Operating System Installation Course Learning Outcomes: After completing this course, students will be able to Identify and apply concepts of safe working conditions and procedures. Perform procedures to help protect equipment and data Identify and perform procedures on proper disposal of hazardous computer components and related materials Identify and use tools and software for effective and efficient computer system maintenance Perform occupational health and safety procedures in the workplace Top factors to consider when choosing an operating system When choosing an operating system, you must consider the primary purpose of your computer. This will guide on what to go for and what to avoid. Here are several factors to consider when installing an operating system. 1. Stability and robustness One of the most important parameters for a good operating system is its stability and robustness. You should choose an OS that will efficiently handle all its functions without crashing. With an unstable operating system, you will be required to reboot the system constantly. If you want to be sure of the best OS to go for, don't fall prey to the flashy advertisements. It is advisable to follow the developer's advice instead. In addition, you can get sound pieces of advice from people operating with a similar OS. 2. Management of memory Memory management is a crucial factor to look out for if you are wondering how to choose an operating system. A good OS should handle and manage primary memory and different processes between the main memory and the disk. An operating system that manages memory properly ensures accuracy, availability, and consistency of the data imported from the secondary memory to the main memory. 3. Memory leaks Some operating systems are known to suffer from memory leaks. Therefore, you should aim at choosing an operating system that does not suffer from memory leaks. A leak occurs when a particular process requests a chunk of memory for temporary storage but does not subsequently release it. The fragment of memory requested is made unavailable until the process is over. One process may have thousands of requests which could cause a considerable memory demand.

Operating System Installation 2 4. Memory sharing Good memory sharing capabilities is an essential factor to consider when choosing an OS. If you preload the modules and script while the server is starting up, data is shared between different computer processes. It is an essential factor as communication is faster through memory sharing than other message-passing models. Lack of a good memory sharing factor may impede other processes. A shared memory model may create various problems for the user and the computer. Some of these problems may include Synchronization of data Memory protection 5. Cost and support Everyone has a budget when it comes to buying things. In choosing an OS, cost and support are integral factors to consider. It is possible to get a cheaper or free OS that effectively serves the purpose too. There are several hardware components to consider when you want to purchase a machine. Therefore, if you can manage to spend less money on the operating system, you might have more to spend on faster and stronger hardware components. A. Hardware and software installation What is hardware and software installation? Hardware and software installation is the process of configuring hardware and software within a computer application or system. Hardware is any type of physical component that can be connected to or inserted into the device in order for it to function properly. Many pieces of hardware are enclosed in their own individual cases with external connections made by cables. The installation of hardware is the process of installing physical components into a computer or another electronic device. This also includes configuring motherboard jumpers or DIP switches, enabling and disabling integrated components, plugging in cables, etc. The installation of software is the process of putting data onto some kind of storage so that it can be accessed by other devices. Both are important elements required for the correct functioning of any given hardware or software product being used these days. They are also quite easy to perform. Let us take a look at both processes in more detail below. Are you a gamer? If yes, hardware and software installations are going to be a huge part of your life. Hardware installation is undertaken by a professional PC technician or even the owner of the hardware product themselves. Specialties include connecting cables between motherboard components as well as installing hard drives, optical drives, and other devices inside a computer case. Graphic cards, sound cards, and many other integrated elements have been installed manually for years now due to their size not being convenient for inclusion in cases. These days most people opt for external cases that are specifically designed for small form factor products made by Asus or MSI or any other manufacturer you prefer.

Operating System Installation 3 computers on the market here written by one of our members who his an expert in this field. Software installation on the other hand include the installation of operating systems like Windows, macOS etc and other application software. How to install hardware and software on your computer? Note: This guideline does not apply to all devices, as some may have very specific installation instructions. Before you install any hardware or software, it is important that you turn off your computer and restart it in order for the changes to take effect. You should also save all of your work before starting the process just in case something goes wrong during installation and your device becomes entirely unusable. If you are unsure about how to turn off your computer. Once you have turned off your computer and restarted it, follow these guidelines after reading through all documentation provided with the device: 1) Connect the external connections – For example, a printer will require an Ethernet cable connected to one port on your router and then one of the device’s ports connected to the other port on that router. All printers require additional power, so you will need an adapter that can supply enough for your device. Some also have software installed on your computer during installation which makes this process go much faster and more smoothly than it would otherwise 2) Install any required software – This is usually available on a disc or on the website through which you ordered it. Most new devices come with detailed instructions on how to install any required programs or extra drivers, but if using a program on CD, be sure to check for any special instructions prior to running the program. For example, some may ask you to connect an external device before they run in order for updates to work properly 3) Connect the hardware and turn on your computer – If you ordered extra cables, install them in the appropriate ports for best performance; if you ordered an external device such as a printer, plug it into the wall and then connect it to your computer. Then turn on your computer and go through any necessary installation windows in order to complete this process 4) Complete required steps or follow prompts to finalize software or drivers installation 5) Reboot your computer – Sometimes hardware or software installations require that you restart your computer before they can take full effect. If so, do so at this time. In The information, image/s, text or contents used in this learning module do not belong to me. This learning module is intended for educational purposes only.  CS414 - Operating System Module IV. Operating System Installation 4 some cases, you may have to reboot two times before everything is working properly, but usually not more than that 6) Troubleshoot – Some of the hardware or software installations may not be successful the first time. When this happens, you will need to go back and try again. If it is still unsuccessful after two tries, check your computer’s documentation for help troubleshooting issues with specific applications. Hardware installation checklist Below is a detailed checklist for installing new hardware on your computer. It is a good idea to check these items before you begin any installation just to ensure that you have all the necessary software and accessories. 1. Install driver(s) included with the hardware 2. Install latest drivers from manufacturer’s site 3. Power down the computer 4. Unplug the power, phone/network cables from the back of the computer 5. Ensure the case is open 6. Remove memory modules 7. Remove the battery 8. Slide out the hard drive 9. Plug in AC adapter 10. Attach AC adapter 11. Replace the main cover 12. Verify AC voltage at the wall socket 13. Reconnect network cable 14. Turn on the computer Software installation checklist Here are some important points you should watch out for when installing software onto your computer: Check whether you’re using the trial version of your OS. If so, try to activate it before proceeding with the installation process Download only from trusted sources or offline installation programs Disable all antivirus programs beforehand if possible, since they might interfere with the setup process Enable administrator access on your OS after downloading and before starting the installation The information, image/s, text or contents used in this learning module do not belong to me.

Hardware and Software Maintenance General Computer Cleaning Step 1: Always shut down, power off the system before carrying out any computer maintenance. Step 2: Never sprays any liquid onto any computer component. Spray or pour the liquid on a lint – free cloth and wipe the PC with the cloth. Avoid product with certain cellulose which will leave streaks on your computer equipment. The use of paper towels or an old rag to clean delicate surfaces of a computer should be discouraged because paper products contain cellulose which can scratch delicate surfaces of your hardware. Step 3: Use vacuum cleaner to remove dirt, dust, food and hair from keyboards.it is advisable to wear an anti – static wrist strip to reduce the transfer of static electricity from the body to the computer. Step 4: Do not apply cleaning solution including water directly to computer components. Step 5: Do not use your breath to blow the dust off the components because your breath contains moisture and the components are not built to be rust- proof. Step 6: Sometimes, it is necessary to replace fans or physically wipe some computer components. Step 7: Do not use anything wet or damp inside the computer case. Step 8: Do not let any component or circuit board inside the computer case get wet or damp. Step 9: Do not attempt to clean the motherboard with a cloth as it may damage the electrical components. Use a slightly moist cloth to wipe off dust and grime inside the computer case. Step 10: Do not allow any drink around the machinery. D. Software Maintenance The maintenance of programs inside the computer system such as virus, a spyware removal, back up software and a registry removal, cleaner. Every PC should be installed with an anti virus, a spyware removal application back up and a registry cleanser. Some helpful Tips Always scan your system once a week. The hardware should also be defragmented at least once a month. Delete all temporary files and cookies at regular interval.

Operating System Installation 6 TYPES OF SOFTWARE MAINTENANCE A. Corrective Maintenance B. Perfective Maintenance C. Adaptive Maintenance D. Preventive maintenance A. Corrective Maintenance This type of maintenance involves developing and deploying solution to problems that occur during usage of a software program. For instance, when an error message comes up on the screen or program is hanging or freezing or crashing, this implies that corrective software maintenance is needed. A computer programmer is employed to work on a more permanent solution to the problems. B. Perfective Maintenance This is a measure taken by computer programmer to upgrade the way a software programs function or how fast it processes, requests, develop software menu layouts and command interface so as to ensure that the program has zero tolerance for flaws. C. Adaptive Maintenance It takes care of the changes that occur in software development. For instance, if there is a change in processors speed, thus change will invariably affect how the software performs on a single computer software interfaces with other software programs. So changes in one program necessitates changes in other programs. D. Preventive Maintenance This is a situation whereby computer programmers try to prevent problems with software programs before they occur. They seek to prevent corrective maintenance as well as anticipating adaptive maintenance needs before users encounter problems. This is done by test running their programs to ensure that the software can handle high data loads and other stressful operation without difficulties. Computer programmers also ensure compatibility by testing the software with other programs users that are likely to use their software. Preventive Maintenance Activities Include The Following: Installing anti virus protection software and update Install firewall on your computer Keep computer registry up to date. Make sure your operating system is up to date The information, image/s, text or contents used in this learning module do not belong to me. This learning module is intended for educational purposes only.  CS414 - Operating System Module IV. Operating System Installation 7 Delete cookies Benefits of Software Maintenance 1. It promotes fully functional and highly reliable computer. 2. If preventive maintenance operations are carried out regularly, a PC will never run slowly or have programs that changes or freezes the computer. 3. When programs like CC cleaners or disk cleanser is used to clean up your hard drive , and also run Defraggler CD disk. Defragment process pack your files that are scattered across your hard drive into configures cluster ( Disk Defragmenter), allowing the file system to locate them easily. 4. When a PC is protected and maintained by S/W clean up programs, the hrd drive will not be slow and fragmentation will hardly occur. 5. Registry cleaning. 6. Problems due to lack of maintenance are reduced. Routine Computer Maintenance Routine Computer Maintenance consists of tasks performed on computer daily, weekly or monthly in order to keep the computer running efficiently for a long time. 1. Disk cleaning should be done weekly to get rid of “trash”. 2. Defragmentation- Run defrag which is located in terms tools to pull those fragments into one location. 3. Always update your system 4. Back up with external hard drive and back-up software. 5. Physical maintenance, i.e., regular physical cleaning of the hardware components should be observed. 6. Internet Security: Always run full updated antivirus program when using the internet and also perform full system scan with your anti virus program. It is ideal to run a firewall to block potential threats. 7. Patches and updates: They are regularly released by software companies to tackle security problems found in the programs. System administrators and network technicians should regularly download and apply these updates to ensure that their computers and their networks are protected from hackers, viruses and network intrusions. 8. Apply repair functions. Computer Maintenance Tips 1. Never turn your computer off with the power switch on until window has shut down. 2. Get a UPS ( Uninterrupted Power Supply) for your computer. The information, image/s, text or contents used in this learning module do not belong to me. This learning module is intended for educational purposes only.  CS414 - Operating System Module IV. Operating System Installation 8 3. Back up your data to external hard drives, DVD/ CD Roms, USB/ drives, memory card etc. 4. Run scan disk and defragment at least once in a month. 5. Never unplug peripheral from the computer when it is on. 6. Ensure that you have 300 mbs or 500-600 mbs of free space on your C Drive for window XP, Vista, or Window 7. 7. Do not allow a lot of programs to load up when you start your computer. 8. Use anti-virus checker regularly. 9. Use a firewall program for a high speed internet connection. 10. Keep track of the software disk you receive with your computer and new peripheral. 11. Make sure window update is set. C. Checking system requirement The system requirements or software requirements is a listing of what software programs or hardware devices are required to operate the program or game properly. System requirements are printed on their packaging, as shown in the image of the Windows 7 system requirements, or are found on the Internet. Example of system requirements Below is an example of the Windows 7 system requirements, with sections of the system requirements linked to the related definitions. 1 GHz processor or faster 32-bit (x86) or 64-bit (x64). 1 GB of RAM for 32-bit or 2 GB of RAM for 64-bit. 16 GB of hard drive space for 32-bit or 20 GB for 64-bit. DirectX 9 graphics device with WDDM 1.0 or higher. What if my computer doesn't meet the system requirements? If your computer does not meet the minimum system requirements, the program you are attempting to install will not run and may not even install. If your computer meets the minimum requirements but does not meet the suggested requirements, the program is going to work, but it may be slow. In some situations, you can upgrade your computer to help meet the requirements. For example, upgrading RAM, bigger hard drive, or a better video card can all help a computer meet the system requirements. Your computer may also support upgrading the processor, but in many cases, it requires that a new motherboard be installed. If the processor does not meet the requirements, we recommend considering getting a new computer. D. Occupational Health and Safety Policies Refers to the legislation, policies, procedures, and activities that aim to protect the health, safety, and welfare of all people at the workplace. An OHS Policy is simply a method of stating how you, your employees, contractors and visitors are expected to behave when they are on Company property or performing The information, image/s, text or contents used in this learning module do not belong to me. This learning module is intended for educational purposes only.  CS414 - Operating System Module IV. Operating System Installation 9 Company related activities. As an employer or responsible contractor, you are required by law to provide a ‘safe system of work’. Here is the list of the 12 Occupational Health and Safety Policies. 1. Do not work alone so that there’s someone who can take care of you in case of an emergency. 2. Always power off the computer and unplug the computer before working on it. 3. Take away any liquid near your working area to avoid getting electrocuted or accidentally damaging computer parts. 4. Be careful with tools that may cause a short circuit. 5. Always ground or discharge yourself before touching any part of the computer. 6. Do not use excessive force if things don’t quite slip into place. 7. Clean the area before and after using it to maintain sanitation and prevent accidents. 8. Hold the components on the edges and do not touch the Integrated Circuit (IC) parts. 9. Always wear personal protective equipment (PPE) in accordance with the organization’s OHS procedures and practices. 10. Make sure that the pins are properly aligned when connecting a cable connector. 11. Contingency measures during workplace accidents, fire, and other emergencies are recognized. 12. Use a brush, compressed air, or blower in cleaning the computer system. Fire Safety Follow fire safety guidelines to protect lives, structures, and equipment. To avoid an electrical shock and to prevent damage to the computer, turn off and unplug the computer before beginning a repair. Fire can spread rapidly and be very costly. Proper use of a fire extinguisher can prevent a small fire from getting out of control. When working with computer components, be aware of the possibility of an accidental fire and know how to react. Be alert for odors emitting from computers and electronic devices. When electronic components overheat or short out, they emit a burning odor. If there is a fire, follow these safety procedures: Never fight a fire that is out of control or not contained. Always have a planned fire escape route before beginning any work. Get out of the building quickly. Contact emergency services for help. Locate and read the instructions on the fire extinguishers in your workplace before you have to use them. Be familiar with the types of fire extinguishers used in your country or region. Each type of fire extinguisher has specific chemicals to fight different types of fires: The information, image/s, text or contents used in this learning module do not belong to me.

Use the memory aid P-A-S-S to remember the basic rules of fire extinguisher operation: P - Pull the pin. A - Aim at the base of the fire, not at the flames. S - Squeeze the lever. S - Sweep the nozzle from side to side. Procedures to Protect the Environment What is a Material Safety Data Sheet (MSDS)? A Material Safety Data Sheet (MSDS) is a document that contains information on the potential hazards (health, fire, reactivity and environmental) and how to work safely with the chemical product. It is an essential starting point for the development of a complete health and safety program. It also contains information on the use, storage, handling and emergency procedures all related to the hazards of the material. The MSDS contains much more information about the material than the label. MSDSs are prepared by the supplier or manufacturer of the material. It is intended to tell what the hazards of the product are, how to use the product safely, what to expect if the recommendations are not followed, what to do if accidents occur, how to recognize symptoms of overexposure, and what to do if such incidents occur. What information is on the MSDS? There are nine (9) categories of information that must be present on an MSDS in Canada. These categories are specified in the Controlled Products Regulations and include: 1. Product Information: product identifier (name), manufacturer and suppliers names, addresses, and emergency phone numbers 2. Hazardous Ingredients 3. Physical Data 4. Fire or Explosion Hazard Data 5. Reactivity Data: information on the chemical instability of a product and the substances it may react with 6. Toxicological Properties: health effects 7. Preventive Measures 8. First Aid Measures 9. Preparation Information: who is responsible for preparation and date of preparation of MSDS The information, image/s, text or contents used in this learning module do not belong to me.

Operating System Installation 11 The Controlled Products Regulations prescribes what information must be present in more detail. Computer component proper disposal The proper disposal or recycling of hazardous computer components is a global issue. Make sure to follow regulations that govern how to dispose specific items. Organizations that violate these regulations can be fined or face expensive legal battles. Batteries Batteries often contain rare earth metals that can be harmful to the environment. Batteries from portable computer systems can contain lead, cadmium, lithium, alkaline manganese, and mercury. These metals do not decay and remain in the environment for many years. Mercury is commonly used in the manufacturing of batteries and is extremely toxic and harmful to humans. Recycling batteries should be a standard practice for a technician. All batteries, including lithium-ion, nickel-cadmium, nickel-metal hydride, and lead-acid, are subject to disposal procedures that comply with local environmental regulations. Monitors Monitors contain glass, metal, plastics, lead, barium, and rare earth metals. According to the U.S. Environmental Protection Agency (EPA), monitors can contain approximately 4 pounds (1.8 kg) of lead. Monitors must be disposed of in compliance with environmental regulations. Handle CRT monitors with care. Extremely high voltage can be stored in CRT monitors, even after being disconnected from a power source. Toner Kits, Cartridges, and Developers Used printer toner kits and printer cartridges must be disposed of properly or recycled. Some toner cartridge suppliers and manufacturers take empty cartridges for refilling. Some companies specialize in refilling empty cartridges. Kits to refill inkjet printer cartridges are available but are not recommended, because the ink might leak into the printer, causing irreparable damage. Using refilled inkjet cartridges might also void the inkjet printer warranty. The information, image/s, text or contents used in this learning module do not belong to me.

Installing the operating system How to install an operating system The steps for installing an operating system, like Linux or Microsoft Windows, depending on the operating system version you are installing. Each version has different steps, requirements, and options that are unique to that operating system. Also, each operating system has different requirements for your computer to be able to run correctly. On this page, you'll find general steps and guidelines for installing an operating system on the hard disk drive of your computer. Purchase the operating system First, you need to purchase the operating system that you want to install on the computer. The best place to purchase the operating system from is a retail store, like Best Buy, or through an online store, like Amazon or Newegg. The operating system may come on multiple CD or DVD discs, or it may even come on a USB flash drive. Downloading a copy of the operating system is usually the most convenient way to obtain it. However, be sure you obtain the operating system from the publisher, like Microsoft. Downloading it from another source may result in an unusable or illegal copy of the software. Install the operating system To install the computer's operating system using a CD or DVD, you need to configure your computer to boot from the CD/DVD drive. You can change the boot sequence in your BIOS setup, and setting the CD/DVD drive to be the first boot device. Some computers may also allow you to access the boot sequence directly at computer start up, without entering the BIOS, by pressing a specific key on the keyboard. The key to press differs for each computer, but is often the Delete key or one of the function keys. If the operating system software came on a USB flash drive, you need to configure the computer to boot to a USB device as the first boot device. Once the computer is configured to boot to the proper device, the computer should load the operating system installation program and guide you through the install process. You will be asked questions along the way for configuration of basic settings, like date and time, user account name, and if you want to enable automatic operating system The information, image/s, text or contents used in this learning module do not belong to me.
