Answer:
Correct limitation for Attribute Name and value is option
b: Value and name combined must not exceed 400KB
Explanation:
For amazon dynamo db You can have unlimited attribute per item but one attribute cannot exceed 400 kb in size.400Kb is the limit of an item which can be stored in db.
If bigger data is required to store than data is stored some where and links/url to data are stored in the db.
For Item max size is 64KB
Complete question is:
Study the code segment below to see what it will output. Values of x and y will be displayed multiple times during the running of the program, and you might recognize a pattern. From the list of possible outputs listed two (2) are IMPOSSIBLE. Choose the two (2) outputs that are impossible for this code to produce.
x <- 0
REPEAT_UNTIL( x = 3 ){
y <- 0
x <- x+1
REPEAT_UNTIL ( y = 3 ){
y <- y+1
DISPLAY( x + ", " + y)
}
}
NOTE: if the condition is TRUE the loop does not execute. For example if x is currently 3 then REPEAT_UNTIL (x=3) will not execute.

Explanation:
An integer (int) is of two different bytes and each page has 200 bytes in length. What this means is that each row of array A (100 int) will fits perfectly in a page.
(a) For the initial or first array-initialization loop, one column is processed at a time, so a page fault will be generated at every inner loop iteration, with a total of 100*100=10,000 page faults.
(b) And when it comes to the second array-initialization loop, one row is processed at a time, and a page fault is generated at every outer loop iteration, with a total of 100 page faults.
Hence second array-initialization loop, has better spatial locality.
Answer: B. Personal Digital Assistant (PDA).
Although some of the other devices listed may have the capability of allowing the use of a digital pen, the use of the pen will be somewhat unnecessary. Let's take the personal computer and laptop for instance. In a personal computer and laptop we already have a mouse or track pad that can be used to navigate and select objects in the computer.
For the smart television, most smart televisions can actually be operated with gestures or voice command, the use of a digital pen will also not help due to the size of the screens of the televisions.
In the past we had some mobile phones that have a stylus as a pointer. This type of technology has now been change to touch screens that are more effective for the different types of mobile being produced now a days.
Most PDA's come with a screen that requires a small amount of pressure to activate commands. Digital pens also come with different functions that allow the device to draw, record audio, and even shortcut commands for these devices. These digital pens input are then converted by device and translated into computer language.
