Review
The design is almost same as that of the older think pads. Athough it has a 6 - cell batter and an 8x-DVD burner, it weighs 3.5 lbs lesser than the others. The X301’s exterior is a more squarish shape and has a mettalic black finish. Just like X300, the dimensions are the same and the sides are also tapered.The dimensions are 12.5 x 9.1 x 0.9.
The thinkpad has a lower performance when compared with it’s graphic tests.
The ThinkPad X301 has achieved a score of 3157 in the PCMark Vantage, which is 400 points higher than most ultraportables. It’s a great score, but still falls about 60 points shy of the Sony VAIO VGN-Z530N’s and almost 500 points shy of the Lenovo ThinkPad X200.

Gmail has recently launched the multiple panes system, which as per the name helps you to use simoltaneously any number of panes in Gmail instead of opening a new tab.This not only makes Gmail a lot more efficient, but also makes it unique from all other mail services present in the internet.
This mew system has really helped people who often sort their mails using Labels, which earlier used to size the whole window. But now, you can view and work with more than one mail at one time.
How to enable multi-pane system?
There are only 3 steps to activate this system
- First activate Gmail labs for your account.
- After scrolling down a while you will find an option called “Multiple Inboxes”. - Enable it.
- Then setup your panes by going to Gmail settngs and select “Multiple Inboxes”. Then make upto 5 panes. For creating a pane you will have to enter the label code like “label:books” through which you can create a list of messages that are tagged with the books label. But, the best feature is that you can also combine multiple panes into a single one.

A protocol means the rules that are applicable for a network. Protocol defines standardized formats for data packets, techniques for detecting and correcting errors and so on.
To understand the concept of a communication protocol, let us assume that A and B need to talk to one another. They want to exchange their ideas. But it turns out that, both, A and B are egoists. They start talking again simultaneously, then pause for breath simultaneously, and then start talking again. Now imagine the confusion and chaos. To avoid it, they must follow a set of rules while talking. For instance, say first A must talk, then he/she must give B a chance to put forward his/her ideas, and so on. This common set of rules would be known zz communication protocol for A and B.
Thus for effective use of a network it must follow a standardized protocol. There are various protocols that are used in various types of networks. For example, IBM LAN software, DEC net (Digital’s family of communication protocols), TCP/IP (Transmission Control Protocol/Internet Protocol) etc.

1. Short cable length and simple wiring layout. Because there is a single common data path connecting all nodes, the linear topology allows a very short cable length to be used. This decreases the installation cost, and also leads to a simple, easy to maintain wiring layout.
2. Resilient Architecture. The LINEAR architecture has an inherent simplicity that makes it very reliable from a hardware point of view. There is a single cable through which all the data propogates and to which all nodes are connected.
3. Easy to extend. Additional nodes can be connected to an existing bus network at any point along its length. More extensive additions can be achieved by adding extra segments connected by a type of signal amplifier known as repeater.
Disadvantages of the Linear Topology
1. Fault diagnosis is difficult. Although simplicity of the bus topology means that there is very little to go wrong, fault detection is not a simple matter. Control of the network is not centralized in any particular node. This means that detection of a fault may have to be performed from many points in the network.
2. Fault isolation is difficult. In the star topology, a defective node can easily be isolated from the network by removing its connection at the center. If a node is faulty on the bus, it must be rectified at the point where the node is connected to the network.
3. Repeater configuration. When BUS type network has its backbone extended using repeaters1, reconfiguration may be necessary.
4. Nodes must be intelligent. Each node on the network is directly connected to the central bus. This means that some way of deciding who can use the network at any given time must be performed in each node.
