Transistor hookup

Industry Glossary T1 A particular designation for a fast form of connection, by phone line, to the Internet. T1 bandwidth is roughly 1. There are also Fractional T1 lines. A T1 line can send a gigabyte of information in less than 10 seconds. It has the capability of many simultaneous between hundreds and and several hundred, depending on what each connection is doing and how much of the resource they are using "conversations" or connections within.

T1 supports voice, data and video at different frequencies on the same connection. T1 is a "full time connection" as opposed to dial-up. Also known as T-1 and sometimes DS1. T1 services are the perfect solution for businesses having moderately high bandwidth needs and many users.

The European equivalent is an E1. T1c A particular designation for a fast form of connection, by phone line, to the Internet. A legitimate but rarely used broadband designation exactly twice the speed and capability of T1; a T1 is 24 voice channels or kbps while the T1c is 48 voice channels or kbps. T2 A particular designation for a fast form of connection, by phone line, to the Internet.

A legitimate but rarely used broadband designation exactly four times the speed and capability of T1; a T1 is 24 voice channels or kbps while the T2 is 96 voice channels or kbps. T3 A particular designation for a fast form of connection, by phone line but usually fiber optic , to the Internet.

It is the backbone of the Internet and of major corporation systems. T3 bandwidth is roughly 45 mbps per user with the capability of many simultaneous between hundreds and thousands, depending on what each connection is doing and how much of the resource they are using "conversations" or connections within; it can also alternatively handle voice channels. It is about 28 times the speed of a T1 line. Some companies also offer tiered T3 services which are fractional parts in 3 mbps chunks.

T3 supports voice, data and video at different frequencies on the same connection. T3 is a "full time connection" as opposed to dial-up. This technology is also known as T-3 and DS3. The European equivalent is an E3.

T4 A particular designation for a fast form of connection, by phone line but usually fiber optic , to the Internet. T4 bandwidth is roughly mbps per user with the capability of many simultaneous between hundreds and thousands, depending on what each connection is doing and how much of the resource they are using "conversations" or connections within; it can also alternatively handle voice channels. T4 supports voice, data and video at different frequencies on the same connection.

T4 is a "full time connection" as opposed to dial-up. This technology is also known as T-4 and DS4. The European equivalent is an E4. In , the Thirteenth General Conference of Weights and Measures adopted a resolution to replace the astronomical definition of the second - the second is the duration of 9,,, cycles of radiation corresponding to the transition between two hyperfine levels of the ground state of Caesium atom.

The largest problem in the computer industry. See "Wake up and smell the roses! Tapes for computers are similar to tapes used to store music. Storing data on tapes is considerably cheaper, at present than storing data on disks. Tapes also have large storage capacities, ranging from a few hundred kilobytes to several gigabytes. Accessing data on tapes, however, is much slower than accessing data on disks.

Tapes are sequential-access media, which means that to get to a particular point on the tape, the tape must go through all the preceding points. In contrast, disks are random-access media because a disk drive can access any point at random without passing through intervening points.

The reliability factor in tapes is excellent. Because tapes are so slow, they are generally used only for long-term storage and backup. Data to be used regularly is almost always kept on a disk.

Tapes are also used for transporting large amounts of data. Tapes come in a variety of sizes and formats. Tapes are sometimes called streamers or streaming tapes. Some of the types are: Half-inch 60MB to MB: Half-inch tapes come both as 9-track reels and as cartridges.

The tapes themselves are relatively cheap but they require expensive tape drives. QIC tapes are relatively inexpensive and support fast data transfer rates. Quarter-inch minicartridges are even less expensive, but their data capacities are smaller and their transfer rates are slower. They also have relatively slow data transfer rates. DAT Digital Audio Tape cartridges have the greatest capacity along with 8-mm helical-scan cartridges but they require relatively expensive tape drives.

Tape drives have data capacities of anywhere from a few hundred kilobytes KB to several gigabytes GB. Their transfer speeds also vary considerably. Fast tape drives can transfer as much as 20MB megabytes per second. The disadvantage of tape drives is that they are sequential access devices, which means that to read any particular block of data, you need to read all the preceding blocks. This makes them much too slow for general purpose storage operations.

However, they are among the least expensive and most reliable media types for making backups. TAR A program used to create a single file archive from several files, often used to distribute programs for Unix.

The Unix command has many options. As the name implies, it is a protocol for network activity. When the destination host receives a segment it sends back an acknowledgment ACK. If an ACK is not received by the source host within a certain period of time then the data is retransmitted. TCP uses sockets and ports to exchange data between applications. Ports provide a specific and universal location for message delivery, while sockets use the host IP address, port number and the type of service TCP or UDP to create a reliable connection.

TCP uses sliding windows to buffer data between hosts. A buffer that is too large or small can cause poor network performance. TD See terminal device. You can contact your local phone company for information on obtaining the equipment. TDM A telephony acronym for Time division multiplexing.

TDM systems offer a synchronous transmission of data over a fixed bandwidth channel. The most popular TDM transports are a T1 1. This transmission medium is ideal for traffic requiring a CBR transport, such as voice. This is one of the best sources of first line defense support you can obtain on any online service. Telco The local telephone service provider. A generic term for the local telephone company operator in a given area.

Usually used with device or in place of device. Any sort of telecommunications device. In most cases, because of modem technology, it is slow, awkward and requires a fair amount of equipment and technology by comparison to being on the company network to allow this function to happen. The theory of VPN s is the next generation of this technology.

Although work at the company premises does not appear to be threatened as previously indicated and forecast as a cost cutting measure, new forms of telecommunication such as voice and multimedia communication, as well as work group software are certain to make telecommuting more social and viable in the future.

Major innovations in Internet technology may well cut the anticipated time to place this trend in motion. There is no distinction between wired and wireless. The term has come to refer to all the aspects of television programming and transmission as well. The word television is a hybrid word, coming from both Greek and Latin. It is often abbreviated as TV.

Because you are going through a local provider, in this case your ISP , there are no long distance charges to pay. Bulletin boards, online stores, and multi-user games are just some of the things you can tap into using telnet.

For more information, contact your ISP. Telnet is usually used on the UNIX family of operating systems or on mid-size and up computers used as hosts. TenTime A technology of a different form of time keeping; see more details on our TenTime converter.

A number equivalent to 2 to the 40th power 1,,,, bytes. This is approximately 1 trillion in the American system bytes, or gigabytes. A number equivalent to 10 to the 12th power 1,,,, This is exactly one trillion, or billions; the inverse is pico.
