Why is it important to have at least one backup stored off-site?

How are web design & web development different from each other?

Margarita [4]

Answer:

Developers are people who build a website's core structure using coding languages, while designers are more visually creative and user-focused. Developers use their programming knowledge to breathe life into the designer’s creative vision.

You could think of developers as construction workers, and web designers as architects – both necessary, but different, skill sets.

I hope this helped :D

In this problem we consider sending real-time voice from Host A to Host B over a packet-switched network (VoIP). Host A converts

Minchanka [31]

Answer:

The total time elapsed from the time a bit is created (from the original analog signal at Host A) until the bit is decoded (as part of the analog signal at Host B is 25.11 ms

Explanation:

Host A first converts the analog signal to a digital 64kbps stream and then groups it into 56-byte packets. The time taken for this can be calculated as:

time taken 1= $\frac{Packet Size in Bits}{Bit Rate}$

= (56 x 8) bits / 64 x 10³ bits/s

= 7 x 10⁻³s

time taken 1= 7 ms

The transmission rate of the packet from Host A to Host B is 4 Mbps. The time taken to transfer the packets can be calculated as:

time taken 2= (56 x 8) bits / 4 x 10⁶ bits/s

= 1.12 x 10⁻⁴ s

time taken 2= 112 μs

The propagation delay is 18 ms.

To calculate the total time elapsed, we need to add up all the time taken at each individual stage.

$Time_{total}$ = Time taken 1 + Time taken 2 + Propagation Delay

= 7 ms + 112 μs + 18 ms

= 0.025112 s

$Time_{total}$ = 25.11 ms

How useful is the creation of folders for your computer

aleksandr82 [10.1K]

Depends on your operating system. For any system not Chrome OS, folder creation is an organizational must. Your hard drive stores data sequentially in the form of bits. Whenever you want to access information on your hard drive, the drive has to, much like an array in programming, run through all the data until it comes across the desired file. This, as you could probably imagine, is cumbersome. We, as the users, have the luxury of not having to deal with that kind of information acquisition. We can create folders and directories into which we can place files. The reason I mentioned Chrome OS earlier, was because Chrome OS stores just about everything in the cloud. There isn't any real need to create directories on a Chrome system because all of that data can be managed and stored on Google's servers, as opposed to in files and organized by yourself.

How can development in ICT be utilized to speed up the development and integration efforts

valina [46]

Answer:

Research question 1:

How do exposure to and use of ICTs in school affect future employment?

The impact of ICT use in school and student exposure to ICTs, and the nature of use and exposure, on student employability in developing has not been well documented. Tracer studies of the impact of ICTs on further study and employment would be useful, as this could be a useful additional measure of educational quality, beyond standardized testing results.

Research question 2:

What is the impact of ‘computer-literacy’ instruction in schools?

In most circumstances in LDC schools, ICTs are used almost exclusively to provide instruction in “computer literacy’. Emerging research from OECD experience suggests such instruction may not be a productive use of time or resources – is this true in LDCs?

Research question 3:

What is the gender impact of ICTs in education on access, use of, attitudes toward, and learning outcomes?

Studies of the potential differential impact of ICT use by gender on student access to learning in a variety of LDC contexts need to be done.

Research question 4:

How can ICTs be used to present, comment on and discuss student work, and what are the implications of such impact?

The effects of using ICTs to present and discuss student work are not well researched.

Research question 5:

Are some school subjects better suited for ICT integration than others?

Given that access to ICTs in schools is quite limited, it would be useful to know if certain ICT applications are better suited to use in certain school subjects and others and, if so, how ICTs can be utilized to aid teaching and learning in such subjects.

Ssume the following variables contain the values shown: numberRed = 100 numberBlue = 200 numberGreen = 300 wordRed = "Wagon" wor

brilliants [131]

Answer:

numberRed = numberBlue = FALSE
numberBlue > numberGreen = FALSE
numberGreen < numberRed = FALSE
numberBlue = wordBlue = ILLEGAL
numberGreen = "Green" = FALSE
wordRed = "Red" = FALSE
wordBlue = "Blue" = FALSE
numberRed <= numberGreen = TRUE
numberBlue >= 200 = TRUE
numberGreen >= numberRed + numberBlue = TRUE
numberRed > numberBlue AND numberBlue < numberGreen = FALSE
numberRed = 100 OR numberRed > numberBlue = TRUE
numberGreen < 10 OR numberBlue > 10 = FALSE
numberBlue = 30 AND numberGreen = 300 OR numberRed = 200 = FALSE

Explanation:

THESE RESULTS ARE VERIFIRED.....
