What is machine dependent phase in compiler?
1. Target code generation
2. Machine Specific code improvement
What is file manager in Linux?
There is no set file manager in linux. Examples of Linux file managers include but:
Nautilus (GNOME)
Thunar (XFCE)
Dolphin (KDE)
What is the difference between software and data?
Software is an application in your system or OS. A data is files. However, an application is also saved in a data. That's why there is a setup root folder.
What is serial processing in an operating system?
Serial processing in operating system is one of the types of data processing in the computer. The data is read by the CPU, analyzed, processed and then executed in this system.
State the purpose of testing hardware prior to installing an Operating System?
becase if you start installing an o.s you may counter problems if the hardware is faulty as well as it may fail in the future when your just about to save your work or it could happen anytime.
Define operation system.write about types of operation?
The operation system is an integrated set of programs that control,supervises and supports a computer system.Operation system make the computer easier to use,because the machine and its operator.this entire collection of system software programs is known as an operating system. The types of operating system is 1)Processor scheduling 2)Memory management 3)I/O management 4)File management
Difference between operating system and unix?
Actually, UNIX is an operating system. It is generally used in business applications on large mainframe computers. However, many hobbyists prefer it for its simplicity and scalability.
What will happen if a computer does not have operating system?
A computer without an operating system will not operate.
What is the best Linux distro for a new Linux user?
Kernel, but I guess when you will learn, you will have to switch (Ubuntu for programmers and gamers and Kali Linux for penetration testers and hackers)
a. Batch - To batch similar jobs together so that they can run at the
same time.
b. Interactive - reduce response time so that users get a quick response
while interacting with the system.
c. Time Sharing - the CPU will execute multiple jobs by switching
among them, but the switches occur so frequently that the users
can interact with each program while its running.
d. Real Time - used when rigid time requirements are placed on the
operation of a processor or the flow of data.
e. Network - this is simply a communication path between two or more
systems. Sharing file systems or other resources across the net.
f. Parallel - this system gathers multiple CPUs together to perform
computational work. This is just a way of saying multiprocessor
system.
g. Distributed - allow users to share resources across geographically
dispersed locations via a network.
h. Clustered - two or more individual systems that are coupled together
that make a resource or service redundant or highly-available. This
type of system also gathers multiple CPUs together to perform
computational work.
i. Handheld - these devices are usually palms or cell-phones and have
restraints on CPU speed and power consumption.
The last characters after the period in a file name?
Are called a file extension. They typically describe the function of the file. .exe stands for an executable file, a .jpg is an image compression, .doc is a Microsoft Word document, etc.
Translate the operational need into a system performance specification
singletasking is OS which will opperate for single operations,Multi-tasking is a property of an Operating System, not hardware. As implied by the other answers, multi-tasking is the ability to actively manage execution of more than one process or thread simultaneously. That is, the Operating System itself can schedule and manage multiple thread or processes running simultaneously.
a graphic representation of process performance data tracked overtime.and it is also the best continuous data.
System software (OS), it loads at boot up. Examples are Windows 98, XP, NT, 2000, etc.. http://www.webopedia.com/TERM/O/operating_system.html
Different manufacturers of operating systems?
Microsoft Corporation - Windows, MS-DOS
Apple, Inc - Mac OS X
Red Hat - Red Hat Enterprise Linux (commercial Linux distro)
Novell - Netware, SUSE Enterprise Linux (commercial Linux distro)
Sun Microsystems - Solaris
Wind River Systems - VxWorks
QNX Software Systems - QNX
Amiga, Inc - AmigaOS 4
Advantages of virtual machine architecture for a user?
The main advantages are that multiple OS can co-exist on the same computer in strong isolation from each other and tha it can provide an istruction set archtecture(ISA) different from that of the real machine.The main advantages are that multiple OS can co-exist on the same computer in strong isolation from each other and tha it can provide an istruction set archtecture(ISA) different from that of the real machine.
What is solution of external fragmentation?
External fragmentation is solved by any three methods:-
1.compaction:- attacks the problem of external fragmentation by moving all the allocated memory blocks into single unit by combining all free memory holes.
2.garbage collection:- it collects all the memory which is inaccessible and return them as a free memory.
3.paging:-breaking up physical memory into fixed size blocks and than filling these blocks by logical memory of same size.

How much does it cost to put in a new septic system?
This would depend on the size of the septic tank, your land layout and the distance from your property to the tank. Needless to say, installing a septic tank of any kind is quite costly.
What requirements is memory management intended to satisfy?
•Relocation
•Protection
•Sharing
•Logical organisation
•Physical organisation
