Answer:
- Peripheral devices
Explanation:
Peripheral devices are defined as computer devices which are not the element of the essential/basic computer function. These devices can be internal as well as external and are primarily connected to the computer for entering or getting information from the computer. For example, the keyboards or mouse functions to enter data into the computer for processing and receiving information while the output devices like speakers, projectors, printers, etc. are used to get the information out of the computer.
The arithmetic logic unit (ALU), which performs arithmetic and logical operations.
The control unit (CU), which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.
Answer:
Answer is A. One.
Refer below.
Explanation:
A data flow cannot go directly back to the same process it leaves. There must be at least one other process that handle(s) the data flow, produce(s) some other data flow, and return(s) the original data flow to the beginning process.
Answer:
If all the character pairs match after processing both strings, one string in stack and the other in queue, then this means one string is the reverse of the other.
Explanation:
Lets take an example of two strings abc and cba which are reverse of each other.
string1 = abc
string2 = cba
Now push the characters of string1 in stack. Stack is a LIFO (last in first out) data structure which means the character pushed in the last in stack is popped first.
Push abc each character on a stack in the following order.
c
b
a
Now add each character of string2 in queue. Queue is a FIFO (first in first out) data structure which means the character inserted first is removed first.
Insert cba each character on a stack in the following order.
a b c
First c is added to queue then b and then a.
Now lets pop one character from the stack and remove one character from queue and compare each pair of characters of both the strings to each other.
First from stack c is popped as per LIFO and c is removed from queue as per FIFO. Then these two characters are compared. They both match
c=c. Next b is popped from stack and b is removed from queue and these characters match too. At the end a is popped from the stack and a is removed from queue and they both are compared. They too match which shows that string1 and string2 which are reverse of each other are matched.
Answer:
Alt + F9
Explanation:
The Keyboard shortcut that Stephen can use use to toggle between data and the field codes is Alt + F9. This is in regards to Microsoft Word Fields for both Windows and Mac operating systems. Although ALT + F9 will toggle between these two but for all the fields within the document. If you want to toggle between a single or various fields it would be Shift + F9.
