1st - Mechanical Relays, 2nd - Vacuum tubes, 3rd - Transistors
Answer:
1st - Mechanical Relays, 2nd - Vacuum tubes, 3rd - Transistors
Explanation:
From Tubes...
The three main components of a basic triode vacuum tube.
The type of tube used in early computers was called a triode and was invented by Lee De Forest in 1906. It consists of a cathode and a plate, separated by a control grid, suspended in a glass vacuum tube. The cathode is heated by a red-hot electric filament, which causes it to emit electrons that are attracted to the plate. The control grid in the middle can control this flow of electrons. By making it negative, you cause the electrons to be repelled back to the cathode; by making it positive, you cause them to be attracted toward the plate. Thus, by controlling the grid current, you can control the on/off output of the plate.
Unfortunately, the tube was inefficient as a switch. It consumed a great deal of electrical power and gave off enormous heat—a significant problem in the earlier systems. Primarily because of the heat they generated, tubes were notoriously unreliable—in larger systems, one failed every couple of hours or so.
...To Transistors
The invention of the transistor was one of the most important developments leading to the personal computer revolution.The transistor was invented in 1947 and announced in 1948 by Bell Laboratory engineers John Bardeen and Walter Brattain. Bell associate William Shockley invented the junction transistor a few months later, and all three jointly shared the Nobel Prize in Physics in 1956 for inventing the transistor. The transistor, which essentially functions as a solid-state electronic switch, replaced the less-suitable vacuum tube. Because the transistor was so much smaller and consumed significantly less power, a computer system built with transistors was also much smaller, faster, and more efficient than a computer system built with vacuum tubes.
The conversion from tubes to transistors began the trend toward miniaturization that continues to this day. Today’s small laptop PC (or netbook, if you prefer) and even Tablet PC systems, which run on batteries, have more computing power than many earlier systems that filled rooms and consumed huge amounts of electrical power.
What ethical concerns might arise from applying new IT to law enforcement?
Answer:
One ethical concern that might occur is the rise of bias in the police department. It would be possible for a disgruntled or frustrated cop to lean into new IT and be able to take advantage of a past suspect or an "enemy" of theirs such as a neighbor or even a coworker.

Jenny is working on a laptop computer and has noticed that the computer is not running very fast. She looks and realizes that the laptop supports 8 GB of RAM and that the computer is only running 4 GB of RAM. Jenny would like to add 4 more GB of RAM. She opens the computer and finds that there is an open slot for RAM. She checks the other module and determines that the module has 204 pins. What module should Jenny order? a. SO-DIMM DDR b. SO-DIMM DDR 2 c. SO-DIMM DDR 3 d. SO-DIMM DDR 4
A friend has asked you to help him find out if his computer is capable of overclocking. How can you direct him? Select all that apply.
a. Show him how to find System Summary data in the System Information utility in Windows and then do online research.
b. Show him how to access BIOS/UEFI setup and browse through the screens.
c. Explain to your friend that overclocking is not a recommended best practice.
d. Show him how to open the computer case, read the brand and model of his motherboard, and then do online research.
Answer:
1. She Should Order C. SO-DIMM DDR 3
2. a. Show him how to find System Summary data in the System Information utility in Windows and then do online research.
Explanation:
Jenny should order a SO-DIMM DDR3 module.
To determine overclocking capability, access BIOS/UEFI setup and research or check system information.
What is the explantion of the above?For Jenny's situation -
Jenny should order a SO-DIMM DDR3 module since she mentioned that the laptop supports 8 GB of RAM and the computer is currently running 4 GB of RAM. DDR3 is the most likely type that would be compatible with a laptop supporting 8 GB of RAM.
For the friend's situation -
To help the friend determine if his computer is capable of overclocking, the following options can be suggested -
a. Show him how to find System Summary data in the System Information utility in Windows and then do online research.
b. Show him how to access BIOS/UEFI setup and browse through the screens.
c. Explain to your friend that overclocking is not a recommended best practice.
Option d is not necessary for determining overclocking capability, as the brand and model of the motherboard alone may not provide sufficient information.

azure claims there are 54 regions. but when i create my account, i can only see 30 or so. what happened to the other regions?
Explanation:
Some regions may not have the full suite for the utilization of the Microsoft Azure platform or they may possess limited capabilities for them to fully function.
Azure claims there are 54 regions. but when I create my account,one can only see 30 or so as they may not have the capacity to perform that well with respect to other functions.
Infrastructure and services are placed within one latency-defined perimeter in every Azure region. Companies are linked by a specialized minimal-wide system. Because of this structure, Azure services in every location provide the highest level of protection and functionality.
All unavailability zone-enabled locations have an at least three distinct aws regions to provide resilience. When something goes wrong, they maintain your information synchronised and available.
One or maybe more storage arrays with separate power, heating, and networking infrastructure make up each area. The purpose of aws regions is to ensure that even if one region is compromised, the remaining can still provide regional service, bandwidth, and highly available.
