Lion-beach, step by step

WHAT I'VE DONE

↪First, I changed the name of the photo to lleó-platja-Aitana Palau.xcf.
↪I cut the lion with the tool: scissors select tool. Then I copied and pasted the selection in a new layer, named lleó.
↪I changed the size of the lion with the scale layer.
↪I adjusted the color of the lion with the tool colors, brightness and contrast.
↪I blur the outline to look like more real with the smudge tool and dodge/ burn tool.
↪I duplicated the layer to create more lions and changed the size and the name of the layers.
↪I aplied some effects to the image: filters, lights and shadows, supernova.

↪Insert my name and the date with a new layer.
↪Finally I saved my work.

↠Then I changed the brightness and the contrast of the image.

↠I created a layer named Title, and I put the text.

↠To do the circle with the hand, I created a new layer and select a circle around the 
figure's hand. I copied and pasted.

↠Finally,I added some filters.

Computer Networks

COMPUTER NETWORKS:  

It's a set of computers and connected electronic devices whose purpose is to share resources. In this concept, they encompass both computer equipment as well as the means of interconnection and the programs or protocols that allow this connection and that different devices can understand the information. 

LAN: 

Local area network or LAN (local area network) is a network for the interconnection of several computers and perifé - rich that limits itself to a relatively small area such as a quarter, an alone building, a ship, or a plane.

IP NUMBER:  

An Internet Protocol address (IP address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two principal functions: host or network interface identification and location addressing.

HOW TO FIND YOUR COMPUTER IP:

→How To Find My IP Address On A Mac:

HFor Mac users, the question of how to find My IP address can be answered by opening up your Terminal program, and typing ''ifconfig'' at the prompt. (Terminal is a program that comes free and installed by default on every Macintosh, and is located in Applications, under the Utilities folder.)  

→How To Find My IP Address On A PC:

For Windows users, here is how I can find my IP address. First, click the Start Menu, and select Run. Next, type ''cmd'' into the box and click the ''OK'' button. Finally, at the prompt, type ''ipconfig'' and information about your IP Address will be displayed. 

→How To Find My IP Address On Linux:

Next, how do I find my IP adress on a machine running Linux? On a Linux system, I can find my IP address by typing ''ifconfig'' at the prompt, which will output information about my IP Address.  




HOW TO FIND YOUR COMPUTER IP NUMBER

• You'll need to open a Terminal.
• It's located  at the bottom of your screen.  
• Click Applications >Acessories > Terminal 
• When terminal is open, type the following command: route 
• We execute the command ifconfig. 
• A window will appear as that of the example wherefrom we can extract the following information:

THE FILE SYSTEM

What is it?

In computing a file system or filesystem is used to control how data is stored and retrieved. Without a file system, information placed in a storage medium would be one large body of data with no way to tell where one piece of information stops and the next begins. By separating the data into pieces and giving each piece a name, the information is easily isolated and identified.

The File System in each Operating System

Windows file system:

Microsoft Windows operating system uses two main file systems: 

FAT, inherited from the old DOS with its later extension FAT32, and widely used NTFS file systems. Recently launched ReFS file system was developed by Microsoft as a new generation of file system for Windows 8 Servers. 

 

FAT (File Allocation Table)

 

It is one of the simplest types of file systems. It consists of a file system of the descriptor sector (boot sector), a file system table of block allocation and the storage space without format to store files and folders. FAT files are stored in 32-byte record set directories. Record of file attributes of the first block of a file. Any next block can be found through a block allocation table, using it as a linked list.

File pathes

A path, the general form of the name of a file or directory, specifies a unique location in a file system. A path points to a file system location by following the directory tree hierarchy expressed in a sting of characters  in which path components, separated by a delimiting character, represent each directory. The delimiting character is most commonly the slash, the backslash character ("\"), or colon (":"), though some operating systems may use a different delimiter. Paths are used extensively in computer science to represent the directory/file relationships common in modern operating systems, and are essential in the construction of Uniform Resource Locators. Resources can be represented by either absolute or relative paths.

Operating Systems 3/4: Installation

Step 1: Open terminal, Press Ctrl + Alt +T.
Step 2: Navigate to the directories were you have saved the .deb package on your system. For example, here we have saved in the download folder of home directories.
Step 3: To install any software or making any modification on Linux require admin rights, which is here in Linux is SuperUser 
Step 4: Here, we are installing Foxit Reader software package on the system, which is present in the download folder of home directories. Using “ls” command will list directory content.
