CHAPTER 4 ACTIVITY
In your opinion, which is better: traditionally installed MS Office or MS Office 365. Give their
advantages and disadvantages and the reason why you chose your answer.
I personally think that MS Office 365 is better than Microsoft Office because it gives you up-todate or latest versions and security updates from Microsoft Office. It also offers many plans for different
uses. If you are a student, you can subscribe to the plans for home and personal use with apps like Word,
PowerPoint, and Excel. Another advantage if you avail the Microsoft 365 Family Plan, you can share the
subscription to up to six people in your family and log it in to multiple devices like PCs, Macs, tablets,
and phones. This plan also lets you store files in the cloud (get 1TB of OneDrive cloud per user) and
access them anywhere. Microsoft Office 365 also fits small and large businesses that need remote work
and collaboration tools as it can offer other apps like Teams, Exchange, OneDrive, and SharePoint.
Microsoft 365 also includes free technical support for technical issues or for billing support. The only
downside about Microsoft 365 is you have to pay for the plan monthly or yearly, but I think it’s worth the
price since there are really many features that it gives unlike in MS Office. On the other hand, although
MS Office is a one-time purchase, I don’t really see it as an advantage because you cannot upgrade to the
latest versions. If you want an upgrade, you need to pay or buy it at another full price. Additionally,
unlike MS Office 365, it can only be installed once on either a PC or Mac. There is also no extra storage
included and the technical support is only available upon the installing only.
