Wholesale Computer Hardware – How to Find a Reliable Computer Parts Wholesaler

January 29th, 2011 Admin


With the prices of high quality computer hardware rising, consumers and businesses are seeking wholesale computer hardware at the lowest possible price. In today’s world, wholesalers for computer equipment are very difficult to find. The internet could be utilized to find the best prices for computer related items.

Since the internet is filled with websites offering wholesale equipment, choosing the right wholesale computer hardware supplier may be difficult. The reputation of the seller should be taken into consideration, there are many sites that prioritize making money and do not offer proper customer service.

Wholesale computer hardware sources for the business

Individuals who sell on auction sites must have a wholesale supplier. Who is their supplier and where are the suppliers located?

During a search for wholesale computer hardware I came across a site that offers wholesale prices for products. The site could act as a wholesale hub for products to be purchased at low wholesale prices to fill orders on auction sites like eBay. This is also a very good source for building a website of your own and selling computer hardware to make a profit.

Why buy wholesale from Salehoo.com?

Their store is filled with merchandise from reliable wholesale sources that will drop ship to your customer, manufacturers, and wholesalers to find what you need at lower prices.
Over 5000 suppliers are available to choose from to find wholesale computer hardware at discounted wholesale prices.

International shipping is also available through Salehoo.com. Many suppliers have low minimum orders or none at all. Only buy what you want as much as you want to stay within a budget.

What are the features of Salehoo.com ?

Salehoo.com offers a feedback system that will help to analyze reliability of the sources. High numbers of positive feedback means the supplier is a good source to buy from. The site also has a section dedicated to warning people of suppliers to stay away from. The wholesale supplier source Salehoo.com promotes communication between buyers and sellers before buying wholesale computer hardware as well as thousands of other products.

The website also has a liaison to help resolve issues that occur between buyer and seller and promote favorable outcomes with disputes. Salehoo.com has a forum as well to communicate and possibly find bulk discounts when buying large quantities.

What do I get with the membership?

Salehoo.com offers access to products and suppliers that will help locate the best merchandise at wholesale price. They offer over 80,000 products and over 5000 suppliers to choose from. As a bonus, members will also receive at no charge a manual on how to successfully incorporate drop-shipping into their sales and business. The guide shows how to deal with the drop-shipper and know what to expect.

The second bonus eBook offers information on what products to sell that are growing in popularity. It outlines what niche markets will be profitable this year. Members are also provided with information on how to lower shipping costs and offer free or discounted shipping to purchasers.

These are just a few of the bonuses available at no charge when a membership is purchased.

History of the Computer – Cache Memory Part 1 of 2

January 29th, 2011 Admin


We looked at the early digital computer memory, see History of the computer – Core Memory, and mentioned that the present standard RAM (Random Access Memory) is chip memory. This conforms with the commonly quoted application of Moore’s Law (Gordon Moore was one of the founders of Intel). It states that component density on integrated circuits, which can be paraphrased as performance per unit cost, doubles every 18 months. Early core memory had cycle times in microseconds, today we are talking in nanoseconds.

You may be familiar with the term cache, as applied to PCs. It is one of the performance features mentioned when talking about the latest CPU, or Hard Disk. You can have L1 or L2 cache on the processor, and disk cache of various sizes. Some programs have cache too, also known as buffer, for example, when writing data to a CD burner. Early CD burner programs had ‘overruns’. The end result of these was a good supply of coasters!

Mainframe systems have used cache for many years. The concept became popular in the 1970s as a way of speeding up memory access time. This was the time when core memory was being phased out and being replaced with integrated circuits, or chips. Although the chips were much more efficient in terms of physical space, they had other problems of reliability and heat generation. Chips of a certain design were faster, hotter and more expensive than chips of another design, which were cheaper, but slower. Speed has always been one of the most important factors in computer sales, and design engineers have always been on the lookout for ways to improve performance.

The concept of cache memory is based on the fact that a computer is inherently a sequential processing machine. Of course one of the big advantages of the computer program is that it can ‘branch’ or ‘jump’ out of sequence – subject of another article in this series. However, there are still enough times when one instruction follows another to make a buffer or cache a useful addition to the computer.

The basic idea of cache is to predict what data is required from memory to be processed in the CPU. Consider a program, which is made up of a series instructions, each one being stored in a location in memory, say from address 100 upwards. The instruction at location 100 is read out of memory and executed by the CPU, then the next instruction is read from location 101 and executed, then 102, 103 etc.

If the memory in question is core memory, it will take maybe 1 microsecond to read an instruction. If the processor takes, say 100 nanoseconds to execute the instruction, it then has to wait 900 nanoseconds for the next instruction (1 microsecond = 1000 nanoseconds). The effective repeat speed of the CPU is 1 microsecond.. (Times and speeds quoted are typical, but do not refer to any specific hardware, merely give an illustration of the principles involved).

In part 2 we consider what happens when we introduce a cache memory.

Determining If Your Computer is Part of a Botnet

January 29th, 2011 Admin


One thing that many average Windows users don’t realize is that there computer could be part of a botnet. What this means is that their computer has a program on it that is harvesting data off their machine and sending it to a location where all this data is stored. Many people write these programs which are much like viruses and spyware to get your personal information off your machine like passwords and logins to steal your accounts and even worse your identity. There are some easy steps to take to know if your computer is part of a botnet.

If you run regular virus and spyware scans, this should take care of much of the problem but some botnets are creative enough that they can avoid detection. You can detect them yourself by hitting Control + Alt + Delete and bring up the task manager. Hit the network tab on the task manager while your browser and email applications are closed. If you notice that your network is sending out and receiving information, you very well may have a botnet on your computer.

There are some steps that can be taken and should be taken immediately.

Update your virus and spyware software.

Turn off your internet connection just in case so more data is not released.

Run a full system scan in safe mode with your scanners to remove anything that may be there.

Once again turn on your connection and see if the network tab is still sending data.

More extreme options might be to reinstall the operating system which will erase everything on the computer getting rid of the botnet. Another option is to switch to Linux or Mac where botnet problems don’t exist quite as much.
