Harvard Referencing
Pencantuman referensi diperlukan untuk setiap tulisan ilmiah yang dibuat oleh para akademis,
termasuk di dalamnya pelajar dan mahasiswa. Tujuan dari pencantuman ini untuk membuktikan
kebenaran sumber informasi dan menjaga kredibilitas penulis yang bersangkutan. Referensi juga
menunjukan bahwa isi tulisan dapat dipertanggung-jawabkan dan bukan hasil penjiplakan karya
orang lain. Dengan mereferensikan sumber informasi, seorang penulis telah membuktikan bahwa
dia seorang akademis yang berintegritas dan dapat dipercaya.
Panduan ini dibuat untuk membantu para akademis dalam mereferensikan sumberinformasi dalam tulisannya. Model referensi yang digunakan adalah model Pengarang-T(Author-Date) atau yang lebih populer dengan nama sistem referensi Harvard. Sistem Harvard telah dipergunakan secara luas di lingkungan akademis di seluruh dunia, dan panduan ini diharapkan dapat mempermudah para penulis dalam mempergunakan sistem referensi tersebut.

What is a Computer?
A computer allows users to store and process information
quickly and automatically.
A computer is a programmable
machine. It allows the user to store all
sorts of information and then ‘process’ that information, or data, or carry out
actions with the information, such as calculating numbers or organising words.
Computer: A machine that can receive and store
information and change or process it.
Information: Knowledge
that is communicated.
Data (pl.): The representation of information in a formalised manner
suitable for communication, interpretation and processing, generally by a
computer system. Note: the term ‘raw data’ refers to unprocessed information.
Computers can be generally
classified by size and power, although there can be considerable overlap. Following are descriptions of several
different types of computers.
Mainframe
computers are large-sized, powerful multi-user computers that can support
concurrent programs. That means, they
can perform different actions or ‘processes’ at the same time. Mainframe computers can be used by as many as
hundreds or thousands of users at the same time. Large organisations may use a mainframe
computer to execute large-scale processes such as processing the organisation’s
payroll.
Mini-computers
are mid-sized multi-processing computers.
Again, they can perform several actions at the same time and can support
from 4 to 200 users simultaneously. In
recent years the distinction between mini-computers and small mainframes has
become blurred. Often the distinction
depends upon how the manufacturer wants to market its machines. Organisations may use a mini-computer for
such tasks as managing the information in a small financial system or
maintaining a small database of information about registrations or
applications.
Workstations are powerful, single-user
computers. They have the capacity to
store and process large quantities of data, but they are only used by one
person at a time. However, workstations
are typically linked together to form a computer network called a local area
network, which means that several people, such as staff in an office, can
communicate with each other and share electronic files and data.
Computer network: A grouping of computers and peripherals connected together
by telecommunications links to enable a group of users to share and exchange
information.
Networks are discussed in more detail later in this module.
A workstation is similar to a
personal computer but is more powerful and often comes with a higher-quality
monitor. In terms of computing power,
workstations lie in between personal computers and mini-computers. Workstations commonly support applications
that require relatively high-quality graphics capabilities and a lot of memory,
such as desktop publishing, software development and engineering applications.
Personal
computers (PCs), also called microcomputers,
are the most popular type of computer in use today. The PC is a small-sized, relatively
inexpensive computer designed for an individual user. Today, the world of PCs
is basically divided between IBM-compatible and Macintosh-compatible machines,
named after the two computer manufacturers.
Computers may be called ‘desktop’ computers, which stay on the desk, or
‘laptop’ computers, which are lightweight and portable. Organisations and individuals use PCs for a
wide range of tasks, including word processing, accounting, desktop publishing,
preparation and delivery of presentations, organisation of spreadsheets and
database management. Entry-level PCs are
much more powerful than a few years ago, and today there is little distinction
between PCs and workstations.
What are the Components of a Computer?
Computers are made
up of two parts: the hardware and the software.
Hardware: The physical equipment required to create, use,
manipulate and store electronic data.
Software: The computerised instructions that operate a
computer, manipulate the data and execute particular functions or tasks.
All computers
require the following hardware components:
·
central processing unit (CPU)
Central processing unit (CPU): The chip or chips at the heart of a computer
that enable it to process data. Also known as a processor.
·
memory
Memory: An area within a computer system that holds data waiting to be processed.
·
storage device
Storage device: The place where a
computer puts data.
·
input devices : the devices that allow
data and instructions to enter a computer (such as a keyboard, mouse, scanner)
Input: Any resource required for the functioning of a process, in the
course of which it will be transformed into one or more outputs.
·
output devices: the devices that allow information to be represented (that is, given
out) to the user, such as a display screen or printer)
Output: The product of the transformation of inputs by a process.
Printers,
scanners and external disk drives that may be connected to the computer are
also sometimes called ‘peripheral devices’.
Peripheral device: Any piece of equipment in a computer system that is not
actually inside the computer itself.
The central
processing unit (CPU) is the heart of the computer. It carries out all of the instructions given
in a program, such as a word processing or spreadsheet program. The CPU consists of one or more chips
(another name for “integrated circuits”).
Chip: A
small piece of semi-conducting material (such as silicon) about 1 centimetre (¼
inch) square on which an integrated circuit is embedded. An integrated circuit is a number of
electronic components joined together to form a path for electricity. Central processing unit chips contain the
circuits representing the CPU.
A microprocessor is a particular type of chip. The original IBM personal computer used the
Intel 8088 microprocessor. Most of
today’s microcomputers are designed around a microprocessor from one of two
product families: x86 or Power. The
80286, 80386, and 80486 models that followed were referred to by the last three
digits, 286, 386, and 486. For the next
generation, however, Intel broke with tradition and introduced the Pentium in
1993. In 1997, it introduced the Pentium
II to address multi-media applications, and most recently the Pentium III to
address the new opportunities provided by access to large volumes of
information on the world wide Web. Other
manufacturers of chips (such as Cyrix) produce chips of similar power and
capabilities.
CPU’s are not all equal. Some process data faster than others. A computer contains a system clock that emits
pulses to establish the timing of all systems operations. The system clock operates at a speed quite
different from a clock that keeps track of the time of the day. The system clock determines the speed at
which the computer can execute an instruction, and therefore limits the number
of instructions the computer can complete within a specific amount of
time. The time to complete an
instruction execution cycle is measured in megahertz (MHz) or millions of
cycles per second. Although some
instructions require multiple cycles to complete, the processor speed should be
thought of in terms of the number of instructions the processor can execute in
one second. Today, microprocessor speeds
exceed 300 MHz. If all other
specifications are identical, then higher megahertz ratings means faster
processing.
When determining what type of
computer you are using or considering what type of computer to acquire, it is
important to know that these terms – 286, 386, 486, Pentium – refer to the type
of processor in the computer. Newer computers
will come with Pentium microprocessors (or the equivalent from other
manufacturers); older ones with microprocessors from the x86 family.
It is important to know the type
of processor in your computer. Some
newer computer programs will not run on older processors, and some newer
processors are too sophisticated for older software.
The faster the processor in a computer, the more quickly
the computer will perform operations.
The most common type of memory
that most users are familiar with is ‘main memory’ or ‘RAM’ (random-access
memory).
Random access
memory (RAM): An area in the computer system
unit that temporarily holds a user’s data, operating system instructions and
program instructions.
The word ‘main’ is used to
distinguish it from external mass storage devices such as the hard drive or
disk drives. Note
that the term ‘mass storage’ refers to various techniques and devices for
storing large amounts of data; mass storage is distinct from memory because it
retains data even when the computer is turned off. Thus mass storage is sometimes referred to as
‘auxiliary storage’. Following are
definitions of common storage devices:
Storage: The area within a computer system where data
can be left on a longer term basis while it is not needed for processing.
Diskette. A small, removable, flexible mylar plastic disk covered with a thin
layer of a magnetisable substance, onto which digital data can be recorded and
stored. Also known as a floppy disk.
Hard drive: The storage area within the computer itself, where megabytes of
space are available to store bits of information. Also known as a hard disk.
Optical disk: A storage device that uses reflecting surfaces and laser technology
to read and write data on a disk. Also
known as a laser disk.
Magnetic tape: A continuous plastic strip covered with magnetic oxide; the tape is
divided into parallel tracks onto which data may be recorded by selectively
magnetising parts of the surface, or spots, in each of the tracks. The data can then be stored and reused.
How Does a Computer Work?
A computer functions
in the following manner:
·
The computer accepts input. Computer
input is whatever is entered or fed into a computer system. Input can be supplied by a person (such as by
using a keyboard) or by another computer or device (such as a diskette or
CD-ROM). Some examples of input include
the words and symbols in a document, numbers for a calculation, instructions
for completing a process, pictures, and so on.
·
The computer performs useful operations, manipulating the data
in many ways. This manipulation is
called processing. Examples of
processing include performing calculations, sorting lists of words or numbers,
modifying documents and pictures according to user instructions, and drawing
graphs. A computer processes data in the
CPU.
Process:
A systematic series of actions a computer uses to manipulate data.
·
The computer stores data. A computer must store data so that it is
available for processing. Most computers
have more than one location for storing data (the hard drive or C:\, and the floppy drive or A:\). The place where the computer stores the data
depends on how the data is being used.
The computer puts the data in one place while it is waiting to be
processed and another place when it is not needed for immediate
processing. The storage of data in the
computer is called ‘online storage’ while the storage of data on computer
tapes, diskettes or CD‑ROMs is called ‘offline storage’.
·
The computer produces output. Computer output is information that has been
produced by a computer. Some examples of
computer output include reports, documents, music, graphs, and pictures. Output can be in several different formats,
such as paper, diskette, or on screen.
A computer receives data as input, processes it, stores
it and then produces output.
