Some details may be different from what is written below, and the answer should be updated accordingly. The best desktop operating system to use depends on what its intended use will be and who will be using it. There is no specific operating system which can be called "the best" overall, and since most current operating systems share most common and advanced features...

What is the most secure operating system?
Security is a difficult and sometimes controversial thing to analyze. The only truly "secure" operating systems are those that have no contact with the outside world. The firmware in your DVD player is a good example. Among all modern general purpose operating systems (Windows, Mac OS X, Linux, Solaris, FreeBSD, NetBSD, OpenBSD) the most secure by defualt is by far OpenBSD. OpenBSD has an extremely stringent security auditing policy; only two remote attack vulnerabilities have been found in the last ten years. This...

What is reentrant kernel?
A reentrant kernel enables processes to give away the CPU while in kernel mode ,not hindering other processes from also entering kernel mode. A typical use is IO wait. The processes wants to read a file..It calls a kernel function for this. Inside the kernel function,the disk controller is asked for the data . Getting the data will take some time & the function is blocked during that time. With an reentrant kernel,the scheduler will assign CPU to another process until an interrupt...
What is the difference between system software and application software?
A system software is any computer software which manages and controls computer hardware so that application software can perform a task. Operating systems, such as Microsoft Windows, Mac OS X or Linux, are prominent examples of system software. System software contrasts with application software, which are programs that enable the end-user to perform specific, productive tasks, such as word processing or image manipulation. System software performs tasks like transferring data from memory to disk, or rendering text onto a display device. Specific kinds of...

What is a command-driven operating system?
Essentially, all computer operating systems (OS) are command driven. A command is digital "to do" list issued to the OS brain (kernel) that commands it to utilize the computer hardware and/or software to accomplish something. In today's operating systems, like Windows 7 or Snow Leopard, you can use your mouse or keyboard to kick off a command in the background. For instance, clicking on "New Folder" in Windows Explorer is a command to create a new folder. Most often though, when people refer...
What is the difference between multitasking multiprogramming and multiprocessing?
I have both BSCS and MSCS, with 24 years in industry, and I have heard the use of these terms vary depending upon who is using them, but this is my view based on my experience. Multiprogramming is an old and arcane term, that was originally used to describe the earlier timesharing type of system where multiple jobs/Programs could be submitted to a computer system, and it should share its various resources between all of the jobs that were running. The jobs/programs...

What are the different types of booting?
They are of two types: Single-Boot is the act of installing only one operating system on a computer and it being able to boot automatically when the computer starts. Multi-Boot is the act of installing multiple operating systems on a computer, and being able to choose which one to boot when the computer starts. In addition, there are several type of booting divided by the source (i.e. location) of the boot code: Non-volatile storage boot - by far the most common, the boot code resides...
What is the difference between distributed operating system and network operating systems?
The network managers are responsible for all the customers, including other networks that they buy and sell electricity to and from. Typically the distributed operating system mostly worries about the local electricity needs, however incompetent behavior is often penalized such as shut down without warning of the distributed system, non-sinusoidal waveform, poor power factor, poor phase matching, over loading interconnecting power lines and high or low voltage operation = the voltage needs to be matched plus or minus about one volt. Neil Or alternatively,...

What is best-fit in operating system?
Best Fit The allocator places a process in the smallest block of unallocated memory in which it will fit. Problems: It requires an expensive search of the entire free list to find the best hole. More importantly, it leads to the creation of lots of little holes that are not big enough to satisfy any requests. This situation is called fragmentation, and is a problem for all memory-management strategies, although it is particularly bad for best-fit. Solution:One way to avoid making little holes is to give the...
