Computer Terminology

One nibble, or nybble, is equal to four bits.

Your input device, for example a mouse, is connected to your input medium, your computer.

an input device is a device that is used to input or helps to enter data into the computer and an input medium is where the input device is detected e.g the slots

It depends on what kind of model it is, but in the model for computer 321O, it is on the layer between trhe keyboard and the behind screen, and there is a button with the osi code and there says everything.

Coaxcial cable is typically a copper core cable with a shield separated by an air gap. It carries electrical signals along the center conductor relative to ground (usually the outer shield is tied to ground.

Fibre optic cable is glass strands which carrry light in the form of pulses rather than electrical currents.

Fibre carries a digital signal whilst copper (coaxial) commonly carries an analogue signal.

Both megabyte and kilobytes are common terms used for digital information. Both are multiples of the "byte" unit. Since "kilo" means 1,000 and "mega" means 1,000,000. That means that there are 1,000 kilobytes in each megabyte, so there are 250,000 kilobytes in 250 megabytes.

A pointer is a programming language data type whose value refers directly to (or "points to") another value stored elsewhere in the computer memory using its address.

The necessity of having information systems varies depending on the sector a system covers, but systems generally support operations and decisions made within organizations as well as helping with data storage and facilitating management. Information systems are used by a variety of organizations in different industries.

A bit, or binary digit, which can either be a zero or a one (or a "true" or "false" - the idea is that there are two different states). However, the smallest piece of data that can be directly accessed as a unit, on a modern computer, is a byte - usually a group of 8 bits.

Database as the name suggest is the collection of records or data that are related to each other. There are mainly three type of database network database, object oriented database and hierarchical database. Database helps in maintaining data consistency and data integrity.

1 terrabyte = 1,024 gigabytes.

3 terrabytes = 3,072 gigabytes.

0.5 terrabytes = 512 gigabytes.

512 + 3,072 = 3,584 gigas

False. What you have just described is called SOFTWARE.

Hardware is, (like in a hardware store) things that you can see and touch, made of material substances.

In computer terms, hardware consists of the box surrounding it, circuit boards, drive units, fans, plugs & cables etc.

Physically it could be a few months to a few years to a hundred years. It's a solid state device which as a general rule has a rather long lifespan.

Logically it really depends on which architecture and operating system you use. In terms of Linux probably 10+ years and Windows um yesterday unless you still use 98, 2000 and to a lesser degree XP.

In some cases, two 1gb cards will run faster as they sort of run in parallel.

However the difference is not dramatic, so it doesn't really matter either way.

each channel can only transmit signals in one direction

signals are transmitted as rf waves

can be used to transmit multiple signals at once

The sequence in memory size is * 8 bits = 1 byte * 1,024 bytes = 1 kilobyte * 1,024 kilobytes = 1 megabyte * 1,024 megabytes = 1 gigabyte * 1,024 gigabytes = 1 terabyte * 1,024 terabytes = 1 petabyte .... and we haven't yet come to need to use the next stage, which will be * 1,024 petabytes = 1 exabyte

Super Socket 7 is a slight enhancement of the Socket 7 platform created by AMD and VIA after Intel abandoned the platform. The socket itself is not distinctive; it is the chipsets used with it that set it apart from Socket 7 boards. Namely, Super Socket 7 boards run at a faster FSB speed than ones with Intel chipsets. Intel stopped at 66 MHz, but AMD and VIA pushed it up to 100 MHz.

While the convention for RAM is that 1 Gbyte = 1024 Mbytes (if your PC starts its BIOS slowly enough and you have 1 or more Gbytes of RAM then you see a figure that is evidence of this), this multiple of 1024 is peculiar to the labels Gbyte, Mbyte, and Kbyte for the number of addressable locations in memory chips used for minicomputer architecture. ...

Note that for distinct locations on a binary (base-2) storage device in a "minicomputer" architecture (which all desktops, all laptops, and most servers utilize), 10 bits are needed to address the number of locations refered to by the label "1 Kbyte" (Kilobyte) = 1024 (= 2^10) bytes (1 byte = 8 bits). The number of distinct addresses for internal RAM are increased in powers of 2 (not simply some integer number of more bytes), as adding another bit to address length increases the number of distinct locations by a power of 2. As integrated circuit (IC) chip technology progressed, a single "chip" (for minicomputer architecture with digital devices on doped silicon) of RAM eventually was manufactured having 1024 x 1024 (= 2^20) bytes which was labeled "1 Mbyte" (Megabyte). However, this labelling convention was continued ONLY FOR MARKETING REASONS when memory on RAM cards reached the Gbyte level (Gigabyte -- 1024 x 1024 x 1024 bytes -- 2^30). The first single chip of RAM that had 1 Mbyte was manufactured a considerable number of years before a 1 Gbyte RAM chip was available. (side note: cards mounting RAM chips may be called "sticks" because their length is significantly greater than their width -- looking somewhat like the shape of a stick of wood)

While IC technology has reached the point where a single chip of RAM could be manufactured having 1 Gbyte, such a chip would be more expensive, and have more formidable engineering problems (eg. much more heat from a single chip during operation) than a RAM card that has a few multi-Mbyte chips mounted on it. Hence, there is no physical basis for the convention that "1 Gbyte" is 1024 Mbytes. Also, there is convenience in reverting to a label referring to the next magnitude of 1000 times greater as used in base-10 number labeling (remember that scientific labels for measurements in multiples of 1 thousand use Kilo, 1 million use Mega, and 1 billion [10^9] use Giga).

Indeed, for desktop computers the memory cards on the market DON'T have 1 Gbyte (or more) RAM on a single chip because there is adequate space on memory cards for several mult-Mbyte chips to aggregate a few Gbytes of memory, and there is no good reason to redesign main-boards to dedicate less space per RAM socket. I suspect the main reason that small electronic consumer devices (eg. a handheld GPS device, or a smart phone) are not available with as much internal RAM (permanent part of the device, not talking removable cards here) as can be configured in a desktop computer, is that manufacturing a single memory chip for internal RAM (which would not cause immediate problems due to overheating) would require the price to be several times the level at which such devices are selling for now. Also, they might be so much more prone to overheating that the users would need to take this into consideration; continuous operation of the device for more than several minutes having a higher risk of erroneous results.

An inventory system helps to make sure that product purchased from a supplier is correctly dispensed to the customer: This cuts back on overhead, waste (where products are perishable) and can help you to minimize theft (internal and external)

It will depend on the application you are using and the version. Up to Excel 2003 .xls was used but for versions since 2007 .xlsx is used. Other spreadsheet programs use different extensions. Works uses .wks as its extension, Open Office has used .sxc and Star Office has .sdc, Quattro has .wb2 and Lotus 123 has .123 as its extension. There are many others.
