PINS 1-8(PORT 1): Each of these pins can be configured as an input or an output.
PIN 9(RS): A logic one on this pin disables the microcontroller and clears the contents of most registers. In other words, the positive voltage on this pin resets the microcontroller. By applying logic zero to this pin, the program starts execution from the beginning.
PINS 10-17(PORT 3): Similar to port 1, each of these pins can serve as general input or output. Besides, all of them have alternative functions:
PIN 10(RXD): Serial asynchronous communication input or Serial synchronous communication output
PIN 11(TXD): Serial asynchronous communication output or Serial synchronous communication clock output.
PIN 12(INT0): Interrupt 0 input.
PIN 13(INT1): Interrupt 1 …show more content…
PIN 18, 19 (X2, XI): Internal oscillator input and output. A quartz crystal which specifies operating frequency is usually connected to these pins. Instead of it, miniature ceramics resonators can also be used for frequency stability [1].
PIN 20(GND): Ground.
PIN 21-28(PORT 2): If there is no intention to use external memory then these port pins are configured as general inputs/outputs. In case external memory is used, the higher address byte, i.e. addresses A8-A15 will appear on this port.
PIN 29(PSEN): If external ROM is used for storing program then a logic zero (0) appears on it every time the microcontroller reads a byte from memory.
PIN 30(ALE): Prior to reading from external memory, the microcontroller puts the lower address byte (A0-A7) on P0 and activates the ALE output. After receiving signal from the ALE pin, the external register memorizes the state of P0 and uses it as a memory chip address. Immediately after that, the ALU pin is returned its previous logic state and P0 is now used as a Data Bus. As seen, port data multiplexing is performed by means of only one additional (and cheap) integrated circuit. In other words, this port is used for both data and address

RAID 1 is only required for two minimum disk drives to implement the mirroring with each other. It has high availability but no data protection. For example, if you delete a file in a mistake, this file also immediately removed from both mirrored disk storage. The same thing also happens if you disk is running by a virus or software bugs, it also can be done in both mirrored copies at the same time. If hackers attack the disk and enter into the disk for stealing the data, they can do both disks.…

Maryrose Steier ATS 113 1/25/2017 Chapter 1: • Explain why television newscasts have weather segments but not climate segments. • Weather changes on a day to day or even an hourly basis. People want to know whether it will be raining, very hot, or sunny and clear skies on a particular day so that they are prepared. Climate however changes very slowly, if it does at all. A climate broadcast would be unnecessary because they would be repeating the same thing for many days and even years.…

1. How does iSCSI handle the process of authentication? Research the available options? iSCSI follows the Challenge Handshake Authentication Protocol initially the initiator sends the request to the system and checks whether to begin the session or not. If the system is preoccupied with the requests, then it denies the request and replies the system is busy or else it allocates the session. iSCSI uses the Challenge Handshake Authentication Protocol and the user can log in using the CHAP user name…

Section 7.1 Question 3 What information is contained in a routing table? A router is a device which connects multiple networks and assists in data transfer between different devices. This communication is achieved by forwarding data packets to the destination port using the information on the routing table. A routing table essentially stores information on how data packets travel in the network. This information is often viewed in a table format. Routing table contains destination-IP address, Network…

RTP is the protocol that supports the transport layer services for real-time applications. Each RTP packet contains a RTP header and a RTP payload that contains a small sample of the voice conversation. The size of the voice sample encapsulated within the RTP packet will depend on the CODEC used. The following diagram shows the RTP stack. Fig. 2.2. RTP stack RTP uses UDP as its basic transport protocol to avoid the retransmission of lost or dropped packets. So that a user would not experiences…

This can be established by disabling non-required system services, to renaming access accounts and resetting passwords. Any organisation network without a properly configured IPS or firewall is an insecure network. In many instances wherein poorly implemented products have been disabled or ignored, after admins got tired of the false positive warnings. Understanding…

Unit 7 Journal Submission One of the most intriguing aspects of cyber threats to cloud computing that I encountered in Unit 7 was the complexity of network security and compliance. Complexity arises because cloud environments are inherently multi-tenant and scalable, which means that security measures must be robust enough to handle diverse and evolving threats (Ots, 2021). I found this interesting because the challenge of securing dynamic and scalable environments is substantial. Unlike traditional…
