Answer:
Periscope
Explanation:
Optical viewfinders use a system of mirrors and prisms like a periscope. These mirrors bounce the image up to the viewfinder and can then be viewed by the eye.
The camera's optical viewfinder is like a periscope in which to compose your image.
What is a periscope?You can see around walls, corners, and other obstructions using a periscope. Periscopes are installed on submarines so that the occupants can see what is happening above the water. A good illustration of the law of reflection in action is a periscope.
Similar to a periscope, optical viewfinders work with a system of mirrors and prisms. These mirrors allow the image to be reflected up to the viewfinder, where it may be seen with the eye.
However, Periscope had already ceased allowing new users to sign up by that point. Six years after it was first made available to the public, Periscope was finally discontinued. Users can still access their old broadcasts by visiting the Periscope website and logging onto their accounts.
Therefore, to compose your shot, use the optical viewfinder of the camera, which functions like a periscope.

What is output?
C = 1
Sum = 0
while (c less than 10):
C = c + 3
sum = sum + c
print (sum)
Answer:
The output of code will be 10
Explanation:
We need to find output of following code:
C = 1
Sum = 0
while (c less than 10):
C = c + 3
sum = sum + c
print (sum)
Solution:
We will check the condition of while loop, if the condition is true, then the statements inside the loop will be executed. Since brackets are not available so, only one statement is linked with while loop.
First while loop will be executed c < 10 (1<10) the condition becomes true, and statement c=c+3 will be executed ( 4=1+3) and then loop condition will be checked (4<10) the condition becomes true, and statement c=c+3 will be executed ( 7=4+3) and then loop condition will be checked (7<10) the condition becomes true and statement c=c+3 will be executed ( 10=7+3) and then loop condition will be checked (10<10) the condition becomes false, so we will come outside loop body and execute: sum=sum+c (10=0+10) and print sum i. e 10
So, The output of code will be 10

The ______ of a function take(s) information into the function from the calling program. Group of answer choices prototype local variables arguments purpose parameters
Answer:
The __arguments ____ of a function take information into the function from the calling program.
Explanation:
The arguments of a function refer to the information or values that are passed into a function when they are called. The argument may be assigned by default. A default argument is automatically assigned by the compiler because the caller of the function does not provide a value for the argument with a default value.

Explanation:
IP Address: 215.200.110.50
The first process is to convert all octets to binary individually.
215 to binary
i.e. to divide by 2 as follows:
NOTE:
rem means (remainder)
215/2 = 107 rem 1
107/2 = 53 rem 1
53/2 = 26 rem 1
26/2 = 13 rem 0
13/2 = 6 rem1
6/2 = 3 rem 0
3/2 = 1 rem 1
1/2 = 0 rem1
Then count the remainders from down to up:
So, 215 of decimal is 11010111 in binary
Converting 200 to binary, we divide 200 by 2 until the quotient is 0
200/2 = 100 rem 0
100/2 = 50 rem 0
50/2 = 25 rem 0
25/2 = 12 rem is 1
12/2 = 6 rem 0
6/2 = 3 rem 0
3/2 = 1 rem 1
1/2 = 0 rem 1
Then count the remainders from down to up:
So, 200 of the decimal is 11001000 in binary
Converting 110 to binary; we divide 110 by 2 until the quotient is 0
110/2 = 55 rem 0
55/2 = 27 rem 1
27/2 = 13 rem 1
13/2 = 6 rem 1
6/2 = 3 rem 0
3/2 = 1 rem 1
1/2 = 0 rem 1
Then count the remainders from down to up:
So, 110 of the decimal is 1101110 in binary
In binary,110 = 01101110
We divide 50 by 2 until the quotient is 0
50/2 = 25 rem 0
25/2 = 12 rem 1
12/2 = 6 rem 0
6/2 = 3 rem 0
3/2 = 1 rem 1
1/2 = 0 rem 1
Then count the remainders from down to up:
So, 50 of the decimal is 110010 in binary
To determine the network ID, we keep the first 25 bits of 11010111.11001000.01101110.00110010 and locked all remaining bits to 0.
Thus, network ID in binary is 11010111.11001000.01101110.00000000
Therefore;
11010111.11001000.01101110.00000000 as a decimal notation = 215.200.110.50
Thus, the four subnet IDs are:
11010111.11001000.01101110.00000000 ⇒ 215.200.110.0 0
11010111.11001000.01101110.01000000 ⇒ 215.200.110.64
11010111.11001000.01101110.10000000 ⇒ 215.200.110.128
11010111.11001000.01101110.11000000 ⇒ 215.200.128.19

Explanation:
Portable devices are those devices that can be moved with ease from one place to another.
Let us look at the devices one by one
Internal Hard Drive
As internal hard drive is fixed inside the system unit of the computer it cannot be moved easily. So internal hard drive is not portable.
External hard drive, Flash drive, CD and DVD are portable as they are not fixed and are compact in size so they can be moved easily.
Hence,
The portable devices are:
External Hard Drive
Flash Drive

Should Manufacturers Include Extra Programs in Operating Systems for Computers and Mobile Devices?
Answer:
Well, it depends. Sometimes the extra programs can be useful or just plain fun, in which case the answer is yes. But extra programs can also sometimes be utterly useless and get in the way, in which case the answer is no.\
The development of software for computers benefits greatly from an operating system.
What is operating systems?Without an operating system, each program would have to contain both its own user interface (UI) and the complete code required to manage all low-level computer operations, such as disk storage, network connections, and other things.
This would greatly increase the size of any application and render software development difficult given the wide variety of underlying hardware available.
Instead, a lot of routine operations, such transmitting a network packet or showing text on a display or other conventional output device, can be delegated to system software, which acts as a bridge between applications and hardware.
Applications can interact with the system in a predictable and consistent manner thanks to the system software.
Therefore, The development of software for computers benefits greatly from an operating system.

In an array-based implementation of a dictionary, if you represent the entries as an array of objects that encapsulate each search key and corresponding value, how many pointers will you use per array entry?
a. 3
b. 4
c. 2
d. 1
Answer:
The answer is "Option C".
Explanation:
Dictionary is a set of unsorted data values, that is used to save data like a map and which contains a key: value pair in comparison to many other types of data, which only carry a specific number as just an element.
If we use Dictionary as an array so, it uses a two-pointer variable, one for hold key, and the second is used to hold its value.
Consider a processor with a 2 ns clock cycle, a miss penalty of 20 clock cycles, a miss rate of 0.05 misses per instruction, and a cache access time (hit time) of 1 clock cycle. Assume that the read and write miss penalties are the same.
a. Find the average memory access time (AMAT).
b. Suppose we can improve the miss rate to 0.03 misses per instruction by doubling the cache size. However, this causes the cache access time to increase to 1.2 cycles. Using the AMAT as a metric, determine if this is a good trade-off.
c. If the cache access time determines the processor’s clock cycle time, which is often the case, AMAT may not correctly indicate whether one cache organization is better than another. If the processor’s clock cycle time must be changed to match that of a cache, is this a good tradeoff?
Assume that the processors in part (a) and (b) are identical, except for the clock rate and the cache miss rate. Assume 1.5 references per instruction (for both I-cache and D-cache) and a CPI without cache misses of 2. The miss penalty is 20 cycles for both processors.
Answer:
a) 4 ns
b) 3.6 ns
Explanation:
Given that
Miss penalty = 20 * 2
Miss rate = 0.05
Clock cycle = 2 ns
Hit time = 1 * 2
The Average Memory Access Time or AMAT is found by using this formula
AMAT = Hit time + Miss rate × Miss penalty
Substituting directly for the values, we get
AMAT = 2 + [0.05 * (20 * 2 ns)]
AMAT = 2 + (0.05 * 40)
AMAT = 2 + 2
AMAT = 4 ns
b) given that
Miss rate = 0.03
Hit time = 1.2 * 2
Miss penalty remains the same = 40
AMAT = (1.2 * 2) ns + [0.03 * 40] ns
AMAT = 2.4 ns + 1.2 ns
AMAT = 3.6 ns
Considering that the AMAT is 3.6, we can say that it is a good trade-off.
c) CPU time = Clock cycle * IC * (CPIideal-cache + cache stall cycles per instruction)
CPU time
(a) = 2 ns * IC * (2 + 1.5 * 20 * 0.05) =
CPU time = 2 * IC * (2 + 1.5)
CPU time = 2 * IC * 3.5
CPU time = 7 * IC
(b)
CPU time = 2.4 ns * IC * (2 + 1.5 * 20 * 0.03)
CPU time = 2.4 * IC * (2 + 0.9)
CPU time = 2.4 * IC * 2.9
CPU time = 6.96 * IC
The CPU times we calculated in parts (a) and (b) are nearly the same. Thus, we can conclude that, doubling the cache size to improve the miss rate at the expense of stretching the clock cycle results in virtually no net gain.
