Let's say you have a set of 100 pieces of data, which are all names. Now, if you want to find a specific name, "Kevin", you can find it in different ways. You could either go through each of the records one after another, or you could randomly generate a number, and check if that record is "Kevin", this is potentially faster than sequential access as "Kevin" could be the last record.
Random access memory is able to locate data in any order but serial access memory can only locate data in a sequence. Serial access memory will check the first memory cell for the data it needs, if it doesn't have the data it needs then it moves to the next memory cell until it finds the right data.
the main difference between a sequential access and a direct access is that in seq. access you have to traverse whole data which you stored at first.
and in direct access is that in which you can fetch any element from any position.
direct access can be well understood by using a link list.
in hardware also there is direct and sequential access;
direct=RAM(Random Access Memory)
seq.=SAM(sequential access memory)
Sequential access: Memory is organized into units of data, called records. Access must be made in a specific linear sequence.
Direct access: Individual blocks or records have a unique address based on physical location. Access is accomplished by direct access to reach a general vicinity plus sequential searching, counting, or waiting to reach the final location.
Random access: Each addressable location in memory has a unique, physically wired-in addressing mechanism. The time to access a given location is independent of the sequence of prior accesses and is constant.
If we discuss the different between these two forms of the signals that is; analog and digital then we should discuss it in different aspects such as working, their architectures, pros and cons as well. The major differences among the two signals are listed below

Modular programming:It is the act of designing and writing programs as interactions among functions that each perform a single well defined function,& which have minimal side effect interaction between them.It is heavily procedural.The focus is entirely on writing code(functions). Data is passive.Any code may access the contents of any data structured passed to it. Object Oriented programming:it is a programming paradigm using "objects"-data structures consisting of data fields & methods together with their interactions-to design applications and computer programs.programming techniques may include features such as data abstraction,encapsulation,messaging,modularity,polymorphism and inheritance.

The protection of memory allocated to one program from unauthorized access by another program is called memory protection. It may refer to protection among various programs in a multi tasking environment or in between OS and a program in a single tasking environment. It is needed to prevent a bug within a process from affecting other processes. It also prevents system crash in case of error on OS.
