Before cellphones are able to be used to browse the internet, play games, record videos and take photos, its main purpose is similar to a telephone, albeit it is more portable. Early cellphones would not have games for you to play, not would it have emails for you to check, read, and reply to. Though ringtones might seem as an acceptable option, early cellphones would also have many selections or even any for you to choose.
Thus, the best option would be (B) contact list, which is necessary for a cellphone to have since the owner would need the number to be able to make a call.
Answer:
D
Explanation:
Not much of a tech person, but protocol then firewall seems the most reasonable.
Answer:
The answer to this question is True.
Explanation:
If we allow every communication this will not be a great idea if we want better security and better productivity.
There will be a lot of spam communications so the productivity and the security will also degrade because of that.
So if we want better productivity and security we have to allow a certain number of connections.
Hence the answer to this question is True.
Shuffle (A[1..m], B[1..n], C[1..m+n]):
Shuf[0, 0] ← True
for j ← 1 to n
Shuf[0, j] ← Shuf[0, j − 1] ∧ (B[j] = C[j])
for i ← 1 to n
Shuf[i, 0] ← Shuf[i − 1, 0] ∧ (A[i] = B[i])
for j ← 1 to n
Shuf[i, j] ← False
if A[i] = C[i + j]
Shuf[i, j] ← Shuf[i, j] ∨ Shuf[i − 1, j]
if B[i] = C[i + j]
Shuf[i, j] ← Shuf[i, j] ∨ Shuf[i, j − 1]
return Shuf[m, n]
The algorithm runs in O(mn) time.
