database and fileservers are Linux servers. Linux is a UNIX system which implies that it has solid compatibility, stability and security features. Linux is used for the mentioned environments because these services require high security. Further, an increase of attacks on these servers can be observed. Additionally, the methods to prevent intrusions on Linux machines are insufficient. Further, the analysis of incidents on Linux systems are not considered appropriately (Choi, Savoldi, Gubian, Lee
The operating system (OS) is a collection of software to control the computer tasks and manage proper utilization of the hardware resources. The basic operating systems are the Linux, UNIX, Mac and Microsoft Windows. There are several and diverse components of an operating system that include but not limited to the file management, security, memory and process management. The following paragraphs present the comparison of basic operating systems with respect to the above given features (Solomon
In recent years, vehicle thefts are most important crux in the world. At the present time, the available anti theft vehicular systems are much more expensive.

Computer Viruses and their Effects on the Computer In our health-conscious society, viruses of any type are an enemy. Computer viruses are especially pernicious. They can and do strike any unprotected computer system, with results that range from merely annoying to the disastrous, time-consuming and expensive loss of software and data. And with corporations increasingly using computers for enterprise-wide, business-critical computing, the costs of virus-induced down-time are growing along with

Windows XP File Processing Within Windows there are two methods that a user or administrator can obtain access to files stored on the hard drive or media source. In the Windows operating system, files that are operating system specific (files needed in order for the operating system to work) are normally on the primary drive which is usually the C: drive. On a Windows based PC during the setup process, a user has the choice of where the operating system files are stored and what file system Windows
distance location of the sender and receiver within a thousand miles. Most of e-mail systems consist of an elementary text editor for composing messages, but many allow users to edit the messages using any editor they want. The message can be sent to the recipient by specifying the recipient's address. Most of message was sent in a text and image form, but some audio files also can be sent but with limited of file size. This application also is able to send the same message to several users at once
do several things at once, such as printing out one file while the user edits another file. This is a major feature for users, since users don't have to wait for one application to end before starting another one. 2. Multi-user The same design that permits multitasking permits multiple users to use the computer. The computer can take the commands of a number of users -- determined by the design of the computer -- to run programs, access files, and print documents at the same time. The computer
A Flat file database is a database that stores data in a single file (such as .txt or .ini). One record is held in each line of the text file with fields separated by delimiters. There is no structural relationship between the records. A list of names, CNIC number, address and phone numbers written on a piece of paper or typed using a type writer or word processor is a flat file database. This database file system stores all data in a single directory. There are no folders or paths used to organize
Information Systems 1. Definition of an Information System: An Information System is a combination of hardware, software, people, procedures and data that provides data processing capabilities for a business or organization. More sophisticated information systems provide the decision makers in a business (eg. the executives or managers) with on-demand reports and inquiry capabilities as well as routine periodic reports. 2. Capabilities of Information Systems: All information systems have
Task 1 (P1) Animation Techniques Animation is a simulation of movement created by displaying a series of pictures, or frames. Cartoons on television are one example of animation. Animation on computer is one of the chief ingredients of multimedia presentations. Movement – is what makes the animation that you are creating come to life. When creating movement some of the tools that you can use are: motion tweening, key framing and stop frame. Motion Tweening is a feature that allows you easily animate

The MP3 to CD player Comparison The late Tom Petty said, “I think that if people realize that with an MP3, you're only getting five percent of the sound that's there. But when you hear the entire thing... I think it would save the music business. It's such a drastic change.” Mr. Petty has a sober perspective on the purpose of the music player, regardless of the medium or brand. The MP3 player became an affordable and convenient device to enjoy ones favorite music, in a small and efficient formatted
Old PCs Back to Life MenuetOS is an extremely obscure operating system. It has a very low system requirement, and is mostly only used for outdated computers. It can run smoothly on a 50MHz processor with only 32MB of RAM (MenuetOS, 2010). MenuetOS also has desktop effects, such as transparent windows and three dimensional previews while switching programs. While MenuetOS is designed to run on older hardware, it’s a new operating system compared to others in existence. Linux has been around since 1991
File servers are an important part of any business. The file server is the central location of files for a business small or big. The file server can be a cloud accessible server which grants accesses anywhere. The file server can also be a dedicated server which is only used on the business network. I am going to touch on the specifications of a file server. This means I am going to go over CPU, memory, bus, DMA, storage, interrupts, input/output peripherals, and monitors of a files server. The

the laptop. The first model of these has a small screen which was black and white and was very slow and also expensive. They were only really used by businessmen and rich people. Now they have changed and have large colour screens and are of comparison in speed to that of desktop computers. The next development was that of mobile phones. It was at first thought never to take off with the large models, which needed a long charge for not much talk time. This changed when the phones which looked
