Difference Between CAT5 and CAT6 Cable And Connector
Yes, there is a difference. Cat6 uses thicker copper and insulation which helps in reducing near end cross talk - the CAT6 jacks are made to take this into account (the terminations are staggered on a Cat6 jack, but in a straight line on Cat5E).
Some category 6 cable designs have a spline to increase the separation between pairs and also to maintain the pair geometry. This additional separation improves NEXT performance and allows category 6 compliance to be achieved. With advances in technology, manufacturers have found other ways of meeting category 6 requirements. The bottom line is the internal construction of the cable does not matter, so long as it meets all the transmission and physical requirements of category 6. The standard does not dictate any particular method of cable construction.

Linux Filesystem Hierarchy & Probable Partition Size
Linux adheres to the Filesystem Hierarchy Standard for directory and file naming. This standard allows users and software programs to predict the location of files and directories. The root level directory is represented simply by the slash /. At the root level, all Linux systems include these directories:
Linux Partitioning for Intel x86
If you have an existing other operating system such as DOS or Windows and you want to preserve that operating system while installing Linux, you may need to resize its partition to free up space for the Linux installation. The installer supports resizing of both FAT and NTFS filesystems; when you get to the installer's partitioning step, select the option to partition manually and then simply select an existing partition and change its size.

Common Computer Hardware (Physical) and Software (Virtual/Logical) Ports
In computer hardware, a port serves as an interface between the computer and other computers or peripheral devices. Physically, a port is a specialized outlet on a piece of equipment to which a plug or cable connects. Common computer hardware ports include -
What Is Thin Client?
A thin client (sometimes also called a lean or slim client) can refer to either a software program or to an actual computer that relies heavily on another computer to do most of its work. A thin client is part of a network, and the client software or computer acts as an interface, while the network server computer does all the real work. In the case of a computer, a thin client is unable to perform many functions on its own. A thin client computer may be a machine designed only for online use, sending and receiving email, and surfing the net.
