Description

Go that is called a ‘C for the 21st century’ was designed in 2007 to address some of the industry problems.

Today, many well-known companies like Google, Adobe, Facebook, IBM, and many more use Go.

They use Go, because of its simple approach to implement complex concepts.

This practical course will enable you to build simple, reliable, and efficient software, delivering basic to advanced concepts using Go.

The course is over 23 hours, including 160+ lectures, over 163 code examples, chapter assignments and a final assignment.

Emphasis has been placed on reviewing code examples, diagrams and white boarding.

The course gradually moves from basic to advanced topics and eventually ends with a final assignment.

In 16 sections, it covers topics such as language fundamentals, control structures, arrays, slices, maps, functions, callbacks, closures, pointers, structs, interfaces, concurrency & parallelism, goroutines, channels, packages, documentation, error handling, unit testing, json, files, reflections, MySQL, and may more.

Who is the target audience?

  • Programmers willing to learn core Golang programming (covering basic to advanced topics)

[ad_1]

Answer:

data encryption and virus scanning utilities

Explanation:

In this scenario, Jack has determined that a virus has infiltrated his computer and corrupted several data files, but he doesn’t know what to do.

The two most helpful utilities are data encryption and virus scanning.

If Jack encrypted his data files and use virus scanning to scan the computer for viruses, the computer’s firewall will quarantine and delete the virus.

So, the correct answer is data encryption and virus scanning.

Hey there!

Let’s assume that this question is referring to every digital calendar ever made. As in, even those made on devices without internet connectivity or any other fancy features that we utilize with many digital calendars today. 

If a planning device that came with a digital calendar didn’t have internet connectivity, it wouldn’t be able to be connected to the cloud. Back when these devices were around, it wasn’t even plausible to store things like calendar events and contacts in what we know as the “cloud”. Also, these devices probably had to be hardwired to a computer and new software had to be downloaded to them, so the updates weren’t automatic. Archaic, right?

Also, consider the fact that even reputable websites/companies such as Google with Google Calendars or Apple with iCalendar will never go without their malfunctions or threats. Sometimes, these websites can be hacked and the data that they contain can be compromised, especially if they’re stored on the cloud. Also, even though it’s not realistic, Google or Apple could one day decide to completely get rid of their calendar programs altogether. So, this means that digital calendars are definitely able to be destroyed or lost. 

That just leaves “They can be used anywhere”. This is true, even with those archaic devices specifically used for scheduling events and such. Nowadays, you have your phone and possibly a laptop on you at all times, which will likely have a calendar on it as a stock application. So, I think this is your answer. 

Hope this helped you out! 🙂

Answer:

Option C – BD=76 cm

Step-by-step explanation:

Given : You are designing a diamond-shaped kite. you know that AD = 44.8 cm, DC = 72 cm, and AC = 84.8 cm.

To find : How long BD should it be?

Solution :

First we draw a rough diagram.

The given sides were AD = 44.8 cm, DC = 72 cm and AC = 84.8 cm.

According to properties of kite

Two disjoint pairs of consecutive sides are congruent.

So, AD=AB=44.8 cm

DC=BC=72 cm

The diagonals are perpendicular.

So, AC ⊥ BD

Let O be the point where diagonal intersect let let the partition be x and y.

AC= AO+OC

AC=  x+y=84.8 …….[1]

Perpendicular bisect the diagonal BD into equal parts let it be z.

BD=BO+OD

BD=z+z

Applying Pythagorean theorem in ΔAOD

where H=AD=44.8 ,P= AO=x , B=OD=z

H^2=P^2+B^2

(44.8)^2=x^2+z^2  ………[2]

Applying Pythagorean theorem in ΔCOD

where H=DC=72 ,P= OC=y , B=OD=z

H^2=P^2+B^2

(72)^2=y^2+z^2 …………[3]

Subtract [2] and [3]

(72)^2-(44.8)^2=y^2+z^2-x^2-z^2

5184-2007.04=(x+y)(x-y)

3176.96=(84.8)(x-y)

37.464=x-y ……….[4]

Add equation [1] and [4], to get values of x and y

x+y+x-y=84.8+37.464

2x=122.264

x=61.132

Substitute x in [1]

x+y=84.8

61.132+y=84.8

y=23.668

Substitute value of x in equation [2], to get z

(44.8)^2=x^2+z^2

(44.8)^2=(23.668)^2+z^2

2007.04-560.174224=z^2

z=sqrt{1446.865776}

z=38.06

We know, BD=z+z

BD= 38.06+38.06

BD= 76.12

Nearest to whole number BD=76 cm

Therefore, Option c – BD=76 cm is correct.

A. Defragmenter. If your files are scattered all over the disk, loading them takes a long time. This can happen because your disk will utilize all empty spots, even if a file doesn’t fit. A defragmenter moves the pieces around until they form one contiguous file, which loads way faster.

Disk cleanup is only about freeing up space by deleting unused stuff.

Quicktime is a video codec, allowing you to view Apple format videos

Winzip compresses files. This may slightly speed up loading time, but you have to add decompression time to it, so it wouldn’t increase productivity.
