Open: How Compaq Ended IBM's PC Domination and Helped Invent Modern Computing

The tale of Compaq is famous: 3 ex-Texas tools managers based Compaq with modest enterprise investment. simply 4 years later, Compaq was once at the Fortune 500 checklist, and, years after that, that they had passed $1 billion in annual profit. No corporation had ever completed those milestones so speedily.

Computing: A Business History

Noted platforms developer Lars Nielsen finds the dynamic mixture of innovation, pageant and (often eccentric) entrepreneurship that went to form today's tech panorama.

From the military's ENIAC of 1946 to the ripening of the internet and e-commerce, Nielsen's COMPUTING: A company background information the evolution of computing because it has impacted the types and practices of markets providers world wide.

Nielsen explains not just the advance of applied sciences, however the ongoing saga of strategic rivalries among such tech organisations as IBM, Cisco, Apple, Microsoft, Google and fb.

He surveys the increase and fall of businesses and structures from the early days of the mainframe while the likes of Sperry Rand and DEC laid unsuccessful siege to IBM's market-share, via to the period of home windows vs. Mac and past.

And he vividly depicts the intense yet usually rapacious personalities at the back of the contest that formed the company computing setting we all know at the present time.

We also accomplish the experiment many times by different number of switches, we don’t show the result here because of the space limitation. 1 Performance Test Connection Time Throughput and latency are important metrics to evaluate the performance of the network controller, however, since our testbed is currently composed of software POF switches, which are indeed the performance bottleneck of the testbed. For this reason, in order to estimate the performance of POFOX, we measure the time required by POFOX to shake hands with different number of POF switches.

PORT_STATUS READY to the neighbors of each switch at a fixed interval. Then it receives bounced back probing messages and discovers the topology of the network after unpacking the LLDP packets. The algorithm of topology discovery is shown in Algorithm 1. POFOX: Towards Controlling the Protocol Oblivious … 25 When a POF switch connects or disconnects POFOX, this_cycle and next_cycle updates the ports information.

Let A′ and B′ be the equivalent G2A of a TMA(n). Since the G2A is a two dimensional representation of TMA(n), hence the matrix-matrix addition algorithm can be expressed as shown in Algorithm 2. 2 Matrix-Matrix Multiplication Algorithms Let A and B be two TMA(n) of size [l1 ; l2 . lnÀ2 ; l; l] (Since for matrix multiplication ln−1 = ln). The algorithm for matrix-matrix multiplication C = A × B based on the TMA(n) is shown in Algorithm 3. Algorithm 4 shows the multiplication algorithm for G2A.
