Basic computer operation ii

Types of booting

1. Cold booting (Hard booting): This is the process of turning the computer system

ON by pressing the power of the system unit and the monitor.

2. Warm booting (Soft booting): This is the process when the operating system alone is restarted (without being switched off) after a system crash or freeze. On PCs, warm booting is done by pressing the Control, Alt, and Delete keys simultaneously.

Both types of booting clear out (for the time being) the bugs, bombs, memory

conflicts , and other idiosyncrasies (peculiarities) of the operating system.

Difference between Cold Booting and Warm Booting

Cold Warm

1. Use of power-switch is involved in Cold 2.Booting While Warm Booting It involved short cut keys e.g. (CTRL+ALT+DEL)

3. Cold Booting is done when the system is already off Wille in Warm Booting CPU continuous running

4. CPU stops working in Cold Booting While CPU continuous running in Warm Booting

5. Memory and BIOS are reset Memory in Cold While Booting and BIOS are not reset in Warm Booting.

Types of the informative system include:
i. Data processing system
ii. A global positioning system (GPS). GPS is a satellite-
based navigating system.
Satellite communication
A satellite is an object that moves around a larger object.
Satellite communication, in telecommunication, is the use
of artificial satellites to provide communication links
between various points on Earth. Approximately 2,000

Telecommunication
Telecommunication is the transmission of information over
a significant distance, for communication. A basic
telecommunication system consists of three primary units;
a transmitter, a transmitting medium and the receiver.
Types of telecommunication systems include:
o Public Switched Telephone Network (PSTN) – landline.
o Mobile phone (GSM)
o Circuit Switched Packet Telephone (CSPT)
o Satellite Telephone
o Fixed Wireless Telephone
Data Network
Data network is an electronic communication process that
allows for orderly transmission and receptivity of data only.
Types of Data Networks
• Personal Area Network (PAN): It refers to the
interconnection of information technology devices or
gadgets within the environment of an individual user
(typically within 10 meters). PAN may be wired with the
computer such as USB and Firewire. A wireless Personal
Area Network (WPAN) can be made possible with network
technology such as infrared Data Association (irDA) and
Bluetooth.
• Local Area Network (LAN): A local area network is a
computer network covering a small local area, like a home,
office, or school.
• Metropolitan Area Network (MAN): MANs are large
computer networks usually spanning a large campus.
• Wide Area Network (WAN): WAN is a computer network
covering a broad geographical area.
• Internet: The internet is a worldwide network of
computers that share information
Information Systems
Information system is an integrated set of components for
collecting, storing, processing and communicating
information.
