Unix

Yes. Some versions of Unix are capable of running on the same hardware as Windows. Mac OS X, a certified version of UNIX, includes a utility known as "Boot camp" to install Windows in a dual-boot setup easily. Solaris 10 can also be used in a dual-boot setup by carefully partitioning the drive and setting up GRUB.

Use the 'uname -a' command. It reports on the Unix system, version, machine name, amongst other things.

Definitely not. Unix was developed around 1969 - 1972, and Operating Systems have been available since the very late 1940's, early 50's.

ls-lS | tail-1

White flour is made only with the endosperm portion of the wheat kernel. Farina is also made from the endosperm, but it is ground to produce a granular product.

a=10;

b=20;

c=`expr $a + $b`;

printf "$c";

I don't believe there is a PS system call; however, there is a 'ps' command that is commonly used to show all (or a select few) processes running on the system and their resource utilization.

It is also used so that users can terminate disconnected processes when they don't want them to run anymore.

Line Movement.

We are not sure what you mean by "shearing", it is men that "shear" sheep in timed competitions, not operating systems.

It is never a good idea to log in to the system as root, unless it must fixed in administrative mode. The disadvantage is that you have to be very careful because you are operating at the root account level, which lets you do anything you want without checking for safety.

The only advantage is that you are running under a privileged program and can anything you want on the system.

Windows uses a character sequence to indicate the of a line, which is usually a carriage return - line feed sequence. This is two characters for the end of every line. You might see a sequence of x'0D0A' characters to end a line in Windows.

UNIX uses the concept of a 'newline', which is a single character (usually a X'0A' character) to indicate the end of a line.

It generally refers to setting the text that will appear when the shell prompt is asking the user to type in a command, meaning, the shell needs work to do. The standard prompt in most shell environments is a single character, such as '#', '$', or '%'. By setting the prompt you can customize what appears when the system is idle and wants you to type in a command to do something.

Bell Labs, was the person who created UNIX.

Shared web hosting is what most people mean when they refer to "web hosting". It simply meas that many customer's websites reside on a single web server, and that the server's resources (CPU and RAM) are shared among every customer account on the machine.

The boot block of any OS contains the initial loading sequence of the Operating System. It starts the process of bringing into memory the first part of the Operating System which in turn brings the rest of it in for the entire boot process.

This is known as bootstrapping the Operating System.

Use the command:

ps -u jtaylor

gedit is a visual editor that can only be used in a graphical desktop environment. 'vi' is a standard and can be used in a terminal window without resorting to a desktop environment.

A source file is typically a readable, Ascii file, that is not the result of a compiler or translator to binary machine code.

Avogadro's number is a constant. Therefore only one number is equal to Avogadro's number.

It lists the contents of several ipc queues, including semaphores, shared memory segments, etc. It can also remove items from these queues.

A zombie process is a process that completed execution but still in process table. When a process ends, all of the memory and resources associated with it are deallocated so they can be used by other processes. However, the process's entry in the process table remains. The parent can read the child's exit status by executing the wait system call, at which stage the zombie is removed After the zombie is removed, its process ID and entry in the process table can then be reused. However, if a parent fails to call wait, the zombie will be left in the process table. In some situations this may be desirable, for example if the parent creates another child process it ensures that it will not be allocated the same process ID.

The most reasonable answer to this question can be applied to all systems; any port that is not being used should be closed. Any open ports that have listening programs should be audited for vulnerabilities.

The a default Unix shell is the shell that comes with and is activated initially with your distribution of Unix. The shell is essentially the program the runs the command line interface allowing someone to interact with their computer. Some examples are the Bourne-Again shell (bash) or the Bourne shell (sh).

Unix work is performed by users of the unix system, for application and system programs, or anything that requires a Unix system.
