COMPUTER REPAIR- WHAT YOU NEED TO KNOW

Has your computer been testing your patience for a long time? Picture this: you're in the middle of emailing a crucial report to your boss when suddenly, your computer freezes and doesn't respond to your desperate mouse clicks. Or it restarts every now and then, and you wonder why it happens all the time. Don't lose your cool-having your computer repaired can still revive the operation of your machine. If your computer is acting up, don't ignore the symptoms, either. Computer repair should be done as early as possible to prevent further troubles.

It's interesting to note that many people own computers but only a few of them know how to fix computer problems. Usually, computer owners seek the help of computer technicians to correct or solve the problem. That's why computers repair shops proliferate everyday and make lots of money from their customers.

If you're looking for a computer technician, you can find many business cards and fliers that advertise pc repair services. It'd be better if you take your computer to a small repair shop in your locality because its services are less expensive than that of large PC repair shops.

It's not enough to rely solely on the expertise of the person you hired to repair your computer. Try to keep yourself informed about computers so that you won't be deceived by unscrupulous technicians. Also, make sure that the technician you hire is competent and skilled enough. A good repair person can accurately diagnose the problem of your computer and provide a reasonable estimate of cost and repair time.

Always make sure the amount that repair shops charge you is fair. If you think the cost of repairing your pc is expensive, you can request for a detailed description of the tasks that were done and the price of each. If you're still not convinced, then you can try negotiating the price. Asking the repair shop to lower their charge can pay off in some instances.

ADVANTAGES OF NETWORKING YOUR HOME COMPUTER

Computers have become an integral part of our life, not just at work but at home as well. It is not unusual for a household to have two or more computers. Just like an office, you can network your home computers together in order to share documents, photos, video, and more. Many homeowners have discovered that a home network is an affordable solution to sharing your family's high-speed Internet connection and computing resources.

A network is a system that connects two or more computers together so that they can share information and the use of peripherals. Before this technology was readily available, consumers had to buy each computer its own printer, scanner, and Internet access. This made adding another computer a very expensive proposition.

There are two types of home networking systems, wired and wireless. As you might guess, wired systems require that you physically connect each computer or device using specialized cables. A wireless system requires no cables because it uses a radio wave to transmit data between the machines.

A home network offers a variety of advantages to the homeowner. Listed below are a few reasons that networking is so popular in many homes.

Broadband Internet Sharing: Networking enables two or more people to browse the Internet at the same time. This feature allows many members of the family to research, work, and shop at the same time without having to wait their turn. For one fee, you can provide Internet access for all of the computers in the home.

File Sharing: Networking allows you to share and access files that are stored on various computers in your network. This means that you can finish up the report on your laptop that you started on your desktop computer in the home office. You can also access photos, videos, and documents on any computer in your network. Many people appreciate the flexibility that this feature offers.

Peripheral Sharing: Once your network is up and running, you can set up all of your computers to have access to peripherals like the printer and scanner. There are substantial savings with only having to buy one device to be used on multiple computers.

Understanding Static IP And Dynamic Ip

The use of computers and the Internet will never be separated from the use of IP. Because it's here I'll explain a bit about IP, IP broadly differentiated into static and dynamic IP

If the computer uses the same IP address each time they connect to the network (eg Internet), then said to have a static IP address (fixed). If the IP address changes frequently, when the computer is connected to a network (internet), it is said to have a dynamic IP address.

Dynamic IP addresses are typically used for a simple network, broadband network and a USB modem, while the static IP address that is used to find the server in the enterprise.

Currently, two versions of the Internet Protocol (IP) is being used :
- IPv4 address to use 32-bit address space is limited

- IPv6 is designed as a replacement for IPv4, as 128-bit wide addresses, whereas IPv6 offer a huge address space.

See the weakness which is owned by WEP, has developed a new security technique called WPA (WiFi Protected Access). WPA technique is a model compatible with the IEEE 802.11i draft standard specification. This technique has several objectives in the design are: solid, interoperates, can be used to replace WEP, can be implemented at home or corporate users, and available to the public as quickly as possible.

HOW TO UPGRADE RAM IN AN APPLE COMPUTER

If your Mac is using the latest applications, chances are that your machine may become slow over time. If the delays on opening new apps, trying to work online or simply play a video on your Mac is becoming a pain, you may have thought about the price of a new machine and cringed.
You don't need to do it.
Instead of shelling out a couple grand on a beautiful new Mac, and you're handy with a screwdriver, you can simply upgrade the RAM in your machine or pay a professional if you're not confident.
First the bad news. If you have a MacBook Air, you will not be able to upgrade RAM. It's soldered onto the logic board and I would advise against it. (Breaking your MacBook Air defeats the purpose of trying to speed it up.)
Unibody MacBook: Remove the bottom cover to gain access to the RAM.
MacBook: If you have an older model MacBook, the RAM in these machines are located adjacent to the battery. Remove the battery and the memory door and pull on those little levers to gain access to the RAM.
Unibody MacBook Pro: Take off the bottom cover, disconnect the battery and unlock the RAM tabs.
MacBook Pro: Just take out the battery, the screws and memory door. Behold the RAM!
