Statue poster
I open the .xcf image and edit this with Gimp: change the color, the size,the brightness, put a title, cut out a part of the photo and paste in other place, etc...
And finally, when I have edited him, I keep it as "statue-poster" and export the edited .xcf file in .jpg. And make it a post in blog.

Computer Network
WHAT IS A COMPUTER NETWORK?
A computer network is a set of connected computers. Computers on a network are called nodes. The connection between computers can be done via cabling, most commonly the Ethernet cable, or wirelessly through radio waves. Connected computers can share resources, like access to the Internet, printers, file servers, and others. A network is a multipurpose connection, which allows a single computer to do more.
WHAT IS A LOCAL AREA NETWORK (LAN)?
A local area network (LAN) is a group of computers and associated devices that share a common communications line or wireless link to a server. Typically, a LAN encompasses computers and peripherals connected to a server within a distinct geographic area such as an office or a commercial establishment. Computers and other mobile devices use a LAN connection to share resources such as a printer or network storage.
WHAT IS A IP NUMBER?
The Internet Protocol Address (or IP Address) is a unique address that computing devices such as personal computers, tablets, and smartphones use to identify itself and communicate with other devices in the IP network. Any device connected to the IP network must have a unique IP address within the network. An IP address is analogous to a street address or telephone number in that it is used to uniquely identify an entity.
HOW TO FIND YOUR COMPUTER IP NUMBER?
The IP is in the computer terminal. You have to put "ifconfig" and press enter.

Operating Systems 4/4: File System
The File System
What it is?
In a computer, a file system (sometimes written filesystem) is the way in which files are named and where they are placed logically for storage and retrieval.
The File System in each Operating System
DOS, Windows, OS/2, Macintosh and Unix-based operating systems (OSes) all have file systems in which files are placed somewhere in a hierarchical tree structure.
File pathes
In most operating systems and file systems, a route can be expressed in relative or absolute form.
In most operating systems and file systems, a route can be expressed in relative or absolute form.
- An absolute or full path points to the same location in a file system, regardless of the current working directory. To do that, it must include the root directory.
- By contrast, a relative path starts from some given working directory, avoiding the need to provide the full absolute path. A filename can be considered as a relative path based at the current working directory. If the working directory is not the file's parent directory, a file not found error will result if the file is addressed by its name.
