    1. A hardware packet sniffer can ensure that no packets are lost owing to filtering, routing, or other purposeful or unintentional reasons by inserting directly into the physical network at the proper point.

      A hardware packet sniffer can ensure that no packets are lost due to intentional or unintentional reasons. It is able to log all of the packet traffic data and store for future analysis.

    2. in DNS cache poisoning attacker sniffs the request through Burpsuite or other interception tools and modify it to malicious DNS servers and cache stores that in this way the DNS amplification type of attacks can be performed

      In DNS cache poisoning, attackers sniff the request through applications such as Burpsuite in order to modify it to malicious DNS servers in order to later perform additional attacks can be performed.

    3. Besides this, an attacker may also use sniffing tools to hijack packets by injecting malicious code into the packet itself, which executes once it reaches the target device.

      attacker may also hijack packets by injecting malicious code into the packets itself.

    1. A packet sniffer can be used as a diagnostic tool by network administrators or as a spying tool by hackers who can use it to steal passwords and other private information from computer users.

      Can be used as diagnostic tool, or spying tool.

    1. DE9 interface

      The RS232C DE-9, often mistakenly referred to as a DB-9 port used to be the industry standard for serial data transmission. A RS-232 serial port was a standard feature of personal computers as it was the preferred way to connect modems, keyboards, mice, external storage and many other peripheral devices.

    2. UART

      A UART (Universal Asynchronous Receiver-Transmitter) is one of the simplest and oldest forms of device-to-device digital communication. It is a communication interface that is set up by default in most embedded devices1. UARTs communicate between two separate nodes using a pair of wires and a common ground2. The UART frame consists of 1 start bit, 1 or 2 stop bits and a parity bit for serial data transfer3. It can be interfaced with a PC (personal computer) using an RS232-TTL converter or USB-TTL converter3.

    1. quantum transducers

      Quantum transducers are devices that convert quantum information from one material system to another without the loss of quantum coherence. In some cases, when a quantum system is capable of generating photons, a transducer converts the available photon to a telecom band and back.

    2. optical frequency combs

      an optical frequency comb is a laser source whose spectrum consists of a series of discrete, equally spaced frequency lines. Frequency combs can be generated by a number of mechanisms, including periodic modulation (in amplitude and/or phase) of a continuous-wave laser, four-wave mixing in nonlinear media, or stabilization of the pulse train generated by a mode-locked laser

    1. .

      Summary: George and Chuck are leaving the lamasery, feeling sorry for the monks who were fooled into thinking that the Mark V computer was a holy oracle. They wonder if the monks will smash up the computer in their anger or quietly begin their calculations again. As they descend the mountain on ponies, they see the beautiful DC3 that will take them to freedom. They continue down the road, singing at first, but eventually fall silent as they take in the eerie mountain landscape. George checks his watch and wonders if the computer has finished its run, and as they look up at the sky, they notice the stars going out.

    2. Summary: George Hanley is working on "Project Shangri-La" with Chuck, a fellow engineer, in a remote monastery in Tibet. The monks there believe that when they list all nine billion of God's names, which they are doing using a computer that George and Chuck have built, God's purpose will be achieved and the end of the world will come. Chuck is worried that when the world doesn't end, they will be blamed for building the computer. George thinks that they should wait until their contract is finished and they can leave.

    3. Summary: Dr. Wagner is surprised by the unusual request from the lama to supply a Tibetan monastery with an Automatic Sequence Computer. The lama explains that they are compiling a list of all the possible names of God, and they believe it can be done in less than 15,000 years with the help of the computer. The lama also explains the modifications required for the machine to print words instead of numbers. Dr. Wagner agrees to the project, but is worried about the problem of installation and maintenance. The lama assures him they can arrange for transport and provides his certified credit balance. Dr. Wagner also asks about their source of electrical energy, which is a diesel generator providing 50 kilowatts at 110 volts, installed for the motors driving the prayer wheels.
