Treatment of IT applications

Treatment of IT applications

What we will see:  

• In this blog we will comment what we have done in the UF1 module 7 of the school ETP xavier, (the pupils of IT treatment of the information of 1 º of management) where we will speak about the IT systems, the work in the network and the search of information.

Usefull tips:

• We are going to put the things that you will know after you read the page, at the end of each page as a list for make more easy found the information.
• We would delight that you leave comments to us to improve the blog, thanks.

Informatic Equipment

Informatic equipment
What is it?

A computer equipment is a machine with the ability to operate a data set.

It consists of two clearly differentiated parts: the Hardware and the Software.

• Hardware items (the physical part of the computer).

- Motherboard: where you connect the rest of components.
- Data Procesor: is the brain of the computer
- Ram: It saves the temporaly data of the computer.
- Hard drive- it stores data
- BIOS: controls the hardware connections and the boot of the system
- Ports : are the cables through which signals circulate between elements of the CPU
- Expansion card: connects the Motherboard to add or improve the functions of the computer.

• Software items: (the logic of the computer)

         Operative system: It is the software that manages all the interactions of the components of an             IT system

• Comunication system (it is an exit that has the IT equipment that allows to exchange information with a device hardware)

• Type of port

1. PS/2 – to connect the keyboard and the mouse
2. USB -for the connections of peripheral on the computer.
3. Firewire -made communications at high speed without it being necessary of a intermediary 
4. Video - it exists a  VGA port for connections of analogical DVI and HDMI video port, and in the case of digital monitors. audio-minijack connectors identified by their colors blue, green and pink (audio input, audio output and microfon 
5. External comunications -Used to connect cables of telephony and devices of communication by means of cables of network, of local areas

What we have lerned:

- The physical par of the sistem "hardware"

- The logic of the computer "software"

Operative System Windows 8.1

Operative System Windows 8.1 


Beginning screen - once started windows 8.1 the first thing that it requests is the user's identification, as soon as the user has been identified goes on the beginning screen " where you can find all the necessary things to realize the most habitual tasks ". It is possible to personalize it.

Bar of access to frequent tasks - its a faster way to realizing the most frequent tasks. It offers five options:
Search - uses Bing's intelligent search to realize searches in the equipment.
Share - where elements can be shared by other contacts, by e-mail across the cloud or across other applications like Ever - Note.
Beginning - to return to the screen of beginning
Devices - where there are selected the devices to which information wants to send.
Configuration - to change the most common options of configuration.
Office - is the place where the programs are executed and where you can find the bar of tasks, there can be created direct accesses to programs, folders or files that are used frequently.
Bar of tasks - is placed in the low part of the office and shows the programs and the apps that they are in execute, also they can anchor to the bar of tasks.


What we have learned:

- The important parts about windows 8.1 and all his utilities

Other operating systems.

Other operating systems.

 Linux 

Linux is a free operating system so that it is possible to use it, to modify it and to redistribute it freely. The distributions are formed by the own operating system plus a general software and a kind of specific programs. The user can choose the distribution that better one adapts to his needs.

Top panel - is a bar placed in the top part of the office and that does the corresponding functions:

 Apps - To view programs organized in categories
Places menu - equival a l'equip de windows. equivalent to the Windows computer
Menu sistema - offers the configuration and managementof the computer

Direct acces -it shows the programs on the top panel
Resident applications - turn off, user's change or blockade of the screen.


What we have learned:
- What is Linux
- How does it work

Components of a network system

Components of a network system 

A network of is a set of equipments interconnected by means of cables or waves.

They consist on: 

•  Servers: computers of the network with high-level hardware and a specific software to centralize and to control the network, give such services as control the Internet access, the safety of the files, current accounts and passwords of the users etc.

• Working stations: they are the IT equipments used by the users of the network.

Conduits: it is the form of communication.

• Devices of connection: hardware that allows to create the network and to distribute the signals.

• Software of the network: program installed with the operating system that allows to form the parameters necessary for the network.

• Peripheral: they communicate with all the working stations, to avoid to duplicate resources.

 Windows in network 

The operating system has the whole software necessary built-in to be able to be employed at network. Depending on the version of windows, the system will be more orientated to the work as a server or as client. Once installed the network physically, it is necessary to form the protocol of communication, most used it is the protocol Tcp / Ip.


What we have learned:

How does a network work.

Finding information

Origins, evolution and the history of the network.

In the link (http://standards.ieee.org/events/ethernet/history.html )speaks about the evolution of the idea of a network of communication of military use that connects strategic world points to the use that we give him nowadays to the opened and free network. 

Searcher:

 A searcher is a program client installed in the user's computer that allows him to go into a remote service, in this case to a source of information, this information is on the servers of the creators of the web pages. 

Google 

Google has a seeker much more faster and easily to use, little by little google searcher has been adding functionalities to the seeker, translator, mail, blogs, documents, news, maps, up to an operating system. Google arranges the results by means of a few own algorithms to estimate the relevancy of every result, being based on the PageRank. This sistem that punctuates the web pages depending on the links found across other pages.

Advertising of Google
Google forms his advertising in order that it is according to the searches realized to be interesting for the user.

Premium Sponsorship

They appear on the pages of results, there are two for every page of results 

AdWords

They appear in the right part of the screen of results, the advertiser manages his own announcements, is like buy words, and whenever someone messes about on them, his advertisement will appear.


What we have learned:

- The history of "arpanet"
- What is a searcher
- Diferent uses of Google

Security

Security

 Like we are used to use the resources on line, it is suitable to have a good safety to attack threats:

-Firewall: it has the mission to stop the assaults of worms and hackers by means of a control of ports software.




- Antivirus: program that detects and eliminates the virus.

 - Antimalware: program that it protects against not wished software.



What we have learned:

- The most important parts of the safety

Our Opinion.

• About these formative unit: 

- In this unit we have learned the bases of the computer science, with this basic knowledge, we will be capable of understanding the following topics easily.

- The way in which we have done the formative unit has been easy enough and bearable, interactive enough.

• What has drown our interest:

The whole world knows that the Internet was used militarily, but the advance of his history its more unknown, I think that it is interesting that his history was revised.
