We investigated a program which is probably used as one component of a bigger password breaking algorithm. We determined that th

e program can input arbitrary N-bit queue and for actual N-bit input also the program output will be always N bits long. Additionally we noticed that the longer program input is, the longer will be the output calculating time. After performing some repeating tests we also determined that the program working time depends only and exactly on input length, not on the input itself.
Finally we fixed some actual working times:



-for N=10 - 10.576 seconds;

-for N=20 - 11.087 seconds;

-for N=25 - 13.544 seconds;

-for N=30 - 27.442 seconds;

-for N=35 - 1 minute 46.059 seconds;

-for N=40 - 9 minutes 10.784 seconds.



Task:



a) Find the program working time for N=50.

b) Please derive the mathematical formula using which is possible to calculate actual working time for arbitrary N.

Match each method of communication with its intended purpose.
Scorpion4ik [409]

Answer:

1. a late breaking news story = to inform

2. a poetry reading = to entertain

3. an advertisement = to persuade

4. a small group assignment = to collaborate

Explanation:

1. A "breaking news" tells people of what is happening in the society. It <em>informs </em>them of the occurrence of an important event such as the plane crash of Kobe Bryant.

2. Poetry reading is meant to touch the attention of listeners. It tries to entertain them through the poem's interesting verses.

3. An advertisement is being shown/displayed in order to convince people to buy a particular product or service.

4. A group assignment allows the members of the group to contribute their ideas together. Such situation is known as "collaboration." They try to brainstorm together towards a common goal.

A network administrator is reviewing a network design that uses a fixed configuration enterprise router that supports both LAN a
tester [92]

Answer:

a modular router

Explanation:

A modular router is a type of router that will provide multiple slots, this will enable the network engineer to either change or increase the number of space the router has.

A layer 3 switch cannot provide a WAN connectivity even though it can increase the number of ports on a router. The concept of PoE capability of any device have nothing to do with the number of ports it has. If the Engineer decides to use another fixed configuration router it will still lead to the same problem in the future because it cannot guarantee or provide the flexibility of future growth adaptation which can be given by a modular router if put in use.

One friend claims that a dual-core system runs at twice the speed as a single-core system; another friend disagrees by saying th
lidiya [134]

Answer:

<u>the first friend</u>

Explanation:

It is important to <em>remember </em>that a core is the brain of the CPU (central processing unit), which means one who has a dual-core is having <em>"a dual brain" </em><em>to process information faster.</em>

Consider also, IT experts often acknowledge that in terms of speed of execution, it is proven that, "dual-core systems" are <em>faster</em> (even twice faster) than a "single-core system". The other friends were wrong because they disagreed with a widely accepted fact that dual-core is faster than single-core; and of course, <em>we know that without them being faster they can't run twice the applications and twice the data. </em>

Therefore, we can make the conclusion that the first friend's response is correct.

Hidden costs of computers into our schools
Gala2k [10]

Answer:

There are certainly many hidden costs, and you need to find them out. I am listing some. The GPU can cost a lot if you are using them for complex computing like in the case of Bitcoin. You need to pay heavy electricity bills as well. And if you want to install the webserver then as well, you need to keep your computer open all the time, and pay a good sum as an electricity bill. Many more hidden costs can be found. And one out of above is used in Schools, the webserver. Some more hidden costs can be Network cost, as the school is big, and you need to connect all through LAN, and at times we also need WAN set up. And these are another hidden cost. Various education licenses come for free, and smart classes cost as well. The video conferencing, VOIP, etc costs as well. Smart classes training by various computer training institute for teachers like one from adhesive.
