Every Windows version beginning with
Windows XP includes an installed
Remote Desktop Connection (RDC)
("Terminal Services") client
(mstsc.exe) whose version is
determined by that of the operating
system or last applied Windows Service
Pack.
The Terminal Services server is
supported as an official feature on
Windows NT 4.0 Terminal Server
Edition, Windows 2000 Server, all
editions of Windows XP except Windows
XP Home Edition, Windows Server 2003,
Windows Home Server, on Windows
Fundamentals for Legacy PCs, in
Windows Vista Ultimate, Enterprise and
Business editions, Windows Server 2008
and Windows Server 2008 R2 and on
Windows 7 Professional and above.
The RDC 7.0 for example contains these improvements and new features:
Multiple monitor support
Web Single Sign-On (SSO) and Web forms-based authentication
Access to personal virtual desktops by using RD Connection Broker
Access to virtual desktop pools by using RD Connection Broker
No differences from client side, it's even the different names of one product (I assume you not using TS client from early 200x).
It allow to access both Terminal Services (on Windows Server family) and Remote Desktop Connection (Windows XP/Vista/W7)
"Terminal Services Client" is the old name/version of the program called Remote Desktop Connection in more recent versions of Windows.
