Chipsets A chipset is a set of electronic components in an integrated circuit that manages the data flow between the processor, memory and peripherals. It is usually found in the motherboard of a computer. Chipsets are usually designed to work with a specific family of microprocessors. Because it controls communications between the processor and external devices, the chipset plays a crucial role in determining system performance. The chipset normally consists of two major microchips. These are known as the North bridge and the South Bridge. Developments in chip technologies have meant that chipset and CPU manufacturers are changing the way the chipset layout works, for example some CPU's come with a built in memory controller taking that job from the North Bridge, some chipsets have incorporated the north and south bridge in the same chip. The North Bridge Handles data for the graphics port whether that be AGP or PCI express and the main memory which includes the FSB (Front side bus). Although both chips are required for the PC to work the North Bridge handles most of the very important tasks such as the connection between the CPU and main memory bank. The South Bridge handles data from the PCI x1 slots and can also have integrated components such as Audio and/or onboard graphics. The North and South bridges will have different chip names even though they are very often paired with the same opposite bridge to come under the collective name of the chipset. Below is a diagram of the KT600 chipset from VIA technologies. This diagram shows how the components of your PC are connected to the chipset.

Motherboard Bus The motherboard bus is a set of wires that allows one part of the motherboard to connect and communicate with other parts of the motherboard, including the central processing unit (CPU). It also serves as an interface between the CPU and various external devices. The motherboard bus can be one of two types — internal and external. An internal bus serves as the communication highway of the motherboard. It links the different parts of the computer to the CPU and the main memory. Its primary task is to send data and instructions to the different parts within the motherboard, including the external bus. The external type of motherboard bus, which is also known as the expansion bus, serves as the interface for peripheral devices like hard disks, CD-ROM drives, and flash drives to get connected to the CPU. The shape of each interface is unique. This prevents plugging a device to a wrong port, which could cause damage to the device while being connected to the CPU.

Component Integration The motherboard includes some on-board components, meaning that they are integrated into its printed circuitry:
The chipset, a circuit which controls the majority of resources (including the bus interface with the processor, cache memory and random-access memory, expansion cards, etc.)
The CMOS clock and battery
The BIOS
The system bus and the expansion bus…...

...NT1110 Unit 4 Research Paper Student NT1110 Abstract Components and technology of today’s computer motherboards. This paper will give a brief description of chipsets, Motherboard bus’s, & Component Integration. NT1110 Unit 4 Research Paper The chipset on today’s computers is responsible for managing the flow of information between the CPU, Memory, & the Peripherals. Chipsets are usually deigned to work with a specific family of microprocessor such as Intel or AMD. Mother board Buses can be broken down into two different types, the first type is the internal bus. The internal bus is easily recognized by the gold lines of wire that run throughout the motherboard. The external buses are the slots filled with pins on the motherboard. Both types of bus are basically the lines of communication for the mother boar. There are six major types of external buses on a common motherboard, only a few of these are found on the mother board of a home PC, they are PCI, AGP, USB, & IDE. The external Buses connect to the Internal bus via the pins in there Appropriate slots, those pins transfer the information from the external buses to the internal bus and then to the final destination. The final topic of this paper is component Integration, component integration has eliminated the need for individual component hard ware and the heat they produce. The elimination of those two things has enabled the manufacturers to reduce the size of today’s computers enabling the......

Motherboard and Busses Nt1110

...Exploring the Motherboard and Busses Major components of the motherboard are the CPU, I/O ports, memory slots, expansion slots, mass storage ports, and busses. The CPU is the brain of the computer. It processes all of the computers functions. I/O ports connect input and output devices to the computer. Memory slots allow RAM to be inserted and to add additional memory. Expansion slots allow additional boards to be connected like, video, sound, or network cards. Mass storage ports connect storage devices like hard drives, CD-ROM, AND DVD-ROM. Busses are tiny electrical paths to connect each component of the computer together. If you upgrade the motherboard to give it performance improvements, the improvements are going to be limited because the motherboard doesn’t really improve the overall power of the system. You have to upgrade more than just the motherboard to improve speed and other things. The need for all the different busses on a motherboard is that each on has its own data width, cycle rate, and device management. The data width and cycle rate is used to determine bandwidth or how much data can be transmitted at one time. The device management indicates the maximum number of supported devices and the difficulty of configuring them. These busses can’t be replaced by a single bus because there is not bus fast enough to handle all these jobs at the same time and still be sufficient. With 64-bit busses available, 32-bit busses are still provided because......

Nt1110 Unit 5 Analysis 1: Pentium Flaw

...Unit 5 Analysis 1: Pentium Flaw The Intel Pentium microprocessor was introduced on March, 1993 that was hugely popular among consumers because of its cheap price and decent performance. Unfortunately, the early versions of these microprocessors had a flow within the floating point unit (also called a math coprocessor). This caused the Pentium's FPU to incorrectly divide certain floating-point numbers. Because only certain numbers divide incorrectly and Intel assumed that many users would never encounter the division error, the company decided to keep the issue quiet and fix the problem in updates to the chip. Thomas Nicely, a math professor at Lynchburg College, discovered the error however, and after sending his findings to Intel with no response, he posted his findings on the Internet, where others confirmed his theories. When Intel finally announced the bug, they originally said that they would only replace chips for users that require high-accuracy calculations, but when IBM publically refused to sell computers with faulty chips, Intel offered to replace all flawed Pentium processors. Because Intel chose to keep the flaw quiet, and because they originally refused to recall the product, they caused a great public outcry. Their mistakes also ended up costing them over $475 million and damaged their image. Intel now currently post all flaws and bugs that they find in their products in order to avoid another catastrophe like the Pentium Flaw. Other companies also take......

...Fredrick Donaldson Nov.5, 2014 NT1110 Unit 5 Assignment 1 Video Summary 3 CPUs In today’s market there are 2 main manufacturers of CPUs: Intel and AMD. There are also some smaller competitors that manufacture CPUs, but they tend to come and go. The way a CPU is organized varies, but here are the basics: The motherboard system bus carries information into and out of the CPU. When the system bus enters the CPU, it’s called a Front side bus. The Front side bus usually uses a 64-bit wide data path. On the side of the CPU you will find a controller. A controller manages the basic functions of the CPU, and controls communication between the motherboard and other components within the CPU. These other components includes one or more ALUs and internal cache. An ALU (Arithmetic Logic Unit), is responsible for solving complex calculations. Having multiple ALUs in a single processor is what gave the early Pentiums their multi-processing capabilities. Communication between the controllers and the ALU uses a 32-bit wide internal data bus. The bus system that supports communication between the cache, the ALU, and the controllers is referred to as the backside bus. The most important thing a person needs to know about a processor is the speed at which it processes information; (CPU speed). There are several ways to gauge CPU speeds. This may sound like an advantage, but oftentimes, these multiple ways are misleading. The speeds differ inside and outside the processor. Internally...

Unit 5 Short Answer Nt1110

...Daniel Thompson 10/17/14 Computer Structure and Logic The major compenents of a motherboard are the processor (CPU). This is the 'brain' of the computer and is the chip where all the computing is done. Next is the memory. This is where the computer stores information while it is working on it. Computer memory these days is typically installed on long, narrow boards called SIMMs, or "Single Inline Memory Modules" into matching sockets. Next is the "Chipset". This is a loosely coined term that may refer to one chip or a whole set of them. 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. Next are the expansion slots. These are connectors that allow you to attach additional "cards" on the computer, such as video cards, sound cards, modems, and add abilities to your computer that the motherboard doesn't provide. Some types of slots in use today called "PCI" or "PCI-E" slots. Next is the "IO" bank. This is a set of connectors that allows you to connect various devices to your computer, such as your keyboard, monitor, mouse, hard drives, flash drives, printers, and connect your computer to a network. Why an improvement would be limited is because the motherboard is not new, and is therefore limited to what it came with. It is best to get an entirely new system for a......

...Unit 6 Research Paper 1 Network Attached Storage ITT Tech Network attached storage (NAS) is basically a server that acts as hard drive that’s attached to a network. This connection to a network allows anyone who is also connected to the network the ability to access the hard drive. The NAS come in many sizes and different capabilities. The network connection that the NAS uses can be almost any that are available. The standard Ethernet connection is the most common connection by there are also systems that use a wireless connection or even a fiber optic connection for extremely fast transfer speeds. The storage of NAS systems can vary greatly. There are consumer models with a fixed amount of storage, and then the professional versions that have the capacity of many terabytes that can be upgraded when new drives become available. With the numerous amount of drives the chance of corrupted data and errors is always a possibility. With this possibility manufacturers have included the ability to arrange the drive into a RAID. The different RAID configurations allow users the protection from errors and data loss at the expense of storage space. NAS, unlike normal servers, do not require a keyboard, mouse, or monitor. They are usually managed from a remote terminal accessed via the NAS network connection. Some NAS systems use a web browser interface that uses the user’s web browser to interact with the NAS.

...Unit 10 Research Exercise Josue Tagle ITT Technical Institute NT-1110 1-What exactly is electrostatic discharge (ESD)? Electrostatic discharge (ESD) is the sudden flow of electricity between two electrically charged objects caused by contact, an electrical short or dielectric breakdown. A buildup of static electricity can be caused by tribocharging or by electrostatic induction. The ESD occurs when differently-charged objects are brought close together or when the dielectric between them breaks down, often creating a visible spark. 2-Perform the following research about the CompTIA’s Six Steps to troubleshooting, explain EACH step in DETAIL: Step 1: Identify the Problem In this first step you already know that there is a problem; now you have to identify exactly what it is. This means gathering information. You do this in a few ways: Step 2: Establish a Theory of Probable In step 2 you theorize as to what the most likely cause of the problem is. Start with the most probable or obvious cause. For example, if a computer won’t turn on, your theory of probable cause would be that the computer is not plugged in! This step differs from other troubleshooting processes in that you are not making a list of causes but instead are choosing one probable cause as a starting point. In this step you also need to define whether it is a hardware- or software-related issue. Step 3: Test the Theory to Determine In step 3 take your theory from step 2 and test it.......

...splitter for the cable. For example, if you only have 1 Universal Serial Bus (USB) port, yet you have a USB mouse and keyboard, then you can use a USB port expander to allow one port slot to become multiple ports and plug in the mouse and keyboard. Allowing multiple devices to be able to connect to a single port is a major advantage to port expanders. However, one of the biggest drawbacks is that the speed of that port is now divided throughout all the expansion ports, an example being a 3Gbps port expanded to accommodate 4 ports will now have to split that 3Gbps between all 4 ports and not 3Gbps per expansion slot. There are two types of port expanders: internal and external. An internal port expander will usually connect to the motherboard and have an expansion plate with multiple ports along the box of the computer. An external port expander will plug into an existing port (such as a USB) and will then have multiple connections off of the port expander. Port expanders are also very generic and will allow expansion on just about any computer. There are many ports available that come with port expansion hardware. Some examples are, but are not limited to, USB Port Expander Hardware, Microphone Port Expander Hardware, FireWire Port Expander Hardware, Serial Port Expander Hardware, SCSI Port Expander Hardware, Audio Port Expander Hardware, RS-422 Port Expander Hardware, SATA Port Expander Hardware, Ethernet Port Expander Hardware, Modbus Serial Port Hardware, SSD......

There are some minor competitions but don’t stay on the market for long. The system bus for the CPU is also known as the Front-side bus as it inserts the CPU and has a 64 bit data pass. In the CPU theirs a controller that controls communication between the motherboard and other components with the CPU. The ALU is responsible for performing complex calculations. Communications between the controllers and the ALU’s uses a 32 bit wide internal data bus. A processor is usually measured in GHz. A system Bus is usually measured in MHz and has limiting factors of speed. The multiplier is the ratio between processor and the System bus. The system bus speed x multiplier equals the processor speed. CPU manufactures have come up with different ways to make the CPU work faster. Two multi-processing requires multiple processors (In other words your system must be designed to support more than one CPU on a single motherboard). Dual Core Processors have been recently developed, that means incorporating multiple processors with multiple ALU’s inside a CPU. These ALU’s process their information individually. There’s two cache memory’s which are SRAM and DRAM. SRAM is also called Static RAM, it is faster and more expensive then DRAM, it holds memory without being refreshed and DRAM must be refreshed.
