The Difference Between

The OSI (Open Systems Interconnect) 7-layer model is based, in-part, on standards published by the IEEE (Institute of Electrical and Electronics Engineers). For example, IEEE standard 802.3 describes Ethernet. In the OSI model, the 802.3 standard exists at layers 1 and 2. ANSWER IEEE is a standards organization to which many hardware and software suppliers both contribute to and agree to use 'standardized' techniques. Ethernet is but only ONE of the many standards, and the OSI is only one of the usage standards.

CMOS is a semiconductor chip of SRAM (Static Random Access Memory); while BIOS is executable code stored in ROM.

The CMOS chip is an ultra low power memory, that can retain its data with only a simple watch type battery for a long time. Computers often store hardware configuration information in CMOS RAM.

BIOS is the programming that a computer uses during power on to get booted. It is also often the interface between the software and the hardware. BIOS used to be stored in read-only memory (ROM), and as such, was unchangeable; but more recently, BIOS is stored on an EEPROM (Electronically Erasable Programmable Read-Only Memory); this allows for the ability to upgrade the BIOS code to provide support for changes in technology, or repair bugs discovered in the older code.

BIOS = Basic Input Output System

CMOS = Complementary Metal-Oxide-Semiconductor

BIOS is the interface which is built-in to a computer system's firmware used to configure the computer system hardware in very basic ways. BIOS can be used to enable or disable hardware integrated into the motherboard such as IDE controllers, USB hosts, audio controllers, video, and more.

It is often accessed by pressing F2 during startup, but this can change from manufacturer to manufacturer.

CMOS is a type of battery often used to power the circuit which allows the information in BIOS to be stored. If the CMOS battery is drained or removed all the system configuration data in BIOS will be reset to factory defaults every time the computer is shut off. CMOS batteries are also commonly used in calculators, hearing aides, and wristwatches.

Due to the close relationship between BIOS and the CMOS battery in the computer system, the two phrases are often incorrectly used as synonyms for each other. Some users will refer to opening the BIOS menu as "going into CMOS" or replacing the CMOS battery as "fixing the BIOS battery." However, none of this is seen as grammatically incorrect in common day-to-day conversation.

Many. Basically, MPEG-1 is a compression system that focuses on storing video in a hard disk, that is to say, an "error-free" environment and only is valid for low resolution images. On the other hand, MPEG-2 not only improves the compression factor, but also enhances the capabilities of the antecessor MPEG-1. MPEG-2 can be used not only to store videos (e.g. a DVD) but also can be used for broadcasting. Today's digital television (terrestrial, cable and satellite) uses the compression and signalling of MPEG-2, adapted as international organizations (ATSC, DVB) reccomend. dmb_1

Digital traffic channels: The most notable difference between the two generations is that first generation systems are almost purely analog, where as second generation systems are digital. In particular, the first generation systems are designed to support voice channels using

FM; digital traffic is supported only by the use of a modem that converts the digital data into analog form. Second generation systems provide digital traffic channels. These readily support digital data; voice traffic is first encoded in digital form before transmitting. Of course, for second-generation systems, the user traffic (data or digitized voice) must be converted to an analog signal for transmission between the mobile unit and the base station.

Encryption:

Because all of the user traffic, as well as control traffic, is digitized in

second-generation systems, it is a relatively simple matter to encrypt all of the traffic to prevent eavesdropping. All second-generation systems provide this capability, whereas first generation systems send user traffic in the clear, providing no security.

Error detection and correction:

The digital traffic stream of second-generation systems also lends itself to the use of error detection and correction techniques. The result can be very

clear voice reception.

Channel access:

In first generation systems, each cell supports a number of channels. At

any given time a channel is allocated to only one user. Second generation systems also provide multiple channels per cell, but each channel is dynamically shared by a number of users using time division multiple access (TDMA) or code division multiple access (CDMA).

The ammount of specialization the Agent you are dealing with has in a certain area. Typically Level 1 are just normal people reading the instructions off a teleprompt, or computer screen in front of them. They are the ones who ask if the computer is plugged in or not. They are just there for basic knowledge. Level 2 is a little more specialized. Normally in the field you have a question regarding, such as Networking (the most common) or Hardware, or software. They normally have a good understanding of the field, and can help you with most tasks such as Reissuing you an I.P Address, or telling you the Default Gateway for your Router. Level 3 techies are the big dogs. They are fully specialized in a certain field. Not networking, but Broadband Network Interfacing, or something of the sort. These people are the ones who know vast ammounts of one knowledge for one VERY PARTICULAR field. They can help you do advanced things like manually setting up a DHCP Network and DNS Server, along with all of the info to register IPX Protocols within a Windows ME to Windows XP Network.

So I guess the simple answer is: The ammount of knowledge that in known for a specific field.

A stored procedure is like a miniture program in SQL Server. It can be as simple as a select statement, or as complex as a long script that adds, deletes, updates, and/or reads data from multiple tables in a database. (Stored procedures can also implement loops and cursors which both allow you to work with smaller results or row by row operations on data.) The SQL Server functions are option for doing certain operations in SQL Server. They can not be used to update, delete, or add records to the database. They simply return a single value or a table value. They can only be use to select records. However, they can be called very easily from within standard SQL, such as: SELECT dbo.functionname('Parameter1') OR SELECT Name, dbo.Functionname('Parameter1') FROM sysObjects For simple reusable select operations, functions can simply your code. Just be wary of using JOIN clauses in your functions. If your function has a JOIN clause and you call it from another select statement that returns multiple results, that function call with JOIN those tables together for EACH line returned in the result set. So though they can be helpful in simpling some logic, they can also be a performance bottleneck if they're not used properly.

In contiguous allocation there is no overhead during execution of a program. In noncontiguous allocation address translation is performed during execution Contiguous memory allocates single area of memory Noncontigious memory allocates several memory areas - one memory are to each component of a process

In a radial circuit you wire 3 cables (live/hot, neutral and earth) from the board to the first socket, and then loop these cables on from socket to socket till you get to the last socket and you are finished.

In a ring circuit, the is an additional set of cables from the last socket back to the board. This increases the load that can be put on the circuit.

In my country (Ireland) this is generally not in practice any more, and most circuits are radial circuits.

An intranet is medium of communication in a closed community.Messages from the intranet is transfered through a gateway,with a firewall along with users authenticatedand encrypted messages, which cannot be viewed by any other person that does not belong to the virtual private network. It also used only in the local Area that means information shared in between two or more blocks required.

The key difference between translation and interpretation lies within the choice of communication channel. Simply put, translation deals with written communication, while interpreting is all about the spoken word

Translators work on written documents, including books, essays, legal documents, medical records, websites, instruction manuals, subtitles for film or TV, or any other form of information in written form. Interpreters, on the other hand, are involved in projects that require live translation; for example conferences and business meetings, medical appointments and legal proceedings

Both translators and interpreters have a deep linguistic and cultural knowledge of their working languages, as well as the ability to communicate clearly and succinctly. It is, however, important to highlight the distinctive features of these two professions

Translators generally work from their home computers, and tend to specialize in a particular field. Good translators have excellent written skills and are usually perfectionists by nature, paying particular attention to the style of the source documents, as well as the accuracy and significance of the terms used within their translations

Unlike translators, interpreters do not provide a word-for-word translation; instead, they transpose spoken messages from one language into another, instantly and accurately. Interpreters work in real-time situations, in direct contact with both the speaker and the audience. They rely primarily on their linguistic expertise acquired through training and experience - a sentence in one language may be rendered an entirely different way in another. Good interpreters are endowed with very quick reflexes, as well as a good memory and speaking voice. An interpreter is often more than an on-demand translator, however - they also act as a facilitator between speaker and listener, both linguistically and diplomatically

A toggle switch is like a light switch. You flick (or 'toggle') the switch on or off and it stays in that position until you flick it again.

You could compare a push button switch to a key on a keyboard. When you press a key momentarily it will display one letter on the screen. If you hold down the key, the same letter will repeat (e.g. aaaaaaaaaaaaaaa).

Toggle switches can also look like push button switches. Most power buttons on a desktop computer tower is a toggle switch. The reset button on a computer tower is a push button switch.

A P4 processor is fast, but the Pentium D is much faster. The D stands for Dual Core. This means that they have two on die processor cores instead of just one, as the Pentium 4 does. Two processors also makes it better for "demanding" applications.

The Pentium D is better if you have a motherboard that will utilize the technology. As stated the Pentium D is Duel core. This is Intel's way of creating the closest environment of a true duel processor. The HT is for Hyper-Threading which acts like a zipper and allows several applications to process at the same time. The Pentium D will really make a difference when used with the new 64 bit operating system.

However, HT (Hyper-threading) P4, does have emulated Dual Core processing. In short, the processor makes the computer think its runing a dual core. The Pentium 4 also has a couple different levels, so if you are trying to make a comparison, make sure that you look carefully.

Although neither can match the power of an Athalon or an AMD x2 processor. If you are buying, get something with 64 bit processing. WAY faster and better for games and high graphic systems.

Branded computers are manufactured by big companies like Packard Bell, Acer, Dell, Compaq, IBM, Gateway and others. These big names have built their reputation over the years. Therefore they do take quality seriously, since their reputation is at stake. Branded computers save time to the user, instead of having to assemble his own personal computer, which can be a difficult task to a non technical person.

When you buy a branded computer you are covered with a guarantee and there are less chance that something will go wrong, than if you had to assemble the computers yourself. The difference between branded and assembled computers is that while branded computers are built in mass productions plants, assembled computers are built by a technical person or by the computer owner.

When one buys a branded computer, he has a quality assurance that the computer components have been tested thoroughly. A branded company is expected to make use of quality parts and not cheap ones. This means that the computer owner gets good quality for a reasonable price. Branded computers are expected to give stable performance since all parts are manufactured by the same company, while in assembled computers one can experience hardware conflicts and other technical problems.

The buyer also enjoys experienced technical support from the mother company, while if you buy an assembled computer you are at the mercy of the after sales service of the shop keeper. Another advantage of a branded computer is that it looks unique in design and professional. Branded computers contain original software such as operating system and common applications. Even extended warranties are available. Branded computers come with PC restore CD.

First the dictionary meaning of these two words:

Device: A thing made for a particular purpose; an invention or contrivance, especially a mechanical or electrical one

Instrument: a mechanical tool or implement, especially one used for delicate or precision work

Device is something that is a hardware and capable of doing or supporting some sort of task.

And Instrument is something that is also a hardware but designed to do a specific task.

Packets are the data units applicable to the network layer while frames are the data units applicable to the data link layer of the OSI model. At certain points on a network, packets may be packaged into frames for easier transmission.

Mobile Communication: A communication network (either public or private) which doesn't depend on any physical connection between two communication entities and have flexibility to be mobile during communication. The current GSM and CDMA technologies offers Mobile Communication.

Bounded MediaB: Bounded media are the physical links through which signals are confined to narrow path. Bounded media are made up of a external conductor(usually copper) bounded by jacket material. These are also called guided media.
