Subtopic 6: Job management and protection; include a serious discussion of security aspects

The most commonly leveled criticism of operating systems is the inherent lack of security they have (Funell, 2010). Defining operating systems to have partitioned memory is just the start, as Microsoft learned with their Windows NT platform. Dedicated memory partitions by user account can be hacked and have been (Funell, 2010). The need for greater levels of user authentication is required, including the use of biometrics for advanced systems that have highly confidential data within them. The reliance on security-based algorithms that also seek to analyze patterns of use to anticipate security threats are increasingly in use today (Volkel, Haller, 2009). This aspect of an operating system can capture the levels of activity and the patterns they exhibit, which can provide insights into when a threat is present or not. The use of predictive security technologies, in addition…...

To some users of personal computers, who state, never trust a computer that you cannot lift; the IBM has been viewed, more often than not, as an enemy, and according to Byte, the computer magazine, this was because of the fact that the IBM company rose to fame mainly on the basis of its mainframe computers, that were large and forbidding, and overwhelmingly bulky. This was probably why, when the rest of the world was eyeing the emerging opportunities in the minicomputer market, the IBM never paid any attention, and even though IBM did succeed in capturing a large chunk of that market, it did not happen until Digital had captured the minicomputer market and had grown into a large corporation.
In the past few years, IBM has agreed to change the ways in which it conducts its business, and adapt to the changing times when the prices of computers…...

Computer Maintenance Importance of Hardware and Software for the Computer
Computer hardware refers to the physical entities of a computer like a motherboard, keyboard, mouse, RAM, hard drive etc. These components are designed to perform particular functions that are directed by the software. The hardware components are used to power and control the computer making is usable. Most of the hardware components are mostly hidden meaning that they are not seen and are enclosed within the casing of the computer. Hardware and software are interconnected. Without software hardware of the computer would not have any function. Computer hardware is limited to the specific tasks that are taken independently. Software consists of the instructions that tell the hardware how to perform a particular task. Software has the ability to perform numerous tasks as opposed to hardware which only performs mechanical tasks that it is designed for. Software is important because it offers the…...

This is what creates the continual need to share literally everything going on in their lives, as each post releases a significant dopamine rush (Charman-Anderson, 17, 18).
Dopamine is also the reason why the many forms of computer addiction are so difficult to treat. ith anonymity comes the opportunity to create multiple identities or personas online (Soule, 66, 67). This is what leads employees who have Internet addictions to create many different online identities, giving them ethical and moral leeway they would never give themselves. This aspect of personas and the forgiven unethicacy of conduct of personas is a key factor in online crimes committed by employees during company hours (Nykodym, Ariss, Kurtz, 82, 83). The personas of the addicted computer addicts are orchestrated for specific dopamine-driven production to fuel and feed habitual behaviors online

(Quinn 180). These strategies to ensure a steady supply of dopamine may not even be obvious…...

In some areas it will be used for more populist applications such as, in schools to introduce students to the discipline and within an environment that will give opportunity for participation of non-academics in academic discussion.
Conclusion

Computer has in a great deal widened the world's knowledge. As the fastest technology that has ever evolved, it has given opportunity for the children and adults, for personal, academic and commercial use. It has made communication to be easier; people get to know what is happening in the other parts of the world instantly. Information and data entering and saving has been made convenient and even easy.

Computer Contracting
Contracting Opportunities for a Computer Component Manufacturer: Trends in Federal Spending

The pace of technological development is now faster than it ever has been at any other time in human history, and this pace has been steadily increasing for several decades. The emergence of the computer in the first half of the twentieth century could not have foretold the power and mobility that these devices would provide a few short generations later, nor the opportunities that continuing advancement and technological growth would supply to businesses. For Vigilant Technology, a manufacturer of computer components, the opportunities are virtually endless. Selecting the most profitable route forward can be made more difficult by the abundance of choices, yet an examination of the current contracts being offered by the federal government can help indicate the large-scale trends needed for long-term profits, not to mention providing immediate short-term gains in terms of the contracts themselves.…...

Computer clustering involves the use of multiple computers, typically personal computers (PCs) or UNIX workstations, multiple storage devices, and redundant interconnections, to form what appears to users as a single integrated system (Cluster computing). Clustering has been available since the 1980s when it was used in Digital Equipment Corp's VMS systems. Today, virtually all leading hardware and software companies including Microsoft, Sun Microsystems, Hewlett Packard and IM offer clustering technology. This paper describes why and how clustering is commonly used for parallel processing, batch processing, load balancing and high availability.
Despite some challenges such as achieving transparency, mitigating network latency and the split-brain problem, clustering has proven to be a huge success for bringing scale and availability to computing applications. Hungry for even more efficient resource use, IT departments are now turning their eye on the next evolution of clustering called grid computing.

Other partnerships with software companies provide HP with personalized value-added services for broadband Internet services and solutions.
Analysis of Compaq's competitive advantage over HP and other computer companies show that even though it has had experience with it servicing, its focus on small- to medium-sized computer companies did not, apparently, induced growth within the company, even though it services comprise 30% of the company's total revenue. The stagnation of growth illustrates how it servicing in Compaq is still on its preliminary stage, primarily because of the small scope of its clientele, even subsisting to "older" computer products, such as Tandem and Alpha, for use in its it services and consultancies.

Looking at the competitors of HP-Compaq, three major companies emerged as the leaders of the it service market: Electronic Data Systems (EDS), IBM, and Unisys. EDS' advantage is that it has a partnership with Dell, offering services such as help-desk service,…...

The first of these was co-designed with Sony, and established the modern layout for laptop computers that has remained popular ever since.
In 1994, Apple revamped its Macintosh line with the introduction of the Power Macintosh, which was based on the PowerPC line of processors developed by IM, Motorola and Apple. Apple's operating system software was adjusted so that most software written for the older processors could run in emulation on the PowerPC series.

After an internal power struggle with new CEO John Sculley in the 1980s, Jobs resigned from Apple and went on to found NeXT Inc., which Apple ultimately bought. This move brought Jobs back to Apple's management. On July 9, 1997, Gil Amelio stepped down as CEO of Apple after overseeing a 12-year record low stock price and crippling financial losses. Jobs stepped in as the interim CEO and began the critical restructuring of the company's product line.

(but they are these days more and more used around the globe)
The common characteristic of all input devices is that they encode or convert information of various types into data that can enter a further processing phase performed by the computer system. Output devices decode the data into information that can be easily understood by people, which are ultimately the users of a computer. This way, the computer system may be viewed as no more than a data processing system.

As far as electromechanical engineering technology is concerned, it enables engineers to design automated systems. Students need to learn to use computers, math, and advanced science in order to design such systems. Learning how to install and test robotics equipment is also important, and is performed by using computers.

Even apparently simple devices, such as candy machines, involve various technologies. For instance, the little rollers (a mechanical device) pull the coin…...

In the same year, the founders started a new company for computer development called the Eckert-Mauchly Computer Corporation. By 1949, this company launched the BINAC or Binary Automatic computer. This computer made use of magnetic tape for the storage of data. Then this company was bought by emington and Corporation and the name was changed to Univac Division of emington and. This company was the organization to bring out UNIVAC which is one of the originals of the type of computers that are used today.
