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.

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

More registers appear to be a good thing, in terms of reducing the total number of memory accesses a program might require. Give

gulaghasi [49]

Answer:

Following is given the answer step by step:

Explanation:

First of all we will write a program using MARIE that will support the statement: Sum = (A + B) - (C + D). All the necessary comments are given in front of each statement:

Load A # variable A will be loaded

Add B # B will be added to A

Store Temp1 # A + B will be stored in Temp1

Load C # C will be loaded in memory

Add D # D will be added to C

Store Temp2 # C + D will ge stored in Temp2

Load Temp1 # Temp1 will be loaded in the memory

Subt Temp2 # Temp2(A + B) get subtracted from Temp1(A - B)

Store Sum # (A + B) - (C + D) will get stored in Sum.

We can see from above program that memory is accessed 9 times. While if C + D get executed first than memory accesses will be reduced to 7.

Above same program could be written using an architecture of 4 registers:

The program is as follows:

Load R1 , A #A will be loaded into R1

Load R2 , B # B will be loaded into R2

Add R1 , R2 # R2 gets added to R1 and the result is stored in R1 (A + B)

Load R3 , C # C loaded into R3

Load R4 , D # D loaded into R4

Add R3 , R4 # Value in R4 gets added into R3 and R3 becomes (C + D)

#no memory accesses required for this operation

Subt R1 , R4 #R4 (C + D) gets subtracted from R1 (A + B)

#no memory accesses required for this operation

Store Sum # The recent value will be stored into Sum

Here memory is accessed 5 times in total.

What is the difference between password protection and encryption? please answer quick, i cant pass this test for the life of me

sergiy2304 [10]

Answer:Password protection is like locking something in a safe-deposit. It means no one can get to the locked content without knowing the right combination. This method is used on separate documents, folders, and other data the computer's user may want to protect from other people who might have access to the device. The problem is, if someone interested in such content obtains the password or finds a way to open it without it, the content might be revealed despite the owner's efforts to keep it hidden. Unfortunately, there are a lot of ways hackers could obtain the password or hack in without it. For example, it could be obtained with the help of malware, or it might be guessed if the user chooses a weak password. Not to mention, when it comes to PDF documents, the passwords placed on them can be removed using the CMD window or specific.

Password encryption is a step up from password protection. The term can be a tad confusing because, in fact, you cannot encrypt the password itself. Instead, by setting up "password encryption" you are creating a password AND encrypting the contents of the file. In our example (see instructions below), the contents of the user's PDF document are not only password protected, but also encrypted. It is a process during which the content one wishes to keep secret is altered to make it unrecognizable. For example, if it is a text document, letters of each word might be shuffled with additional characters so the words would no longer make any sense. The reverse process is only available if the person who wants to decrypt this data can provide a specific decryption key or a password. In other words, even if the password is removed no one could read the hidden content as it still would need to be decrypted. Of course, it is important to realize you might be unable to retrieve it too if you lose the decryption key, aka, the password.
