Yet another variation: A better packet switched network employs the concept of acknowledgment. When the end user’s device receiv

es a packet correctly it sends an acknowledgment to the sender. Here too, a packet is received correctly with probability p, but the sender keeps sending copies of a given packet until a copy is correctly received (signaled by acknowledgment). Let random variable N be the number of times the same message packet is sent. a) Find the PMF PN (n). b) To avoid excessive delays (too many repeated transmissions of same packet), it is required that the network maintain P[N < 4] > 0.95. Find the minimum value of p that will satisfy this requirement

Discuss the core technologies and provide examples of where they exist in society. Discuss how the core technologies are part of
Vika [28.1K]

Answer:

Part A

The core technologies are the technologies which make other technologies work or perform their desired tasks

Examples of core technologies and where they exist are;

Thermal technology, which is the technology involving the work production, storage, and transfer using heat energy, exists in our refrigerators, heat engine, and boilers

Electronic technology is the technology that involves the control of the flow of electrons in a circuit through rectification and amplification provided by active devices. Electronic technology can be located in a radio receiver, printed circuit boards (PCB), and mobile phone

Fluid technology is the use of fluid to transmit a force, provide mechanical advantage, and generate power. Fluid technologies can be found in brakes, automatic transmission systems, landing gears, servomechanisms, and pneumatic tools such as syringes

Part B

The core technologies are the subsystems within the larger systems that make the larger systems to work

The thermal technology in a refrigerator makes use of the transfer of heat from a cold region, inside the fridge, to region of higher temperature, by the  use of heat exchange and the properties of the coolant when subjected to different amount of compression and expansion

The electronic technologies make it possible to make portable electronic devises such as the mobile phones by the use miniaturized circuit boards that perform several functions and are integrated into a small piece of semiconductor material

Fluid technologies in landing gears provide reliable activation of the undercarriage at all times in almost all conditions such that the landing gears can be activated mechanically without the need for other source of energy

Your organization recently deployed a Windows domain controller with Active Directory. All the domain OU users need to run the s
liberstina [14]

<u>Normally windows end user can login 3 ways as follow:</u>

1. End user can Login as local account where user has not connected or even connected to local Area network LAN.

2. Next user can login into cloud accounts nothing but hot mail  accounts

3. Login to windows domain controller where end user should connect to LAN.

Purpose of installation of Windows domain controller with Active Directory is to keep trace and keep log history activities.

Due to windows domain controller with Active Directory end user desktop or laptop has control on software access also.

Every time when end user login on windows domain controller a small modified is executed whenever is required. It is not going effort the workstation performances.

Note: - Domain severs should be POWER on first.
