Operating System Tools

Question: Explain Operating System Tools. Answer: Operating system tools. Operating system tools can be software programs that are part of the operating system or that are purchased and added separately. Most included programs are those for controlling and setting up the printers and any other plug and play devices. These programs help alter the output display, program addition as well as hardware, it also help us to manage the disk by performing operations like formatting, clean up, and disk optimization. How to install, configure, and personalize an operating system. Before any installation we are supposed to the operating system is prepared to install by collecting the information about the hardware to necessitate configuration establishment in decision making during process of installing. These are the guidelines that need to be well defined before starting the process. Hardware Compatibility:-we have to review all the hardware and ensure that it conforms to the requirements that the operating system needs to handle. Disk space:-sufficient space is required for the installation process so that we do not halt halfway as we are installing due to space, in a case where the system halts the operating system gets corrupted and forces us to start over. The free memory should be at least 10GB for good functioning. Disk Partitions:-we need to break down the hard disk space so that we allocate one partition to keep the OS and the others we assign a name so that we will be saving corresponding documents there. File system: - System files needs to NTFS configured because it allows for security configuration. A system running in NTFS is much more secure as considered to other formats. Any previous OS should be cleaned in all hard disks partition before installing the Operating System. Installation Method With installation method we have to choose if its either going to be installed from boot disks like CD-ROM and DVD, using a USB drive or over the network using PXE Types of Installation Creating image:-requires the installer to come up with a windows system that is bootable that is that make sector copies of everything on the computer. Unattended Installation:-this an installation where one create an .xml document with answers to all the processes, these .xml is customized so that it will run on its own. Upgrade:-these is an installation which begins in presence of previous installations and on identifying it makes an upgrade to the existing to a much later version without altering files nor applications present. Clean Install:-these is where we erase everything in the computer and the install the Operating System to the computer a fresh, it will set all configurations and personalized settings to default. Repair Installation:-is one that usually takes place in case of OS corruption, an attack from a Trojan or worm that has caused the operating system to malfunction. Multiboot:-these allows us to dual boot Operating system, we can install two or more Operating system and all are able to work as required. Installation Process Am going to demonstrate the installation process Using a bootable DVD or CD-ROM, in these case we start the installation from a bootable CD:- Insert the bootable DVD in the disk drive One need to restart the machine and go into bios and set the computer to boot from the DVD, when set up loads you one need to press any key to start the booting process from the disk. We then follow the set-up instruction on the screen. After following the procedure its now time to configure the disk partitions for installation Configuring Disk Partitions and installing Dynamic partition: - is a partition that does not allow any addition of new drive in addition to spanning of data from the basic partition into the newly installed drive. Basic:-this is either a Disk Operating System or windows installed on it.it can bear primary and logical partitions with inclusion of logical drive. Primary:-these partition is the one the system can boot from, it allows performance of Multi-boot capability where one partition is designed as active partition and launches once the computer is powered on. Extended:-these partition comes into use when we need more than four partitions in a disk, with extended partitions we cannot boot from them Logical:-these are partitions created inside an extended partition and does not allow an operating system to boot from it. Installation Formatting takes place after the portion has been created through use of NTFS which is more secure Select the disk partition that the windows will install into After the formatting process, set the computer name and administrator password and you are now well set to customize and personalize the operating system into a way you need. Operating system and process monitoring tools. Monitoring performance of an operating system is important because it allows us to debug processes and systems, to manage efficiently and effectively the system resources, making system decisions and examining the system. The tools are primarily divided into two categories:- Real Time -These are tools for measuring the system current state which helps provides performance information about a system Long-based monitoring helps to keep information about the performance in processing information and analysis (Operating System Tools, n.d.) Monitoring Tools Operating systems monitor their resources, in a computing environment processes are the key resources being monitored and is done at every process level. The information are collected as the operating system is running so as to check on effective memory management, scheduling, multiprogramming and other decisions Performance monitoring is useful while developing and refining systems as well as provide day to day operation. Monitoring helps us to forecast on the performance of the system and have a long term solution to a defect in case the operating system malfunctions. The tools used in monitoring performance include:- Real Time Performance Tools-displays the current state of the system. Task manager:-is a tool for monitoring processes on windows OS it helps us analyze the performance of the running apps and here we can disable those applications that are not in use.(Installing Operating System, n.d.)
