As in portraying computers and machines, the first-rateness is frequently made on the side of computer organization and computer architecture. The inquiry of internal working, structuring and implementation of a computer system are the parts of computer organization and architecture. Computer organization relates to the operational units and their interconnections that realize the architectural specifications. Computer organization, then, was a usually high-level description of the logic, memory and others. Organizational attributes include those hardware details transparent to the programmer, control signals, interfaces between the computer and peripherals, memory technology used. Computer architecture relates to the attributes of a system visible to the programmer. It is also have a direct impact on the logical execution of a program. Computer architecture was essentially a contract with software stating unambiguously what the hardware does. Architectural attributes include the instruction set, number of bits used to represent various data types, input and output mechanisms, techniques for addressing memory.
Most of computers nowadays may have the same aspects in architectural attributes but must be different in organizational attributes. Thus, there is a few comparison between some computer manifacturers in the view of the computer organization and computer organization. For example, these three computer manifacturers which is Lenovo, HP and Dell somehow may have their own similarity and differences in many aspects relate to the computer organization and architecture. There is a few points of each computer manifacturers (Lenovo, HP, Dell).
Lenovo took first place for the second year in a row because of its excellent, highly rated laptops. Lenovo has operations in more than 60 countries and sells its products in around 160 countries. With its eye-popping, HDR screen (an industry first) and long battery life, the ThinkPad X1 Carbon is the business laptop to beat, while the Yoga 920 has been a favorite consumer 2-in-1 in the past year. Lenovo was the world’s largest personal computer vendor by unit sales from 2013. It markets the ThinkPad line of notebook computers, IdeaPad, Yoga and Legion lines of notebook laptops, and the IdeaCentre and ThinkCentre lines of desktops. In 2018 Lenovo received 10 Editors’ Choice awards more than any other brand and a full 53 percent of its laptops scored 4 stars (out of 5) or higher.
HP had a strong, second-place showing in this year’s(2018) rankings, jumping from fourth place last year(2017). While users recommended every HP laptop they tested, the company received fewer Editors’ Choice awards than first-place Lenovo. A combination of very good overall review scores, great design and a wide variety of laptop options for every price range helped HP shine.
Taking third place for the second year in a row, Dell’s complete range of high-performance computer systems include: Dell Dimension and OptiPlex desktop computers, Latitude notebook computers, and PowerEdge network servers. Dell is an American multinational computer technology company based in Round Rock, Texas, United States, that develops, sells, repairs, and supports computers and related products and services. Dell makes every type of laptop you can imagine. The company designs and customizes products and services to end-user requirements, and offers an extensive selection of peripherals and software.
Those are some overview of those three computer manifacturers. Consequently, the different manifacturers have different price and performance characteristics. Let see their comparison of each through their aspects in computer organization and architure.
