Yes, it's true that RFID reader is a transmitter/receiver that reads the contents of RFID tags in the area. Also, it is comprised of one or more RFID tags, one or more RFID readers, and two or more antennas.

RFID stands for "radio-frequency identification," a technology that uses radio waves to read digital data encoded in RFID tags or smart labels (described below). In that information from a tag or label is recorded by a device and stored in a database, RFID is comparable to barcoding.

Contrary to systems that use barcode asset tracking software, RFID has a number of advantages. The most apparent difference is that although barcodes require alignment with an optical scanner, RFID tag data can be read without being in the line of sight.

An integrated circuit and an antenna make up an RFID tag. The protective substance that binds the parts together and shields them from various external factors is also a component of the tag.

The application determines the protective material. For instance, RFID-enabled employee ID badges are normally made of sturdy plastic, with the tag sandwiched in between the layers. RFID tags can be passive or active and come in a variety of sizes and shapes. Because they are more compact and affordable to employ, passive tags are the most popular. Before transmitting data, passive tags need to be "charged up" by the RFID reader.

The quantity of programming. The maximum number of processes that a single processor system can effectively support is the degree of multiprogramming.

CPU use was 13% and disk usage was 97%. Thrashing is caused by an excessively high disk utilization of 97% and a deficiently low CPU utilization of 13%. Executed processes spend a lot of time trying to get paged on the disk.

In general, a faster CPU has a higher clock speed. However, there are a lot of other variables at play.

For 802.11ac, wireless access points(AP) are three.  Wi-fi network coverage is up to 150 feet indoors; the range can be affected by building materials and other factors as well.

Requirements for capacity/throughput per user/application Knowing the user count will help with improving the above coverage estimates. When the location is intended for a high number of users, such as lecture halls, auditoriums, and stadiums, estimating the access point count using the number of people or devices is preferable.

For instance, a large sports arena with a rectangle-shaped seating bowl and 80,000 people has dimensions of 650 feet by 750 feet. An access point can easily cover 10,000 square feet thanks to outdoor WiFi signal dispersion, but we'll go with the more typical figure of 1600 square feet per access point from earlier. 487,500 square feet / 1600 = 305 access points when calculating coverage alone.

  totalsum=totalsum+num

  count=count+1

print("Total sum: {0}".format(totalsum))

print("Total number of numbers entered: {0}".format(count))

The initial variable is totalsum and count.

Then, we use looping function for totalsum is lower or equal to 200.

As long the totalsum is lower or equal to 200 the input always appear and user can input the value after that the new value is adding to totalsum and count is plus 1 to indicate number were entered.

Hence number of disk blocks = 2^120/2^9= 2^111 blocks

Hence there are 2^111 blocks in the disk and to manage free space among the blocks using bit vector, for each block 1 bit is used(value 1 - for free block or 0 - for allocated block). Therefore 2^111 bits is the size required to manage free space by using bit vector method.

Patents can only be given for things that are useful. The usefulness of the product being patented must be unique to that product; a general usefulness that applies to a wide range of products is not enough.

The novelty requirement is made up of two parts: novelty and statutory patentability barriers. The invention must be new, which means that no one else could have used it or known about it. The law says that the patented product couldn't have been sold or used in the US more than a year before the date of the patent application.

Any method, machine, product, mixture of materials, or improvement in the way things work can be patented. But the Supreme Court has said that you can't get a patent on abstract ideas, natural laws, or physical events.

Patents need not be evident. If the innovation goes beyond how the known functions of the prior art can be used in a predictable way, the patent claim is not clear.
