LCD monitors weigh less that CRT monitors C. LCD monitors are required by law due to their power saving settings D. LCD monitors offer more security for the individual computer user. PLEASE GO ON TO THE NEXT PAGE 5. After looking at numerous computer cases for his custom PC, Brett has decided on a case with a 600-watt power supply. Why should consumers and computer builders both be concerned about the wattage of a power supply. Each powered component of a computer system pulls from the power supply. If the supply does not have enough watts to supply power to all components then A. the system will no function correctly. B. C. D. 6. 7. 8. The wattage should be matched with the national power standards as in the United states all power supplies should be kept under 200 watts, while in Europe all power supplies must be under 300 watts. If a power supply has to much power then devices will not function correctly because they will receive to much power. The lower the wattage the better the power supply will perform with high end computer systems such as gaming PC’s or programming PC’s. While looking through the material included with his new computer, Matt discovered a page that contained a Motherboard location map. Which of the following would not generally be found on a Motherboard location map? A. CPU location B. DIMM slots C. PCI slots D. CPU heat sink Eddie was amazed at all of the options available concerning the CPU selection for his new PC. Which of the following statements is true concerning the CPU? A. CPU’S are interchangeable on a motherboard B. CPU’s only interact with the DIMM and PCI slots on a motherboard C. CPU’s must match up with the socket type on a motherboard D. CPU’s within the Pentium 2 family of processors use socket 7 on the motherboard for installation As Ken was taking a close look at the small writing on his motherboard he noticed some writing beside a plastic piece that read, “DIMM 1”. DIMM 1 could be best described as A. A port used to allow advanced graphic cards to be installed on the motherboard B. A module used for memory on a motherboard C. A port used to expand the processing power of the CPU D. A module used to install extra cards in a motherboard for expansion purposes. PLEASE GO ON TO THE NEXT PAGE 9. Mattie has disassembled her computer’s hard drive. She has located a large shiny disc that looks very similar to a CD. What component of a hard drive has Mattie located? A. Spindle B. Actuator C. Read/Write Head D. Platter Motherboard Quality: How to Find a Good Motherboard Motherboards can be confusing to shop for; they have lots of parts and all look about the same. How do you know you are getting a good motherboard? Here are a few things that you can check for a good sense of what you are getting. The Thing that Connects Everything The Motherboard is probably the easiest computer component to ignore when budgeting for your new computer build or when you are trying to upgrade. Yet as the component that connects everything together it is one of the most important components you have. Having a good quality motherboard is essential to your computer's speed and connectivity as well as the life of the computer. But most importantly, the identity of your PC is tied to your Motherboard--you don't need to get a new version of Windows until you get a new motherboard since Microsoft attaches your Windows serial key to the motherboard. This means you can keep upgrading your computer until you replace the motherboard; then it's like getting a new computer. But what do you look for in a motherboard? For the person without a ton of knowledge (What is a northbridge? How do I know a good chipset?) you can do a couple easy things to check your motherboard quality: 1) Price As simple as it seems, price is a decent enough indicator of motherboard quality. The retailers will always keep their new and better models more expensive. So I'd say spending a bit more money will help you out right away. But don't just rely on price; it's just a place to start. A decent price range for a motherboard as of this writing would be $150-$400 depending on your budget. 2) Reviews Again, this sounds simple but looking at the reviews for a motherboard will get you a better sense of quality and durability than pretty much anything else. Websites like Newegg, Tiger Direct, or Amazon all have good review systems with lots of users who will let you know if there are any major issues with the motherboard or whether it is high quality. Keep in mind that any computer component has a certain number of failures and problems. Just because there are a few people complaining their MB was DOA (dead on arrival) doesn't mean you can't get it. But if those DOA make up a disproportionate amount of the reviews (I'd say more than 5%) then I'd probably be wary. PLEASE GO ON TO THE NEXT PAGE 3) Components To get a sense of the beefiness (but not necessarily the quality or durability) of the board, take a look at its components. Here are things you want to note in the components 1. CPU Compatibility: Your MB will determine what processors you can use. Make sure it can use a good one and that you have space for future upgrades. 2. Memory Standard: Again, this is determined by your motherboard. The faster the speed the quicker your computer will run. At least get a motherboard with DDR3. Just keep in mind you'll have to spend more for your RAM but its totally worth it. 3. Number of Connections: How many SATA connectors are there? Is it enough for your needs? How many PCI slots are there? Is your video card going to fit? Also, how many connections are build into the external portion of the motherboard (USBs particularly)? Is this going to be enough? 4) Look up the Chipset If you really want to know more detailed info on the quality of the motherboard then you might want to look up reviews and features for different chipsets. There are two parts to the chipset of any motherboard, the northbridge and the southbridge. As people with the old XBox 360s know, the chipset can determine a lot about durability and quality (the old chipset is why 360s red ringed so much). But how do you know if a chipset is any good? The best way to do it is to just search for it and look for reviews. The great thing about the internet is that there are some people out there with the technical knowledge sufficient to give you a good sense of its quality 10.

What is the main idea of this passage? Motherboards are very expensive and should be purchased after the CPU is A. purchased. Motherboards can easily be transferred from one computer to another computer B. for only a small amount of cost. Motherboards work well in most computers but other computer systems need C. more advanced circuit boards that are called Fiberboard’s. Motherboards are devices with many different operations that flow through D. them and motherboards can make or break an entire computer system. 12. Who is the intended audience for this article? A. Software Engineers B. Motherboard Designers C. Custom PC Buyers D. CPU Developers PLEASE GO ON TO THE NEXT PAGE OPEN-RESPONSE QUESTION Read all parts of the open-response question before you begin. Write your answers to the openresponse question in the space provided on your Student Response Booklet. DO NOT WRITE ANY ANSWERS IN THIS TEST BOOKLET. The computer is made up of numerous parts and pieces that form a very impressive object. Technicians are needed to ensure that each computer works correctly on a daily basis and knowledge of each part must be understood so that he or she can fully grasp the full design spectrum of the Personal Computer. 13. A. Describe the steps one would take to install a new hard drive(with an IDE interface) inside a computer system that has just been put together B. Explain the components one would find inside of a computer’s hard drive.
