|Protocol||Rules of the road for network operation|
|RAM||The accessable, addressable, volatile electronic memory. Programs arrange themselves into memory. The operating system moderates between programs, to prevent conflicts.
3 basic kinds of RAM in your machine:
(Dynamic) DRAM up to 128MB; usually 4MB to 16MB.
(Static) SRAM up to 1MB; usually 256K
(Video) VRAM up to 2MB; usually 1MB
Pronounced like a male sheep.
|Random Access Memory
DRAM comes in various formats, capacities and speeds. When upgrading, stick with same speed and same manufacturer. Not all DRAM fits all machines. Modern DRAM comes on small 72 pin cards.
You need a lot of it. Most motherboards have a limited number of RAM slots. This means you must plan original purchase carefully, or you will create limits on future expansion, or have to replace chips.
The speed difference between 8MB and 16MB of RAM ($300) is more than between 75 and 100 MHz CPU clock ($500) w/8MB.
|ROM||The memory that you cannot access, but the computer can. ROM is programmed by the manufacturer.
|Read Only Memory. Your machine has 2 ROMs. Each may use more than 1 chip.
BIOS (normally electronically reprogrammable CMOS).
VIDEO BIOS (EEPROM).
|DISK||Nonvolatile mass storage.||HDD or FDD.|
|HDD||The mass storage device. A disk of magnetized metal sealed in a metal box. Fast, compared to a floppy disk or a backup tape, but slow compared to RAM.||Hard Disk or Hard Drive.
2 common varieties, requiring different "interfaces":
IDE (cheap for PC's).
SCSI (expensive for PC's).
|FDD||Removable mass storage. A plastic disk in a plastic sleeve, coated with barium ferrite (like the surface of a cassette tape).
Slow compared to Network.
Slow compared to HDD.
Fast compared to MODEM.
|Floppy or Floppy Disk.
Come in 2 common sizes: 3.5" and 5.25"; 6 common formats. 360KB, 1.2MD, 720KB,1.44MB, Old MAC, Newer MAC.
The current standard is 3.5" 1.44MB.
|FILE||Organized collection of digital data, readable by the program which created it, and if you are lucky, by some others, as well.||Linked information magnetically encoded on the surface of a FDD or HDD according to the format of the Disk and the FAT.|
|High density removable mass storage (fancy, expensive floppy disks). Various formats are not interchangeable.||Solution to transfer large files between non-networked machines.
Disks are generally very expensive in terms of $ per MB.
Data Transfer is faster than tape.
|TAPE BACKUP||Relatively obsolete method of creating archive of data files on inexpensive, portable medium. Allows off-site storage of essential business information.||Tape is very slow, capacity of individual tapes is very low. Cost of large HDD is now so low that backup requires multiple tapes.
Modern solution uses Digital Tape (generally look like Hi-8 cam-corder tapes). This allows up to 8GB of data on 1 tape.
the Microprocessor (CPU)
RAM (SIMM, SIPP, chips).
|In a PC, this is the Intel (80) 286, 386, 486, 586 (Pentium).
In a MAC, this is the Motorola (68) 020, 030, 040.
The issue of SX, DX, DX-2, DX-4 relates to how much power the chip has, how fast it runs, and what voltage it requires. Buy DX-2 or DX-4 unless someone gives you a very good reason to buy something else (DX-50 or Pentium).
|MATH-CHIP||Math Co-processer (MathChip)||Very useful upgrade to extend the life of fast 386 machines.|
|CARD||A printed circuit board you install in your PC to provide functions not included in Motherboard.||Adds functions not found on the motherboard, or updates functions provided on the motherboard.|
|UPS||Uninterruptable Power Supply.
Available in a range of sizes, with a range of features. If you run a Novell network, the advanced features may be important to you. Otherwise, all that matters is a test button and replaceable batteries.
|Basically, a UPS is a set of gel-cells or motorcycle type lead-acid batteries, a trickle charger, a voltage sensitive trigger, an alarm and a small switching power supply in a box a little bigger than a loaf of bread.
Switches within 1/4 cycle if line voltage goes above or below appropriate levels. Puts out clean, sine wave 120vac. Runs the computer for a little while during power outages. Howls when power goes out. You don't need big ones, or fancy ones, but you need one for every computer. ($100 -$200).
|MODEM||Card or external box that allows computers to connect to one another over conventional phone lines. Allows access to the Internet.||Buy 14.4 or 28.8. ($50 - $165) These are slow compared to moving files to and from disk, but much faster than previous modems (2400 - 9600 baud).|
|BIOS||Basic In Out System||Semi-programmable Chip-set which controls how the Computer connects to the rest of its components.
Latest versions of BIOS are called "Plug & Play". This means they are semi-automatic.
|Mother-board||The biggest "card" in your PC.||Holds the BUS and SLOTS. Most motherboards hold the CPU, CLOCK, BIOS and main and cache MEMORY.|
|Bus||16, 32 or 64 bit wide.||Electronics jargon. Refers to how "wide" (how many lanes move at once) the data highway inside your PC is.|
|Slot||The connector (on the motherboard) you plug a card into. Gives card access to the BUS.
ISA is pronounced EYE-sa
VESA is pronounced VEE-SA
|Cards come in several forms to fit into ISA (EISA) or VESA or PCI slots.|
