Using a uniform extent size for all segments in a tablespace eliminates free space fragmentation and encourages high performance. However, this requires grouping segments by extent size to balance the number of extents per segment, leading to wasted space from excessive extent sizes. Extent sizes of 128 KB for small tables, 1 MB for large

There are two main types of software. • Systems software and • Application software System software Includes the programmes that are dedicated to managing the computer itself. Such as • Operating system • File management utilities • Disk operating system Operating system (OS) Software that manages computer hardware and software resources provides common services for computer programmes. All computer programmes except firmware, require an operating system to function. For example, Microsoft windows

The Linux file system is ordered in a structured hierarchically tree. This file system is a tree shaped structure, where the root of the tree is called the file system root and beneath the root are directories. The root of the file system is usually stored on the partition of a disk and combing one partition with the file system is known as mounting a file system. …….. The Linux architecture handles all of the types of files by hiding the implementation details of any single file type behind a

Department needs to determine what file systems are mounted on his Linux computer because he is not sure that the DVD/CD-ROM drive is properly mounted. Explain the steps he should use to determine the mounted file systems, and also note which file system should be mounted for the DVD/CD-ROM. To determine what file systems are mounted on his Linux computer, first he must access the command prompt or open a terminal window. Once there, type “mount” to see which file systems are actually mounted. Here he

Introduction The basic definition of an operating system is a program that provides an interface to interact with the computer. It manages the computer’s hardware and software and provides a platform for other application programs. This report discusses the various aspects of an operating system with respect to Microsoft Windows which is a family of proprietary operating systems and Linux, which is a sub-category of UNIX. Operating systems thus not only provided a platform for interaction between

topic of computer forensics. Computer forensics involves carefully collecting and examining electronic evidence that not only evaluates the damage to a computer as a result of an electronic assault, but also to recuperate lost information from a system to prosecute a criminal in a court of law. Since security is such an important factor in technology, it is crucial for any type of computer professionals to understand the aspects of computer forensics. Seeing that technology is such a major part
