How were stone cannon balls made?
Stone canon balls, or shot, were made by hand by an experienced stonemason. The process was, and still is (can be made for living history demos but not fired ), a time consuming job. Material would have been any hard natural stone that was available, usually sand stone but sometimes granite. The stone would be hand worked to small radius sections and then rubbed up with a stone block. A reverse section template would be used for accuracy.
Idle value refers to something that is inactive or not working. It may also refer to an individual that is unemployed.
In 1939, Luther Simjian patented an early and not-so-successful prototype of an ATM.
However, some experts have the opinion that James Goodfellow of Scotland holds the earliest patent date of 1966 for a modern ATM, and John D White (also of Docutel) in the US is often credited with inventing the first free-standing ATM design. In 1967, John Shepherd-Barron invented and installed an ATM in a Barclays Bank in London. Don Wetzel invented an American made ATM in 1968.
However, it wasn't until the mid to late 1980s that ATMs became part of mainstream banking.
Why are people afraid of new technology?
For millions of years human beings have feared what they do not understand. New Technology is understood by most people and used responsibly by most people. There will always be those people who do not want to learn about new technology

How can you combine two PDFs into one?
There are many tools available on many platforms that can take care of this task. For Windows, PDFill PDF Tools is free and can accomplish this task. Adobe Acrobat (not Adobe Reader) can do it as well, but there is a cost associated with that software. There is even some application software such as Adobe ColdFusion or PHP which have methods for combining PDFs, if you need to integrate that functionality into your web site.
It simply means to enter data, in what context do you mean?
How does a digital video security system work?
It will capture and save videos for security purposes. Usually the captured pictures or videos are connected directly to the central office.

Name the various types of multiplexing techniques?
Multiplexing techniques vary widely based on what is being multiplexed. Modern telecommunications use a very wide array of techniques including:
TDM - examples: TDMA, T-carrier
FDM - examples: DWDM
Spatial - example: MIMO
Code division - examples: CDMA
Phase or polarization division - cable/satellite TV
Statistcal - examples: packet mode (STS), FHSS etc etc.
This is far from a complete list. I think the question needs to be more specific.
What job does a buzzer do in a curcit?
Buzzers in a circuit create a warning and to see if the circuit is running or not.
What is a record on a computer?
your probably thinking of a time stamp, a time stamp is meta data that retains information for files and folders such as date accessed, modified, number of files in a folder, user permissions etc... but even if you delete a file/folder it really isn't gone the only thing that happens is your computer simply changes its inode entry to 0 which can be recovered with forensic programs the only way to truly remove it is wiping it at least 7 times or more even though its always there after that it just makes it a little harder to recover it.
What roles do various protocols play on the internet?
Best written explaination is from:
http://www.edrawsoft.com/Network-Protocol.php
Types of Network Protocols
The most common network protocols are:
Ethernet
Local Talk
Token Ring
FDDI
ATM
Types of Network Protocols
Ethernet
The Ethernet protocol is by far the most widely used. Ethernet uses an access method called CSMA/CD (Carrier Sense Multiple Access/Collision Detection). This is a system where each computer listens to the cable before sending anything through the network. If the network is clear, the computer will transmit. If some other node is already transmitting on the cable, the computer will wait and try again when the line is clear. Sometimes, two computers attempt to transmit at the same instant. When this happens a collision occurs. Each computer then backs off and waits a random amount of time before attempting to retransmit. With this access method, it is normal to have collisions. However, the delay caused by collisions and retransmitting is very small and does not normally effect the speed of transmission on the network.
The Ethernet protocol allows for linear bus, star, or tree topologies. Data can be transmitted over wireless access points, twisted pair, coaxial, or fiber optic cable at a speed of 10 Mbps up to 1000 Mbps.
Fast Ethernet
To allow for an increased speed of transmission, the Ethernet protocol has developed a new standard that supports 100 Mbps. This is commonly called Fast Ethernet. Fast Ethernet requires the use of different, more expensive network concentrators/hubs and network interface cards. In addition, category 5 twisted pair or fiber optic cable is necessary. Fast Ethernet is becoming common in schools that have been recently wired.
Local Talk
Local Talk is a network protocol that was developed by Apple Computer, Inc. for Macintosh computers. The method used by Local Talk is called CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance). It is similar to CSMA/CD except that a computer signals its intent to transmit before it actually does so. Local Talk adapters and special twisted pair cable can be used to connect a series of computers through the serial port. The Macintosh operating system allows the establishment of a peer-to-peer network without the need for additional software. With the addition of the server version of AppleShare software, a client/server network can be established.
The Local Talk protocol allows for linear bus, star, or tree topologies using twisted pair cable. A primary disadvantage of Local Talk is speed. Its speed of transmission is only 230 Kbps.
Token Ring
The Token Ring protocol was developed by IBM in the mid-1980s. The access method used involves token-passing. In Token Ring, the computers are connected so that the signal travels around the network from one computer to another in a logical ring. A single electronic token moves around the ring from one computer to the next. If a computer does not have information to transmit, it simply passes the token on to the next workstation. If a computer wishes to transmit and receives an empty token, it attaches data to the token. The token then proceeds around the ring until it comes to the computer for which the data is meant. At this point, the data is captured by the receiving computer. The Token Ring protocol requires a star-wired ring using twisted pair or fiber optic cable. It can operate at transmission speeds of 4 Mbps or 16 Mbps. Due to the increasing popularity of Ethernet, the use of Token Ring in school environments has decreased.
FDDI
Fiber Distributed Data Interface (FDDI) is a network protocol that is used primarily to interconnect two or more local area networks, often over large distances. The access method used by FDDI involves token-passing. FDDI uses a dual ring physical topology. Transmission normally occurs on one of the rings; however, if a break occurs, the system keeps information moving by automatically using portions of the second ring to create a new complete ring. A major advantage of FDDI is speed. It operates over fiber optic cable at 100 Mbps.
ATM
Asynchronous Transfer Mode (ATM) is a network protocol that transmits data at a speed of 155 Mbps and higher. ATM works by transmitting all data in small packets of a fixed size; whereas, other protocols transfer variable length packets. ATM supports a variety of media such as video, CD-quality audio, and imaging. ATM employs a star topology, which can work with fiber optic as well as twisted pair cable.
ATM is most often used to interconnect two or more local area networks. It is also frequently used by Internet Service Providers to utilize high-speed access to the Internet for their clients. As ATM technology becomes more cost-effective, it will provide another solution for constructing faster local area networks.
Gigabit Ethernet
The most recent development in the Ethernet standard is a protocol that has a transmission speed of 1 Gbps. Gigabit Ethernet is primarily used for backbones on a network at this time. In the future, it will probably be used for workstation and server connections also. It can be used with both fiber optic cabling and copper. The 1000BaseTX, the copper cable used for Gigabit Ethernet, is expected to become the formal standard in 1999.

How many words per minute can a teacher type?
Obviously, the number of words one can type per minute varies GREATLY. This is all on how skilled a person is. 40 WPM is average, 60+ is good, 80-100 is professional, and over 100 is elite. Of course, these are MY standards.

What is the role of a neutral wire?
The real purpose of neutral is grounding. In order for electricity to flow you need a direct continuous link from the supply to a ground. Without the neutral electricity wouldn't be able to flow because it wouldn't have a ground (a place to go). The real name for neutral is the grounded conductor, and what is commonly referred to as ground is really the grounding conductor. The grounding conductor exists for the sole purpose of being a back up neutral in case something happens, this way you don't BECOME the ground if you touch it. But don't think that means you can go touching wires if you don't know what your doing cause you can still get hurt even with both grounded and grounding hooked up.
Your question is 'are you'.
Do you mean are 'we' dependent upon technology?' philosophically as in' the world'?
Yes, when Paleolithic Man picked up his first rock and identified a use for it, we've been dependent since that moment.
