How do ZIF sockets make it easier to remove and replace the processor?
"ZIF" is an anconym for "Zero Insersion Force".
For any processor, or other integrated circuit designed for insertion into a socket, the force required to insert or remove it is proportional to the number of pins on the chip. As each pin needs a secure connection to it's socket, the force required on modern processors, having close to a thousand pins; to insert into or remove from a socket reliably and without damage; would be extremely high and would likely cause physical damage if done by hand.
A ZIF socket utilizes a clamping mechanism whereby the socket contacts can be opened using a lever. This allows a processor, with hundreds of fragile pins, to simply be dropped into the socket with no force. Then, the ZIF socket is clamped or "locked" using the lever which firmly clamps all pins tightly.
In this manner, a ZIF socket makes difficult and potentially damaging insertion or removal of a processor or other integrated circuit, a simple, easy, and safe task.
Microsoft Office 2003 & 2007 (excel and word) to be exact.
An absolute loader is the simplest type of loader scheme that fits the general model of loaders. The assembler produces the output in the same way as in the "complier and go loader" . The assembler outputs the machine language translation of the source program.
Disadvantage:
- The programmer has to specify the address to the assembler that where the program is to be loaded.
- It is very difficult to realocate in case of multiple subroutine.
- Programmer has to remember the address of each subroutine and use that absolute address explicitly in other subroutines to perform subroutine linkage
Connections inside the computer case can cause a system to appear dead or reboot itself?
I would make sure all connections are secure tightly and well connected. Also make sure all outer connections like the connection from the monitor to the box is well connected.
Maybe the RAM sticks are not sitting tightly or check the cables to the hard drive that are well connected.
How do you decide which expansion card is the video card?
The main way to tell which expansion card is the video card is to look at the plug. If it has a VGA socket, a display port socket, HDMI, etc., then you will know it is a video card. You may identify some of the chips on the card as being RAM, or you might find a fan on it, but these features are not exclusive to video cards. If that is the place where you plug your monitor, then it is a video card, unless of course you are plugging directly into the motherboard.
What is the main computing part on the PC?
The CPU (Central Processing Unit) is either a AMD or Intel processor. If you are using a desktop you will be able to locate it on the motherboard. Its under the heat sink/fan on your motherboard. Carefully remove your heat sink and you will find your cpu.
Is a fork an example of a wedge?
No, a fence is not an example of a wedge. A fence post could be a wedge if it is pointed and designed to be pounded into the ground.
I Don't get your question, my VGA port works perfectly.
It was first conceived in 1972 by Alan Kay. The first flip form laptop was built in 1982 - it was the Grid Compass 1100.
Which password would allow a user to establish a Telnet session with a Cisco device?
On user exec mode type enable.
When you are on the privilege mode type configure terminal.
Upon reaching global config mode you have to type line vty 0 4.
Inside the vty line mode type password
Please see below example:
Router>enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#line vty 0 4
Router(config-line)#password secret
Router(config-line)#exit
Router(config)#exit

What is the difference between intermediary devices and end devices?
well if you are talking about networking devices this would be the answer to your question.
^end devices usually refer to a piece of equipment that is either the source or the destination of a message on a network.
-computers, including workstations, laptops, and servers connected to a network
-network printers, Voice Over IP (voip) phones
-camera on a network, including web cams and security cameras
^intermediary devices connect the individual hosts such as
-switches
-modems
-routers
-and even firewalls can be considered an intermediary device because they analyze traffic exiting and entering a network
Note: A hub is NOT considered an intermediary device because it does not make forwarding decisions.
A computer network is defined as two or more computers connected via software and hardware so that they can communicate with each other. Ultimately, a computer network enables the exchange of data among computers.
What are the different ways a printer can be connected to a computer?
Printers are commonly connected by one of three ways
- Older printers (and some new ones) are connected by a special cable that runs from the "Parallel Printer Port" on the computer to the printer.
- Most newer printers can be connected by a special USB cable.
- Some new printers can also be connected by wireless either directly or via a router. IF ALL ELSE FAILS, READ THE INSTRUCTIONS.

What is the advantage of DMA transfer?
DMA allows devices to communicate with each other directly, instead of relying on the CPU to manage the transfers. This frees the CPU up to do other tasks, and increases system performance.
How many kilobytes roughly in an email?

What is the overall trend in secondary storage device?
The overall trend in secondary storage device is the migration from rotating magnetic discs to solid state storage. Solid state drives (SSD's) are however considerably more costly than older types of storage.
Input device vs output device?
An input device is any device that is used to provide data and control signals to an information processing system.
Examples:
* Keyboard * Mouse * Microphone * Web cam
An output device is any computer hardware equipment used to communicate the results of data processing carried out by a computer.
Examples:
* Monitor * Printer * Projectors * Speakers
What happens when you put a magnet on your computer?
Your computer uses magnetism to store information. The binary code used by your computer to transmit information at the most basic level, 1s and 0s, are stored by your computer in the form of magnetic charges. 1s are represented by magnetized bits and 0s are represented by unmagnetized bits. (8 bits make up a byte)
Due to this, putting a magnet on your computer may damage information stored in it, as well as possibly corrupting the ROM in your motherboard. ROM is the read only memory that your computer uses to know how to start up.
For these reasons and others, I would highly recommend not putting any magnets anywhere near your computer.
