The sac character encoding method was addressed to simplify the symbolism of letter and symbols.As the computers grew in capacity UTF-8 method was implemented to optimize such protocol allowing more characters to be included with an expanded string of possibilities

Describe how a user would interact with a smart-phone to do various tasks.Consider inputs and outputs.
xz_007 [3.2K]

A smart-phone is also referred to as a mobile device and it can be defined as a small, portable, programmable-electronic device that is designed and developed for sending (transmission) and receiving data (messages) over a network. Thus, a smart-phone must be designed as a hand-held device with communication capabilities.

Basically, the components that make up a smart-phone can be classified into two (2) main categories and these include:

1. <u>Input:</u> it comprises mouthpiece, keyboard, light sensor, etc.

2. <u>Output:</u> it comprises screen, speaker, earpiece, etc.

In this context, an end user would interact with a smart-phone in the following ways to perform (do) various tasks:

  • By using a keyboard to type a text and then sending it to another person.
  • By using a mouthpiece as an input for voice (audio) messages when making call.
  • The screen of a smart-phone displays the necessary information to an end user.
  • When playing a digital music file the speaker produces the output as sound.

gayaneshka [121]

Answer:

D. Network vulnerability database

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.

In this scenario, The director of security at an organization has begun reviewing vulnerability scanner results and notices a wide range of vulnerabilities scattered across the company. Most systems appear to have OS patches applied on a consistent basis but there is a large variety of best practices that do not appear to be in place. Thus, to ensure all systems are adhering to common security standards a Network vulnerability database, which typically comprises of security-related software errors, names of software, misconfigurations, impact metrics, and security checklist references should be used.

Basically, the Network vulnerability database collects, maintain and share information about various security-related vulnerabilities on computer systems and software programs.

Which of the following statements represents the number of columns in a regular two-dimensional array named values?
puteri [66]

Answer:

(a) values[0].length

Explanation:

In programming languages such as Java, an array is a collection of data of the same type. For example, a and b below are an example of an array.

a = {5, 6, 7, 9}

b = {{2,3,4}, {3,5,4}, {6,8,5}, {1,4,6}}

But while a is a one-dimensional array, b is a regular two-dimensional array. A two-dimensional array is typically an array of one-dimensional arrays.

Now, a few thing to note about a two-dimensional array:

(i) The number of rows in a 2-dimensional array is given by;

<em>arrayname.length</em>

For example, to get the number of rows in array b above, we simply write;

<em>b.length </em>which will give 4

(ii) The number of columns in a 2-dimensional array is given by;

<em>arrayname[0].length</em>

This is with an assumption that all rows have same number of columns.

To get the number of columns in array b above, we simply write;

<em>b[0].length </em>which will give 3

Therefore, for a regular two-dimensional array named values, the number of columns is represented by: values[0].length
