A high-level programming language is a
programming language with strong
abstraction from the details of the computer.
In comparison to low-level programming
languages, it may use natural language
elements, be easier to use, or may automate
(or even hide entirely) significant areas of
computing systems (e.g. memory
management)
In computer science, an interpreter
normally means a computer program that
executes, i.e. performs, instructions written
in a programming language
A compiler is a computer program (or set of
programs) that transforms source code
written in a programming language (the
source language) into another computer
language (the target language, often having
a binary form known as object code). The
most common reason for wanting to
transform source code is to create an
executable program.
Data Types
Analysis is the process of breaking a
complex topic or substance into smaller
parts to gain a better understanding of it.
Fact Finding is the main process of
system analysis
Fact Finding Techniques
 To study any system the analyst needs to do collect facts and all
relevant information. the facts when expressed in quantitative form are
termed as data. The success of any project is depended upon the
accuracy of available data. Accurate information can be collected with
help of certain methods/ techniques. These specific methods for
finding information of the system are termed as fact finding
techniques. Interview, Questionnaire, Record View and Observations
are the different fact finding techniques used by the analyst. The
analyst may use more than one technique for investigation.
Interview
This method is used to collect the information from groups or individuals.
Analyst selects the people who are related with the system for the interview. In
this method the analyst sits face to face with the people and records their
responses. The interviewer must plan in advance the type of questions he/ she
is going to ask and should be ready to answer any type of question. He should
also choose a suitable place and time which will be comfortable for the
respondent.
Questionnaire
It is the technique used to extract information from number of people.
This method can be adopted and used only by an skillful analyst. The
Questionnaire consists of series of questions framed together in logical
manner. The questions are simple, clear and to the point. This method
is very useful for attaining information from people who are concerned
with the usage of the system and who are living in different countries.
The questionnaire can be mailed or send to people by post. This is the
cheapest source of fact finding.
Record View
The information related to the system is published in
the sources like newspapers, magazines, journals,
documents etc. This record review helps the analyst to
get valuable information about the system and the
organization.
Sitting With Peoples
 Sitting with various people to observe how the job is
done at the movement.
Computer Aided Learning (CAL)
/ E-learning
E-learning is the computer and network-enabled transfer of skills and
knowledge. E-learning applications and processes include Web-based learning,
computer-based learning, virtual education opportunities and digital
collaboration. Content is delivered via the Internet, intranet/extranet, audio or
video tape, satellite TV, and CD-ROM. It can be self-paced or instructor-led and
includes media in the form of text, image, animation, streaming video and audio.
Computer-aided design (CAD)
Computer-aided design (CAD),also known as
computer-aided drafting (CAD) or
computer-aided design and drafting
(CADD), is the use of computer systems to assist
in the creation, modification, analysis, or
optimization of a design. Computer-aided
drafting describes the process of creating a
technical drawing with the use of computer
software.
Computer-aided manufacturing
(CAM)
Computer-aided manufacturing (CAM) is
the use of computer software to control
machine tools and related machinery in the
manufacturing of work pieces.
