Speed Up Computer - Use of USB Flash Memory As an Extra RAM

Use windows ReadyBoost to speed up your computer

Random Access Memory in short form RAM is playing a big roll in a computer speed. These are electronic memory and always very faster than magnetic storages. There for computers use RAM to hold data currently on process. So those data can be access very quickly. High RAM capacity increases computer speed as frequently processing data temporary holds by the RAM. If your computer have big RAM, then you can work with several applications simultaneously.

Installing extra RAM card is the most effective way since last few months, to increase performance of a computer. But that was a limited resource as some computers may not exists extra RAM slots on the motherboard. Adding another RAM is cost effective and sometimes may be difficult due to incompatibility.

Windows Vista introduced new solution for this. It is called windows ReadyBoost. It is a new concept in adding memory to the system. You can use USB Flash memory (Pen) as an optional RAM. This will increases the RAM capacity and you can speedup computer or run multiple applications at the same time.

The flash memory device serves as an additional memory cache that is, memory that the computer can access much more quickly than it can access data on the hard drive. It is easy to use and you can also use Secure Digital (SD) memory for this. Windows will check the memory for the speed and you can allocate a space from your memory card and can use the remaining space to save your files.

Cheap Computer Chairs

Cheap computer chairs are low-priced computer chairs that are designed to provide comfortable sitting position when using a computer.

The climbing popularity of the Internet increases the scope for supplying cheap computer chairs. People sit before computers for Internet surfing and playing games for long hours. Unless they adopt a comfortable sitting posture before the computer, the body, which is not amenable to difficult angles and bends for long, would react adversely with back pain and other discomforts. Manufacturers are taking particular care to provide convenient computer chairs like ergonomic chairs, which can also be purchased inexpensively, for customers.

There are automatically adjusting, self-balancing, and work-environment-friendly computer chairs. The body has to move hundreds of times per day. The computer chair should also adjust to the body movements and complement the reflexes. There are many adjustable computer chairs that are made to complement any work environment, from a home office or cubicle to an executive office suite.

Besides an affordable price, a good computer should provide the necessary support to the back, legs, and buttocks so much so that proximity with the computer for long hours of work becomes easy. A good computer chair can help to create a healthy working environment. Loose ends in between the body and the chair would tax the body while it moves hundreds of times while one is working with the computer key board.

Computer Leasing and Finance - Pros and Cons

If you own a business and you have the need for computers, then you may be wondering what your options are as far as acquiring the computer equipment. There are two options that you can consider, computer leasing and finance. You should educate yourself on the pros and cons of leasing vs financing.

If you decide to finance computers, you will need to get some type of loan to finance the equipment. This means that you will have a line of credit extended to you, either through your bank, or some other financing source. The downside of financing is that it ties up some of your working capital and leaves you with less lines of credit to work with. Also, you will keep the computers until you pay them off through the payment plan that is set up when you originally finance the computers.

As you well know, technology advances rapidly. If you finance a large amount of computers at one time, you will end up having those computers for at least a couple of years, maybe more.

A big difference between computer leasing and finance is that when leasing equipment such as computers, you may have the option to get new computers on a regular basis, as you are only leasing them, not paying them out on a finance plan to eventually gain ownership of the computers.

Another difference is that if you have to acquire a loan to finance the computers you want to purchase, you most likely will have to put down some sort of down payment. This is not the case with leasing. In a leasing agreement, everything is normally one hundred percent funded, and no down payment or money up front will be required.

Your best course of action, if you are considering whether to choose computer leasing or finance for your business needs, is to thoroughly research what each option requires of you. It all depends on if you are wanting to actually buy the computers over a period of time, or if you would like to have the option of replacing the computers with newer models periodically.

How To Connect Two Computers - Windows Environment

Okay so why write about it? Well because there was once a time that i needed to know how to connect two computers together and I couldn't find any articles to help me and no links on the internet that had it in detail, so this is for the people that might experience the same.

So let's begin!

Firstly you will need to know how exactly your two PC's are going to connect. So here it is. The computers will connect directly to each other therefore no hub will be needed. For those of you that don't know, a hub is just a device that connects computers in a network via UTP STRAIGHT THROUGH cables.

The reason why I wrote straight through in caps is because this is not what you will be using to connect the two computers. Instead you will be using cross over cables. You can get this from a local computer store for relatively cheap. Or if you feel like doing work then make it, its really easy. If you need any help, then a Google search on how to make crossover cables will help alot. The reason why I don't tell you how, because I'm telling you how to connect two computers not create crossovers.

Anyways that's all the requirements you'll need, just a cross over cable. (Please note; if you buying or making a cross over, make sure it's at least cat5e UTP cables.)

Now that we got that out of the way, let's get to work!

Step1

On each computer, right click on "My Computer". Click Properties and then click on the "Computer Name" tab. Where it says "Computer description:" Give each computer a description (It must not be the same). Now click on the "change" so that you can change the name of the computer and create a workgroup. In the name option give it the same name you gave it for its description and in the workgroup section type in "my first network" (REMEMBER: Names of the computers should NOT be the same, BUT Workgroup names should be EXACT the same on both)
Now once you change these, you will be asked to restart the computer, so simply click yes or ok, whatever you are prompted with.

Step 2

After the computers are rebooted you will need to setup IP addresses for each computer. This is how:

On your desktop, look for the icon named "My Network Places". Now dpouble click it to open it.

Once open look on the left to see an option "view network connections" and click on it.

Now right click on local area network and click properties.

Where it says "This connection uses the following items:"; scroll down to "Iternet Protocol (TCP/IP)", click on it and click the properties button.

Now click on "Use the following IP address" and at "IP Address" type in an IP address e.g 192.168.0.1.

Although you do the same steps for both computers you must have different IP addresses so you can make the second computers IP address 192.168.0.2

After you set the IP addresses just press the tab button and you should get a number in the subnet mask as 255.255.255.0, then press ok and wait a while and now you almost done!

Step 3

This is the easiest part; just take you cross over cable and connect to each computers network card RJ45 port. That's it you now will be able to see the computers in "My Network Places". You may start sharing files!

Computer Appreciation For Beginners (Part 2)

In this part of the article 'Part 2', I intend to focus on the classification of computer. It is of great important to know of the classification a particular computer system belongs, as this will help in clear differentiation among them when come across.

Classification of Computer:
In this section, we give the classification of computers by the type of data they process, Purpose and Physical Size.

Classification by Data Process:

Digital Computers:
The digital computers convert all input data into binary form; process the data in binary form but the processed information is converted back to decimal form. The output from digital computers are usually discrete values. Digital computers are very accurate; examples include desk calculators, some personal computers and adding machines. Most business applications use digital computers.

Analogue Computers:
Analogue computers represent data in continuous form using physical quantities. Their accuracy depends upon the measurement made, and so not as accurate as the digital computers. These types of computers are used for scientific or engineering purposes. Examples include petrol pumps, speedometers, voltammeters and all such instruments.

Hybrid Computer:
Hybrid computers combine the best features of analogue and digital computers. Using digitizers, hybrid computers accept analogue inputs and output digital values. They are used in highly scientific environments. The hybrid has the speed of the analogue and the accuracy of the digital computers.

Classification by Purpose
Using this basis, the two major classes are explained below:

Special Purpose Computers:
These are computers designed to carry out specific tasks. They have in-built programs, which are stored in a part of the main memory called Read Only Memory (ROM). The content of this type of memory can be accessed and executed by the computer but cannot be modified by the user. Examples are computers designed for use in digital watches.

General Purpose Computers:
These are computers that are not specifically designed or built for specific jobs. They solve various kinds of problems depending on the program or software loaded into them. Their main memory is typically, Random Access Memory (RAM). Example of these type of computers are found in business, commercial and scientific environment.

Classification by Physical Size:

Microcomputer: Microcomputer is at the lowest end of the computer range in terms of speed and storage capacity. Its CPU is a microprocessor. The first microprocessors were built of 8-bit microprocessor chips. The most common application of personal computers (PC) is in this category. The PC supports a number of input and output devices. Examples of microcomputers are IBM PC, PC-AT etc.

Mini Computer: This is design to support more than one user at a time. It possesses large storage capacity and operates at a higher speed. The mini computer is used in multi-user system in which various users can work at the same time. This type of computer is generally use for processing large volume of data in an organization. They are also use as servers in Local Area Networks (LAN).

Mainframes: These types of computers are generally 32-bit microprocessors. They operate at very high speed, have very large storage capacity and can handle the workload of many users. They are generally use in centralized databases. They are also use as controlling nodes in Wide Area Networks (WAN). Examples are DEC, ICL and IBM 3000 series.

Supercomputer: They are the fastest and most expensive machines. They have high processing speed compared to other computers. They have also multiprocessing technique. One of the ways in which supercomputers are built is by interconnecting hundreds of microprocessors. Supercomputers are mainly being used for weather forecasting, biomedical research, remote sensing, aircraft design and other areas of science and technology. Examples are CRAY YMP, CRAY2, NEC SX-3, CRAY XMP and PARAM from India.
