Recording the different characteristics of RAM

1. SRAM – SRAM or static RAM are RAM chips that retain information without the need for refreshing as long as the power is on. They are more expensive than traditional RAM.

2. DRAM – DRAM or dynamic RAM is the most commonly used type of system memory with access speeds ranging from 70 to 50 nanoseconds, requiring refreshing every few milliseconds.

3. DIMMS – DIMMS or dual in-line memory modules is a miniature circuit board that has a 64-bit path, unlike SIMMs, which have a 32-bit path.

4. Parity RAM – Parity RAM is 9-bit memory in which the 9th bit is used for error checking. Older DOS PCs almost always use parity chips.

5. Nonparity RAM – Nonparity RAM is slightly less expensive, 8-bit memory without error checking, used on Macs and recently in DOS PCs.

6. EDO RAM – EDO RAM or extended data output memory is a type of RAM that may be 10-20% faster than conventional RAM because it eliminates the delay before it issues the next memory address.

7. FPM RAM – FPM RAM or fast page mode RAM is an earlier memory mode used before the introduction of EDO memory.

8. Flash memory - Flash memory is a type of RAM that can electronically hold memory even when the power is off.

9. SDRAM – SDRAM or synchronous DRAM is an expensive memory that can operate at various speeds depending on the bus speed whereas SIMMs only operate at a single speed.

10. COAST – COAST or cache on a stick is a type of cache memory that consist of chips on a module available for pipelined burst synchronous SRAM.

Inspecting and labeling a laser printer cartridge

1. Primary corona - The primary corona is an element that applies a uniform negative charge (-600 volts) to prepare the drum for the new image.

2. Photo-sensitive drum – A photo-sensitive drum is the key component in a laser printer. A laser beam is used to write the image onto the drum, the drum then attracts the ink in the area where the image has been written.

3. Developing cylinder – The electrostatic image on the drum is developed into a visible image when toner from a developer cylinder is transferred to the discharged (-100 volt) areas of the drum. The developer cylinder has a magnetic core that attracts the iron in the toner. As the cylinder rotates, the doctor blade keeps the toner at a uniform height. The toner acquires a negative charge by rubbing against the developer cylinder. This negative charge causes the toner to be attracted to the relatively positive (-100 volt) areas of the drum that have been exposed to the laser light.

Inspecting and labeling a laser printer

4. Fuser – The toner is held on the paper by gravity and a weak electrostatic charge until it reaches the fuser assembly. Heat (180 C/356 F) and pressure applied by the fuser rollers melt the toner into the paper to produce a permanent image.Since the Photo-Sensitive Drum is 3.75 inches in circumference, the print cycle must be repeated several times to print one sheet of paper. Note that if temperature rises above 410F the printer will automatically shut itself down to cool off the fuser.

4.Paper tray – The paper tray is where new paper is stored until needed for printing.

5.Primary corona wire – The primary corona wire supplies power to the primary corona.

6.Transfer corona – The transfer corona produces a positive charge (+600 volts) on the back of the paper that pulls the toner off the drum to the paper. Once the toner is on the paper, a static charge eliminator reduces the paper’s charge.

7.Power supply – A printers power supply provides power to all parts of a printer.

8.Sensors (all) – Depending on the type of printers used for this lab exercise sensor location will vary.

9.Expansion slots - Depending on the type of printers used for this lab exercise sensor location will vary.

Activity

Identifying network components

1 a. DB-9 cable – DB-9 cables are most often used to communicate using a serial port.

b.DB-25 cable – This type of connections is often used for parallel or SCSI communications.

c.Centronics parallel data cable – A Centronics parallel data cable is used almost exclusively for communication between a printer and a parallel port on a PC.

d.RJ-25 – RJ-25 is a wiring standard that is used to interconnect phone and data lines.

e.RJ-11 – RJ-11 is the type of wiring connector used for today’s telephones.

f.RJ-14 – Slightly larger than a RJ-11 is used to interconnect phone and data lines.

g.RJ-45 – RJ-45 is the wiring connector that looks similar to an RJ-11 but is slightly larger. It is most often commissioned for interconnecting UTP LAN lines.

h.BNC – BNC or British Navel connector is most often employed in the computer industry to interconnect coaxial data lines.

i.BNCT – A BNCT is similar to a BNC connector except that it is T shaped, and is used to interconnect three different wires. A BNC is more barrel shaped and only connects two wires together.

j.PS2/MINI-DIN – The PS2/MINI-DIN are more commonly known today as the keyboard connectors.

k.ThickNet – ThickNet is a coaxial cable that is used to carry a data signal.

l.Unshielded twisted pair wire - Unshielded twisted pair wire or UTP is slightly thicker than telephone wire and is also used to carry a data signal.

m.Shielded twisted pair wire – Is the same as UTP except for it has an additional layer of shielding around the wire which gives it a coax look.

n.Network interface card – A network interface card or NIC is used to translate digital signals to electrical impulses that a computer can understand.

o.Hub – A hub is used to transfer ,and sometimes amplify, a signal from one wire to many others.

p.Router – A router is similar to hub but can also help distribute data packets to their destination.

q.Switch – A switch is a network device that selects a path or circuit for sending a unit of data to its next destination. A switch may also include functions of a router but it is not as complex.

r.Fiber optics – Fiber optic wire is a standard that employees a combination of light and wire to allow quick data transfers.

s.Network sniffer – A network sniffer is a tool that identify data packets while in transit.

t.Protocol analyzer – Similar to a network sniffer, a protocol analyzer can identify data packets while in transit but it can also trap and translate those data packets.

u.Time domain reflector – This is networking tool that can be used to test for termination among other things.

v.ISDN devices – ISDN devices are designed to communicate over a ISDN line, much in the same manner a modem is used to communicate over a phone line (Although ISDN devices don’t use the same standards as modems).
