Answer: Coaxial Cable got its name as "coaxial cable" as it has two physical layer of channel in same cable axis.
Explanation: Coaxial cable is the cable that is basically composed of copper and shield of other materials.They have two physical channels and having a insulating layer between them and the outer layer serving as the ground layer. Both the channel of physical layer have the same axis that why it is termed as "coaxial".These cables are commonly used in the cable televisions , sometimes in telephone line etc.
Answer:
<u>720</u> possible PIN can be generated.
Explanation:
To calculate different number of orders of digits to create password and PIN, we calculate permutation.
Permutation is a term that means the number of methods or ways in which different numbers, alphabets, characters and objects can arranged or organized. To calculate the permutation following formula will be used:
nPr = n!/(n-r)!
there P is permutation, n is number of digits that need to be organize, r is the size of subset (Number of digits a password contains)
So in question we need to calculate
P=?
where
n= 10 (0-9 means total 10 digits)
r= 3 (PIN Consist of three digits)
So by using formula
10P3 = 10!/(10-3)!
=10!/7!
= 10x9x8x7!/7!
= 10x9x8
= 720
Answer:
B. Replace the Bluetooth headset with a new pair.
Explanation:
Since all other mobile devices, after receiving the "corporate-wide" OS update, aren't having issues with pairing with Bluetooth headsets, we can safely conclude that the OS update isn't the issue.
To find out if the Bluetooth headset is not the culprit, we can try to pair the mobile device with a different headset. If it pairs correctly, then we can conclude that the old Bluetooth headset might have a fault, or it might need to be disconnected/forget from the device and paired gain.
Answer:
Yes
Explanation:
Depending on the ethernet standard used, the IEEE 802.3 is faster than the WIFI (IEEE 802.11ac).
The ethernet protocol on cabled networks are of different speed based on ethernet standard which ranges from 10 Mega-bits to 100 Giga-bits per second. This protocol is found in the physical layer of the OSI model.
The wifi 802.11ac also known as wifi 5 is a wireless connection medium in the physical layer of the OSI model. It has a range of aggregate speed capacity of 433 mega-bits per second to 6.77 giga-bits per second.
Answer:
char str[5][100]
Explanation:
See attachment for options:
From the options, we can see that the programming language is C language.
The syntax to store an array of m strings with a maximum of n elements in C is:
char array-name[m][n]
In this case:
--- Number of strings in the array
--- Maximum character in each string
Assume the array name is str, the syntax can be expressed as:
char str[5][100]
