A
  • Lower case “b.”
  • binary digit
  • when dealing with Data transfer it is written in bits
  • Single bit can store one of two digits 1 or 0
  • NIbble is 4 bits
    -Byte is 8 bits
  • data transfer (50 bps / 2 seconds = 25 bps). Number of seconds divided by total bits transferred

Q

Bit to Byte Converstions

Review this one long

A

8 bits = 1 Byte

Ex: 1000 b/ 8 B = 125

1 million bits (Mb)
1 million Bytes (MB)
1 billion bits (Gb)
1 billion Bytes (GB)
1 trillion bits (Tb)
1 trillion Bytes (TB)
1000 KB=1 MB
1000 MB=1 GB
1000 GB=1 TB

Q

USB overview

6

A
  • can daisy chain up to 127 devices per controller (i.e USB hub..)
  • Limitations…
    • Each port is controlled by a host controller
    • Same bandwidth for all devices (5 Gbps max speed with five devices connected all get 1 Gbps or two devices get 2.5 Gbps each)
    • If device doesnt support speed of host controller it will reduce to the speed it does support ( i.e if hub supports 5Gbps and cord/ device plugged in supports 2 Gbps then it will reduce to 2Gbps
  • Longer cables have higher chance of resistance and speed & signal deterioration
  • Shorter cables provide maximum performance
  • can transfer data and power

Q

Serial cable

4

A
  • came out before USB
  • Designed to replace USB
  • connected using DB25 or DB9. DB9 most commonly
  • A cable that sends data in ones and zeros in a straight line, but it can only send one bit at a time, which is measured at the speed of cables in bits
    per second
  • Typically used for older mice, keyboards, and external modems
  • Can only have one device plugged into one serial port.

Q

USB limitations

3

A
  • Longer cables have resistence and signal/speed deterioration (Shorter cables give maximum performance)

A
  • High Definition multimedia interface
  • The most widely used video interface in the world
  • Used with (i.e video, tv, computers)
    three types
  • Type A (Full size)

32
DisplayPort interface | 7
- developed by the video electronic standards association (Vesa) (represents Display tech companies) - competitor to HDMI - Same capabilities as HDMI - Labels as "DisplayPort," or "DP," on devices - Original DisplayPort supported only speeds of 2.7 Gbps, the latest version can go up to 80 Gbps. two forms - full size - Mini DP or M DP
33
- DisplayPort (Full SIze) - Has button on top and locking pin - only fit in one direction
34
- DVI-A - Supports analog
35
- DVI-D - Only supports Digital
36
- DVI-I - Supports analog and Digital signals - Had backwards compatible that could support older analog devices.
37
VGA | 4
- Video Graphics Array - 15 pin analog video interface port - D-Shaped - older technology - each pin controls a part of video. If one is broken you may have a monitor that has a colored tint to it.
38
Thunderbolt | 4
- A display interface that is also used for data transfer - popular with Apple devices - also on windows and Linux - 4 versions (versions 1, 2, 3, and 4
39
Thunder bolt 1 | 2
- Connector that looks like a mini DP backwards compatible with DP - port has has lightning bolt on
40
Thunderbolt 2 | 3
- 2nd Gen - Connector thats backwards compatible with DP - port has has lightning bolt on it
41
Thunderbolt 3 | 5
- Same connector as USB-C and fully compatible USB-C devices/ cables - Not all thunderbolt cords or ports work on USB-C cords or ports but all UBC-C cords work on thunderbolt - max length a meter (1.6ft) - 40 Gbps - All Thunderbolt 3 supports USB-C
42
Thunderbolt 4 | 4
- Type C connector - Backward compatible with USB 4 - 40 Gbps - max resolution of 8k - supports daisy chaining - Max length under 2 ft half a meter - Same connector as USB-C and fully compatible USB-C devices/ cables - Not all thunderbolt works on USB-C but all UBC-C works on thunderbolt
43
- Lighting cable - A specific proprietary connector that was created by apple their mobile devices - Fully reversable - On one end Lighting on the other USB standard or USB C
44
SATA | 5/ Overview
- Serial Advanced technology attachment - The standard cables are the main method of connecting a storage device to a motherboard inside of a desktop computer (One device at a time) - Serial: meaning one at a time - Used w/ storage devices such as internal hard drives,(HD) solid state drives (SDD) and optical drives - Cannot provide power and data on same cable
45
- SATA DATA - L- shaped 7 Pin connector - no power - Three types - Revision 1 (SATA 1.0) speeds to 1500Mbps/ 1.5Gbps/ 1 meter - Revision 2 (SATA 2.0) 3000Mbps/ 3 Gbps/ 1 meter - Revision 3 (SATA 3.0) 6000Mbps/ 6 Gbps (speed Limited by device)/ 1 meter - Revision 3 (SATA 3.2) 16000 Mbps/ 16 Gbps / 1 meter
46
- SATA Power - 15 pin - provides power - Connects directly to the power supply not the motherboard - no data
47
eSATA | 4
- External SATA - A SATA cable on the outside of the case - eSATA rev2 3 Gbps - eSATA rev3 6Gbps
48
IDE | 7
- Integrated Drive Electronics - before SATA - A ribbon cable that connects storage devices to computers (i.e HD and CD players) - Renamed as PATA (Parallel Advanced Technology Attachment) - 40 pin - parallel device (Support up to two devices at the same time - needs two cables to work (40 pin and Molex
49
- Molex power connector - Attach from the power supply directly to a device (Power supply --> to device) - 4 pin - Used with internal HD and CDROM (Optical drives) - Most modern devices supply with devices
50
SCSI | 7/ Review this card
- Small Computer Systems Interface - A legacy parallel bus connector that allows multiple devices to be Daisy chained together - legacy connector - Daisy chain similar to USB - Narrow SCSI 7 devices (40 Mbps) Wide SCSI 15 devices (320 Mbps) connecting SCSI - High density 68 w Molex - SCA 80 pin 320 Mbps
51
Summarize
Understand the meaning of the information learned in this course and then answer questions directly based on them. Example: which of the following versions of USB can operate at speeds of up to 5 Gb per second.
52
Summarize the basic cable types and their connectors, features, and purposes for the exam. Components: Speed: Power:
53
Customers can be tricked by internet speeds by….
Not knowing the difference between bits and bytes. For example, if you were purchasing an Internet plan And deciding between one Gb per second and 250 Megabytes per second one would think one Gb per second is more because it’s the next one up however one gigabit is equivalent to 125 MB so the customer should choose the 250 MB per second because it’s more than one Gb per second

SAS
- Serial attached SCSI - High performance data transfer Technology used mainly in enterprise environments/ Server farms for connecting storage devices to servers and workstations. - Data transfer speeds up to 24 Gb per second -Full duplex communication and high scalability - Backwards compatible with other SATA drives - Enterprise level reliability with features like a dual port architectures - 24/7 operation
58
DVI
- Digital Visual Interface - Used to support both analog and digital outputs - older (Late 90's) - three type (A, I, and D) - uses pins - evolution from VGA (Video graphics array)
