Brief And Objective Review About Netbook computers Computers Articles | December 31 Wholesale Cheap Baseball Jerseys , 2011 Netbook computers can be described as a smaller version of laptops. They have all the features and characteristics of a laptop except that they are smaller in size, lighter in weight and thus more portable.
Netbook computers are designed in order to meet and fulfill the needs of the modern career person, traveler, business person, student or any other person that wants to access the internet anywhere anytime.?
?
?The netbook computers allow the users to browse the internet, check, compose and send emails Wholesale Baseball Jerseys , listen to music, chat on Facebook, Tweet on Twitter and perform several other activities on these small devices.? The portable functionality is what makes the netbook computers very popular.?
?
Most netbook computers have a LED TFT LCD display screen of 12.1 inches. LED is an abbreviation of Light Emitting diodes; TFT means Thin Film Transistor and LCD means Liquid crystal display. These three are the most modern display platforms and they ensure that you get clear pictures and videos of very high resolution.
?
Despite their very many common features, netbook computers may vary in terms of cost, performance, durability, shape Wholesale MLB Jerseys From China , color, design, etc. If you want to acquire a device that will serve the intended purposes very well you should be very wise in your choice.
?
Research about netbook computers is very important if you want to learn the pros and cons of every brand, model and type in the market.? In all cases, you should not base your buying decision on the price factor only.
?
You should consider the cost of the netbook against the following other vital features and characteristics that are equally important.
?
The most vital factors to consider in choosing netbooks
?
SPEED: ?the speed of netbook computers is determined in terms of one million cycles in only one second.? The standard measurement units for computer speed are the GHz (read Giga Hertz) or MHz (Mega Hertz). 1 GHz is equivalent to 1,000 MHz.? Most netbook computers in the market have a speed of 1.66 GHz. A netbook with higher GHzMHz is better because it executes commands faster.
?
RAM and HDD: the Random Access Memory (RAM) refers to the ability of computer to store information.? The Hard Disk Drive is another form of computer that lets you store music, files Wholesale MLB Jerseys China , folders, movies, operating systems, etc.
?
Mostnetbook computers have a RAM of 2 GB but the HDD differs. Some may have HDD of 160 GB, others 250, others 320 and so on.? You should choose the net book that has higher RAM and higher HDD because it is capable of storing a lot of files, data Wholesale Throwback MLB Jerseys , music, videos, etc
?
Other important things to consider include US port hubs, Screen display size (the higher the better) Battery, color and finally the price.?
To pass the Network+ exam, you must know the differences and similarities when it comes to hubs, repeaters, and bridges. Learn these important details from Chris Bryant, CCIE #12933.
To pass your Network+ certification exam, you must know the differences between hubs Wholesale Authentic MLB Jerseys , repeaters, bridges, and switches. The differences are straightforward for the most part, so let's examine the basic purpose of these devices.
Hubs and repeaters both work at the Physical layer of the OSI model. They do not help to direct traffic toward the proper destination, as routers and switches do. Their purpose in the network is simply to make the signal strong enough to reach its destination, by regenerating the signal. Hubs and repeaters both take an incoming data signal and make a clean, strong copy of the signal. Otherwise Wholesale Cheap MLB Jerseys , the signal would suffer from attenuation, the gradual weakening of a signal as it gets farther and farther away from the source.
Repeaters are just about extinct in today's networks, because they only have one input port and one output port. Naturally, this means we could only regenerate a single data signal. Hubs are really just multiport repeaters, but their multiple ports give them some value in today's networks.
By using a hub to connect hosts, we're left with one collision domain. Any data sent by these hosts is subject to colliding with data sent by another host. We'll talk more about collision domains in another CompTIA tutorial, but keep in mind that hubs do not break them up.
Using a hub also results in one broadcast domain Wholesale MLB Jerseys , since a broadcast sent by any of these hosts will be heard by all other hosts.
Bridges and switches work at the Data Link layer of the OSI model, making them "Layer Two" devices. Both read MAC addresses to create a MAC address table, which allows the switches to help send frames to their proper destination. You see very few bridges in today's networks, especially with the advent of Layer Three switches.
It's not that bridges are bad at their job, it's just that switches are better. They can operate at higher speeds and offer more options, especially now that many new switches can perform routing as well as switching. (Layer Three switches used to be called brouters, but as the usage of bridges has faded Wholesale Jerseys From China , so has the use of this term.)
