MIS Essay question In this paper I want to share with you some information about MIS. I will try to be unbiased and laconic. One of the major roles of an operating system is to control processes. For instance, each process or job requires CPU resources, which the operation system must allocate. The function of CPU is to execute program instruction and coordinate the activity of the other entire unit. In other words the CPU is the brain of computer but it can do nothing without proper operation system.
The operation system is software, which controls all kinds of software and hardware resources of computer system. There are many kinds of operation systems and they all have their similarities and differences in the strategies of job scheduling and memory management. For example Windows is a bootable operation system, all files needed for the downloading are situated on the hard drive. At start up system read them and the download the operating system. On the other hand, most of the Mac OS code is in the ROM chips. It takes some time while the computer transfer the data from disks to peripherals and takes control over the RAM space.
Almost all widely used operating systems are multi-user systems. Such systems complicated the job of the OS because the majority of the OS are not dedicated for the multiplatform working space. But Linux operating system, which is POSIX-based multitasking system, is used as a high value, fully functional UNIX workstation for applications ranging from Internet Service to reliable work group computing. The popularity of Linux system is also in its freely distributing and exceptional stability.
The next question I want to discuss is cryptography. Cryptography has been around for centuries but its importance in the Information Age is paramount, so much so that corporations now often employ C-level Information Officers. Jim Settle, the retired director of the FBI's computer crime squad, was quoted in USA Today as saying, "You bring me a select group of hackers and within 90 days I'll bring this country to its knees. " He was talking about USA. Hackers are very advanced in programming and always try to automate cracks. Trojan horses, viruses, and worms are widely used.
There are many kinds of security technologies: operational technology, one-time passwords, firewalls, monitoring tools, security analysis tools, and cryptography. While the operational technology mainly defend the availability of data resources in a secure manner and maintain data, the cryptography secure the confidentiality, integrity, and authenticity of data resources, etc. The next question of my essay is Artificial Intelligence. Artificial Intelligence is one of the oldest areas of computer science, yet it is also one of the greatest unfulfilled promises of information technology. I want to discuss the three fields of AI: expert systems, neural networks and robotics. Experts systems are programming computers which make decisions in real-life situations (for example, some expert systems help doctors diagnose diseases based on symptoms) In spite the fact that expert system help in such fields as medicine and engineering, they are very expensive to produce and can be helpful only in very specific situations.
In 1980 expert systems represented the future of AI. Nowadays, the neural networks are proving successful in a number of disciplines such as voice recognition and natural language processing. Neural networks are the type of AI, which tries to imitate the way a human brain works. Such system doesnt use bits and bytes, instead it creates connections between processing elements, which play the role of computer neurons. The output is determined by the organization and the output. Neural networks are particularly effective for predicting events when the networks have a large database of prior examples to draw on.
Strictly speaking, a neural network implies a non-digital computer, but neural networks can be simulated on digital computers. (Neural Network) They are used in a voice recognition systems, industrial robotics, medical imaging, aerospace application. The robotics is the field, which combine both computer science and engineering. Robotics includes the process of creating robots (devices which can move and react to sensory impulse). Robotics is rather well used branch of science because robots are used in factories, in space in such surroundings where normal human being cannot survive, or where the high-precision jobs required. Still, robots are still too clumsy to use them at household ordinary chores.
Now, I want to discuss the challenges, both technical and societal, that RFID tags will present. By the next decade, UPC codes will be completely replaced by RFID tags. What are the advantages of an RFID tag? RFID or radio frequency identification changed the UPC (universal product codes). In contrast to UPC the RFID can be used just about everywhere where a unique identification system is needed and the working is very large, more than 90 feet.
The main advantages of RFID are carrying small or rather big amount of information, no line of sight is requiring for reading tags, increasing reading range, ability to read from and write to tags, reducing of human intervention, enhancing the access to information and durability. The next question will dwell on the data warehouses and FAC. Data warehouses have emerged as the dominant method for corporations to analyze their voluminous amounts of older transaction data. First American Corporation used their Vision Data Warehouse to help develop strategies to improve their customer relationships and increase profitability.
Unlike to the ordinary database, both data warehouse and FAC are powerful analysis tools that allow organizations to sort through large volumes of information and extract real business intelligence. Then, management utilizes this knowledge to make better decisions, therefore rapidly deriving real value from raw data. The recent proliferation of data warehouses implements a new customer-centric focus. It is based on it and for many firms plays role of quantum leap in the availability and quality of information. In such way FAC use Vision to align IT strategy with corporate objectives. The next question is the grid computing.
The grid computing is a form of network, which uses unused processing cycles of all computers in network for solving problems, which are too difficult for a single machine. The concept of grid computing, or utility computing, has emerged as a Just-in-time IT solution. The grid computing does require special software but the main challenge is that it allows harnessing the unused processing power of the user's computer. This method saves both money and resources. In this paragraph I want to discuss Internet telephony, including VoIP. VoIP is drastically changing the telecommunications industry.
VoIP is a method for taking analog audio signals, like the kind you hear when you talk on the phone, and turning them into digital data that can be transmitted over the Internet. (How VoIP Works) It can be rather useful because it gives more opportunity than ordinary type-chatting. With special software you can easily use Internet for making free phone calls. The standard ICQ plug-in has required software you just need to set up the speakers and the microphone. For example you can talk with Paris for hours and pay Italy for Internet connection. As we know Cellular companies are rolling out 3 G networks. 3 G are an ITU specification for the third generation of mobile communication technology. It may be compared with the digital PCS of second generation.
The benefits of the 3 G are the following: increasing the bandwidth, up to 384 Kbps when a device is stationary or moving at pedestrian speed, increasing to 128 Kbps in a car, and 2 Mbps in fixed applications. Great improvements of the speed connection, as you see. 3 G can work over wireless air interfaces such as such as GSM, TDMA, and CDMA. New EDGE air interface was specially developed for the needs of 3 G.
