...thankful that you have given us the opportunity to prepare this report under your supervision and hope that this report will meet the standards of your verdict. Sincerely yours, (Syed Shohan Shah) On the behalf of the group EXECUTIVE SUMMARY In this modern age computer is a very essential in our everyday life. It helps our every work. Without computer we can not live without a single day. It has many parts like hardware which are touchable and software which are untouchable. Computer users may use a scoring system of evaluation when there are several competing proposals for a hardware or software acquisition. They give each evaluation factor a certain number of maximum possible points. Then they assign each competing proposal points for each factor, depending on how well it meets the specifications of the computer user. Scoring each evaluation factor for several proposals helps organize and document the evaluation process. It also spotlights the strengths and weaknesses of each proposal. Computer Hardware 1.0 Monitor Multiple technologies have been used for computer monitors. Until the 21st century most used cathode ray tubes but they have largely...

...IMPORTANCE OF SECURING DATA AND SOFTWARE MORE THAN COMPUTER HARDWARE IN AN ORGANIZATION BY DHUMISAN CHISI SUBMITTED TO MR MWEKHELA IN PARTIAL FULFILLMENT FOR THE COURSE FUNDAMENTALS OF INFORMATION SYSTEMS COURSE CODE CCC1073 THE MALAWI ASSEMBLIES OF GOD UNIVERSITY 23TH MARCH 2015 Information systems have long been at some risk from malicious actions or unplanned user errors and from natural and man-made disasters. In recent years, systems have become more at risk to these threats because computers have become more organized and, thus, more interdependent and accessible to a larger number of individuals. In addition, the number of individuals with computer skills is increasing, and intrusion, or “hacking,” techniques are becoming more widely known via the Internet and other media. In large organizations computers are kept in large scales and also store a lot of important data and information plus maybe softwares of the at most important. These softwares and information require to be kept safe and protected. It is the sole purpose of this paper to explain the reasons why it is important to secure the organizations data/information and computer softwares of an organization. Some of the information used in business organization requires special protection for confidentiality (to ensure that only those who need access to that information to do their jobs actually have access to it). Some of the information used in business organizations need protection...

What is known as software? what a computer can and cannot do How computer illiterate am I? 3 6/6/2013 Aspects of computer literacy One problematic element of many (though not all) "computer literacy" or computer education programs is that they may resort too heavily on rote memorization. Students may be taught, for example, how to perform several common functions (e.g.: Open a file, Save a file, Quit the program) in very specific ways, using one specific version of one specific program. 1 06/06/2013 4 6/6/2013 Aspects of computer literacy When a graduate of such a program encounters a competing program, or even a different version of the same program, they may be confused or even frightened by the differences from what they learned. 5 6/6/2013 Aspects of computer literacy This is one reason why major computer and software firms such as Apple Computer and Microsoft consider the educational market important: The often time-limited computer education provided in schools most often lends itself to note memorization, creating a sort of vendor lock-in effect whereby graduates are afraid to switch to competing computer systems. 6 6/6/2013 Aspects of computer literacy ...

...Shane Childers Mrs. Pascal Bailey English IV 23 Nov. 2013 Computer Engineering Throughout the world, engineering is perhaps the most necessary job in any context, whether it be designing buildings, roads, chemicals, or even software or hardware for a computer. In this day and age, this is more evident in the rising computer industry. As society progresses in the 21st century, the need for computer engineers of all kinds can only increase. Coming to realization with the increasing need for those interested in computer engineering, one could see how this would be an ideal field to study. With a diverse range of courses available for computer engineering, from writing software to designing hardware, and the ever increasing use of computers in general, it is easy to see why this career path is one worth pursuit. To start, there are two main paths of computer engineering, as stated previously, hardware engineering and software engineering. Computer hardware engineers research, design, develop, test, and manage the manufacture and installation of various computer hardware ("Computer Engineering"). According to the above website, hardware includes computer chips, circuit boards, computer systems, and equipment such as keyboards, routers, and even printers. If one were to go into this field of engineering, they would also learn of the electrical details which go into hardware engineering.

...Computer Organization The dictionary definition of the term “organizing” is “to put together into an orderly, functional, structured whole”. Therefore, this term applies to Computer Organization because it tries “to put together into an orderly, functional, structured whole” the main components of computers and the way computers are organized. Modern computer technology requires professionals of every computing specialty to understand both hardware and software. The interaction between hardware and software at a variety of levels also offers a framework for understanding the fundamentals of computing. Whether our primary interacts is hardware or software, Information Technology, Computer Science or Electrical Engineering, the central ideas in Computer Organization is the same. Thus, the emphasis of this is to show the relationship between hardware and software and to focus on the concepts that are the basis for current computers. The computer lies at the heart of computing. Without it, most of the computing disciplines today would be a branch of theoretical mathematics. To be a professional in any field of computing today, one should not regard the computer as just black box that executes program by magic. We, students of computing should acquire some understanding and appreciation of a computer system’s functional components, their characteristics, their performance, and their instruction. There are practical implications as well. In describing computer systems, a distinguishing...

...1. INTRODUCTION Specification point: Define a computer system Computers today are all around us in one shape or another. Whilst you are reading this page – how many computers are you aware of in the room? Maybe you are in a classroom right now and you are near to a: Mobile phones Calculator Watch Interactive white board Projector Printer Desktop computer Laptop And more probably. The point is that computers come in all shapes and sizes and are often built into other devices. But they share some common features. This mini-web will introduce you to a computer system. 2. A computer system A computer system is one that is able to take a set of inputs, process them and create a set of outputs. This is done by a combination of hardware and software. This diagram below shows you the idea of a computer system in its most basic form The computer system has one or more inputs to provide data. This data is then processed in some way. The outcome of the processing is sent to an output or it may be stored until some event happens to cause it to be output. For processing to take place, there needs to be a set of instructions of what needs to be done. This set of instructions is called a program. This system is called a stored-program computer. The very first computer in the entire world of this type was built in Britain in 1949 and was called the Manchester Mark 1. The beauty of this type of computer system is that it is flexible-the machine performs a different...

...Computer software From Wikipedia, the free encyclopedia Jump to: navigation, search "Software" redirects here. For other uses, see Software (disambiguation). Computer software, or just software, is a collection of computer programs and related data that provide the instructions for telling a computer what to do and how to do it. In other words, software is a conceptual entity which is a set of computer programs, procedures, and associated documentation concerned with the operation of a data processing system. We can also say software refers to one or more computer programs and data held in the storage of the computer for some purposes. In other words software is a set of programs, procedures, algorithms and its documentation. Program software performs the function of the program it implements, either by directly providing instructions to the computer hardware or by serving as input to another piece of software. The term was coined to contrast to the old term hardware (meaning physical devices). In contrast to hardware, software is intangible, meaning it "cannot be touched".[1] Software is also sometimes used in a more narrow sense, meaning application software only. Sometimes the term includes data that has not traditionally been associated with computers, such as film, tapes, and records.[2] Examples of computer software include: * Application software includes end-user applications of computers such as word processors or video games, and ERP software for groups of...

...Hardware and Software Firewalls Explained A firewall is a protective system that lies, in essence, between your computer network and the Internet. When used correctly, a firewall prevents unauthorized use and access to your network. The job of a firewall is to carefully analyze data entering and exiting the network based on your configuration. It ignores information that comes from an unsecured, unknown or suspicious locations. A firewall plays an important role on any network as it provides a protective barrier against most forms of attack coming from the outside world. Firewalls can be either hardware or software. The ideal firewall configuration will consist of both. In addition to limiting access to you computer and network, a firewall is also useful for allowing remote access to a private network through secure authentication certificates and logins. While many people do not completely understand the importance and necessity of a firewall, or consider it to be a product for businesses only, if your network or computer has access to the outside world via the Internet then you need have a firewall to protect your network, individual computer and data therein. Hardware Firewalls Hardware firewalls can be purchased as a stand-alone product but more recently hardware firewalls are typically found in broadband routers, and should be considered an important part of your system and network set-up, especially for anyone on a broadband connection. Hardware firewalls can be effective...

...Software and hardware are computer-related terms that categorize different types of computer related paraphernalia. Hardware includes every computer-related object that you can physically touch and handle like disks, screens, keyboards, printers, chips, wires, central processing unit, floppies, USB ports, pen drives etc. Software includes every computer-related program that you cannot feel with the physical senses for example, system operating system, an anti-virus program, the web browser, the memory, all data, reports etc. All storage devices that keep data safe and store it in some electronic form are hardware while all data in itself is software. Software is what makes the hardware function properly and to an optimum level. Sometimes, there is confusion between software and hardware because the two terms are so integrally connected. If you buy an anti-virus program you buy software but since it comes on a disk, you have also bought the hardware. The major confusion between software and hardware occurs relating to memory. Software defines the memory capacity of a computer but it depends on the kind of hardware ‘“ or memory chip ‘“ used in the particular computer. Software is of two kinds: Applications software: That is of individual liking and need. It can range from games to professional work-related programs like database management systems, word processors, spreadsheets etc. Systems software: This makes the computer run and thereafter, makes the applications software...

These firewalls ignore information that is not secured and comes from locations that are unknown and suspicious. Hardware firewalls can be stand-alone and/or in broadband routers. Hardware firewalls does not necessarily have to be configured and can protect all machines on a local network. Hardware firewalls examine packet headers by using a packet filter. Based on previously stored information and rules, the packet is then forwarded to its destination or dropped. Hardware firewalls determine whether the information packets are safe based on the ports and URL. 8/31/14 Software firewalls are installed on a specific computer as opposed to supporting a whole network. It protects against remote access to control your computer. It can also block the running of potentially unsafe applications on your computer. Software firewalls normally uses minimal system resources and runs in the background constantly to ensure protection for the computer. Software firewalls need to be kept up-to-date to ensure the best level of protection from newer viruses and malicious content. It is best to always test both hardware firewalls...
