     What is hyperloop? Hyperloop is an ultra-high-speed floor transportation machine for passenger and cargo, proposed as a thought by means of Elon Musk, the CEO of Tesla and SpaceX, a couple of years ago. The hyperloop machine consists of a community of tubes, connecting mobility hubs round the world, with pods travelling at ultra-high speeds in a vacuum. The low-pressure surroundings ensures energy-efficient operation thanks to low aerodynamic drag. Contactless magnetic levitation and propulsion structures allow a relaxed and silent passenger experience. Hyperloop combines the key advantages of pace and flexibility, alleviation and security as nicely as sustainability. Ultra-high speeds :- Contactless levitation and propulsions structures blended with a low stress surroundings enable hyperloop pods to tour successfully at ultra-high speeds. Emission-free transportation :- With fully-electric and energy-efficient operations, the hyperloop device objectives at being climate-neutral o

Use internal and external commands of DOS file operation:- There are two types of commands in Dos. •  Internal command  •  External command Internal commands- This commands, which are automatically loaded into main memory of computer during the booting process. They are actually included in the command. Com file. So these are executable immediately after gating the DOS prompt. CLS-      Syntax-    CLS        Definition-    This command is used to            clear the screen  Example-   D:\ TRAINING>CLS DATE-             Syntax-    DATE [/T|<date>]                      Definition- This command is used            to display or set the system date.            Type DATE without parameters to            display the current date setting                and prompt for a new one. Press             ENTER to keep the same date.               /T - Switch which tells the                            command to just output the                        current date, without promoting           

The file system   The DOS File system  lets us store information in named files.  You can call a file anything you like which might help you remember what it contains as long as you follow certain basic rules. 1.   The names can be up to 8 characters long. You can use letters and digits but only a few punctuation marks (! $ % # ~ @ - () _ {}). You can't exceed 8 characters or use spaces or characters like * or ? or +. Names are case-insensitive, i.e. it doesn't matter whether you use capitals or lowercase letters; “A” and “a” are treated as the same thing.  2. File name can also have an extension  of up to three characters, which describes the type of file. Three are some standard extensions, but you don't have to use them. Examples include COM and EXE for executable programs, TXT for files, BAK for backup copies of the files, or CPP for C++ program files. The extension is separated by a dot from the rest of the filename.  For example, a file called FILENAME.EXT has an 8 ch

Introduction to DOS ➡️ DOS stands for (Disk operating system), and it is a name for the basic IBM PC operating system. DOS is command User/Line interface (CUI) Operating system software. Several varieties of DOS are available , including Microsoft's versions of DOS (MS-DOS) , IBM's version (PC-DOS) , and several others.             There are actually several levels to DOS. At  the lowest level is the BIOS  (Basic input/output system)  which is responsible for managing devices like the keyboard and disk drivers at simplest possible lavel e.g. the BIOS let's you say things like ( get me sector 5 of track 3 from disk drive 1). This is done partly by software in ROM (Read-only memory) and partly by BIOS extension, which are loaded when the system first starts up (with MS-DOS, these are in a file called IO.SYS; on PC-DOS they're in IBMBIO.COM).     The second layer provides a set of higher level services implemented using the low-level BIOS services; you can now refer to dis
