Section 8.1 of the Texas Instruments NE555 datasheet [1] states a value of 100 kHz, and their website shows a value of 100 kHz in timer comparison tables. Signetics App Note 170 states that most devices will oscillate up to 1 MHz; however, when considering temperature stability, it should be limited to about 500 kHz. [ 2 ]
8-, 5.25-, 3.5-, 2.5-, 1.8- and 1-inch HDDs, together with a ruler to show the length of platters and read-write heads A newer 2.5-inch (63.5 mm) 6,495 MB HDD compared to an older 5.25-inch full-height 110 MB HDD. IBM's first hard drive, the IBM 350, used a stack of fifty 24-inch platters and was of a size comparable to two large refrigerators.
Cross section of a cat 5e cable. The Category 5e specification improves upon the Category 5 specification by further mitigating crosstalk. [9] The bandwidth (100 MHz) and physical construction are the same between the two, [10] and most Cat 5 cables actually happen to meet Cat 5e specifications even though they are not certified as such.

In 1995, Intel's P5 Pentium chip ran at 100 MHz (100 million cycles per second). On March 6, 2000, AMD demonstrated passing the 1 GHz milestone a few days ahead of Intel shipping 1 GHz in systems. In 2002, an Intel Pentium 4 model was introduced as the first CPU with a clock rate of 3 GHz (three billion cycles per second corresponding to ~ 0.33 ...
The Soviet Union started manufacturing TTL ICs with 7400-series pinout in the late 1960s and early 1970s, such as the K155ЛA3, which was pin-compatible with the 7400 part available in the United States, except for using a metric spacing of 2.5 mm between pins instead of the 0.1 inches (2.54 mm) pin-to-pin spacing used in the west.

The PowerBook 100 took 5.3 seconds to open a Microsoft Word document and 2.5 seconds to save it, while the Portable took 5.4 and 2.6 seconds respectively. [34] PC Week tested the battery life, which delivered 3 hours 47 minutes of use. [ 34 ]

The Valmet Sniper M86 was used as a basis for the Sako TRG sniper rifle line. Even though the TRG-21 obtained its origins from the successful Sako TR-6 target rifle and 1984–1986 development work for the hardly produced Valmet Sniper M86 rifle by the former Finnish state firearms company Valmet which merged with Sako, the 4.7 kg (10 lb 6 oz) TRG-21 was designed as a result of a thorough ...
