...NT1110: Module 6 Troubleshooting and Networks Final Exam Preparation Recap MODULE 1 Operating Systems There are three main operating systems in use today: Linux: Linux is an open source program available for free. “Open source” means that anyone who has the knowledge can improve the code, add functionality to the code, and modify the code to make it better. The only requirement is that you cannot sell it—you must give away your version for free. Linux is a subset of UNIX and is used more as a server OS than as a client. MAC: MAC has been a favourite of a select group, primarily those creating graphical arts, images, and video. In recent years, the MAC OS has become compatible with Intel processors. This has made the MAC computer system compatible with industry standard software, while the hardware has remained proprietary. The MAC OS commands approximately 8 percent to 15 percent of the OS market, while Linux has around 2 percent. Windows: Windows has approximately 82 percent to 90 percent of the market share. Windows XP is becoming the legacy version of the Windows OS, although it holds about 38 percent of the market share. Windows Vista did not fair too well on its release and now occupies only about 13 percent of the market share, while Windows 7 claims 30 percent of the market share. 1 NT1110: Module 6 Troubleshooting and Networks Final Exam Preparation Recap MODULE 2 Input and Output Devices I/O ports are primarily located on the back of...

...represents the logical foundation of the computer. Everything that makes a computer must be attached to the motherboard. Answer the following questions: 1. What are the major components of the motherboard? Provide a brief description of each component. 1. Processor (CPU): The processor is the brain of the computer and is the chip where all the computing is done. 2. Memory: This is where the computer stores information while it is working on it. 3. Chipset: The chipset is a link between the processor and the outside world, and handles things like controlling the hard drives, the USB ports, the keyboard and mouse, generates the sounds the computer makes, and sometimes even creates the pictures you see on the screen. 4. Expansion Slots: Expansion slots are connectors that allow you to attach additional cards on the computer, such as video cards, sound cards, modems, and add abilities to the computer that the motherboard doesn’t provide. 5. I/O (Inputs/ Outputs): These are a set of connectors that allows you to connect various devices to the computer, such as the keyboard, monitor, mouse, hard drives, flash drives, printers, and connect the computer to a network. 2. Upgrading only the motherboard will give some performance improvement to a computer system. Why? Upgrading the motherboard will definitely give performance improvement to any computer system. The motherboard itself comes with the many components that power the computer and give...

...Jasmin Kenjar NT1110 MODULE 3 SHORT ANSWER 3.1 The major components of the motherboard are the system bus and the I/O bus, the chipset, the form factors (intergrated I/O ports and memory slots), expansion slots, and memory storage interfaces. (1) The system bus controls the signals for data, power, control and addresses. (2) The I/O bus connects the storage devices to the system bus. (3) The chipset incorporates all the controllers on the motherboard. (4) The form factor is the layout of the computer’s motherboard.Intergrated I/O ports allows us to connect input/output devices such as keyboards. Memory slots contain the memory module which the system can’t function without. (5) Expansion slots: a. A PCI slot is used for many types of add on cards b. AGP is used for high speed video graphics. c. PCIe sends information faster than the PCI and AGP. d. AMR: Enables motherboard designers to place analog modem and audio connectors and the codec chip used to translate between analog and digital signals on a smaller riser card. e. CNR: A longer design that can support up to 6 channel audio, S/PDIF digital audio, and home networking functions. (6) The attachment point for mass storage devices is a mass storage interface. If you upgrade the motherboard you will only get some performance improvement to a computer system because the computer depends on more than the motherboard. Every bus in the motherboard has a specific function. These buses cannot be replaced with just...

...NT1110 Mr. Khan Nicole Snyder Kat Genovesio STORAGE DEVICES Installing a new hard drive requires creating partitions, formatting partitions before installing operating system. Hard drives are comprised of platters, have read/write heads on top and bottom for each platter. Since they are coated with magnetic film, which contain the bits, they should never be exposed to a magnet as it may result in data loss. Hard drives and gilded to protect their data, but floppy disks are not. The BIOS can be flashed to upgrade the system. The hard drives can attach to the motherboard using different interfaces, such as PATA, SATA, SCSI, USB, and FireWire; PATA (Parallel ATA) interface is most commonly used and is sometimes referred to as IDE or EIDE. The IDE (PATA) cable has 2 connector which are master and slave, the motherboard supports 2 cables which are primary and secondary. The motherboard can support 4 devices total (primary master/slave and secondary master/slave). The motherboard connector may be color coded, blue is primary and black is second. The cable connectors may also be color coded, blue goes into motherboard (regardless of primary or secondary), black goes to first device and grey is second device. The jumpers on the drive determine the master/slave designation. The hard drive should be installed as master on the primary cable, other devices should be second to improve performance. The cords have improved from 40 pin/40 wires to 40 pin/80 wires (the extra wires are...

...Motherboards Marc Burzynski Unit 4 Assignment 1 NT1110 07/20/2013 Video 1.04 Summary This video talked about the differences in the different form factors motherboards as well as the similarities. It explains for those of us who prefer to build our own systems that we should select our motherboard before buying the tower and after we have selected the CPU. It also explains about the different types of connectors found on motherboards. List Of Topics, Terms And Definitions * Motherboard – The most important consideration, the size and shape is determined by form factor * ATX Form Factor – Replaced the AT form factor, ATX is smaller, easier to work on, better organization, has support for a wide variety of I/O devices, usually has is the P1 20 pin or 24 pin power connector, on the older ATX form factor motherboards were connected via the PS/2 connector at the back of the case, the newer ATX form factor motherboards connected keyboard and mouse via a USB, usually has between two and four DIMM slots, has either PCI E Oren AGP slot but not both, usually has 2 40 pin IDE slots, and usually 1 to 2 serial ATA slots. The ATA form factor was the first to introduce the soft power switch on the front of the computer; the soft power switch does not immediately cut power but instead allows the computer to go through the normal shutdown procedure. There is however a power switch on the back of the computer, flipping the switch immediately kills power. Another important...
