Study Notes
What is a Computer?
- An electronic device that operates and functions under the control of instructions (programs) stored in memory.
First Computers
- The abacus was the first calculating tool invented in 1822.
Charles Babbage
- A mathematician, philosopher, and inventor.
Computer Classifications
- Computers are classified into 5 categories:
- Supercomputers
- Mainframe computers
- Mid-Range computers
- Microcomputers
- Handheld computers
Supercomputers
- The most powerful computers with high capacity
- Used by large organizations like NASA and governments.
Mainframe Computers
- Powerful systems primarily used by organizations for bulk data processing, critical applications, and large-scale transaction processing.
- Can handle and manage vast amounts of data and support multiple users and applications simultaneously.
- Used in banking, telecommunications, transportation, and government.
Mid-Range Computers
- Also known as minicomputers.
- A class of computer between mainframe computers and PCs in terms of size, power, and capability.
- Designed to support multiple users and handle moderate to large-scale applications and data processing tasks.
- Used in manufacturing companies.
Microcomputers
- The most common and widely used computers today.
- Also known as desktop computers.
- Used at home, school, or the office.
Handheld Computers
- The smallest computers designed to fit into a person's hand.
- Also known as palmtop computers.
- Examples include smartphones, tablets, and handheld consoles.
Personal Computer (PC) Classifications
- Personal computers are classified into 6 categories:
- Desktop Computer
- Laptop Computer
- Multi-Touch
- Netbook
- Tablet PC
- Smartphone
Desktop Computer
- A personal computer set up on a desk or table.
Computer Networking Basics
- Computer networking refers to a network of computing devices that are able to share resources and exchange data.
- Computer networks can use cable or wireless connections to transmit data.
Network Cabling
- Network cabling is the medium that allows information to be transferred between network devices.
- Two main types of network cabling are straight-through and crossover.
Straight Through Cabling
- Straight-through Ethernet cables wire connections on both ends one-to-one.
- Straight-through cables are used to connect different types of hosts to a client.
Crossover Cabling
- Crossover cables reverse the reception and transmission pins on both ends, allowing the output of one computer to become the input of the other, and vice versa.
- Crossover cables are used to link two devices directly.
