Answer:

Apache Hadoop

Apache Hadoop is a collection of open-source software utilities that facilitate using a network of many computers to solve problems involving massive amounts of data and computation. It provides a software framework for distributed storage and processing of big data using the MapReduce programming model.

Answer:

Apache Hadoop.

Explanation:

Apache Hadoop is a open source program that uses map reduce programming process to allocate storage and processing of big data computation. It uses a network of computers, distributing and processing large data, for parallel computation.

The Apache Hadoop has two main parts, the Hadoop distributed file system and the MapReduce model. The Hadoop distributed file system divides large chunks of data into clusters and pass them to the MapReduce model, where they are separated to similar data types.

Answer:

Infrastructure.

Explanation:

In Computer science, Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives. It offers individuals and businesses a fast, effective and efficient way of providing services.

Simply stated, Cloud computing are services or programs located on the Internet, they are usually remote resources making use of cloud storage.

When first defining the cloud, National Institute of Standards and Technology (NIST) gave three (3) service models, which can be viewed as nested service alternatives;

1. Software as a Service (SaaS).

2. Platform as a Service (PaaS)

3. Infrastructure as a Service (IaaS).

According to NIST, the five (5) characteristics of a cloud computing service are;

1. On-demand self-service .

2. Broad network access .

3. Resource pooling .

4. Rapid elasticity .

5. Measured service.

Additionally, the cloud service can either be deployed as private, public, hybrid or community service.

Host A sends real time voice to Host B over a packet switched network. Host A first converts the analogue voice signal to a digi

DiKsa [7]

Answer:

Time required is 0.007 s

Explanation:

As per the question:

Analog signal to digital bit stream conversion by Host A =64 kbps

Byte packets obtained by Host A = 56 bytes

Rate of transmission = 2 Mbps

Propagation delay = 10 ms = 0.01 s

Now,

Considering the packets' first bit, as its transmission is only after the generation of all the bits in the packet.

Time taken to generate and convert all the bits into digital signal is given by;

t = $\frac{Total\ No.\ of\ packets}{A/D\ bit\ stream\ conversion}$

t = $\frac{56\times 8}{64\times 10^{3}}$ (Since, 1 byte = 8 bits)

t = 7 ms = 0.007 s

Time Required for transmission of the packet, t':

$t' = \frac{Total\ No.\ of\ packets}{Transmission\ rate}$

$t' = \frac{56\times 8}{2\times 10^{6}} = 2.24\times 10^{- 4} s$

What is the meaning of google?

UkoKoshka [18]

According to the Google guys, the company's name comes from the word 'googol' which is actually a number invented by Milton Sirotta. Probably the Google name is related to the number of the results provided by the search technology which is usually huge.

"The name 'Google' is a play on the word 'googol,' coined by Milton Sirotta, nephew of American mathematician Edward Kasner. A 'googol' refers to the number represented by a 1 followed by 100 zeros. It's a very large number. In fact, there isn't a googol of anything in the universe
