...Q10.1 Magnetic tapes provide sequential access so it has to start and stop and reverse the head direction to search for the data. While the disk is rotating continuously and it can provide random access of data so the read write operation is easier in disks than the magnetic tape. Read/Write operation in hard disk most hard disk consist of several coaxial platters, these platters continuously move around the axis. the collection of number of platters forms a cylinder the read/write head is over the surface the head traces a circle on the surface of the platter known as track and each track divided into sectors and each sector contains a block of data to read the data from the disk the read/write head is located over the track that hold the data the time required to reach the data called the seek time after located the track the read/write head moved to the beginning of the sector that time required for that called rotational latency after locating the sector the transfer of data takes place so the total time is the sum of these three times, but it is not the same as the disk speed so a buffering provided by the disk controller Read/Write operation in magnetic tape they are non-volatile storage used for the backup and they come into layouts Linear and Helical and provide the sequential access mechanism. The storage technique known as data streaming. In Linear format the data divide into horizontal tracks while the Helical format has diagonal tracks. Q10.3 a/ Number of sectors...

... Whispering- requires the vocal folds to come together but not completely so there is a space between the arytenoid cartilages (432) Attack: The beginning of phonation by the bringing together (adduction) of the vocal folds (165) 1.Simultaneous Vocal Attacks- When the adduction of the vocal folds and the use of air from the respiratory system happen at the same time. (165) 2. Breathy Vocal Attack- When the use of air from the respiratory system happens before the adduction of the vocal folds (165) 3. Glottal Attack- When the vocal fold adduct before the air can be released from the vocal folds (165) Termination of phonation- Happens when the vocal folds abduct and the flow of air is stopped (147) Sustaining Phonation- Happens when the vocal folds say adducted allowing the air to flow through (168) Vibration how it's governed: Vibration is governed by elasticity of the vocal folds, the stiffness of the vocal folds and the quality of the vocal folds (160) Frequency- Determined by the number of times a vibration cycle is repeated in a specific amount of time (162) Period- A measure of vibration from a start time to a finish time (162) Opening Phase- The phase where the vocal folds are beginning to open (180) Closing Phase- The phase where the vocal folds are beginning to close but not completely (180) Closed Phase- The phase where the vocal folds are closed and there is no air escaping (180) Myoelastic theory of phonation- The elasticity of the vocal folds allows...

...Exercise One Nt1310 Week 1 In: Computers and Technology Exercise One Nt1310 Week 1 NT1310:Week 1 Telecommunications By: Kenneth Martin You are an IT Network Specialist and are required to develop the design of the company’s telephone system for its new building which will begin construction in a few months. In order to get a background which will help when developing the new system, your supervisor asked you to research the current Plain Old Telephone Service (POTS) currently used by the company. You must research the system components and report back to your supervisor , the Telecommunications Manager, within a week. 1. Describe a local land line phone system based on the following Landline Telephone Components: a. Local Loop a local loop is the wired connection from a telephone company's central office in a locality to its customers' telephones at homes and businesses. This connection is usually on a pair of copper wires called twisted pair. The system was originally designed for voice transmission only using analog transmission technology on a single voice channel. Today, your computer's modem makes the conversion between analog signals and digital signals. With Integrated Services Digital Network (ISDN) or Digital Subscriber Line (DSL), the local loop can carry digital signals directly and at a much higher bandwidth than they do for voice only. b. Central Office In telephone communication in the United States, a central office (CO) is an office in a locality...

...ITT TECHNICAL INSTITUTE NT1310 Physical Networking GRADED ASSIGNMENTS ------------------------------------------------- Student Professional Experience Project NSA SPE Project 1 (to be completed by the end of NT1310): Install, Configure, Test, Maintain and/or Document the Worksite Local Area Network and Its Components Purpose The purpose of the Student Professional Experience (SPE) project is to provide you an opportunity for work experience in your field or in a related field to add to your résumé. You may have an opportunity to serve your community or work for a local employer for a project that will take between 20 and 30 hours. Project Logistics Career Services will identify an employer with needs in the following areas: Network related tasks (mostly confined to the LAN and Microsoft Windows Server 2008 environments) Students are expected to practice various skills discussed in all the technical courses in Quarters 1 through 3 of the NSA program at an employer’s site on network related tasks (more confined to the LAN and Microsoft Windows Networking with Server 2008 environments) that would involve installation, configuration, testing, maintenance and documentation of the worksite network and its components, and to properly document the technical information in all involved activities. Such documentation will be used as the source material for Items 2 and 3 defined in the Deliverables section of this document. Possible example projects could...

But Best Practice dictates to move some of theese Flexible Single Master of Operation (FSMO) roles to seperate servers. If you only have one domain controller (not recommended), there is nothing to do since all roles must be on this server, but if you have multiple servers you should move some of theese roles on to more servers. It is also important to be aware of what servers are Global Catalog servers, especially if you have more than one domain and even if only one domain, they will be prefered by applications like Exchange server. It is recommended to place the forest roles on one Domain Controller (DC) and the domain roles on another server. If not all Domain Controllers are Global Catalog servers, it is also important to place the infrastructure master on a server that is NOT a Global Catalog server. Recommended Best Practice setup of FSMO roles. Domain Controller #1 Place the two forest roles on this server. * Schema Master...
