Operating Systems

An operating System is the most important software running on your computer. It acts as a bridge between the user and machine. It provides an environment for application to run. Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers.

Operating system is interface between computer user and computer hardware.

They use Linux based operating systems. Some say they use highly costumised Ubuntu - Goobuntu.

yes a Symbian is a multi user os unlike open source os as that of androids,but androids do support multi user os.

The 2 main operating systems using on computers are Microsoft Windows and Apple Mac OS.

Windows is available on all PCs and Mac OS is available on any Apple Computer.

In RAM

yes shiraz yes

Yes; without it your computer might as well be a giant paperweight! Without software hardware is useless.

1.high CPU efficiency.

2.each user gets CPU time.

1 Gigabyte = 1024 megabytes 1 Megabyte = 1024 kilobytes 1 kilobyte= 1024 bytes 1 byte= 16 bits

How long it takes after you turn the computer on to be able to use it.

The three main functions of an Operating System are process management, memory management and file management.

The Kernel

Distributed computing is decentralised and parallel computing, using two or more computers communicating over a network to accomplish a common objective or task. The types of hardware, programming languages, operating systems and other resources may vary drastically. It is similar to computer clustering with the main difference being a wide geographic dispersion of the resources. An operating system (OS) is a software program that manages the hardware and software resources of a computer. A key component of system software, the OS performs basic tasks, such as controlling and allocating memory, prioritizing the processing of instructions, controlling input and output devices, facilitating networking, and managing files.

processes are concurrent if they exist at the same time.concurrent process can function completely indepently to one another.

two process are concurrent if their execution can overlap in time; that is, the execution of the secon process starts before the first process completes.

concurrent processes generally interact through the following mechanisms:

Shared variables

Message passing

Electrical basics Get a job with someone knowledgeable, as a helper, for about five years, attend electrical classes at night, read every technical manual you can secure and learn the various electrical codes.

That should provide a rudimentary understanding of what is required.

to monitor traffic or computers on the natwork and to monitor data being sent on the network

1.efficiency

2.Transparency.

3.Consistency

The IDS method that is operating system dependent is Network Based

Yes, although to use multi-programming effectively your hardware needs to have multiple CPUs.

Network Administrator.
