likoan [24]

Hi!

The mouse and the keyboard are <em>input devices. </em>By using them, we can input data which will give us a (hopefully) desired output!

For example...

Just by using my keyboard to type, I'm inputting data in the form of ASCII characters and symbols.

By using my mouse to click on an area so I can move this sentence on a new line, I had to input a request to do such!

Hopefully, this helps! =)

You have a notebook computer and wish to connect to an IEEE 802.11ac wireless network. The computer does not have a built-in WLA

BARSIC [14]

Answer:

Wireless USB 2.0

Explanation:

USB ports are available in all modern notebook computers. This makes the wireless USB 2.0 adapter a capable option to solve the network issue.

Wireless USB 2.0 can send 480Mbit/s and 110Mbit/s at a 3meters and 10 meters respectively, it frequency ranges from 3.1GHz to 10.6GHz.

In cases where the internal wireless card is faulty or the computer does not come with a wireless chip inside, the Wireless USB 2.0 is the right option for you to be able to connect over a network efficiently.

Fifty-three percent of U.S households have a personal computer. In a random sample of 250 households, what is the probability th

aleksley [76]

Answer:

The correct Answer is 0.0571

Explanation:

53% of U.S. households have a PCs.

So, P(Having personal computer) = p = 0.53

Sample size(n) = 250

np(1-p) = 250 * 0.53 * (1 - 0.53) = 62.275 > 10

So, we can just estimate binomial distribution to normal distribution

Mean of proportion(p) = 0.53

Standard error of proportion(SE) = $\sqrt{\frac{p(1-p)}{n} }$ = $\sqrt{\frac{0.53(1-0.53)}{250} }$ = 0.0316

For x = 120, sample proportion(p) = $\frac{x}{n}$ = $\frac{120}{250}$ = 0.48

So, likelihood that fewer than 120 have a PC

= P(x < 120)

= P( p^ < 0.48 )

= P(z < $\frac{0.48-0.53}{0.0316}$ ) (z= $\frac{p^-p}{SE}$ )

= P(z < -1.58)

= 0.0571 ( From normal table )

A. Assume a computer has a physical memory organized into 64-bit words. Give the word address and offset within the word for eac

Galina-37 [17]

Answer:

Check the explanation

Explanation:

For 9th byte , it is from 8*8 bit to 9"8th bit so each word consists of 64 bits , to find word address u have to divide 8*8 by 64.

Offset within word = 9*8modulo 64.

For 27th byte , word address = 8*27/64.

Offset within word = 27* 8 modulo 64

For 21th byte , word address = 8*31/64

Offset within the word = 31*8 modulo 64

For 120 , word address = 8*120/64

Offset within the word = 120*8 modulo 64.
