For most computers, room temperature should be between 60 to 85 degrees Fahrenheit (15.5 to 29.5 degrees Celsius) with a humidity level between 50 and 75 percent (to minimize any static buildup). While most offices are kept at this level during the day, check with your landlord to ensure when you leave at night that the heating, ventilation, and air-conditioning system does not rise above or fall below these levels.
Air quality is important because computers require air circulation to prevent overheating. There are two rules of thumb:
Electricity is a key factor in determining the longevity of your computer. It's akin to the oil, fuel, and coolant in your car's engine: whereas poor or dirty engine liquids will take their toll on your car and shorten its life, so-called "dirty" electricity (brownouts, surges, sags, spikes, and so on) will damage your computer, and your files, far more effectively than any virus.
There are four steps you can take to create good electrical conditions for your computer:
I recommend getting virus protection software that combines virus and spyware protection at a minimum; add the firewall option if you do not use an operating system with a built-in firewall. Critical updates are just that - software patches rated "critical" by the vendor; all other patches, enhancements, and updates can wait for the end of the year.
The electronic tune-up consists of the regular monthly maintenance plus a disk scan of your hard drives and a manual check of all software for updates. In Windows XP, utilize the Check Disk utility - check both boxes to fix file-system errors and scan for bad sectors.
For each application, such as Adobe Reader or Microsoft Office, check for updates using their built-in method or via the support or download section of their Web sites. Although you may not be required to do so, I recommend restarting your computer after each software package has been updated. This will allow the various bits of code to properly "register" with the computer and cause any error messages to be isolated to the last update you did (versus just "something").
The physical tune-up, while short (it takes five to ten minutes from start to finish), might seem intimidating at first. Don't let it scare you, though. There are only five simple steps: unplug, unplug, look, lift, and dust.
First, turn off and unplug your computer and your monitor. Next, unplug the rest of the cables from the computer case, including the network cable, the printer cable, and so on. Inspect the cabling for any broken or frayed bits. If you have a laptop, take out the battery. For desktop computers, unscrew the case (generally in the back) and lift it off (some computers, like Dell and HP, have flip cases that you open by pressing a plastic button).
Now, with the hose and bristle-sweep attachment of your vacuum, clean off the air vents on the outside of the computer case, the monitor, and the keyboard (and the docking station if you have a laptop). Then, gently vacuum out the dust from inside the case. This is not a detailed spring cleaning; go lightly and quickly (it should take you less than 30 seconds).
For recommendations, look on the Web at generalist IT and consulting professional societies like Independent Computer Consultants Association (ICCA), Society of Professional Consultants (SPC) or Institute of Management Consultants USA (IMC USA), as well as N-TEN or TechSoup.
If you want to try tackling the "health check" on your own or if you are uncertain about what to keep an eye on with different IT professionals and technology service firms, I recommend the following 10 items for the core health check.
Just as cars frequently display symptoms upon startup, so do computers. To the trained ear, a high-pitched whine or inconsistent grinding noise can quickly identify a failing monitor, fan, or hard drive. The cold-start (or "cold-boot") process starts up the computer from a completely powered-off state, skipping any welcome or other splash screens to look for error messages that may appear during startup and to listen for any warning beeps or other sounds.
Cars can be hooked up to automated diagnostic utilities to quickly see any issues, and so can computers. First, go online to a free antivirus or spyware scanner, such as those provided by Trend Micro. Next, go to a PC diagnostics site like PC Pitstop and run the free full tuneup. Print out the site's suggestions to consider later.
In Windows XP, check all three default Event Viewer logs for errors or warnings. Copy and paste the errors and warnings into a plain text file and print this out. Then delete the log entries.
Disconnect the computer from the network or internet and exit all programs like Instant Messenger, virus-scan, and so forth.
Run Windows XP's Desktop Clean-Up. This only cleans out the temporary files created by the person logged on at the time, however; many others are left to build up. A file and folder search for files named "~*.*" will find the rest. Most files beginning with a tilde (~) can be safely deleted.
Defragment the computer's hard drive twice in a row, then reboot the computer checking for errors, warning beeps, and other telltale noises. This tests the computer's restart ability. Check the Event Viewer for any errors or warnings that haven't already been captured.
Download, install, and run BelArc's BelManage or other inventory and software checking utility. (I often recommend BelArc because its software is straightforward; its stand-alone, non-commercial version is free; and it provides charitable software donations to nonprofits.) Make sure to print out this report.
Using the report you printed in Step 7, check for and install all the updates recommended by both the report and the software manufacturer, including software patches and drivers.
Once you've installed the updates, restart and check the logs again for errors or warnings; this time, you'll want to capture and print any that are left so that you can troubleshoot them. As appropriate, make sure to back up the computer's data first.
Finally, take the computer for a test drive, starting it up the same way the user does in the morning, opening email, the word processing application, Internet, and so on to ensure no errors are present and nothing is unusual from the user's perspective.
Additional items to consider during the "health check" include viewing and documenting configurations of common software, network settings, and other configurable options. Problems standardizing these configurations on computers in the same environment typically indicate issues either with the computer or with the network.
Well, I don't think there is really a main step, there are several important steps that are recommended.
Here are some of the main ones:
A good start is making sure you have both a Firewall (I use a program called Comodo) and an Antivirus (Avast! Antivirus, I use these two because they work well and they're free).
If you have windows 8/8.1 you don't usually have to worry about De-fragmenting your computer as it does this for you, however a disk cleanup or two doesn't hurt (You should be able to find these from your control panel search bar.
Make sure to keep your system up to date, check for windows updates or ensure that windows updates is on as this will help make sure your computer is as protected as possible (Some updates have even improved performance in some cases).

Maintenance Professionals are needed to carry out appropriate routine and non routine maintenance safely so that hardware and software are kept in good condition and up to date.

System software that is responsible for the functioning of all hardware parts and their interoperability to carry out tasks successfully is called an operating system (OS). OS is the first software to be loaded into computer memory when the computer is switched on and this is called booting.
Software or "programs" are a long list of instructions that "tells" the computer or "hardware" what to do. Without software, computers are useless. Systems software is software that controls a computer. Applications is software that a user uses to carry out a task, like a word processor. Systems software enables applications to use the hardware, organises files, manages memory and many other activities that keep a computer working or operating, hence the name operating systems.
Computers require three elements to perform a task: hardware (the physical machinery required to complete the task), software (the instructions the hardware should carry out to complete the task), and users (the people who interact with both the software and the hardware to complete the task). Although many tasks can be automated, the need for a user is still a pre-requisite as computers are not self-aware, they cannot program themselves and cannot make decisions they are not programmed to make.
While there are software solutions, you should look into a combination of software and hardware. The rovio package, for example, comes with a software package to allow this as well as a mobile robot to carry the camera around. This will allow you to get a full range of view from all areas within your household.
Even the best server will eventually either have a hardware problem or need some form of maintenance. A pair of servers working together to share the load means you can service a failed piece of hardware or do maintenance without impacting operations. When both servers are functional, load balancing allows you to get the best performance possible from your hardware by letting both servers carry the load equally, rather than consuming all resources on one server.

The 5 elements are hardware, software, user program, procedure and personnel. Data processing transforms data into meaningful information to carry out business or scientific activities.

Whether you can buy wire connectors at local hardware stores depends on the hardware store. Some hardware stores do carry wire connectors.
