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.

A computer system requires users to have an access code that consists of a three-digit number that is not allowed to start with zero and cannot repeat digits. How many such codes are possible
Answer:
648
Explanation:
---
Conditions: Not allowed to start with 0 // No repeating digits
---
9 possible ways for first digit (excluding 0, therefore 1-9)
e.g. 123, 234, 567
9 possible ways for second digit (excluding 0 and digit before 1-9)
e.g. 123, 124, 125
8 possible ways for third digit (excluding 0 and condition for second digit 1-9)
e.g. 789 is legit, but 788 is not
Multiply 9*9*8 to get an answer of 648

How do raster graphics, used with CRT technology, work? What kinds of images does this create?
Answer: It is a type of CRT, similar to that of an early oscilloscope. In a vector display, the image is composed of drawn lines rather than a grid of glowing pixels as in raster graphics. ... The beam skips over dark areas of the image without visiting their points.

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.
