Technological advancement

The world has witnessed a great deal of technological advancement, specifically in the field of information and technology (IT). Particularly, the IT sector has witnessed the advent of computers which use the in-and-out electron movements into transistors. This is what has come to be known as the photonic computing; a technological phenomenon which uses light particles (photons). These are produced by in the place of the electrons by the lacers.

The Advantages of Using the optical (photonic) communications in future chip multiprocessors (CMP)

There are many merits (than demerits) which emanate from the use of the optical (photonic) communication in the CMP. First and foremost, the use of the photonic communications is bound to guarantee much faster connectivity and transactions, compared to the electrons.

This is due to the fact that light has the ability to travel approximately 30 centimeters within a nanosecond (Forestieri, 2005).

At the same time, the transmission of the photons, compared to the electrons, is bound to convey larger amounts of data and in (an almost) instantaneous manner. This is because the photons have the highest bandwidth.

Advantages to using optical communications

The optical communications is obtained through the use non-linear reflective indexing materials. The importance of optical components communications is based on the fact that its optical transistors effects are able to be dispensed in the creation of logical gates which are to be subsequently assembled into higher levels of the computer's CPU components.

The above use of the optical communications remains beneficial, since optical communications components use silicon photonics, leading to very minimal consumption of power.

This allows the deliverance of the performance-per-watt; a feat which remains unattainable as far as the use of all the electronic interconnects goes (Guo, 2002).

The two inherent limitations of photonic networks that electronic computing can solve in relation to the size or scale of the components being discussed

The advantage electronic computing has over the photonic networks is that it its use enables a smaller band of photon frequencies to represent more bits in binary number systems. Herein, electronic computers specifically use about 128 bit-position logic. The magnanimity of this is seen in the fact that on its own, 123 billion bit positions are contained by a single visible spectrum (Shacham, Bergman and Carloni, 2007).

Another advantage associated with electronic computers is that it allows the transfer of data over long distance at greater rates. This is due to the fact that electrical lines remain adequately larger. Optical computer communications on the other hand support lower amounts.

Characteristic of a mesh network is important to the experiment

Since a mesh network requires the employment of two or more connections, it remains quite clear that the experiment is likely to seek to ascertain the best form of mesh network: whether full mesh or partial mesh typology. To this effect, it is highly possible that direct connectivity of nodes to each other or the selective connectivity of only some nodes is to characterize this experiment.

The pros and cons of employing this emergency communications design within an area of the U.S. prone to natural disasters

As divulged upon by Takahashi and others (2007), the importance of this experiment is that it will antecede the discernment of the best broadband access systems which are to be deployed as a way of attenuating the digital divide the culmination of this above research is the provision of the medical care even right within the vicinity of the remotest of areas such as the Old Yamakoshi Village.

Conversely, the negativity to be realized from this undertaking is that large cascading buildings are bound to obstruct radio signals from the targeted party due to their large shadows. This is as far as far as the urban center is concerned. As touching on the rural setting, trees, hills and suchlike features are likely to causer the obstruction.

Conclusion

These above accruals will be stemming from the precedence set in by network expansions and the planting of self-healing architecture. This will greatly reduce the cost of operation and implementation as the facilitation of mobile networks is made a reality.

 

Computer Forensics Technology

Sample Essay

Answer 1

 The fact that computer forensics tools and methods can be successfully use to identify user passwords, computer logons, as well as other transparent information is absolutely correct. A simple example of this can be the extraction of password through file sharing. If a file sharing is enabled on a computer, then services such as NetBIOS can be sued to retrieve sensitive information about the system, such as the user names, configuration of the system as well as registry keys. These pieces of information can then be used to allow for a brute force password attack against any Windows NT system.  Furthermore, on a network, software such as packet sniffers can be used to extract data from the packets travelling a particular segment of a network, which can contain confidential information such as user credentials.

A simple utility which is often ignored called FINGER, can also be used to extract information about user logons remotely on computers on which the service has not been disabled.

With regards to identification, detection and extraction of information that is transparently moved between different components of a computer, forensic tools allow the computer forensic experts to have a look at data that is generated from past activities on the computer. This data may be found in the swap files that contain temporary data generated by the various programs. This data may not only provide information about the usage of the program but also provide clues about the users credential and other information that is not saved in user files. Forensic tools can also have a look at data in file slack and unallocated file space, which is unreadable by the user in normal circumstances. This form of data can be categorized uniquely as ambient data and may span up to 50% of a computer hard drive. This ambient data may contain email fragments, word processing fragments, directory tree snapshots as well as remnants of any activity that has occurred in past work sessions on a computer. These chunks of data, when read, may provide important information and can prove to be an important clue for computer forensic expert looking for evidence, but these activities are only made possible with the help of computer forensic tools (Vacca, 2005).

The Technological Revolution: How Computer Applications Speed up Company Operations

Technological advancements have created many possibilities for different businesses today. Innovations like sophisticated computer software have augmented employee performance. Businesses also use different applications to lighten the load of their operations. Tasks like record keeping, article writing, imaging, and storing data can be done via these applications. Listed below are a few of the computer applications that companies can use.

Internet Browsers

Connecting to the internet is essential since communication with customers and other business partners must be conducted online. Companies can use an application known as a web browser to access the internet. Web browsers enable companies to compose and send e-mails, and browse the web for resources. Some of the functions of an Internet browser may include tab browsing, webpage bookmarking, and toolbar customizing.

Multimedia applications

Advertising agencies need to create various materials for their clients.

In order to meet their clients’ needs, these companies use multimedia applications to create visual artwork and videos. Applications, like Adobe Premiere, conceive, create, and edit videos and photos. Moreover, editing, re-sizing, and uploading pictures can be done via photo editing applications.

Spreadsheets

To keep track of accurate data, companies use spreadsheets included in software bundles like Sage Timberline software.

A spreadsheet is an application with cells arranged in rows and columns for the information input. Users do not have to worry about re-entering and manually calculating figures with spreadsheets. Spreadsheets are highly versatile and packed with different functions. Businesses use spreadsheets to encode employee performances, account company sales, and analyze financial reports.  

Word processors

When typewriters became obsolete, word processors became the main tool for writing and editing printable supplies. Unlike typewriters, word processors are built with more functions for simpler encoding. Users can add pictures, change the font and font sizes, and delete any errors. Word processors may be used for keeping records, writing reports, and creating electronic messages. A number of applications of this type are accessible in software program bundles like Sage Accpac ERP.

The collective database enables users to quickly select specific data. It also functions as an electronic filing system. Database programs have advanced features other applications may not have. For example, a database system allows its users to store an infinite number of contacts. Database programs like sage Timberline Estimating can speed up the procedure of accounting.

The Cloud Hosting & Computing ?New Era of Advance Technology

In a new era of computing the cloud computing is very famous upcoming technology which is mostly used now days. In rapid advancement of internet and hosting technology the cloud hosting and cloud computing emerges possibility of business trends of a new web development and web hosting services and internet related services. The term cloud hosting via cloud computing is Internet-based computing technology used and website hosting ,web development and hosting services, In which shared servers provide resources, software, and data to computers and other devices on demand, as with the electricity grid and full technical support. Cloud computing is a natural evolution of the widespread adoption of virtualization, service-oriented architecture and utility computing. Details are abstracted from consumers, who no longer have need for expertise in, or control over, the technology infrastructure "in the cloud" that supports them.

It is mostly happening technology which is used by most of the organizations.

Cloud computing  mainly describes a new supplement, substitute, consumption, and delivery model for  ultimate IT services based on the Internet which helpful for internet based web hosting services, and it typically involves  all over-the-Internet provision of dynamically scalable and often virtualized resources. It is a byproduct and consequence of the ease-of-access to remote computing sites provided by the Internet.  This frequently takes the form of web-based tools or applications that users can access and use through a web browser as if it was a program installed locally on their own computer. Typical cloud computing providers deliver common business applications online that are accessed from another Web service or software like a Web browser, while the software and data are stored on servers. Most cloud computing infrastructures consist of services delivered through common centers and built on servers. Clouds often appear as single points of access for consumers' computing needs.

Cloud computing Assured Redundancy:-

The cloud hosting and computing will assured redundancy .Cloud Hosting replicates web servers on not just once but many times to make sure that when any of the physical server or virtual machine suddenly goes offline, the others will not be affected. Thus, the total uptime for the entire cloud is not affected when one server goes offline.  So the best way to do it is to ensure that web server can replicate your data in another machine. It is best that replication be done in more than one machine that is capable of uptime continuity.

Increased reliability and scalability with cloud computing:-

Because of the capability of cloud hosting to create multiple redundant sites, it increases reliability and lessens the possibility of outages. Cloud hosting can be trusted to keep you online when others are going offline. Another concern of industry players is scalability. We want that our website always work better and user friendly, interactive for this we will try to avoid unusual circumstance like bugs down, and crashes. This ability of a system to be enlarged to handle influx of work is called scalability.This is one very component of web hosting that cloud hosting appear to do at a lesser cost. With cloud hosting you can improve your scalability, from a one virtual machine to a group of servers.  

Major disadvantage with cloud hosting: Security :-

Moving on to security provides with cloud hosting is little be confusing, if not controversial issue with cloud hosting. The industry is split between users thinking that security is risky with cloud hosting and users who believe that security is better with cloud hosting. Security concerns are mainly due to the centralization of data. Others argue that cloud hosting takes away the some control on sensitive information and it lacks security features for stored kernel. Another argument is that security is riskier when data is shared and distributed on a bigger number of devices. Pro-cloud hosting would tell you that such is not the case.
