...BASH SHELL Bash is a Unix shell written by Brian Fox for the GNU Project as a free software replacement for the Bourne shell .Released in 1989, it has been distributed widely as the shell for the GNU operating system and as a default shell on Linux and Mac OS X. It has been ported to Microsoft Windows and distributed with Cygwin and MinGW, to DOS by the DJGPP project, to Novell NetWare and to Android via various terminal emulation applications. Bash is a command processor, typically run in a text window, allowing the user to type commands which cause actions. Bash can also read commands from a file, called a script. Like all Unix shells, it supports filename wildcarding, piping, here documents, command substitution, variables and control structures for condition testing and iteration. The keywords, syntax and other basic features of the language were all copied from sh. Other features, e.g., history, were copied from csh and ksh. Bash is a POSIX shell but with a number of extensions. The name itself is an acronym, a pun, and a description. As an acronym, it stands for Bourne-again shell, referring to its objective as a free replacement for the Bourne shell. As a pun, it expressed that objective in a phrase that sounds similar to born again, a term for spiritual rebirth. The name is also descriptive of what it did, bashing together the features of sh, csh, and ksh. Early computers had a teletype machine with a keyboard for I/O. Later, glass terminals became the norm,...

...\maketitle \section{LP} \section{} \subsection{Question 1} A company buys a spare part with rate of 1 unit from a supplier per year. The supplier decided to not produce the product. But, it offers the company to order last time. The company uses these spare parts to assemble machines and machines are replaced in 3 years and the total demand of the spare part is Poisson distributed with mean 3 units. If company still has spare parts at the end of the life cycle, products can be sold at $8 as salvage value. Solution: c_{u} = 25-12 = 13 \\ c_{o} = 12-8 = 4 \\ CR = \frac{c_{u}}{c_{u}+c_{0}} \\ P_{x}= \frac{\lamda3^x.epsilon^-lamda}{x!}\\ \begin{table}[htbp] \centering \caption{emrenin tablosu} \begin{tabular}{ccccccc} X & P(x) & F(x) \\ \hline 0 & 0.050 & 0.050 \\ 1 & 0,149 & 0,199 \\ 2 & 0,224 & 0,423 \\ 3 & 0,224 & 0,647 \\ 4 & 0,168 & 0,815 \\ 5 & 0,101 & 0,916 \\ 6 & 0,050 & 0,966 \\ 7 & 0,022 & 0,988 \\ 8 & 0,008 & 0,996 \\ 9 & 0,003 & 0,999 \\ 10 & 0,001 & 1,00 \\ \hline \end{tabular}% \label{t1} \end{table}% \newline Q^* = 4...

...Acme Manufacturing Network Plan Ann Johnson IT/242 October 23, 2011 David Edwards Acme Manufacturing Network Plan Acme Manufacturing needs a new network plan implemented for corporate, three distribution centers in Chicago, Phoenix, and New York, and is expecting to expand with a new facility in China. A successful network design provides future growth within the organization. Meetings are scheduled weekly in the main Atlanta Headquarters conference room with the facilities from Phoenix, New York, Chicago, and China attending via telecommunications. The network plan will include the type of cabling needed for each facility, the equipment used to connect the different facilities, and the installation of Voice over IP (VoIP) and Virtual Local Area Networks (VLANs). Security measures are needed including firewalls and a backup plan. The lines required to carry the traffic on the network are leased T1 lines and a satellite connected overseas. T1 leased lines are used for the Atlanta, Phoenix, New York, and Chicago offices. China connects through a satellite service. A Virtual Private Network (VPN) connects wireless users to their designated department through mobile devices. Routers are used to direct communication between LANs and are needed at each department. Voice over IP (VoIP) has opened possibilities for more interactive communication across WAN networks. VoIP bypasses the need of conventional telephone hardware by transmitting voice over the existing data line...
