A network architecture in which one more more high powered computers provide resources or services to other computers on the network is called client-server architecture.
Client-server architecture of a computer network is defined as having one or more host computer from a centralized server acts as a service provider for many remote client processors. In a client-server network architecture, Clients are usually PCs, laptops, workstations, or any other personal devices such as smartphones and tablets, while the servers are located elsewhere on the network, usually on more powerful machines. The examples of a client-server network architecture are: web servers, web browsers, FTP (File Transfer Protocol), DNS (Domain Name System). There are many benefits of a client-server network architecture such as a quick and secure data transfer, efficient data delivery to the client devices, and easier management and maintenance.

aos, advance orbital security, designed a security system for a home that would call the police if the master switch to the security system is turned on and if the motion or sound sensor was triggered. which of the following circuits resembles the circuit that aos designed?
Advance Orbital Security would be using Passive Infra Red (PIR) and Active Ultrasonic sound detector in its security system design in order to trigger the security system and call the police upon activation.
Passive Infra Red (PIR) sensor or motion detector security system uses passive infra red that measures changes in the heat energy in the form of electromagnetic radiation radiating from its field of view, and those heat energy are often invisible to human eye. As as soon as the device detected changes in the electromagnetic radiations, it will send out an electric signal from the triggered device to the security system control panel which triggers the alarm sound which then simultaneously sends a cellular signal to the monitoring center at Advance Orbital Security which will then contacted and dispatch the police.
Active Ultrasonic Sound detector in the security system works by emitting ultrasonic sound waves that bounce off objects in its surroundings and return to the sensor with a transducer within the sensor that sends the pulse and receives the echo determining the distance between itself and the target by measuring the time between sending and receiving the signal. As soon as there is a time difference between sending and receiving the echo, it will send out an electric signal, alerting the security system control panel which then send out e cellular signal to the monitoring center at AOS security system which will then dispatch the local law enforcement agency.

Dumpster Diving is a non-technical password attack that is enabled if you write a password on a sticky note and through in the trash. The answer is Dumpster Diving.
Dumpster diving is the practice of rummaging through other people's trash for buried treasure. Dumpster diving is a technique used in information technology (IT) to recover data from discarded items that could be used to carry out an attack or gain access to networks.
Dumpster diving isn't just looking through trash for things like sticky-noted passwords or access credentials that are obviously valuable. A hacker using social engineering tactics may utilize seemingly innocent information, such as a phone book, calendar, or organizational chart, password written over stick notes to help them access the network.
Experts advise businesses to implement a disposal policy that requires all paper, including printed copies, to be shredded in a cross-cut slicer before being recycled, all storage media to be erased, and all employees to be trained on the risks of untracked trash in order to prevent dumpster divers from learning anything valuable from the trash.

what is the main goal of issuing multiple instructions in a clock cycle?
The main goal of issuing multiple instructions in a clock cycle is Multiple issue CPU
It has been examined a number of hardware and software ways to exploit ILP so far. In a pipelined approach, the ideal CPI that we may anticipate is merely 1 We need to consider the possibility of issuing and completing numerous instructions each clock cycle if we wish to lower CPI further. For instance, if we send and process two instructions per clock cycle, our CPI should ideally be 0.5. Multiple issue processors are those that operate in this manner.

the missing lines with the required commands is ip nat inside source static 192.168.2.100 24.1.2.11.
What is IP address?
Any device on a network can be identified by its IP address, which stands for Internet Protocol. IP addresses are used by computers to connect with one another on different networks and the internet.
Private IP internetworks that employ unregistered IP addresses can connect to the Internet thanks to NAT. NAT runs on a device and typically joins two networks. The private (internal network addresses that are not globally unique) addresses are converted into lawful addresses by NAT before packets are sent into another network. NAT can be set up to only advertise one address to the outside world for the entire network. By effectively concealing the entire internal network behind that one address, this capability increases security.
A NAT-configured device has a minimum of two network interfaces: one to the internal network and one to the external network. NAT is typically set up between a stub domain and the backbone at the exit device. NAT converts the locally significant source address into a globally unique address when a packet leaves the domain.
NAT converts a packet's globally unique destination address into a local address as soon as it enters the domain. The translation table for each NAT must be the same if there are several exit points. If NAT is unable to assign an address because there are no more addresses available, it drops the message. Afterward, NAT transmits to the destination an Internet Control Message Protocol (ICMP) host unreachable packet.

Let's take a closer look at how the MAC address table is created and used by an Ethernet switch to facilitate the movement of traffic to its destination.
The switch searches for a match between the destination MAC address of the frame and an entry in its MAC address database if the destination MAC address is a unicast address.
The switch forwards the frame out of the designated port if the target MAC address is listed in the table. The switch forwards the frame out all ports other than the incoming port if the destination MAC address is not listed in the table. It's known as an unknown unicast.
