what are the major factors to be concerned when buying a computer for yourself?

• Choose a specialty store, consumer electronics store, retail chain, limited service discount chain, local computer builder or mail-order/Internet vendor, based on your hardware and service needs. 
• Buy when you need to buy. No matter how long you wait for the best deal, the same configuration will cost less in six months.  
• Decide which features you'll need based on what you're going to do with the computer. For example, if you're going to be creating graphics, sound and video, you'll want plenty of RAM. If you're going to be doing heavy computational tasks (searching large databases, watching video), you'll want a super processor.  
• Decide if you want a laptop, which you can carry around with you, or a desktop model.
•  Choose a computer brand based on quality, price and technical support. 
• Based on your likely needs, determined earlier, figure out the core configuration you need, including processor and speed, amount of RAM and hard drive size. 
• Determine additional drives you need: CD-ROM, DVD-ROM, CD recorder, Zip. 
• Select peripherals and additional hardware such as modems, sound cards, video cards and speakers. 
• Decide how many extra internal card slots and disk-drive bays you'll need in order to allow room for future expansion. 
• Determine what pre-installed software you want or need. Get at least an operating system, such as Windows, an anti-virus program, and programs for word processing, spreadsheets, databases and keeping your checkbook. 
• Choose the length of warranty or service coverage appropriate to your needs.
  

Computer technologies used in the Insurance Company

Technology pays a tremendous role in the modern insurance industries. The use of computers, specifically, has allowed changes with regard to how data is retained and transactions conducted. Computers also link up branches from anywhere in the world. Communication and information transfer happens in a matter of moments. These functions make computers an extremely valuable tool in the insurance industries.

Computers are instrumental to the way the Insurance Company performs its business. This technology allows Insurance to be able to take transactions and update accounts in real time. Online Insuring is another effect of computer technology on the insuring industry; computers allow people to set up automatic payments from their bank accounts to such places as utility companies and insurance groups. The insurance industry uses sophisticated computer software to analyse risk. Automated underwriting systems adjust premiums and recommend acceptance or denial of risk for a potential client. With the use of the Internet, insurance companies are able to access information which will determine whether they accept client or not.

Computers decrease the amount of time needed to perform complex calculations and allow professionals in this industry to calculate many formulas at the same time. Computers also increase the efficiency of this industry by reducing the potential of humans to err and make incorrect calculations. Computer technology makes this information more easily accessible and also requires less amount of physical space. Records can be backed up easily with computer storage.

Comparison of Primary Storage Devices & Secondary Storage Devices.

The storage devices are broadly classified into secondary storage and primary storage. The secondary storage is known as peripheral storage, and is used to stores information of the computer that is not in current use. The secondary storage is typically slower and is of higher capacity than primary storage. The secondary storage is almost non – volatile. The secondary storage is slow due to serial access.

The primary storage is used to refer for local random access disk storage and is properly called secondary storage. If this type of storage is called primary storage, then the term secondary storage would refer to offline. This usually occurs in the slower, larger forms of storage which is used to develop vendors to provide secure device management services, authentication services, as well as encryption for data. There is software and application based solutions; however software – based encryption solutions can impact performance during the storage process. Vendors provide hardware based solutions, which are appliances that provide authentication to protect the data. These devices are taken into account for the different requirements of securing data on primary or secondary storage. The primary storage performance and access specifications for the tape environment and requires the encrypting to tape would require integration with backup schemas for primary storage scenarios.

Describe generally about total computer system & computer networking

A total computer system is comprised of many internal and external devices. The complete computer made up of the CPU, memory and related electronics (main cabinet), all the peripheral devices connected to it and its operating system. Computer systems fall into two broad divisions: clients and servers. Client machines fall into three categories from low to high end: laptop, desktop and workstation. Servers range from small to large: low-end servers, mid range servers and mainframes.

A computer network is a group of computers that shares information across wireless or wired technology. Computer networks used to only be available for corporations but they are affordable for small businesses and individuals. Computer networking requires two computers, a protocol and the hardware to connect them. Collection of two or more computers that are interconnected with each other to perform data communication using the data communication protocol through communications media (wired or wireless), so these computers can share information, data, programs, and use of hardware together.

Benefits of Adobe Dreamweaver

Browser Development - Dreamweaver is the only web design software that develops web pages that can be viewed by all web browsers.
Quick Development Time - By incorporating easy-to-create templates as well as a reusable page library, Dreamweaver can be used by experienced developers to create a robust web site quickly.
Data Processing - By using Spry Data and Java scripting to handle dynamic data, Dreamweaver replaces back - end databases.
Table less Layouts - Dreamweaver offers table less layouts for web pages. Images and text no longer need to be placed in tables.
Split Development Screen - Dreamweaver 8 offers the developer a split screen. Half the screen displays the code for using HTML and the other half of the screen is a visual representation allowing for WYSIWYG (What You See Is What You Get) development.
