SERVANT BUT
A DANGEROUS MASTER.”
Christian lous lange
is a device that accepts information (in the form of digitalized data) and manipulates it for some result based on a program, software, or sequence of instructions on how the data is to be processed.
Computer
Three principal characteristics of computer
- It responds to a specific set of instructions in a well-defined manner.
- It can execute a pre-recorded list of instructions.
- It can quickly store and retrieve large amounts of data.
FOUR KINDS OF COMPUTER
SUPERCOMPUTERS
MAINFRAME COMPUTERS
MINICOMPUTERS
MICROCOMPUTERS
any of a class of extremely powerful computers. The term is commonly applied to the fastest high-performance systems available at any given time.
SUPERCOMPUTERS
informally called a mainframe or big iron, is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing.
MAINFRAME COMPUTERS
computer that was smaller, less expensive, and less powerful than a mainframe or supercomputer but more expensive and more powerful than a personal computer.
MINICOMPUTERS
is a complete computer on a small scale, designed for use by one person at a time.
MICROCOMPUTERS
Two Classification of Microcomputers
PERSONAL COMPUTERS
WORKSTATIONS
Three key concepts of how computer works
- Purpose of a computer is to process data into information.
- Hardware and Software are two different entities.
- There are five basic operations of a computer. All computers use the same five basic operations: input, processing, storage, output, and communications.
are raw facts and figures that are processed into information
– for example, examinees’ score during board exam.
Data
is data that has been summarized or otherwise transformed for use in decision making.
– for example, the average score is used to determine the performance of the examinees.
Information
is a collection of code that drives a computer to perform a related group of tasks.
Software, or simply called programs
two types of software:
System Software
Application Software
are software run by the computer to manage or control the hardware.
Examples: operating system (OS), Basic Input Output System (BIOS), device driver, and compilers and associated programs.
System Software
are software that are related to a specific real-life situation in accomplishing a specific task. We encounter this type of software a lot every day. The smartphone industry calls it “apps”.
Examples: office software, database software, communication software, entertainment software
Application Software
five basic operations of a computer.
Input Operations.
Processing Operations.
Storage Operations.
Output Operations
Communication Operations
is whatever is put in (“input”) to a computer system.
Input Operations.
the set of activities and techniques used to manage and optimize the production of goods and services in an organization.
Processing Operations.
the set of activities and techniques used to manage and optimize the production of goods and services in an organization.
Storage Operations.
Two types of Storage Operations
Primary Storage and Secondary Storage
Primary storage is a key component of a computer system that enables it to function. Primary storage includes random access memory (RAM), read only memory (ROM), cache and flash memory.
Primary Storage
Secondary storage, sometimes called auxiliary storage, is non-volatile and is used to store data and programs for later retrieval. There are many kinds of secondary storage, each with advantages and disadvantages. Most storage devices use either magnetic or optical storage media.
Secondary Storage
Output Operations
Output has two types:
Softcopy and Hardcopy.
an electronic copy (or e-copy) of some type of data, such as a file viewed on a computer’s display, one that doesn’t exist in physical form or on paper, but is instead or transmitted as an email attachment.
Softcopy
printed on the paper and sometimes it is referred as permanent copy. We can touch the hard copy. We can say it is a physical copy. For example- News Paper, Book, Notebook, printed document files, etc.
Hardcopy.
any processes that allow you to communicate which feature a computer or computer program. The computer does this by sending data to one or more other computers, who decode the message and allow the recipient to send a message back.
Communication Operations

FIVE GENERATION OF COMPUTER
First Generation
1946 to 1958
Second Generation
1959 to 1964
Third Generation
1965 to 1970
Fourth Generation
1971 to Today
Fifth Generation
Today to Future
The technology behind the primary generation computers was a fragile glass device, which was called a vacuum tube. These computers were very heavy and really large. First-generation computers were used for calculation, storage, and control purpose.
First Generation
1946 to 1958
used the technology of transistors rather than bulky vacuum tubes. Another feature was the core storage. A transistor may be a device composed of semiconductor material that amplifies a sign or opens or closes a circuit.
Second Generation
1959 to 1964
technology envisaged a shift from huge transistors to integrated circuits, also referred to as IC. Here a variety of transistors were placed on silicon chips, called semiconductors. The most feature of this era’s computer was speed and reliability. IC was made from silicon and also called silicon chips
Third Generation
1965 to 1970
First microprocessors were used, the large-scale of integration LSI circuits built on one chip called microprocessors.
The computers using microchips were called microcomputers. This generation provided even smaller size of computers, with larger capacities
Fourth Generation
1971 to Today
It allows computers to behave like humans. It is often seen in programs like voice recognition, area of medicine, and entertainment. Within the field of game playing also it’s shown remarkable performance where computers are capable of beating human competitors.
Fifth Generation
Today to Future
