The two most important factors influencing share/security pricing are expected risk and projected return. In general, the projected average return is higher for riskier investments. Practically speaking, risk is the likelihood and magnitude of financial loss. The volatility of a fund's price over time is a good statistical proxy for this. Beta and standard deviation are two ways to describe market volatility. Beta measures the fund's volatility in comparison to other funds, whereas standard deviation measures the fluctuation in the fund's share price over time. Standard deviation, on the other hand, solely characterises the fund in question and not how ... Read More

The way we access the internet has been completely transformed by wireless technologies. We no longer live without wifi, which has made it possible to link some gadgets wirelessly to the internet. Yet, because wireless networks are intrinsically less secure than wired networks, numerous security protocols have been created to address this issue. WiFi Protected Access is one such protocol (WPA). Wired Equivalent Privacy (WEP), a security protocol, was intended to be replaced by WPA once it was discovered to be attackable. WPA was first introduced in 2003, and it immediately emerged as the de facto wireless network security protocol. ... Read More

Before knowing which connection is best for internet usage Fiber, Copper, or wireless, we need to know the connections available and their functionality in different environments. The connection that the user selects depends on the usage, cost, installation location, services needed from the internet, and speed of data transfer when uploading or downloading a file or large volumes like movies, software tools, applications, etc. All types of internet connection depend on the bandwidth on how many units (represented by Mbps or Gbps per second) are used for streaming any live video or how frequently the user downloads or accesses cloud ...

Time to Live (TTL) is a term used in computer science to describe how long a network packet will contain data. It is a value inside the packet header that represents the most router hops a packet may make before being dropped. When a packet travels through a network, it is forwarded from one router to another until it arrives at its final destination. The packet header's TTL value decreases with each router it passes through. The packet is dropped and not transmitted any further when the TTL is 0, halting its endless circulation. Time to Live (TTL) The TTL ... Read More
