 What is microprocessor? Deference between Intel and AMD processor?

Answer: A microprocessor is an integrated circuit (IC) which incorporates core functions of a computer’s central processing unit (CPU). It is a programmable multipurpose silicon chip, clock driven, register based, accepts binary data as input and provides output after processing it as per the instructions stored in the memory.Example: -Intel 4004 (The First Microprocessor), Intel 8085, Intel8086, Intel Pentium 4, Intel Core i7, AMD Athlon.

 
Deference between Intel and AMD processor:

 

Intel Processor	AMD Processor
Intel Processor marketed by Intel Corporation.	Advanced Micro Devices, (AMD) is an American multinational semiconductor company based in Santa Clara.
Intel’s speed always seems to be higherthen AMD	AMD speed is lower then intel.
Use less electrical power AMD Processor	Use more electrical power then intel Processor.
Intel Processor expensive.	AMD processors are much cheaper than Intel processors
Example: core 2 duo, Pentium, i3,i5,i7	Example:APU,Athlon X4,FX,Ryzen,Epyc,Opteron

 

Write short note on "video conferencing.

Answer: Video Conferencing A video conference is a live, visual connection between two or more people residing in separate locations for the purpose of communication. At its simplest, video conferencing provides transmission of static images and text between two locations. At its most sophisticated, it provides transmission of full-motion video images and high-quality audio between multiple locations.

The intangible benefits of video conferencing include more efficient meetings with the exchange of non-verbal communications and a stronger sense of community among business contacts, both within and between companies, as well as with customers. On a personal level, the face-to-face connection adds non-verbal communication to the exchange and allows participants to develop a stronger sense of familiarity with individuals they may never actually meet in person.
Consumer services -- like Apple's FaceTime, Google's Hangouts and Microsoft's Skype -- have made video conferencing ubiquitous on desktops and mobile devices that have an embedded camera.

What is male port and female port?

Answer: A male connector is commonly referred to as a plug and has a solid pin for a center conductor. A female connector is commonly referred to as a jack and has a center conductor with a hole in it to accept the male pin.

The names male and feminine are given to connectors by analogy with the male and feminine sexual organs of most mammals, during which the male part is inserted into the feminine. they're usually called genders instead of sexes, presumably because it sounds more polite, albeit this doesn't correspond with the excellence between gender and sex in humans because it is currently understood.

The RS-232 standard for serial communication was introduced in 1960. At the time, it had been wont to connect teletypewriters to modems. the quality defined two categories of equipment:

Data terminal equipment (DTE): teletypewriters, later electronic terminals, and computers

Data circuit-terminating equipment or digital communication equipment (DCE): modems

The RS-232 standard used a 25-pin connector. On DTE, data were transmitted on pin 3 and received on pin 2; on DCE these pins were swapped. DTE typically had male connectors, and DCE typically had female connectors. This gender convention was carried over to the smaller 9-pin connector that largely replaced the 25-pin one.

A serial cable to attach DTE to DCE (teletype to modem) would have a female connector on one end and a male connector on the opposite , and would be wired straight-through (pin 2 on one end would be connected to pin 2 on the opposite , etc.). this manner the info transmitted on pin 3 of the DTE would be received on pin 3 of the DCE, needless to say .

If you needed to attach two teletypewriters (or, later, computers) together, for testing or other purposes, you'll use a null-modem cable, with two male connectors. Pin 2 on one end of the cable would be wired to pin 3 on the opposite end (and the varied control signals would be similarly swapped). The gender of the connectors on the cable would tell you what quite cable it had been , and in theory, if the cable slot in both devices, it might work.

When computer terminals then personal computers replaced teletypes, the RS-232 standard continued to be wont to connect them to modems. But many other peripheral devices might be connected to computers using serial ports, including printers, mice, UPS units, laboratory instruments, etc. Eventually, as external serial modems disappeared, these peripherals became the most uses of the interface .

However, they didn’t always fall cleanly into the DTE/DCE categories—for example, a printer is DTE, but usually intended to be connected to a computer, so serial printers were usually wired an equivalent way as modems. Laboratory instruments are often wired either way, and sometimes the gender of the connector doesn't correspond to the pinout. As a result, anyone who spends time working with serial equipment will accumulate a box of straight-through and null-modem cables (male-female and male-male versions of both), null-modem adapters, and gender changers.

Nonetheless, computers have male serial ports due to the first convention of male connectors for DTE.

IBM in 1981 was the primary PC manufacturer to use a DB-25 female connector for the parallel printer interface. I don’t know why they picked female for the PC connector during this specific case—the decision was made a touch before my time. However, female D-sub connectors are usually thought to be more durable than male connectors (because it's easier to wreck the pins than the feminine contacts), so it often is sensible to place the more fragile male connector on the cable. additionally , since the 25-pin interface was just like the parallel interface apart from the gender, employing a female socket for the parallel interface would prevent someone from plugging a modem into the parallel interface or a printer into the interface by mistake.
