VIDEO #3.01
Topics:
* Microsoft Operating Systems * Other Operating Systems
Terms:
* DOS – Disk Operating System is an acronym for several closely related operating systems that dominated the IBM PC compatible market between 1981 and 1995 * UNIX - is a family of multitasking, multiuser computer operating systems that derive from the original AT&T UNIX. * Command Line Interface - also known as command-line user interface, console user interface, and character user interface (CUI), is a means of interacting with a computer program where the user issues commands to the program in the form of successive lines of text (command lines).
Summary:
The video taught me that everything that was developed after series 9x of operating systems is built on the NT platform. Also the NT did not have a device manager or a hardware wizard as well as not supporting plug and play. I also learned that Linux was developed by a Finnish student named Linus Torvalds. This information is not really useful for me its old information that for me has no value unless I want to be a technology historian.

Topics:
* Partitioning * Creating Partitions * Create/Delete Partitions
Terms:
* Partition - In personal computers, a partition is a logical division of a hard disk created so that you can have different operating systems on the same hard disk or to create the appearance of having separate hard drives for file management, multiple users, or other purposes. * FAT - File Allocation Table is a computer file system architecture and a family of industry-standard file systems utilizing it. * NTFS - New Technology File System, The primary Windows file system, starting with Windows NT. NTFS is required to implement various security and administrative features in Windows.
Summary:
I learned in this video that there are two type of partitions. That being primary partition and extended and if you’re using the FAT file system you may only create 1 primary partition and 1 extended partition. If you’re using the NTFS file system you may create 4 primary partitions or 3 primary and 1 extended partitions. This video may be useful to eliminate answers in a test or may be useful for my electrical engineering job. The confusing thing of this video are the acronyms or abbreviations and memorizing them.

Topics:
* Active Partition * System Vs Boot
Terms:
* Boot Partition – A boot partition is a disk partition responsible for holding Windows system files when booting up Windows. * Active Partition - An active partition is a partition on a hard drive set as the bootable partition that contains the operating system. * Extended Partition - A partition is a logically independent section of a hard disk drive (HDD).
Summary:
I learned in this video that Active Partition is also called System Partition. The System Partition boots the computer and contains boot and system files. The Boot Partition boots loads Operating System. This information may be useful when trying to pass this class or maybe in the near future in my 6 figure yearly salary job. There was nothing really confusing for me in this video I think it could benefit me.

Topics:
* Low Level Formatting * High Level Formatting * Cluster
Terms:
* Sectors – In computer disk storage, a sector is a subdivision of a track on a magnetic disk or optical disc. * Master Boot Record – A master boot record MBR is a special type of boot sector at the very beginning of partitioned computer mass storage devices like fixed disks or removable drives intended for use with IBM PC-compatible systems and beyond. * FAT 16 – The FAT used for most older systems, used a 16-bit binary number to hold cluster numbers. A volume using FAT16 can hold a maximum of 65,526 clusters, FAT16 was used for hard disk volumes ranging in size from 16 MB to 2,048 MB. VFAT is a variant of FAT16. * FAT 32 - This strange term refers to the way Windows stores data on your hard drive. "FAT" stands for "File Allocation Table," which keeps track of all your files and helps the computer locate them on the disk. * NTFS - is a journaling file system that can recover from disk errors more readily than the earlier FAT32 file system. It also supports the Unicode character set and long file names (up to 255 characters).
Summary:
This video taught me about how low level formatting is done at the factory where the tracks and sectors are laid down on the hard drive. Each sector is 512 bytes per sector. The MBR contains the partition table and the master boot program. The video didn’t confuse me at all I understood every detail. The information that I acquired with this video is useful for repairing computers and learning how the components work.

Unit 5 Assignment 1: Video Summary 3 Cpus Nt1110

...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 the processor may work at 1, 2,......

The breadth and depth of data represented in this year’s DBIR is unprecedented. It combines the efforts of 19 global organizations: law enforcement agencies, national incident-reporting entities, research institutions, and a number of private security firms — all working to study and combat data breaches. Analysis With 47,000+ Security incidents analyzed, 621 confirmed data breaches studied, and 19 international contributors, Verizon has ample amounts of data to compile and use to better their network. This data can also be analyzed to see what types of people are making these breaches and what motives they may have for doing so. In the 2013 DBIR, 69% of breaches were spotted by an external party and 76% of the network intrusions were due too weak or stolen passwords. Some of the other factors that have been realized was that 75% of the attacks are opportunistic and 19% of attacks are some form of espionage. There is also much evidence that many of these breaches could be tied to organized crime and gathering financial information. On a very basic level, just looking at the history of organized crime, money has......

...Corey Young Monday The first part of this video was talking about the history of the operating systems. The Microsoft OS were DOS that had a GUI interface, after that you had NT, 9x, 2000, XP, Vista which in my opinion was terrible, server 2003 and 2008. There are also other OS that have been out Unix and Linux is what Macintosh are built from and then you also have Mac OS X. Video 3.02 was talking about installing new hard ware, creating partitions and formatting partitions, and installing OS systems. Before you install an OS system after installing a new hard drive you need to create and format a partition which will be an c partitions. There are two types of partitions which are primary and extended. You can only create one of each with the FAT file system. The NTFS you can create four primary partitions or three primaries and one extended. In creating partitions you need to know the order they are created and deleted. The orders to create partitions are first primary then extended and logical. To delete a partition you will simple reverse the order. Video 3.03 is about comparing active, system and boot partitions. After creating partitions you need to mark one active which usually contains the boot file so you can start up the OS. The system and the boot partitions are part of this system. The system partitions contain boot files which contains the operating system which boots up the OS. The boot partition contains system files which contain the OS files. So......

...Unit 6 Assignment 1: Cable Testers In almost every application in dealing with cable installations, cable testing is a must. Some methods of testing cables include testing for attenuation, continuity testers, DC Resistance, a wire mapper and cable length. In all cable types- copper or fiber, 10BASE-T or 100BASEFX, the standards are constantly being changed and developed into a new standard for all future technologies. When testing cable, you can guarantee that the users will be satisfied when all connections prove effective for not just uninterrupted transmission but correct bandwidths to support. A wire mapper is the most common tool. It simply provides a test of a standard Cat5 cable to ensure each individual wire not only carries a strong signal through the entire length of the route, but it proves if each wire ends up in the correct pin number on the opposite end to receive the transmission. It will give the technician an idea if a cable has a short, or if it is a crossover cable. It is also very useful with telephone connections. It should be a part of each cable installation kit. Another common tool is a continuity tester. It shows if there is a direct connection between two points. If there is a closed electrical pathway for the tester to detect, then the device will make a sound. This is useful not only to test for a short, but also to determine and identify which cable is which in a closet full of many cables. This is also a very important tool in any......

...Unit 5 Assignment 1: Video Summary NT1110 There are two major manufactures we use in today’s market which are Intel and AMD. 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. There are three types of RAM which are L1 cache, L2 cache, and L3......

Unit 6 Video Summary

...The video briefly discussed storage devices for computers. It covered internal storage devices, such as hard disk drives, and external storage, such as 8 ½ floppy disk drives. The video also described the different type of hard disk drive connectors which are as follows: * SATA * PATA * SCSI The video also had a rather detailed breakdown of how an internal hard disk drive works. During the explanation of how the drive works he used several terms that most people might not understand right away which he then defined for clarity. Following is a list of just a few of the terms that were used: * Platter – Disk located in the hard disk drive that data is stored on. * Track – a virtual ring on the platter used as a “groove” that data is written on for access purposes, similar to the grooves on a record. * Cylinder – vertical location of the platters within the hard disk drive. Combinations of platter number in the cylinder as well as track information are needed to retrieve data. * Latency – the delay before a transfer of data begins following an instruction for its transfer. Personally, I believe that the video was rather brief on a lot of the storage devices that were covered. The internals of the hard disk drive were covered very well; however, more time could have been put into describing the other forms of storage as well. Overall it was a very informative video, and I would recommend it to others needing to know more about storage devices....

Unit 6 Assignment 1: Video Summary 4 ( Raid )

...Alberto Legra 01/28/2016 Unit 6 Assignment 1: Video summary 4 (RAID) 1. URL Of video. https://www.youtube.com/watch?v=eE7Bfw9lFfs 2. Summary of video. In this video we learn the meaning of raid, what it does, and how to efficiently configure raid arrays. RAID stands for Redundant Array of Independent Disks. The three most common types of RAID; RAID 0, RAID 1, and RAID 10. Different raid configurations offer different advantages, like speed and reliability. RAID 0 is all about speed, by striping the data across 2 drives you can keep all of the capacity and double the read and write performance. However, RAID 0 provides no reliability, if one of your drives fail you will all of your data. RAID 1 in the other hand provides maximum reliability, but no performance increase. When both performance and reliability are needed, there is the option for a RAID 10 configuration. To configure a RAID 10 array, you need four drives, stripe the data on all four drives and mirror two against two. This RAID configuration allows you to get about double the performance and capacity of an individual drive, and you can lose up two drives without losing any data. 3. 3 topics mentioned in the video. * The meaning of RAID * Pros and cons of RAID configurations * How to configure RAID 4. 3 terms used in the video and their definitions. * Data striping: The technique of segmenting logically sequential data, such as a file. * RAID: Data storage virtualization......
