Mobile computer
"It's not a PC, but rather a microcomputer, a "Simple Inexpensive Mobile Computer." In short, a Simputer. It's the latest attempt to reach a kind of techno-humanist grail: a computer priced and designed for the billions of people who have yet to set foot in the wired wards of the Global Village. A computer, say its creators, for the masses."



graphical user interface (GUI)

is a type of user interface which allows people to interact with a computer and computer-controlled devices which employ graphical icons, visual indicators or special graphical elements called "widgets", along with text, labels or text navigation to represent the information and actions available to a user. The actions are usually performed through direct manipulation of the graphical elements. Use of this acronym led to creation of the neologism guituitive (an interface which is intuitive).

Keyboard

There are many types of keyboard, usually differentiated by the switch technology employed in their operation. Since there are so many switches needed (usually about 80-110) and because they have to be highly reliable, this usually defines the keyboard. The choice of switch technology affects key response (the positive feedback that a key has been pressed) and travel (the distance needed to push the key to enter a character reliably). Newer models use hybrids of various technologies to achieve greater cost savings.

An operating system (OS)
is the software that manages the sharing of the resources of a computer. An operating system processes raw system data and user input, and responds by allocating and managing tasks and internal system resources as a service to users and programs of the system.

A hard disk drive (HDD)
is a non-volatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces.

Computer network
A computer network is composed of multiple connected computers that communicate over a wired or wireless medium to share data and other resources. For instance, a home computer network may consist of two or more computers that share files and a printer using the network.

Ram
Random access memory (usually known by its acronym, RAM) is a type of data storage used in computers. It takes the form of integrated circuits that allow the stored data to be accessed in any order — that is, at random and without the physical movement of the storage medium or a physical reading head.
Internet
The Internet is a worldwide, publicly accessible series of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP). It is a "network of networks" that consists of millions of smaller domestic, academic, business, and government networks, which together carry various information and services, such as electronic mail, online chat, file transfer, and the interlinked Web pages and other documents of the World Wide Web.
Micro computer
a microcomputer (sometimes shortened to micro[2]) is most often taken to mean a computer with a microprocessor (µP) as its CPU. Another general characteristic of these computers is that they occupy physically small amounts of space.

Mini computer
Minicomputer (colloquially, mini) is a largely obsolete term for a class of multi-user computers that lies in the middle range of the computing spectrum, in between the largest multi-user systems (mainframe computers) and the smallest single-user systems (microcomputers or personal computers).

Electronics
Electronics is the study of the flow of charge through various materials and devices such as, semiconductors, resistors, inductors, capacitors, nano-structures, and vacuum tubes. All applications of electronics involve the transmission of power and possibly information.

Integrated circuit
In electronics, an integrated circuit (also known as IC, microcircuit, microchip, silicon chip, or chip) is a miniaturized electronic circuit (consisting mainly of semiconductor devices, as well as passive components) that has been manufactured in the surface of a thin substrate of semiconductor material.
Transister
Transister is an alternative rock band formed in late-1995 in Los Angeles by music business veterans from both the United States and the United Kingdom.

Vauum tube
In electronics, a vacuum tube, electron tube (inside North America), thermionic valve, or just valve (elsewhere); is a device used to amplify, switch, otherwise modify, or create an electrical signal by controlling the movement of electrons in a low-pressure space, often not tubular in form.

Intro

Computers are older than we are.

In terms of electrical hardware, computers have been around since the mid-1940’s. They were only powerful enough to calculate single simple equations back then. The very first computer ever invented took up an entire room, and it was called “ENIAC”, or Electronic Numerical Integrator and Computer. It was composed of 17,468 vacuum tubes, 7,200 crystal diodes, 1,500 relays, 70,000 resistors, 10,000 capacitors and around 5 million hand-soldered joints. It weighed 30 tons, was roughly 8 feet by 3 feet by 100 feet, took up 1800 square feet, and consumed 150 kW of power. It presented the results on punch cards which, when all compiled,relayed the information to the user.

Install operation

The Foolproof Way To Install Windows 98:

1. Get a Windows Startup Disk. To make one, on a running 98 system.

2. In your BIOS make sure your boot order is set to boot from floppy before the hard drive.

3. Insert Startup disk - start system - and answer 'Start Without CD-ROM Support' when prompted.

4. If you have multiple drives, you will want to make sure that you are on the correct current fixed disk drive, and switch it if necessary.

5. Create a Primary DOS partition and make it bootable.

6. Once FDISK is done it will tell you to reboot for changes.

7. Boot to BIOS, set the system boot order to boot from CD if you want to try a direct CD installation.

8. For CD Install: Insert Windows CD, remove floppy from drive and exit BIOS Good luck, system should start Windows install by formatting your drive.

Operating systems

1.Operating system ABCs
An Operating System, or OS, is a software program that enables the computer hardware to communicate and operate with the computer software. Without a computer Operating System, a computer would be useless.



2.Operating system types
As computers have progressed and developed so have the types of operating systems. Below is a basic list of the different types of operating systems and a few examples of Operating Systems that fall into each of the categories. Many computer Operating Systems will fall into more than one of the below categories.

Opuration system

An operating system (OS) is a set of computer programs that manage the hardware and software resources of a computer. An operating system processes raw system and user input and responds by allocating and managing tasks and internal system resources as a service to users and programs of the system. At the foundation of all system software, an operating system performs basic tasks such as controlling and allocating memory, prioritizing system requests, controlling input and output devices, facilitating networking and managing file systems. Most operating systems come with an application that provides an interface to the OS managed resources. These applications have had command line interpreters as a basic user interface but, since the mid-1980s, have been implemented as a graphical user interface (GUI) for ease of operation. Operating Systems themselves have no user interfaces; the user of an OS is an application, not a person. The operating system forms a platform for other system software and for application software. Windows, Linux, and Mac OS are some of the most popular OSes.
