As we know that now the technology has been developed with very sophisticated at all and many companies that utilize these technologies to help business run more advanced and offers many advantages. One technology that is certainly exploited by a company is information technology, like computers. A large company usually has several branches and to be able to help so that between head office and branches can be connected, hence made a computer network. The head office would require information quickly from branch offices, and vice versa.

The important thing to note is regarding the Equipments used in making inter-company computer network. Equipments companies should use the best quality and reliable. If you are looking for good quality network Equipments, you should choose Used Cisco Equipment. Because good computer networks will continue to maintain cooperation within the company and hopefully the company gets more profit.

Tracking systems give you the ability to keep tabs on all company vehicles fitted with it. Such systems will enable you to cut down considerably or even put a stop too staff who skive off. Vehicle tracking can help to put an end to false over time claims or over estimating how long jobs will take. Solving just these three problems can save a company a fortune every year and more than pay for the vehicle tracking system, but these are not the only savings that can be made with a vehicle tracking system.

Tracking can also help to cut costs in other areas too. When businesses choose to install vehicle tracking they can also save on their insurance as security is increased with a vehicle tracking system. In fact because of the increased security that tracking offers diggers and tractors are now being fitted with GPS plant tracking.

The topic has been raised recently in Britain with people encouraged to try and find a ‘Broadband Buddy’ to help them learn about using computers and the internet. Many of these very people have kids and relatives who love gadgets and are with the times, yet despite that they couldn’t tell you the best games console for love nor money!

Despite the shortfalls in the education of the individuals involved time and money in being put in to try and help them. The governments is acting to try and achieve there targets of having everybody connected to the web. And not so far from now everyone should not only have the access but super speedy connectivity in the form of broadband, which in the UK is currently not the most rapid for many parts of the region.

With the continued help from others though no doubt in the not too distant future nearly 100% of people will be surfing for information and doing shopping for everything from household toiletries to digital cameras for kids and even the odd wedding dress!

The truth is that computers are not slow as they age, a slow computer is a signal that something is literally holding your PC again and affecting performance. And the good news is that you can do something about it.

There are many things that can affect the performance of the computer’s memory to a low of disk fragmentation and everything in between. Things that can affect your computer’s performance often make their own. You see, every time you download a program or delete a program that affect the way your computer works. This change in the operation may leave holes in your PC or operating procedures can leave behind even the programs that can affect the performance of our computer.

Here are some things that could slow your computer:

Background Running Programs - These programs are software applications that run behind the scenes, even when not in use. You may not even know they are running, but that can zap precious memory and slow down considerably more. To see if you have programs running in the background, press Ctrl + Alt + Delete keys simultaneously. The box will show all running applications.

Full Hard Drive - If your hard drive is too full of data, will not have enough space to perform household chores. Your hard drive must have at least 2MB of free space on 3 MB.

Fragmented hard drive - When you download and delete programs, it creates holes in the hard disk. These holes meant that the PC has to find the files it needs over a distance and not necessarily in the order they are needed.

More Pieces of the left - When installing and uninstalling Windows programs, they leave behind parts or applications that can slow down your computer. Even without knowing it, you can delete a file needed for other software applications. (Note: Spyware and viruses can also slow the performance of your PC, but for the purposes of this article we are assuming that the problem lies in application errors.)

Make your PC run like New

Although it is not rocket science, making your computer lightning speed, once again, have a little work from you. Sometimes this is as easy as its Windows operating system tools program. You can find these programs by clicking on “start”, “all programs” “accessories” and “system tools”. Here you will find several system optimizers to help you release the disk space, defragment your PC, and detect and repair disk errors.

In addition to the tools already installed on your PC, you can choose to download additional software to optimize your computer’s performance. These optimizers can be purchased as a package with other software programs that can help you get the most from your computer. These are just some of the extra optimization that you may want for your PC:

Memory Optimizer - When you are using your computer, it takes several programs and the application to handle everything you’re doing. Each of these programs uses memory. When memory is short response time of the computer is slow. Memory Optimizer helps the memory allocation for each program more efficient. This can help eliminate the slow run-time PC, Windows hang or crash, data loss and unwanted machinery.

Register Deffrager and Optimizer - As mentioned before, a record with holes results in slow response times as the search for the data to your PC needs. This program improves the system response time and saves memory by creating a lower register.

Windows Optimizer - We all use our computers differently. Some use your computer as a media center and entertainment, while others use their PC for data storage and business. Windows Optimizer allows you to modify the program settings to be done in accordance with their needs.

Of course, a slow computer is a nuisance and may stop wanting to go out and buy a new model. But before you abandon your current model, make sure you’ve optimized first. You may be surprised at how much life is still in your PC.

The key to finding the laptop for you is determining what your needs first will be, then determining how much money you are willing to spend.

There are some general factors to consider. The first is the size of the laptop. Want an ultra portable laptop that small and light weight or want something more like a desktop replacement, while compromising the size and weight.

The second factor to consider is the size of the hard disk of the laptop. Portable hard drives are much smaller than desktop hard drives. A portable hard drive size would be around 100GB. If you need to store large files like videos, then you should get something with the update disk.

The third factor is the size of the memory. A standard size is 256-512mb. Anything above this cost. You would have to consider what you will be using the laptop for. If word processing and web surfing is all I want to do then 256mb would be more than enough.

The last factor would be price fixing. This is totally a personal choice, but you get what you pay for. Laptop prices have fallen dramatically in recent days and a laptop can be purchased for as little as $ 1000. Taking into account a couple of years ago could not get a laptop for under $ 2000, this price is not too bad. But, of course, everything returns to their needs. If a high-end laptop is what you need for video or image editing then expect to be paying more than $ 2500.

Buying a laptop is not necessarily a difficult task. If you assess your needs first, and carefully select your new purchase will be a profitable.

Choosing your motherboard does not have to be a problem, although there is much to consider. Let’s start with the major parties and move forward on things that are less essential.

First is the type of plug. The base is where the processor (CPU) connects to the motherboard. No compatiblility between shots, so it has to be correct. The socket connection must match the connection of the processor that has or intends to purchase the equipment.
The age of Intel Pentium 4s use socket 478. Using the new socket 775. AMD socket A chips used for a long time, but now the AMD Athlon 64 and Semprons use socket 939. Just see what someone with his or her intention to have one.

Your choice of chip will have much to do with their needs, but choosing one with a socket to date type of board a little more secure in life as you can upgrade the chip for a while.

DDR RAM is the memory of choice for most systems, but some newer systems, which includes all Pentium socket 775 use DDR2. These two types are not interchangeable and have a different number of pins. DDR and DDR2 come in different speed ratings measured in MHz DDR 400MHz usually called PC3200 or DDR400, DDR2, whereas you can go a little higher and comes in slightly faster speeds. Just make it match what the board needs.

A mother should be chosen carefully to match the time the rest of the components and the adjustment in the event that you choose. A little research before buying and you’ll save a lot of problems later.

Many a times there are chances of you being cheated, if there is less amount of focusing on the money you have invested. Many people have lost their house because they have not paid their mortgage at proper time. Some people make a good use out of it as they are on the safer side and this happens because of their precautionary measures that they take before taking a loan from a bank or from a lender. The latest trends over the last 30 years have suggested that the mortgage industry have come down the cycle. Most of the people in today’s world are unaware of it.

Essential Tools required:
1) A screwdriver (Cross-shaped)

Optional Recommended Items:
1) Torchlight (To illuminate hard to see areas)
2) Antistatic wrist strap (To discharge of any static charges)

Let¡¯s start now. Firstly, discharge yourself of any static charges by touching the metal casing or attaching the other side of the antistatic wrist strap to the metal casing.

1) Open the case

2) Install the motherboard
Find the motherboard standoffs that should have come with the case. Insert the I/O Shield that came with your motherboard. Now locate the screw holes on your motherboard and find the corresponding holes on the motherboard plate (or tray) in the case. Put a standoff in each of these holes on the tray and position the motherboard so that you can see the holes in the top of the standoffs through the screw holes in the motherboard. Now fasten a screw through each of the motherboard screw holes into the standoffs underneath. These screws should be snug but not tight. With the motherboard in, we are now able to start adding in other components.

3) Install the CPU.
As I mentioned earlier, the processor (CPU) and motherboard go hand-in-hand, so you should spend some time planning and researching what you really desires and buy compatible CPU / motherboard components, just like the importance of buying the right shoe size for yourself. Given that this is a minimum system upgrade, you are saving up quite a bit through reusing other components; I suggest you build a better performing system so that it can serve you for several years to come.

Before start, please read the manual provided with the motherboard/CPU carefully, understand the different parts, and the installation diagrams before proceeding. Then again, it is not very difficult with only 3 simple steps to success.

1st step to success: Install the CPU
I will be using Intel Socket 775 as illustration as it is the latest socket used so far.
-Remove the protective socket on the new socket protecting the pins
-Open the lever and lift up the metal flap so as to install the CPU
-While carefully holding the CPU at the edges, look for the notch in the corner and match it up with the socket. Slowly lay down the CPU in the socket, before lowering the metal flap, and closing the socket lever to secure the CPU.

2nd step to success: Install the CPU heatsink
If you like to go to a cool place to enjoy some aircon when you are hot, the same can be said of the CPU which you have just installed. We need to dissipate the high heat generated by the CPU so that it would not overheat and fry.
-I am recommending getting hold of some thermal paste which you can apply evenly on the CPU surface for better heat conductivity and dissipation. (To note: Intel? boxed processor already come with their integrated thermal solutions, and so does not need extra efforts)
-Align heat sink onto the Socket containing the CPU, with the fan cable orientated closest to fan power connector, and check for any entanglement.
-Press down on fastener caps with thumb to install and lock. Repeat with the other 3 fasteners.

3rd step to success: Power up the heat sink
This is done by connecting the fan cable from step 2 to the CPU_FAN connector located on the motherboard, which is located very close to the CPU. Tie up excess cable to prevent interference with fan operation or other components.

Congrats, by the time you finished this, the rest should be a breeze already =)

4) Install the Memory

With a new motherboard and faster processor, we will then need more RAM (random access memory) to enable and facilitate this faster performance. Again, you should spend some time planning and researching on memory which is compatible with the new CPU and motherboard you have installed to bring out the best overall performance. To install the RAM modules, you need to unfasten the clips located on each side of the memory slot. Align the RAM module in the socket, such as to match the indent located on the memory chip and the memory slot, for the right facing direction. Push down on the memory module until both clips refasten and a click sound is heard. To change memory, simply press down the both clips at the same time, and the RAM will come out easily.

TIP: Start adding RAM at the slot labeled ¡°Bank 0¡± or ¡°DIMM 1¡±. If you don¡¯t, the system will think there is no memory available and wont boot.

TIP:For newer systems supporting hyper treading technology, you are encouraged to use the dual channel memory functionality by placing 2 sticks of the same memory on alternate slots (i.e.: slot 1 & 3 or Slot 2 & 4, often differentiated by color as well. ) This has been proven to enhance the performance as well.

After installing the new motherboard / CPU, and memory, you are already DONE installing the New essential items you have bought. YEAH!! Now that is left is to migrate the remaining items from the old pc to your “Brand New” PC. =)

5) Install the Power Supply

There will be a bracket at the top of the case where you can mount the power supply, and secure the power supply using screws. The power supply will consists of the following connectors: ATX power connector, ATX_12V connector, IDE power connector, and FDD power connector. Look for the 20 or 24 pin ATX power connector, and plug it into the motherboard allocated power slot. There may also be an additional four or eight pin power lead on the motherboard that needs to be plugged in, which is usually located near the processor socket. Do double confirm with the motherboard manual for details.

TIP: You might want to consider getting a new power supply which rating is at least 300W so as to support any future upgrades you have in mind.

TIP: You need to select the right power supply settings (115v or 220v) depending on your country settings. For newer power supplies, it is equipped with automatic detection, so that will not be an issue at all.

6) Install the Floppy drives/Hard-disks/DVD writers

Floppy disks, Harddisks and DVD ROM/writers communicate with the CPU through data cables commonly called FDD/IDE cables, although newer harddisks now connect via SATA cables for faster data communications.

Note: FDD Cable for floppy disk drives appears smaller and has fewer wires.

Note: Using multiple hard disks If you have intention on using multiple hard disks, you must adjust the settings on the multiple disks to inform the computer system which is the main disk and the other supporting/additional disks. If not done properly, the system can get confused, and the disk may not boot at all. Do read the simple instructions as shown on the harddisk surface for the right way to place the jumpers so as to distinguish between the master drive (main operating system) and the slave drives (other files/documents). This instruction varies across different harddisk manufacturers. This configuration should be done before inserting the IDE cables.

First, remove the front casing of the computer, and remove the 5.25″ plate so as to expose the front of the DVD drives later. Similarly do it for the floppy drive plate. Insert the IDE cables into the floppy drive/ harddisk/ DVD data connector noting the orientation of the notch in the centre, so as to insert in the right directions. The remaining connector is to be connected to the motherboard. Next, to power up the drives by plugging in the 4 pin molex power connector from the power supply in step 5 into each hard drive and optical drive. For the floppy drive, the power plug is also 4 pins in a row but significantly smaller than that of the hard disk. Need to take note of the power connector orientation as well.

Final securing all disks and optical drives with screws before securing back the front casing cover.

TIP: Recommend that the IDE hard disk be connected to the IDE 1 connector and the optical devices connect to the IDE 2 connector. Maximum of 2 IDE devices per IDE connector. If using multiple IDE hard drives, you should enter BIOS later on and set their boot sequence accordingly.

7) Install the Video Card

For older motherboards, we typically see AGP video card being used, which will be installed onto the AGP socket, which is often brown in color. For newer systems, PCI Express video cards are more commonly used due to better data transfer performance and better resolution performance. Both AGP and PCI Express slots can be identified easily, and is usually located adjacent to the CPU unit.

Now, insert the card into the slot with some force, and check that it is fully inserted with no protruding edges, before screwing it in at the top of the metal bracket. If it has a power connector, connect it with a 4-pin molex connector.

Remaining Internal Connections
-Connect the audio cable from the DVD to the motherboard CD_IN connector (if required)
-Connect the power/reset buttons, and signal indicators (those external blinking lights) to the F_Panel connector on the motherboard. (i.e: Power indicator, hardware indicator, internal speaker, etc…). Read individual motherboard manual for clearer inserting of these signal connectors.
-Double check on proper power connection to all hardware components
- (Optional) Install extra items such as front mounted USB, firewire and/or sound ports.

At this point We are 90% done with our DIY PC Assembly already !! Do not put back the casing covers as yet.

9) Final External Connections
-Connect back the outer devices including items like
a) Keyboard
b) Mouse
c) Monitor
d) Printer / Scanners
e) Speakers
f) External power supply cable

10) Bring on the POWER!!
This brings us to the last stage of the PC assembly process. If you have done everything right, now is the time to sit back and savor the fruit of success.

With the casing still open, and all external peripherals connected, turn on the computer and observe for any abnormality such as fan not spinning, or beeps alarms from the PC. If so, turn off the power and spend some time checking through the connections, and also the manual for some tips on troubleshooting.

Well, if you observed no abnormality till far, and you have seen the splash screen from the motherboard, CONGRATULATIONS!! You have succeeded in building your own PC

Next step is to

Choose and Install your Operating System
Click below for latest deals

if using a brand new harddisk, and this can be done by changing the boot options in the BIOS to Floppy, then CD-ROM, then Hard Disc. Insert the original bootable operating system disc in the DVD drive, and start your computer and follow the instructions in the disc to install.

Once your operating system is up and running, the rest of the show is all YOURS !! =)

CONCLUSION

———————————————————————————————–

In this tutorial, I have shared valuable information with you in building your own PC with minimal updates, so you can customize your PC to your needs and maintain very affordable. I have also shown that the details of the installation of various components of PC, and I hope it will be informative and useful to help you with Headstart.

With knowledge comes power, and hope that are now highly motivated to start their own  PC Assembly in the comfort of your own home. =)

First, the most important component of the computer is its processor. It is considered the heart of the team that does all the calculating and processing. But with all that calculating and processing, computer gadget is not so remarkable if not for his incredible memory. Computer memory keeps important information in a computer. These data can be used again and again they found some stored data is needed. Without the computer memory, the processor will not have facilities to store your calculations and important processes, making them useless.

There are different types of computer memory responsible for storing the different data types. They also have different abilities and skills when it comes to storing data inside the computer. The best known is the memory of the computer RAM, also known as random access memory. It is called random access because any stored data can be accessed directly if you know the exact row and column that intersect a memory cell. In this type of computer memory, data can be accessed in any order. Otherwise RAM is called SAM or Serial Access Memory, which stores data in a series of memory cells that can only be accessed in order. It works like a cassette tape where you have to go through other memory cells before accessing the data you are looking for.

Other types of computer memory include the ROM or read-only memory. ROM is an integrated circuit already programmed with specific data that can not be modified or changed, hence the name “Read Only”. There is another type of memory called virtual memory. This type of memory is a common component in most operating systems and desktops. Helps teams of RAM to be freed with unused applications to make way for loading current applications being used. It works simply by checking the data stored in RAM is not being used lately and that is stored on the hard disk, freeing up valuable space in RAM for loading other applications. A virtual memory will think a team that has almost unlimited RAM inside it.

Another type of computer memory that has made computers process tasks faster is called caching. Cache memory works simply by having current applications, calculations and processes stored in its memory instead of directly to the main storage area. When a process is in need of data previously used, first try to access the cache memory if such data is stored there before accessing the central memory storage. This frees the computer to search data in a larger memory and larger storage area for the extraction of data and faster. Computer memory is in a constant state of development as more and more technologies are being developed. Who knows, maybe in the near future computer memory might also be fit for human consumption.
