Kernel Structure (Windows)
What is a kernel? Basically kernel is a computer program which manages input and output requests from the S/W, and then translates them into data processing instructions for the central process unit (CPU) and other electronic components of a PC.
Application
Kernel
CPU Memory Devices
Actually the kernel is the heart of an operating system. The task of this software is to run the programs and provide secure access to the computer’s hardware. If there are so many programs, and the resources are limited, this software called (kernel) also decides when and how long a program should run. It is also called scheduling. It might be very complex to access the hardware directly, since there’re so many different hardware designs for the same type of components. Usually kernels implement somehow level of hardware abstraction to hide the underlying complexity from applications and provide a uniform interface. This also helps application developers to develop …show more content…

And a computer system can be divided into 4 components: the operating system, the application programs, the uses, and the hardware. Without operating system we cannot use the computer.

Booting Process
To start the boot procedure, turn on the PC. This is known as a frosty boot. At the point when the PC is controlled on, it performs a Power On Self -Test (POST). Since the video connector has not yet been instated, mistakes that happen right now in the boot procedure are accounted for by a progression of capable of being heard tones, called beep codes.

After POST, the BIOS finds and peruses the design settings that are put away in the CMOS memory. The boot gadget need, is the request in which gadgets are checked to find the working framework. The boot gadget need is set in the BIOS and can be organized in any request. The BIOS boots the PC utilizing the first drive that contains a working

    Summary The following is an analysis of a proposed effort to improve the functionality, performance, and reliability of the computer described current configuration section, which is acting as an HTPC (Home Theatre PC). The budgetary allowance for this project is $500.00, but must prioritize a failed SATA hard drive containing the boot and system partitions. Secondary to replacements parts, considerable weight will be given to upgrades that would be compatible with a complete replacement within the next 24 months. Current Configuration Motherboard:

    I am going to explain the current methods and protocols we use in a LAN environment to provide a high level of redundancy, such as EtherChannel, FHRP (First Hop Redundancy Protocols) and STP (Spanning Tree protocols). I will briefly explain how the protocols work & then discusses the latest implementations of the protocol and the environment you would expect to see them working in. The STP is a protocol that prevents loops from occurring in a switched LAN environments when a device has multiple interconnected paths. The protocols works by sending BDPU messages across in the interconnected devices, detects the loop then removes it from the topology by shutting down the port.

    The research study includes two measurements, the Progressive Aerobic Cardiovascular Endurance Run (PACER) test and the Situational Motivation Scale (SIMS). The first focus of the clinical experience assignment was to observe the guidance counselor administer the SIMS questionnaire to students. Two fifth grade classes were observed; students in both classes participated in a second steps teambuilding activity prior to completing the SIMS questionnaire. One of the objectives for this clinical experience was to observe how the guidance counselor administered the questionnaire. After the teambuilding activity, students in both classes received detailed instructions from the counselor on how to complete the questionnaire.

    Network monitoring now is limited because of the number of servers it takes to deal with the large influx of router data. Router manufacturers have been attempting to combat this by adding counters to the routers that report on the number of data packets a router has processed during some time interval, but adding counters for every special task would be impractical and put more stress on servers since they would need thousands more to process the flood of data coming in. To combat this a system called Marple was created by researchers at MIT, Cisco Systems, and Barefoot Networks(Hardesty). Marple involves a programming language the allows network operators to specify a wide range of network-monitoring tasks and a small set of simple circuit elements that can execute any function specified in the language.
