Instructions for installing the HCPS security certificate for BYOD devices is as follows:
DRAM is asynchronous, meaning it operates independently of the CPU and the system bus’ clock cycle. SDRAM is synchronous, meaning its operation is dependent on the data bus’ clock cycle (as is the CPU). This synchronicity translates to faster data transfers between memory and the CPU.
SDR (Single Data Rate) SDRAM sends one bit per clock cycle. DDR (Double Data Rate) SDRAM sends two bits per clock cycle (on both the rising and the falling edges of each clock cycle). DDR2 achieves speeds twice as fast as DDR by using an internal clock that runs at double the speed.
The maximum transfer rate for a memory module can be calculated with the following formula:
Maximum Transfer Rate = (clock rate in MHz) x (number of bits) / 8 (the reason for dividing by 8 is to convert bits to Bytes)
Since DIMM modules transfer 64 bits at a time, “number of bits” will always be 64. Since 64 / 8 = 8, we can simplify this formula to:
Maximum Theoretical Transfer Rate = clock rate x 8
DDR2-400 / PC2-3200 Memory Module
Has a 400MHz clock cycle (real clock = 200MHz, doubled), so it can send/receive 400M bits per second
To determine Bandwidth (Transfer Rate), multiply:
400M (Hz) x 8 (bits) = 3200 MB/s

IPv6 Neighbor Solicitation Message
IPv6 Link-layer addresses appear to be the same as Link-local addresses (are they TECHNICALLY the same?)
Surveillance Self-Defense (SSD), a project of the Electronic Frontier Foundation (EFF), exists to answer two main questions: What can the government legally do to spy on your computer data and communications? And what can you legally do to protect yourself against such spying?
The Surveillance Self-Defense site aims to educate the American public about the law and technology of government surveillance in the United States, providing the information and tools necessary to evaluate the threat of surveillance and take appropriate steps to defend against it.
Can the first and last subnet be used? Absolutely.
In the past, using the first subnet (subnet zero) and the last subnet (all-ones subnet) was not supported. However, modern routers support both. For more information, see Subnet Zero and the All-Ones Subnet from Cisco.

Markdown is an easy alternative to HTML. It’s also a great way to organize notes, to-do lists, and other things. This article is a great introduction.
