What else can I help you with?
Who did Dennis Ritchie work with?
He created the Unix operating system with Ken Thompson
Who is Unix work performed by?
Unix work is performed by users of the unix system, for application and system programs, or anything that requires a Unix system.
What is Linux?
Linux and UNIX both are operating systems written in C and Assembly languages. UNIX is a primary operating system introduced in the year 1970 by Ken Thompson and others, while it is a multitasking and multiuser operating system. UNIX being a proprietary networking OS, its cost is high for a mainframe system. The end-users of UNIX are not authorised to change the kernel in any way as it results in the violation of the licence in the terms. Later in the year 1991, a Finnish student named Linus Torvalds introduced the initial Linux kernel, which meant a clone of the UNIX. Linux is an open-source operating system and free for anyone to use and modify the code. Nowadays Linux OS is widely used in day to day life like Supercomputers, desktops, smartphones, web server, home appliances, washing machines, refrigerators, cars, modems etc. Operating system: Each time when we turn on your computer, we can see and perform different activities on the system like write, read, browse the internet and watching a video. Well, all these activities are performed by an operating system or kernel. A kernel is a program which is the heart of any operating system, used to communicate between hardware and software. So, to work on the computer we need an operating system. Nowadays Linux is in great demand and popularly used in everywhere. Linux is an open-source operating system which is freely downloaded and distributed over the internet. With time, Linux became an important backbone for an operating system like Knoppix, Debian, Ubuntu, and Fedora etc. source: ITEducationalExperts
For bank system which opertating system is best?
As we have to go with high security and no wastage of time at employees work place it is better and best to opt UNIX or its flavors as the operating system
In what year did work begin on the UNIX system?
1969
What was unix originally written for?
Unix was originally developed because there was surplus electronic equipment around Bell Labs, and some of the researchers who used the Multics system for research and publishing purposes could not get their work done. Unix was originally developed to help with publishing research and reports in a multi-user system to be used along side the Multics multi-user operating system.
Difference between booting and mounting process of UNIX?
The 'boot' process of an Operating System brings it up from a cold or warm sequence, such as power on, or a software initiated reset. It has to bring in the software into memory and get all of the processes running. Once it is down with the 'boot' the system is ready for users to do work. 'Mounting' in Unix refers to mounting a filesystem, i.e. bringing it online for use. The system obviously has to be up and running for this to occur, so a boot process has to complete before you can mount a file system.
What is diffrance between Linux and unix?
Shell is a program which allows the user to access the computer system. Shell is an interface between the user and computer system. Kernel is the only way through which the programs (all programs including shell) can access the hardware. Its a layer between the appliation programs and hardware. It is the core of most of the operating systems and manages everything including the communication between the hardware and software. KERNEL is the core part of operating system. It contain modules like device modules and other modules etc. Kernel is written in C language. Basically kernel is mediator between hardware and Operating System. But SHELL is an interface between users and operating system. Both are mediator but work is totally different. Let we have an example of "eject" command in Linux operating system: User give a command to Shell through input device like keyboard and see that command on video Device like monitor, but in actual concept is user give a command to shell, then this shell transfer that command to kernel.when kernel have module of that command then it transfer to hardware like CDROM. After that hardware behave as the module in kernel and then kernel again transfer the output to Shell. And finally shell transfer that output to user. Hardware <---> Kernel <---> Shell <---> User
What is the difference between C and Linux?
There is very little difference in the C compiler between Unix and Linux; in some cases (the gcc compiler) it is the same. The differences come in when using system calls; some system calls do not exist in Unix or Linux, although most do. The program I work on compiles the same way (for the most part) between all commercial versions of Unix and several variants of Linux. In other words, the code is fairly portable across platforms.
What is Unix used for?
Unix is a computer operating system. It tells the computer how to work. Your computer is actually quite stupid. It knows how to do one thing. When it starts up, it knows how to do one of two things, they are either start spinning the hard disk, or move the memory from location a into the processor. Then the operating system starts telling the computer what to do. It might tell it to take orders from the screen, to add and subtract, to print, to use the internet and how to use the internet, or to do something else.
Does PS3 support external Blu-ray drives?
No. The PS3 operating system loads a specific driver at boot for the internal Blu-Ray drive. With a driver, the external drive will not work. because it is a simple Unix based operating system, there is no plug-n-play capability designed in the programming for an external Blu-Ray drive.
Will flatout 2 for windows work for mac?
Games written for the Windows operating system require the Windows operating system to work. If the Mac has Windows installed on it then it will work otherwise it will not work.
