http://faq.cpals.com/buycomputer.html • The computer power supply just feeds power to the computer • This site gives a bunch of information • helps you find the better of the item like the case
motherboard • Motherboards have a lot of stuff on it and holds most of the stuff in your computer • Most things plug it
Motherboard parts • microprocessor=computer brain-sends the commands • Memory=RAM-computer storage • Drive controllers=multiple different hard drives-there are few different kinds – mainly hard disk drives, CD-ROM drives, and floppy drives
Drives • Hard disk-a permanent storage for files • CD-ROM-files can be stored here and read • Floppy-stores memory as well-floppys are starting to disappear because there out of date
other physical parts of a computer • Monitor-used for viewing the data or what the computer is currently doing • Keyboard-enters written commands or information • Mouse-also sends commands- can be greatly upgraded
COMPUTER CASES BY:ALBERT AND DARRYLE
WHAT ARE COMPUTER CASES? • THERE ARE TWO STYLES, DESKTOP AND TOWER. • THE DESKTOP STYLE IS A RECTANGULAR BOX THAT SITS ON TOP OF THE DESK. • THE TOWER IS THE SAME LOOK BUT IS A BETTER WAY BECAUSE IT IS DESIGNED TO DISSIPATE HEAT.
TOWER SIZES • COMPUTER TOWERS COME IN ALL DIFFERENT TYPES SIZES TO MATCH THE PC. • THERE ARE THE MINI-TOWER WHICH IS THE SMALLEST, THEN THERE IS THE MID-TOWER WHICH IS THE STANDARD SIZE, THEN THE FULL TOWER WHICH IS THE LARGEST. • THE TOWER SIZES IS IMPORTANT BECAUSE THE BIGGER THE TOWER IS THE MORE MEMORY IT IS GOING TO HOLD.
DEFINITIONS • PIN- A PART OF A CONNECTOR THAT MAKES CONTACT WITH A SOCKET. • SOCKET-A PART OF A CONNECTOR RECIEVES THE PIN. • JACK-A PLACE WHERE A PLUG MAY PLUG INTO. • PLUG-THE PART THAT HAS CONTACT WITH THE JACK.
Inside the Computer and its Motherboard By Chyrial Camacho & Conner Mitchell
Inside a Computer Ok Before you even start to look in your computer you have to take safety precautions. There is a risk that there may be adischarge of electricity to the circuits in your computer due tothe static electricity that the human body contains. So payattention and be very carefully. Well anyways to open thecomputer case you will need to remove four to five screwsand slide the case forward on its slots and move it. Once you open the case you must lay it on its side then you look in it. When you look into your computer what you will see is theExpansion Card Slots, Power Supply, Power Connector,Floppy and Hard Drive Connectors, Enclosure around drivebays CD-ROM/ Hard drive Bay, Hard/ Floppy Drive Bay,Memory Sockets, Microprocessor, the Motherboard and awhole bunch of wires. In the computer, you will also see Cables between the hard, floppy and CD-ROM Bays. These cables are all connected to the motherboard. All the greycolored wires are the ones connected to the motherboard.The black, red and yellow colored ones are all connectedbetween the power supply. The multicolored wires are allconnected from the motherboard to the power supply.
What is a motherboard? For all of those people who are wondering what amotherboard is, well lets just say today is your lucky day. Amotherboard is basically the mother all the boards. Thereare two types of motherboards but the type that is mostcommonly suggested is the ATX because it is newer thanthe other type called the AT and also the most modernmicroprocessors run on ATX motherboards. Themotherboard holds the microprocessor, the memory, andseveral card slots. The card slots are what is used to putadditional cards on the computer such as video cards,sound cards, internal modems, and network cards. Whenyou talk about cards that are plugged into a PC you areusually talking about the expansion bus. The definition ofexpansion bus is a microprocessor extending its informationfurther to the outside world.
Inside the Computer and Motherboard By Chyrial Camacho and Connor Mitchell
What is a Computer? A Computer is a machine that manipulates data according to a set of instructions. Computers are able to conduct serious mind-blowing tasks/mathematical calculations, making it much more knowledgeable and capable than the human mind, which could just not handle such tasks. The first devices resembling computers date back to roughly 1940-45, even though the concepts of machines existed long before that. These machines didn’t exist back then because the technology required for the construction of such a futuristic machine did not exsist.It was primitive times. However, nowadays, computers are an abundant part of today’s society. For example, computers can be found in roughly 75% of United States homes (not including Puerto Rico and Guam). Some benefits of computers is that they are extremely versatile due to the ability to store and execute lists called programs. Some examples of this are: -Military jet and ship navigation/weapons computers (solutions) -Traffic management (synchronization of traffic lights) -Calculators (conducting mathematical calculations) First off, it is important to understand that the term computer first meant “any human that performed numerical calculations with the aid of mechanical calculating devices.” Programs are instructions for computers. The first computer was made in Germany in May 1941, operating by a binary (two digit) numeral system, and an electro-mechanical computing mechanism, called the Zuse Z3.It was program controlled by punched film stock, and it’s Turing was complete in 1998. You can install memory cells in a computer for data storage for later on, and programs stored on the memory disks for the computer to carry out sometime in the future. Programs are very important. It’s what the computer does. What’s the point if the computer doesn’t do anything, right? Normally, the instructions are very simple, being adding numbers, moving data, sending messages, etc. They are read by the computer from the memory(programs are what is stored here), and are generally carried out in the programs assigned order. Different Computers are made, and you can have different memory devices that need to be installed on the computer, some with more memory, some with less, depending on the manufacturers’ quality. More quality usually means a higher price for this product that you need to buy from any computer/computer product selling store. It also varies with all the other essential parts of the computer, such as sound cards, video cards, etc. The main part, or brain of the computer is the central processing unit, or cpu.It utilizes input devices, like keyboards, for the taking in of symbolic data, and output devices, like monitors and printers, for sending out the symbolic results. It is made up of internal memory, a processor, and arithmetic logic unit.
What is Motherboard? A mother board is one of the components that make up a computer. It is where the core components of your computer resides. It mounts the microprocessor, which is the brain of your computer. It also mounts the video, sound, networking cards, etc.Their quality, price, and availability varies from retail store to retail store. Motherboards have a form factor of AT or ATX.The memory may be SIMM or DIMM sockets. The expansion bus is card slots made into the frame of the motherboard for physical installation of the essential video, sound, and networking cards. Some include these already in the motherboard. The card slots are mostly PCI type card slots. This is a means of the microprocessor extending its communication ability further into the outside world(printing papers). There have been several types of expansion buses. Other motherboard items are small pin connectors used to connect the following controls to your motherboard: • Power supply switch • Reset switch • The “power on” indicator • Hard drive activity indicator • In the case speaker connector. If you have any sort of mechanical problems with your motherboard, you can refer to your motherboard manual for help, or contact a certified technician. You also need to refer to this manual for the process of constructing your motherboard, and PC. The Pc comes with a help manual, and you can get certified technicians to work on it if any problem should arise. And pc’s are complicated machines.
Microprocessors By: Ashlyn Rosa
What is a Microprocessor? • Definition: An integrated circuit that contains the entire central processing unit of a computer on a single chip. • The brain of a computer
What’s the best microprocessor? • E2v is the best • They make High Reliability Microprocessors • Other types are: Pentium, K6, PowerPC, Sparc, and many others • Make sure you get a motherboard that your microprocessor will work with

Computer Memory By: Nea Moi Spix and Kaleo Lum
Packaging • Memory chips are DIPs-Dual Inline Packages -black chips with pins on both sides • there are 2 main module types that memory comes packaged in today -SIMM and DIMM • SIMM- single inline memory module -may have DIPs on one or both sides and usually has 72 pins and sometimes 30pins • DIMM- double inline memory module -has 168 pins -synchronous dynamic access (SDRAM) is the memory type used • Installation of packages (SIMM & DIMM): -press socket on the motherboard -latch them in with a plastic latch on both sides and that’s it
DRAM Access • DRAM memory is used in things called cells • Each cell has a number of bits or bytes • The cells are arranged in a row, column scheme (like the background) • The row and then the column address is specified when DRAM is accessed
Types of DRAM • DRAM-dynamic random access memory -there are three commmon types of DRAM • FPM DRAM- Fast Page Mode. When the first memory access is done, the row or page of the memory is specified. Once this is don’t, FPO DRAM allows any other row of memory to be accessed without specifying the row number. This speeds up access time. • EDO DRAM-Extended Data Out. This works like the FPO DRAM but it holds the data valid even after strobe signals have gone inactive. This allows the microprocessor to request memory, and it does not need to wait for the memory to become valid. It can do other tasking, then come back later to get the data. • SDRAM-Synchronized DRAM inputs and outputs its data synchronized to clock that runs at some fraction of the microprocessor speed. SDRAM is the fastest of these three types of DRAM. There is a new SDRAM called DDR (Double Data Rate) SDRAM which allows data reads on both the rising and falling edge of the synchronized clock. • Other types- • RDRAM-developed by Rambus, Inc. SLDRAM-Synclink
Cache Memory • Cache memory is a special memory that is more expensive and faster than SDRAM memory • It would be not useful to use this memory for the entire system for reasons of expense, physical board and bus channel design requirements • Cache memory is between the microprocessor and RAM • It is used as a buffer to reduce the time of memory access • There are 2 levels to the memory known as L1 and L2 -L1:part of the microprocessor -L2: is outside of the mircroprocessor
Is The Bigfoot Networks Killer NIC Vaporware? I'm sure you've heard about it. I'm sure that you have seen the software rendered pictures. And I'm pretty sure you've seen people saying that the Killer NIC by Bigfoot Networks is nothing more than vaporware. I hate to admit it, but just weeks before their official launch all that we have seen floating around the web is this picture. Bigfoot Networks has been around since October 2004 and hasn't produced much of anything yet, so I can understand the doubt around the product. Just recently Bigfoot Networks has released a whitepaper and some performance numbers in a sneak peak document found on their website. Bigfoot Networks is still planning to launch their retail boxed Killer NIC cards in 1 to 2 weeks, but has yet to release any images of their card other than this render. Does that throw up the red flag? The above image looks pretty cool, but we all know that it isn't a 'real' network interface card! We contacted our friends down at Bigfoot Networks and told them they really needed to publish a real picture of the card to show that it's real. They informed Legit Reviews that the card is indeed real, but are still working on getting the intricately designed heat sinks shipped in to be installed for the retail cards. After a little begging we talked Bigfoot Networks into sending over some pictures of the card without the heat spreader installed. Behold the internets first real pictures of the Killer NIC!

Cheap monitors usually have… • A small screen size • A bigger dot pitch • A low pixel resolution
Expensive Monitors • Faster CPUs, more memory, bigger, better hard drives and flashy, speedy video cards. • If you were getting a more expensive monitor you should ask always about the dot pitch. A dot pitch is just the measurements in millimeters between the individuals pixels that make up the surface of the screen. • A more expensive monitor will have a .24 dot pitch to appear crisper and more detailed than a .27 dot pitch display. • Expensive monitors look a lot better and more hi tech then others that is one reason why people by expensive monitors.
