Number Systems Conversion

Computer Communications

• Computer communications is the process of sharing data, programs, and information between two or more computers.
• Communication systems consist of:
• Sending and receiving devices
• Connection devices
• Data transmission specifications
• Communication channel

Connection Devices

• Act as an interface between the sending and receiving devices and the communication channel.
• Convert outgoing messages into packets that can travel across the communication channel.
• Reverse the process for incoming messages.

Modem

• Enables digital personal computers to communicate across different media.
• Modulation: the process of converting from digital to analog.
• Demodulation: the process of converting from analog to digital.

Data Transfer Rate

• Measured in millions of bits (megabits) per second (Mbps).
• The higher the speed, the faster you can send and receive information.

Number Systems

• Binary system: base 2, consists of 0 and 1.
• Decimal system: base 10, consists of 0 to 9.
• Octal system: base 8, consists of 0 to 7.
• Hexadecimal system: base 16, consists of 0 to 9 and A to F.

Conversions

• Convert from any system to decimal:
• Convert binary 0011101011 to decimal.
• Convert octal 456 to decimal.
• Convert hexadecimal 47AB1 to decimal.
• Convert from decimal to any system:
• Convert 98 decimal to binary.
• Convert 360 decimal to octal.
• Convert 1900 decimal to hexadecimal.
• Convert between number systems:
• Convert binary 11 100 111 to octal.
• Convert octal 347 to binary.
• Convert binary 1 1010 1000 1111 to hexadecimal.
• Convert octal 5401 to hexadecimal.

Connectivity

• Refers to linking people and resources.
• Enables computers to connect to other computers and share resources.
