Hard Drive Maintenance
Usually the laptop hard drive is easier to wear out than desktop’s. To keep the health and prolong its lifespan, you need to do some regular maintenance of your own. The laptop drive’s longevity pretty much depends on your own habit of using a computer. Here are three basic steps you need to carry out regularly to ensure the longevity of your laptop hard drive.
1. Ensure plenty of available space. 
It is always a good idea to make sure there is enough free space on the hard drive for saving new large files, you can backup the large file of computer to another medium like CD-R, DVD-R, flash drive, or external drive, because a full hard drive can be wears out much more quickly.
2. Defragment hard drive regularly.
If you have many big files in your computer and they were move frequently, then defragmentation is very important at this point to eliminate the file fragments, it is recommended to do the defragmentation once a week. You can go to Start > Programs > Accessories > Disk Defragmenter to get access to the toolkit, or you can perform fragment analyse first before you decide to defrag a specific drive. The entire process may take more than an hour. If you got a massive drive which exceeds 500G, to get a 3rd-party software like Advanced Defrag, O&O defrag can save you a lot of time.
3. Remove the unnecessary files
Unnecessary files can be easily ignored by PC users, these unwanted files such as cookies which are downloaded without users’ knowledge when you surfing the net.
Computer Networking Services
A computer network is the practice of linking two or more computing devices together for the purpose of sharing data. 
Networks are built with a mix of computer hardware and computer software. This interconnected system will share services and interact through a communications link. If data is being sent over the system then the individual computers must follow a set of common communication rules in order for the data to arrive at is correct destination. This is also vital for the systems to properly understand each other otherwise data will not be received. These rules are known as protocols.
So, in order for a computer network to be set up properly four things must be present: two or more systems, something to share (such as data), a communications link or physical pathway, and a set of rules for communication or protocols.
Wireless computer networking uses radio waves and/or microwaves to maintain open communication channels between computers. This version of computer networking is a more modern approach and is an alternative to wired networking. The advantages of wireless computer networking are that this involves mobility and the elimination of a copper or fiber optic cabling running between computers. However, a wireless computer network has the potential to have radio interference due to weather, other wireless devices or obstructions.
If you are unsure what type of computer network you would like you can have a trained professional come to your home, business, or other location and have them recommend what you need depending on what you are using your network for. You should always hire a trained computer specialist when setting up a computer network as there may be complications and it can be very difficult to learn how to set up a computer network by yourself.
Home Networking in the Digital Age
When computers first became available to the general public, it was rare for any home to have more than one unit, let alone a network of computers. But as modern technology became cheaper, more accessible and within the reach of everyone, tech-savvy homes are now linking up their laptops and plugging in their PCs into home networks.
What is a home network?
A home network is simply a method of allowing computers to communicate with one another. If you have two or more computers in your home, a network can let them share:
· Files and documents
· An Internet connection
· Printers, print servers and scanners
· Stereos, TVs and game systems
· CD burners
To set up a home network, you’ll need a few basic components including more than one computer, hardware such as a router and software, either built in to the operating system or as a separate application, to co-ordinate the exchange of information. You will also need a ‘path’ for the information to follow from one computer to another. This is usually supplied via a WiFi system. The two most popular home network types are wireless and Ethernet networks. In both of these types, the router does most of the work by directing the traffic between the connected devices. By connecting a router to your dial-up, DSL or cable modem, you can also allow multiple computers to share one connection to the Internet.
Any risks?
With any network, there are always risks. If all of your computers are connected to the same network, a virus uploaded onto one computer will infect all the other computers linked to the same system. This is why it is imperative that you install effective firewalls and anti-virus software into your network to protect your system from outside attacks.
Most routers combine wireless and Ethernet technology and also include a hardware firewall already built into the system, but you can increase your security by adding your own software protection. Software firewalls installed onto your computers block all incoming information by default and prompt you for permission to allow the information to pass. In this way, a software firewall can learn which types of information you want to allow into your network. It is advisable to regularly update your firewalls and anti-virus protection to keep hackers and malicious users at bay.Ethernet and wireless networks each have advantages and disadvantages. Wired networks provide users with plenty of security and the ability to move lots of data very quickly. They are faster than wireless networks, and very affordable. However, with wired networks, the clue is in the name - you will have cables linking your network so if you’re not happy about a house full of cables to connect your system, a wireless WiFi network may be a better and more user friendly option. The system itself may be slower, particularly if a computer is further away from the main router, but you do cut down the amount of hardware and cables needed to create the network in the first place.Wireless networks are more susceptible to interference in the radio waves due to walls and distance of networked computers from the wireless router, but do allow you the freedom to utilise the system anywhere in the house (or even outside in the garden). Wireless networks are by far the most popular home networking system, despite some drawbacks and as the technology improves and routers become more powerful, are becoming the networking option of choice for the majority of home users.
Tips to a Healthy Computer
Re you sick and tired to fix your computer? Do you feel like you to waste too much hour and money on repairs? Well, you are in the chance because we are here to help! With these simple ends however valid, your computer will not be any more one disturbance. Believe it or not, there be much of small things which you can make to prevent of the important catastrophes of computer. If you belonged to a small company, a multinational, or right a domestic user, these minor suggestions will help to maintain your computer in the form of first order.
1. Old hardware
Studies have shown that most computer difficulties are a result of old hardware. After about 24 to 36 months, the likelihood of problems increases significantly. With computer prices rapidly declining, one major repair bill might even cost you more than a new system. Therefore, consider replacing your system every 3 years—it may save you more in the long run.
2. Power protection
In addition to data loss, surge and power drops can cause significant damage to sensitive components and even reduce their lifespan. For the most part, surge damage occurs over a long period of time without obvious signs of impairment. Ultimately, this means they will wear out over time. One way you can prevent this is by replacing your surge protector every two or three years.
3. Illegal software
Nowadays, many software programs automatically report their usage via the Internet. Although this may seem unimportant, many businesses don’t realize that they don’t own software—just the licenses to use it on a specific number of desktops and laptops. As a result, breach-of-license letters and audits from software manufacturers to businesses are certainly on the rise.
4. Training
According to recent research, most employees understand less than 20 percent of the software products they use. Although training your staff may seem like a waste of money at first, the gain in productivity far outweighs the cost.
5. Firewall and security
The Internet is full of hackers who are trying to steal files or customer records and delete important data. For this very reason, it’s important that your computer is updated with the latest security patches, including proper installation and maintenance of firewalls. Remember, this general rule also applies to laptops and tablet PCs.
