b) Construct a B+-tree index of the type shown in this chapter for the Player file, assuming that now there are many more records than are shown above. The file and the index have the following characteristics:

In the workplace today there are many different options for operating systems be they providers of server related services or end-user desktops there is a different Linux distribution for many different applications. There are also a number of advantages and disadvantages to adding onto or switching network operating systems within a company. In the following pages I

This paper analyzes and compares the differences between the Windows and Linux’s operating system in an enterprise. It emphasizes the features in these two operating system such as history, cost, security, user-friendliness, performance, and future trends. It shows how impactful these features can be when an enterprise chooses an operating system. The research in this paper highlights the pros and cons of an enterprise using one operating system or the other. It directs the readers to have a better understanding on which operating system is better for specific instances. Readers will have an enhance perception on Windows and Linux and the platforms they serve. In our paper we try to fully analyze Windows and Linux’s operating system, so an enterprise can choose the best operating system for themselves.

B. Matching type. Match concepts in column left with the best answers in column right. Write letters only.

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

Both Windows and Linux come in many different forms. All the different forms of Windows come from Microsoft, the various distributions of Linux come from different companies (ex. Red Hat, SuSE, Linspire, Ubuntu, Mandriva, Knoppix, etc). Windows has two main lines: “Win9x”, which is consists of Windows 95, 98, 98SecondEdition and ME, and “NT class” which consists of Windows NT, 200 and XP. On a side note, Windows first had version 3.x which was made before Windows 95 by a couple of years. The various types of Linux are called distributions. All the Linux distributions released around the same time frame will use the same kernel, which are the guts of the OS. They will differ with the add-on software provided,

What is Operating System Security, Operating system security is the process of ensuring OS integrity, confidentiality and availability also OS security refers to specified steps used to protect the OS from threats, viruses, worms, malware or remote hacker. OS security include all avoiding-control techniques, which safeguard any computer information from being stolen, edited or deleted if OS security is included. OS security allows different applications and programs to perform required tasks and stop unauthorized interference. OS security may be applied in many ways. We 're going to discuss following topics in this article. A brief description about security and what are the types of encryption and what is Authentication, One Time passwords, Program Threats, System Threats and Computer Security Classifications.

The Linux was originally founded by Linus Torvalds. In 1991, he was a second year computer science student in Finland. He sought after an operating system that was similar to the UNIX system, but both UNIX and the hardware it ran on were excessively expensive. A UNIX version called Minix was available for free, but it did not reasonably meet his needs as it was simply an operating system for students, designed primarily as a teaching tool rather than an industry strength operating system. As a result, Torvalds studied Minix and proceeded to set out to write a new version. After six months of working to produce the new operating system, Torvalds made very little progress toward the utility of the system.

In Windows, you can run lots of different program programs. There are customized programs and off-the-shelf (common) programs. These allow you to do everything from running your bowling league to typing up a correspondence.

The Operating System of a computer. How does it work many say, what does it do other say. The operating system or some people in the world also call it the “OS,” which mean the same. The OS is the first program that gets installed and booted on to a new computer.
