processor essay Essay Example processor essay Essay processor essay Essay Every PC has a Central Processing Unit (CPU) this acts as the brain of your system. It connects to the Motherboard and works alongside the other components processing many instructions at the same time between the different hardware and memory systems. Advancements in CPU technology now mean systems typically come with Dual Core, Triple core or Quad Core processors (on one single chip) instead of the traditional one core per chip. Now the total number of Cores can slot into a socket as before and a single heat sink and fan can keep everything to the right temperature. Types of processors: Intel Pentium Dual Core Processors The Intel Pentium processors with Intel dual-core technology deliver great desktop performance, low power enhancements, and multitasking for everyday computing. Intel Dual Core 13 Processors Intel Core 13 dual core processors provide 4-way multitasking capability with built-in performance headroom for software upgrades. Intel Dual Core 15 Processors Intel Core 15 processors deliver the next level of productivity. With Intel Turbo Boost Technology this quad-core processor with 4-way multitasking capability delivers extra speed whenever you need. Intel Dual Core 17 Processors The Intel Core 17 processors deliver best-in-class performance for the most demanding applications. This quad-core processor features 8-way multitasking capability and additional L3 cache. My personal view is there is little difference between using both makes and have run many stable and fast systems using both makes. The AMD processors do tend to run hotter than the Intel versions, but with a suitable fan this is easily kept under control. How processors works: The Central Processing Unit (CPU) Figure 1: The Central Processing Unit The computer does its primary work in a part of the machine we cannot see, a control enter that converts data input to information output. This control center, called the central processing unit (CPL]), is a highly complex, extensive set of electronic circuitry that executes stored program instructions. All computers, large and small, must have a central processing unit. As Figure 1 shows, the central processing unit consists of two parts: The control unit and the arithmetic/logic unit. Each part has a specific function. BeTore we Olscuss tne control unlt ana tne arltnmetlc/loglc unlt In aetall, we need to consider data storage and its relationship to the central processing unit. Computers se two types of storage: Primary storage and secondary storage. The CPU interacts closely with primary storage, or main memory, referring to it for both instructions and data. For this reason this part of the reading will discuss memory in the context of the central processing unit. Technically, however, memory is not part of the CPL]. Recall that a computers memory holds data only temporarily, at the time the computer is executing a program. Secondary storage holds permanent or semi- permanent data on some external magnetic or optical medium. The diskettes and CD-ROM disks that you have seen with personal computers are secondary storage evices, as are hard disks. Since the physical attributes of secondary storage devices determine the way data is organized on them, we will discuss secondary storage and data organization together in another part of our on-line readings. Now let us consider the components of the central processing unit. 0 The Control Unit The control unit of the CPU contains circuitry that uses electrical signals to direct the entire computer system to carry out, or execute, stored program instructions. Like an orchestra leader, the control unit does not execute program instructions; rather, it directs other parts of the system to do so. The control unit must communicate with both the arithmetic/logic unit and memory. The Arithmetic/Logic Unit The arithmetic/logic unit (ALL) contains the electronic circuitry that executes all arithmetic and logical operations. The arithmetic/logic unit can perform four kinds of arithmetic operations, or mathematical calculations: addition, subtraction, multiplication, and division. As its name implies, the arithmetic/logic unit also performs logical operations. A logical operation is usually a comparison. The unit can compare numbers, letters, or special characters. The computer can then take action based on the result of the omparison. This is a very important capability. It is by comparing that a computer is able to tell, for instance, whether there are unfilled seats on airplanes, whether charge- card customers have exceeded their credit limits, and whether one candidate for Congress has more votes than another. Logical operations can test for three conditions: Equal-to condition. In a test for this condition, the arithmetic/logic unit compares two values to determine if they are equal. For example: If the number of tickets sold equals the number of seats in the auditorium, then the concert is declared sold out. Less-than condition. To test for this condition, the computer compares values to determine if one is less than another. For example: If the number of speeding tickets on a arlvers recoro Is less tnan tnree, tnen Insurance rates are $425; otnerwlse, tne rates are $500. Greater-than condition. In this type of comparison, the computer determines if one value is greater than another. For example: If the hours a person worked this week are greater than 40, then multiply every extra hour by 1. 5 times the usual hourly wage to compute overtime pay. A computer can simultaneously test for more than one condition. In fact, a logic unit can usually discern six logical relationships: equal to, less than, greater than, less than or equal to, greater than or equal to, and not equal. The symbols that let you define the type of comparison you want the computer to perform are called relational operators. The most common relational operators are the equal sign(=), the less-than symbol(). Registers: Temporary Storage Areas Registers are temporary storage areas for instructions or data. They are not a part of memory; rather they are special additional storage locations that offer the advantage of speed. Registers work under the direction of the control unit to accept, hold, and transfer instructions or data and perform arithmetic or logical comparisons at high speed. The control unit uses a data storage register the way a store owner uses a cash register-as a temporary, convenient place to store what is used in transactions. Computers usually assign special roles to certain registers, including these registers: An accumulator, which collects the result of computations. An address register, which keeps track of where a given instruction or piece of data is stored in memory. Each storage location in memory is identified by an address, Just as each house on a street has an address. A storage register, which temporarily holds data taken from or about to be sent to memory. A general-purpose register, which is used for several functions. Memory and Storage Memory is also known as primary storage, primary memory, main storage, internal storage, main memory, and RAM (Random Access Memory); all these terms are used interchangeably by people in computer circles. Memory is the part of the computer that holds data and instructions for processing. Although closely associated with the entral processing unit, memory is separate from it. Memory stores program instructions or data for only as long as the program they pertain to is in operation. Keeping these items in memory when the program is not running is not feasible for three reasons: Most types of memory only store items while the computer is turned on; data is destroyed when the machine is turned off. If more than one program is running at once (often the case on large computers and sometimes on small computers), a single program can not lay exclusive claim to memory. There may not be room in memory to hold the processed data.

buy custom Developing Groups into Teams essay A team is made up of a group of people who are connected together in a common purpose. Teams are normally developed to conduct particular tasks that are complex, and have many co-dependent subtasks. A group in itself does not automatically make up a team. Members make it up with complementary talents and generate synergy by a coordinated effort that allows each member to minimize their weakness and maximize their strengths. Team members are required to work together and help each other so that each member realizes their true potential. By doing so, they create an atmosphere that allows each member to exceed their limitations. Teams size and a composition are known to have an effect on team processes and outcomes. The optimal composition and size of a team varies according to the task it handles. This paper will seek to discuss how groups can be developed into teams. There are several strategies that an organization can employ in order to nature the conversion of groups into teams. First, the organization has to develop common goals and vision that its members should try to achieve. Unless a common vision and a goal are set for a given undertaking, and each member holds the one goal and vision of the shared destination, it would be very difficult to achieve the set targets as members will be confused and hobbled along the way (Jungalwalla 200). Lacking a common direction, such a group will be divided into small fragments, thereby it will lose energy as the members move against each other as opposed to a team. To achieve a common goal and a vision, several tasks may be undertaken. Team members may record their perception of teams common vision and goals; then the differing perceptions may be considered. This task will help present a simple evaluation of the extent to which the group shares common visions and goals. Passion is an important aspect f or success. In developing common visions and goals, one may find out what visions and goals that are desirable for the organization the team members are passionate about (Jarod 2009). There should be a clear distinction between common and individual goals. Teams may share similar visions and goals, but may have different roles in a collaborative undertaking. Each member in the group should express their individual roles in ways that convey how that role contributes to the common visions and goals of the organization. When collaborative goals are set, benchmark and stretch goals have to be considered. Benchmark goals are said to be the minimum one can accept from themselves as professionals while stretch goals can be described as reach for the stars goal, which should carry considerable uncertainty as to its practicability. This will ensure that a team keeps motivated, and endeavors for improvement even beyond perceived restrictions (Junggalwalla 2000). Diversity of people in a group can be its greatest threat or asset; if a group is well harnessed, it can be a tool to develop a very good team and achieve high goals. The important factor here is the ability to appreciate diversity, to know its importance and to manage it. One can start by leading by example. If a leader is seen not to value diversity, the group members will not do it too, thereby developing a poor team. A team survey that draws attention to diverse work styles and roles within the team should be undertaken. A team map may be developed that shows which preferences and roles are well represented and which are not. The team could be then involved in giving strategic advice to themselves about further development of the team. Furthermore, teams training and development schedules should incorporate topics based on understanding and management of diversity (Jungalwalla 2000). Effective communication is paramount in development of groups into teams. Strategies that enhance active listening and engagement of the audience in meetings may be used to foster good communication (Hardcastle 2006). In conclusion, many factors may determine how a group develops into a team. Common visions and goals, ability to harness diversity and effective communication are important aspects in development of a group into a team. Buy custom Developing Groups into Teams essay

Resume and Cover Letter Construction Essay Example | Topics and Well Written Essays - 500 words - 4

Resume and Cover Letter Construction - Essay Example This is a good question and it is very difficult to give a proper answer to it. The first and foremost concern is to pick an appealing style, which will be appropriate and relevant to the market of employment. It is relevant to use action verbs (removed, supervised, supported, expanded etc) and some self-descriptive words, such as ambitious, broad-minded, consistent etc are appealing to the employer. A great advantage of chronological resumes is the ability of an employer to trace the exact dates of a candidates places of employment. Another advantage is to see a logical development of one's career development. A chronological resume is one of the most suitable. It is very often difficult for employers to look through different skills of an employee. When a candidate changes his career field very often, then his resume can be a functional one. His main skills and abilities are listed and an employer can choose between available skills and potential of an employee. Combination Resumes are also known as "custom or hybrid resumes". These types of resumes are advantageous because they enable an employee to illustrate his experience with exact dates and to make an employer aware of exact dates/ a process of a careers development. It is difficult to focus both on dates and facts or to shift one's attention from dates to events. This is a resume without any proper formatting. It should be mentioned that this type of resumes is often challenging, but it is possible for an employer to scan pros and cons of the resume. Moreover, an employer can be not satisfied with a proper interpretation of certain points of resumes. With respect to the fact that every employer looks at resumes not more than 30 seconds, it is very important to include keywords and focus ones resume on a particular company (Professional Resumes the Easy Way).
