BARK (Binär Aritmetisk Relä-Kalkylator, Swedish for "Binary Arithmetic Relay Calculator") was an early electromechanical computer. BARK was built using standard phone relays, implementing a 32-bit binary machine. It could perform addition in 150 ms and multiplication in 250 ms. It had a memory with 50 registers and 100 constants. It was later expanded to double the memory. Howard Aiken stated in reference to BARK "This is the first computer I have seen outside Harvard that actually works."
BARK was developed by Matematikmaskinnämnden (Swedish Board for Computing Machinery) a few years before BESK. The machine was built with 8000 standard phone relays, 80 km of cable and with 175,000 soldering points. It was completed in February 1950 at a cost of 400.000 Swedish kronor, became operational on April 28, and was taken offline on September 22, 1954. The engineers on the team led by Conny Palm were Harry Freese, Gösta Neovius, Olle Karlqvist, Carl-Erik Fröberg, G. Kellberg, Björn Lind, Arne Lindberger, P. Petersson and Madeline Wallmark.

Famous quotes containing the word bark:
“This house was but a slight departure from the hollow tree, which the bear still inhabits,being a hollow made with trees piled up, with a coating of bark like its original.”
—Henry David Thoreau (18171862)
“Sleep shall neither night nor day
Hang upon his penthouse lid;
He shall live a man forbid;
Weary sevn-nights, nine times nine,
Shall he dwindle, peak and pine;
Though his bark cannot be lost,
Yet it shall be tempest-tossed.”
—William Shakespeare (15641616)
“Let the palings of her bed
Be quince and box-wood overlaid
with the scented bark of yew.
That all the wood in blossoming,
May calm her heart and cool her blood
For losing of her maidenhood.”
—Hilda Doolittle (18861961)
