Computer Terminology

Data is stored on the hard drive. A hard drive consists of a spinning metal plate with a magnetic head directly above it that stores data on the plate magnetically as it spins.

There is also a newer technology available called a solid state drive, or SSD. These work in a similar way as a flash drive. Rather than having a physically spinning plate like a hard drive, they use microchips to store data.

Less than 1mb. There is 1024kb in a meg. 736kb is far less than 1mb.

Streaming Data

You save data by copying it from memory to your hard drive.

You back it up by copying it from your hard drive to a CD (or other removable medium).

An output is something you plug in and something comes out of it. Computer hardware equipment used to communicate the results of computer processing, carried out by an information processing system on the outside world (such as computer).

Apache

about 75 gigs

At the end of the fiscal year

There are 1024 kilobytes in a megabyte or 1/1024 megabytes in a kilobyte

The PGA socket has pins on the bottom of the package aligned in uniform rows.

The SPGA socket has pins on the bottom of the package that are staggered to squeeze more pins into a small space.

the memory that directly communicates with the CPU is called Cache Memory this is; When the processor(CPU) needs to read from or write to a location in main memory, it first checks whether a copy of that data is in the cache. If so, the processor immediately reads from or writes to the cache, which is much faster than reading from or writing to main memory. A CPU cache is a cache used by the central processing unit of a computer to reduce the average time to access memory. The cache is a smaller, faster memory which stores copies of the data from the most frequently used main memory locations. As long as most memory accesses are cached memory locations, the average latency of memory accesses will be closer to the cache latency than to the latency of main memory.

Legality- user notification that actions are being logged, conforming to legislative requirements (retention of data for what period of time).

Security - What was done by whom, logging of unneccessary data e.g. user accessed this with these credentials.

Performance - Logging too much can use lots of storage.

if u bit a dik it past if u byte a dik its present tense.

when the micros and the minis were introduced in the 1960's they differed both in their speed and storage capabilities. minis were usually used in areas where there was a need for multiple users to be logged in simultaneously but now the term minicomputer has become obsolete.

microcomputers also have different types handheld, personal digital assistant, Macintosh (MAC), Tablet, Laptop (Notebook) and desktop while minicomputers are less expensive than mainframe computers. Minicomputers are also designed for a single user only.

Central Processing Unit.

Take an R.V. the data is just the sequence of numbers. the amount of information is the intersection of the entropy between the data input and output

Your local computer supply store should be able to help you here, they could order one for you, or you could order one yourself by ordering on Gigabyte's online store

Advantages:

•Data isn't dependent on structure of the database.

•Restrict access to a database.

•Subset of data contained in a table.

•Join and simplify multiple tables into a single virtual table.

•Acts as aggregated tables, where aggregated data (sum, average etc.) are calculated and presented as part of the data.

•Gives real time data.

Disadvantages:

•Rows available through a view are not sorted and are not ordered either.

•Cannot use DML operations on a View.

•When table is dropped view becomes inactive, it depends on the table objects.

•It affects performance, querying from view takes more time than directly querying from the table

the start-up costs are high

peoples knowledge and skills are reduced due to lacl of practice

unemployment is created because computers have taken over humans jobs

when there is no electricity the computer cant operate

backups need to be created to prevent data being lost through viruses, ect.

the constant staring at the computer is bad for the operator

you need to get a storage device for the memory depending on how much memory is needed

D.C.Ms capture data. these are normaly inside thinner devices and can colect data, even through viruses. there is 2 levels. sharp and sting. sharp is faster but expencive.

Command line interface is completely command controld ,flow of program controls by giving commands. so user have to familiar with commands. a novice user can not operate a CUI environment.

In Graphical user interface user interact to a visual environment like buttons, icons, images. so it is easy to use and a novice user can operate it without pre trainig.

Most GUI operating systems provide a feature called the "clipboard". Anything you copy or cut is automatically placed in the "clipboard" storage, permitting you to later paste it into some other place. This information will remain in the "clipboard" storage until you copy or cut something else (which will replace what was previously stored), permitting you to paste the same thing in many places if you want to.

The "clipboard" storage may be in different places or use different types of data structures depending on what type of information is being stored and its size (e.g. main memory, a temporary file, a temporary folder).
