ANSI is the acronym for the American National Standards Institute. This institute creates standards for a wide variety of industries, including computer programming languages. ANSI standards currently exist for vast numbers of such seemingly unrelated items as refrigerators, industrial carpet, mayonnaise, and computer parts, among others.

SCSI (pronounced "scuzzy," not "sexy") stands for small computer systems interface. SCSI is a standard for interfacing, or connecting, personal computers to peripheral devices (like scanners, hard disks, or CD-ROM players) and having them send information to each other.

Application Program

Application Program: Applications programs are programs written to solve specific problems, to produce specific reports, or to update specific files. A computer program that performs useful work on behalf of the user of the computer (for example a word processing or accounting program) as opposed to the SYSTEM SOFTWARE which manages the running of the computer itself, or to the DEVELOPMEN software which is used by programmers to create other programs.

These spoonfuls of alphabet-number soup designate different standards for connecting serial devices (like modems, mice, and printers) to the computer by plugging their cables into serial ports. Through a serial port, the computer exchanges information with the device back and forth "serially," or one bit at a time.

(Multiple-instruction multiple-data) A generic description that can be applied to any MULTIPROCESSOR computer architecture in which each processor is able to execute a different program, as distinct from a SIMD architecture in which each processor executes the same program on a different data item. With MIMD architecture, the deployment of the program code onto the different processors and the interconnection TOPOLOGY of the processors become visible to the programmer, and complicate the writing of programs.

There are several varieties of computer programs, but the ones most of us are familiar with are the application software. An application is software with a specific use, such as writing, dealing with numbers, organizing large amounts of data, etc. Popular types of applications software include word processors, database managers, spreadsheets, graphics applications, money managers, and games. Other types of computer software include utilities (programs designed to tune the performance of the computer), and system software (basic programs, such as DOS , windows ,UNIX , Linux , MAC which are required to operate the PC).

Clock speed refers to how fast the system clock drives the computer's CPU (central processing unit, the chip that runs the computer) which determines how fast the system as a whole can process information internally. Clock speed is measured in megahertz; a speed of one megahertz (l MHZ) means the system clock is sending out its electric current one million times per second. The higher the clock speed of a computer, the faster the computer can operate, assuming all other factors are equal. However, clock speed isn't the only factor that determines your computer's overall performance, or even how fast the microprocessor (another term for the cpu) gets things done. Two different microprocessors may run at the same clock speed, and still take different amounts of time to finish a given job.

A trackball is an alternative to a mouse or a stylus. It looks kind of like a mouse upside-down, and you use it by rolling the ball around with your fingers. It has one or more buttons to click, just like a mouse.

Dos use the acronym LPT to refer to its three printer ports: LPT1, LPT2, and LPT3. The acronym is a contraction of line printer.

ANSI.SYS (pronounced "ansee dot sis") is a driver file a little software module, or controller used by MSDOS and OS/2, ANSI.SYS tells the computer how to display information based on the standard codes adopted by the American National Standards Institute (ANSI). Each code in the ANSI table represents either a character (like the letter S) or a number (such as the number 5), and other keys found on the keyboard (such as the Enter key). Some codes in the table are not found on the keyboard, but programs use them for specific purposes (such as making the PC beep, or moving the cursor to the next line on-screen).
