Exercise number 2

When I commented Camila's post I first didn't know what I should comment, except for: " Great!!!", then I read the article about how to think up with good comments and some comments from other classmates and it helped me a lot. So I started writing what I felt while I was reading it, congratulations and why I liked it. I also just wrote the positive things (although nothing was negative).And of course the part of not repeating words was difficult to, especially "I".
I liked commenting a classmate, it is like saying to them in person  if you liked it, what you felt while  you where reading it, etc...    But commenting in a blog is different, more formal (for me), the text is longer,  and its new for me.

Exercise Nr 2 Topic: commenting some posts

 

 PERSONAL REFLECTION

While I commented on Feli´s post, at first, I felt a little lost, because I did not know how to start the comment. But after reading the instructions on how to comment a post, I felt more confident. Then, I read some comments of other classmates and that helped me to realize, what I really had to put in a comment. So that helped me to. After that, I really thought about, how I felt, reading the post and that is what I commented on. I also concentrated on always finding different words, because then, the comment would be a little more interesting. I also focused on relating some things out of the post with my experiences.

What I also did is evaluate Feli´s post. I think that that is very important, so the owner of the post (the author) knows if I the reader liked the post or not. If you do this, it is important to perform it in a nice way, not hurting the author's feelings or insulting him.

                                                         Cloud Computing


Cloud computing is the simple possibility to access  via internet servers, storage, databases and a broad range of applications. The ressources are not on your own Computer, they are distributed in a pool of computerressources and managed by service-providers.
 In most cases we are talking about Public Clouds - for the broad public, but a lot of companies have already there Private Clouds because of confidentiality reasons.
In General exists 3 different types of Clouds:
-Infrastructure Cloud is the most simple form, where only hardware and access to data-management
  is offered. You rent Hardware and maintenance.
-Platform-Cloud, the middle type,  where the user can control self-loaded programs and data,
  using networks, storage and dataprocessingsystems.
-Application-Cloud, the highest form, where the Client uses applications not on his own Computer,
  he rents finished programs in the cloud.




The big advantages are:
no maintenance and administration costs, nearly indefinitely storage capacity and global usage of data and applications.


Risks are:
lack of Internet access, no confidentiality for intelligent hackers (US-government can see it all)


For me personally: I have my Music, my photos, and a lot of my games everywhere available with
all my equipment, smart phone, tablet, laptop or desk top.

Data Storage
The data storage is that what saves all the information from our Pc,phone or tablet. It's one of the most imprtant things of all phones,Pc and tablet. All this information is in one data storage. If there is a problem with the data storage where is all the information of your computer the others data sorages around the world have a emergency copy for these problems. So you don't will have any problem. In the datas storages there are many levels of security.

There are a limit of electronic information a device, a pendrive, or a chip can have. And so like there are milimeter, cm, dm, meter, km,etc... there are bites, kilobytes, megabyte, gigabyte, and others.

1)What is a data storage?

Data storage is a general term for saving data in electromagnetic or other forms used in a computer. There are different types of data storage. In addition to hard data storage, there are now new options for remote data storage, such as the cloud, that can revolutionize the ways that users access data.

Data Storage for Data management

The Data Storage is the set of specifications used to define how, when and what is stored. In any organization, regardless of industry or size, it can be seen that data is growing at an exponential rate and that creates a problem for storing. It is no longer enough to store, but you have to define a strategy that provides the basis of storage. Data Storage function seeks to implement good practices and policies that meet the objectives set from the Data Management, so that no alignment is lost. A graphic example would be to compare the management of food to keep in the pantry of a house with food to store in a supermarket. While in the first case the volume is so manageable that does not require an order in the second, the logical order is essential .

The benefits that adequately cover the requirements of the Data Storage function within the data management would be the following , among others :

Savings: the ability of a server to store data is limited , so save data without structure, without a logical order and lacking guiding principles , is a rise that could be avoided .
Increase productivity : when data is not stored correctly the system works slower . One of the strategies that are commonly used to avoid this is to divide the data into active and inactive . The latter would be stored and compressed in a different place , so that the system remains agile, but without involving that are completely inactive , as once may need to access them again.

Usually there must be a responsible of the Data Storage. It’s the person who defines how, when and what is to be stored.

Exercise Nr 1: 1) Data Storage

The Data Storage feature is the set of specifications used to define how, when and what is stored. In any organization , regardless of industry or size, it can be seen that data is growing at an exponential rate and that creates a problem when storing. It is no longer enough to store, but you have to define a strategy that provides the basis of storage. Better explained, Data Storage is a capacity of store. The Data Storage can’t be virtual because it’s more safe physically. Data Storage contains all the information that one posts on the Cloud. If one loses information, this one resolves it by giving it back. Data Storage function seeks to implement good practices and policies that meet the objectives set from the Data Governance , so that no alignment is lost. A graphic example would be to compare the management of food to keep in the pantry of a house with food to store in a supermarket. While in the first case the volume is so manageable that does not require an order in the second , the logical order is essential.

The IBM 350 was the first disc drive introduced by IBM. It had a Data Storage capacity of about 3.75 MB and was available on lease $3200 per month.

Examples: discs, CD, RAM, DVDs, Storage Tapes, Memory carts, Floppy disks, etc…

What is meant by data storage? By Lisette Habig and Astrid Corbacho

Data storage

“Data storage” is a name for storing a data on the computer.You can store any kind of information. (That could be music, videos, audios, documents, pictures, emails...) This information is considered memory and the components that store it are termed primary storage.

• Primary storage: The place where you can store memory on the computer. This data is is stored inside the computer. Most of the time the primary storage is the RAM. The word RAM means nothing else than RANDOM ACCESS MEMORY and it is a type of Computer memory. It is also the most typical type of memory used on computers, and other devices. There are two types of RAM:

• -DRAM: DYNAMIC RANDOM ACCESS MEMORY

• -SRAM: STATIC RANDOM ACCESS MEMORY

       These two types of RAM differ in the technology they use to hold

        data. DRAM is the more common type. SRAM is faster.

• Secondary storage: Here you can store the memory on a hard disc in devices like: CD-ROOM DISK, USB, Flash memory sticks,...This memory is stored in devices outside the computer and you can insert them and pull them out.

Exercise Nr.1 1.

1.
Data storage means saving all your electronic information like photos, documents and videos. Everything a computer knows is called storage data. A data storage device is an object that records that information in an electromagnetic way. 

There´s three types of storage devices: 

The primary type: Primary storage is the storage that is directly connected to the computer. It´s volatile information, meaning that it can only save your data while the computer is on. Random Access Memory and cache are primary storage devices. 

The secondary type: These storage devices aren´t volatile, so they will keep existing while the computer isn´t running. They´re cheaper than primary storage devices. Secondary storage devices can be internal, external or removable. Examples: hard drives, DVD´s, CD´s.

The tertiary/offline type: Offline storage isn´t used as much as the other two storage types are. They have to be inserted into the computer to edit or access any data saved on them. The data saved in these devices stays in the device even if its disconnected from the computer. Examples: compact disks, floppy disks, USB´s.

DATA STORAGE

You can save your information in many ways. You can write the down on a paper, you can save them on a photo album , on a camera, etc.But today, in this generation  you can also save them on a computer, pen drive ,cd, chip, etc. These last four are called data storage devices. But what is a data storage? A data storage is the electronic way of saving your data. An information ( data) deposit (storage).In the computer, iphone, ipod. Pen drives and CD’s were used to transfer information to other devices, but today , you only need a device connected to internet to access to the cloud. You can take your photos , videos and music everywhere .When you saved some photos in your pen drive, you connect it to the computer and the photos show up. CD’s are more used to save videos and then show them on the tv, but , the cloud is the modernist form of saving data . The cloud allows us to save photos, texts, videos and also  share them with friend. The most used of the CD´s, pen drive, and the cloud is the cloud.
