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.
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.

A user is redesigning a network for a small company and wants to ensure security at a reasonable price. The user deploys a new application-aware firewall with intrusion detection capabilities on the ISP connection. The user installs a second firewall to separate the company network from the public network. Additionally, the user installs an IPS on the internal network of the company. What approach is the user implementing
"Layered approach" will be the appropriate response.
The method that divides the OS into multiple layers, is a layered approach. The latter empowers application developers to modify their internal functions as well as enhances adaptability.The network idea throughout this method is generally separated into multiple levels and a certain responsibility or activity is delegated to every other layer.
Thus the above is the right answer.

advantage of computer
Explanation:
Computers help increase user productivity, and users become more productive at everything you do on the software running on the computer with a good understanding. For instance, when you have work on an Excel worksheet with a basic understanding, you can create, edit, delete, store, calculation, and print documents and letters. With all pre-existing technologies, all of these things were either impossible or much slower.One of the most useful advantages of computers is able to store and access vast amounts of data, which can be retrieved in the future. For example, a computer system and devices like eBook readers have enough storage capacity as they can store hundreds or thousands of books. Also, you can store movies, pictures, songs digitally, and documents on the computer, and can quickly find data accordingly and share information between devices. It reduces plastics and paper requirements that are used to make non-digital versions of the media.A computer has the ability to connect you to the network or the Internet. Once you connected, you can search for any type of information and can download audio, video, movies, documents, and more.Computers help you to connect with your friend, family, or other relatives with long-distance through e-mail and social networking.
