The Elements Of The Operating System For Linux

2. Which of the following is an example of the hardware component of an information system?

When the user begins to interact with the computer, the software being used will send out a system call that will specify a task that a hardware component must perform in order for the software to continue functioning and send further requests,

The Operating System manages the flow of data and tells the processor what component needs to be doing. It does this my relaying one piece of information at a time but done so fast it seems it is doing it all at the same time. It does this by giving the information to the processer in computer language, so it can understand.

RAM: RAM stands for Random Access Memory. It is a bit like a person's short-term memory. RAM is volatile so data only exists only when the computer is turned on, and is used by the operating system and other applications.

i) Memory : cache server (holds recently acesed web pages in its RAM, for spedier aces

Random Access Memory (RAM) - the storage of data and instructions inside the primary storage is temporary. It disappears from the RAM as soon as the power to the computer is

1.19)Ans.The interrupts are used to indicate events like change in events or if any error occurs or freeing of resources or I/o

In workstations associated with servers the assets like memory and processor ought to be managed carefully.

The program by its self is just instructions writing in code where a process is an active program which has been executed. The CPU executes one instruction at a time until the process completes.

server responds to incoming client requests. It should be noted that a server typically starts

Briefly explain the deencapsulation steps in the communication from host B receiving a message from Host A destined for an active application.

Network protocol communications, network connections established by host computer, network routing information, information about computers

Linux is a trademark owned by Linus Torvalds [1]. It is an operating system which is powerful, free and inexpensive to own based on UNIX [1]. It is a POSIX-compliant with versions available to install in cell phones, supercomputers and most computing systems [1]. Linux is an open source program as its source code is available to the general public for use and the right to modify from its original design without any charges [1]. New code will be added to the next version made available with Linux if it is accepted as a universal improvement [1]. The code will continue to exist and developed by the user even if the company fails [1]. Moreover, updates for Linux are available every six months [1]. Nowadays, Linux is in constant development by

In many systems architecture, the kernel is the lowest level of software that interfaces with the hardware in a computer. In UNIX, users typically have no direct access to it. It is responsible for interfacing all applications that run in user mode including the physical hardware and allowing processes to get information from each other.

The same is real for Linux system. There are a large number of customized and typical Linux system programs.
