Employee names are stored using a maximum of 50 characters. This information is an example of which of the following?Meta-data

Record instance

Data model

Data retrieval

Answers

Answer 1
Answer:

Answer: Data model

Explanation: Data model is the arrangement of the information in the form of table structure to maintain it in the form of database.They help in the keeping the entities in the sequence and can be tracked when required.Example- vendors records,customer record etc.

Other options are incorrect because the data retrieval is the regaining of the data from database, record instance is the parts of the database records  and meta data give knowledge about other data.

Explanation:

Use the STL class vector to write a C function that returns true if there are two elements of the vector for which their product is odd, and returns false otherwise. Provide a formula on the number of scalar multiplications in terms of n, the size of the vector, to solve the problem in the best and worst cases. Describe the situations of getting the best and worst cases, give the samples of the input at each case and check if your formula works. What is the classification of the algorithm in the best and worst cases in terms of the Big-O notation

Answers

Answer:

Code is provided in the attachment form

Explanation:

Vector Multiplication code:

Vector_multiplication.c file contains C code.

See attachment no 1 attached below

Classification of Algorithm: For creating elements in vector c of size n, number of scalar  multiplications is equal to n. The size of original two vectors scales directly with the number of  operations. Hence, it is classified as O(n).

Cloud storage refers to the storage of data on ______.a. your mobile device.b. your desktop computer.c. an external drive.d. a server on the Interne.

Answers

The correct answer is:

Cloud storage refers to the storage of data on a server on the internet.

Every organization relies on data, In our daily job, we all make use of a huge amount of data(either in gigabytes or terabytes). And if you have a lot of files on your computer, it's probable that your computer may lose momentum and slow down, resulting in bad performance. While there are several external storage options available for storing and backing up your data, these devices are not infallible. Any incident, such as theft, or damage, might result in the loss of vital data.

This is where Cloud Storage comes into play. Cloud storage is a handy and dependable method of storing and retrieving information on the internet.

It is a cloud computing system in which data is stored on the server-side of the Internet and is managed and operated by a cloud computing provider. 

Therefore, from the above explanation, we can conclude that the correct Option is D

Which tool, Wireshark or NetWitness, provides information about the wireless antenna strength during a captured transmission?

Answers

Answer:

Wireshark.

Explanation:

Wireshark is a free and open source network packet sniffing tool, used for analysing, troubleshooting, software and communication protocol development etc.

It uses various extensions to capture wireless and cabled connections like AirPcap (air packet capture), pcapng ( packet capture next generation.

It uses the device's antenna to capture wireless communication and gives the signal strength, noise ratio and other information of the antenna.

Assume hosts A and B are each connected to a switch Svia 100-Mbps links. The propagation delay on each link is 25μs. The switch Sis a store-and-forward device and it requires a delay of 35μs to process a packet after is has received the last bit in the packet. Calculate the total time required to transmit 40,000 bits from Ato B in the following scenarios. (The total time is measured from the start of the transmission of the first bit at A, until the last bit is received at B. We always assume that links are bi-directional with the same transmission rate and propagation delay in each direction unless specifically instructed otherwise.)

Answers

Answer:

885 μs

Explanation:

Given that:

Switch via = 100 Mbps links

The propagation delay for each link = 25μs.

Retransmitting a received packet = 35μs

To determine:

The total time required to transmit 40,000 bits from A to B.

Considering the fact as a single packet:

Transmit Delay / link = size/bandwith

= 4×10⁴ bits / 100 × 10⁶ bits/sec

= 400 μs

The total transmission time = ( 2 × 400 + 2 × 25 + 35) μs

= (800 + 50 + 35) μs

= 885 μs
