"Main sockets" is referring to fuse sockets, particularly the main fuse sockets for a fuse panel.
No, but they represent a shock hazard.
An extension lead has a plug on one end and a few sockets on the other end. They are used to reach appliances that are far away from the main sockets. It is very safe to use an extension cord as long as you don't overload them.
Yes, they are.
no
Zero Insertion Force(ZIF)
Answer: Zero Insertion Force (ZIF)
zero insertion force meaning exactly what it says. the answer is zif
ZIF or "Zero Insertion Force" sockets allow the socket to open to receive the pin without pressure and then close around the pin to give a good, solid connection.

ZIF sockets refer to the term, `zero insertion force', which is to say that the part being placed in the socket will usually just `drop in' at which point, some type of clamping system is used to hold the part in place. This is especially beneficial to parts where the leads could easily be damaged or malformed.
ZIF stands for "Zero Insertion Force."There are 2 industry uses for the term ZIF ; one is in motherboard CPU sockets, the other is for ultraportable harddrives, like used in netbooks and notebooks.Most types of CPU sockets are ZIF sockets. There is generally a lever which can be activated to release the pins of the CPU from the socket and allow it to be inserted or removed without damage. There is no single connection ZIF connection, it is merely a concept in connections, with a different layout for different types of chips.ZIF, for harddrives is an ultra-thin ribbon cable with a rigid end that slides into the harddrive connector. Most ZIF drives so far are PATA command set and are physically 1.3" or 1.8" drives.There are converters available to use CompactFlash cards in ZIF slots, and there are converters available to use ZIF PATA harddrives in 2.5" and 3.5" PATA devices.PATA stands for "Parallel Advanced Technology Attachment" as opposed to the other common ATA standard SATA, which is serial instead of parallel. PATA is a 40-pin data connector used for hard drives, cdrom/dvd drives, and other types of integrated data storage.SATA does not use a ZIF Connector (so far) , for micro-sized devices like 1.3" and 1.8" and even 2.5" harddrives , they use something called MicroSATA, which puts all 13 pins of SATA cables on a thin card-edge connector.
Preventing the motherboard from touching the case are stand-offs.
The lever doesn't lift the processor out of the socket; it takes the shearing force off of the processor pins inside of the holes, so that the processor can be lifted out, or inserted, with no pressure necessary. When you lower the lever on a ZIF socket, the pins are clamped down on under the socket plastic housing.
zero insertion force sockets (see page 178 in A+ Guide to Managing and Maintaining Your PC) "PGA, SPGA, and LGA sockets are all square or nearly square. So that even force is applied when inserting the processor in the socket, all current processor sockets have a lever on the side of the socket. These sockets are called zero insertion force (ZIF) sockets, and this lever is used to lift the processor up and out of the socket. Push the lever down and the processor moves into its pin or land connectors with equal force over the entire housing."
No. Use dielectric (silicon) grease.
