Laptops Deals - How To Get The Best Laptop Deal Online!

Author: Helen Hecker



You're ready to buy a new laptop or replace a laptop notebook
and naturally you want to get the best laptop deal you can get
and you probably already know that looking online is probably
the best place to start. However don't dismiss looking offline
at big box or computer stores to get a feel for the variety of
laptops that are on the market.

First of all you'll want to list your needs in terms of the
features. Some important features to consider would include:
processor type, storage capacity, screen size, battery longevity
and wireless connectivity. And these will affect the pricing.

Other features and accessories include: microphone, back-up
battery, video card, power cord, GPS navigation, battery
charger, wireless mouse, sound card, CD drive, wireless network
card, adapter, keyboard, memory, laptop bag, case.

How much do you want to spend? Do you want a new, used or
refurbished laptop? Or do you want to rent a laptop?

If possible try out various models in all price ranges, even
those out of your price range, to get an understanding of all
the features available. New features are introduced all the time
and seeing and feeling the laptop in action can tell you whether
you'd be comfortable with it or not. I know many say to just go
ahead and buy online but it's better to be familiar with what
you're getting if you can. After you've tried out a few, go back
to the one that feels best. And try to stay within your budget.

If there's a salesperson handy find out if it's a good seller
and if he/she has any personal experience with it.

Find out all you can about any unfamiliar terms and features:
flat panel, TFT, LCD, wireless, extra memory, Bluetooth and
Wi-Fi connectivity for example, so you'll be well-informed.

Keeping in mind that you what to get the best laptop deal, you
can compare prices online once you know the brand and model you
want to buy. It can be confusing because there are so many
brands, different operating systems and many different features
and accessories.

Be careful about paying for features that you won't use. And
make sure to get those that you do need. Even if you have to pay
a little more to get something that would be useful, it's better
to get it for the small difference in price compared to the
value it'll be for you in the long run. Also it'll depend on how
long you plan to keep the laptop. Do you plan on selling it in a
year or so and buying a new one or do you plan to keep it for
two to three years or more. If so, make sure to get a good size
hard drive.

Salespeople may be up to date on the trends and be
technology-savvy, but if you discuss laptops with a salesperson,
be aware they may be getting bonuses or commissions for pushing
a particular brand and/or model.

Ask your friends and your computer and laptop-savvy associates
which laptop brands, models and features they like and why, and
what they don't like.

Make a list of the brands and models you've tried and those that
have been recommended to you, then start your "best laptop deal"
online search. Some of the many available brands new and used
are: Toshiba, Lenovo, Dell, Asus, IBM, Apple, HP, Compaq, Sony,
Acer, Fujitsu, Samsung, Gateway and Panasonic laptops.

You're looking for comparisons, reviews, ratings and rankings
for the laptops first of all. Look for anything negative,
because you want to know that going into a deal. Type in the
word 'problem' or 'bad' after the brand and model.

Once you have some good background information, reviews, and
negative and positive comments, you're ready to search for the
best laptop deal online. Some of the best deals can be obtained
for close-out laptop models. Many lines are discontinued to make
room for new inventory using the newest technology. You can
often get good discounts and the best laptop deals at close-out
sales.

There are also fire sales, discounted laptops and liquidation
sales. Try typing in these words one at a time along with the
brand name and model: 'close-out', 'discontinued', 'discount',
'liquidation sale', 'wholesale', 'low cost', 'low priced',
'cheapest' and 'cheap'. Although some of these tips are good old
common sense, you should be well-armed when you look for and buy
the best laptop deal online. Of course getting a free laptop
would be the best deal and maybe there is a legal way to do
that!

An Overview of the Computer Network Devices & Components

By Fiza http://www.theitlibrary.com

A Computer network is comprised of different devices to share
and transmit the data and voice as well as to boost the signals.
Network devices or components are the physical parts connected
to a network. There are a large number of the network devices
and, which are increasing daily. The basic network devices are:
Individual Computers, Server, Hub, Switch, Bridges, Routers,
Modems, Printers, DSL Modems & Routers, Gateways, Network
Interface Cards, Cabling & Wireless access point. The following
is a overview of each of these network devices.

INDIVIDUAL COMPUTERS: The personal computer is usually a desktop
computer, a work station or a laptop. The personal computers are
most widely used in any organization or for personal use. The
individual computers are the most common types of the
microcomputers.

SERVER: A server is a computer on a network, which process
request and is used to share the data and resources among the
other computers in a network. A server stores all the necessary
information and provides the different services like,
workstation computer's logon access, internet sharing, print
sharing, disk space sharing etc. There are different types of
servers e.g File and print server, database server, proxy
server, Fax server, backup server etc. A database server stores
all the data and software, which may related to the certain
database and it allows other network devices to access and
process the database queries. A file server is used to store the
data of any user on the network and a print server manages one
or more printers in a network. Similarly a network server is a
server that manages the network traffic.

NETWORK INTERFACE CARD: Network interface cards are attached
with the computer or other network devices and are used to
provide the connectivity between the two computers. Each network
card is specifically designed for the different types of the
network like Ethernet, FDDI, Token Ring and Wireless Networks.
The Network card operates on the first and second layers of the
OSI models i.e Physical layer and datalink layer specifications.
NIC basically defines the physical connection methods and the
control signals that provides the timings of the data transfer
over the network.

HUBS: Hub is a simplest network device. The function of the hub
is broadcasting i.e data is forwarded towards the all ports of a
hub, regardless of whether the data was intended for the
particular systems in the network or not. Computers in a network
are connected to a hub with a twisted pair (CAT5) cables. There
are two types of the hubs. 1. Active Hubs. 2. Passive Hubs.

SWITCHING HUB: The Switching hub (also called "switch" is the
most advance shape of the basic hub. In a basic hub all the
computers are connected with the hub and the speed of the
network is defined by the slowest computer network card
connected. For example if you have 10/100 Mbps cards in a
network and only one card of 10Mbps speed then the system cannot
run faster than the 10 Mbps. Now if you have a switching hub in
a network, it will allow all the faster connections in the
network to remain at the higher speed and still interact with
the 10Mbps system.

SWITCHES: Switch is a intelligence device than hub. Switch is a
layer 2 device. Swith provides the same function as a hub or a
bridge but it has the advance functionality of connecting the
two computers together temporarily. Switch contains the switch
matrix or switch fabric that can connect and disconnect ports.
Unlike hubs, switch only transmit or forwards the data to the
destined computer and it does not broadcasts the data to all its
ports.

MODEMS: Modems are the devices, which are used to translate the
digital data into the analog format and vice versa. It performs
the two main functions. Modulation and demodulation. A modulated
data can travel across the conventional telephone lines. The
modem modulates the signals at the sending end and demodulates
at the receiving end. Modems are required for different types of
the access methods such ISDN, DSL and 56K data modem. Modem can
be the internal devices that plug into the expansion slots in a
system or can be external devices that plug into the serial or
USB ports. In Laptops, PCMCIA cards are used for this purpose
and many new laptops having the built in integrated modems. The
specialized devices are designed for use in the systems such as
handheld computers. In ISPs where the large scaled modems are
required, rack-mounted modems are used.

ROUTERS: Routers route the data between two logically and
physically different networks. A Router has the capability to
determine the destination address for the data and hence
provides the best way for the data to continue its journey.
Router gets this capability through its software called routing
software. Unlike Switches and Bridges, which use hardware
configured MAC address to determine the destination of the data,
router uses logical network address such as IP address to make
the decision in determining the destination of the data.

GATEWAY: A gateway performs the function of translating the data
from one format to another format without changing the data
itself. A gateway can be a device, system, software. A computer
with two NIC cards can function as a gateway. Router acts as a
gateway e.g a router that routes the data from a IPX network to
a IP network is technically a gateway. The same can be said of
translational switch converts from a Ethernet network to a token
ring network.

CABLES: There are two most common types of the cables. 1.
10baseT and 10base2. 10baseT is a four paired cable. 10baseT has
further two types 1. UTP (unshielded twisted pair) and 2. STP
(shielded twisted pair. STP is most secure cable covered with
the silver coated twisted paper to protect the cable. On the
other end Thin 10base2 looks like the copper coaxial cabling
that often used to connect TV sets and VCR. 10baseT/Cat5 cables
are most commonly used cables to connect the computers. It has
the connector, (like a telephone connector) called RJ45
connector.

Twisted pair cables are ideal for the small, medium or large
networks. My recommendation for using cables for computer
networking is to use 10baset/Cat5 cables. Regards Fiza
