Answer:

Data redundancy.

Explanation:

A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.

A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.

In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.

Data redundancy is the name of situation where the same data is stored unnecessarily at different places.

Simply stated, data redundancy can be defined as a condition which typically involves storing the same data in multiple storage locations. Thus, data redundancy connotes the unnecessary repetition of the same piece of data (informations) either deliberately or for some specific reasons.

Variablesallow us to manipulate data through the ___________.

gladu [14]

Answer:

Reference

Explanation:

Variables provide reference to the stored data value.

For example:

int i = 0;

Here i is a variable of type int with an initial value of 0. i is a reference to this stored value 0. Now if I want to update the data, I can do so using this reference.

i = 1;

Now the reference is used to manipulate the stored data and change it to 1. In a similar manner all updates to the value can be done using the variable reference.

What the repeal of online privacy protections means for you?

kvv77 [185]

Online Privacy is well, our privacy while on the internet. If they have repealed that, then we have no privacy while on the internet. I feel like now a days there is no privacy at all anywhere. Everywhere you go, there are cameras watching you. So for them to take away online privacy is pretty messed up.

Which answer choice correctly distinguishes among the three pieces of data?

wolverine [178]

Answer:

a. 1 is a packet, 2 is data, 3 is a frame.

Explanation:

And what is not mentioned is segment which used TCP/UDP and is part of Transport layer. The packet carries the destination and sender IP address, and is part of the Network Layer. The frame has the Mac address of destination device and senders device and is part of data link layer.

Hence segment has no IP address, hence b. is not correct. Also, data cannot have the IP Address, and Frame has the MAC address, Hence, the above answer. And this arrangement is part of Data Encapsulation.

Also keep in mind data can be anything like a series of bits, or any and it can or not have a header.
