You can decide the topic (following the instruction) - Essay Example While there are no real guidelines on how to write a Letter to the Editor, a reading of the five letters (Bigbee; Little; Blumenthal; Allen and Huskey; Margelish) shows that such letters must contain an introduction (which connects to the article or issue that the writer is responding to), a body (which contains the writer’s position and the rationale behind it), and a summary or conclusion (which typically states the call to action). The introduction in this case is very important because it has to capture the audience’s attention and ensure that the topic being discussed is relevant. Letters to the Editor typically have strong introductions, which in turn dictate the tone style of the letter. For example in the first letter, Dean Bigbee said,†Every keystone argument leaves out the same major facts: Tar sands oil is not intended for United States consumption, but for shipping to the highest bidder†. Even if the readers did not read the February 7 column, th ey will know that this letter was opposing some assertions of the Joe Nacera article. One can see immediately that this letter will show objective evidences that will debunk some of the claims made in the Nacera article. Meanwhile, the second letter (Little) starts out with the following words: â€Å"Although Joe Nocera is probably right to lay most of the blame for the Keystone pipeline fiasco on our intractable political situation, President Obama is supposed to be the grown-up in the room†. From this introduction, one can already deduct that this letter will criticize the President Obama and that much of its claims will rely mainly on his personal opinion. One will notice, however, that while this second letter is written in the form of a criticism, it does not use abusive language. Because such letters are printed on a newspaper whose main audience are professionals, name calling will not help. Reader are more interested in the proof behind the claim, and while the letter is

Term - Research Paper Example It is firmly attached using screws through already drilled holes. Its front usually contains ports used to connect all the other internal components. In this case, one slot contains the central processing unit (CPU), while multiple slots allow for attachment of more memory modules. Other ports found on the motherboard allows for optical drive, floppy drive, and hard drive to connect through a ribbon cable. In addition, the computer case has some small wires that connect to the motherboard allowing for reset, power and LED lights to function. There is also a specially designed port on the motherboard through which power is supplied2. Part of the motherboard facing the back end of the case also has some ports. These ports are said to allow most external peripherals of the computer to connect to the monitor, keyboard, printer, mouse, phone lines, speakers and other external devices. Majority of motherboards also has FireWire and USB ports to enable compatible devices such as video camer as to connect to the computer when needed3. In fact, on the front side of the motherboard also exists quite a number of card slots. It is reported that these slots are where sound cards, video cards, and other expansion cards are connected to the motherboard. Functions of the motherboard System communication: It is through the motherboard that all forms of communication between the PC, its peripherals and other PCs plus the user go through4. Organization of devices: Is it has been elaborated everything within the computer are connected to the motherboard. In this way, its design dictates how the entire computer system is to be organized. Processor support: It is the motherboard socket that dictates the choice of processor that can be used in the system. Device control: The BIOS and chipset programs are usually built into the motherboard, which controls most data flow throughout the computer system. Support of peripherals: The motherboard components have a powerful function in determ ining the type of peripherals that a user can use in the PC of the computer. For instance, one cannot use AGP cards if the motherboard only has PCI slots. Upgradability: With the advancement in technology which see the emergence of new motherboards, it is a mater of fact that newer processors may experience compatibility problems with the hardware due to limitations of circuitry built-in to the board, which may not allow them to function. As a result, one may look for an upgrade at the manufacturer’s website or do upgrading5. System performance: The motherboard determines a great deal the performance of the computer since it dictates the type of memory, processors, system buses as well as hard disk interface speed that a computer system can have via BIOS settings or connectors. It is for this reason that in case a user upgrades after several years it is advisable to replace CPU, board and the memory6. 2. Central processing Unit (CPU) The CPU is arguably the brain of the compu ter, which is responsible for fetching, decoding, executing programs and performing mathematical and logical calculations7. In fact, without the CPU, the computer is just a nutshell. The CPU is made of numerous thin layers of transistors. The transistors are extremely tiny that blocks weak electricity when the charge is weak, but allows the same electricity to pass through when the power is strong enough. Since CPUs are small in size, they are sometimes referred to as microprocessors. Modern CPUs are
