When an organization opens up connections over the internet, it makes its network more vulnerable to hackers. Furthermore, in terms of security, the private network requires internet connections that are more stable so that it can get a reliable service as time and quality is a necessity in the Del Monte. Therefore, supplying them with the necessary information enables them to have access to information systems such as the corporate enterprise resource planning (ERP), data warehouse, and customer relationship management (CRM). This is because Del Monte required a system that employees could use to access the corporate network so that they could work as effectively as the employees in the corporate offices could. Technologies employed by Del Monte to address this primary concern include firewalls, encryption, IPSec, and AAA Server. Firewalls are used to offer strong barrier private network and the internet. Firewalls can be set as a restriction to numbers of open ports, the type of packets passed through and the protocols that are permitted through. Therefore, it should be noted that a person could have a good firewall first before implementing a VPN, although a firewall can also be used to destroy the sessions of VPN (Hoover 195). Another technology used is Encryption, which is a process that takes all the information that one computer sends to another and encodes it into a form that only the other computer will be able to decode. IPSec which refers to as internet protocol security protocol has the main function of providing improved security features like better encryption algorithms and extra significant authentication. Lastly, Del Monte employed another technology known as Authentication, authorization and accounting servers (AAA). This technology is mainly used to provide more security in a remote-access VPN surrounding. AAA checks the identity of the person sending a request, provides permission on what to be done, and then accounts for what a person actually does. Therefore, Del Monte employed these technologies in order to set up a secure website for the employees and partners to access the any internet connections. These technologies could keep hackers out and permit the authorized users’ in. The users are enabled to access only the parts of the network and data that they have been authorized to access. In addition, Del Monte supplies its employees with even secure connections for employees that work at home. The benefits enjoyed by both Del Monte and its employees include the speed of communication. Extranets provides access of information from anywhere especially from home in an effective and efficient manner to all partners by connecting intranets for urgent access to critical data. For instance, salesperson traveling far from the distributor is able to access information very fast and securely over the extranet, rather than calling a distributor for information. An extranet offers access to information in a very affordable price. For instance, companies are able to spend a very small amount in establishing and printing information for suppliers, distributors, and customers. Extranet also helps in reduction of hassles especially for an IT professional. It is sometimes hard to keep equipment and connections, while attempting to stay ahead of the access technology changes. Therefore, extranets tries to reduce these frustrations by permitting the IT organizer to outsource the difficult physical infrastructures. Extranets also tries to reduce long-distance phone charges. Hourly access fees charged by ISPs are up to 50 percent cheaper than the best available negotiated toll-free rates. Employees have a Cisco ASA 5500 Series Adaptive Security Appliance, which is a network device that offers a firewall and intrusion prevention system to keep hackers out and virtual private networking to encrypt and safeguard data flowing over the network. The device also enables the professionals to stay in contact while at home. If I were to choose whether to work at home or in a corporate, I would prefer working at home. This will thus enable me to work, at the same time attend meetings and do my own work at home. The company benefits from the devise in the general saving of money by allowing the company to erode expenses. I would prefer working at home rather than based in corporate office because it is easier to balance my personal life with work. For instance, working in an office requires daily commuting to and from work, which is hard to deal with when with children requiring to taken care of. Working from home also saves money and time and most of the time home environment is cool for working with no distractions from work mates, and I can plan my work in more organized manner. There is flexibility when working at home. My job can become flexible as long as I choose to be committed and reproductive. For instance, I can choose to work over the weekends, during the night and any time I am free. Therefore, working from home is very flexible since am able to make my own schedule and follow it to achieve the set goals. Working at home also gives time to spend with family members and friends.

Compare and contrast approaches to Tonality in New York Counterpoint, String Quartet number 8 by Shostakovich and Quartet by Webern Essay Example

Compare and contrast approaches to Tonality in New York Counterpoint, String Quartet number 8 by Shostakovich and Quartet by Webern Essay Example Compare and contrast approaches to Tonality in New York Counterpoint, String Quartet number 8 by Shostakovich and Quartet by Webern Essay Compare and contrast approaches to Tonality in New York Counterpoint, String Quartet number 8 by Shostakovich and Quartet by Webern Essay Essay Topic: Web Compare and contrast approaches to Tonality in New York Counterpoint, String Quartet number 8 by Shostakovich and Quartet by Webern.As these pieces are all from the 20th century, each of the composers added their own interpretations with regards to tonality. I aim to analyse each piece in the context of tonality in order to answer this question.New York Counterpoint (NYC) by Steve Reich is tonal which means it makes use of a conventional key which is B major. This can be seen from the five sharps of the key signature (and lack of D naturals and F naturals.) In fitting with the key of B major, all the notes Reich uses in NYC are from the B major scale which makes the piece entirely diatonic.Although the piece is tonal and diatonic, Reich does not make use of functional harmony. This can be seen because of the lack of cadences and chord structures. The notes of the ostinati in the first section (bars 1-26) are based on chords four and five (E major, and F# major.) For example, in the f irst two bars beat 1 of bar 1 uses the noes A and C (chord V) then, the three semi quavers contain all the notes of chord IV (EGB) and the A and F just after beat four are from chord V. In the second bar, this trend continues; just after beat 1 notes from chord five are used (F and C in clarinet 7 and C and A in clarinet 8 and so on. Here, it is important to note that the notes from each chord only sound with notes from the same chord, no overlapping of notes is heard.This is a contrast to what happens later in the piece. Later in the piece, tonal blurring occurs which means that the notes from different chords (chords IV and V) sound at the same which results in a slightly dissonant blurred harmony. There is a good example of this at bar 22 on the penultimate semiquaver beat: The live clarinet and clarinet 3 are playing an E and clarinet 6 is playing a B, these notes partly make up chord four. Also, on this same beat, clarinet 1 is playing an A# and clarinet 4 is playing an F# whic h make up chord 5. Because these notes sound together, the notes that are heard together is B, E, F#, A#. Some of these notes are from chord four and some chord five which results in the blurred tonality because they sound simultaneously. The reason that this tonal blurring occurs is because of phasing which is the process of adding a rest before or after the ostinati pattern. In this example, the live clarinet and clarinet six are one beat out of phase (crotchet rest at the beginning of bar 17) which means the ostinati pattern (C#, B, G#, E) now starts a beat later than it did in bar 1. (unclear)Another tonal device that Reich uses in NYC is the pulsating chords found at bar 27 in clarinets 7, 8, 9 and bass clarinet 10. Here, Reich adds extra dissonances to the chords. For example, on the last two semi quaver beats of bar 27 the notes that are heard are F# (cl7), B# (cl8), D# (b. Cl 9) and a C# in the bass clarinet 10. The notes make up the chord of B major (BD#F#) however the diss onance of a C# is added which creates unclear harmony. This dissonance is then extended when the chords change in bar 33. The notes heard are A#, D#, G# and E. These notes dont make up any conventional chord therefore, creating dissonance in the tonality.String quartet 8 by Shostakovich is a tonal work in the key of C minor, this can be deduced from the key signature and the accidentals of B natural. However, the C minor tonality is unclear and undermined from the start due to the different keys that each of the DSCH motives enter in. The cello enters in the key of C minor (D, Eb, C, Bnatural are all from the C minor scale.) The viola enters in the key of G minor (A natural, Bb, G and F# from G minor scale.) The 2nd violin enters in C minor (same notes as cello but an octave higher.) Finally, the 1st violin enters in bar 5 in the key of F minor (G, Ab, F, E natural all from F minor scale.)It is also interesting how Shostakovich uses all twelve notes of the chromatic scale by bar 6 w hich firstly shows no evidence for a diatonic nature in the melody but also links the piece (weakly) with serialist techniques.Although there is little strong evidence of functional tonality reflecting the arch form structure throughout the piece, there is an element of functional harmony found at the end of the first section. The first section (A) is from bars 1-27 (characterised by its contrapuntal exploration of the DSCH motif) and towards the end (from bars 24-26) there is a hint of a functional perfect cadence. This is because in bar 24 the notes used at beat 3 (lowest to highest on score) are: F, F, Ab, C. This makes up chord four in C minor.The next chord used is chord five in C minor at the beginning of bar 25, the notes uses are: G, D, Ab, Bnatural. This is a major version of chord five (G, B, D) with the Ab (that drops a tone to G in the 3rd beat of 25) acting as a 9-8 suspension. Finally, the chord used at the start of bar 26 is chord 1, the notes are C, C, G, C. However, there is the absence of the third note which shows whether the chord is a major or minor, so although the progression as gone IV, V, I (traditional, functional harmony) the functional harmony is not so strict because it is not a proper chord I used to finalise the cadence and section A.Another tonal device that Shostakovich uses is the presence of a double pedal note on notes one (C) and five (G) of C minor. This is found in the B section (bars 27-44) in the 2nd violin, viola and cello and lasts for 17 bars. Again, there is no 3rd to make the tonality of this double pedal major or minor, creating an ambiguous feeling by the use of bare, open fifths.Unlike NYC and Shostakovichs string quartet, Weberns Quartet is completely atonal. Its atonal because the piece is composed using serialist techniques. This means that Webern has created a tone row which is constructed from all 12 notes of the chromatic scale, not in order and none repeated. This has the effect of placing no importance o n a single note. The prime order tone row can be head in the tenor saxophone from bars 6-10.Because no importance is placed on a single note, it removes all the traditional and conventional elements that were laid out by 17th/18th/19th century tonality. The music isnt centred on the tonic, it has no key, it has no cadences and no deliberate harmonic chords that accompany a supporting melody. Although, there are chords they are simply a result of different perumatations of the cantus firums (prime row) overlapping, such as the climatic point at 22 and 23. In other words, any notes that sound together are not a result of deliberate harmony. There is no harmony in this work.However, it is still interesting how the structure of the Quartet is a traditional sonata form. Conventionally, a traditional sonata form would have made use of functional harmony with modulations and different keys for different sections. As previously stated, the Quartet does none of this therefore it is an exampl e of Webern using a traditional structure in a 20th century manner.
