How many bytes can be stored in a 4gb flash drive
Answer:
4,294,967,296; theoretically
Explanation:
There is 1024 bytes in a kb, 1024 kb in a mb, 1024 mb in a gb.
So we can use 1024³ as a multiplier to convert gb->byte.
1024³ * 4 = 4,294,967,296 bytes.
However, in practice hardrives always have less useable storage than the quoted amount.

Computer A uses Stop and Wait ARQ to send packets to computer B. If the distance between A and B is 40000 km, the packet size is 5000 bytes and the
bandwidth is 10Mbps. Assume that the propagation speed is 2.4x108m/s
a) How long does it take computer A to receive acknowledgment for a packet?
b) How long does it take for computer A to send out a packet?
The time that it takes the computer to receive acknowledgment for a packet is 0.1667 seconds. The time it takes to send out a packet is 4 x 10⁻³seconds
1 The acknowledgment time for the packetspeed = 2.4x108m/s
Distance = 40000 km,
Time = distance/ speed
= 40000 x10³/ 2.4x10⁸m/s
= 0.1667
The time that it take is 0.1667 seconds.
b. Number of bytes = 5000
5000x 8 = 40000bits
10 mbps = 10000 kbps
10000 kbps = 10000000
packet size / bit rate = 40000/10000000
= 4 x 10⁻³seconds to send a packet out

The algorithm solves the problem
of size n by recursively solving
sub-problems of size n – 1, and
then combining the solutions in
Q(n) time.
Looking at the question on algorithm above, the correct answer is: [tex]O( {2}^{n} )[/tex]
What is algorithm?Algorithm refers to a sequence of instructions that have been well-defined which helps to solve specific problems. Algorithm is used in computation.
The recurrence relation is:
T(n)=2.T(n-1)+c , n>0
T(n)=1, n=0.
Considering the back substitution method,
T(n) = 2kT(n-k)+ 2k-1c+....+20c
Substitute n-k=0
Therefore, we will have:
T(n) = 2nT(0)+ 2k-1c+....+20c
T(n) = [tex] {2}^{n - 1} + 1[/tex]

Answer:accounting
Explanation:
In the 1760s and early 1770s, the British government wanted to raise money by taxing the residents of its colonies in North America. They taxed goods such as sugar and tea and even placed a tax on the printing of documents. These actions angered the colonists, who thought that taxation was unfair since they had no representation in the British government. For this reason, a group of colonists dumped hundreds of chests of tea from Britain into Boston Harbor in 1773, in what became known as the Boston Tea Party. As a result, England passed a series of harsh new laws to punish the colonists, further angering them. The Continental Congress met to voice the colonists' grievances, and eventually, on July 4, 1776, the colonists declared their independence from Britain.
Answer:
Taxes and other laws imposed on the colonies led the colonists to declare independence from England.
Explanation:
During the British government, laws taxes, and other laws increased in the colonies which led the colonists to declare independence from England.

Therefore to raise money and increase taxes and laws colonists declared their independence on 4 July 1776 from Britain.
