4. in this problem, we consider sending real-time voice from host a to host b over a packet-switchednetwork (voip). host a converts analog voice to a digital 64 kbps bit stream on the y. host a thengroups the bits into 56-byte packets. there is one link between hosts a and b; its transmission rate is2 mbps and its propagation delay is 10 msec. as soon as host a gathers a packet, it sends it to hostb. as soon as host b receives an entire packet, it converts the packet's bits to an analog signal. howmuch time elapses from the time a bit is created (from the original analog signal at host a) until thebit is decoded and played back as part of the analog signal at host b?

Communication is the exchange of information. true false

Consider the following declarations (1, 2, 3, 5, 7)class bagtype{public: void set(string, double, double, double, double); void print() const; string getstyle() const; double getprice() const; void get(double, double, double, double); bagtype(); bagtype(string, double, double, double, double); private: string style: double l; double w; double h; double price; }; a.) write the definition of the number function set so that private members are set according to the parametersb.) write the definition of the member function print that prints the values of the data membersc.) write the definition of the default constructor of the class bagtype so that the private member variables are initialized to "", 0.0, 0.0, 0.0, 0.0, respectively d.) write a c++ statement that prints the value of the object newbag.e.) write a c++ statement that declares the object tempbag of type bagtype, and initialize the member variables of tempbag to "backpack", 15, 8, 20 and 49.99, respectively

Which best describes the role or restriction enzymes in the analysis of edna a. to break dna into fragments that vary in size so they can be sorted and analyzed b. to amplify small amounts of dna and generate large amounts of dna for analysis c. to purify samples of dna obtained from the environment so they can be analyzed d. to sort different sizes of dna fragments into a banding pattern that can be analyzed
