What is the difference between Unix and Unix-like?
In order to legally be called a "Unix" system, operating systems must undergo a rigorous and expensive certification procedure. "Unix-like" refers to systems that have an architecture similar to Unix, but have not undergone certification.
Where can one learn something about Unix classes?
There are a lot of online based courses for Unix, most of which only take around a week to complete. You can use basic online courses from website such as, Learningtree or Traininghott, however you could also do a quick search for short courses in your area.
Is Unix certification required for all computer jobs?
No, Unix certification is not required for all computer jobs, however it is useful to have some familiarity with Unix and all the different systems that computers run on. On top of that, you would also want to have a specialty in order to make more money.
Where can I find more information on unix certification ?
There are many different types of Unix Certification depending on what your career goals are. Check out Unix.org to find out information on the different certifications and for great test prep materials and tips.
Is Linux part of Unix or it is an advanced version of Unix?
It's neither. Linux is its own family of operating systems. It is modeled after Unix and shares many design goals, but it is not completely inter-operable. Also, to be legally called a "version of Unix", an operating system must go through a rigorous and expensive certification test, which no Linux distro has currently done. No. Linux is not an *anything* Unix.
Where do you find unix source code?
The true Unix source code is copyrighted; it doesn't exist anywhere specifically on the net. If you are interested in how something works in Unix you are better off looking at the Linux source code that accomplishes that task.
What is the difference between Linux and Unix?
To put it very generically, Linux is an operating system kernel, and UNIX is a certification for operating systems. The UNIX standard evolved from the original Unix system developed at Bell Labs. After Unix System V, it ceased to be developed as a single operating system, and was instead developed by various competing companies, such as Solaris (from Sun Microsystems), AIX (from IBM), HP-UX (from Hewlett-Packard), and IRIX (from Silicon Graphics). UNIX is a specification for baseline interoperability between these systems, even though there are many major architectural differences between them. Linux has never been certified as being a version of UNIX, so it is described as being "Unix-like." A comprehensive list of differences between Linux and "UNIX" isn't possible, because there are several completely different "UNIX" systems.
What operating system often used for server applications is a scaled-down version of unix?
This unenlightened question is found on many A+ certification exams, First, I will tell you the that they want. Then I will tell you why there is no correct . The that they want you to write in is "Linux." This is in spite of the fact that Linux scales even higher than Unix and has more features, thereby making most Unix implementations the "scaled-down" operating system. In order for something to be legally called a "version of Unix", it must undergo a rigorous certification process. No Linux distro has ever undergone this process, and so cannot be called a "version" of Unix. So then you would have to look at what certified Unix systems are commonly used in the server market. The only certified Unix systems still commonly used on the server market are Solaris 10, AIX and Mac OS X. All three of these systems scale very highly, which makes them unsuitable as an .
How can you learn all of the Unix commands?
It would take a very long time to learn all of the Unix commands, and frankly, that isn't necessary. Most Unix users have a subset of commands they use all the time, and that is how they learn them.
What servers were discused in network plus?
Network+ is officially a "vendor neutral" certification. However, a candidate for the designation is expected to have knowledge about Windows Server 2003 and Unix/Linux servers.
What is the normal monthly cost of leasing a dedicated UNIX server that provides between 100 and 125 GB of bandwidth?
Leasing a UNIX server can be anywhere from $9.95 a month to $200. For a minimum of 100 GB it wil start off around $200.
In a UNIX server what can take the form of a disk partition or it can be in a file?
Vitual Memory
