Answer:
Yes. Pseudocode is an improvement over the IPO chart because it lays out the sequence of steps for a particular program
Explanation:
The input–process–output (IPO) chart is a widely used approach in systems analysis and software engineering for describing the structure of an information processing program or other process. The chart has three components (Input, Process and Output), and you write the description of each component in plain English, not code or mathematical formulas. 
Pseudocode is a procedure for solving a problem in terms of the actions to be executed and the order in which those actions are to be executed.
Pseudocode is an improvement over the IPO chart because it shows the step by step sequence to be followed by a particular program unlike the IPO chart which just break the program into Input, Process and Output.
 
        
             
        
        
        
Answer:
From DRAM to DDR4
Explanation:
RAM stands for <em>Random Access Memory.</em> In 1968, Mr. Robert Dennard at IBM's Watson Research obtained the patent for the one-transistor cell that will eventually substitute the old magnetic core memory allocated in computers of the time. By 1969 Intel released the TTL bipolar 64-bit SRAM (Static Random-Access Memory) as well as the ROM "Read Only Memory"; also in 1969 it evolved into "<em>Phase - change memory - PRAM - </em>". However this evolution was not commercialized, Samsung expressed its interest in developing it. In 1970 the first DRAM product was commercially available; it was developed by Intel. In 1971 it was patented EPROM; in 1978 George Perlegos developed EEPROM.
By 1983 a nice breakthrough happened with the invention of SIMM by Wang Labs. In 1993 Samsung came up with KM48SL2000 synchronous DRAM (SDRAM), this variation soon turned into an inductry standard.
In 1996 DDR began a revolution in the memory sector, then in 1999 RDRAM. Both DDR2 SDRAM. DDRR3 and XDR DRAM were commercialized. Finally in 2007 and 2014 the developments of DDR3 and DDR4 were available for the general public.
 
        
             
        
        
        
Answer:
Network. 
Explanation:
The Transmission Control Protocol/Internet Protocol (TCP/IP) model is a standard networking protocol which allows network devices such as routers, switches, and host computers to interconnect and communicate with one another over a network. The Transmission Control Protocol/Internet Protocol (TCP/IP) model comprises of four (4) layers and these includes;
I. Application layer. 
II. Transport layer. 
III. Internet layer. 
IV. Network layer. 
The network layer in the Transmission Control Protocol/Internet Protocol (TCP/IP) model is responsible for delivering data between two nodes.
Basically, this layer known as network layer is the fourth layer of the Transmission Control Protocol/Internet Protocol (TCP/IP) model and it is typically responsible for the transmission of packets from one network device to another.
