Answer 1

Answer: Devices connected in a Bluetooth network communicate with each other using ultra-high frequency (UHF) radio waves. These are electromagnetic waves with frequencies around 2.4 gigahertz (2.4 billion waves per second). UHF waves of different frequencies are used in microwave ovens, GPS systems and many other devices, White hat hackers employ the same methods of hacking as black hats, with one exception- they do it with permission from the owner of the system first, which makes the process completely legal. ... There are even courses, training, conferences and certifications for ethical hacking. A hub connects multiple computers together in a Local Area Network (LAN). All information sent to the hub is then sent through each port to every device in the network.

Hubs are unable to tell one computer from another, so they receive information on one port and then blindly forward it to all other ports — whether it was intended for those computers or not.

So even though you may only want to send information to one other computer, if you have five total computers on your network, then there will be four other computers receiving data that wasn’t intended for them. Showing results for are Infrared signals are suitable for long distance data communication..

Search instead for are Infra-red signals are suitable for long distance data communication..

Infrared laser systems can also be used for long-range communication (up to about 2.4 kilometres), with a maximum projected data rate of 16 Mbps. ... An infrared transmitting device, either a light-emitting diode (LED) or a laser diode, converts an electrical signal to an optical signal.

Web Browser is a software which is used to browse and display pages available over internet whereas web server is a software which provides these documents when requested by web browsers. ... Web browser sends an HTTP Request and gets a HTTP Response. Web server receives HTTP Request and sends a HTTP Response.

Simple LANs generally consist of cabling and one or more switches. A switch can be connected to a router, cable modem, or ADSL modem for Internet access. A LAN can include a wide variety of other network devices such as firewalls, load balancers, and network intrusion detection.

Coaxial cable, or coax (pronounced /ˈkoʊ. æks/) is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric (insulating material); many coaxial cables also have a protective outer sheath or jacket.

Terrestrial microwave- The most common type of microwave antenna is the parabolic “dish.”A typical size is about 3 m in diameter. The antenna is fixed rigidly and focuses a narrowbeam to achieve line-of-sight transmission to the receiving antenna. Microwave antennasare usually located at substantial heights above ground level to extend the range betweenantennas and to be able to transmit over intervening obstacles. To achieve long-distancetransmission, a series of microwave relay towers is used, and point-to-point microwave linksare strung together over the desired distance. Used in long haul telecommunicationsservice, as an alternative to coaxial cable or optical fiber.

You can implement a firewall in either hardware or software form, or a combination of both. Firewalls prevent unauthorized internet users from accessing private networks connected to the internet, especially intranets

Major innovations made from the establishment of abucus to the 5th computer generation

Answers

Answer:

Cogs and Calculators

It is a measure of the brilliance of the abacus, invented in the Middle East circa 500 BC, that it remained the fastest form of calculator until the middle of the 17th century. Then, in 1642, aged only 18, French scientist and philosopher Blaise Pascal (1623–1666) invented the first practical mechanical calculator, the Pascaline, to help his tax-collector father do his sums. The machine had a series of interlocking cogs (gear wheels with teeth around their outer edges) that could add and subtract decimal numbers. Several decades later, in 1671, German mathematician and philosopher Gottfried Wilhelm Leibniz (1646–1716) came up with a similar but more advanced machine. Instead of using cogs, it had a "stepped drum" (a cylinder with teeth of increasing length around its edge), an innovation that survived in mechanical calculators for 300 hundred years. The Leibniz machine could do much more than Pascal's: as well as adding and subtracting, it could multiply, divide, and work out square roots. Another pioneering feature was the first memory store or "register."

Apart from developing one of the world's earliest mechanical calculators, Leibniz is remembered for another important contribution to computing: he was the man who invented binary code, a way of representing any decimal number using only the two digits zero and one. Although Leibniz made no use of binary in his own calculator, it set others thinking. In 1854, a little over a century after Leibniz had died, Englishman George Boole (1815–1864) used the idea to invent a new branch of mathematics called Boolean algebra. [1] In modern computers, binary code and Boolean algebra allow computers to make simple decisions by comparing long strings of zeros and ones. But, in the 19th century, these ideas were still far ahead of their time. It would take another 50–100 years for mathematicians and computer scientists to figure out how to use them (find out more in our articles about calculators and logic gates).

Four students measured the mass of a piece of metal whose accurate mass is 34.75g. Their results are 34.2g, 33.75g, 35.0g, and 34.69g. Explain whether the results are precise or accurate​

Answers

Answer:

The given data are more precise than they are accurate

Explanation:

From the given measurements, we have;

The accurate mass = 34.75 g

The deviations from the accurate measurement is as follows;

34.2 g - 34.75 g = -0.55 g

33.75 g - 34.75 g = -1 g

35.0 g - 34.75 g = 0.25 g

34.69 g - 34.75 g = -0.06 g

For precision measurement, we find the average deviations as follows;

The sum of the deviations = -0.55 g - 1 g + 0.25 g - 0.06 g = -1.36 g

The average deviation = -1.36 g/4 = -0.34 g

For accuracy measurement, we find the average of the absolute deviations as follows;

The sum of the absolute deviations = 0.55 g + 1 g + 0.25 g + 0.06 g = 1.86 grams

The average absolute deviation = 1.86 g/4 = 0.465 g

Therefore, the magnitude of the average deviation is less than the magnitude of the absolute deviations, therefore, the given data are more precise than they are accurate

For Internet Protocol (IP) v6 traffic to travel on an IP v4 network, which two technologies are used

Answers

Answer:

These technologies are: Dual Stack Routers, Tunneling, and NAT Protocol Translation.

Explanation:

Dual Stack Routers -  This is the process in which a router’s interface is attached with IPv4 and IPv6 addresses

Tunneling -Tunneling is used as a medium to help the different IP versions  communicate with the transit network.

NAT Protocol Translation -  This helps the IPv4 and IPv6 networks communicate with each other since they do not understand the IP addresses of each other since, they are different IP versions.

The two technologies that are used when Internet Protocol (IP) v6 traffic travel on an IP v4 network are datagrams and ipv6.

A datagram can be defined as a transfer unit that is associated with a packet-switched network.

Internet Protocol version 6 (IPv6) is a protocol used for packet-switched inter-networking.

The IPv6 is a protocol used for end-to-end datagram transmission through multiple Internet Protocol networks.

In conclusion, the two technologies that are used when Internet Protocol (IP) v6 traffic travel on an IP v4 network are datagrams and ipv6.

An identifier that allows multiple elements in an HTML document to be
styled in the same way

Answers

Answer:

CSS , (Possibly Divs)

Explanation:

I have picked CSS, and possibly Div's as my main explanation and answer here is why.

CSS - Cascading Style Sheets, this allows you to edit multiple elements in a HTML document, such as the color or any CSS attribute.

If you would like to learn more about CSS, and the multiple options that CSS provides such as Internal Styles, External Styles, lastly In-line styles. I highly recommend the resource "W3Schools".

DIV's - Divs are basically like a container, where you can input styles into this container that can effect those elements such as if I want the background-color, of the div it would effect all the elements inside that div. However, I said this could be a possibility since it isn't CSS where it is styled however you can group these elements to one div. You can also edit the CSS of the Div to effect it.

Today, most film editors manually cut and splice the actual film footage once it arrives.


O True
O False

Answers

The correct answer should be true, as their job is to *edit* the footage.

Answer:

True

Explanation:

edg2021

The film editor is such an important person on a film that he is often hired before the cast and other crew. This editor is responsible for revising the filmed footage until it becomes the finished film. The editor begins by reading the script to get familiar with the story. It is important for the editor to know the script because film scenes are generally shot and edited out of sequence. When footage begins to come in, the editor reviews the footage and production notes provided by the director and production team. These notes contain details about the footage and the director’s comments about the footage. The editor then uploads or transfers the footage to computers in the editing bay and begins editing the footage into finished scenes. The editing bay is the control room with editing equipment, computers, monitors, and sound system where film editors manipulate plot, sound, graphics, and score to produce a well-constructed scene. This is a painstakingly detailed and time-consuming task
