Tips For Buying A New Laptop

Buying a new laptop is something that I would consider a fairly major purchase. To start with, I would like to state that I have actually worked for a retail company that purchases and sells everything that has to do with computers, and being a salesmen, I would like to contribute my knowledge to properly purchasing a new laptop. This especially applies to those who are buying a new laptop for the first time, or buying a computer for the first time.

Step 1 - Define your goal, and figure out your requirements

Hopefully that title does not scare you. Basically, the first question I ask someone, when they are purchasing a laptop is: What are you going to be using it for? Generally, responses are quite simple: I need it for work, or my daughter is going to school, or I am a gamer and want to play the latest and greatest games out there. This is when you should consider answering that question yourself. However, before you do that, there is one question that you must answer for yourself, and that is: Are you or someone that uses your laptop, ever going to play new 3D games on it?

If your answer is:

NO: If your answer is no, then you have narrowed your selection of laptops down by about 25% - 40% (Depending where you are buying them from). An important thing to keep in mind is that, if you are not playing games on it, you do not want a "dedicated graphics card" on the laptop, because you will never use it for what you are doing. The dedicated graphics card is a costly piece of material and it will not speed your laptop up for word processing, or the internet, or even your video editing.

YES: If you answered "yes" to the fact that you would play new 3D games, then you absolutely need a laptop that has a "dedicated graphics card" in it. When you talk to your sales representative make certain they know you will be playing games on it, and that the card itself has 128Mb of video ram, or more. Another point that you MUST watch out for, is that many laptops have an "on-board graphics card". Do not get stuck with an on-board graphics card, if you intend on having a gaming laptop. The quality of games will be considerably horrible, and you will wish you re-read this article. As of writing this article, the more expensive, and thus better cards are GeForce 7600 Go, or 8600 cards, or some of ATI's Radeon X1700 or better. You will have to discuss with your representative your budget, and how fast you want your games to run.

Now that you have figured out whether or not you will be gaming on your laptop, you must consider the other software you will be using, and what kind of processing power, and memory you will want on your laptop. To make things easy I would suggest reading the software requirements of the programs you will be running, to get an idea of what you will need to run that software.

Step 2 - Identifying your wants

This could almost be the final step, if not for some last minute notes. This step is very straightforward. You must decide for yourself how fast you want your machine to be. This is a critical step, because as soon as you purchase your laptop, you cannot change anything inside of it! The one exception is the memory, and that can always be upgraded. A general rule is, the more you pay, the more you get. Below, I will list in order of importance, the general components of the laptop that you are interested in:

1) CPU - This will determine how fast your machine launches programs and runs ( You will want at least a dual-core, unless you cannot afford it ). Look for Pentium Core2 chips, or AMD's X2 type chips. Ask your product rep for a range of processors, and more information or guidance if you need.

2) Memory (RAM) - This is where all your programs store their temporary information. So, like our brains, the larger the amount of ram, the more programs you can have running, or you can launch larger programs. *Note: If you skimp on this item, you will sacrifice a lot of performace (1 Gigabyte is generally the minimum, 2 Gigabytes will be the recommended).

3) Hard drive - This part is where you store your files for the long term. Accounting books, and music files, are all stored on the hard drive. The larger it is, the more files you can cram into it. Performance of your laptop is not affected by the size of the drive, and generally not by the speed of the drive. Hard drives will range from 80 Gb - 200 Gb (Sometimes more).

Generally those are the three most important components you will need to look at in all the laptops. Now I wish to share with you some final notes.

3) Final notes, and considerations

a) If the laptop you are considering purchasing is going to be over $1200, I would greatly consider buying a "Total care warranty". This will run for 20% - 30% of the laptop price, but will cover any drops, wear, split liquids, etc. for 2-3 years. This is definitely worth considering, as I have seen many laptops with cracked screens, and to replace the screen, you are looking at $800 with labor and parts at least.

b) Brands do not matter a whole lot. Most, if not all laptops are manufactured by a global electronics company, that fills orders for many of the major brands you will see. So do not judge based on brand name, and do not judge based on looks. You will here many people tell you that "such and such a brand is no good" and some brands will be praised. To each their own, good luck shopping!

Mobile - Easy To Carry Around, Easier To Lose

The luxury of mobility. It's wonderful to be able to access your network from Starbucks. Some days you even telecommute. Oh WiFi, every networker's dream. What's scary in this whole scenario is the size of these full blown network devices. Extra small!

Even more frightening is, as always, the problem of lax security and misconfiguration. These mobile devices have now given your network a dynamic reachability. The clients roam, even into the wrong hands. It is imperative that administrators dedicate time for user training and awareness. Holders of mobile network devices should be trained on acceptable use, due diligence and care. A firewall cannot protect against an "authorized user". Authentication schemes should be checked, double checked, updated and tested. VPN technology is great, but if misconfigured it is like having an open door on an otherwise secure house.

Another issue with mobile devices is manageability. These devices should be inventoried and checked without announcements. Delinquent users will never be identified if audits are preannounced . It's synonymous to the police announcing when they are going to raid a crime spot. Users should be held accountable for maintaining the integrity of the network. Being small, again they become problematic in terms of the number, access points, PDAs, WLAN cards, they are infesting today's networks. Some manufacturers are already implementing RFID systems to track mobile devices. However, all of these security policies are doomed to fail without user training.

Recommendations:

* use strong encrytion

* two way authentication.....802.1x is ideal

* WEP should be a last resort

* walk about surveys

* educate users, from top down, that includes upper management

* IPS, WIPS, location tracking

That's all for now folks.

Is It Really A Threat To Wimax Technology?

By the time we are facing different kinds of threats and other vulnerabilities to WiMAX technology like the earlier version of wireless networking for example; Wi-Fi. WiMAX is also facing these threats, but we need to make it more secure and protect it from being failed before its deployment. Until today we are still not finding the WiMAX everywhere but we are still waiting for its success and deployment. In some areas of the world WiMAX is deployed and still undergoing to its maturity period and facing threats and vulnerabilities. As I have studied that the WiMAX is facing Denial of Service attacks, jamming of the network, management message modification as well as the data modification communication attacks.

According to the research some of the solutions and enhancements are under consideration for security of WiMAX technology but there is a need for further research in this domain because of the immaturity of the WiMAX itself. Some experts claiming that the WiMAX technology cannot get a chance to gain the target market, but on the other hand people are still expecting more out of it. According to my research and studies about the WiMAX, there are some possible solutions and enhancements that can make it more secure but not completely free of threat and other vulnerabilities.

Integration of WiMAX with other new technologies can make it more robust, reliable and secure like IMT-Advanced but we have to wait until at least 2010. Some other future technologies are also expected that might offer WiMAX a better environment and system integration to work better then any other technology in the market.
