Server RAM is slower than the Desktop Ram. The desktop RAM is built for speed however the server RAM is optimized for Crash resistance and loss of data.
The Server RAM usually contains ECC – Error Correcting Code. ECC also commonly called EDAC protected memory helps correct parity errors which makes ECC RAM less vulnerable to loss of data, data corruption and possibility of a crash. This makes Server RAM much safer. Due to the implementation of ECC, these RAMs are a bit slower than their Desktop counterparts and are pretty expensive too.
On the other hand, Desktop RAMs are manufactured for speed. These RAMs neither have ECC nor are they compatible. Hence Desktop RAMs are faster than a Server RAM however, prone to crash or data loss when subjected to higher amounts of stress. ECC Memory would not be supported by Desktop Motherboards and the BIOS. Hence it is advisable to check if your motherboard and BIOS supports one if you are planning to make your desktop into a server.

The Risk of Social Networks
In the last few years daily internet users been increased significantly. Online social networking sites is the main cause for spend more time online in the day in personal lives. Obviously these have opened up new opportunity to share knowledge, ideas and common interest in a way that would otherwise be impossible.
However, openly sharing details our personal lives in online can evolve potential security risk. Although these details may seem harmless, easily any one can make life significantly for identity fraudsters being able to find a date birth, full name, home address, contact no’s on an online profile. This allows any fraudsters easily set up a credit card in someone else’s name and use it for any kind of fraud stated works.
As a good practice social networking users should not appear their full names, phone numbers, addresses and family member’s details. If someone really wanted to do it share only with the friends know well personally instead of public for everyone

Ethernet, Fast Ethernet and Gigabit Ethernet
Ethernet is a very common method of networking computers in a LAN using copper cabling. Capable of providing fast and constant connections, Ethernet can handle about 10,000,000 bits per second and can be used with almost any kind of computer.
While that may sound fast to those less familiar with networking, there is a very strong demand for even higher transmission speeds, which has been realized by the Fast Ethernet and Gigabit Ethernet specifications (IEEE 802.3u and IEEE 802.3z respectively). These LAN (local area network) standards have raised the Ethernet speed limit from 10 megabits per second (Mbps) to 100Mbps for Fast Ethernet and 1000Mbps for Gigabit Ethernet with only minimal changes made to the existing cable structure.
The building blocks of today's networks call out for a mixture of legacy 10BASE-T Ethernet networks and the new protocols. Typically, 10Mbps networks utilize Ethernet switches to improve the overall efficiency of the Ethernet network. Between Ethernet switches, Fast Ethernet repeaters are used to connect a group of switches together at the higher 100 Mbps rate.
However, with an increasing number of users running 100Mbps at the desktop, servers and aggregation points such as switch stacks may require even greater bandwidth. In this case, a Fast Ethernet backbone switch can be upgraded to a Gigabit Ethernet switch which supports multiple 100/1000 Mbps switches. High performance servers can be connected directly to the backbone once it has been upgraded.
