanates with 64KB of flash, and the ATmega32x line emanates with 32 KB. And there is nobody like off-chip program memory, and all of the codes that are being implemented by the AVR essentially be on the on-chip flash. However, this restraint is not ever applied to the AT94 FPSLIC AVR/FPGA chips. Also, you must know that AVR is a family of microcontrollers established by ATEL in 1996. It is a Harvard architecture type single-chip 8-bit RISC microcontroller. And it is supposed to be the first microcontroller which applied flash memory for storing the program They are heavily used in embedded systems.

1k byte = 1024 bytes, However, if the program instruction takes 16 bits.

And hence it only wishes 512.

Here and now 512 = 10^9, and henceforth you necessitate 9 bits at minimum.

excluding you can somehow paginate that (such as through one-bit pagination, you will be necessitating only 8 bits and so on.)

Therefore the answer here = 9 bits.

Which of the following is a set of short-range wireless technologies used to share information among devices within about two in

8_murik_8 [283]

Answer:

Option (c) NFC

Explanation:

The NFC Technology is a Wireless Technology which works in the range of 10 cm or less.
NFC stands for Near Field Communications.
The name itself indicates that it a communication mode with the near by objects.
The NFC technology is used in Access Cards, Payment Cards and Mobile Devices etc.
Option (a) IM - Instant Messaging is the instant text messaging technology sends and receives messages over the internet. It is used in Social Media where instant messaging is available. So, option (a) is not correct option.
Option (b) text messaging the technology is the technology in which the text messages are sent over the mobile networks ( in case of text messaging in mobile phones ) or over the internet ( emails, blogging etc). So, option (b) is not correct option.
Option (d) DES is not a short range wireless technology. So, option (d) is not correct.
Option (c) NFC is correct option.

A conventional uniprocessor has __________ .

lys-0071 [83]

Answer:

The correct option to the following question is option (A).

Explanation:

SISD is used in the uni-processors systems which executes an individual instruction streams at a time by which we control an individual memory for the storage of data.

It is the flow or the sequence of an individual data or instructions which controlled on the systems.

Whereas SISD is different from the SMID and it is not used in the Uni-processor systems
